Description

The present invention relates to a vehicle structure, and more particularly to a vehicle structure in which air whose temperature has risen by a condenser is supplied to a radiator.

In front of the vehicle in the engine room, capacitors and radiators are arranged in this order with respect to the flow direction of the running wind. The traveling wind, which is arranged in front of the vehicle and flows in from the opening communicating with the engine room, passes through the respective cores of the condenser and the radiator arranged in this way, and heat exchange is performed. However, when the hot air generated by the heat exchange is rewound to the front of the engine room and passes through (recirculates) the cores of the condenser and the radiator again, the amount of cooling heat of the condenser and the radiator decreases. Therefore, in Patent Document 1, the space between the condenser and the radiator is covered with an air guide member.

If the size of the radiator core is larger than the size of the condenser core, a part of the running wind is supplied to the radiator core without passing through the condenser core. However, when the air guide member is arranged as in Patent Document 1, a part of the traveling wind is not supplied to the radiator core, which causes a problem that the cooling heat amount of the radiator is reduced.

Therefore, a main object of the present invention is to provide a vehicle structure capable of reducing the concern that the amount of cooling heat of the radiator is reduced.

The vehicle structure according to the present invention includes a condenser for a vehicle having a condenser frame, a radiator for a vehicle arranged behind the condenser so that the peripheral edge of the radiator core is hidden by the condenser frame when viewed from the front of the vehicle, and a condenser and a radiator. at least a portion and a shielding member which shields the vehicle viewed or vehicle side view, is arranged in a space, the capacitor the air passing through the condenser, at the peripheral portion of the radiator core, in the vehicle front view of the space between the It is equipped with a guide member that guides to a part hidden by the frame, and the guide member is aligned so that one end is slightly below the upper end of the capacitor core whose outer edge is surrounded by the capacitor frame, and the other end is the capacitor of the radiator core. It is adjusted to a position slightly below the lower end of the portion hidden by the frame, and the angle formed by the main surface of the guiding member with respect to the direction perpendicular to the main surface of the capacitor is 10 ° or less.

By providing a shielding member that shields at least a part of the space between the condenser and the radiator from the top view of the vehicle or the side view of the vehicle, the recirculation of the air that has passed through the condenser and the radiator is suppressed. In addition, where the peripheral edge of the radiator core is hidden by the condenser frame when viewed from the front of the vehicle, the radiator is cooled by arranging an induction member that guides the air that has passed through the condenser to the peripheral edge in the space between the condenser and the radiator. The concern that the amount of heat will decrease is reduced.

The above-mentioned object, other object, feature and advantage of the present invention will be further clarified from the detailed description of the following examples made with reference to the drawings.

It is a schematic diagram which shows the state which the vehicle structure of another Example was viewed from the front.

With reference to FIGS. 1, 2 (A) and 2 (B), the vehicle structure 10 of this embodiment includes a capacitor 12 for a vehicle and a radiator 14 arranged behind the capacitor 12. ..

The capacitor 12 is composed of a rectangular plate-shaped capacitor core 12c whose main surface is a long side in the left-right direction of the vehicle, and a metal capacitor frame 12f that surrounds the outer edge of the capacitor core 12c and supports the capacitor core 12c. Will be done. Since the main surface of the capacitor core 12c is rectangular, the outer and inner edges of the capacitor frame 12f are also rectangular when viewed from a direction orthogonal to the main surface.

The radiator 14 is composed of a plate-shaped radiator core 14c having a rectangular main surface and a metal radiator frame 14f that surrounds the outer edge of the radiator core 14c and supports the radiator core 14c. Since the main surface of the radiator core 14c is rectangular, the outer and inner edges of the radiator frame 14f are also rectangular when viewed from a direction orthogonal to the main surface. A radiator fan 14w and a fan shroud 14s are arranged behind the radiator core 14c.

The wind generated by the running of the vehicle or the wind generated by the rotation of the radiator fan 14w is first heat-exchanged by the condenser core 12c and then heat-exchanged by the radiator 14c. As a result, the refrigerant flowing through the condenser core 12c or the cooling water flowing through the radiator core 14c is cooled.

However, the length of the short side of the rectangle formed by the main surface of the radiator core 14c exceeds the length of the short side of the rectangle formed by the outer edge of the capacitor frame 12f. Further, the condenser 12 and the radiator 14 are arranged so that the main surfaces of the condenser cores 12c and 14c face the front-rear direction of the vehicle, and the long sides of the rectangle formed by the main surfaces extend in the left-right direction of the vehicle. The center of the main surface of the condenser core 12c is positioned so as to overlap the center of the main surface of the radiator core 14c. As a result, when the vehicle structure 10 is viewed from the front, the upper end Ps (see FIG. 2A) of the radiator core 14c is hidden by the condenser frame 12f.

The shielding member (plate) 16 is made of resin or metal, and has a length corresponding to the long side of the rectangle formed by the outer edge of the capacitor frame 12f and a distance substantially the same as the distance from the back surface of the capacitor core 12c to the front surface of the radiator core 14c. It has a width corresponding to, and is formed in a band shape. The shielding member 16 is arranged above the space SP1 between the condenser 12 and the radiator 14 so that the band extends along the left-right direction of the vehicle.

At this time, both ends in the length direction of the band are aligned with both ends of the long side of the rectangle formed by the outer edge of the capacitor frame 12f. Further, one end in the width direction of the band is aligned with the upper end of the capacitor frame 12f, and the other end in the width direction of the band is aligned with the upper end of the radiator core 14c. As a result, the shielding member 16 shields at least a part of the space SP1 in a top view.

The guide member (louver) 18 is also made of resin or metal, and has a length corresponding to the long side of the rectangle formed by the outer edge of the condenser frame 12f and a distance substantially the same as the distance from the back surface of the condenser core 12c to the front surface of the radiator core 14c. It has a width corresponding to, and is formed in a band shape. The guide member 18 is arranged at a position slightly below the shielding member 16 in the space SP1 so that the band extends along the left-right direction of the vehicle.

At this time, both ends in the length direction of the band are aligned with both ends of the long side of the rectangle formed by the outer edge of the capacitor frame 12f. Further, one end in the width direction of the band is aligned with a position slightly lower than the upper end of the capacitor core 12c, and the other end in the width direction of the band is aligned with a position slightly lower than the lower end of the upper end Ps described above. Be done.

With reference to FIG. 2B, the angle formed by the main surface of the shielding member 16 with respect to the direction perpendicular to the main surface of the capacitor core 12c is θ1, and the main surface of the induction member 18 is the main surface of the capacitor core 12c. Assuming that the angle formed in the vertical direction is θ2, both the angles θ1 and θ2 exceed 0 °. Preferably, the maximum angle of the angle θ2 is 10 °.

As a result, a part of the wind that has passed through the condenser core 12c is guided by the guiding member 18 to the upper end Ps of the radiator core 14c. Further, by suppressing the angle θ2 to 10 ° or less, the concern that a vortex is generated on the lower side of the guiding member 18 is reduced. The concern that a vortex is generated can also be alleviated by bending the guiding member 18 so as to rise as it approaches the radiator 14.

According to this embodiment, by providing the shielding member 16 that shields at least a part of the space SP1 between the condenser 12 and the radiator 14 from the top view, the recirculation of the air that has passed through the condenser 12 and the radiator 14 is suppressed. Will be done. Further, where the upper end Ps of the radiator core 14c is hidden by the condenser frame 12f in front view, the guiding member 18 that guides the air passing through the condenser 12 to the upper end Ps is placed in the space SP1 between the condenser 12 and the radiator 14. By arranging the radiator 14, the concern that the amount of cooling heat of the radiator 14 is lowered is reduced.

With reference to FIGS. 3, 4 (A) and 4 (B), the vehicle structure 10 of the other embodiment is provided with the shielding member 20 in place of the shielding member 16 and the guiding member 18. Since it is the same as the vehicle structure 10 of the above-described embodiment, duplicate description regarding the same configuration will be omitted.

The shielding member 20 is made of resin or metal, and has a length corresponding to the long side of the rectangle formed by the outer edge of the capacitor frame 12f and a distance approximately twice the distance from the back surface of the capacitor core 12c to the front surface of the radiator core 14c. It has a corresponding width and is formed in a band shape. The shielding member 20 is arranged above the space SP1 between the condenser 12 and the radiator 14 so that the band extends along the left-right direction of the vehicle.

At this time, the upper surface of the band is substantially flush with the upper surface of the radiator frame 14f. Further, both ends in the length direction of the band are aligned with both ends of the long side of the rectangle formed by the outer edge of the radiator frame 14f. Further, one end in the width direction of the band is aligned with the position on the front side of the front end of the condenser frame 12f, and the other end in the width direction of the band is aligned with the position close to the front end of the radiator frame 14f. Therefore, the shielding member 20 also shields at least a part of the space SP1 in a top view.

At the other end of the band formed by the shielding member 20 in the width direction, cuts extending from the other end toward one end are made at substantially equal intervals in the length direction of the band. As a result, a plurality of strips 20s, 20s, ... Supported by the shielding member 20 are formed at the other end. The formed plurality of strips 20s, 20s, ... Are bent downward every other strip, and the folded strips 20s, 20s, ... Form the guiding member. Therefore, a part of the wind that has passed through the gap between the shielding member 20 and the condenser 12 is guided to the upper end portion Ps of the radiator core 14c by the strips 20s, 20s, ....

According to this embodiment, by providing the shielding member 20 that shields at least a part of the space SP1 between the condenser 12 and the radiator 14 from the top view, the recirculation of the air that has passed through the condenser 12 and the radiator 14 is suppressed. Will be done. Further, where the upper end Ps of the radiator core 14c is hidden by the condenser frame 12f in front view, the strips 20s, 20s, ... That guide the air passing through the gap between the shielding member 20 and the condenser 12 to the upper end Ps are connected to the condenser 12. By arranging it in the space SP1 between the radiator 14 and the radiator 14, the concern that the amount of cooling heat of the radiator 14 decreases can be reduced.

In this embodiment, the shielding member 20 having the shape shown in FIG. 4B is arranged above the space SP1. However, instead of this, the shielding member 20'in the shape shown in FIG. 5 may be arranged above the space SP1. According to FIG. 5, the other end (the end close to the radiator core 14c) in the width direction of the band formed by the shielding member 20'draws a wave when viewed from the front of the vehicle. By providing the shielding member 20'in this shape, a part of the wind that has passed through the gap between the shielding member 20 and the condenser 12 is guided to the upper end portion Ps of the radiator core 14c. As a result, the concern that the amount of cooling heat of the radiator 14 is reduced is reduced.

Further, in the above-described embodiment, the shielding member 16 or 20 is provided so as to shield at least a part of the space SP1 from the top view of the vehicle. However, another shielding member that shields at least a part of the space SP1 from the side view of the vehicle may be additionally or optionally provided.

In the above-mentioned induction member, when a plate fin type heat exchanger such as the radiator 14 is viewed from the front, at least a part of the heat exchange portion is some kind of member (for example, a modulator tank of a capacitor, an outside temperature sensor, etc.). When the flow of cooling air to the heat exchanger is obstructed by the member, the technical significance of suppressing the decrease in the amount of cooling heat of the heat exchanger is achieved.
