The humid air is sucked into the machine by the fan and passes through the heat exchanger. At this time, the water molecules in the air are condensed into water droplets, and the treated dry air is discharged outside the machine. This cycle keeps the indoor humidity at a suitable relative humidity.

A humidity sensor is arranged outside the box, and an MCU is arranged in the program control board. The humidity sensor is connected to the program control board, the program control board is connected to the fan, and the cooling condenser is connected to the program control board.

The external power supply is directly connected to the power plug.

The utility model is characterized by: the overall structure of the utility model is simple, there is no need to debug the device before installation, it can be installed directly, which is convenient for installation and operation; because the control board works according to the model issued by the sensor, and the sensor is used for a long time In the air, the temperature and humidity of the air are collected at any time and converted into models, allowing the device to perform intermittent work according to the temperature and humidity of the surrounding air.

The utility model has the following advantages:

1) Through the utility model, the dehumidifier of the power cabinet can be directly connected with the plug to make the device work.

2) The utility model can realize the temperature and humidity balance in the power equipment within a certain interval index.
