Abstract

Thermal energy is a source of energy that is widely used as an alternative energy source which with certain processes can be converted into electrical energy. One of the tools that can help the energy conversion process is a thermoelectric generator. The thermoelectric generator module is the main component in a system that applies thermoelectric phenomena to convert heat energy into electrical energy using the Peltier, Seebeeck and Joule effects on thermoelectrics that utilize the temperature difference between the two sides of the thermoelectric generator. In this research the generator output will be used to supply 12 Volt DC lamps. From the results of this study, it is known that the lowest output voltage produced by the thermoelectric module without load on the twine is 7.34 Volts with a ΔT of 30.99℃ while the highest output voltage that can be produced is 14.69 Volts with a ΔT of 66 ,69℃. And thermoelectric testing with a load that the minimum power that can be generated is 2.28 W with a voltage of 12.7 Volts and a current of 0.18 A. Meanwhile, the maximum power that can be generated is 5.07 W with a voltage of 13 Volts and a large current is 0.39 A. The efficiency value using the watertank cooling system also has an efficiency value of 0.21 which when compared to previous research has a better value
