There are many people in electrical appliances, machinery, and medical industries. They only know that the high temperature of the equipment needs to use the cooling fan to dissipate the heat of the mechanical equipment, but they do not know how many types of cooling fans there are. Different cooling fans are used in different industries. Xin super speed company will guide you some knowledge of the difference between the types of cooling fans:
, According to the different materials they are made of, they can be divided into FRP fans, iron fans, plastic fans, aluminum fans and so on.
Second, according to their different gas flow directions, they can be divided into axial flow fans, diagonal flow fans, mixed flow fans, centrifugal fans and cross flow fans.
Third, according to their different outlet pressures, they can be divided into fans, fans and compressors
The performance of the cooling fan is determined by flow, pressure, power, efficiency and speed. In addition, the size of noise and vibration is also the main design index of the cooling fan. Flow is also called air volume, which is expressed by the volume of gas flowing through the fan per unit time; pressure is also called wind pressure, which refers to the pressure rise of the gas in the fan, which can be divided into static pressure, dynamic pressure and total pressure; power refers to the fan The input power is the shaft power. The ratio of the effective power of the fan to the shaft power is called efficiency. The full pressure efficiency of the fan can reach 90%.
