Many customers still have a high impression of imported cooling fans. Indeed, imported cooling fans have good performance, especially Japanese brands such as NMB, NIDEC, Panasonic, SANYO and other well-known brands. What are their advantages in cooling fans? What?
The most important thing is design. Japanese brands are ahead. The most primitive designs, such as the shape of fan blades. Brands in mainland China still have a way to go in this regard. They use fluid mechanics to simulate the N points of the fan blade. The fan blade body allows the fan blades to run in a limited space with loud wind and quiet sound. At present, I have not heard of any domestic-funded cooling fan manufacturer that can do it.
What we are doing now is to follow the Japanese system and learn to make their appearance. After making it, compare and test the air volume, wind pressure, noise and other data, and improve to the fan blades that are similar to theirs, and then match our own. Circuits, circuits, we don’t have a big problem, generally we can achieve good results. There is no problem with the circuit, and the fan blades are similar. The final finished cooling fan is the same as the Japanese one, but it is almost impossible to exceed their quality.
