The opening 31a is formed with a valve support 31b that supports a movable valve 37 (described later) suspended in a pendulum shape. The evaporator 30 is configured such that refrigerant (water) flowing through the refrigerant transfer pipe 54 is supplied into the container 31 through the opening 31a during the cooling operation.

  An opening 31 c connected to the refrigerant supply pipe 57 is formed on the lower end surface (the Z2 side surface) of the container 31. The evaporator 30 is configured such that the refrigerant stored in the liquid reservoir 34 (to be described later) of the container 31 is supplied to the refrigerant supply pipe 57 through the opening 31c.

  In addition, an opening 31 d connected to the refrigerant vapor transfer pipe 53 is formed on the side of the container 31 on the Y1 side. In the evaporator 30, during the cooling operation, the refrigerant vapor (water vapor) inside the container 31 is supplied to the refrigerant vapor transfer pipe 53 via the opening 31 d, and during the heating operation, the container 31 passes through the opening 31 d. The refrigerant vapor flowing through the refrigerant vapor transfer pipe 53 is supplied to the inside of the apparatus.

  In addition, in the container 31, a liquid distributor 32 (an example of a liquid distributor) and a plate-shaped heat exchanger 33 (heat transfer) are sequentially arranged from vertically upward (Z1 side) to vertically downward (Z2 side). An example) and a liquid reservoir 34 at the bottom of the container 31 are provided. Further, the opening 31d connected to the refrigerant vapor transfer conduit 53 is formed between the liquid distributor 32 and the heat exchanger 33 in the Z direction.

  The liquid distributor 32 is made of a sheet metal member, and is fixed inside the container 31 so as to spread in a surface direction formed by the X direction and the Y direction orthogonal to the vertical direction (Z direction). Further, at the center in the surface direction of the liquid distribution unit 32, a refrigerant is supplied through the opening 31a, and a collecting chamber 35 (an example of a primary collecting chamber) in which the supplied refrigerant is temporarily stored. Is provided.

  The collecting chamber 35 is formed in a concave shape that is recessed toward the Z2 side. Specifically, the collective chamber 35 has a concave spherical surface (curved surface) inner bottom surface 35 c, a bottom portion 35 a (an example of a first bottom portion) constituting the lower portion of the collective chamber 35, and an upper portion of the collective chamber 35. It is comprised from the circular opening part 35b which comprises. That is, the collecting chamber 35 is formed in a hemispherical shape having the center O (see FIG. 4). The center O is located substantially at the center of the liquid distributor 32. In addition, a valve support portion 31b that supports the movable valve 37 is positioned on a straight line that passes through the center O and extends in the Z direction.

  As shown in FIGS. 2 and 4, four holes 36 are provided in the bottom 35 a. The four holes 36 (an example of the first hole) are formed at substantially the same height position in the Z direction (height direction) at substantially equal angular intervals (intervals of approximately 90 degrees). The four hole portions 36 are both formed as circular holes having the same size. The four holes 36 are respectively provided on the X1 side, the X2 side, the Y1 side, and the Y2 side.

  Here, in the first embodiment, a movable valve 37 (an example of a movable valve body) is disposed inside the collecting chamber 35. The lower surface (Z2 side surface) of the movable valve 37 has a hemispherical shape like the inner bottom surface 35c of the collecting chamber 35, and the upper surface (Z1 side surface) is formed into a flat surface. . Further, the movable valve 37 is formed in a hemispherical shape having a smaller radius of curvature than the bottom portion 35 a, so that the movable valve 37 is disposed inside the collecting chamber 35 and at least partially blocks the hole 36 of the collecting chamber 35. It is formed in a shape that can be.

  Further, the movable valve 37 is configured such that a part thereof is in contact with the inner bottom surface 35c of the collecting chamber 35, but the whole is not in contact with the inner bottom surface 35c. Thereby, the movable valve 37 is configured not to completely block the hole 36.

  As shown in FIGS. 2 and 3, the movable valve 37 is formed in a pendulum shape by a flexible thread-like member 38 having both ends fixed to the valve support 31b and the center position on the upper surface of the movable valve 37, respectively. It is hung. Thereby, the movable valve 37 can be moved relative to the inner bottom surface 35c of the collecting chamber 35 by the inclination of the collecting chamber 35 and the inertial force while being suspended in a pendulum shape by the thread-like member 38.

Specifically, the movable valve 37 is formed of stainless steel, ceramics, Ti, or the like, which is a material having a specific gravity greater than that of the refrigerant (water). Thereby, it is possible to prevent the movable valve 37 from floating on the refrigerant stored in the collecting chamber 35 due to the specific gravity smaller than that of the refrigerant.

  The heat exchanging portion 33 has a flat outer shape, and is configured so that the cooling water flowing through the cooling water circuit portion 80 (see FIG. 1) can flow through the inside. Moreover, the heat exchange part 33 is being fixed inside the container 31 so that it may spread in the surface direction formed of a X direction and a Y direction.

  Further, the refrigerant stored in the vertically upper collecting chamber 35 is dropped onto the upper surface 33 a of the heat exchange unit 33 through the hole 36 during the cooling operation. The refrigerant dropped on the upper surface 33a of the heat exchange unit 33 spreads wet on the upper surface 33a of the heat exchange unit 33 so as to form a liquid film, and exchanges heat with the cooling water inside the heat exchange unit 33. It is configured. As a result, the refrigerant on the upper surface 33a of the heat exchanging unit 33 is evaporated by absorbing the heat of the cooling water to become refrigerant vapor (water vapor), and the cooling water is cooled by removing the heat. It is configured as follows. The generated refrigerant vapor is supplied to the refrigerant vapor transfer pipe 53 via the opening 31d located on the Z1 side with respect to the upper surface 33a of the heat exchange unit 33.

  On the other hand, during the heating operation, the refrigerant is not dropped onto the upper surface 33a of the heat exchanging portion 33 through the hole portion 36, but flows through the refrigerant vapor transfer pipe 53 into the container 31 through the opening portion 31d. The refrigerant vapor is supplied. And heat exchange is performed between the cooling water in the heat exchange part 33, and a refrigerant | coolant vapor | steam. As a result, the refrigerant vapor is cooled by taking heat away, becomes a refrigerant, and is stored in the liquid reservoir 34, and the cooling water is configured to be heated by absorbing the heat of the refrigerant vapor. ing.

  The liquid reservoir 34 is configured to store the refrigerant that has flowed down to the Z2 side from the four ends of the heat exchanger 33 in the X direction and the Y direction.

  Next, with reference to FIG. 5, the structure of the absorber 40 in 1st Embodiment is demonstrated roughly.

  The evaporator 30 and the absorber 40 have the same structure. Specifically, as shown in FIG. 5, the absorber 40 includes a container 41 corresponding to the container 31, and the upper end surface (the surface on the Z1 side) of the container 41 is connected to the absorbent liquid transfer line 55. A connected opening 41a is formed. A valve support 41b corresponding to the valve support 31b is formed in the opening 41a. The absorber 40 is configured such that a concentrated liquid of the absorbent flowing through the absorbent liquid transfer pipe 55 is supplied into the container 41 through the opening 41a during the cooling operation. The absorption liquid is an example of the “solution” in the present invention, and the opening 41a is an example of the “solution inlet” in the present invention.

  Further, an opening 41 c connected to the absorbing liquid transfer conduit 56 is formed on the lower end surface (the surface on the Z2 side) of the container 41. The absorber 40 is configured such that during the cooling operation, a dilute liquid of the absorbent stored in a liquid storage section 44 (to be described later) of the container 41 is supplied to the absorption liquid transfer pipe 56 through the opening 41c. Yes. In addition, an opening 41 d connected to the refrigerant vapor transfer pipe 53 is formed on the side of the container 41 on the Y1 side. The absorber 40 is configured such that refrigerant vapor (water vapor) flowing through the refrigerant vapor transfer pipe 53 is supplied into the container 41 through the opening 41d during the cooling operation.

  In addition, in the container 41, a liquid distributor 42, a flat plate heat exchanger 43, and a dilute solution of absorbing liquid are stored in order from the vertically upper side (Z1 side) to the vertically lower side (Z2 side). And a liquid reservoir 44 is provided. The liquid distributor 42, the heat exchanger 43, and the liquid reservoir 44 correspond to the liquid distributor 32, the heat exchanger 33, and the liquid reservoir 34 of the evaporator 30, respectively. That is, the liquid distributor 42 corresponds to the collecting chamber 35 and includes a hemispherical collecting chamber 45 in which a concentrated liquid of the absorbing liquid is stored and a movable valve 47 corresponding to the movable valve 37. The liquid distributor 42, the heat exchanger 43, and the collecting chamber 45 are examples of the “liquid distributor”, “heat transfer unit”, and “primary collecting chamber” of the present invention, respectively.

  The collecting chamber 45 has a bottom 45 a corresponding to the bottom 35 a and four holes 46 corresponding to the holes 36. The movable valve 47 is made of a material having a specific gravity greater than that of the absorbing liquid. In addition, the movable valve 47 can be moved relative to the inner bottom surface 45c of the collective chamber 45 by the inclination of the collective chamber 45 and the inertial force while being suspended in a pendulum shape by the thread-like member 48. It is configured. The bottom 45a, the hole 46, and the movable valve 47 are examples of the “first bottom”, “first hole”, and “movable valve body” of the present invention, respectively.

  Next, with reference to FIG. 2 to FIG. 4, the distribution of the refrigerant (water) in the normal time when the evaporator 30 in the first embodiment is not inclined and the inertial force does not work will be described.

  As shown in FIGS. 2 and 3, during the cooling operation, first, the refrigerant is dripped vertically downward (Z2 side) from the opening 31 c and stored in the collecting chamber 35. At this time, as shown in FIG. 4, the refrigerant in the collecting chamber 35 is substantially uniformly stored in the collecting chamber 35 so that the center is located on a straight line that passes through the center O of the collecting chamber 35 and extends in the vertical direction (Z direction). Is done. The movable valve 37 is arranged so that the center of the hemisphere is positioned on a straight line that passes through the center O and extends in the Z direction. The thread-like member 38 is disposed at a position overlapping a straight line that passes through the center O and extends in the Z direction.

  As a result, the four holes 36 are covered by the movable valve 37 by substantially the same area, so that the refrigerant passing through each of the four holes 36 has substantially the same amount (flow velocity). As a result, as shown in FIGS. 2 and 3, the refrigerant is dripped substantially uniformly downward from the four holes 36 and reaches the upper surface 33 a of the heat exchange unit 33. As a result, the refrigerant is distributed substantially evenly over the entire upper surface 33a of the heat exchanging portion 33 and spreads wet, so that the supplied refrigerant and the cooling water of the heat exchanging portion 33 are spread over a wide area of the upper surface 33a of the heat exchanging portion 33. Heat exchange between the two.

  Next, with reference to FIG. 6 and FIG. 7, distribution of the refrigerant (water) when the evaporator 30 is inclined in the first embodiment will be described. As an example, a case will be described in which the evaporator 30 is inclined along the Y direction so that the Y1 side is positioned vertically downward (Z2 side) and the Y2 side is positioned vertically upward (Z1 side).

  As shown in FIG. 6, during the cooling operation, first, the refrigerant is dropped from the opening 31 c to the Z2 side and stored in the collecting chamber 35. At this time, since the container 31 (liquid distributor 32) of the evaporator 30 is inclined along the Y direction so that the Y1 side is located on the Z2 side and the Y2 side is located on the Z1 side, the refrigerant in the collecting chamber 35 is In accordance with the inclination of the liquid distributor 32, the liquid is stored in the collecting chamber 35 in a state of being biased toward the Y1 side from the center O of the collecting chamber 35. That is, the amount of the refrigerant decreases on the upper side (Y2 side) of the collecting chamber 35, and the amount of the refrigerant increases on the lower side (Y1 side) of the collecting chamber 35. For this reason, when the movable valve 37 is not provided (when the deviation of the refrigerant dripping amount is not adjusted), the amount (flow velocity) of the refrigerant passing through the Y1 side hole 36 is the Y2 side hole 36. As a result, a large amount of refrigerant is dripped on the Y2 side in the upper surface 33a of the heat exchanging portion 33, but not much refrigerant is dripped on the Y1 side. For this reason, due to the inclination of the evaporator 30, the dripping amount of the refrigerant on the lower side (Y1 side) of the inclination increases, and as a result, the dripping amount of the refrigerant is biased.

  On the other hand, in the first embodiment, the movable valve 37 is suspended in a pendulum shape, so that the position thereof does not change substantially regardless of the inclination of the liquid distributor 32. Accordingly, the movable valve 37 moves to the Y1 side relative to the inner bottom surface 35c of the collecting chamber 35 due to the inclination of the collecting chamber 35. As a result, as shown in FIG. 7, the movable valve 37 greatly blocks the Y1 side hole 36 with a large amount of refrigerant, while small or does not block the Y2 side hole 36 with a small amount of refrigerant. In addition, it is arranged in the collecting chamber 35. Therefore, the refrigerant is less likely to pass through the hole 36 on the Y1 side, but more easily passes through the hole 36 on the Y2 side. Even when the hole 36 is not completely blocked, if the hole 36 is largely covered, the pressure loss at the time of passing through the hole 36 becomes large, so that the refrigerant does not easily pass. As a result, the deviation of the dripping amount of the refrigerant dripped from the four holes 36 is sufficiently adjusted.

  Thus, when the refrigerant is dropped downward from the four holes 36 and reaches the upper surface 33a of the heat exchange unit 33, the refrigerant is more from the Y2 side hole 36 than when the movable valve 37 is not provided. While a small amount of refrigerant is dropped from the hole 36 on the Y1 side. Here, since the heat exchanging portion 33 is also inclined along the Y direction so that the Y1 side is located on the Z2 side and the Y2 side is located on the Z1 side, similarly to the container 31, it is dropped from the hole portion 36 on the Y2 side. The obtained refrigerant moves on the upper surface 33a of the heat exchanging portion 33 from the Y2 side to the Y1 side and spreads wet. Thereby, even if a small amount of refrigerant is dropped on the Y1 side of the upper surface 33a, the refrigerant is supplied from the Y2 side of the upper surface 33a on which a large amount of refrigerant has been dropped. As a result, even when the evaporator 30 is inclined, it is possible to efficiently distribute the refrigerant over a wide range of the upper surface 33a of the heat exchange unit 33. Then, as in the normal state, heat exchange is performed between the supplied refrigerant and the cooling water of the heat exchange unit 33 in a wide range of the upper surface 33a of the heat exchange unit 33.

  Next, with reference to FIG. 7 and FIG. 8, the distribution of the refrigerant (water) when the inertia force of the evaporator 30 in the first embodiment is generated will be described. As an example, a case will be described in which an inertial force is generated on the Y1 side by accelerating the vehicle on which the absorption heat pump device 100 is installed on the Y2 side.

  As shown in FIG. 8, during the cooling operation, first, the refrigerant is dripped from the opening 31c to the Z2 side and slightly to the Y1 side by the inertial force, and is stored in the collecting chamber 35. At this time, the refrigerant in the collecting chamber 35 is stored in the collecting chamber 35 in a state of being biased to the Y1 side with respect to the center O of the collecting chamber 35 due to inertial force. That is, the amount of refrigerant decreases on the Y2 side of the collecting chamber 35, and the amount of refrigerant increases on the Y1 side of the collecting chamber 35.

  Here, in the first embodiment, the movable valve 37 is suspended in a pendulum shape, and thus moves to the Y1 side relative to the inner bottom surface 35c of the collecting chamber 35 by inertial force. As a result, as in the case of the inclination, as shown in FIG. 7, the movable valve 37 largely closes the Y1 side hole 36 with a large amount of refrigerant, while reducing the Y2 side hole 36 with a small amount of refrigerant. It arrange | positions in the gathering chamber 35 so that it may block or may not block. Therefore, the refrigerant is less likely to pass through the hole 36 on the Y1 side, but more easily passes through the hole 36 on the Y2 side. As a result, the deviation of the dripping amount of the refrigerant dripped from the four holes 36 is sufficiently adjusted.

  Thereby, when the refrigerant is dripped slightly downward from the four holes 36 and slightly toward the Y1 side and reaches the upper surface 33a of the heat exchange unit 33, the Y2 side is compared with the case where the movable valve 37 is not provided. While a large amount of refrigerant is dripped from the hole 36, a small amount of refrigerant is dripped from the hole 36 on the Y1 side. Here, the refrigerant droplets on the upper surface 33a of the heat exchanging portion 33 also move and move wet on the upper surface 33a of the heat exchanging portion 33 from the Y2 side to the Y1 side due to inertial force. Thereby, even if a small amount of refrigerant is dropped on the Y1 side of the upper surface 33a, the refrigerant is supplied from the Y2 side of the upper surface 33a on which a large amount of refrigerant has been dropped. As a result, even when an inertia force is generated, it is possible to efficiently distribute the refrigerant over a wide area of the upper surface 33a of the heat exchange unit 33. Then, as in the normal state, heat exchange is performed between the supplied refrigerant and the cooling water of the heat exchange unit 33 in a wide range of the upper surface 33a of the heat exchange unit 33.

  The distribution of the absorbing liquid in the absorber 40 is the same as the distribution of the refrigerant (water) in the evaporator 30 and thus will not be described.

  In the first embodiment, the following effects can be obtained.

  In the first embodiment, as described above, the evaporator 30 has a shape capable of closing the hole portion 36 of the collecting chamber 35, and the inclination of the collecting chamber 35 and the inertial force of the collecting chamber 35. A movable valve 37 that is movable relative to the inner bottom surface 35c is provided. Thus, the movable valve 37 is moved relative to the inner bottom surface 35c of the collecting chamber 35 by the inclination of the collecting chamber 35 and the inertial force, so that the movable valve 37 is dropped in the collecting chamber 35. It can be moved so as to block the hole 36 on the side (Y1 side) where the amount of refrigerant is large in accordance with the amount deviation. As a result, it is possible to make it difficult for the refrigerant to pass through the hole 36 on the Y1 side where a large amount of refrigerant is likely to be dripped. Therefore, the deviation of the refrigerant dripping amount due to the inclination and inertia force is sufficiently adjusted. The refrigerant can be distributed in a state. Thereby, when the refrigerant is sufficiently distributed, the pump member and the circulation pipe for returning the refrigerant in the evaporator 30 to the opening 31a again to supplement the insufficient refrigerant distribution become unnecessary. The configuration of the evaporator 30 can be simplified.

  In the first embodiment, the absorber 40 has a shape capable of closing the hole 46 of the collecting chamber 45, and the inner bottom surface 45c of the collecting chamber 45 due to the inclination of the collecting chamber 45 and the inertial force. A movable valve 47 is provided that is movable relative to. Thereby, similarly to the evaporator 30, the absorbing liquid can be distributed in a state where the deviation of the dripping amount of the absorbing liquid due to the inclination and inertia force is sufficiently adjusted.

  In the first embodiment, the movable valve 37 (47) moves relative to the inner bottom surface 35c (45c) of the collecting chamber 35 (45) due to the inclination of the collecting chamber 35 (45) and the inertial force. By doing so, the drive part for driving the movable valve 37 (47) is not necessary, so that the configuration of the evaporator 30 (absorber 40) can be simplified.

  In the first embodiment, the movable valve 37 (47) is suspended in a pendulum shape, and the inner bottom surface 35c of the collecting chamber 35 (45) is caused by the inclination of the collecting chamber 35 (45) and the inertial force. It is configured to move relative to (45c). As a result, the movable valve 37 (47) suspended in a pendulum shape is moved relative to the inner bottom surface 35c (45c) of the collecting chamber 35 (45) due to the inclination of the collecting chamber 35 (45) and the inertial force. It can be moved reliably. Further, since the movable valve 37 (47) is suspended in a pendulum shape, the movable valve 37 (47) can be prevented from being detached from the liquid distributor 32 (42).

  In the first embodiment, the inner bottom surface 35c (45c) of the bottom portion 35a (45a) has a concave spherical shape, so that the movable valve 37 (47) suspended in a pendulum shape having a spherical movement locus is provided. It can be relatively moved relatively along the spherical inner bottom surface 35c (45c).

  Moreover, in 1st Embodiment, in the evaporator 30 of the absorption heat pump apparatus 100, it comprises so that the refrigerant | coolant which passed the hole 36 of the collection chamber 35 may be supplied to the heat exchange part 33. FIG. Thereby, in the absorption heat pump device 100, the refrigerant can be distributed to the heat exchange unit 33 in a state where the deviation of the dripping amount of the refrigerant dripped from the plurality (four) of the hole portions 36 is sufficiently corrected. Thereby, the heat exchange between the refrigerant whose bias is corrected and the heat exchange unit 33 can be efficiently performed.

  Moreover, in 1st Embodiment, in the absorber 40 of the absorption heat pump apparatus 100, it comprises so that the absorption liquid which passed the hole 46 of the gathering chamber 45 may be supplied to the heat exchange part 43. FIG. Thereby, in the absorption heat pump apparatus 100, the absorbing liquid can be distributed to the heat exchanging unit 43 in a state where the deviation of the dropping amount of the absorbing liquid dripped from the plurality (four) of the holes 46 is sufficiently corrected. . Thereby, the heat exchange between the absorbing liquid whose bias has been corrected and the heat exchange unit 43 can be efficiently performed.

  In the first embodiment, the movable valve 37 (47) suspended in a pendulum form on the thread-like member 38 (48) is formed of a material having a specific gravity larger than the specific gravity of the refrigerant (absorbing liquid). Even when 37 (47) is suspended from the thread-like member 38 (48), the movable valve 37 (47) can be prevented from floating on the refrigerant (absorbing liquid). Thereby, it can suppress that the hole part 36 (46) is not obstruct | occluded by the movable valve 37 (47).

  In the first embodiment, the movable valve 37 (47) has a spherical shape capable of closing the hole 36 (46), which is a circular hole. It is possible to prevent 36 (46) from being blocked. Further, by forming the hole 36 (46) into a circular hole, the hole 36 (46) can be easily formed in the bottom 35a (45a) as compared with the case where the hole 36 (46) has a complicated shape. Can be formed.

(Second Embodiment)
Next, a second embodiment will be described with reference to FIGS. In the second embodiment, an example in which a liquid distributor 239 is further provided vertically below the liquid distributor 232 in addition to the configuration of the evaporator 30 of the first embodiment will be described. Note that in the second embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

  In the evaporator 230 of the second embodiment, as shown in FIGS. 9 and 10, a liquid distributor 239 (an example of a liquid distributor) is installed on the Z2 side of a liquid distributor 232 (an example of a liquid distributor). Yes. In addition, four holes 236 are provided at substantially equal angular intervals on the bottom 35 a of the collecting chamber 35 of the liquid distributor 232. As shown in FIG. 11, the four holes 236 are provided on the X1 side and the Y1 side, the X2 side and the Y1 side, the X1 side and the Y2 side, and the X2 side and the Y2 side, respectively.

  As shown in FIGS. 9 and 10, the liquid distributor 239 includes a bottom 239a (an example of a second bottom) and a pair of partition walls 239b and 239c extending from the bottom 239a in the Z1 direction. The bottom 239a is fixed to the inside of the container 31 so as to spread in the surface direction formed by the X direction and the Y direction. Further, the bottom portion 239a and the inner surfaces of the four side portions of the container 31 form a collecting chamber 239d (an example of a secondary collecting chamber) in which the refrigerant that has passed through the collecting chamber 35 is stored.

  The partition wall 239b is formed so that the center in the X direction of the bottom 239a (container 31) extends in the Y direction from the Y1 side of the container 31 to the Y2 side. The partition wall 239c is formed so that the center in the Y direction of the bottom 239a extends in the X direction from the X1 side of the container 31 to the X2 side. As a result, the collecting chamber 239d of the liquid distributor 239 is partitioned into the X1 side and the Y1 side, the X2 side and the Y1 side, the X1 side and the Y2 side, and the X2 side and the Y2 side, respectively. A plurality of (four) rooms 239e are provided.

  Accordingly, in the second embodiment, the four chambers 239e are provided so as to correspond to the four holes 236 of the liquid distribution unit 232 provided on the Z1 side of the liquid distribution unit 239, respectively. And it is comprised so that the refrigerant | coolant from the corresponding hole 236 may be stored by each chamber 239e by each refrigerant | coolant dripping from the hole 236 corresponding to each of the four chambers 239e. Further, the four rooms 239e have the same shape, and as a result, have the same volume.

  The bottom 239a is provided with a plurality of holes 239f through which the refrigerant can pass. The holes 239f are formed so as to have a smaller diameter than the holes 236 of the liquid distributor 232, and are formed in the four chambers 239e by the same number. As a result, when the same amount of refrigerant is stored in each of the four chambers 239e, each chamber 239e is substantially the same amount (flow velocity) through the plurality of holes 239f (an example of the second hole). Is configured such that the refrigerant is dropped to the Z2 side.

  The heat exchange part 233 (an example of a heat transfer part) has a plurality (three) of heat transfer tubes 233b arranged so as to be aligned in the X direction. The three heat transfer tubes 233b are configured such that cooling water (not shown) flowing through the cooling water circuit unit 80 can flow through the inside. The heat transfer tube 233b is formed so as to extend in the Y direction and has a folded structure laminated in the Z direction.

  Further, the refrigerant stored in the upper collecting chamber 239d is configured to be dropped into the heat transfer tube 233b through the plurality of holes 239f during the cooling operation. The refrigerant dripped onto the heat transfer tube 233b is configured to wet and spread on the heat transfer tube 233b so as to form a liquid film, and to exchange heat with the cooling water inside the heat transfer tube 233b.

  In addition, since the other structure of 2nd Embodiment is the same as that of the said 1st Embodiment, description is abbreviate | omitted.

  Next, with reference to FIG. 10, the distribution of the refrigerant (water) at the normal time of the evaporator 230 in the second embodiment will be described. In addition, description is abbreviate | omitted regarding the content similar to the said 1st Embodiment.

  As shown in FIG. 10, similarly to the evaporator 30 of the first embodiment, the refrigerant stored in the collecting chamber 35 is dropped almost uniformly downward from each of the four holes 236, and Is stored in the room 239e. At this time, the amount of refrigerant supplied to the four chambers 239e is substantially the same. Thereby, a refrigerant | coolant is dripped at the heat exchanger tube 233b substantially equally from the whole gathering chamber 239d. As a result, the refrigerant is distributed substantially evenly throughout the heat transfer tube 233b, so that heat exchange is performed between the supplied refrigerant and the cooling water of the heat transfer tube 233b in a wide range of the heat transfer tube 233b.

  Next, with reference to FIG. 12 and FIG. 13, distribution of the refrigerant (water) when the evaporator 230 is inclined in the second embodiment will be described. As an example, a case will be described in which the evaporator 230 is inclined along the Y direction so that the Y1 side is positioned downward (Z2 side) and the Y2 side is positioned upward (Z1 side).

  As shown in FIG. 12, during the cooling operation, first, the refrigerant is dripped vertically downward (Z2 side) from the opening 31c and stored in the collecting chamber 35. At this time, as shown in FIG. 13, as in the evaporator 30 of the first embodiment, the refrigerant in the collecting chamber 35 is biased toward the Y1 side from the center O of the collecting chamber 35 in accordance with the inclination of the liquid distributor 232. It is stored in the collecting chamber 35 in a state. The movable valve 37 moves to the Y1 side relative to the inner bottom surface 35c of the collecting chamber 35 due to the inclination of the collecting chamber 35, so that the movable valve 37 moves the pair of holes 236 on the Y1 side to the Y2 side. It arrange | positions in the assembly chamber 35 so that it may block larger than a pair of hole part 236 of the side. As a result, the refrigerant is unlikely to pass through the pair of holes 236 on the Y1 side, but easily passes through the pair of holes 236 on the Y2 side. As a result, the deviation of the dripping amount of the refrigerant dripped from the four holes 236 is sufficiently adjusted.

  Thereby, as shown in FIG. 12, a refrigerant | coolant is dripped below from the four hole parts 236, and is stored in each corresponding room 239e. At this time, the amount of refrigerant supplied to the pair of chambers 239e on the Y2 side is larger than the amount of refrigerant supplied to the pair of chambers 239e on the Y1 side. Accordingly, the amount of refrigerant stored in the pair of Y2 side chambers 239e is larger than the amount of refrigerant supplied to the pair of Y1 side chambers 239e, whereby a plurality of holes in the pair of Y2 side chambers 239e are obtained. The amount (flow velocity) of the refrigerant passing through the portion 239f is larger than the amount of refrigerant passing through the plurality of holes 239f of the pair of chambers 239e on the Y1 side. As a result, a large amount of refrigerant is dropped onto the heat transfer tube 233b from the Y2 side of the collecting chamber 239d, while a small amount of refrigerant is dropped onto the heat transfer tube 233b from the Y1 side of the collecting chamber 239d.

  Here, since the heat transfer tube 233b is also inclined along the Y direction so that the Y1 side is located on the Z2 side and the Y2 side is located on the Z1 side, similarly to the container 31, it is dropped from the Y2 side of the collecting chamber 239d. The refrigerant moved wet on the surface of the heat transfer tube 233b from the Y2 side to the Y1 side and spreads. Thus, even when a small amount of refrigerant is dropped on the Y1 side of the heat transfer tube 233b, the refrigerant is supplied from the Y2 side of the heat transfer tube 233b where a large amount of refrigerant has been dropped. As a result, even when the evaporator 230 is inclined, it is possible to efficiently distribute the refrigerant over a wide area on the surface of the heat transfer tube 233b. And heat exchange is performed between the supplied refrigerant and the cooling water of the heat transfer tube 233b in a wide range of the heat transfer tube 233b.

  Next, with reference to FIG. 13 and FIG. 14, the distribution of the refrigerant (water) when the inertial force of the evaporator 230 in the second embodiment is generated will be described. As an example, a case where an inertial force is generated on the Y1 side will be described.

  As shown in FIG. 14, during the cooling operation, first, the refrigerant in the collecting chamber 35 is stored in the collecting chamber 35 while being biased to the Y1 side with respect to the center O of the collecting chamber 35 due to inertial force. The valve 37 moves to the Y1 side relative to the inner bottom surface 35c of the collecting chamber 35 by inertial force. Thus, as in the case of the inclination, the movable valve 37 gathers so that the pair of holes 236 on the Y1 side where the amount of refrigerant is large is larger than the pair of holes 236 on the Y2 side where the amount of refrigerant is small. Arranged in the chamber 35. As a result, the refrigerant is unlikely to pass through the pair of holes 236 on the Y1 side, but easily passes through the pair of holes 236 on the Y2 side. Therefore, the deviation of the dripping amount of the refrigerant dripped from the four holes 236 is sufficiently adjusted.

  Thus, as in the case of the inclination, the amount of refrigerant stored in the pair of rooms 239e on the Y2 side becomes larger than the amount of refrigerant supplied to the pair of rooms 239e on the Y1 side. While a large amount of refrigerant is dropped from the Y2 side to the heat transfer tube 233b, a small amount of refrigerant is dropped from the Y1 side of the collecting chamber 239d to the heat transfer tube 233b. Further, the refrigerant droplets on the heat transfer tube 233b are also spread by wetting by moving the heat transfer tube 233b from the Y2 side to the Y1 side due to inertial force. Thus, even when a small amount of refrigerant is dropped on the Y1 side of the heat transfer tube 233b, the refrigerant is supplied from the Y2 side of the heat transfer tube 233b where a large amount of refrigerant has been dropped. As a result, even when inertial force is generated, it is possible to efficiently distribute the refrigerant over a wide area on the surface of the heat transfer tube 233b. And heat exchange is performed between the supplied refrigerant and the cooling water of the heat transfer tube 233b in a wide range of the heat transfer tube 233b.

  In the second embodiment, the following effects can be obtained.

  In the second embodiment, as described above, the evaporator 230 has a shape capable of closing the hole 236 of the collecting chamber 35 and the inclination of the collecting chamber 35 and the inertial force of the collecting chamber 35. A movable valve 37 that is movable relative to the inner bottom surface 35c is provided. Thereby, similarly to 1st Embodiment, a refrigerant | coolant can be distributed in the state which fully adjusted the deviation of the dripping amount of the refrigerant | coolant resulting from an inclination and an inertia force.

  In the second embodiment, as described above, the collection chamber 239d of the liquid distribution unit 239 installed below the liquid distribution unit 232 is partitioned so as to correspond to the four holes 236 of the liquid distribution unit 232, respectively. The four chambers 239e are provided, and a plurality of holes 239f through which the refrigerant can pass are provided in the four chambers 239e. As a result, due to the collective chamber 239d installed below the collective chamber 35, the temporary (instantaneous) inclination of the collective chamber 35 and the temporary bias of the refrigerant due to the inertial force directly affect the distribution of the refrigerant. Can be suppressed. Thereby, a refrigerant | coolant can be distributed more correctly. In addition, since the collecting chamber 239d includes four chambers 239e corresponding to the plurality of holes 236 of the collecting chamber 35, the distribution of the refrigerant passing through the holes 236 in a state where the deviation of the amount of refrigerant dropped is adjusted. Since the situation can be reliably reflected in each of the chambers 239e of the collecting chamber 239d corresponding to the hole 236, even if the collecting chamber 239d is provided, the refrigerant can be adjusted in a state in which the deviation of the refrigerant dripping amount is sufficiently adjusted. Can be distributed.

  The remaining effects of the second embodiment are similar to those of the aforementioned first embodiment.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive.

However, the present invention is not limited to this. In the present invention, the number of holes in the primary chamber may be different from the number of rooms in the secondary chamber. At this time, the number of holes in the primary chamber must be larger than the number of rooms in the secondary chamber.

  Moreover, in the said 2nd Embodiment, although the heat exchange part 233 was formed so that it might extend in a Y direction, it showed the example comprised so that it might consist of the three heat exchanger tubes 233b which have the return structure laminated | stacked in the Z direction. The present invention is not limited to this. For example, the heat exchange unit may be configured by alternately stacking a plurality of heat transfer tubes extending in the Y direction and a plurality of heat transfer tubes extending in the X direction in the Z direction. In addition, the heat exchange part may be formed to extend in the Z direction, and may include a plurality of heat transfer tubes having a folded structure stacked in the X direction.

Although an example of application is shown, the present invention is not limited to this. In the present invention, the “liquid distributor” of the present invention may be used for an absorption heat pump apparatus other than a vehicle, or may be used for other than an absorption heat pump apparatus.
