<p>PURPOSE: A thermoelectric generator for a vehicle is provided to charge a battery by generating electricity by being installed in a vehicle engine, thereby improving fuel efficiency. CONSTITUTION: A thermoelectric generator for a vehicle comprises a high-temperature unit(110), a low-temperature unit(120), and thermoelectric modules(140). The exhaust gas of high temperature flows inside the high-temperature unit having a polygonal cross section. The low-temperature unit includes a first cooling water pipe holder(132), a heat transmission plate(134), and a second cooling water pipe holder. The first cooling water pipe holder is formed in one side, thereby supporting a cooling water pipe(135). The heat transmission plate is extended from the first cooling water pipe holder and arranged in the outer sides of the-high temperature unit. The second cooling water pipe holder is formed in the other side of the heat transmission plate, thereby supporting the cooling water pipe. The thermoelectric modules are formed by welding a P-type semiconductor and an N-type semiconductor and interposed between the high-temperature unit and the low-temperature unit. The thermoelectric modules generate electricity by a thermoelectric phenomenon caused by a temperature difference of the high-temperature unit and the low-temperature unit.</p> |
