Abstract

The invention relates to a radiator and a radiating system of a fuel cell and a vehicle. The radiator of the fuel cell comprises a radiator shell (31) and a plurality of fans (32) integrated and fixedon the radiator shell. A first heat dissipation loop (111) and a second heat dissipation loop (112) which are separated by an isolation cavity (30) are arranged in the radiator shell (31). The firstheat dissipation loop is used for heat dissipation of a fuel cell stack (4), and the second heat dissipation loop (112) is used for heat dissipation of a fuel cell accessory (5). A radiator for a fuelcell stack and a radiator for a fuel cell accessory are integrally designed into one radiator; namely, the heat dissipation of the fuel cell stack and the heat dissipation of the fuel cell accessories are connected in parallel and share one group of fans, and the heat dissipation of the fuel cell stack and the heat dissipation of the accessories are respectively completed through two independentheat dissipation loops, so that the heat dissipation capability of the parallel radiator can be fully utilized, the maximization of the heat dissipation efficiency is ensured, and the utilization efficiency of space is improved.

Description

technical field [0001] The present disclosure relates to the field of heat dissipation of fuel cells, and in particular, relates to a heat sink of a fuel cell, a heat dissipation system and a vehicle. Background technique [0002] Fuel cells, as a power generation device that directly converts chemical energy into electrical energy, have the advantages of zero emission, no pollution, high efficiency, and low noise. They have broad application prospects and huge market potential in the transportation field. However, fuel cells The higher the output power of the fuel cell, the more heat will be generated. If the heat cannot be released in time and effectively, it will seriously affect the life of the fuel cell. Therefore, the heat dissipation of the fuel cell is one of the problems that must be solved. In the related art, the heat dissipation system for fuel cells includes the main radiator for heat dissipation of the fuel cell stack and the auxiliary radiator for accessories ...
