an air compressor

Abstract

The invention relates to an air compressor. Flaky heat dissipation fins are arranged on the surfaces of air cylinders and cylinder covers, and the output end of a motor is connected with a heat dissipation fan. Guide covers are arranged between the heat dissipation fan and the air cylinders and the cylinder covers. The output of the motor drives the fan to conduct heat dissipation on the air cylinders and the cylinder covers meanwhile pressurizing is conducted. According to the air compressor, the heat dissipation efficiency of the air compressor is greatly improved, the exhaust gas temperature can be effectively lowered, thus, the temperature of a piston and a piston ring is also lowered, and the life of the piston ring is prolonged; and in addition, waterproof and dustproof treatment is conducted on the motor, a box body, the air cylinders and the cylinder covers, so that the air compressor has a good waterproof and dustproof grade.

[0002] At present, in the field of public transportation, the share of new energy vehicles is getting higher and higher. There are many pneumatic components inside new energy vehicles, so air compressors are needed to provide air sources. The current air compressors mainly include motors, boxes, cylinders and missing covers. and other components, the noise and vibration of the existing conventional air compressor are relatively large, and the waterproof performance level is low, which cannot meet the needs of new energy vehicles

[0003] The air compressor is installed inside the new energy vehicle, and the space is narrow. The heat dissipation performance of the air compressor is high, and the heat dissipation performance of the existing air compressor cannot meet the needs well.

[0004] In addition, the inner wall of the existing air compressor cylinder is coated with wear-resistant materials such as graphite, and the piston ring is generally made of polytetrafluoroethylene rings. When the air compressor is working, toxic gases will be produced. Because the ventilation is better in ordinary workshops, this trace amount of toxic gases The gas is not harmful to the human body, but the new energy vehicle in the sealed space will, a small amount of toxic gas enter the compartment with the air conditioning system, which is more harmful; at the same time, wear-resistant materials such as graphite have poor thermal conductivity and hinder the heat transfer layer. , the heat generated by the piston cannot be transferred to the cylinder in time, which will cause a large temperature difference between the inside and outside and affect the heat dissipation performance of the air machine
