Outdoor anti-condensation heat dissipation and dehumidification type electrical control cabinet

Abstract

The invention discloses an outdoor anti-condensation heat dissipation and dehumidification type electrical control cabinet, belonging to the field of anti-condensation electrical control cabinets. According to the invention, a condensation box with a condensation assisting ball is additionally arranged at an air inlet of a cabinet body, external air is guided into an air inducing condensation cavity formed by the condensation assisting ball and a flow guide cover, and due to the fact that a temperature difference exists between the condensation assisting ball and the air and between the flow guide cover and the air, water vapor in the air is attached to the flow guide cover and the end face of the coagulation assisting ball to be condensed and guided into a liquid storage box through arc-shaped end faces of the flow guide cover and the coagulation assisting ball; and thus, on one hand, the water vapor is effectively removed and the air is dehumidified via matching of a dehumidification cotton layer at an inner end, and on the other hand, the cooling effect on the cabinet body is improved as the air is guided into the cabinet body after making contact with the low-temperature coagulation assisting ball to be cooled. In addition, a refrigeration ball filled with a refrigerant is arranged on the inner side of the coagulation assisting ball; in a high-temperature environment, heat drainage pieces deform to guide the cooling liquid in the coagulation assisting ball into the refrigeration ball, the refrigerant and the cooling liquid are fused to absorb heat and refrigerate, so refrigeration effect is improved, and a temperature difference is increased to facilitate 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 ...

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.
