ABSTRACT:
A heat-exchanger for gases of greatly varying temperatures, especially for use in gas turbines, which essentially consists of a collective space, for example, of a pipe-shaped collective space for the cold gas and of a metal recuperator which is formed by a large number of preferably U-shaped pipes which are welded or brazed into the collective chamber, whereby the hotter gases flow through between the pipes of the recuperator to give off some of their heat to the compressor air flowing through these pipes; one or several protective sheet metal members are arranged within the area of the connecting places between the pipes of the recuperator and the collective chamber which protect the welded or brazed joints against the hot gases.
