Thermoelectric generator

Abstract

The invention relates to a thermoelectric generator which comprises a heat collector and a thermoelectric converter, wherein the heat collector comprises at least one heat absorption structure; the thermoelectric converter is arranged opposite to the heat absorption structure of the heat collector; the heat absorption structure of the heat collector absorbs heat and transfers the absorbed heat tothe thermoelectric converter; and the heat absorption structure comprises at least one carbon nano tube structure. The thermoelectric generator adopts the carbon nano tube structure as the heat absorption structure, and can enhance the energy absorption efficiency of the heat collector by utilizing the favorable endothermic character of the carbon nano tube structure, thereby obviously enhancing the thermoelectric conversion efficiency of the thermoelectric generator as compared with the prior art.

Description

technical field The invention relates to a thermoelectric power generation device. Background technique The energy problem is a major problem facing the development of contemporary human society, and people have developed many methods on how to obtain energy more effectively. All kinds of industrial waste heat and solar energy have the characteristics of small investment or no investment, so they have certain economic benefits and utilization value, but this kind of energy cannot be effectively utilized by other energy conversion methods. A better way to harness this type of energy. For a thermoelectric conversion device, the theoretical analysis formula of its energy conversion efficiency is T 1 is the high temperature end temperature, T 2 is the temperature at the low temperature end, and Z is a factor related to the material. It can be seen that for a thermoelectric conversion system, the heat conversion efficiency is not only related to the performance of the materia...
