Abstract

PROBLEM TO BE SOLVED: To obtain a laminate type heat exchanger comprising a pan type plates having a central partitioning protrusion in which shift of inner fins is eliminated during assembling work and the partitioning protrusions of adjacent pan type plates can be jointed rigidly with no gap. SOLUTION: Adjacent fringe parts of inner fins 15a, 15b on the opposite sides of the partitioning protrusion 1 of a pan type plate 4 are coupled through a coupling part 15c straddling the partitioning protrusion 1 to form an integrated inner fin 15. Abutting parts 17, 18 for positioning inner fin are provided on the opposite sides at the end part of the partitioning protrusion 1 and on the inside at the opposite edge parts of the pan type plate 4. Step parts 19 having a depth equal to or less than one half of the thickness of the coupling part 15c of the inner fin 15 are formed at the opposite ends on the upper surface of the partitioning protrusion 1 such that the coupling part 15c of the inner fin 15 enters between both step parts 19.

However, when assembling the heat exchanger by stacking a large number of the plate-shaped plates (41), the inner fins (45) are moved from a predetermined position of the plate-shaped plate (41) to one end. In some cases, if the brazing is performed in this state, a large increase in the refrigerant passage resistance occurs in the heat exchanger.

When a large number of plate-shaped plates (41) each having a partitioning ridge (42) in the center are stacked, the partitioning ridges (42) of adjacent plate-shaped plates (41) are brought into contact with each other. In this case, the brazing filler metal of both partitioning ridges (42) is in direct contact with each other, and there is a tendency that the brazing filler metal that has been melted does not evenly distribute on the joint surface. Phenomena are likely to occur, and due to this, the ridges for both partitions (42)
So-called refrigerant shortcuts occur between
There have been problems such as the occurrence of poor pressure resistance. Further, when a large number of dish-shaped plates (41) are fixed by a jig and brazed, a gap may be formed between the two partitioning ridges (42), resulting in poor brazing.

In addition, in the present invention, since the partitioning ridges of the adjacent plate-shaped plates are not directly joined to each other but are joined to the opposing surfaces of the coupling portion of the inner fin, respectively. The brazing material in the partitioning ridges of the dish-shaped plate is equally divided and melted by the coupling portion of the inner fin, so that the occurrence of the brazing phenomenon is greatly suppressed. Furthermore, as described above, since the partitioning ridges of the adjacent plate-shaped plates are connected to each other via the coupling portion of the inner fin, no gap is formed between the partitioning ridges. Therefore, unlike the related art, there is no occurrence of a so-called short-cut of the refrigerant or a failure in pressure resistance between the two ridges for partitioning due to the brazing phenomenon.
