The cooling fan includes a booster fan, which is also called a linear fan. How do you call it a linear fan? This is based on the special name of the fan, that is, the wind blown out is a straight line.
The supercharged fan is also a linear fan. As the name suggests, this is that the wind blowing out is a straight line. It changes the wind direction through the turbine-type scattered frame and multiple thorns. This thorn is arc-shaped. After software design and simulation, the fan blows out in a spiral, so as to achieve a straight direction. It is characterized by operation. Strong stability, good heat dissipation effect and long service life.
How to choose the most suitable fan?
1. Look at the current ----- the same speed, the same voltage, the same air volume. Current small cooling fan is better. Because the smaller the current, the smaller the fan loss, that is, the smaller the energy consumption.
2. listen to the noise-the same speed, the same voltage, the lower the noise, the better the cooling fan, because the low noise is mainly related to the fan blade, bearing, oil, assembly structure, etc. 1> the better the shape design of the fan blade, the greater the air volume and the lower the noise. this is a technical process and also tests the ability of technicians lt;2> the higher the bearing accuracy, then the smaller the friction with the shaft core, the more accurate the size matching, and of course the noise will be lower. This is closely related to the material of the bearing.<3> The lower the noise, it means that the friction is small, the bearing and the shaft core The life will be longer, and the life of the DC fan will also be longer.
3. Measure vibration ------ For fans of the same specification and speed, a cooling fan with low vibration is better. The smaller the vibration, the more stable the fan will run, the smaller the loss of the bearing and shaft core, and of course the life will be longer.
