Thermoelectric generator for internal combustion engine

摘要

A thermoelectric generator for an internal combustion engine that prevents a thermoelectric generation element from being damaged. The thermoelectric generator includes a casing, which is arranged in an exhaust passage, and a sleeve. A cooling mechanism is arranged outside the sleeve. Thermoelectric generation elements are arranged between the sleeve and the cooling mechanism in a manner movable relative to both the sleeve and the,cooling mechanism. The thermoelectric generation elements convert heat energy from exhaust in the exhaust passage to electric energy.
