Incorrect installation of the cooling fan of the inverter will also cause noise
The noise problem of the inverter cooling fan is a common problem. Some are the quality of the inverter cooling fan itself, and some are the installation problems of the inverter cooling fan. Therefore, it is also very important to install the inverter cooling fan correctly. Cooling fan 1. The installation method of clamping the frame of the cooling fan up and down is easy to produce resonance and amplify the sound due to the vibration of the cooling fan when it is running. It is impossible for the high-speed inverter cooling fan to have no vibration. 2. Adopt the method of inverted installation, the fan blades face down and absorb heat from bottom to top. The oil-contained cooling fan may exceed the height of the outer frame due to the gravity of the fan blade itself, and hit the heat sink below, causing Noise (change to double ball bearing can be solved well) 3. Incorrect installation of the lock screw, the first screw is too strong, the lock is very tight, and the parallel second screw is also locked very tight, and then lock again The two screws on the opposite side will cause the outer frame of the fan to be deformed and twisted, and the fan blade may touch the outer frame wall and produce a scratching sound. The correct thing is to lock the first screw down and tighten it. Don’t lock it out of shape, then lock the diagonal screws when finished, and then lock the other set of diagonal screws. Well, the above is the relevant knowledge of inverter cooling fan brought to you by the editor of Tongchi today. Want to know more, welcome to visit the official website of the inverter cooling fan.
