Abstract
813,589. Making heat exchangers; brazing. IMPERIAL CHEMICAL INDUSTRIES Ltd. Oct. 9, 1957 [Oct. 12, 1956], No. 31144/56. Classes 83 (2) and 83 (4). A method of making a heat-exchange device comprises bending to a substantially sinuous form a strip of metal, said strip incorporating a longitudinal laminated zone formed by an insert of weld-preventing material extending from end to end of the strip, placing tubular spacer members between adjacent sides of the strip in communication with holes formed in the laminated zone thereof, heating the assembly to effect brazing of the spacer members to the strip, and inflating the laminated zone in the strip material to form a passage extending from end to end of the strip, and communicating with the tubular spacer members. A rolled strip 1 of aluminium alloy, coated on both sides with a brazing alloy comprising aluminium with about 2 to 12 per cent silicon and with an insert of weld-preventing powder extending from end to end, is bent to sinuous form. Holes 5 are formed in each straight section of the bent strip and flanged tubular spacer members 7 and corrugated members 9 are then fitted between the said sections. The assembly is then brazed in a heated flux bath. The ends of the strips in the region of the stopweld are sealed and the strip is inflated so as to provide a passage extending from one end of the strip to the other and communicating with the spacer members 7. The strip 1 may be formed by rolling together two strips with stop-weld between them or by rolling a casting with an elongated member of stop-weld which is crushed to a powder during rolling. The holes 5 may be pre-formed prior to bending or may be punched through the bent strip in one operation. The tubular spacer members may be coated with brazing material. The tubular spacer members may be short, in the form of washers formed from a strip pre-coated on both sides with brazing material, or the washers may consist entirely of brazing material.
