Abstract

606,933. Making heat-exchangers. AKT.- GES. FUR TECHNISCHE STUDIEN. Jan. 22, 1946, No. 2099. Convention date, Jan. 30, 1945. [Classes 83 (ii) and 83 (iv)] Uniting by fusion.-In making tubular heatexchangers with tubes grouped together in nests and firmly connected at their ends to end walls, one end of a nest of tubes 4 is inserted loosely into the single opening of a frame 1 and the tubes are then welded at their ends to each other and to the framing into a block. The frame is provided with a groove 2 separating the welds from the main mass of the frame so as to facilitate welding. The tubes, after insertion into the frame may be widened quadrangularly or hexagonally at their ends by a hammer or pieces of wire 7 may be inserted between the parts and also welded to the ends of circular tubes and to the frame. A number of frames 5 and tube nest ends welded up into blocks are finally welded to the widened-out end of a common funnel-shaped member 8 which acts as a distributor or feeder, the narrow end being fixed in an end plate of the heatexchanger. The frame may be cut off from a square steel tube. Distance pieces may be provided between the tubes at the required distance from the frames.
