DC cooling fanThe type of fan blade is generally classified according to the shape of the fan blade, because the shape of the fan blade can directly determine the performance characteristics of the fan. Fan blades are usually divided into thin right angles, thick angles and thin angles. It is far-fetched to say that turbofans are another type of fan blades.
Thin right-angle fan blades are the earliest products, but so far not out of date. The fan using this kind of DC fan blade can only perform well in terms of noise, air pressure, air volume, service life, etc., and is suitable for products with low calorific value.
Thick curved fan blades have the best heat dissipation capacity, because it produces large wind pressure and sufficient air volume, which is also conducive to the improvement of cold and heat exchange speed. However, thicker curved blades will bring greater noise, the centrifugal force on the shaft will be greater when rotating, and the wear will be serious, which will also have a certain impact on the service life. Such fan blades are usually used for violent fans that provide greater air flow.
The curved fan blades are improved on the basis of thick curved fan blades. There are many blades for DC cooling fans, and the air volume can basically be guaranteed. In addition, due to the light weight of the blades, the speed is high, the speed is uniform, and the noise is not large. But the biggest disadvantage of thin curved blades is that the wind pressure is slightly smaller, leaving a trace of regret for everyone.
