Power distribution cabinet dehumidification system based on semiconductor cooling plates

Abstract

The invention discloses a dehumidification system for a power distribution cabinet based on a semiconductor refrigerating sheet. and the hot end, the cold end is connected to the hot end; the heat pipe is arranged on both sides of the cold end and the hot end; the fins are arranged side by side on both sides of the heat pipe; the dehumidification system also includes changing the A fan for air circulation inside and outside the cabinet and a channel for heat and humidity exchange in the cabinet; the cold end and the hot end are used for the conversion of the cold end and the hot end by changing the direct current direction of the semiconductor refrigeration sheet; the invention has simple structure, high efficiency, and low energy consumption. Low power consumption, safe and convenient, easy to control; it can fundamentally solve the problem of condensation in the power distribution cabinet, and achieve the purpose of dehumidification and energy saving.

Description

technical field [0001] The invention relates to the technical field of heating, ventilating and air conditioning, in particular to a dehumidification system for a power distribution cabinet based on semiconductor refrigeration chips. Background technique [0002] In summer, especially in the rainy season, the weather is humid and hot, and the long-term operation of the internal equipment of the power distribution cabinet will generate heat, which will eventually cause condensation in the power distribution cabinet; dew condensation is very harmful to the power distribution cabinet, and it is easy to cause the aging of the line. Reduce the insulation performance of the line, and cause more safety accidents on issues such as electricity safety and information security. In recent years, there have been more and more theoretical and experimental studies on semiconductor refrigeration at home and abroad. Because semiconductors have the advantages of simple structure, small size, ...
