  • Patent number: 10320010
    Abstract: Disclosed is a thermal control system for a tramcar. The system includes a roof profile (11) arranged above a compartment roof of the tramcar (10); a fuel cell system (12) and an air-conditioning system (14) arranged above the roof profile (11); and a heat dissipating system (13) arranged above the roof profile (11), where the fuel cell system (12) communicates with the heat dissipating system (13) via a piping (16), and the piping (16) is arranged with a circulating pump (15) for pumping a coolant to the heat dissipating system. The thermal control system solves the problem of low heat dissipating efficiency of a fuel cell in the prior art.
