The radiator fan in the electric cabinet is very important, we know the electric appliance will give off heat, if does not carry on the radiator, easy to cause the electric appliance to overheat and the burner shortens the life, then we use the radiator fan in the electric cabinet how should choose the type? 

The cooling fan mainly considers the normal working temperature in the cabinet, the highest ambient temperature outside the cabinet, obtains a temperature difference, the fan ventilation rate, estimates the air capacity in the cabinet. Three data are known: temperature difference, air exchange rate and air capacity, then the time of air exchange in the cabinet is calculated, and the actual required air exchange rate is calculated by temperature difference, according to the protection level of equipment in the control cabinet, need to consider the control cabinet dust and moisture-proof function. 

The above is a brief introduction to the type selection of the cooling fan in the electrical cabinet. I hope it will be helpful to you. Dongxing Yue has specialized in making cooling fans for 12 years. It has a good reputation in the industry. If you need, you can compare our fans, a good cooling fan can not only maintain the normal operation of the equipment, but also improve the efficiency, want to know more about the cooling fan can pay attention to us.
