Heat exchanger core plate structure and heat exchanger core

摘要

Problem to be solved: to provide a plate structure of a heat exchanger core which is light weight, easy to assemble, and heat exchanger formed therein.Solution: in the heat exchanger core in which a plurality of plate structures 7 are laminated in the thickness direction, the plate structure 7 is characterized in that a coiled bent portion 3 is formed by bending both ends of the plate 1 into a U-shaped cross section, and a bar material is disposed in the coiled bent portion 3.Diagram
