Self-heat-dissipation type power cabinet

Abstract

The invention discloses a self-heat-dissipation power cabinet which comprises a cabinet body, cavities are formed in side walls of the cabinet body, sliding plugs are connected between inner walls ofthe cavities in a sealed and sliding mode, the spaces between lower end portions of the cavities and the sliding plugs are filled with evaporation liquid, and heat conduction plates are embedded in the positions, corresponding to upper end portions of the cavities, of the side walls of the cabinet body. According to the invention, the evaporation liquid, a driving mechanism and a heat dissipationcolumn body are arranged; the evaporation liquid can be used to absorb heat emitted by electric appliance elements in the electric power cabinet body during work, therefore, the evaporated liquid is vaporized to push the sliding plugs to slide, gas is pushed into a device cavity, a rotating shaft is driven to rotate by taking air pressure as driving force; and meanwhile, the evaporated liquid is in direct contact with the heat conduction plate, the cooling and liquidation are achieved, the resetting of the heat dissipation cylinder is achieved, the heat dissipation is continuously conducted onthe electric appliance elements, and the auxiliary heat dissipation and cooling effect on the electric appliance elements can be achieved through exhausting and air suction of the device cavity.

Description

technical field [0001] The invention relates to the technical field of power equipment, in particular to a self-radiating power cabinet. Background technique [0002] The power cabinet is one of the most common and important equipment in the field of basic power facilities. Its function lies in the installation of circuits and power components. There are a large number of power components installed inside the power cabinet. [0003] The structure of various circuit components inside the power cabinet is relatively complex. When the electrical components in the power distribution cabinet are in high-load working conditions, a large amount of heat will be generated. If the heat is not dissipated in time, it will cause damage to the electrical components in the cabinet. Damage, which can cause the electrical appliances supplied by the power cabinet to be unable to use normally, and cause electrical safety accidents in severe cases. [0004] The heat dissipation device of the e...

[0003] The structure of various circuit components inside the power cabinet is relatively complex. When the electrical components in the power distribution cabinet are in high-load working conditions, a large amount of heat will be generated. If the heat is not dissipated in time, it will cause damage to the electrical components in the cabinet. damage, which can cause the electrical appliances supplied by the power cabinet to be unable to use normally, and cause electrical safety accidents in severe cases

[0004] The heat dissipation device of the existing power cabinet is generally provided with a heat dissipation groove on the side wall of the power cabinet, and then equipped with a heat dissipation fan for ventilation and heat dissipation, but in order to prevent sundries or water stains from entering the cabinet, the area of ​​the heat dissipation groove is generally small, which means As a result, the ventilation effect is not good, and the existing cooling fans generally require the operator to manually switch, which is not only time-consuming and troublesome, but also if the operator is slightly negligent and fails to turn on the cooling fan in time, it may cause the power cabinet to dissipate heat in time, thereby causing bad Consequences, and the motor part of the cooling fan will also generate a certain amount of heat when it is working, and the cooling effect is not ideal
