Cooling structure of air compressor motor

Abstract

The invention discloses a cooling structure of an air compressor motor. The cooling structure comprises a compressor and an electric motor, wherein the electric motor is used for driving the compressor to work, an air inlet pipeline for air suction is arranged on the compressor, a sealed box is arranged at the middle part of the air inlet pipeline, the electric motor is arranged in the sealed box, and sucked air reaches the compressor after passing through the electric motor. In the cooling structure, the electric motor is arranged in the sealed box, forced convection cooling to the electric motor is carried out by using the sucked air, so that a cooling fan arranged at a tail rotor of the electric motor and a fan cover at the tail of the electric motor can be omitted, the volume of the electric motor is reduced, and the output power of the electric motor is increased; meanwhile, the cooling efficiency of the electric motor is changed with the power change of the electric motor, and the cooling of the electric motor having different powers is ensured; air passing through the surface of the electric motor is air filtered by an air cleaner, so that the damage of dust to the electric motor can be reduced; and the electric motor is arranged in the sealed box, therefore, noise caused by the electric motor per se also can be reduced.

Description

technical field [0001] The invention relates to the field of air compressors, in particular to an air compressor motor heat dissipation structure. Background technique [0002] Air compressors, referred to as air compressors, are widely used in the field of industrial and agricultural production as general-purpose mechanical equipment. The market size of the air compressor industry in my country is growing at an annual growth rate of more than 8%, and the market scale is expanding rapidly. [0003] However, as the motor of air compressor power equipment, its failure rate is generally higher than that of other equipment. The reasons for the damage of the air compressor motor are multifaceted and comprehensive. In addition to the common fault factors with other power equipment motors, it is also related to the fault factors of the specific operation and production of the air compressor itself, but the damage of the air compressor motor is the most One of the main reasons is t...

AI Technical Summary

Problems solved by technology

[0005] The motor with fan cooling at the tail of the rotor has poor heat dissipation, and the output power of the motor is reduced due to the ventilation and friction loss caused by the rotation of the fan and bearing. At the same time, the fan and windshield at the tail of the rotor also increase the volume of the motor itself

The way of using a special small motor to drive the fan to rotate, one is to increase the extra power consumption, and the other is that when the small motor has a problem, if it is not found in time, it will easily cause the temperature of the air compressor motor to rise and burn out
