Abstract
A heat exchanger includes an evaporation side heat pipe in which a working fluid flowing therein is heat exchanged with a high-temperature fluid to be evaporated, a condensation side heat pipe in which the working fluid flowing therein is heat exchanged with a low-temperature fluid to be condensed, and an inner fin located at least in the evaporation side heat pipe to increase a heat transmission area of the evaporation side heat pipe with the working fluid. The evaporation side heat pipe and the condensation side heat pipe are connected to form a closed cycle, and the evaporation side heat pipe is arranged such that the working fluid flows in the evaporation side heat pipe in a direction different from a horizontal direction. Furthermore, the inner fin has a bottom end that is positioned above a top surface of the working fluid at least in a liquid state.
