ABSTRACT OF THE DISCLOSURE This invention relates to a method for manufacturing a heat exchanger and to the heat exchanger manufactured by the method, especially, a type of a heat exchanger which has a plurality of pipes and end plates as the components for heat exchanging therein. For manufacturing of the type being of the heat exchanger with pipes and end plates, it is necessary to compose them so as to form paths for fluids between which heat is exchanged and so as to seal completely the paths. This invention enables to manufacture successfully such type of the heat exchanger in comparison with the conventional methods which need welding or brazing of the pipes with end plates to seal the paths. A compact heat exchanger with complete sealings is obtained by the invention and it is free from troublesome and laboring works of welding or brazing.
