Embodiment Construction

[0018] see figure 1 , the present invention comprises a speed-adjustable water-cooled DC high-speed motor 12, and the two axial ends of the water-cooled DC high-speed motor 12 are respectively equipped with split couplings 11, through which the split shaft couplings 11 are connected with the compressor 7 and the expander respectively. 13 connected. The water-cooled DC high-speed motor 12 is located between the compressor 7 and the expander 13, fixed on the two supports 10, and plays a connecting role. A compressor 7 and an expander 13 are respectively seated on the supports 10 on both sides. The coaxiality of the cold DC high-speed motor 12, the compressor 7 and the expander 13 is guaranteed by the matching structure on both sides of the support 10. Therefore, in actual use, the compressor, expander and water-cooled DC high-speed motor can be axially withdrawn very conveniently without cumbersome alignment.

[0019] The aforementioned compressor 7 and expander 13 have exact...

Abstract

This invention discloses one fuel battery automobile screw lever contracting expansion set, wherein, the contracting machine, direct current water flow high speed motor and expansion machine are connected through axis fixing to ensure the matching structure through two sockets of both ends; the contracting machine and expansion machine comprise one pair of rotors, drawing terminals, exhaust terminal, gas cylinders with water chambers. Socket element and one pair of synchronization gear; the expansion machine and contracting machine parts are highly united and exchangeable and the cooling water is the water generated by the fuel battery.

Description

technical field [0001] The invention belongs to the field of power machinery, in particular to a screw compression-expansion unit for a fuel cell vehicle using compressed air as an oxidant. Background technique [0002] A fuel cell is an electrochemical device that combines hydrogen and oxygen through an electrochemical method to directly generate electricity and heat and discharge water without polluting the environment. It has become the first choice for future energy replacement due to its abundant fuel sources, no pollution to the environment, high efficiency, and noiseless work. [0003] With the development of industry, the air pollution and noise pollution brought by internal combustion engines powered by fossil fuels are increasingly restricted by national laws and regulations. At the same time, due to the shortage of fuel and the limitation of the thermal efficiency of the Carnot cycle, it has been difficult to improve the efficiency of ve...
