Embodiment 1

[0059] [Example 1] --- Figures 1 and 2

[0060] In Embodiment 1 of the present invention, as shown in FIGS. 1 and 2, the partial offset between the outdoor heat exchanger 12 for the air conditioner and the heat exchanger 11 for cooling the fuel cell is achieved by placing the outdoor heat exchanger 12 for the air conditioner in the vehicle. This is achieved by partially offsetting the fuel cell cooling heat exchanger 11 in the right and left direction. In Embodiment 1 of the present invention, the fan guard 17 does not need to be provided.

[0061] According to the effects and technical advantages of Embodiment 1 of the present invention, since the width of the front compartment of the vehicle is greater than the height of the vehicle, it is easy to realize the outdoor heat exchanger 12 for the air conditioner and the heat exchanger 11 for cooling the fuel cell in the right and left direction of the vehicle bias.

Embodiment 2

[0062] [Example 2] --- Figure 3

[0063] In Embodiment 2 of the present invention, as shown in FIG. 3, the partial offset between the outdoor heat exchanger 12 for the air conditioner and the heat exchanger 11 for cooling the fuel cell is achieved by placing the outdoor heat exchanger 12 for the air conditioner on the right and left sides of the vehicle. This is achieved by partially offsetting the fuel cell cooling heat exchanger 11 from one another in the direction. In Embodiment 2 of the present invention, it is necessary to provide a fan guard 17 .

[0064] In a front view, a portion 11a of the fuel cell cooling heat exchanger 11 extending from the end of the air conditioner outdoor heat exchanger 12 facing the high temperature portion 12a extends from the fan guard 17 in the right and left direction of the vehicle. out.

[0065] According to the effects and technical advantages of Embodiment 2 of the present invention, due to the part 11a of the fuel cell cooling heat e...

Embodiment 3

[0066] [Embodiment 3] --- Figures 4 and 5

[0067] In Embodiment 3 of the present invention, as shown in FIGS. 4 and 5, the partial offset between the outdoor heat exchanger 12 for the air conditioner and the heat exchanger 11 for cooling the fuel cell is achieved by making the outdoor heat exchanger 12 for the air conditioner in the vehicle This is achieved by partially offsetting the fuel cell cooling heat exchanger 11 from each other in the up and down (vertical) direction. The portion 11a of the fuel cell cooling heat exchanger 11 extending from the end of the air conditioner outdoor heat exchanger 12 opposite to the high temperature portion 12a in front view extends from the fan shroud 17 in the downward direction and from the An end portion of the air conditioner outdoor heat exchanger 12 facing the high temperature portion 12a extends. The vehicle running wind flowing through the air inlet 18 located under the bumper directly contacts the part 11a.

Abstract

The present invention provides a cooling apparatus of a fuel cell vehicle in which a cooling efficiency of a fuel cell cooling heat exchanger located downstream of an air conditioner external heat exchanger does not decrease. (1) In the cooling apparatus, the air conditioner external heat exchanger and the fuel cell cooling heat exchanger are partially offset from each other so that a high-temperature portion of the air conditioner external heat exchanger is not overlapped with the fuel cell cooling heat exchanger in a front view taken from a front side of the vehicle. (2) A portion of the fuel cell cooling heat exchanger extending beyond an end of the air conditioner exterior heat exchanger opposite the high-temperature portion is disposed outside a fan shroud so as to be cooled by a vehicle-running wind only.

Description

technical field [0001] The invention relates to a cooling device for a vehicle. Background technique [0002] Japanese Patent Publication No. 2003-118396 discloses a fuel cell vehicle cooling device including an outdoor (external) heat exchanger for an air conditioner and a heat exchanger for fuel cell cooling. [0003] As shown in FIG. 6, in this device, an outdoor heat exchanger 2 for an air conditioner and a heat exchanger 1 for cooling a fuel cell are arranged in sequence from upstream to downstream along the flow direction of air flowing through the heat exchanger. The outdoor heat exchanger 2 for the air conditioner is arranged in front of the heat exchanger 1 for cooling the fuel cell so that the entire part of the outdoor heat exchanger 2 for the air conditioner is in contact with the fuel cell in the front view of the heat exchanger when viewed from the front of the vehicle. The heat exchanger 1 for battery cooling is overlapped. [0004] FIG. 6 also shows that th...
