Heat control system for tramcar

The invention provides a heat control system for a tramcar. The heat control system for the tramcar comprises a roof sectional material, a fuel battery system and an air conditioner system, wherein the roof sectional material is arranged above a tramcar carriage top plate, and the fuel battery system and the air conditioner system are respectively arranged above the roof sectional material. The heat control system is characterized by also comprising a heat radiating system which is arranged above the roof sectional material, the fuel battery system is connected with the heat radiating system through a pipeline, and the pipeline is provided with a cycling pump which is used for pumping a refrigerant to the heat radiating system. By adopting the heat control system, the problem of the low heat radiation efficiency can be solved.
