Problems solved by technology

However, there is a problem that a part of the air does not pass through when the engine is idling during parking or when driving at a very low speed because there is a gap in the front-rear direction of the vehicle between the cylindrical body in which the cooling fan is built-in and the heat exchanger. The heat exchanger is sucked into the cooling fan from its outer peripheral side through the above-mentioned gap, or a part of the air passes through the cooling fan and then turns back and is sucked into the cooling fan from the outer peripheral side of the cooling fan through the above-mentioned gap respectively. The cooling capacity of the heat exchanger reduce accordingly

Embodiment 1

[0029] First, the overall structure of Embodiment 1 will be described.

[0030] Such as figure 1 , figure 2 As shown, the heat exchanger of this embodiment 1 has a condenser 1 as a first heat exchanger, a radiator 2 as a second heat exchanger, a motor fan 3 as a blower, and a fan guard 4 supporting the motor fan 3 As the main structure, these components are integrally installed in the order of the condenser 1, the fan guard 4 supporting the motor fan 3, and the radiator 2 from the front side of the vehicle along the front and rear directions of the vehicle, and are supported by a radiator core not shown. Rods support these components on the body.

[0031] Such as image 3 As shown, the condenser 1 as the first heat exchanger is used as an air conditioner, and the condenser 1 includes a first heat exchange part (condenser core part) 11 capable of allowing air to circulate in the front and rear directions of the vehicle, respectively installed on the first The left side tan...

Embodiment 2

[0071] This embodiment 2 shows another example of the fan guard portion in the embodiment 1, Figure 4 It is a front view showing the fan guard part of the vehicle heat exchanger of the second embodiment.

[0072] In the vehicle heat exchanger according to the second embodiment, in the frame of the cylindrical portion 41 of the fan guard 4 , the portion around the circular ventilation hole 47 for guiding the blown air from the engine fan is blocked by the panel 48 . It is different from the above-mentioned Example 1. However, inside the cylindrical portion 41 of the fan guard 4 , both the upstream side and the downstream side of the panel 48 have the same size and shape as those of the first embodiment.

[0073] Therefore, in this Example 2, although the ventilation resistance at the fan guard 4 slightly increases in the effect (1) of the Example 1, in addition to the same effect as that of the Example 1, the following effects can be obtained.

[0074] (8) Since parts other ...

Embodiment 3

[0076] This Example 3 shows a modified example of the fan guard portion in Example 2, Figure 5 It is a front view showing the fan guard part of the vehicle heat exchanger of Example 3, Figure 6 yes Figure 5 An enlarged cross-sectional view of the S6-S6 line, Figure 7 It is a perspective view showing the main part of the third embodiment seen from the rear of the vehicle.

[0077] In the vehicle heat exchanger of Embodiment 3, communication holes 50 are provided at the four corners of the panel 48 of the motor fan 3 except for the ventilation hole 47, and the communication hole 50 has a check valve 49. 49 allows the flow from the condenser 1 side to the radiator 2 side, but prevents the reverse flow from the radiator 2 side to the condenser 1 side, which is different from the second embodiment described above.

[0078] That is, a ventilation hole 47 for guiding the air blowing of the motor fan 3 is provided at the substantially central portion of the panel 48 within the ...

Abstract

The present invention provides a vehicle heat exchanger that suppresses the ventilation resistance generated between first and second heat exchangers and makes one heat exchanger less likely to be affected by heat from the other heat exchanger. This vehicle heat exchanger has a first heat exchanger and a second heat exchanger arranged downstream thereof. A blower is arranged in the air passage of air formed in the space between these heat exchange parts, and a fan guard having a cylindrical portion covering the outer periphery of the blower and forming the air passage and a support for supporting the blower is provided part and a plurality of support struts extending from the support part to the cylindrical part and connecting the two.

Description

technical field [0001] The present invention relates to a heat exchanger for a vehicle that has a plurality of heat exchangers and cools refrigerant flowing through the heat exchangers with air blown by a cooling fan. Background technique [0002] The vehicle heat exchanger is configured by mounting one (for example, only a radiator for engine cooling) or a plurality of (for example, a radiator and a condenser of an air conditioner) heat exchangers to a vehicle for various purposes. In this case, in order to efficiently cool these heat exchangers in a wide range of engine operating regions from engine idling to high-speed running, it is important how to ensure the required cooling capacity. Therefore, conventionally, an arrangement or an installation method of a heat exchanger or a cooling fan has been studied as follows. [0003] As a conventional heat exchanger for a vehicle, two different heat exchangers, a radiator and a cooling condenser (cooler condenser), are known t...
