Description
High-effective thermoelectric refrigerating equipment belongs to the refrigerating plant of answering electricity consumption.
At present, the figure of merit of thermoelectric element equates with the figure of merit of its material, and has determined the effect of thermoelectric cooling.Therefore, in order to make the thermoelectric cooling better effects if, in the last thirty years,,, thereby reach good thermoelectric cooling effect so that make the higher thermoelectric element of figure of merit basically all at the higher thermoelectric material of research and development figure of merit.But the figure of merit of thermoelectric material still is in the level of later 1960s so far, and it is worth less than 4 * 10
-3K
-1, so the effect of thermoelectric cooling does not have much raisings yet.CN2327959Y discloses a kind of novel electron refrigerator, is made up of galvanic couple arm, brace, cold drawing and hot plate, has that thermal resistance is little, an advantage of little power consumption, efficient height, long service life.But its galvanic couple arm is exactly a thermoelectric element, and thermoelectric element equates with the figure of merit of thermoelectric material, and value is less than 4 * 10
-3K
-1So refrigeration does not have substantive the raising, so range of application is limited to.
Purpose of the present invention is to provide that a kind of cost is low, little power consumption, the temperature difference is big, refrigeration obviously improves high-effective thermoelectric refrigerating equipment.
The present invention realizes above-mentioned purpose like this.In the measures of taking on the thermoelectric element heat resistant layer to be set, to change structure and certain-length is set among thermoelectric element such as strong conductive and heat-conductive spare, the heat-conducting area that makes thermoelectric element is less than its conductive area, thereby make the figure of merit of the figure of merit of thermoelectric element greater than its thermoelectric material, the figure of merit of thermoelectric element can reach 13 * 10
-3K
-1, even higher.Along with the figure of merit of thermoelectric element increases, the thermoelectric cooling effect obviously improves, and maximum temperature difference can be higher than original more than 1 times.And then the strong conductive and heat-conductive spare that connects certain-length in the one or both ends of thermoelectric element is combined into the galvanic couple arm.Thermoelectric pile is made up of this galvanic couple arm, brace, cold drawing and hot plate.By controlling the length of strong conductive and heat-conductive spare, can adjust cold drawing and hot plate, the mutual distance of element cold junction and hot junction, reduce hot and cold amount loss as far as possible, keep best refrigeration, can save the thermoelectric material about 30% simultaneously again, thereby reduce cost.The circuit of thermocouple adopts and is connected in series in the thermoelectric pile, and heat absorption (or heat release) end adopts and is connected in parallel.Between hot and cold plate with exhausted electric heat-insulating material filling or take insulation.
For dispelling the heat better, absorbing heat, heat absorption, heat abstractor are installed on thermoelectric pile cold drawing, hot plate, fin, heat absorbing sheet, cooling water tank etc. for example are installed, constitute thermoelectric cooling device.
It is low that the present invention has a cost, little power consumption, the characteristics that the temperature difference is big, refrigeration obviously improves.The thermoelectric cooling device formed in conjunction with firmly, reliable operation, life-span be long, is applicable to that freezing, refrigeration and refrigerator, air-conditioning, water dispenser etc. make refrigeration device, also can be used for thermo-electric generation, heat pump and manufacturing thermoelectricity instrument, instrument etc.
