  • the interconnector members are disposed in abutting relationship with an extension of one member nested within the next member and bonded together to form a manifold, part of one or both abutting edges of adjacent interconnector members being cut away to define a slot in said manifold in which an end of a passage member is received, the slot being shaped to fit the end of the passage member.
  • the end of the passage member is shaped so as to allow the flowof said heat exchange medium lengthwise of the manifold.
  • each extension only extends over part of the periphery of the interconnector member, for example where the interconnector members are of circular cross-section the extension may have a substantially semi-circular cross-section.

  • FIG. 7 is a sectional view of part of the second embodiment of radiator employing the elements shown in FIGS. 2 6.
  • the radiator construction has a plurality of tubular passage members 1 arranged spaced apart side-byside and each formed from a pair of strip elements 2 of aluminum foil having a thickness of up to approximately 0.012 inch, for example of about 0.005 inch.
  • Each element is formed for example by pressing the strip to define a central channel provided with flanges along its side edges (as described with reference to FIGS. 5 and 6 below).
  • Adjacent the opposite ends of each passage member, each side wall provided with an aperture 4 and the apertures in adjacent passage members at each end of the assembly are interconnected by tubular interconnector members Shaving flanges 6 which are bonded to the walls of the passage members 1 around the apertures.
  • Each tubular member is also provided with an extension 7 of semi-circular cross-section which projects through the apertures 4 in the walls of a passage member and nests within the adjacentend of the next tubular member 5.
  • the tubular members may be made from a metal, e.g., as pressings or castings or by extrusion of a superplastic alloy.
  • the series of nested tu bular members which are disposed in line with each other thus form a manifold duct by means of which liquid may be fed to or removed from the passage members.
  • a similar manifold may be provided at each end of the assembly of passage members which form the radiator core.
  • Hose connections (not shown) may be provided for supplying liquid to and removing liquid from the manifolds and the ends of the manifolds may be sealed by means of cover members or plugs.
  • the heat exchange surfaces 8 may be of any desired form and as illusuated herein may comprise corrugated strips of metal foil defining fins extending generally transversely to the passage members and formed as described in US. Pat. No. 3,512,707 issued July 28, 1970.
  • the fins are preferably provided with louvres in order to increase the turbulence of the fluid flowing over the fins and hence the heat exchange efficiency.
  • Other types of tin structure besides that shown may of course be employed.

  • the member 10 is of generally circular cross-section, and is provided at one end (FIG. 3) with an extension 11 of semi-circular cross-section, which is adapted to nest within the end of an adjacent, similar member.
  • a semi-circular end surface 12 at said one end is adapted to abut an end surface 13 at the other end of the adjacent member.
  • the surface 13 is continued for more than a semi-circle.
  • a pair of surfaces 14 are formed on said one end, which are parallel to the plane of surface 12 and set back from it by an amount equal to the total thickness of edge flanges of the tubular passage member 9.
  • Each surface 14 has the form of half a segment of a circle, and the surfaces are disposed on either side of the plane of symmetry of the member.
  • a further surface 15 is also formed on said i one end of the member 10, this further surface also being parallel to surface 12 and being set back from surface 14 by an amount to allow for the main portion of the tubular passage member 9.
  • the inner periphery of surface 15 extends over a complete semi-circle, and may have a slightly greater extent by slightly cutting away the inner periphery of the ends of semi-circular extension 11, as indicated at 16.

It is set back from surface 13 by the same amount that surface 15 is set back from surface 14. Moreover the thickness of the member 10 in the region of surface 17 is greater than at the diametrically opposite point, for reasons which will become apparent.
