散热风机选型主要看散热风机品牌、性能、用途、生产制造商，在不同的工作环境中要选择适合的散热风机，比如防爆散热风机、排尘散热风机、防腐散热风机以及耐温散热风机等等，散热风机的选购是一个比较复杂的过程，对技术要求很高。

　　The selection of cooling fan mainly depends on the brand, performance and manufacturer of the cooling fan. In different working environment, it is necessary to select suitable cooling fan, such as explosion-proof cooling fan, dust exhaust fan, anti-corrosion cooling fan and temperature resistant cooling fan, etc. the selection of cooling fan is a relatively complex process and has high technical requirements.

　　1、散热风机的用途是决定因素

　　1. The use of cooling fan is the decisive factor

　　散热风机的用途决定性能，而性能决定散热风机的品牌及生产制造商，因此散热风机的用途是选型时要放在第一位考虑的因素。散热风机的用途和散热风机输送气体的状态直接相关，气体物理条件和化学性质不同，所采用的散热风机类型也有很大区别。

　　The purpose of the cooling fan determines the performance, and the performance determines the brand and manufacturer of the cooling fan. Therefore, the use of the cooling fan is the first factor to be considered when selecting the type. The purpose of the cooling fan is directly related to the state of the gas transported by the cooling fan. The types of the cooling fan used are also very different due to the different physical conditions and chemical properties of the gas.

　　散热风机输送的气体如果有易燃、易爆的特性，则要选择防爆散热风机；

　　If the gas transported by the cooling fan is flammable and explosive, the explosion-proof cooling fan should be selected;

　　散热风机输送的气体如果含有大量粉尘或是输送煤粉，要选择排尘、煤粉散热风机；

　　If the gas transported by the cooling fan contains a large amount of dust or pulverized coal, it is necessary to select the dust exhausting and pulverized coal cooling fan;

　　散热风机要输送的气体有比较强的腐蚀性时，要选择防腐散热风机；

　　When the gas to be transported by the cooling fan has strong corrosivity, the anti-corrosion cooling fan should be selected;

　　在高温条件下工作或输送高温气体，要选择耐温散热风机。

　　In high-temperature conditions or transport high-temperature gas, to choose a temperature resistant cooling fan.

　　2、散热风机的制造商选择

　　2. Manufacturer selection of cooling fan

　　散热风机的用途确定后，可以根据散热风机的性能要求，首先确定散热风机的档次，决定是选用国产散热风机或进口散热风机。而后，要对特定档次的散热风机制造商做基本了解，确定散热风机制造商的生产能力、产品质量、产品规格等信息，还要考虑散热风机的环保水平。

　　After the purpose of the cooling fan is determined, the grade of the cooling fan can be determined first according to the performance requirements of the cooling fan, and the decision is to select the domestic cooling fan or the imported cooling fan. Then, it is necessary to have a basic understanding of the manufacturers of cooling fans of a specific grade, and determine the production capacity, product quality, product specifications and other information of the manufacturers of cooling fans, and also consider the environmental protection level of the cooling fans.

　　散热风机选型过程中，还要考虑制造商的技术实力、维修水平，对散热风机的后续服务是否及时，能否保证散热风机的正常使用。另外，散热风机制造商在新产品开发方面的表现，能体现其技术实力，也应列入选型考虑范围。

　　In the selection process of cooling fan, the technical strength and maintenance level of the manufacturer should be considered, whether the follow-up service of the cooling fan is timely and whether the normal use of the cooling fan can be guaranteed. In addition, the performance of cooling fan manufacturers in the development of new products can reflect their technical strength, which should also be included in the scope of selection.
