Application of DC cooling fan in various fields
Cooling fans are generally used in printers, fax machines, banner machines, medical equipment, automotive electronics, power equipment, electric vehicle chargers, communication/communication cabinets, frequency converters, transformers, industrial control equipment, stage lighting (light source cooling), new energy ( Cooling fans are required for equipment such as batteries into cabinets), engine cooling, instruments and meters.
DC cooling fans have a wide range of applications, but cooling fans are generally installed inside the machine. Now, most devices will generate heat after running, and they need cooling fans to dissipate heat. The application of cooling fans in various fields is described in detail below.

The following is an example of the application of automobile cooling fans in automobiles
The replacement of automobiles clearly marks the changes of this era, and each generation of changes has higher and higher requirements for heat dissipation. From the initial heat dissipation, to the need to reduce noise while satisfying heat dissipation, and then to develop, not only reduce noise and heat dissipation, but also need to be able to control heat dissipation in real time, that is, to support PWM intelligence fan speed regulation cooling fans.
· During the operation of the car, heat is continuously generated, and the components around the combustion chamber (cylinder liners, cylinder heads, valves, etc.) must be properly cooled. The automobile cooling system is composed of radiator, thermostat, water pump, Communications,cylinder water channel, cylinder head water channel, fan, etc. The radiator is responsible for th,e cooling of circulating water. Its water pipes and heat sinks are mostly made of aluminum materials. The aluminum water pipes are made of flat shape, and the heat sinks are corrugated. The heat dissipation performance should be taken into account. The installation direction is perpendicular to the air activity direction. It is possible to achieve smaller wind resistance and higher cooling efficiency.
·
The coolant flows inside the radiator core and the air passes outside the radiator core. The hot coolant is cooled by dissipating heat to the air, and the cold air is warmed by receiving heat from the coolant, so the radiator is a heat exchanger. The cooling fan is installed in the radiator to blow away the heat in time to achieve the whole cooling effect.
