The selection of the cooling fan is a complex process, which requires high technical requirements. The selection method of cooling fan are many, such as selection, according to the logarithmic curve by dimensionless characteristic curve selection, and selection of fan cooling professional software can also help us selection. No matter what kind of choice in the selection of cooling fan, we have to grasp some of the basic principles.

1, the use of cooling fan is the determining factor

The purpose of the use of heat dissipation fan performance, and the performance of the decision makers, so the purpose of the use of cooling fan is the first factor to be considered in the selection. The purpose of the cooling fan is directly related to the state of the heat transfer fan, the physical and chemical properties of the gas are different, and the type of the cooling fan is also very different.

The gas cooling fan delivery if there is flammable and explosive characteristics, we should choose the explosion-proof cooling fan; gas cooling fan delivery if contains a lot of dust or conveying of pulverized coal, dust, coal to choose cooling fan; gas cooling fan transporting corrosive strong, want to choose anticorrosive cooling fan; under high temperature or high temperature gas delivery, to select high temperature cooling fan.

2, the choice of manufacturers of cooling fan

After the use of the cooling fan is determined, according to the performance requirements of the cooling fan, first determine the level of the cooling fan, the decision is to choose the domestic heat fan or imported cooling fan. Then, to a certain level of heat dissipation fan manufacturers do a basic understanding of the cooling fan manufacturers to determine the production capacity, product quality, product specifications and other information, but also consider the level of environmental protection of the cooling fan.

Cooling fan selection process, but also to consider the manufacturer's technical strength, maintenance level, the follow-up of the cooling fan service is timely, can ensure the normal use of the cooling fan. In addition, the performance of the cooling fan manufacturers in the development of new products, can reflect its technical strength, should also be included in the scope of selection considerations.
