Claims

[Claims for Utility Model Registration] (1) A plurality of tube elements 6 and heat transfer fins 13 are alternately laminated to form a core part 7, and a single plate of clad material is attached to the end of this core part 7. A two-part type inlet or outlet collecting pipe 1 formed by forming joint parts 22a and 22b on the outer peripheral edge by pressing.
In the laminated evaporator in which the pipes 5 and 16 are brazed, the pipes 18 and 19 inserted into the pipe insertion portions 21 of the collecting pipes 15 and 16 and the joint portion 22a,
the pipe 1 so as to close the gap created between the
A laminated evaporator characterized in that a gap closing part 33 for closing the gap 25 is integrally provided in the pipe insertion part 8, 19 and/or the pipe insertion part 21. (2) The gap closing portion 33 includes fitting recesses 31 and 4 formed on the inner surface of the pipe fitting insertion portion 21 so as to intersect with the joining portions 22a and b in the radial direction.
1, and fitting convex portions 32, 42 formed at the ends of the pipes 18, 19, according to claim 1. (3) The gap closing portion 33 is connected to the pipe 18,
19. The stacked evaporator according to claim 1, which is constructed by fitting a bead portion 36 formed in the axial direction of the outer wall into the gap 25.
