[0002] The prior art discloses a connection structure between an air-water separator and a radiator of a fuel cell, with an authorization announcement number of CN220367946U and an authorization announcement date of 2024.01.19. The function of the radiator is to transfer the heat of the coolant to the environment and reduce the temperature of the coolant.

The coolant flows out from the coolant outlet without being completely cooled, affecting the heat dissipation efficiency. Utility Model Content
