PROBLEM TO BE SOLVED: To provide a vehicle stacked thermoelectric generator capable of maximizing power generation efficiency by improving a heat exchange structure constituted by a heating unit and a cooling unit.SOLUTION: A thermoelectric generator includes: a thermoelectric generation unit mounted between an exhaust gas inlet pipe and an exhaust gas outlet pipe, the thermoelectric generation unit being an assembly of a plurality of unit modules including a first thermoelectric element and a second thermoelectric element. A cooling water inlet is formed in an upper portion of the outermost unit module in a direction of the exhaust gas outlet pipe, and a cooling water inlet-side sealing plate is provided in a lower portion thereof. A cooling water outlet is formed in a lower portion of the outermost unit module in a direction of the exhaust gas inlet pipe, and a cooling water outlet-side sealing plate is provided in an upper portion thereof. A pair of exhaust gas circulation passages in which exhaust gas flowing into the exhaust gas inlet pipe circulates are formed at the right and left of the unit modules, respectively, and a pair of cooling water circulation passages in which cooling water flowing into the cooling water inlet circulates are formed on upper and lower sides of the unit modules, respectively. |
