Power cabinet heat dissipation device based on centrifugal force principle

Abstract

The invention relates to the technical field of power cabinets. The invention further discloses a power cabinet heat dissipation device based on the centrifugal force principle. The device comprises acabinet body; an air outlet is formed in the side surface of the cabinet body; an electromagnet is fixedly connected with the interior of the air outlet; a sealing plate is hinged to the interior ofthe air outlet; the exterior of the sealing plate is fixedly connected with a permanent magnet; a ventilating duct is formed in the cabinet body; a motor is fixedly connected with the interior of thecabinet body; the top of the motor is fixedly connected with a turntable; a movable rod is hinged to the interior of the turntable. The cabinet body, the air outlet, the ventilating duct, the motor, fan blades, the air inlet and the air outlet are used in cooperation. Functional electrical elements in the cabinet body are installed in a classified mode, so that internal heat flow is effectively avoided. Wind power flows into corresponding areas through the ventilating duct, and therefore the heat dissipation effect in the cabinet body is guaranteed. Stable operation of the electrical elementsis effectively guaranteed, and the service life of the electrical elements is effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of power cabinets, in particular to a cooling device for power cabinets based on the principle of centrifugal force. Background technique [0002] The electrical appliances in life are constantly increasing, and a lot of manual labor is replaced by electronic equipment. The stability of power needs to be guaranteed by qualified equipment. Therefore, power control components, circuit protection components, power main busbar connections and power meters are usually installed in a unified cabinet. In the body, it is convenient for the maintenance and monitoring of the power engineering. Since a large amount of heat is usually generated when the power components are running, in order to ensure the normal operation and service life of the power components inside the cabinet, it is usually necessary to dissipate heat from the cabinet. [0003] However, the existing cabinets usually dissipate heat by adopting natur...

Problems solved by technology

[0003] However, the existing cabinets usually dissipate heat by adopting natural air cooling, that is, waist-shaped cooling holes are provided on the cabinet body of the power cabinet, so that the high-temperature air and low-temperature air in the internal and external spaces of the cabinet can convect and play a role. The effect of air-cooling and heat dissipation on the electrical components in the cabinet, but because the natural air-cooling heat dissipation method is affected by the environment where the power cabinet is located, the temperature of the air around the power cabinet is also relatively high in an environment where there is no wind and the distribution of heating equipment is dense. High, and the convection speed of the airflow in the space inside and outside the cabinet is relatively slow, the heat generated by the electrical components can only be circulated in the cabinet, and cannot be discharged from the cooling holes in time, so that the aging of the electrical components in the cabinet is accelerated, and serious Affect the stability and service life of the power cabinet
