There are two key methods of heat dissipation for DC cooling fans. One is to use side suction for DC cooling fans.

The DC cooling fan blowing type is to point the cooling fan to the pyrogen and blow it violently. It sucks the strong cold air from the outside to replace the warm air inside, so that the heat does not need to be continuously concentrated in the pyrogen, and is dissipated into the pyrogen. All around, it's a quick way to get rid of heat. This method can remove heat faster, but the application life of the cooling fan will be shorter, because a large amount of dust will be digested and absorbed.

The air intake type of the DC cooling fan is just the reverse. It discharges the heat through the hot cyclone inside the cooling fan to the outside, and the other enters the strong cold air. Air, the actual effect of this type of heat removal is less, and the service life of the DC cooling fan will be longer.

Whether the larger the blade of the DC cooling fan is, the greater the exhaust air volume is. It is a problem that customers often ask. In fact, it is not. The exhaust air volume of the DC cooling fan is related to the number of fan blades, but it is not a one-to-one relationship. 

If the DC cooling fan adds two fan blades, the wind will become larger, then there is no way for everyone to think about the lack of better exhaust air. It is enough to add two blades immediately. The exhaust air volume of the DC cooling fan It is closely related to the shape, viewing angle, and length of the fan blades, and naturally it is also related to the total number of fan blades.

The DC cooling fan has the characteristics of long operating life, low vibration and low noise. With the change of application conditions and working temperature, sometimes different speed ratio electric fans are required to satisfy the requirements.
