<p>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, a plurality of groove-like protrusions 10 is formed on one side of each of flat core plates 53 and 54, and the protrusions 10 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 10 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 10 converge into an inlet port for high temperature fluid 58a and an outlet port for high temperature fluid 58b, respectively. A pair of core plates 53 and 54 (core 55) is assembled in such a way that the side of one of the two core plates 53 and 54 that is opposite the one side faces the side of the other one of the two core plates 53 and 54 that is opposite the one side and the protrusions 10 and 10 formed on the respective core plates are paired but oriented in opposite directions.</p> |
