In a method for crimping a tube end plate of a heat exchanger on a header box, there is provided a peripheral upright edge for enclosing an extra thickness defined by the header box. Portion of the upright edge of the tube end plate which has to extend, when assembled, at least in part above a flange of the header box is stiffened. The stiffened portion of the upright edge of the tube end plate is folded at least partly back onto the flange of the header box.

Method for crimping a tube end plate of a heat exchanger on a header box

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.
