There are many types of cooling fans, and each type has different application areas. The noise of some cooling fans is mainly aerodynamic noise, while the noise of centrifugal fans is mainly low-frequency noise, which decreases as the frequency increases. The widely used axial flow fans are mainly mid-frequency noise.
The development history of cooling fans is very long. With the rapid development of modern society, some equipment industries that are prone to high heat have higher and higher requirements for the quality of cooling fans. Some better cooling fans may have high air volume, low noise and long service life at the same time. How to achieve and improve these conditions?
Of course, these conditions are achieved by the R&D department and production department of the cooling fan manufacturer. The R&D department and production department of each cooling fan manufacturer are different, and there are many factors to consider. Sometimes new product development is added according to customer needs, so every product developed by the cooling fan manufacturer's department is very important.
In the design and development of the cooling fan frame, it is necessary to consider and test the resistance and auxiliary force of various frame shapes to ventilation, how to achieve the perfect point when the wind and air pressure cross, how to minimize the bearing friction inside the fan, and how to make the chip To maximize the performance of the auxiliary fan and ensure the safety of the fan, these need to be dealt with by the R&D department. When the internal structural components and wind pressure speed of the two DC cooling fans are exactly the same, the outer frames of different shapes are used for testing. The performance of this kind of outer frame is very good, and the performance of the fan is 20% higher than that of the other general fan. This shows the importance of developing a product.
The production department is also very important. A good production department can improve the quality of the entire product by about 40%, and a good production department can increase the delivery speed and save production costs. For example, a skilled welding worker can avoid the failure rate of the fan and improve the stability of the cooling fan to a large extent.
