How to use the cooling fan correctly to extend its life?

Perform maintenance regularly, including cleaning dust and adding sewing machine lubricant to the fan shaft.
The working principle of the cooling fan: it is realized by 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.
Cooling fan, English name: Cooling fans. The technology and performance of cooling fans have fully reached a mature stage, and new technologies are constantly emerging. The fan specifications range from 8mm to, the voltage is 5V, and the shape is square, round, olive, etc.
What factors affect the life of the cooling fan?
1. Air cleanliness: Fan life is short in dusty places
2. Air temperature and humidity: Too high, too low, or too high temperature affects life
3. Current stability: Unstable voltage or excessive current affects life
4. Other factors: Human collision, etc.
How does the cooling fan work?
1. Long life, high reliability;
2. High performance, smooth operation;
3. Intelligent, mechatronic, easy to control;
4. Small size, low power consumption;
5. Low noise, no electromagnetic interference.
