“…Wang et al designed a metal foam-filled TEG device and studied the change of power generation performance of the TEG system by changing the pores density of the metal foam. At the same time, the paper explained that the inlet temperature at the hot end, the flow rate at the cold end, and the thermoelectric module connection method have important impacts on the power efficiency, heat transfer effect, and waste heat recovery rate [18]. From the results of the research on thermoelectric device design and performance analysis, it can be concluded that the arrangements of the hot and cold modules and the thermoelectric module of the TEG device have an important influence on the performance of the entire generator.…”

“…The metal foams are filled in the heat sink duct to improve the heat transfer coefficient. Wang et al (2016a) used the metal foams filling the heat sink duct to enhance the heat transfer on both sides of the TEG. So the metal foams can improve the heat transfer coefficient effectively on the hot-air side and the water-cooling side.…”

In order to obtain the power generation of the thermoelectric power generator (TEG) group, a similar structure of the disc sandwich structure and an experimental system are built to analyze the power generation performance and temperature characteristics. To improve heat transfer and move heat from the hot side to the cold side, heat pipes with high thermal conductivity are arranged on the adjacent cold and hot plates of the TEG. The similar sandwich structure has 17 cold plates and 17 hot plates for the TEG pieces, which are connected in series on the circuit. Working conditions are hot air flow and cold water flow; hot air temperature and cold water temperature are set to a fixed temperature. The power generation of a single TEG is tested for verifying linear changes in the power generation performance with temperature differences (Td). Experimental results are that the power generation is improved by the air flow and water flow increasing. The water flow has a smaller effect on the power generation than the air flow. In the cold side of TEG pieces, the temperature of the cold side showed a gradual upward trend, the temperature of the hot side showed a wave trough phenomenon, and the Td showed a wave trough phenomenon. The hot air flow and the cold water changing cannot weaken the temperature trend of the hot side and the cold side. The hot air flow can more significantly increase the Td than the cold water.

A thermoelectric generator (TEG) is a device that transforms thermal energy directly into electrical power by exploiting the Seebeck effect. In the current study, the dynamic performance characteristics of a TEG is experimentally studied under different operating conditions. The Influence of input heat rate and the influence of utilizing extended surfaces (fins) on both transient and steady-state performance of a TEG are experimentally investigated. The variation in the temperatures of the TEG hot-and cold-side in addition to the output voltage is taken as a denotation of the performance characteristics. Input heating rate of 15.0 W, 17.5 W, 20.0 W, 22.0W and 25.0 W are applied to the TEG hot-side. Free air convection (FC) is utilized for heat dissipation from the TEG module through the cold-side. From the experimentation, it can be concluded that increasing the input heating rate provides a higher temperature difference between the module sides leading to higher power output. Additionally, using fins to aid heat dissipations improved the TEG performance by lowering the temperature of the cold-side and increasing the temperature difference across the module. The experimental data collected are compared with the data obtainable by the TEG module manufacturer and an excellent concordat is acquired.
