Abstract
The invention discloses a heat radiation method of a closed rectification power supply device. An inner circulation air channel with an upper opening and a lower opening is arranged in the cabinet body of the closed rectification power supply device. An outer circulation air channel is formed between the inner circulation air channel and the inner wall of the cabinet body. The upper opening and the lower opening of the inner circulation air channel are communicated with the outer circulation air channel, wherein the rectification unit of the rectification power supply device is arranged in the inner circulation air channel. After hot air in the outer circulation air channel is cooled to cold air through heat exchange with water or air, the cold air is introduced through an air inlet at the lower end of the inner circulation air channel. The cold air absorbs the heat of the rectification unit in the inner circulation air channel and becomes hot air. Then the hot air is discharged out of the outer circulation air channel through an air outlet at the upper end of the inner circulation air channel, thereby finishing circulation. The heat radiation method of the closed rectification power supply device has advantages of simple operation, high heat radiation effect, insulation between water and electrical appliances, high suitability for various adverse environments, etc.
