ABSTRACT:
A method for the manufacture of heat exchangers where tubes of rectangular section are assembled with dissipators for forming a plane core which is curved by applying a bending force on the small sides of the tubes, thereby making cores. These cores are assembled by engaging the ends of the tubes into tubular plates which are part of boxes.
