Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Referring to accompanying drawing 1 and accompanying drawing 2, the utility model comprises first shell 1 and second shell 8 that is fixed together with first shell 1, first shell, 1 volume ratio, second shell 8 is big, first shell 1 is installed on electrical equipment rack 10 outsides when wherein using, second shell 8 is installed on electrical equipment rack 10 inside, is provided with blow vent 13 and drainage pipe 11 in the bottom of second shell 8; In the space that first shell 1 and second shell 8 are constituted, from left to right be fixed with blower tray 3, fin 4, thermal insulation board 5 and condensate film 7 successively by screw; Described blower tray 3 left sides offer installing hole, fan 2 is installed in this installing hole, be embedded with two semiconductor chilling plate 6(in the described thermal insulation board 5 and select the number of installing as required), the cold junction of described semiconductor chilling plate 6 is pasted on condensate film 7 backs, the hot junction is pasted on fin 4 backs.Described condensate film 7 is installed in the air flows and the air flows between isolated cold junction and the hot junction.
During making, it is TEC-12 type paltie effect chip that semiconductor chilling plate 6 can adopt model, area is 50 ㎜ * 50 ㎜, or the TEC series semiconductor cooling piece of day electronics joint stock partnership company production in Wei County, or the TEC112706 N-type semiconductor N cooling piece of Changshan County ten thousand paddy electronics technology Co., Ltds production.Thermal insulation board 5 materials are Fu Lesi (FLEX) insulating rubber plastic.
Humid air in the electrical equipment rack 10 is being discharged this dehumidifier through cryogenic condensation sheet 7 dehumidifying backs, and airborne water vapour condenses on condensate film 7 after drainage pipe 11 is discharged.The cold air in hot junction is sucked by fan 2 and fin 4 is lowered the temperature to improve the operating efficiency of electronic chip 6.Separated to stop air flows by thermal insulation board 5 between cold junction and the hot junction, can avoid the air quantity of the inside wind regime of electrical equipment rack 10 to leak on the one hand, can avoid the cold junction that air flows causes and the exchange heat in hot junction on the other hand, the air of the inside of electrical equipment rack 10 constitutes air circulation through air channel 9, and the air in the circulation is dehumidified through this dehumidifier.
