Waste heat recycling system for vehicle internal combustion engine, has thermo-switch limiting amount of heat and isolating part formed between evaporator and condenser and having wall section to avoid heat transfer from external fluid

摘要

The system has a heat conductor (110) with an evaporator arranged at an exhaust gas conductor. A condenser is arranged in a cooling water passage for carrying cooling water. A thermo-switch limits the amount of heat based on rising quantity of heating of the evaporator. An isolating part formed between the evaporator and the condenser is provided with a wall section (160) to avoid heat transfer from an external fluid.
