PROBLEM TO BE SOLVED: To provide a constitution which is achieved in the power generation conversion of the heat of gas, and can sufficiently cool an EGR gas in cooling the EGR gas of an internal combustion engine.SOLUTION: This generating set for converting the heat of an exhaust gas flowing in an EGR flow passage of an internal combustion engine into power includes: an EGR gas cooling part having a heat receiving region for receiving the heat of the exhaust gas, and a heat dissipation region for dissipating the heat to a cooling refrigerant; a thermoelectric module which has a high-temperature side face and a low-temperature side face, makes a clearance between the side faces function as the thermoelectric module for power generation, and is arranged so that the high-temperature side face receives the heat from a portion between the heat receiving portion and the heat dissipation portion of the gas cooling part; and a thermoelectric module cooling part having a heat receiving region for receiving the heat from the low-temperature side face of the thermoelectric module, and a heat dissipation region for dissipating the heat to the cooling refrigerant. Even when the EGR is not executed, the flow passage that causes the exhaust gas to pass by the heat receiving portion of the EGR gas cooling part is formed and the power is generated by the thermoelectric module.SELECTED DRAWING: Figure 1 |
