[Car fan] Why is it important
u003cbru003e As a key component in various fields, car fans are very important in quality and reliability. This will directly affect the service life of supporting products and is closely related to whether our common machines work normally. In the field of automation, fans also affect the performance and working life of products such as inverters, inverters, and soft starters due to their heat dissipation function, which is of key significance. Choosing a professional and responsible fan supplier is even more important. The boundary (housing) of the automobile fan, the cross-flow fan is generally composed of a curve GF (rear wall) with a gradually increasing gap with the impeller, a circular arc or other shape of the vortex tongue BD and the upper boundary DE. The length of the volute tongue and the angle γ between it and the upper boundary DE of the air outlet have a greater impact on the performance of the fan. The experiment found that when the vortex tongue BD has a certain length and the vortex center is at point C1, the fan can work normally and the fluid flow direction. The most important feature of automobile fans is that the fluid flows through the fan impeller twice, the fluid flows in the radial direction and then flows out in the radial direction. The intake and exhaust directions are in the same plane, and the exhaust body is evenly distributed along the width of the fan.
