<p>PROBLEM TO BE SOLVED: To provide a thermoelectric power generator in which the power generation output density per unit volume can be increased, the weight and size can be reduced, the temperature of a heating face of thermoelectric conversion means can be increased more greatly, the temperature of a cooling face of the thermoelectric conversion means can be reduced more greatly, the cooling face of the thermoelectric conversion means can be sufficiently cooled at even a position distant from cooling water, and the maintenance performance is excellent.SOLUTION: A thermoelectric power generator has a first cylindrical portion 2 as a flow passage for cooling medium, a second cylindrical portion 3 which is disposed at the outside of the first cylindrical portion 2 to be spaced from the first cylindrical portion 2 at a predetermined interval and serves as a flow passage for heating medium, a heat transfer member 4 for connecting the inside area of the first cylindrical portion 2 and the outside area of the second cylindrical portion 3, and thermoelectric conversion means 5 disposed in the heat transfer member 4 in the outside area of the first cylindrical portion 2 and the inside area of the second cylindrical portion 3.</p> |
