[0002] A rectifier is a device that converts AC power into DC power. The rectifier has two main functions: first, it converts AC power into DC power and supplies it to the load or inverter after filtering; second, it provides charging voltage to the battery.

[0003] The rectifier will emit a very high temperature when in use. As the speed of the paper machine increases and the load rises, the temperature of the rectifier will rise linearly. High temperature is not conducive to the operation of the rectifier. Too high a temperature exceeding ℃ will cause the radiator contact surface of the rectifier to burn out. Poor heat dissipation of the rectifier will lead to unstable rectification and may even cause the rectifier to burn out and explode. The high temperature generated in normal production affects the stability of the rectifier voltage, resulting in a reduction in the service life of the rectifier and a reduction in production efficiency.
