Thermoelectric conversion module

Abstract

This thermoelectric conversion module (10) has a plurality of thermoelectric conversion elements (11), and first electrode parts (21) disposed on one end side of the thermoelectric conversion elements (11) and second electrode parts (22) disposed on the other end side of the thermoelectric conversion elements (11), the plurality of thermoelectric conversion elements (11) being electrically connected through the first electrode parts (21) and the second electrode parts (22), wherein the thermoelectric conversion elements (11) are sealed by a sealing layer (15) comprising an insulating organic material, and one surface of the first electrode parts (21) and the second electrode parts (22) is exposed from the sealing layer (15).

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 Patent Application No. 2019-048660 filed in Japan on March 15, 2019, and uses the content thereof here. Background technique [0003] A thermoelectric conversion element is an electronic element that can convert heat energy and electric energy to each other through the Seebeck effect or the Peltier effect. [0004] The Seebeck effect is a phenomenon in which an electromotive force is generated when a temperature difference is generated across a thermoelectric conversion element, converting thermal energy into electrical energy. The electromotive force generated by the Seebeck effect depends on the characteristics of the thermoelectric conversion element. In recent years, thermoelectric power generation utilizing this effect has been actively developed. [0...

AI Technical Summary

Problems solved by technology

[0020] For example, when used in a high-temperature range of 250°C or higher, organic sealing materials such as rubber or resin are thermally decomposed or deteriorated due to deterioration, so they cannot be used.

Also, since graphite is also deteriorated by oxidation in the atmosphere, it cannot be used stably

[0021] It can be used if it is a metal with a high melting point, but in the case of arranging parts made of metal, the number of parts will increase, and it may not be able to be used stably due to misalignment or falling off.

Furthermore, in the case of using a waterproof frame, etc., the size and weight increase, so it is difficult to arrange it in a narrow space, or to install it on a rotating body, etc.
