Abstract: An object of the present invention is to provide a plate stacking type heat exchanger including plates having a small longitudinal dimension. In a plate stacking type heat exchanger 100 according to the present invention, an inlet port for low temperature fluid 59a and an outlet port for low temperature fluid 59b are provided on one end side in the longitudinal direction of a plate (left side in FIG. 1). A partition part formed of partition members 10a and 10b is formed in each low temperature fluid compartment 60. The low temperature fluid flows each of the low temperature fluid compartments 60 along a U-turn path that is not short in length.

Abstract: Problem to be Solved A plate laminate type heat exchanger having high heat exchange efficiency is provided. Solution In a plate laminate type heat exchanger 100, both ends of a protrusion 10 converge into an inlet port for high temperature fluid 58a and an outlet port for high temperature fluid 58b. A pair of core plates 53 and 54 is assembled in such a way that the side of the core plate 53 on which the protrusion 10 is not formed faces the side of the core plate 54 on which the protrusion 10 is not formed and the protrusions 10 and 10 formed on the respective core plates are paired but oriented in opposite directions. The pair of core plates 53 and 54 form a plurality of tubes surrounded by the walls of the protrusions 10 and 10, and the tubes form high temperature fluid compartments.

Abstract: In a plate laminate type heat exchanger a plurality of groove-like protrusions is formed on one side of each of flat core plates, and the protrusions extend substantially in parallel to one another from one end side in the longitudinal direction of the plate toward the other end side in the longitudinal direction of the plate, form a U-turn region in an area on the other end side in the longitudinal direction of the plate, and return to the one end side in the longitudinal direction of the plate. The plate is curved in such a way that ridges and valleys are formed on part of the plate, the area in which the protrusions are formed but the U-turn region is not formed, in the direction in which the plate is laminated and the ridges and valleys are repeated along the longitudinal direction. Both ends of each of the protrusions converge into an inlet port for high temperature fluid and an outlet port for high temperature fluid, respectively.
