Abstract
In an exhaust heat recovery system for an internal combustion engine, a heat pipe includes an evaporation portion in which a working fluid is heated and evaporated by heat exchange with exhaust heat from the internal combustion engine, a plurality of condensing portions in which the working fluid from the evaporation portion is cooled and condensed by heat exchange with respective subjects to be heated, and connection piping through which the condensing portions are connected to the evaporation portion in parallel with respect to the evaporation portion so as to form a closed circuit. Furthermore, a switching portion is located to switch a flow of the working fluid from the evaporation portion to any one between the condensing portions.
