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.

Claims

1. 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.

2. The system according to claim 1, wherein a through-hole is arranged in the roof profile near the heat dissipating system, and the through-hole is configured to input the cold air produced by the air-conditioning system into the heat dissipating system, creating a heat exchange between the coolant and the cold air.

3. The system according to claim 1, wherein a through-hole is arranged in the roof profile near the heat dissipating system, and the through-hole is configured to input the cold air produced by the air-conditioning system into the heat dissipating system, creating a heat exchange between the coolant and the cold air.

4. The system according to claim 1, wherein a through-hole is arranged in the roof profile near the heat dissipating system, and the through-hole is configured to input the cold air produced by the air-conditioning system into the heat dissipating system, creating a heat exchange between the coolant and the cold air.

5. The system according to claim 1, wherein a vertical hole connected with an air-conditioning duct is arranged in the hollow air duct, wherein the air-conditioning duct is arranged beneath the compartment roof and in a compartment.

6. The system according to claim 1, wherein an outlet of the circulating pump is connected with a three port valve, which is used for connecting the outlet of the circulating pump to the heat dissipating system and a piping leading to the fuel cell system, respectively.
