Feb 05, 2025
The cooling fan is one of the types of fans. The fan specifications range from 8mm to 280mm, the voltages are 5V, 12V, 24V, 48V, 110V, 220V, 380V, and the shapes are square, round, olive, etc.
The working principle of the cooling fan is based on energy conversion, that is: electrical energy → electromagnetic energy → mechanical energy → kinetic energy. Its circuit principle is generally divided into many forms, and the performance of the fan will be different depending on the circuit used.
