Description

The present invention relates to a support member and a storage box.

In facilities such as communication facilities and data centers, electrical equipment such as servers are housed in racks for use. For example, Patent Document 1 discloses a rack with blanking panels that block off the parts of the rack where no servers are installed, preventing the server intake temperature from rising.

Patent No. 6149264

However, depending on the shape and type of the blanking panel, air heated by electrical equipment inside a storage box such as a rack may return to the area near the air intake of the electrical equipment, making it difficult to improve the cooling performance of the electrical equipment.

The present invention was made in consideration of these circumstances, and provides a support member and a storage box that can improve the cooling performance of electrical equipment.

(1) A support member according to one aspect of the present invention is used as a part of a storage box in which an electrical device is stored.

(Embodiment)
<1. Overall configuration of the rack>
1 is a perspective view showing a rack 1 and electrical equipment 2. The rack 1 is a structure in which the electrical equipment 2 is housed. The rack 1 is installed in a facility such as a communication facility or a data center. The rack 1 is an example of a "housing box."

The rack 1 accommodates, for example, a plurality of electrical devices 2. The plurality of electrical devices 2 are arranged, for example, vertically in the rack 1. The electrical devices 2 are, for example, information processing devices such as ICT (Information and Communication Technology) devices. Examples of ICT devices include, but are not limited to, server devices, network devices, and switch devices. Furthermore, the electrical devices 2 accommodated in the rack 1 are not limited to information and communication devices, and may be power supplies or other electrical devices.

As shown in FIG. 1, the rack 1 includes, for example, a housing 10, a main frame structure 20 (see FIG. 2), left and right mounting angles 30A and 30B, and a number of blanking panels 91 (see FIG. 5).

<1.1 Housing>
The housing 10 is a box member that forms the outer shell of the rack 1. The housing 10 has, for example, a housing main body 10a and a front door 10b. The housing main body 10a has, for example, a bottom plate 11, a ceiling plate 12, a left side plate 13, a right side plate 14, and a rear plate 15.

The bottom plate 11 is a horizontal plate that forms the bottom of the housing 10. The ceiling plate 12 is disposed above the bottom plate 11. The ceiling plate 12 is a horizontal plate that forms the ceiling of the housing 10.

The left side plate 13 extends vertically between the left end of the bottom plate 11 and the left end of the ceiling plate 12, connecting the left end of the bottom plate 11 and the left end of the ceiling plate 12. The left side plate 13 is a plate that runs along the depth direction and the vertical direction. The right side plate 14 extends vertically between the right end of the bottom plate 11 and the right end of the ceiling plate 12, connecting the right end of the bottom plate 11 and the right end of the ceiling plate 12. The right side plate 14 is a plate that runs along the depth direction and the vertical direction.

The rear plate 15 extends vertically between the rear end of the bottom plate 11 and the rear end of the ceiling plate 12, connecting the rear end of the bottom plate 11 and the rear end of the ceiling plate 12. The rear plate 15 is a plate portion that extends in the left-right and vertical directions. The rear plate 15 has multiple exhaust holes 10hb (see FIG. 3). The exhaust holes 10hb are through-holes that penetrate the rear plate 15. Note that the exhaust holes 10hb may be provided in the ceiling plate 12 instead of/in addition to the rear plate 15.

In this embodiment, the housing body 10a is formed in a box shape with an opening O on the front side. The opening O is larger than the outer shape of the electrical device 2 described below, and the electrical device 2 can be inserted into the opening O. The electrical device 2 is accommodated inside the housing 10 through the opening O.

The front door 10b is formed by a front plate 16 that is rotatably connected to the housing body 10a. The front plate 16 closes the opening O in an openable and closable manner. The front plate 16 has multiple air intake holes 10ha. The multiple air intake holes 10ha are provided, for example, at most of the height of the front plate 16.

In addition, the housing 10 may have a front plate 16 that can be attached to and detached from the housing main body 10a, instead of the pivoting front door 10b. Also, the housing 10 does not have to have the front door 10b (front plate 16). In this case, the housing 10 may be formed only by the housing main body 10a.

<1.2 Main frame structure>
Fig. 2 is a cross-sectional view showing the rack 1. For ease of explanation, screws 82 for attaching the electrical equipment 2 are omitted from Fig. 2.

The main frame structure 20 is a structure made of rigid members that increase the strength of the rack 1. The main frame structure 20 is provided, for example, inside the housing 10. The main frame structure 20 has, for example, a left main frame 21A, a right main frame 21B, and an upper main frame 22.

The left main frame 21A and the right main frame 21B are a pair of support members provided inside the housing 10. The left main frame 21A and the right main frame 21B are disposed on the rear side of the opening O and are spaced apart from each other in the left-right direction. Each of the left main frame 21A and the right main frame 21B is an example of a "rigid member." Each of the left main frame 21A and the right main frame 21B has a higher rigidity than, for example, the left side plate 13 or the right side plate 14.

In this embodiment, the left main frame 21A is disposed at the left front part of the housing 10 away from the left side plate 13 and extends vertically (see FIG. 3). The left main frame 21A extends vertically, for example, across the entire height of the housing 10. On the other hand, the right main frame 21B is disposed at the right front part of the housing 10 away from the right side plate 14 and extends vertically (see FIG. 3). The right main frame 21B extends vertically, for example, across the entire height of the housing 10.

In addition, instead of the above example, the left main frame 21A and the right main frame 21B may be provided integrally with the housing 10. For example, the left main frame 21A may be provided integrally with the left side plate 13. Also, the right main frame 21B may be provided integrally with the right side plate 14.

The upper main frame 22 is a beam member provided within the housing 10. The upper main frame 22 extends horizontally across the upper end of the left main frame 21A and the upper end of the right main frame 21B, connecting the upper end of the left main frame 21A and the upper end of the right main frame 21B. Note that instead of the above example, the upper main frame 22 may be provided integrally with the housing 10. For example, the upper main frame 22 may be provided integrally with the ceiling panel 12.

In addition to the left main frame 21A, right main frame 21B, and upper main frame 22 described above, the main frame structure 20 may also have a reinforcing structure at the rear of the housing 10 that is similar to or different from the left main frame 21A, right main frame 21B, and upper main frame 22.

<1.3 Mount angle>
Next, the left and right mounting angles 30A, 30B will be described. The left and right mounting angles 30A, 30B are a pair of members provided inside the housing 10. The left and right mounting angles 30A, 30B are disposed on the rear side of the opening O and are spaced apart from each other in the left-right direction. In the following, when there is no need to distinguish between the left mounting angle 30A and the right mounting angle 30B, they will be simply referred to as "mounting angles 30." The mounting angle 30 is a member that allows the electrical device 2 to be mounted at any height position. The mounting angle 30 is an example of a "support member."

The left mounting angle 30A is fixed to the left main frame 21A. The left mounting angle 30A is located in the left front part of the housing 10 and extends vertically (see FIG. 3). The left mounting angle 30A extends vertically, for example, across the entire height of the housing 10. On the other hand, the right mounting angle 30B is fixed to the right main frame 21B. The right mounting angle 30B is located in the right front part of the housing 10 and extends vertically (see FIG. 3). The right mounting angle 30A extends vertically, for example, across the entire height of the housing 10.

The mount angle 30 has, for example, multiple mounting holes 30h and multiple mounting holes 30hs. The multiple mounting holes 30hs will be described later.

The multiple mounting holes 30h are mounting holes for fixing the electrical device 2. The multiple mounting holes 30h are arranged in a line in one direction (e.g., vertically) on the mount angle 30. For example, the multiple mounting holes 30h are arranged in a line at equal intervals in one direction on the mount angle 30. Each mounting hole 30h is a through hole provided in the mount angle 30. Each mounting hole 30h may be a round hole, a square hole, or another shape. The shape and spacing of each mounting hole 30h conform to, for example, JIS (Japanese Industrial Standards) standards or EIA (Electronic Industries Alliance) standards.

A space is formed between the left mounting angle 30A and the right mounting angle 30B to accommodate the electrical device 2. The electrical device 2 is mounted in one or more (e.g., two) mounting holes 30h arbitrarily selected from the multiple mounting holes 30h. In this application, "mounted in a mounting hole" is not limited to mounting in the mounting hole itself, but may also include mounting in a mounting member (such as a cage nut) that is attached to the mounting hole. The multiple electrical devices 2 are fixed using the mounting holes 30h, so that two electrical devices 2 adjacent to each other in the vertical direction are stacked with no substantial gap between them.

FIG. 3 is a cross-sectional view of the rack 1 taken along line F3-F3 in FIG.
For ease of explanation, the configuration of the electric device 2 will be described below. The electric device 2 has, for example, a main body 51 and a pair of protruding parts 52A and 52B. The electric device 2 is accommodated in the housing 10 through the opening O with the main body 51 facing the rear and the protruding parts 52A and 52B facing the front.

The main body 51 is formed in a flat rectangular parallelepiped shape. The main body 51 includes, for example, a main body case 61 that forms the outer shell of the main body 51, various components 62 housed in the main body case 61, and a cooling fan 63 housed in the main body case. The front end 51e1 of the main body 51 is disposed so as to face the opening O of the housing 10. The front end 51e1 of the main body 51 has multiple intake holes 2ha. Meanwhile, the rear end 51e2 of the main body 51 is disposed so as to face the rear plate 15 of the housing 10. The rear end 51e2 of the main body 51 has multiple exhaust holes 2hb.

When the cooling fan 63 is driven, air outside the rack 1 moves to the front of the electrical device 2 through the intake hole 10ha of the front plate 16 of the housing 10, and flows into the interior of the electrical device 2 through the intake hole 2ha of the front end 51e1 of the main body 51. The air that flows into the interior of the electrical device 2 absorbs some of the heat generated by the components 62 included in the electrical device 2 as it passes through the interior of the electrical device 2, and is exhausted into the interior of the housing 10 through the exhaust hole 2hb of the rear end 51e2 of the main body 51. The air exhausted into the interior of the housing 10 is exhausted to the outside of the housing 10 through the exhaust hole 10hb of the housing 10. This promotes heat dissipation from the electrical device 2. Note that the electrical device 2 is not limited to a device that includes the cooling fan 63, and may be one that dissipates heat from the electrical device 2 into the interior of the housing 10 by heat dissipation from the surface of the main body 51.

The pair of protruding portions 52A, 52B are mounting portions for mounting the electrical device 2 to the mounting angle 30. The pair of protruding portions 52A, 52B are provided on the front end portion 51e1 of the main body portion 51.

One of the projections, 52A, projects leftward from the left end of the front end 51e1 of the main body 51, which is one side in the width direction of the main body 51. The projection 52A is formed in a plate shape that extends in the left-right and vertical directions. The projection 52A has a screw insertion hole 52h for mounting to the left mounting angle 30A (see FIG. 4). The screw insertion hole 52h is a through hole that passes through the projection 52A in the front-rear direction and faces the mounting hole 30h of the left mounting angle 30A.

The other overhanging portion 52B overhangs to the right, which is the other side in the width direction of the main body 51, from the right end of the front end portion 51e1 of the main body 51. The overhanging portion 52B is formed in a plate shape that extends in the left-right and vertical directions. The overhanging portion 52B has a screw insertion hole 52h for mounting to the right mounting angle 30B. The screw insertion hole 52h is a through hole that passes through the overhanging portion 52B in the front-rear direction and faces the mounting hole 30h of the right mounting angle 30B.

From another perspective, in this embodiment, the electrical device 2 has a case 71 with an open front side, and a front panel 72 attached to the front side of the case 71. The width dimension W2 of the front panel 72 is greater than the width dimension W1 of the case 71. As a result, a portion of the front panel 72 protrudes leftward beyond the left side surface of the case 71, forming the above-mentioned protrusion 52A. In addition, another portion of the front panel 72 protrudes rightward beyond the right side surface of the case 71, forming the above-mentioned protrusion 72B.

The electrical device 2 is not limited to a device having a front panel 72. For example, the electrical device 2 may have a case 71 and protruding portions 52A, 52B formed by bending a portion of the case 71, and the inside of the case 71 may be exposed to the front.

Next, the mount angles 30A and 30B will be described in detail.
FIG. 4 is an enlarged cross-sectional view showing the periphery of the mount angles 30A and 30B.
First, the left mounting angle 30A will be described. The left mounting angle 30A has, for example, a fixing portion 35 and a support portion 36.

The fixing part 35 is a part that fixes the left mounting angle 30A to the left main frame 21A. The fixing part 35 is plate-shaped along the depth direction and the vertical direction. The fixing part 35 extends vertically so as to span the entire height of the mounting angle 30. The fixing part 35 has a screw insertion hole 35h that penetrates the fixing part 35 in the left-right direction. The left main frame 21A has a screw hole 21h that communicates with the screw insertion hole 35h of the fixing part 35. The screw 81 passed through the screw insertion hole 35h of the fixing part 35 engages with the screw hole 21h of the left main frame 21A, thereby fixing the fixing part 35 to the right side surface of the left main frame 21A.

The support portion 36 has, for example, a first portion 41 , a second portion 42 , and a third portion 43 .
The first portion 41 bends and extends to the right from the front end of the fixing portion 35. That is, the first portion 41 extends from the front end of the fixing portion 35 toward the main body 51 of the electric device 2. The first portion 41 is plate-shaped along the left-right and vertical directions. The first portion 41 extends in the vertical direction so as to cover the entire height of the mounting angle 30. The first portion 41 is not provided with the mounting hole 30h and the mounting hole 30hs. That is, the first portion 41 is not provided with an opening.

The second part 42 is bent (for example, bent 90°) from the right end of the first part 41 and extends forward. That is, the second part 42 extends from the right end of the first part 41 toward the opening O of the housing 10. The second part 42 is a plate shape along the depth direction and the vertical direction. The second part 42 extends vertically so as to cover the entire height of the mount angle 30. The second part 42 is along the left side surface of the main body 51 of the electrical device 2. In this embodiment, the gap between the second part 42 and the main body 51 of the electrical device 2 is small, for example, substantially zero. For example, the gap between the second part 42 and the main body 51 of the electrical device 2 is smaller than the plate thickness t of the second part 42. The second part 42 does not have the mounting hole 30h and the mounting hole 30hs. That is, the second part 42 does not have an opening.

The third portion 43 is bent (e.g., bent 90°) from the front end of the second portion 42 and extends to the left. That is, the third portion 43 extends from the front end of the second portion 42 in a direction away from the main body 51 of the electrical device 2. The third portion 43 is a plate-like shape that extends in the left-right and vertical directions. The third portion 43 is, for example, parallel to the first portion 41. The third portion 43 extends in the vertical direction so as to span the entire height of the mounting angle 30. The third portion 43 faces the opening side of the housing 10. When the electrical device 2 is attached to the mounting angle 30, the third portion 43 extends along the rear surface (back surface) of the protruding portion 52A of the electrical device 2. The third portion 43 is provided with a plurality of mounting holes 30h and a plurality of mounting holes 30hs (see FIG. 2).

The protruding portion 52A of the electrical device 2 is attached to the third portion 43. For example, the mounting member 85 is attached to the mounting hole 30h of the third portion 43 from the rear side of the third portion 43. The mounting member 85 is, for example, a cage nut. The mounting member 85 includes an engagement portion 85a that is inserted into the mounting hole 30h and engages with the mounting hole 30h, and a screw hole 85h that opens toward the front of the third portion 43. The electrical device 2 is arranged so that the screw insertion hole 52h of the protruding portion 52A is aligned with the screw hole 85h of the mounting member 85, and the screw 82 is inserted into the screw insertion hole 52h of the protruding portion 52A from the front of the third portion 43, and the screw 82 engages with the screw hole 85h of the mounting member 85, thereby mounting the electrical device 2 to the third portion 43 of the support portion 36. As a result, the protruding portion 52A of the electrical device 2 is attached to one or more (e.g., two) mounting holes 30h arbitrarily selected from the multiple mounting holes 30h.

In addition, instead of the above example, the mounting hole 30h may be a screw hole into which the screw 82 directly engages, or a screw insertion hole through which the screw 82 passes. In this application, the "mounting hole" may be any hole used to fix the electrical device 2.

As shown in FIG. 4, the space S between the first portion 41 and the third portion 43 (the space S located behind the third portion 43) communicates with the opening O only through a region (first region S1 described below) located on the opening O side of the first portion 41 within the housing 10. The space S located behind the third portion 43 is not connected to the second region S2 described below. In other words, the spaces before and after the attachment hole 30h are integrated with the space on the front side of the mounting angle 30A.

Next, the right mount angle 30B will be described. The right mount angle 30B has a shape that is a mirror image of the left mount angle 30A. Therefore, the description of the right mount angle 30B can be achieved by reversing the left and right in the above description of the left mount angle 30A, reading "left mount angle 30A" as "right mount angle 30B," and reading "extension 52A" as "extension 52B."

In addition to the left and right mounting angles 30A and 30B described above, another mounting angle that supports the rear end of the electrical device 2 may be provided inside the housing 10, and a support angle that supports the side end of the electrical device 2 may be provided.

Next, we will explain the multiple areas (first area S1 and second area S2) formed within the housing 10 by the electrical device 2 and the left and right mounting angles 30A, 30B, etc.

The first area (first space) S1 is a cold air area into which cold air flows in from the outside through the opening O of the housing 10. In this application, "cold air" means air before it is heated by the electrical device 2, for example, air at room temperature. The first area S1 is defined by, for example, the front surface of the left main frame 21A, the front surface of the first part 41 of the left mounting angle 30A, the left side surface of the second part 42 of the left mounting angle 30A, the front surface of the electrical device 2, the front surface of the right main frame 21B, the front surface of the first part 41 of the right mounting angle 30B, and the right side surface of the second part 42 of the right mounting angle 30B. The first area S1 is an area in the housing 10 that is not hatched with dots in Figures 3 and 4. The multiple air intake holes 2ha of the electrical device 2 open into the first area S1. Cold air flows into the electrical device 2 from the first area S1 through the multiple air intake holes 2ha.

On the other hand, the second region (second space) S2 is a warm air region where the air heated by the electric device 2 is located. The second region S2 is, for example, a region behind the first portion 41 of the left and right mounting angles 30A, 30B. Here, in this embodiment, the gap between the second portion 42 of the left and right mounting angles 30A, 30B and the left and right side surfaces of the main body 51 of the electric device 2 is negligibly small (for example, smaller than the plate thickness t of the second portion 42). In this case, the second region S2 is defined by the rear surface of the first portion 41 of the left and right mounting angles 30A, 30B and the left and right side surfaces of the main body 51 of the electric device 2. Note that, when the gap between the second portion 42 of the left and right mounting angles 30A, 30B and the left and right side surfaces of the main body 51 of the electric device 2 is large, the second region S2 may include the region between the second portion 42 of the left and right mounting angles 30A, 30B and the left and right side surfaces of the main body 51 of the electric device 2. The second area S2 is the area hatched with dots in the housing 10 in Figures 3 and 4. The multiple exhaust holes 2hb of the electrical device 2 open into the second area S2. Air that is warmed by passing through the interior of the electrical device 2 is exhausted from the multiple exhaust holes 2hb of the electrical device 2 to the second area S2.

<1.4 Blank Panel>
Next, the concealing panel 91 will be described.
Fig. 5 is a cross-sectional view showing the rack 1 and the electric device 2 in a state where the concealing panel 91 is attached. For convenience of explanation, the screws 82 for attaching the electric device 2 and the concealing panel 91 are omitted in Fig. 5.

The blanking panel 91 is a member that assists in dividing the inside of the housing 10 into a first region S1 and a second region S2, and is disposed in the height region of the non-mounted portion of the electrical device 2. The blanking panel 91 has screw insertion holes 91h similar to the screw insertion holes 52h of the electrical device 2, and is attached to the left and right mounting angles 30A, 30B with screws 82 in the height region of the non-mounted portion of the electrical device 2, similar to the electrical device 2. This forms a wall portion that divides the first region S1 and the second region S2 in the height region of the non-mounted portion of the electrical device 2. As a result, the warm air in the second region S2 is prevented from returning to the first region S1 through the height region of the non-mounted portion of the electrical device 2.

However, some concealing panels 91 have a shape that does not cover some of the mounting holes 30h. An example of such a concealing panel 91 is described below.

6 is a perspective view showing an example of a concealing panel 91. The concealing panel 91 shown in FIG. 6 has openings 91a in the portions corresponding to some of the mounting holes 30h. The openings 91a are provided so that, for example, when the stiffness of the concealing panel 91 alone is insufficient, the reinforcing panel 92 can be additionally attached to the mounting angles 30A and 30B by overlapping with the concealing panel 91. The reinforcing panel 92 has screw insertion holes 92h similar to the screw insertion holes 52h of the electrical device 2. The screw insertion holes 92h face the mounting holes 30h of the mounting angles 30A and 30B through the openings 91a of the concealing panel 91. The reinforcing panel 92 is attached to the left and right mounting angles 30A and 30B by the screws 82, similar to the electrical device 2. However, the reason why the concealing panel 91 has a shape that does not cover some of the mounting holes 30h is not limited to the above example, and may be for another reason.

When such a concealing panel 91 that does not cover some of the mounting holes 30h is attached to the mounting angles 30A, 30B (for example, when the stiffness of the concealing panel 91 alone is not an issue and the reinforcing panel 92 is omitted), some of the mounting holes 30h are not blocked when the electrical device 2 is attached to the mounting angles 30A, 30B, and these mounting holes 30h remain in a state where air can pass through. The phenomenon that occurs in this case will be described later.

<1.5 Side blanking panel>
Next, the side concealing panels 95 will be described.
As shown in Fig. 4, the third portion 43 of the support portion 36 of the mount angle 30 has a plurality of mounting holes 30hs (only one is shown in Fig. 4). In the left mount angle 30A, the mounting hole 30hs is disposed to the left of the mounting hole 30h. In the right mount angle 30B, the mounting hole 30hs is disposed to the right of the mounting hole 30h.

2, the multiple mounting holes 30hs are arranged vertically. Side blanking panels 95 are attached to the multiple mounting holes 30hs, for example, by screws (not shown). The side blanking panels 95 are panels arranged on the sides of the electrical appliance 2 and the blanking panel 91 to further prevent the air warmed by the electrical appliance 2 from returning to the front side of the electrical appliance 2. For example, the side blanking panels 95 are arranged between the electrical appliance 2 and the left side plate 13, and between the electrical appliance 2 and the right side plate 14 (see FIG. 3). Similarly, the side blanking panels 95 are arranged between the blanking panel 91 and the left side plate 13, and between the blanking panel 91 and the right side plate 14. The side blanking panels 95 may be omitted.

<1.6 Ventilation restriction members>
Next, the ventilation restriction member M will be described.
The rack 1 has a ventilation restriction member M that restricts air from moving from the second area S2 to the first area S1 within the rack 1. The ventilation restriction member M is disposed, for example, between the left main frame 21A and the left side plate 13, or between the right main frame 21B and the right side plate 14, and extends vertically. If there are gaps between the left main frame 21A and the left side plate 13 and between the right main frame 21B and the right side plate 14, the ventilation restriction member M closes the gaps. In other words, the ventilation restriction member M is a member that is a part of the partition that separates the first area S1 and the second area S2. When the ventilation restriction member M is provided, the warm air in the second area S2 is prevented from moving to the space behind the third part 43 of the support part 36 of the mounting angles 30A and 30B. In this embodiment, when the ventilation restriction member M is provided, the side blanking panel 95 is omitted.

<2. Effect＞
FIG. 7 is a diagram for explaining the operation of the left and right mounting angles 30 of this embodiment.
Fig. 7(a) shows an L-shaped mount angle 100 as a comparative example, and Fig. 7(b) shows mount angles 30A and 30B of this embodiment.

The L-shaped mounting angle 100 of the comparative example shown in FIG. 7(a) has a first portion 101 extending forward from a fixing portion 35 fixed to the left and right main frames 21A, 21B, and a second portion 102 bent from the front end of the first portion 101. The second portion 102 has a screw insertion hole 30h, and the protruding portions 52A, 52B of the electrical device 2 are attached to the second portion 102.

In this configuration, the space behind the second portion 102 where the screw insertion holes 30h are open becomes part of the second region S2, and air warmed by the electrical device 2 is present. In this configuration, if a concealing panel 91 that does not cover some of the mounting holes 30h of the mounting angle 100 is attached, the warm air in the second region S2 will leak out into the first region S1 through the mounting holes 30h of the mounting angle 100 that are not covered by the concealing panel 91. As a result, the cool air in the first region S1 is heated, and there is a possibility that the warm air will flow into the interior of the electrical device 2 through the air intake holes 2ha of the electrical device 2. In this case, it becomes difficult to promote cooling of the electrical device 2.

In addition, when the mounting hole 30hs is provided in the second portion 102 of the mounting angle 100, even when the ventilation restriction member M is attached, the warm air in the second area S2 leaks out through the mounting hole 30hs into the first area S1. From this perspective as well, it becomes difficult to promote cooling of the electrical device 2.

On the other hand, as shown in FIG. 7B, in the mount angle 30 of this embodiment, the space S located behind the third portion 43 where the mounting hole 30h is open becomes part of the first region S1, and cold air is present therein. Therefore, even if a concealing panel 91 that does not cover some of the mounting holes 30h of the mount angles 30A and 30B is attached, the warm air in the second region S2 is prevented from leaking into the first region S1 through the mounting holes 30h of the mount angles 30A and 30B that are not covered by the concealing panel 91. As a result, compared to the configuration of the comparative example, cold air is more likely to flow into the interior of the electric device 2 from the air intake hole 2ha of the electric device 2. This promotes cooling of the electric device 2.

Even if the mounting hole 30hs is provided in the third portion 43 of the mounting angle 30, if the ventilation restriction member M is provided, the warm air in the second area S2 is prevented from leaking into the first area S1 through the mounting hole 30hs. This also promotes cooling of the electrical device 2.

3. Advantages
In this embodiment, the mount angle 30 has a fixing portion 35 fixed to the left main frame 21A (or the right main frame 21B), and a support portion 36 in which a plurality of mounting holes 30h are arranged in one direction and in which the protruding portion 52A (or the protruding portion 52B) of the electric device 2 can be attached to one or more mounting holes 30h arbitrarily selected from the plurality of mounting holes 30h. The support portion 36 has a first portion 41 extending from the fixing portion 35 toward the main body portion 51 of the electric device 2, a second portion 42 bending from an end of the first portion 41 and extending toward the opening O, and a third portion 43 bending from an end of the second portion 42 and extending in a direction away from the main body portion 51 of the electric device 2, having a plurality of mounting holes 30h, and in which the protruding portion 52A (or the protruding portion 52B) of the electric device 2 is attached. According to this configuration, even if there are mounting holes 30h in the mounting angles 30A, 30B that are not covered by the concealing panel 91, it is possible to prevent the warm air in the second area S2 from leaking through the mounting holes 30h to the front side of the electric device 2. This can promote cooling of the electric device 2, thereby improving the cooling performance of the electric device 2.

In this embodiment, the second portion 42 of the support portion 36 fits along the side surface of the main body portion 51 of the electrical device 2. With this configuration, when the electrical device 2 is inserted into the housing 10, the second portion 42 of the support portion 36 can be used as a guide to guide the electrical device 2 toward the depth direction of the housing 10. This can improve the ease of installation of the electrical device 2.

In this embodiment, the third portion 43 of the support portion 36 is aligned with the rear surface of the protruding portion 52A (or the protruding portion 52B) of the electrical device 2. With this configuration, the gap between the third portion 43 of the support portion 36 and the protruding portion 52A (or the protruding portion 52B) of the electrical device 2 can be reduced (e.g., reduced to zero). This further prevents the warm air in the second area S2 from leaking to the front side of the electrical device 2.

In this embodiment, the third portion 43 of the support portion 36 is exposed to the opening O side of the housing 10. This configuration prevents the warm air in the second area S2 from leaking to the front side of the electrical device 2, and improves the ease of mounting the electrical device 2 to the mounting angle 30.

The support member and storage box of one embodiment have been described above. However, the configuration of the embodiment is not limited to the above example. The "storage box" referred to in this application is not limited to a rack in which the electrical devices 2 are stacked vertically, but may be a storage box in which the electrical devices 2 are arranged horizontally (i.e., a storage box in which the mounting holes are arranged horizontally).
