<p>A tube radiator (10) having a plurality of connecting pieces (14), which are constructed in each case as a hollow part and each have no tube socket for the connection of a connecting tube (12), and which are welded at joints directly to one another or via tube pieces to form two collecting ducts which are connected to one another by connecting tubes (16), the end edge of the connecting tubes bearing in each case in the connection region against an annular bearing zone of the connecting piece, is constructed such that the end edge (26) of the connecting tube (12) and the annular bearing zone (26) of the connecting piece (14) are arranged in a plane (E) extending at right angles to the longitudinal central axis (24) of the end section of the connecting tube adjoining the connecting piece (14). Furthermore, a corresponding method for producing tube radiators is proposed. <IMAGE></p> |
