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.
摘要:
The present invention provides a hybrid power rail vehicle power supply box and a hybrid power rail vehicle. The hybrid power rail vehicle power supply box includes: a closed box body (10); a blowing pipe (2) that is fixedly arranged on one side outside the box body (10), is provided with an inlet (21) and at least one blowing branch pipe (22), and is communicated with the box body (10); a discharging pipe (3) that is fixedly arranged on other side outside the box body (10), is provided with an outlet and at least one discharging branch pipe (32), and is communicated with the box body (10) via the discharging branch pipe (32). The hybrid power rail vehicle power supply box can effectively cool the power supply box, protecting the power pack inside thereof, and satisfying outside mounting requirements of the vehicle.
