“…It has an open circuit voltage of 856.3 V and an output power of 150.58 W. However, the water-cooling method requires additional energy consumption based on the installation load of complex pipes. Murčinková et al [10] tested the output performance of the stove-power TEG under forced air cooling with a temperature difference of 94 • C and an output power of 1.5 W. Chen et al [11] also simulated forced convection cooling of natural wind speed by Taguchi optimization and operated it at low mass waste heat temperature to further improve TEG performance. Nevertheless, the installation of fans in practical applications often encounters challenges such as noise, structural design, and maintenance issues, leading to limitations in their applicability.…”

Cement-based material encapsulation is a method of encapsulating electronic devices in highly thermally conductive cement-based materials to improve the heat dissipation performance of electronic components. In the field of construction, a thermoelectric generator (TEG) encapsulated with cement-based materials used in the building envelope has significant potential for waste heat energy recovery. The purpose of this study was to investigate the effect of cement-based materials integrated with aluminum heatsinks on the heat dissipation of the TEG composite structure. In this work, three types of thermoelectric work units encapsulated with cement paste were proposed. Moreover, we explored the effect of encapsulated structure, heat dissipation area, the height of thermoelectric single leg, and heat input temperature on maintaining the temperature difference between the two sides of the thermoelectric single leg with COMSOL Multiphysics. The numerical simulation results showed that under the conditions of a heat source temperature of 313.15 K and ambient temperature of 298.15 K, the temperature difference between the two sides of the internal thermoelectric single leg of Type-III can maintain a stable temperature difference of 7.77 K, which is 32.14% higher than that of Type-I and Type-II (5.88 K), and increased by 26.82% in the actual experiment. This work provides a reference for the selection and application of TEG composite structures of cement-based materials combined with aluminum heatsinks.

“…In the world, almost all production processes that require internal combustion will produce wasted heat energy reaching 60% of the total energy used [1] [2], waste heat resulting from the internal combustion of the production process becomes more useful energy [3]. One alternative to the use of wasted heat is to use a thermoelectric generator (TEG) module based on the "Seebeck" effect, where the "Seebeck" effect is phenomena technology to directly transform heat energy into electrical energy [4] [5]. The conversion technology has the advantages of no moving parts, maintenance free and good durability [6] [7].…”

Thermoelectric Generators (TEG) are a type of energy conversion device that uses the Seebeck effect to directly transform heat energy into electrical energy. The source of heat that will be transformed using this technology is one of many elements that determine TEG performance. Through laboratory-scale experimental tests, this research will examine how the performance of TEG in producing electricity and the temperature distribution profile is affected by changing the heating rate. The hot surface of the TEG module is heated by the heating plate, which is thought of as a source of wasted heat produced by the internal combustion engine. There are three heating rates available: low heating rate (0.35 °C/min), middle heating rate (0.93 °C/min), and high heating rate (1.55 °C/min). To collect temperature data in this research using the Arduino microcontroller temperature data logger, temperature measurements were taken on the TEG module’s hot surface (Th), cold surface (Tc), and ambient temperature (Ta). Arduino data logger is used to measure the electrical output performance in the form of net power output (P) generated by the TEG. The outcomes demonstrate that the pace of heating on the hot surface of the TEG module will impact to the surface temperature differential and the efficiency of the TEG module in producing electricity. The efficiency of TEG in producing electricity in the form of an average net power output increases with an increased heating rate.
