Abstract
A high-voltage sealing power distribution cabinet with a radiating function comprises a cabinet body. A semiconductor radiator is arranged on the cabinet body, a cabinet instrument window is arranged on an up-sliding door of the cabinet, a cabinet operation panel and a cabinet observation window are arranged on a middle sliding door of the cabinet body, and radiating fins are blown by an axial flow fan to accelerate radiating. When a heat absorption end of a semiconductor cooler leads out heat inside the power distribution cabinet and then transfers the heat to the radiating fins, the radiating fins rapidly radiate heat under the action of the axial flow fan, the semiconductor cooler can continuously lead out the heat inside the power distribution cabinet, the temperature of the power distribution cabinet is reduced, and the power distribution cabinet has the advantages of simple structure and fine heat conducting and radiating effects.

in the high-low voltage electric power distribution cabinet field, interior a large amount of connectors and the various electronic devices and components installed due to power distribution cabinet, and the existence of a large amount of wires is arranged, cause the total resistance value of power distribution cabinet very high, therefore directly cause high-low voltage electric power distribution cabinet in work, namely in the situation that conduction can be distributed a large amount of heats, temperature in power distribution cabinet is improved suddenly, again because electronic devices and components and the connector of power distribution cabinet inside are very high to the dustproof requirement of power distribution cabinet, therefore power distribution cabinet all adopts sealed type, reducing dust enters in power distribution cabinet, will make so the very difficult discharge power distribution cabinet of heat of the generation in high-low voltage electric power distribution cabinet, nowadays heat dissipating method commonly used be in rack, frame fills powerful axial flow blower, and offer louvre, make the wind that axial flow blower blows out form air-cooled circulation, the heat of high-low voltage electric power distribution cabinet inside is blown out body fast, reach the effect of heat radiation, but adopt this radiating mode, shortcoming is obvious: first has destroyed the sealing of high-low voltage electric power distribution cabinet, make the dust dust, also have the dust of static electrification to enter in power distribution cabinet by blower fan and louvre, circulation through blower fan is attached to various electronic devices and components, on connector or wire, directly affected the insulating properties of power distribution cabinet, even leading to short circuit causes the accident, second shortcoming is that radiating rate is slow, because general high voltage power distributing cabinet body is larger, in order to keep the sealing of rack as far as possible, the axial flow blower quantity of installing is few, and the louvre bore of cutting is little, and therefore air-cooled circulation is subject to the interior of equipment cabinet electronic devices and components, blocking of various baffle tray, lead forming many air-cooled dead angles, can't dispel the heat, so radiating effect is very poor.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the object of the present invention is to provide a kind of high pressure sealing power distribution cabinet with heat sinking function, be mainly the high pressure sealing formula to be joined transform, have good heat sinking function.
To achieve these goals, the technical solution used in the present invention is: a kind of high pressure sealing power distribution cabinet with heat sinking function, include rack, rack is provided with radiator for semiconductor, the upward-acting door of rack is provided with rack instrument form, opens the door in rack to be provided with rack guidance panel and rack observation window.
Described employing semiconductor cooler left end is heat absorbing end, and the right-hand member of heat absorbing end is release end of heat, and release end of heat is connected with the high-performance fin, and the high-performance fin is connected with axial flow blower.
The invention has the beneficial effects as follows:
due to the present invention in the high-low voltage electric power distribution cabinet both sides, several groups of radiator for semiconductor evenly are installed, heat to interior of equipment cabinet absorbs uniformly, semiconductor cooler is installed on the shell of body both sides, the reasonable position of preferential selection air permeability, install the high-performance fin additional around the semiconductor cooler release end of heat, accelerate the speed of semiconductor cooler for heat dissipation, install again axial flow blower additional on fin, blow, accelerate air circulation, carry out air-cooled to fin, further accelerate the radiating rate of semiconductor cooler, through above cooling measure, can reach fast the effect of heat radiation, make the heat of high-low voltage electric power distribution cabinet inside by semiconductor cooler heat absorbing end (10), release end of heat (7), fin (9), axial flow blower (10) dispels the heat fast.
