Problems solved by technology

[0004] However, the inventors found that this method only utilizes the waste heat of the fuel cell stack to heat the passenger compartment in winter, and exchanges heat with the air through the waste heat of the fuel cell stack. The heat exchange efficiency is low, and the waste heat of the fuel cell stack is not fully utilized. Heap waste heat utilization rate is low

Embodiment Construction

[0055] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0056] In the prior art, when the waste heat of the fuel cell stack is reused, the waste heat of the fuel cell stack is mainly used to heat the passenger cabin. The battery stack coolant heats the air blown over the surface of the air-conditioning radiator to heat the passenger compartment in winter. However, this method uses the waste heat of th...

Abstract

The embodiment of the invention provides fuel cell stack thermal management equipment, method and system. The system comprises a fuel cell stack, an energy accumulator, a compressor, an outdoor heat exchanger, an indoor heat exchanger and a radiator assembly, wherein the fuel cell stack and the energy accumulator form an energy accumulator loop through a cooling liquid pipeline; the fuel cell stack and the outdoor heat exchanger form a coupling air conditioning loop through a cooling liquid pipeline; the outdoor heat exchanger, the compressor and the indoor heat exchanger form a vehicle-mounted air conditioner loop through a cooling liquid pipeline; and the fuel cell stack and the radiator assembly form a system heat dissipation loop through a cooling liquid pipeline. According to the embodiment of the invention, the utilization efficiency of waste heat of the fuel cell stack can be improved, and the fuel cell stack can be ensured to be at a proper working temperature.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of fuel cell stacks, and in particular to a thermal management device, method and system for a fuel cell stack. Background technique [0002] As a new type of green power source, fuel cell engine is widely used in the automotive field due to its advantages of zero pollution, high efficiency, and long cruising range. The fuel cell stack will generate a lot of waste heat during operation, how to reuse the waste heat of the fuel cell stack is a hot spot of current research. [0003] In the prior art, by exchanging heat between the fuel cell stack coolant and the air circulation system of the air conditioner, the fuel cell stack coolant is used to heat the air blown over the surface of the air conditioner radiator, thereby heating the passenger compartment in winter. [0004] However, the inventors found that this method only utilizes the waste heat of the fuel cell stack to heat the passe...
