The cooling water pump 3 is connected to the large circulation heating pipe, and a water inlet sensor 4 is installed between the cooling water pump 3 and the large circulation heating pipe. The large circulation heating pipe is connected to the electronic thermostat 7, and a water outlet sensor 6 is installed between the large circulation heating pipe and the electronic thermostat 7. The electronic thermostat 7 is connected to the cooling fan 8; the cooling water pump is mainly used for the cooling water transportation of the large and small circulation loops of thermal management and the temperature of the large and small circulations of thermal management. According to the temperature feedback from the temperature sensor of the large and small circulation loops, the intelligent advanced PID is used to adjust the speed of the circulation water pump in real time; the teaching radiator system is used to control the cooling water temperature of the large and small circulation loops of thermal management.

[0021] The hydrogen fuel cell thermal management training platform mainly uses radiators and water pumps for heat dissipation. Heaters are equipped in both large and small circulation pipelines to simulate the heating process of the air compressor and its controller, DC / DC, and stack. In the large circulation loop, the cooling water enters the stack and the intercooler for heat exchange, and then exchanges heat with the ambient cold air through the external radiator. Then the cooled cooling water is sent back to the fuel cell stack by the circulating water pump to complete the cooling water cycle. In the small circulation loop, the water pump sends the low-temperature water at the radiator outlet into the air compressor and its controller, DC / DC, and takes away its excess heat. The heated cooling water returns to the radiator and transfers the heat to the surrounding environment through convection heat exchange, thereby realizing the temperature control of the auxiliary system.
