A cooling fan is a device specifically designed to reduce the temperature of electronic equipment, commonly found in computers, cell phones, servers, and other electronic equipment, with the purpose of reducing the temperature of circuit boards and electronic components to ensure normal and stable operation of the equipment. A cooling fan usually consists of components such as a motor, fan blades, heat sinks and accessories.

The motor is the core component of a cooling fan and is mainly composed of a driver and a rotor. The driver is responsible for providing power, and the rotor is responsible for driving the fan blade to rotate. The fan blades are the main components of the cooling fan, and their number and thickness affect the air pressure and airflow, as well as the inlet angle. The heat sink is an important part of the cooling fan, its size affects the cooling performance, but improper design may affect the cooling ability.

Accessories for cooling fans include power cords, control switches, speed controllers, etc., which are used to connect the cooling fan to the power supply and to control the speed and airflow of the cooling fan.

The working principle of the cooling fan is to drive the fan blades to rotate through the motor to draw air into the heat sink, and then through the heat sink to emit heat into the surrounding environment. The performance of a cooling fan depends on factors such as the speed of the motor, the number and thickness of the fan blades, the size and design of the fins, and the quality of the accessories.

Cooling fans are used in a wide range of applications, including computers, cell phones, servers, automobiles, home appliances, and other fields. In electronic devices such as computers and cell phones, cooling fans are essential components that can effectively reduce the temperature of the device and extend its service life. In automobiles and home appliances and other fields, cooling fans are also widely used to improve the reliability and stability of the equipment.
