Definitions

  • the present invention relates to a radiator element according to the preamble of claim 1.
  • a radiator element is known from WO2007/138627 A1 .
  • the present invention applies to die-cast radiator elements in which after extracting the element from the mould, the element has an open end needed for the extraction of a male or sword required to make the internal cavity of the element destined to house the radiant fluid.
  • a cap is placed next to the open end and is welded to the head by means of a welding robot, typically by brazing or autogenous welding, i.e. without the addition of material.
  • the purpose of the present invention is to make a closing cap which overcomes the drawbacks mentioned with reference to the prior art.
  • reference numeral 4 globally denotes a radiator element provided with a cavity 8 and suitable to be crossed by a heat exchange fluid, typically water.
  • the radiator element extends in a main axial direction X-X.
  • radiator elements joined in a battery, constitute, in the known manner, a radiator.
  • the radiator element 8 may be obtained by die casting, in which the cavity 8 is usually obtained through the use of a male or sword, of an elongated shape, which following the injection of metal, is extracted. The end from which the sword is extracted is thus an open end 12.
  • Said open end 12 has a cylindrical configuration, preferably axialsymmetric with respect to the main direction X.
  • the radiator element 4 comprises a closing cap 16 facing and sealed in a watertight manner to said open end 12.
  • the closing cap 16 is coupled according to a shaped coupling to the open end 12, as further described below.
  • the closing cap 16 has an axially symmetrical shape, preferably relative to an axis coinciding with the main axial direction X of the open end 12 of the radiator element 4; for example said closing cap 16 has a circular course and is counter-shaped relative to the open end 12 so as to occlude the same.
  • the closing cap 16 is made of galvanized or aluminized or stainless steel.
  • the closing cap 16 comprises a closure portion 20 at least partially inserted in said open end 12, and a coupling collar 24 at least partially folded at a front edge 28 of said open end 12, so as to realise the mechanical coupling between the closing cap 16 and said open end 12.
  • watertight sealing means 32 are positioned between the open end 12 and the closing cap 16 to ensure the hydraulic sealing of the closing cap 16 on the open end 12.
  • the sealing means 32 comprise, in one piece therewith, a membrane 36 delimited by a peripheral edge 40, wherein the membrane 36 is facing the closure portion 20 of the closing cap 16.
  • the perimetral lip 40 comprises a raised perimeter 42 which constitutes a perimetral thickening of said membrane 36.
  • peripheral lip and/or raised perimeter 40 is influenced in compression between the closing cap 16 and the open end 12 and realizes the hydraulic seal of the closing cap 16.
  • the membrane 36 and the perimetral lip 40 are removably laid on the closing cap 16 without the interposition of gluing means.
  • the raised perimeter 42 is an O-ring, in one piece with the membrane 36.
  • said membrane 36 is an elastic membrane, in one piece with said perimetral lip or raised perimeter 40, 42.
  • said sealing means 32 consist of a gasket made of polymeric material, such as an EPDM rubber, a VITON rubber or a silicone rubber.
  • the membrane 36 may be a cap applied to the closing cap 16.
  • the membrane 36 may also comprise a washer made of plastic or another rigid material.
  • the closure portion 20 is concave towards the open end 12 so as to penetrate at least partially into said open end 12 and to achieve a centring of the closing cap 16 on the open end 12 of the radiator element 4.
  • an interspace 44 or clearance is present, fluidically separate from the fluid of the radiator element 4.
  • the membrane 36 is in contact with the closure portion 20; in other words there is clearance or there are interspaces between the membrane 36 and the closure portion 20.
  • the membrane 36 has a convex shape towards the inside of said open end 12.
  • the perimetral lip 40 is positioned inside the open end 12 of the radiator element 4 so as to abut against an inner side wall 48 of said open end 12, lapped by the fluid.
  • the closure portion 20 of the closing cap 16 has at least a perimetral seat 52 formed by a radial restriction, said perimetral seat 52 housing the perimetral lip 40 of the membrane 36 and supporting it against the inner side wall 48 of said open end 12.
  • the open end 12 has a substantially conical flaring 56 at least partially counter-shaped relative to the closure portion 20 of the closing cap 16, said perimetral lip 40 stopping in abutment against the flaring 56 from the side of said inner side wall 48 of the open end 12.
  • the perimetral lip 40 abuts in compression between the closing cap 16 and the front edge 28.
  • Such edge may also have a raised perimeter 42.
  • the open end 12 comprises a protuberance 60 at an outer side wall 64 of the open end 12, said protuberance 60 defining an undercut 68 for the gripping of the coupling collar 24 of the closing cap 16.
  • perimetral lip or raised perimeter 40,42 abuts against said protuberance 60 at the outer side wall 64 of the open end 12, so as to be compressed between the protuberance 60 and the coupling collar 24.
  • said protuberance 60 has a frusto-conical shape that tapers towards the associable closing cap 16 and the perimetral lip or raised perimeter (40, 42) abuts against a frusto-conical portion 72 of the protuberance 60.
  • the radiator element according to the invention makes it possible to overcome the drawbacks of the prior art.
  • the cap according to the present invention may be hooked to the relative end without inaccuracies or burrs from welding and virtually no waste.
  • the cap after being hooked, can be painted directly with excellent results because the paint does not need to cover inaccurate and irregular surfaces such as those obtained by welding.
  • the bending of the cap collar takes place in a uniform and gradual manner thanks to the simultaneous action of a plurality of jaws arranged preferably in steps.
  • the seal provided avoids a direct contact between the ends of radiator element and the closing cap at the part lapped by the water, so as to avoid the occurrence and propagation of galvanic currents and consequent corrosion phenomena.
  • the gasket in elastomeric material also avoids the occurrence of noise and chafing due to different shrinkage between the end of the radiator element and the cap resulting from different thermal expansion coefficients.
  • the seal prevents direct contact between the water and relative debris (e.g. limestone) with the inner part of the cap which is therefore not subject to mechanical abrasion.
  • water and relative debris e.g. limestone
  • the inner gasket is housed on the closing cap without being glued to its inner wall: this way during assembly the gasket is not subjected to excessive radial stresses and possible cracking.
  • the gasket can adapt to the geometry of the cap and the end of the radiator element, i.e. the geometry of the interspace which is created between the end of the radiator element and the closing cap.
