Can AC cooling fan be used for electric cabinet? What hidden dangers will exist?

Can the AC cooling fan be used in the electric cabinet?

The electrical cabinet box, also known as the control box, is usually equipped with electrical equipment, such as circuit connection, control panel, safety protection, etc. With the improvement of electrical safety, in addition to heat dissipation equipment, electrical cabinets and boxes will be more intelligent and integrated. AC cooling fan, also known as AC fan, is mainly used to cool various equipment. In addition to smart home appliances, transportation, aerospace and manufacturing equipment industries, you can also use electrical cabinets, cabinets, power distribution cabinets and battery forming cabinets.

The AC fan is driven by the AC power supply, and the voltage will change positively or negatively. It is completely independent of circuit control and generates magnetic fields. The power frequency is constant, and the change speed of magnetic pole generated by silicon chip is determined by the power frequency. The higher the frequency, the faster the switching speed of the magnetic field theoretically, and the faster the speed will be. The electric cabinet can use AC cooling fan, and the electric cabinet can also use DC cooling fan. To be exact, whether to use AC or DC depends on the voltage provided by the cooling fan equipment, because each cooling fan size has DC and AC, and the electrical cabinet box only needs to determine the air volume and reserved size.
