PROBLEM TO BE SOLVED: To satisfy both enhancement of generation efficiency and reduction of power consumption of a refrigerant introduction pump, without requiring a large installation space in a thermoelectric generator 2.SOLUTION: In a first connection pipe 12, valves 21, 22 are provided between a refrigerant flow path 6 of odd row and a refrigerant flow path 6 of even row located on the downstream side of the refrigerant flow path 6 of odd row in the gas circulation direction. In a second connection pipe 13, valves 23, 24 are provided between a refrigerant flow path 6 of even row and a refrigerant flow path 6 of odd row located on the downstream side of the refrigerant flow path 6 of even row in the gas circulation direction. A control section 30 for controlling the open/close state of the valves 21, 22 on the first connection pipe 12 side and the valves 23, 24 on the second connection pipe 13 side based on the current velocity of refrigerant is provided. |
