Thermoelectric generator for vehicle

A thermoelectric generator for a vehicle utilizing heat of exhaust gas discharged from an engine of the vehicle, comprising:

• a heat exchange unit, through which a coolant to exchange heat with the exhaust gas circulates;
• a thermoelectric generation unit for converting thermal energy of the exhaust gas into electrical energy;
• a first flow passage for guiding the exhaust gas discharged from the engine to pass through the heat exchange unit;
• a second flow passage for guiding the exhaust gas discharged from the engine to pass through the thermoelectric generation unit;
• a third flow passage for guiding the exhaust gas discharged from the engine to bypass the heat exchange unit and the thermoelectric generation unit without passing through the heat exchange unit and the thermoelectric generation unit;
• a first valve for opening or closing the first flow passage;
• a second valve for selectively opening or closing one of the second flow passage and the third flow passage;
• and
• a driving unit for operating the first valve and the second valve by a single power source.
