1,256,228. Heat exchangers. ASSOCIATED ENG. Ltd. 26 March, 1969 [3 April, 1968], No. 16043/68. Heading F4S. In a heat exchanger assembly, particularly a radiator for an I.C. engine, adjacent tubular passages 1 are spaced apart and interconnected at their upper and lower ends by tubular members 5 which define manifold ducts for the liquid to be cooled. The tubular members 5 have flanges 6 which are bonded, by adhesive or welding, to the wall of the passages 1 around apertures 4 formed therein. In modifications (Figs. 3, 4, not shown) the tubular passage wall surrounding each aperture is formed with a depression (11) in which the flange (6) of the adjacent tubular member is located. Alternatively the periphery of each aperture may be flared outwardly (Fig. 5, not shown) to provide a lip (13) which engages with and is surrounded by a corresponding shaped flange (6a) on the tubular member. Cooling fins 7 are bonded to the external wall surfaces of the tubular passages, the fins being provided with louvres 9 or other means such as dimples or ribs to increase turbulence in the fluid flow over the fins. Straps (10, Fig. 2) located adjacent the tubular members surround the heat exchanger assembly. |
