Thermoelectric generator of vehicle

A thermoelectric generator apparatus of a vehicle comprising;

• a high temperature member having:
• an exhaust pipe, wherein high-temperature exhaust gas passes therethrough;
• a ring-shaped first heat transfer plate surrounding the exhaust pipe, wherein the exhaust pipe exchanges heat with the first heat transfer plate;
• and
• a plurality of first heat exchange pins radially extending outwards from the first heat transfer plate in a predetermined degree;
• a low temperature member having:
• an internal casing surrounding the exhaust pipe;
• an external casing surrounding the internal casing with a predetermined gap to form a coolant flow route therebetween,
• a ring-shaped second heat transfer plate contacting with an internal wall of the internal casing;
• and
• a plurality of second heat exchange pins radially extending inwards from the second heat transfer plate in a predetermined angle;
• and
• a plurality of thermoelectric modules, which is formed by joining a P-shaped semiconductor and an N-shaped semiconductor, and a side of each of which is in contact with the first heat exchange pins, and the other side of each of which is in contact with the second heat exchange pins so as to generate electricity using a thermoelectric phenomenon caused by a temperature gap between the first heat exchange pins and the second heat exchange pins.
