Thermoelectric generator of vehicle

A thermoelectric generator of a vehicle comprising;

• a high temperature member having:
• an exhaust pipe, through which a high temperature exhaust gas passes, wherein the exhaust pipe is heated by a heat exchange process with the exhaust gas;
• a ring-shaped first heat transfer plate equipped with a first flange installed on an external wall of the exhaust pipe and formed along a longitudinal direction of the exhaust pipe;
• a low temperature member having:
• a first coolant pipe enclosing an external wall of the exhaust pipe with a predetermined space therebetween, and inside of which a coolant runs;
• and
• a ring-shaped second heat transfer plate installed inside the first coolant pipe, and on which a second flange extends along a longitudinal direction of the first coolant pipe;
• and
• ring-shaped thermoelectric modules, which are formed by joining a P-shaped semiconductor and an N-shaped semiconductor, and one side of each of which is in contact with the first heat transfer plate and the other side of each of which is in contact with the second heat transfer plate so as to generate electricity using a thermoelectric phenomenon caused by a temperature gap between the two sides.
