ABSTRACT:
A heat exchanger wherein a plurality of individual tubular parts are connected with each other is provided having a common pressure element for tube connections arranged in a plane. According to FIG. 1, a pressure platen 6 is present, which consists of a material harder than that of the external tubular part and is equipped with a number of orifices 7 corresponding to the number of tube connections. The pressure platen 6 surrounds the outer and inner tubular parts inserted in each other, and the diameter of the orifices 7 is smaller, at least in part, than the external diameter of the outer tubular part. According to the process for the manufacture of the heat exchanger, all of the tube connections are produced simultaneously by means of pressing on the pressure platen. Each of the tube connections is effected by reducing the cross section by means of plastic deformation of at least the outer, tubular part, whereby a press fit of the tubular part is obtained.
