Thermal control system for tramcar

A thermal control system for a tramcar, comprising a roof profile arranged above a compartment roof of the tramcar, and a fuel cell system and an air-conditioning system arranged above the roof profile, the thermal control system further comprising:

• a heat dissipating system arranged above the roof profile that is connected with the fuel cell system via a piping, the piping being provided with a circulating pump for pumping a coolant to the heat dissipating system,
• wherein a heat-conducting medium is arranged between the heat dissipating system and the roof profile, to transfer, to the roof profile, heat of the coolant outputted from the fuel cell system;
• and wherein the roof profile is internally arranged with a hollow air duct that is configured to form convection between the heat of the coolant transferred to the roof profile from the coolant and cold air produced by the air-conditioning system.
