This invention relates to an integral high density thermo-generator including a heat insulating thermoelectric converter of integral net conversion elements and a separated independent sink among which, the converter is connected in an exhaust pipe, multi-stage axial arrayed thermoelectric converting elements are set in the channel, parallel semiconductor thermal couples comprise stereo electrodes to be connected and form a conversion network, the compensation lead of the network and the cold end connector in the cold source form a large scale thermoelectric circuit by connection. Cooling liquid circulation is applied for the independent sink, the system outputs DC current when operating to electricity-dependent devices by regulation of a DC regulator.
Description
technical field [0001] The invention relates to a thermoelectric generator, especially its heat source is the waste heat flow in the pipeline, and the thermoelectric conversion element is arranged in the pipeline, which has an axial-multi-stage-network-integrated-stacked structure; the cold source and heat The system is separated, and the large-scale thermoelectric circuit is formed by connecting the wire and the thermoelectric conversion element, and the energy conversion system that automatically converts waste heat energy directly into electrical energy. Background technique [0002] During the operation of the internal combustion engine, about 60% of the chemical energy of fuel combustion is not effectively utilized, and most of it is discharged into the ambient atmosphere through the exhaust pipe. The energy in the exhaust mainly includes waste heat energy and flow kinetic energy. The temperature is between 800-1200K. The airflow flows at a high speed and has one-dimens...
