    摘要： 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.

    摘要： A FC radiator in a FC cooling system, an EV radiator in a driving device cooling system, and a condenser in an air conditioning cooling system are arranged in one plane substantially perpendicular to a direction in which a fuel cell vehicle moves forward at a front portion of the fuel cell. Also, heat exchangers are arranged in order of the condenser, the EV radiator, and the FC radiator, that is, in order of an operating temperature from an upper position to a lower position. An angle of plural fins fitted to a front grille is changed according to a load of a fuel cell and a vehicle speed, each of the plural fins being formed to have an elongate rectangular plate shape extending in a horizontal direction.

    摘要： In a ventilation duct of a cooling system, a level difference is formed between a wall located on a vehicle front side and a wall located on a vehicle rear side because a bottom end of the wall located on the vehicle front side is lower than a bottom end of the wall located on the vehicle rear side. The level difference makes a speed of a traveling wind flowing near an outlet faster than that flowing away from the outlet. Therefore, a pressure of the traveling wind flowing near the outlet decreases. As a result, air flows in the ventilation duct to be drawn to the neighborhood of the low-pressure outlet, and discharged out. Because cooling air including the traveling wind can be increased, heat radiation capacity of a radiator disposed in the ventilation duct is improved, and the cooling capacity of the cooling system can also be improved.

    摘要翻译： 在冷却系统的通风管道中，位于车辆前侧的壁与位于车辆后侧的壁之间形成有水平差，因为位于车辆前侧的壁的底端低于底部 位于车辆后方的墙的端部。 水平差使得出口附近的行进风速比从出口流出的速度快。 因此，在出口附近流动的行驶风的压力降低。 结果，空气在通风管道中流动，被吸引到低压出口附近，并排出。 由于能够提高包括行驶风的冷却空气，所以能够提高设置在通风管道内的散热器的散热能力，还能够提高冷却系统的冷却能力。

    摘要： A cooling water flow path 41 connected with a radiator 40 includes a fuel cell flow path 41a that makes circulation of cooling water from the radiator 40 via a fuel cell stack 20 to the radiator 40, and an exothermic equipment flow path 41b that is placed in parallel to the fuel cell flow path 41a and makes circulation of cooling water from the radiator 40 via exothermic equipment 13 (including an inverter 32 of a power control unit (PCU) 30, an air supplier 26, a heat exchanger 27, and a driving motor 35) to the radiator 40. The multiple pieces of exothermic equipment 13 are arranged in series along the exothermic equipment flow path 41b in the flow direction of cooling water in an ascending order of heat discharge quantity. The inverter 32, the heat exchanger 27, and the driving motor 35 are respectively equipped with a dual cooling mechanism, an air cooling mechanism, and an oil cooling mechanism. The arrangement of the invention ensures stable operations of the respective pieces of exothermic equipment 13 even when the cooling water used for cooling down the exothermic equipment 13 has a higher temperature.
