- Abstract
The efficient recovery of the waste heat from the industrial sector can represent an essential step in global energy saving, with the proper usage of other on-grid power resources available for specific high-energy consumers. A simple, low--cost energy conversion system was tested here to recover a part of the waste heat dissipated by a gasoline engine's exhaust pipe under the car's stationary testing mode at temperatures around 80-100 °C. The main components of this system were a copper--made thermal collector, a commercial thermoelectric energy generator (TEG) module TEC1 -- 12706 and a pin-fin heat sink under natural air convection cooling. Under the open-circuit test, heat transfer rates between 4.54 W and 5.56 W were evacuated by the heat sink. A DC electronic load RL was connected at the TEG outputs, and voltage values between 0.566 V and 1.242 V were recorded for output power values between 0.03 W and 0.16 W when RL was modified from 1 Ω to 10 Ω .
