AI Technical Summary
Technical Problem
In existing semiconductor dehumidification devices, cold-end air and hot-end air interfere with each other, resulting in low dehumidification efficiency.
Method used
By using an air duct cover to separate the cooling components and the heat dissipation components, an independent airflow path is formed, allowing the air to flow in one direction, avoiding mutual interference between the cold and hot ends of the air, and improving dehumidification efficiency.
Benefits of technology
By using an independent airflow path, the dehumidification efficiency of the switchgear is improved, ensuring that the condensation effect of the cold-end air is not affected by the temperature of the hot-end air.

Abstract
The utility model discloses a dehumidification device of a switch cabinet. The dehumidification device comprises a shell and a semiconductor dehumidification assembly arranged in the shell. The shell is provided with at least one air inlet area and at least one air outlet area; the semiconductor dehumidification assembly comprises a semiconductor chilling plate, a refrigeration piece, a heat dissipation piece, an air duct cover and a fan, the refrigeration piece and the heat dissipation piece are installed at the cold end and the hot end of the semiconductor chilling plate respectively, the air duct cover is connected with the semiconductor chilling plate and separates the refrigeration piece from the heat dissipation piece, and an air outlet cavity covering the heat dissipation piece is formed in the air duct cover; the air outlet cavity is provided with an air inlet and at least one air outlet, all the air outlets of the air outlet cavity are in butt joint with all the air outlet areas of the shell respectively, an air inlet cavity communicated with the air inlet areas of the shell is formed between the air duct cover and the shell, and the air inlet of the air outlet cavity is communicated with the air inlet cavity. The fan is connected with the air duct cover and used for driving air in the air inlet cavity to enter the air outlet cavity from the air inlet of the air outlet cavity. The dehumidification device has the advantage of being high in dehumidification efficiency.
