Abstract
In order to solve the problem of low utilization rate of industrial low-grade thermal energy and actively implement the national policy of energy conservation and emission reduction, a low-temperature differential Thermoelectric generator device is designed and implemented based on the thermoelectric effect. According to the basic heat flow method of thermodynamics, the vertical installation sequence of the instrument is determined, and the simulated heat source is carried out in the laboratory. DJR-G type silicon rubber heater is used as the heating device, the fin radiator is used as the radiator and combined with the insulation layer to build the Thermoelectric generator test platform. STM32 microcontroller is the main control core of the instrument; tec1-12708t200 thermoelectric module is the power generation carrier; the main output characteristic parameters of the instrument are displayed on LCD in real time, and the change curve of the output parameters is monitored on the upper computer in real time. The experimental data show that when the load resistance is 2.5 Ω, it matches the equivalent resistance, and its output power reaches the maximum value; when the cold end of the Thermoelectric generator device is effectively cooled, its output power will increase by 0.1W. The conclusion shows that the instrument can effectively realize the Thermoelectric generator function and improve the utilization rate of low-grade thermal energy.
