High-frequency anti-aging cooling device of closed power distribution cabinet

Abstract

The invention relates to the technical field of power distribution cabinets, in particular to a high-frequency anti-aging cooling device of a closed power distribution cabinet. The device comprises apower distribution cabinet, an L-shaped heat absorption frame fixedly arranged on the inner side of the power distribution cabinet, a plurality of heat absorption fins fixedly arranged on one side ofthe L-shaped heat absorption frame, and a heat conduction plate fixedly arranged on one side of the L-shaped heat absorption frame and fixedly connected to the inner side of the power distribution cabinet. A cooling liquid box is fixedly arranged on one side of the power distribution cabinet, a plurality of evenly-distributed through holes are formed in one side of the power distribution cabinet,heat conduction columns are fixedly arranged on the inner sides of the through holes, ends of the heat conduction columns are fixedly connected to one side of the heat conduction plate, a plurality ofthrough holes are formed in the two sides away from the cooling liquid box, and the heat conduction columns are fixedly connected to the inner sides of the through holes. By arranging the L-shaped heat absorption frame, the heat absorption fins, the heat conduction columns, a heat dissipation plate, the heat dissipation fins, a heat dissipation fan A and a second heat dissipation device, the device has the functions of being dustproof, waterproof, convenient to clean, capable of achieving dual heat dissipation and cooling and the like.

Description

technical field [0001] The invention relates to the technical field of power distribution cabinets, in particular to a high-frequency anti-aging cooling device for a closed power distribution cabinet. Background technique [0002] The power distribution cabinet (box) is divided into power distribution cabinet (box), lighting distribution cabinet (box), metering cabinet (box), and is the final equipment of the power distribution system. The cabinet is used in the occasions where the load is scattered and there are few circuits; the motor control center is used in the occasions where the load is concentrated and there are many circuits. Most of the power distribution cabinets in the prior art use fans to exchange the air inside the power distribution cabinet with the outside to Realize heat dissipation and cooling. This heat dissipation and cooling method is relatively simple and has no dust-proof function. External dust will enter the interior of the power distribution cabine...

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem in the prior art that most of the power distribution cabinets in the prior art use fans to exchange the air inside the power distribution cabinet with the outside to achieve heat dissipation and cooling. Dust function, the external dust will enter the inside of the power distribution cabinet, which is not easy to clean, and will accelerate the aging of the electrical components inside the power distribution cabinet, resulting in the shortcoming of its low service life, and the proposed closed power distribution cabinet is high Frequency anti-aging cooling device
