Claims

[Scope of utility model registration request]

A tube element 5, which has a refrigerant evaporation chamber 4 formed inside by joining a pair of dish-shaped tube sheets facing each other, and a large number of corrugated fins 6, which are formed by bending a flat plate into a wave shape, are alternately and closely attached. A plurality of protrusions are provided on the inner surface that protrude into the refrigerant evaporation chamber and have flat tips, and the pair of tube sheets are brazed to each other at the peripheral edge of the protrusions and a part or the entire surface of the flat surface of the protrusions. In the laminated type evaporator, the protrusion formed in approximately 2/3 of the upstream side of the tube sheet 21 in the air flow direction is an elongated protrusion 23 that is inclined with respect to the air flow direction, and In this laminated evaporator, the protrusions in approximately 1/3 of the sides are circular protrusions 24.
