Abstract

The invention discloses a thermal management system for a fuel cell of a commercial vehicle. The thermal management system comprises a controller, a hydrogen fuel cell system, an electric control three-way valve, an electric heater, a radiator, a variable frequency fan, a make-up water tank, a variable frequency water pump, a deionizer, a throttle valve, a particulate matter filter, a temperaturesensor I and a temperature sensor II. Due to the cell thermal management system, a coolant of the thermal management system flows through small circulation and is rapidly warmed when the vehicle is started at the low temperature, the temperature of the coolant is guaranteed to reach the optimal temperature range for the reaction of the hydrogen fuel cell within a short period of time, the reactionefficiency of the hydrogen fuel cell is improved, the small circulation of the coolant is gradually switched to large circulation through the electric control three-way valve after the temperature ofthe coolant reaches the set optimal reaction temperature range, a better cooling effect is achieved, the hydrogen fuel cell is within the optimal reaction temperature range, and the reaction efficiency is improved. The rapid warming of the thermal management system in the cold start also reduces the damage on the cell, and the service life of the cell is prolonged.

Description

technical field [0001] The invention relates to a fuel cell thermal management system, in particular to a commercial vehicle fuel cell thermal management system. Background technique [0002] Hydrogen fuel cell vehicles are favored by governments around the world because of their high energy conversion efficiency, clean water, and low operating noise. They are truly zero-emission and zero-pollution vehicles. Started research and development of hydrogen fuel cell vehicles. Hydrogen fuel cells have high requirements on the control accuracy of the reaction temperature, and the control accuracy of the battery reaction temperature is not enough, which will reduce the reaction efficiency of the hydrogen fuel cell. At the same time, the heating speed of commercial vehicles is slow after starting in a low temperature environment, which will affect the service life of the hydrogen fuel cell. Contents of the invention [0003] The invention provides a commercial vehicle fuel cell t...
