Example Embodiment
[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.
[0024] refer to Figure 1-8 , a closed type power distribution cabinet high-frequency anti-aging cooling device, including a power distribution cabinet 1, the inner side of the power distribution cabinet 1 is fixed with an L-shaped heat-absorbing frame 2, and one side of the L-shaped heat-absorbing frame 2 is fixed with a number of heat-absorbing frames. Heat fins 3, one side of the L-shaped heat-absorbing frame 2 are fixed with a heat-conducting plate 4, so that it has an automatic heat-absorbing function. When in use, electrical components can be installed on the surface of the L-shaped heat-absorbing frame 2, and the power distribution cabinet 1 The heat above wil...

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...
