Abstract

The invention belongs to the technical field of new energy vehicles, and particularly relates to a fuel cell cooling module and a fuel cell cooling system. The fuel cell cooling module comprises a first refrigerator and a first radiator, the first refrigerator is arranged to reduce the temperature of a gas, the first radiator is arranged behind the first refrigerator along the flowing direction ofthe gas, the first radiator is arranged to be connected with a fuel cell and cool the fuel cell, the gas flows to the first radiator along the first refrigerator after being cooled, and the gas is arranged to cool the first radiator. A cooling liquid exchanges heat with surrounding gas through the first radiator to reduce the temperature of the cooling liquid so as to cool the fuel cell, and thetemperature of the gas flowing to the first radiator is reduced through the first refrigerator, so the temperature difference between the gas and the cooling liquid is increased, and the problem thatthe heat dissipation effect is poor due to the fact that the temperature difference between the gas and the cooling liquid is small in high-temperature weather is solved.

Description

technical field [0001] The invention belongs to the technical field of new energy vehicles, and in particular relates to a fuel cell cooling module and a fuel cell cooling system. Background technique [0002] This section provides background information related to the present disclosure only and is not necessarily prior art. [0003] The power generation efficiency of the fuel cell is about 50%. The fuel cell will generate a lot of heat when it supplies power. If this part of the heat is not dissipated in time, it will affect the operation of the fuel cell. Therefore, cooling components are installed around the fuel cell, including coolers, air compressors and controllers, etc., and these heat sources require a low water temperature limit, that is, the cooling module is required to dissipate a large amount of heat under the condition of low liquid-to-air temperature difference. [0004] The common arrangement of cooling modules for fuel cell vehicles in the prior art is an...
