Experimental Study: Design of Thermoelectric Generator (TEG) Fixture for Harvesting an Automobile Electricity

The automotive technology race to improve the efficiency of engine performance is increasing, one of which is the use of heat energy in car radiators. This is in addition to reducing the workload of the engine. It can also produce electrical energy. This experiment uses four pieces of TEC1-12706 thermoelectric generators (TEG) which are arranged in series with heat sink construction in the direction of the fluid flow mounted directly above the TEG fixture. TEG Fixture will be installed on Lombardini diesel engine upper hose radiator LDW1404. This experiment produces a maximum voltage of 2.05 volts, with the current strength of 68.4 mA (0.064 A) and the power generated is 140.22 mA (0.14 A) with a difference in heat sink temperature from the heat side of 17, 8°C.
