Problems solved by technology

Therefore, in a structure in which one side and the other side of the n-type thermoelectric conversion element and the p-type thermoelectric conversion element are joined to a single insulating plate as in the past, due to the difference in the thermal expansion coefficients of the n-type thermoelectric conversion element and the p-type thermoelectric conversion element, Different, there is a possibility that one of the thermoelectric conversion elements is peeled off from the insulating plate or the element is damaged

Abstract

A thermoelectric conversion module according to the present invention is characterized in that: an n-type thermoelectric conversion element and a p-type thermoelectric conversion element are configured from materials having mutually different thermal expansion coefficients; one surface side of the n-type thermoelectric conversion element and one surface side of the p-type thermoelectric conversionelement are aligned and joined to one surface side of a shared insulating substrate; and a heat conducting member is independently and individually formed on the other surface side of the n-type thermoelectric conversion element and on the other surface side of the p-type thermoelectric conversion element.

Description

technical field [0001] The invention relates to a thermoelectric conversion module formed by electrically connecting a plurality of thermoelectric conversion elements. [0002] This application claims priority based on the patent application No. 2016-060866 filed in Japan on March 24, 2016 and the patent application No. 2017-033837 filed in Japan on February 24, 2017, and the contents thereof are incorporated herein. Background technique [0003] The thermoelectric conversion element is an electronic element capable of mutual conversion of heat and electricity called Seebeck effect or Peltier effect. The Seebeck effect is an effect of converting thermal energy into electrical energy, and is a phenomenon in which an electromotive force is generated when a temperature difference occurs between both ends of a thermoelectric conversion material. This electromotive force is determined by the characteristics of the thermoelectric conversion material. In recent years, development...
