High heat-dissipation electrical cabinet

Abstract

The invention discloses a high heat-dissipation electrical cabinet comprising an electrical cabinet body. The electrical cabinet body is provided with a bottom plate, a left side plate, a right side plate, a back plate, a top plate and a front door, wherein the bottom plate and the top plate are double-layer hollow structure, while the back plate, the left side plate and the right side plate are double-layer hollow structure as well, and are communicated with each other. A first air inlet communicated with the interior is formed on one side face of the bottom plate. Meanwhile, the upper surface of the bottom plate is provided with an air outlet which is communicated with the air pipe and extends to the position of the inner female terminal of the cabinet body. Second air inlets are formedon the upper end surface of the left side plate and the right side plate, and a plurality of air outlet groups which are parallel to each other are provided on the inner wall of the back plate, the left side plate and the right side plate. Each air outlet group comprises a plurality of air outlets provided at intervals. The air outlets in the left side plate, the back plate and the right side plate are provided in a spiral manner. An exhaust port is formed on the top plate, wherein the upper surface of the exhaust port is communicated with the exhaust pipe, and the end of the exhaust pipe is provided with an air evacuating device. According to the high heat-dissipation electrical cabinet, a draught fan is utilized to fit a cabinet body of double-layer hollow structure.so that vortex airflow is formed in the electrical cabinet to dissipate heat in the interior, and the heat dissipation effect is improved.

Description

technical field [0001] The invention relates to an electric cabinet, in particular to a high heat dissipation electric cabinet. Background technique [0002] The electrical cabinet is a cabinet made of steel to protect the normal operation of components. Electrical cabinets are widely used in chemical industry, environmental protection industry, power system, metallurgical system, industry, nuclear power industry, fire safety monitoring, transportation industry, etc. When the electrical cabinet is working, the internal current exchange is easy to generate heat, especially the busbar is a component that is prone to heat, so the electrical cabinet with poor heat dissipation is likely to generate high temperature and cause accidents. [0003] The heat dissipation of the traditional electric control cabinet is mainly achieved by installing a cooling fan or an air conditioner on the surface of the electric control cabinet to achieve the heat dissipation of the electrical compone...

When the electrical cabinet is working, the internal current exchange is easy to generate heat, especially the busbar is a component that is prone to heat, so the electrical cabinet with poor heat dissipation is likely to generate high temperature and cause accidents

[0003] The heat dissipation of the traditional electric control cabinet is mainly achieved by installing a cooling fan or an air conditioner on the surface of the electric control cabinet to achieve the heat dissipation of the electrical components that are prone to heat in the electric control cabinet; The internal busbar structure, its high current exchange generates a lot of heat, and the mounting columns of the busbar are usually multi-faceted solid copper columns, and the busbar is installed on its surface. The heat dissipation of this structure can only be heat conduction, and the use of cooling Fans or air conditioners cool down the inside of the electric control cabinet, and then use the heat conduction of copper columns to dissipate heat from the busbars. However, this method is slow in dissipating heat and the effect is not ideal. It will still cause the electrical cabinet to malfunction, thereby affecting production.
