Although not shown in the figure, the plates 16 and 19 are made of a material with solder holes clad on both sides, and the plates 16 and 19 are alternately laminated to form a well-known material such as vacuum brazing material, VAW brazing material, etc. This is a laminated heat exchanger 13 having a structure in which a brazing layer 20 is formed and fixed at the interface between a sieve plate 16 and a plate 19 using the furnace brazing method.

Since the excess brazing material is maintained by forming the reservoir 22, the joint sealing property between the plates 16 and 19 is more perfect. A heat exchanger is obtained.

It is also possible to alternately stack the plates 19 and provide grooves on the outer periphery to provide a reservoir for the brazing material, but it is better to provide the grooves on the refrigerant collecting holes and refrigerant passage holes that are in contact with the refrigerant. Since the pressure on the refrigerant side is usually higher, it is more effective to completely seal the refrigerant collecting holes and the refrigerant passage holes.

By reducing the external dimensions of one of the plates, a pool of brazing material can be formed during brazing in the grooves that are created as refrigerant collecting holes and refrigerant passage holes when two types of plates are stacked, allowing complete brazing. It provides a good seal and there is no leakage of refrigerant. Moreover, a laminated heat exchanger with high joint strength can be obtained.
