Background technique

A computer, commonly known as a computer, is an electronic computing machine used for high-speed computing. It can perform numerical calculations and logical calculations. It also has the function of storage and memory. It is a modern intelligent electronic device that can run according to the program and process massive data automatically and at high speed.

The use of the computer will generate heat, and if it is not dissipated in time, the internal parts of the computer will be damaged. According to the existing patent CN204178308U, an intelligent cooling fan for a computer detects the temperature through a temperature sensor, and controls the speed of the fan blades through the processor. To achieve intelligent heat dissipation, fast or slow heat dissipation can be carried out through the speed of the fan blades, but the design of the fan impeller can only carry out small-scale heat dissipation, and the heat dissipation effect is not ideal. Therefore, we propose a computer cooling fan.
