The high-voltage sealed power distribution cabinet comprises a cabinet which is equipped with semiconductor radiators. A cabinet instrument window is disposed on the upper opening door of the cabinet, and a cabinet operation panel and a cabinet observation window are arranged on the central opening door. Heat radiation fins are blown by an axial-flow blower fan to accelerate the heat radiation speed. Heat inside the power distribution cabinet is guided out by the heat absorption end of a semiconductor cooler to be transmitted to the heat radiation fins, and heat radiation is rapidly carried out by the heat radiation fins under the effect of the axial-flow blower fan, so that heat inside the power distribution cabinet can be continuously guided out by the semiconductor cooler to lower the temperature of the power distribution cabinet. The high-voltage sealed power distribution cabinet with a heat radiation function has the characteristics of simple structure and fine heat conduction and heat radiation effect.

Summary of the invention
In order to overcome the deficiency of above-mentioned prior art, the purpose of the utility model has been to provide a kind of high pressure sealing power distribution cabinet with heat sinking function, mainly is the high pressure sealing formula to be joined transform, and has good heat sinking function.
To achieve these goals; The technical scheme that the utility model adopts is: a kind of high pressure sealing power distribution cabinet with heat sinking function; Include rack; Rack is provided with radiator for semiconductor, and the upward-acting door of rack is provided with rack instrument form, opens the door in the rack to be provided with rack guidance panel and rack observation window.
Described employing semiconductor cooler left end is a heat absorbing end, and the right-hand member of heat absorbing end is a release end of heat, and release end of heat links to each other with the high-performance fin, and the high-performance fin links to each other with axial flow blower.
The beneficial effect of the utility model is:
Because the utility model is in the high-low voltage electric power distribution cabinet both sides, several groups of radiator for semiconductor evenly are installed, the heat of rack inside is absorbed uniformly; Semiconductor cooler is installed on the shell of body both sides, preferentially selects the reasonable position of air permeability, around the semiconductor cooler release end of heat, installs the high-performance fin additional; Accelerate the speed of semiconductor cooler heat radiation, on fin, install axial flow blower again additional, blow; Accelerate air circulation; Fin is carried out air-cooled, further accelerate the radiating rate of semiconductor cooler, through above cooling measure; Can reach the effect of heat radiation fast, the inner heat of high-low voltage electric power distribution cabinet is dispelled the heat through semiconductor cooler heat absorbing end (10), release end of heat (7), fin (9), axial flow blower (10) fast.
