Claim:
1. A coupling system as a thermal interface between a waste-heat generator and a waste-heat receiver, said coupling system comprising; a first body having a first contact area; a second body having a second contact area, said first and second contact areas abutting one another for heat exchange; and a tongue and groove connection provided in two edge regions of the first and second contact areas and in a central region of the first and second contact areas which is substantially central and equidistant from the edge regions, the tongue and groove connection having a plurality of grooves extending vertically in a longitudinal direction and spaced horizontally from each other and a plurality of tongues formed as sliding blocks inserted in each of the grooves and spaced vertically from each other and connecting and tensioning the first and second contact areas, wherein the plurality of grooves of the tongue and groove connection includes three grooves, with two of the grooves arranged adjacent to two vertical edges of the first contact area correspondingly and a third of the grooves arranged horizontally between the two grooves and substantially centrally and equidistantly from the two grooves, wherein the sliding blocks are fixed in the first contact area, and a spring element is positioned on an element of the tongue and groove connection and provides in mounting condition a restoring force acting substantially in a direction of surface normal of the first and second contact areas so that due to the restoring force a contact pressure which forces the first and second contact areas to one another is increased, wherein the element of the tongue and groove connection on which the spring element is positioned is the sliding block of the tongue and groove connection, wherein each of the sliding blocks is T-shaped and has a base and a crossbar extending perpendicular to the base, and the spring elements are secured on the crossbar on both sides of each of the sliding blocks.
