专利汇可以提供Thermoelectric effect element专利检索,专利查询,专利分析的服务。并且PURPOSE:To prevent the remarkable decrease of performance of a thermoelectric effect element due to heat transfer caused by convection and radiation of air flowing through a space between thin plates from the side of a thin plate having exothermic action to the side of a thin plate having endothermic action, by filling foaming thermal insulation material in the space between the two thin plates. CONSTITUTION:Foaming thermal insulation material 7 like rigid urethane foam and phenol foam is filled between two thin plates 2. In order to obain excellent filling property in a thin gap, reactivity of the above thermal insulation material 7 has a gel time of about 90 seconds which is slower than the general-purpose material for a refrigerator and the like by a little less than 30 seconds. Its thermal conductivity has thermal insulation property of about 0.0140 (Kcal/mhr deg.C). By filling the foaming thermal insulation material in the space between the two thin plates 2 of the thermoelectric effect element 1, the transferring quantity of heat from the side of the thin plate 2 having exothermic action to the side of the thin plate 2 having endothermic action can be remarkably reduced. By using the forming thermal insulation material 7 of the lower thermal conductivity, the performance of the thermoelectric effect element is the more improved.,下面是Thermoelectric effect element专利的具体信息内容。
