Compact-type thermoelectric power generation device

Abstract

The invention provides a compact-type thermoelectric power generation device and belongs to the engineering thermophysics and new energy cross technical field. The device comprises a compact-type thermoelectric power generation module, a thermal fluid heater, a cold fluid cooler, a thermal fluid circulating pump, a cold fluid circulating pump and cold/ thermal fluid pipelines and the like. The compact-type thermoelectric power generation module is formed by a front end cover guide plate, an A-B-C-D series guide plate combination and a back end cover guide plate, which are stacked up in sequence. The compact-type thermoelectric power generation module has cold fluid and thermal fluid circulation channels, wherein a cold fluid inlet channel and a cold fluid outlet channel form a cold fluid circulation system with the cold fluid pipeline, the cold fluid circulating pump and the cold fluid cooler, and a thermal fluid inlet channel and a thermal fluid outlet channel form a thermal fluid circulation system with the thermal fluid pipeline, the thermal fluid circulating pump and the thermal fluid heater. A plurality of thermoelectric devices are arranged between cold fluid and thermal fluid guide plates in the compact-type thermoelectric power generation module, and the thermoelectric devices convert the heat into electric energy and output the electric energy.

Description

technical field [0001] The invention relates to the interdisciplinary technical fields of engineering thermophysics and new energy, in particular to a compact thermoelectric power generation device. Background technique [0002] Under the action of temperature difference, thermoelectric devices can convert thermal energy into electrical energy (Sai ​​shell effect), and semiconductor thermoelectric devices have high thermoelectric conversion efficiency. In a traditional thermoelectric power generation system, a thermoelectric device is directly in contact with a heat source, or is installed on a high-temperature wall of a heat source (such as a pipe wall). The traditional thermoelectric power generation device has the following disadvantages: [0003] First of all, in traditional thermoelectric power generation devices, thermoelectric devices are installed near heat sources, such as waste heat flue gas pipes, high-temperature walls, etc. Due to the limitation of installation...

Problems solved by technology

[0003] First of all, in traditional thermoelectric power generation devices, thermoelectric devices are installed near heat sources, such as waste heat flue gas pipes, high-temperature walls, etc. Due to the limitation of installation locations, the number of thermoelectric devices installed is limited, which limits the power increase of thermoelectric generators;

[0004] Secondly, the traditional thermoelectric power generation device only enhances the heat exchange of the cold end of the thermoelectric device. Due to the limitation of t
