The invention provides a heat recovery electric card device, which includes an upper electric snap ring supported by a central axis and a lower electric snap ring supported by a support shaft. The upper and lower electric snap rings are stacked, wherein: the upper and lower electric snap rings are opposite The rotary contact includes high electric field area and low electric field area separated by spacers respectively, wherein the high electric field area and the low electric field area in the upper and lower electrical snap rings are arranged opposite to each other and a hot end and a cold end are formed by applying power, The hot end and the cold end are respectively in contact with a heat load, and a low heat conduction layer is provided between the two heat loads to prevent heat loss. Through the combination of the above-mentioned structure and structure, the technical problems of heat recovery, energy saving, and environmental protection are solved. , achieving good effects of simple process, improved refrigeration power and efficiency, energy saving and environmental protection.
Description
technical field [0001] The invention provides a heat recovery electric card refrigeration device, in particular to a heat recovery electric card refrigeration device made of a rotatable electric card material ring. Background technique [0002] Typically, climate conditioning equipment such as heat pumps, refrigerators, and air conditioners is cooled by a mechanical vapor compression cycle. This kind of refrigeration system is not only inefficient, but also consumes a lot of energy, and the gases that produce the greenhouse effect have a great impact on the environment. Climate-conditioning equipment that improves energy efficiency, reduces costs, and protects the environment has become a new topic of business research. [0003] The electrical card effect is a result of the direct coupling between thermal properties (such as entropy and temperature) and electrical properties (such as electric field and polarization) of insulating dielectric materials. In this type of mater...
