Industrial DC cooling fan is an industrial grade brushed or brushless fan, it uses DC power supply, working principle based on the ampere right hand rule, through the conductor current to generate a magnetic field, with a fixed magnetic field to generate suction or repulsion, to reduce the operating temperature of electrical equipment. The inner part of the fan blade is attached with a magnet around the silicon steel sheet, and the axis part is wound by two groups of coils, and the Hall induction component is used as a synchronous detection device to control a set of circuits, so that the two groups of coils winding the axis work in turn.

The types of industrial DC cooling fans are mixed flow, axial flow and centrifugal, and the components include fan frame, fan blade, bearing, PCB control circuit and drive motor. The fan frame and blade can choose PBT raw material black, PC raw material transparent or PBT raw material white. The speed is related to the number of winding turns, wire diameter, outside diameter and bottom diameter of fan blade, blade shape and bearing used, etc. The increase of speed increases the air volume correspondingly.

Industrial DC cooling fans are widely used in computer, communication, automotive, medical and other fields to reduce equipment temperature and extend service life. In harsh environments, all-metal, high temperature, dust and moisture resistant fans are needed, and the price is relatively high.

The advantages of industrial DC cooling fans are high efficiency, low noise and long life, which are suitable for the heat dissipation requirements of various industrial equipment. Its disadvantage is that the price is higher and requires professional technicians to install and maintain.
