A compressor cooling fan is a device used to dissipate heat and reduce operating temperatures, usually in air conditioners, refrigerators, freezers and other equipment. A compressor is a device that compresses and converts air. The heat generated during the work of the rotor and coils causes the temperature of the compressor to rise, which may lead to damage to the equipment if the heat is not dissipated in time.

The main function of the compressor cooling fan is to reduce the temperature of the compressor by taking away the heat generated by the compressor through air flow. A cooling fan usually consists of a motor, fan blades and a housing. The motor drives the fan blades to rotate, drawing air in and dissipating it through the heat sink. The heat sink is usually made of aluminium or copper and has good heat dissipation properties.

Compressor cooling fan sizes and dimensions vary from unit to unit. Some common sizes include 12V, 24V, 36V, etc. for different equipment. The size of the fan also affects the cooling effect; generally speaking, the larger the size, the better the cooling effect.

Compressor cooling fans work by rotating the fan blades driven by a motor, which draws air in and dissipates it through a heat sink. Heat sinks are usually made of aluminium or copper and have good heat dissipation properties. When air passes through the fins, it carries away heat, thus lowering the temperature of the compressor.
