Description
- The present invention relates to a radiator element according to the preamble of claim 1. Such an element is known from
WO2007/138627 A1 . - In particular, 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.
- In the radiator elements of the prior art, 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.
- This solution is extremely slow and expensive to perform and involves high material wastage due to welding inaccuracies. Moreover, after welding burrs inevitably occur which among other things worsen the aesthetics of the element and determine inaccuracies in the subsequent painting operation of the radiator element.
- In order to avoid such drawbacks, it is also known of in the art to make caps which are directly hooked to the open end of the radiator element, after the insertion of a sealing element or gasket.
- Such solutions, however, have some further drawbacks. In fact, over time and with the different thermal expansions between the end of the radiator element (usually made of aluminium to improve the thermal exchange with the external environment) and the cap (usually made of steel since more robust) there may be leakages of liquid (typically water).
- Such leakages are harmful because they can cause serious damage to the environment where the radiator is situated, such as flooding.
- There is thus the problem of having to ensure over time the absolute tightness of the join between the cap and the end of the radiator element. This tightness is ensured, as seen, by the sealing gasket alone interposed between the end and the cap and is devoid of any welding: it follows, as seen, that such tightness is extremely critical and difficult to ensure over time.
- There is lastly a further technical problem related to the fact that in the solutions with steel caps it is necessary to prevent the water inside the radiator element from coming into contact with the inner steel wall of said cap. This is because there may be corrosion due to galvanic currents (i.e. electric currents of low intensity, generated by the electric potential difference between two different materials in contact with each other), with consequent chemical corrosion of the cap, but also the phenomena of mechanical erosion of the cap due to the rubbing action of debris (such as limestone) carried in suspension in the flow of water inside the radiator element.
- The purpose of the present invention is to make a closing cap which overcomes the drawbacks mentioned with reference to the prior art.
- Such drawbacks and limitations are resolved by a radiator element according to claim 1.
- Other embodiments of the cap according to the invention are described in the subsequent claims.

- With reference to the aforementioned figures,
reference numeral 4 globally denotes a radiator element provided with acavity 8 and suitable to be crossed by a heat exchange fluid, typically water. - According to one embodiment, the radiator element extends in a main axial direction X-X.
- Several radiator elements, joined in a battery, constitute, in the known manner, a radiator.
- For example, the
radiator element 8 may be obtained by die casting, in which thecavity 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 anopen end 12. - Said
open end 12, according to one embodiment, has a cylindrical configuration, preferably axialsymmetric with respect to the main direction X. - The
radiator element 4 comprises aclosing cap 16 facing and sealed in a watertight manner to saidopen end 12. - In particular, the
closing cap 16 is coupled according to a shaped coupling to theopen end 12, as further described below. - According to one embodiment, the
closing cap 16 has an axially symmetrical shape, preferably relative to an axis coinciding with the main axial direction X of theopen end 12 of theradiator element 4; for example saidclosing cap 16 has a circular course and is counter-shaped relative to theopen end 12 so as to occlude the same. - Preferably, the
closing cap 16 is made of galvanized or aluminized or stainless steel. - The
closing cap 16 comprises aclosure portion 20 at least partially inserted in saidopen end 12, and acoupling collar 24 at least partially folded at afront edge 28 of saidopen end 12, so as to realise the mechanical coupling between theclosing cap 16 and saidopen end 12. - Between the
open end 12 and theclosing cap 16 watertight sealing means 32 are positioned to ensure the hydraulic sealing of theclosing cap 16 on theopen end 12. - Advantageously, the sealing means 32 comprise, in one piece therewith, a
membrane 36 delimited by aperipheral edge 40, wherein themembrane 36 is facing theclosure portion 20 of theclosing cap 16. - According to one embodiment, the
perimetral lip 40 comprises a raised perimeter 42 which constitutes a perimetral thickening of saidmembrane 36. - In particular, the peripheral lip and/or raised
perimeter 40 is influenced in compression between theclosing cap 16 and theopen end 12 and realizes the hydraulic seal of theclosing cap 16. - The
membrane 36 and theperimetral lip 40 are removably laid on theclosing cap 16 without the interposition of gluing means. - According to one embodiment, the raised perimeter 42 is an O-ring, in one piece with the
membrane 36. - Preferably, said
membrane 36 is an elastic membrane, in one piece with said perimetral lip or raisedperimeter 40, 42. - For example, said sealing means 32 consist of a gasket made of polymeric material, such as an EPDM rubber, a VITON rubber or a silicone rubber.
- According to a further embodiment, the
membrane 36 may be a cap applied to theclosing cap 16. - According to a further embodiment, the
membrane 36 may also comprise a washer made of plastic or another rigid material. - According to one embodiment, the
closure portion 20 is concave towards theopen end 12 so as to penetrate at least partially into saidopen end 12 and to achieve a centring of theclosing cap 16 on theopen end 12 of theradiator element 4. - According to one embodiment, between the
membrane 36 and theclosure portion 20 aninterspace 44 or clearance is present, fluidically separate from the fluid of theradiator element 4. - According to a further embodiment, the
membrane 36 is in contact with theclosure portion 20; in other words there is clearance or there are interspaces between themembrane 36 and theclosure portion 20. - For example, in an assembled configuration, the
membrane 36 has a convex shape towards the inside of saidopen end 12. - According to one embodiment, the
perimetral lip 40 is positioned inside theopen end 12 of theradiator element 4 so as to abut against aninner side wall 48 of saidopen end 12, lapped by the fluid. - According to a possible embodiment, the
closure portion 20 of theclosing cap 16 has at least aperimetral seat 52 formed by a radial restriction, saidperimetral seat 52 housing theperimetral lip 40 of themembrane 36 and supporting it against theinner side wall 48 of saidopen end 12. - For example the
open end 12 has a substantiallyconical flaring 56 at least partially counter-shaped relative to theclosure portion 20 of theclosing cap 16, saidperimetral lip 40 stopping in abutment against the flaring 56 from the side of saidinner side wall 48 of theopen end 12. - According to a possible embodiment, the
perimetral lip 40 abuts in compression between theclosing cap 16 and thefront edge 28. - Such edge may also have a raised perimeter 42.
- According to one embodiment, the
open end 12 comprises a protuberance 60 at anouter side wall 64 of theopen end 12, said protuberance 60 defining an undercut 68 for the gripping of thecoupling collar 24 of theclosing cap 16. - For example the perimetral lip or raised
perimeter 40,42 abuts against said protuberance 60 at theouter side wall 64 of theopen end 12, so as to be compressed between the protuberance 60 and thecoupling collar 24. - Preferably 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. - As may be appreciated from the description, the radiator element according to the invention makes it possible to overcome the drawbacks of the prior art.
- In particular, thanks to the cap described it is possible to provide for the closure of open ends of radiator elements without having to perform any type of welding or brazing. Therefore there is no need for welding robots and all the inevitable wastage associated with welding operations is avoided.
- As a result, the cap according to the present invention may be hooked to the relative end without inaccuracies or burrs from welding and virtually no waste.
- Thanks to the fact that burrs do not occur, subsequent operations are not required to improve the aesthetics of the join. Furthermore, 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.
- This way the hooking of the cap is stable and safe ensuring the correct tightening of the cap on the end of the radiator element.
- Such tightening deforms the gasket which adapting to the configuration of the coupling portion of the end ensures the correct hermetic seal.
- Furthermore, 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.
- In addition, 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.
- Furthermore, 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.
- Furthermore, 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. In other words, not being mechanically fastened (for example by gluing) to the inner wall of the closing cap, 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.
- A person skilled in the art may make numerous modifications and variations to the radiator element described above so as to satisfy contingent and specific requirements while remaining within the sphere of protection of the invention as defined by the following claims.
