International ClassB23P 015/00Foreign Application Priority Data1991-05-14 FRAbstractIn a heat exchanger of the kind suitable for use as a condenser in a motor vehicle air conditioning installation, a manifold has a cylindrical tubular wall and is divided into compartments by means of baffles, which are introduced through an open end of the tubular wall. Heat exchange tubes extend into the compartments of the manifold through apertures formed in the tubular wall. After the baffles have been slid into place within the tubular wall, deformations are formed in the tubular wall so as to retain the baffles in place, prior to insertion of the heat exchange tubes and brazing to secure the components of the assembly sealingly together. | |
