Problems solved by technology

[0005] At present, hydrogen fuel cell power supply technology has not yet been applied in engineering applications in the field of domestic rail transit. Research has been conducted on the supporting cooling technology for rail vehicles using hydrogen fuel cell power supply technology, and research has been developed to meet the heat dissipation, flow resistance and noise of hydrogen fuel cell powered rail vehicles. Cooling technology with such performance requirements is imminent

Abstract

The invention discloses a cooling device used for a hydrogen cell railway vehicle. The cooling device comprises an air filtering device, a water cooler, a top protection net, expansion tanks, water injection valves, shock absorbers, electrical connectors, a box, fan sets, water supply pipes, cooler water inlet pipes and cooler water outlet pipes. All the parts are integrated on the same box to be installed at the top of the railway vehicle. The cooling device can meet the cooling requirements of railway vehicles adopting power supply technologies of hydrogen cells different in power and grade, and the cooling technology and the cooling product are provided for railway vehicles, adopting the power supply technologies of hydrogen cells, in China.

Description

Technical field [0001] The invention relates to the field of heat exchange for new energy rail vehicles, in particular to a cooling device for hydrogen fuel cell rail vehicles. Background technique [0002] The traction power of domestic rail transit generally uses electric traction (electrified railway) or diesel traction (non-electrified railway or electrified railway), and new energy traction power rail vehicles are still in a blank. [0003] Fuel cell power, which uses hydrogen as an energy source for power generation, is one of the clean energy technologies and is in line with the country's future clean energy strategy. In view of its advantages of cleanliness, high efficiency, and no pollution to the environment, relevant institutions at home and abroad are stepping up in-depth technical research and engineering application promotion. In the field of rail transit, fuel cell power supply technology is still in the early stages of development at home and abroad. In order to pr...
