Patent ID: 8839614

Claim:
A thermoelectric generator for a vehicle mounted at an exhaust pipe through which exhaust gas flows and produces electricity using a temperature difference between the exhaust gas and coolant, the thermoelectric generator comprising: a cylindrical housing through which the exhaust pipe is penetratively mounted; thermoelectric modules mounted at an outer circumferential surface of the housing so as to form a plurality of columns along a longitudinal direction of the housing, which thermoelectric modules produce electricity according to the temperature difference; a plurality of coolant tubes through which the coolant flows, the plurality of coolant tubes mounted so as to closely attach the thermoelectric modules to the housing and closely attached for each of the columns of the thermoelectric modules; first coolant containers mounted at opposing ends of the coolant tubes, respectively, so that the coolant tubes positioned at one side in a longitudinal direction of the housing are opened, the first coolant containers in which the coolant flows in and out; and second coolant containers mounted at opposing ends of the coolant tubes, respectively, so that the coolant tubes positioned at the other side in the longitudinal direction of the housing are opened, the second coolant containers in which the coolant flows in and out.
