Abstract: 1,234,270. Making heat exchangers. PEERLESS OF AMERICA Inc. 29 Nov., 1968, No. 56908/68. Heading B3A. [Also in Division F4] A method of making a tubular heat exchanger in the form of a sinuous tube 2 consisting of straight portions interconnected by bends, and wherein the straight portions extend through transverse fin plates 3, consists of forming in the fin plates, open-sided slots having a relatively narrow entry portion 7 leading Io a wider main portion 8, flattening the straight portions of the tube to permit insertion of the tube into the narrow portion of the slot as shown in Fig. 4, and thereafter by a simultaneous application of internal (e.g. hydraulic) pressure and external pressure (applied, e.g., by dies D 1  and D 2 , Fig. 2) expanding the tube into engagement with the main portion 8 of the slot. The various stages in the expansion of the tube are shown in Figs. 5 to 8, and the dies D 1  and D 2  act to maintain the tube wall at the zone 20, in contact with the fin during expansion and also at the same time to keep the portion 21 of the tube out of contact with the fin at the entry portion of the slot. This is said to prevent undesired deformation of the fin plates during the expansion. Flanges 16 are formed on the fins around the main portions 8 of the slots as shown particularly in Fig. 3. No bonding material such as solder is required between the fins and the tube. The tube may be made of aluminium and preferred dimensions for the slot and the tube are indicated in the Specification.
