Embodiment Construction
[0007] as attached figure 1 As shown, the shape of the present invention is a sheet-shaped body 1 spliced by semiconductor refrigeration sheets. Its heating surface is attached to the inner wall 3 of the metal shell of the high-voltage power distribution cabinet through heat-conducting silicone grease 2. Its cooling surface is tightly closed. A layer of metal film 4 is pasted. The outer surface of the metal film 4 is a polished plane, and an inclined bus bar 5 is arranged on the plane. The bus bar 5 leads to the outside of the high-voltage power distribution cabinet through the return water pipe 6 .
[0008] The semiconductor refrigeration sheet is a commercially available product. When in use, according to the size of the inner wall of the metal shell of the high-voltage power distribution cabinet, the semiconductor refrigeration chips are combined in series and parallel to form a large flat plate. The DC power supply for power supply selects standard products according to...
