Definitions

  • the present invention relates to a system for coupling and clamping a tank to an end manifold of a heat exchanger, such as, for instance, a radiator for motor-vehicles.
  • a purpose of the present invention is therefore to provide an improved system for coupling and clamping a tank to the manifold of a heat exchanger.
  • the system according to the invention enables extremely rapid and repeatable unclamping and uncoupling of the tank from the manifold, as well as their subsequent recoupling and reclamping.
  • the reference number 1 designates a tank designed to be fitted to an end manifold 2 of a heat exchanger (not illustrated), such as for instance a radiator.
  • the tank 1 is made, for example, of glass-fibre-reinforced polyamide.
  • the manifold 2 is instead made, for example, of metal material. It has, in a way of itself known, a main wall 2a (see Figure 1), in which there is made a plurality of openings 2b, to which the ends of the corresponding pipes of the heat exchanger are fixed, for example by means of brazing or mechanical expansion.
  • the wall 2a of the manifold 2 has a basically rectangular shape and is surrounded by a perimetral border or rim 2c, which is integral therewith.
  • each of the main sides of the manifold 2 from the rim 2c there extends a respective plurality of formations 4 set aligned to and at a distance from one another, basically shaped like hooks facing outwards.
  • the hook formations 4 of the manifold 2 have the concavity facing downwards.
  • the tank 1 has a basically rectangular border or rim and, along each of its main sides, in a position corresponding to the rim thereof that is to be coupled to the manifold, has a plurality of projecting formations 3 set aligned to and at a distance from one another.
  • the above projecting formations 3 have on top a respective longitudinal furrow 3a.
  • Said furrows 3a are basically aligned to one another.
  • the tank 1 In a position corresponding to each smaller side, adjacent to the rim facing the manifold 2, the tank 1 has a further projecting formation 5 provided on top with a respective furrow 5a.
  • the arrangement of the formations 3 and 5 of the tank 1 and of the formations 4 and 6 of the manifold 2 is such that the former can be interspersed with the latter when the tank 1 is fitted to the manifold 2 (see Figure 2) with interposition of an elastically compressible sealing gasket 7.
  • FIG. 1 illustrates the tank 1 fitted to the manifold 2 on the gasket 7.
  • each clamping member 9 is basically L-shaped, with a shorter branch 9a, designed to extend in a passage accordingly defined between the formation 5 of one side of the tank 1 and the corresponding formations 6 of the manifold 2.
  • each formation 6 is conveniently folded downwards over the branch 9a of the clamping member 9, as illustrated in Figure 3, so as to block it in turn and prevent it from sliding out.
  • the system described enables extremely fast and convenient unclamping and uncoupling of the tank 1 from the manifold 2. For this purpose, it is, in effect, simply necessary to raise the end tabs 6 of the manifold 2, and then, after compression of the tank-manifold assembly, slide out the clamping member or members 9.
  • the formations 4 and 6 of the manifold could have a C-shaped or L-shaped profile and be folded towards the inside of the manifold instead of towards the outside.
