NOVELTY - A power switch cabinet comprises a housing, through hole(s), a support, a mirror, a transparent window, heat-absorbing sheet(s), a temperature sensor connected with a circuit board, a display device, an air outlet, a blower and a flashing plate. The housing is prepared from e.g. 22 pts. wt. graphene, 27.5 pts. wt. silica gel, 25 pts. wt. quartz sand, 20 pts. wt. styrene, 19 pts. wt. polypropylene, 31 pts. wt. kaolin, 22 pts. wt. phenolic resin, 19 pts. wt. zinc oxide, 18 pts. wt. stearic acid, 34 pts. wt. carbon fiber, 19 pts. wt. copper and 13 pts. wt. methyl ethyl ketone. USE - Power switch cabinet (claimed). ADVANTAGE - The power switch cabinet has simple design, and excellent durability and cooling effect. DETAILED DESCRIPTION - A power switch cabinet comprises a housing, through hole(s) provided on the inner wall of the housing, a support provided on the bottom of the housing, a mirror provided on the support, a transparent window provided on the side wall of the bottom of the housing, heat-absorbing sheet(s) provided inside the housing, a temperature sensor connected with a circuit board, a display device provided on the outer surface of the housing, an air outlet provided at the top of housing, a blower provided in the air outlet, and a flashing plate provided on the above of air outlet. The display device is connected with the circuit board. The temperature sensor is provided with a wireless transmitter. The display device is provided with a waterproof membrane. The blower is connected with a solar panel. The housing is prepared by adding 22 pts. wt. graphene, 27.5 pts. wt. silica gel and 25 pts. wt. quartz sand to a jet mill, stirring, injection-molding, obtaining particles, adding 20 pts. wt. styrene and 19 pts. wt. polypropylene to the particles, stirring, heating to 60 degrees C, obtaining material (A), calcining 31 pts. wt. kaolin at 700-800 degrees C, heating at rate of 10 degrees C/minute, further calcining at 800 degrees C for 2 hours, naturally cooling, obtaining material (B), adding 22 pts. wt. phenolic resin, 19 pts. wt. zinc oxide and 18 pts. wt. stearic acid to a melting furnace, heating at 550 degrees C for 4 hours, obtaining material (C), adding 34 pts. wt. carbon fiber, 21 pts. wt. aluminum and 19 pts. wt. copper to a steelmaking furnace, heating at 1100 degrees C for 2.5 hours, mixing molten material with material (A), material (B) and material (C), adding 15 pts. wt. magnesium bicarbonate, 18 pts. wt. diphenyl ether and 13 pts. wt. methyl ethyl ketone, stirring, adding resultant molten mixture to an injection mold, curing for 36 hours, demolding, and curing at room temperature for 5 days.
