To provide an evaporator capable of improving the evaporation efficiency of a liquid, suppressing a pressure fluctuation caused by bumping generated when the liquid is evaporated, and controlling a stable evaporation behavior of the liquid.
The evaporator including a heat exchange core where channels of high temperature fluid and channels of low-temperature fluid are adjacent to each other, a low-temperature liquid fluid is allowed to flow downwardly from above the channels of the low temperature fluid, and a high temperature gaseous fluid is introduced, and is evaporated and vaporized by thermally exchanging both fluids through the partition, wherein a filler fills the channels of the low-temperature fluid, planar fins that resist the flow of the low-temperature fluid are further disposed on the low-temperature fluid side of the partition. It is desirable that the planar fins disposed on the partition are each of an angle of 3 to 60° downwardly relative to a perpendicular surface in the flowing-down direction of the low-temperature fluid.
