Thermoelectric generator

A thermoelectric generator for recovering electric power from waste heat generated from an engine, the thermoelectric generator comprising:

• a high temperature heat source part provided on a first passage through which a first fluid for cooling the engine flows for receiving heat from the first fluid;
• a low temperature heat source part provided on a second passage that is separate from the first passage for receiving heat from a second fluid flowing through the second passage, the second fluid having a temperature lower than that of the first fluid;
• and
• a thermoelectric element located between the high temperature heat source part and the low temperature heat source part for producing electric power by a temperature difference between the high temperature heat source part and the low temperature heat source part, wherein
• the first passage is included in a first circuit that connects the engine and a first radiator for cooling the first fluid in a loop through a main passage,
• the first passage is disposed in parallel to the first radiator in the first circuit, and
• the second passage is included in a second circuit that is separate from the first circuit and has a second radiator for cooling the second fluid.
