Abstract: A thermoelectric generator system of an engine is provided and includes an insulating heat protective cover that is mounted within an engine. Additionally, a unit is disposed at an upper end of the heat protective cover to uniformly distribute heat energy to use the heat protective cover mounted at an upper end of an exhaust manifold of the engine to protect a wiring from exhaust heat. Accordingly, heat energy discarded from the exhaust manifold is absorbed to generate electricity using the waste heat discarded from the exhaust manifold without affecting the catalyst to improve the fuel efficiency of the internal combustion engine. Further, heat is transferred by conduction at a particular temperature or greater and heat is transferred by radiation and convection at a temperature less than the particular temperature to increase the efficiency.

Abstract: Disclosed is a housing for electronic/electrical that includes an inner panel and an outer panel, a strip of metal plate, and a strip of shape memory material. The inner panel and the outer panel are disposed parallel to each other at regular intervals to define an internal space. The strip of metal plate extends from an inner surface of the outer panel. The strip of shape memory material extends from an inner surface of the inner panel and is attached or detached to/from the metal plate on the outer panel while changing into an original straight shape or a bent shape according to a temperature variation. Here, when the temperature increase beyond a first transition temperature, the shape memory material straightens to form a heat transfer path. At a low temperature environment, the shape memory material bends and is separated from the metal plate to interrupt the heat transfer path.
