There are many types of cooling fans, and each type has its own limitations. The noise of the cooling fan is mainly aerodynamic noise, while the noise of the centrifugal fan is mainly low-frequency noise, which decreases with the increase of frequency. Commonly used axial flow fans are dominated by intermediate frequency noise.
The development of cooling fans has a profound experience. With the rapid development of contemporary society, some industrial equipment that easily generates high heat has higher and higher requirements for the quality of cooling fans. Some better cooling fans can at the same time have high air volume, low noise, and long life. How to achieve and improve these environments?
Of course, these conditions are achieved by the R&D department and manufacturing department of the cooling fan manufacturer. The R&D department and manufacturing department of each heat sink manufacturer are different, and there are many factors to consider. Occasionally, the research and development of new products will be increased according to the needs of customers, so every product developed by the cooling fan manufacturing department is very tight.
In the design and development, it is necessary to fully consider and test the wind resistance and auxiliary wind resistance of various cooling fan shapes, how to achieve perfection when the wind resistance and good pressure are inserted, how to minimize the bearing conflict in the fan, how to make the chip to maximize the performance of the fan, and ensure the safety of the fan , These need to be dealt with by the R&D department. When the breeze pressure speed of the structural components in the DC cooling fan are completely similar, the outer frame is well designed, 20% higher than the other outer frame, and this outer frame is well designed, 20 higher than the other outer frame. %, we can see the tension of developing a product.
