Latest Patents
Qiu Yang Zhang holds a patent for a cooling fan module designed for heat exchangers. This module features a motor, a fan driven by the motor, and a speed controller that connects the motor to a power supply. The speed controller operates in both high-speed and low-speed modes, utilizing a unique configuration that includes a high-speed branch and a low-speed branch connected in parallel. The low-speed branch incorporates a pulse width modulation circuit that reduces average voltage by a fixed duty ratio, allowing for low-speed operation of the motor. This design eliminates the need for a conventional voltage dropping resistor, thereby reducing power consumption and increasing the efficiency of the module during low-speed operation.
