[0002] Air compressor is widely used, and there are many types. According to the heat dissipation mode of air compressor, it can be divided into air-cooled, water-cooled and oil-cooled, among which air-cooled refers to the heat generated by the air compressor being discharged to the atmosphere by the fan, and water-cooled and oil-cooled use cooling water and cooling oil as heat exchange medium to cool the air compressor. In the papermaking and thermal power industry, in order to save water, at present, single machine capacity below 45Nm 3 / min screw air compressor mostly adopts air-cooled type. The heat generated by the air compressor in the past is discharged to the atmosphere by the exhaust fan, which is unorganized, disordered and uncontrollable, and then discharged to the workshop outside by mechanical exhaust. This disordered discharge makes the temperature in the workshop unable to be adjusted. Therefore, from the perspective of energy saving and environmental protection, the heat generated by the air compressor should be fully utilized to convert it into energy that can be reused in enterprises or daily life.
