AI Technical Summary

Technical Problem

In existing technologies, the winding direction of fans is fixed, which makes it impossible for fans with different airflow requirements to be used interchangeably, resulting in low production efficiency and high costs.

Method used

A fan circuit was designed that, by combining a control IC chip and a surface-mount resistor branch, can flexibly select the circuit mode according to the fan winding method, ensuring that the fan operates in the predetermined airflow direction.

Benefits of technology

This technology enables the same circuit board to be adapted to fans with different winding methods, improving production adaptability and reducing costs, while simplifying circuit design and improving system efficiency and reliability.
