ABSTRACT:
In a method for undetachably interconnecting discrete structural parts by means of a connecting or bonding material, the structural parts which are to be interconnected are arranged in an aligned manner in a hollow mold, and the interspaces between the hollow mold and the structural parts are filled with a sinterable metal powder. After the arrangement is heated to the sintering temperature of the metal powder, a sintered body results with at least partially embedded, rigidly interconnected structural parts, due to a diffusion bonding. Heat exchanger blocks may especially be produced according to such a method in a simple manner, without requiring that the separate structural parts must be pre-machined for an exact shape accuracy.
