Abstract

The invention relates to a double-stage-supercharging air compressor system of a fuel cell vehicle. The double-stage-supercharging air compressor system of the fuel cell vehicle comprises a double-stage-supercharging air compressor body and an air compressor driver. The double-stage-supercharging air compressor body comprises double volutes, double impellers, a high-voltage direct-current motor and special cooling water flow channels. The air compressor driver comprises a voltage stabilizer, a rectifier, a fuse, a shielding layer, a circuit board and an internal program. In the operation process of the double-stage-supercharging air compressor, the rotation speed of the air compressor can be accurately controlled through the air compressor driver, it is guaranteed that the system can conduct accurate feedback in real time, and achievement of operation at a high rotation speed needs the cooling function of the special cooling water flow channels. Compared with the prior art, the double-stage-supercharging air compressor system of the fuel cell vehicle adopts the special cooling water flow channels and the shielding layer, it is guaranteed that the pressure and flow range requirements of the double-stage-supercharging air compressor system are met, and the double-stage-supercharging air compressor system of the fuel cell vehicle has the advantages of being high in rotation speed, low in electricity consumption, small in size, easy to maintain and the like.

Description

technical field [0001] The invention belongs to the technical field of automobile engines, and relates to a two-stage booster air compressor system for a fuel cell vehicle, in particular to a dual-cooling, high-speed, and large-flow two-stage booster air compressor system for a fuel cell vehicle. Background technique [0002] With the continuous growth of our country's national economy and the continuous improvement of people's living standards, cars have become an essential tool for people to travel. With the increase of smog in many cities in our country, people realize that the development of new energy is urgent. Automobiles are considered an important part of energy transformation, and proton exchange membrane fuel cell vehicles are considered to be the most mature representatives of new energy vehicles. It uses the chemical reaction between hydrogen and oxygen in the air to generate electricity to drive the car forward. It has a series of advantages such as simple stru...
