Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

As shown in Figure 1, the transducer air conditioning heat abstractor that the utility model provides comprises radiator 1 and semiconductor chilling plate 2, and the automatically controlled plate 3 of the off-premises station that is connected with radiator 1.The hot junction of semiconductor chilling plate 2 closely is fitted in by heat-conducting silicone grease in the groove of radiator 1 base and (indicates among the heat conductive silica gel figure between described semiconductor chilling plate and the radiator), heat-conducting silicone grease is used for the space of filling semiconductor cooling piece 2 and radiator 1 contact-making surface making the contact heat resistance minimum.The cold junction of the automatically controlled plate of off-premises station 3 and semiconductor chilling plate 2 closely fits together by heat-conducting silicone grease (among the figure sign), and heat-conducting silicone grease is used for the space of filling semiconductor cooling piece and automatically controlled plate 3 contact-making surfaces of off-premises station making the contact heat resistance minimum.With screw with on automatically controlled plate 3 of off-premises station and semiconductor chilling plate 2 fixed heat sink 1 base.The degree of depth of the groove of radiator 1 base is 2mm, can make semiconductor chilling plate 2 not be shifted, fix easily, and can guarantee again has more space between automatically controlled plate 3 of off-premises station and the radiator 1.

Fig. 2 is the semiconductor refrigerating principle schematic.P type semiconductor and N type semiconductor material clip form path (claim thermoelectric to) between metal plate, outside under the effect of electric field, P type semiconductor at a point place the hole, need absorb certain heat from sheet metal, in order to improve the potential energy of self, just can enter in the P type semiconductor, so this some place temperature can reduce the formation cold junction; And in the hole at b point place, on the contrary, need discharge unnecessary energy just can enter in the sheet metal, at this moment this temperature raises, and forms hot junction.And be that free electron flows in N type semiconductor, the direction of it and hole flow is opposite, absorbs heat at c point place just can enter in the N type semiconductor, emits heat at d point place and just can enter into sheet metal.Therefore can absorb extraneous heat refrigeration here at a, c, become cold junction; And b, d have the unnecessary heat of release here, become the hot junction.

Fig. 3 is the heat spreader structures schematic diagram of the utility model transducer air conditioning heat abstractor.Radiator is made up of heat dissipation base 14 and some radiating fins 15.Heat dissipation base 14 central authorities are provided with a rectangular groove 13, and the length of groove 13 and wide size according to semiconductor chilling plate are decided, and the degree of depth is 2mm; Heat dissipation base 14 is provided with six automatically controlled plate mounting screw holes 12, and decide according to the screw hole location on the automatically controlled plate its position, hole; Heat dissipation base 14 also is provided with six electric-controlled box mounting screw holes 11, and decide together according to the screw hole location of electric-controlled box its position, hole, and above-mentioned screw hole can increase or reduce according to actual needs.
