Round thermoelectric generator of automobile exhaust semiconductor

Abstract

The invention discloses a round thermoelectric generator of an automobile exhaust semiconductor. The thermoelectric generator consists of a thermoelectric module (3), a heat collector with bumped outer edges (4), a radiator (8), graphite paper (2) and a voltage stabilizing transformer (5). The inner hole sleeve of the heat collector with bumped outer edges (4) is locked on the outer wall of a round exhaust discharge pipeline (1); the two sides of the bumped part of the heat collector with bumped outer edges (4) are respectively fixed with a thermoelectric module (3); the cold surface and the hot surface of the thermoelectric module (3) are both labeled with graphite paper (2); the hot surface of the thermoelectric module (3) is glued with the bumped part of the heat collector (4) through the graphite paper (2), and the cold surface of the thermoelectric module (3) is glued with the radiator (8) through the graphite paper (2); the thermoelectric module (3) is connected with an automobile power supply system through the voltage stabilizing transformer. The temperature resistant of the power semiconductor generating device can reach 400 DEG C, besides, the round thermoelectric generator has the characteristics of stable voltage, high power, maintenance free, long service life, simple structure and convenient use and is suitable for the utilization of the automobile exhaust residual-heat.

Description

technical field [0001] The invention relates to a circular automobile exhaust semiconductor thermoelectric generator, which belongs to the technical field of semiconductor thermoelectric power generation. Background technique [0002] With the rapid development of the global economy, the output of automobiles continues to increase, and the pollution of automobile exhaust to the environment is becoming more and more serious. According to research, the power output of automobile engines accounts for 25%-42% of the total heat of fuel combustion, and the rest is discharged from cooling water and exhaust in the form of waste heat. The waste heat of engine exhaust gas has the characteristics of high temperature, and the heat contained in it accounts for the main part of the wasted energy. If the heat energy in the tail gas can be converted into other usable energy forms, such as electric energy, the efficiency of energy use can be effectively improved, and the tail gas pollutio...

Problems solved by technology

Due to various reasons such as the thermoelectric device itself and the structure of the device, the existing automobile exhaust power generation device cannot adapt to the high temperature working conditions of the automobile exhaust, and the frequent thermal expansion and contraction greatly lead to the instability of the device, which seriously restricts the performance of the automobile.
