Cooling device and cooling method

Abstract

The invention discloses a cooling device used for cooling an air compressor. The cooling device comprises at least one fan, a temperature sensor, a controller and a frequency converter, wherein the temperature sensor is used for detecting exhaust temperature of the air compressor; the controller is connected with the temperature sensor and is used for comparing the exhaust temperature with preset exhaust temperature and outputting a signal after comparison; and the frequency converter is respectively connected with the at least one fan and the controller and is used for controlling the at least one fan to output cooling air volume corresponding to the signal after comparison according to the signal after comparison. When the cooling device is in use, a cooing temperature is firstly set, the exhaust temperature of the air compressor is detected by the temperature sensor, when the controller determines that the temperature is lower than the cooling temperature, the power supply frequency of the fan is reduced by the frequency converter, the power of the corresponding fan can be reduced, and the cooling air volume is reduced, therefore, the energy consumption is reduced, the energy sources are saved, and the service life of lubricating oil in the air compressor is effectively prolonged simultaneously. The invention also discloses a cooling method.

Description

technical field [0001] The invention relates to the technical field of air compressor cooling, in particular to a cooling device and a cooling method. Background technique [0002] The air compressor is called air compressor for short, and the English name is air compressor. It is the main body of the air source device. It is a device that converts the mechanical energy of the prime mover, usually the motor, into gas pressure energy. When the air compressor is in use, it will generate heat by itself. Generally, a cooling fan will be set accordingly for cooling. The cooling fan can also be called a fan to prevent the air compressor from being overheated and affect the use. frequency operation, the cooling fan runs at full speed, even if such a large cooling air volume is not needed, it cannot be adjusted, which wastes energy. The fan runs at full speed for a long time, and the second cooling fan is turned on when the cooling air volume is not enough, and it also runs at full...

Problems solved by technology

When the air compressor is in use, it will generate heat by itself. Generally, a cooling fan will be set accordingly for cooling. The cooling fan can also be called a fan to prevent the air compressor from being overheated and affect the use. frequency operation, the cooling fan runs at full speed, even if such a large cooling air volume is not needed, it cannot be adjusted, which wastes energy. The fan runs at full speed for a long time, and the second cooling fan is turned on when the cooling air volume is not enough, and it also runs at full speed. When the cooling air volume provided by the two cooling fans running at full speed is too large, it cannot be adjusted, wasting energy, and cooling air volume at the same time small adjustment range
