ABSTRACT:
In order to prevent damage to the tube elements or the communicating pipe due to water collecting in a gap formed between the tube elements and the communicating pipe by defective brazing in a laminated heat exchanger, in which the water thus collected will be frozen and melted repeatedly, a structure that ensures that no water is collected in such a gap is achieved by making either one or both of the indented portions of the two formed plates, which constitute the indented portion of each tube element, not in contact with the communicating pipe.
