An outdoor anti-condensation heat dissipation and dehumidification electrical control cabinet

Abstract

The invention discloses an outdoor anti-condensation heat dissipation and dehumidification electric control cabinet, which belongs to the field of anti-condensation electric control cabinets. By adding a condensation box with coagulation-assisting balls at the air inlet of the cabinet, the outside air is introduced into the anti-condensation aid At the air induction condensation cavity formed by the ball and the deflector, due to the temperature difference between the coagulation aid ball, the deflector cover and the air, the water vapor in the air adheres to the deflector, the end surface of the coagulation aid ball and condenses, and passes through both. The arc-shaped end surface is introduced into the liquid storage tank. On the one hand, it can effectively remove water vapor, and cooperate with the dehumidification cotton layer at the inner end to dehumidify the air. The cooling effect of the cabinet body, in addition, a cooling ball filled with refrigerant is installed inside the coagulation-assisting ball. Combined with endothermic refrigeration, it not only improves the cooling effect, but also increases the temperature difference to help pre-condensation.

Description

technical field [0001] The invention relates to the field of electrical control cabinets, more specifically, to an outdoor anti-condensation heat dissipation and dehumidification electrical control cabinet. Background technique [0002] The electrical control cabinet is to assemble switchgear, measuring instruments, protective appliances and auxiliary equipment in a closed or semi-closed metal cabinet or on a screen width according to the wiring requirements. and the safety of surrounding equipment. During normal operation, the circuit can be connected or disconnected by manual or automatic switch, and the circuit can be cut off or alarmed by means of protective electrical appliances in case of failure or abnormal operation. Various parameters in operation can be displayed by means of measuring instruments, and some electrical parameters can also be adjusted. , to prompt or signal the deviation from the normal working state. It will generate a lot of heat during long-term ...

AI Technical Summary

Problems solved by technology

It will generate a lot of heat during long-term operation, especially for products with frequency converters, which will generate more heat, and it is easy to make the internal temperature of the electrical control cabinet reach more than 40 degrees, and the components themselves are also very sensitive to high temperatures. Sensitive, once the temperature inside the electrical control cabinet is higher than 40°C for a long time, it will seriously affect the operation stability and service life of our power distribution equipment

[0003] Existing electrical control cabinets generally take heat dissipation measures, the most common is to set cooling holes that communicate with the outside world, but because outdoor electrical control cabinets are exposed to the natural environment, moisture in the outside air will enter the electrical control cabinet, resulting in The humidity in the cabinet is high. At the same time, in high temperature weather, the air humidity is high. Due to the large temperature difference between the electrical control cabinet and the external environment, the moisture in the air is easy to condense into dew on the surface of the electrical components and gather into water droplets. To a certain extent, it will cause corrosion to the electrical components in the cabinet, which will easily cause problems such as circuit short circuit and electric leakage.
