Method for fixing components to a pipe for circulation of a fluid forming part of a heat exchanger, in particular a condenser of an air-conditioning system

The present invention relates to a method for fixing components to a pipe for circulation of a fluid forming part of a heat exchanger, in particular a condenser of an air-conditioning system. A method for fixing components to a pipe for circulation of a fluid forming part of a heat exchanger (), in particular a condenser of an air-conditioning system, the method envisaging at least one step of preliminary connection of at least one component () to the pipe (), followed by a brazing process in order to obtain final connection of the component () to the pipe (). According to the invention, in the course of said step of preliminary connection, the component () is mechanically fixed to the pipe () by means of at least one rivet () and, following upon said brazing process, fluid-tight sealing is obtained between the component (), the pipe () and the rivet () by means of melting of surface material ().
