Background
The traditional screw air compressor cooling system basically adopts a top blowing cooling method, an oil side cooler and an air side cooler are integrally installed at the top of a housing, and an axial flow fan is hung at the top together through an air guide cover. All heat exchange air quantity passes through the air inlet outside the housing, takes away other heat generated by equipment in the housing, and is exhausted forcibly through the fan. The traditional scheme has the following disadvantages: 1. when the fan during operation, when wind blows to the cooler, the heat can be taken away through the cooler to the overwhelming majority wind, and a small part of wind can be blocked and get back to in the box to reduce cooling efficiency. 2. All wind needs to enter from the air inlet, and the air inlet area of the air inlet needs to be enlarged, so that noise inside the housing is easier to conduct to the outside. 3. The cooler itself is heavy (especially for high power machines) and the whole arrangement on top is liable to cause excessive internal stresses and hence cracking. 4. Dust and lint in the air can easily cause blockage of the cooler, so that the cooler needs to be cleaned frequently at a later stage. The cooler placed on top is cumbersome to clean.
