Claims

[Scope of utility model registration request]

Of the two sets of side edge portions facing each other of the rectangular plate main body, one set of side edge portions is provided with a first bent portion bent in the same direction, and the other set of side edge portions is bent in the same direction. Each portion has a second bent portion formed by bending in a direction opposite to the first bent portion.
The heat transfer plate body is provided with a plurality of heat transfer plate bodies each having a bent portion, and these heat transfer plate bodies are alternately inverted and stacked, and the tips of the bent portions facing each other are joined to each other. 1. A heat exchanger element characterized in that a plurality of mutually orthogonal fluid passages are alternately stacked.
