Intelligent thermal management system for methanol fuel cell vehicle

Abstract

The invention discloses an intelligent thermal management system for a methanol fuel cell automobile. According to the technical scheme, the intelligent thermal management system for the methanol fuelcell automobile comprises a fuel cell stack cooling circulation loop, an external air cooling circulation loop and a control system, wherein excess heat generated by a fuel cell is brought into a multi-medium heat exchanger through the fuel cell stack cooling circulation loop, and heat is conducted out to an external air cooler for dissipation by heat exchange of the multi-medium heat exchanger;the external air cooler adopts a stepless-speed electronic fan, and high-temperature tail gas generated by fuel cells can be cooled and directly discharged by the multi-medium heat exchanger; the controller acquires temperature signals through a temperature sensor, performs calculation, controls an electronic pump to adjust the flow rate of each medium and the rotating speed of the fan of the external air cooler, can perform CAN communication with a whole automobile control system and meets traveling requirements of different working conditions of the automobile, and the heat balance of the whole fuel cell system is guaranteed.

Description

Technical field [0001] The invention relates to the field of methanol fuel cell vehicle cooling systems and the field of fuel cell intelligent thermal management systems. Background technique [0002] At present, the solution of environmental problems in our country has become increasingly urgent. The smog and air pollution caused by automobile exhaust emissions in cities have seriously affected the health of the urban population. In response to this problem, the state has made vigorous policy encouragement for the development of new energy vehicles, and the development of new energy vehicle technology has become the general trend. The methanol fuel cell vehicle in the new energy vehicle category has the advantages of safety, energy saving, and high efficiency, but some high-temperature methanol fuel cell applications in vehicles still have technical defects. Due to its high working temperature, it will generate more waste heat and cause energy waste. At the same time, the tempe...

AI Technical Summary

Problems solved by technology

The methanol fuel cell vehicle in the new energy vehicle category has the advantages of safety, energy saving, and high efficiency, but there are still technical defects in the application of some high-temperature methanol fuel cells in vehicles.

Due to its high working temperature, it will generate a lot of waste heat, resulting in energy waste. At the same time, it is difficult to control the temperature during the use of the vehicle. When the vehicle starts, it needs to wait for the fuel cell to heat up, which causes inconvenience in the use of the vehicle.
