Problems solved by technology

As a result, uneven surface pressure is generated on the interface between the high-temperature heat source, the thermoelectric module, and the low-temperature member, depending on where the thermoelectric module is placed and the degree of tightening of the straps, which often affects the performance of the power generation device
In addition, there is no structure in which a thermoelectric module is directly connected to a low temperature component with a component extending from a high temperature heat source

Abstract

Provided is a thermoelectric generating device comprising a hot member for conducting the heat energy of a hot medium, a cold member arranged on the opposite side of the hot medium of the hot member and having a cold medium passage therein, a thermoelectric module clamped between those hot member and cold member and having a thermoelectric conversion element packaged therein for converting the heat energy due to the temperature difference between the hot medium and a cold medium to be fed to the cold medium passage, into an electric energy, and one or more tie rods for fastening the cold member and the hot member.

Description

Technical field [0001] The present invention relates to a thermoelectric power generation device that uses a thermoelectric module to convert thermal energy into electrical energy by using a temperature difference, and more particularly relates to a thermoelectric power generation device that can generate electrical energy by widely using high-temperature fluids or other types of heat sources that emit radiant heat . Background technique [0002] In recent years, with the advancement of industrial technology, the total amount of energy consumed by people has accelerated and increased substantially. As a result, due to greenhouse gases such as CO 2 The problems caused by global warming emerged. [0003] Considering the above facts, in order to suppress the generation of greenhouse gases as much as possible, the commercialization of the following power generation equipment is currently expected, which recovers as much as possible the waste and unused high temperature heat energy of ...
