Abstract
The utility model relates to a portable semiconductor cooling and heating device. The utility model is characterized in that one face of a semiconductor refrigeration electric pile is contacted with a metal disk, and the other side is contacted with a radiator, and other non-contact parts are provided with heat insulating material; the metal disk is provided with at least one refrigeration stick, one end of the radiator is provided with a miniature blower fan which is fixed on a top cover provided with ventilation holes, a compressing spring is arranged between the top cover and the radiator, and the metal disk and the top cover are fastened together through screw bolts. The utility model has the characteristics of simple structure, small size, convenient operation, and high refrigeration speed.
Description
The utility model relates to a kind of semiconductor refrigerating field, particularly a kind of portable semiconductor cold-hot machine.
The conventional semiconductor cold-hot machine mainly contains semiconductor cooling-heating box, semiconductor cold-hot cup, owing to be to liquid indirect refrigeration and heating by casing and cup, have structural defective, refrigeration speed is slow, and the refrigeration time is long, and power consumption is many, and volume is big, is inconvenient to carry.
The purpose of this utility model is to overcome the problem that exists in the existing semiconductor cold-hot device, provides a kind of volume little, simple in structure, and refrigeration speed is fast, and is easy to use, the micro semiconductor cold-hot machine of being convenient to carry.
Task of the present utility model is to realize like this, conductor refrigeration pile one side is touched mutually with the metal disc, another side touches mutually with radiator, all the other noncontact portions are provided with heat-insulating material, at least be equiped with a refrigeration rod on the metal disc, be provided with miniature fan in sink side, blower fan is fixed on the top cover that has ventilation, be provided with holddown spring between top cover and radiator, metal disc and top cover are by bolted together.During use, in the refrigeration rod insertion liquid with the portable semiconductor cold-hot machine, connect dc source and get final product, when selecting refrigeration or heating, as long as the polarity of change dc source.
The utility model is simple in structure, volume is little, easy to use, refrigeration is fast, convenient carrying.
Below in conjunction with legend the utility model is described further:
Fig. 1 portable semiconductor cold-hot machine structural representation.
With reference to Fig. 1, the refrigeration end face of conductor refrigeration pile (TEC1-12705) 5 touches mutually with the inner face of the metal disc 2 that has a metal refrigeration rod 3, the heat release end face touches mutually with radiator 7, all scribble heat-conducting silicone grease layer 6 between its contact-making surface, and be provided with holddown spring 8 at top cover 14 and 7 in radiator, guarantee that contact is good, in order to the heat transmission, for cutting off cold and hot exchange, 5 all the other the noncontact portions of pushing away at the refrigeration electricity are filled with heat-insulating material 9, mini fan 11 is housed above radiator 7, blower fan 11 is fixed on the top cover 14 by screw 12, offer air vent 13 on the top cover 14, be provided with heat insulating mattress 16 between top cover 14 and the metal disc 2, and adopt nylon bolt 15 to tighten together.For strengthening exchange heat, can on metal disc 2, weld several metal refrigeration rods 3, but be unfavorable for cleaning too much.Conductor refrigeration pile 5 is to work under the dc source environment, so blower fan 11 is also selected dc fan for use, its power line 17 is connected dc source get final product work, change dc source input polarity, can make the hot and cold end face of conductor refrigeration heap 5 produce exchange, also be that refrigeration rod 3 also can be used to heating liquid.
Claims (3)
