“…The higher the temperature gradient, the higher the power output produced by TEG. Kiflemariam and Lin [12] researched the self-cooling mechanism for an array of TEG modules. The power generated by TEGs is able to run a fan which cools down the device temperature up to 20%.…”

Thermoelectric Generator (TEG) provides unique advantages as compared to other heat engines as it is capable to convert heat to electricity directly without having any moving parts. Furthermore, TEG is compact, simple and noiseless and requires very minimal maintenance. This paper presents an experimental and analytical study of a model consisting of a TEG located between a copper water cooling jacket and an aluminium block which acts as a heat spreader. The copper water cooling jacket was used in this study as water has higher thermal capacity than air. Besides, copper is one of highest thermal conductivity materials. TEG characterisation in term of electrical was investigated in this study. Based on the result, it shows a linear proportion relationship between open-circuit voltage and temperature difference across TEG. The result also clearly shows the power output of TEG increases as the temperature gradient across TEG increases. In addition, the impact of water flowrate on TEG power output was also studied. Based on the finding, there was an optimum water flowrate of 80 ml/s. Further increasing the water flowrate is not favourable as it will not increase power output and may lead to higher pumping power for water circulation. At this optimum water flowrate, the maximum power output obtained is equal to 530 mW when TEG hot-side temperature (Th) is 180 ℃.

“…In their study, the effects of different parameters applied in geometry on cooling performance were examined. According to the results, when the highest heat input is applied, a decrease of 20-40% was observed in the device temperature [17]. As a result of the studies conducted by Wang and Bar-Cohen, it has been observed that thermoelectric self cooling application applied locally on germanium chips can reduce the temperature rise in micro heat sources.…”

“…Cooling utilizing force air cooling systems has attracted attention among researchers given the drawbacks of the natural air cooling system, that is, a relatively large volume and mass weight [18]. The cooling system on the cold surface of the TEG has been considered by Robel K. et al [19], who discussed the experiment of a cooling system based on a selfcooling system. This paper investigated the effect of the self-cooling system on the value of heat dissipated efficiency when compared with a heatsink (natural air cooling system).…”

Two third of the total energy in the internal combustion engine (ICE) system is lost and turns as waste heat through the exhaust system and coolant circulations. Therefore, it is necessary to have a technology that is able to convert waste heat from ICE into electrical energy using thermal electric generator (TEG). To have the best thermoelectric generator (TEG) performance in terms of higher electricity generation, the temperature on the hot surface should be higher, and the temperature on the cold surface should be as low as feasible. The goal of the study was to study how differences in TEG cooling systems affected the overall performance. Water block and heatsink-fan are two different types of cooling systems that have been used in this experiment. The water flow rate in water block cooling systems varies between 200, 300, 400, 500, and 600 l/h. The TEG module was heated with gas-fired lighters. Arduino-based data loggers were used to record hot and cold temperatures on the TEG surface. A USB multimeter is used to measure TEG performance as electrical voltage. The results showed that 300 l/h was the best water flow rate for TEG cooling. When using a water block cooling system instead of a heat sink, the electrical voltage generated by the TEG module is 12 percent higher. This study found that a cooling system with water blocks is superior to heatsink-fan.
