Description
- This invention relates to heat exchangers of the type having a header plate supporting the open ends of a plurality of tubes and a tank secured to the header plate.
- The efforts by the automotive industry to reduce the weight of vehicles have brought about an increasing use of non-metallic materials in various parts of vehicles. Heat exchangers, more commonly termed radiators, are no exception. While metal materials are still employed in the cores for such heat exchangers because of their greater thermal conductivity over plastics, other heat exchanger components that do not require good thermal conductivity are being made of plastic. A primary example is the so-called tank which is fitted to the heat exchanger core, typically by securement to the header plates which define the ends of such cores.
- Because the joint between the header plate and the tank is one of dissimilar materials, prior techniques of brazing or soldering the joint can no longer be employed. In lieu thereof, to effect the necessary seal, a gasket is disposed between the tank and the header plate and any of a variety of means are employed to hold the components in assembled relation with the gasket under compression to assure a seal at the operating pressures for which the heat exchanger was designed.
- It is, of course, necessary that the means employed to effect the connection be strong and long lived to prevent leakage. At the same time, it is desirable that the means be such that disassembly of the component parts can be effected when required for servicing. It is also desirable that the means utilized lend themselves to use in mass production to minimize cost.
- Attempts to achieve these objects have resulted in proposals wherein a header plate is provided with a peripheral groove in which the gasket to be compressed may be disposed. The tank is provided with a peripheral flange sized to be received in the groove and adapted to compress the gasket therein. The outerwall of the groove is then deformed in part to overlie the flange on the tank and hold the same in a position compressing the gasket. This approach is exemplified by US-A-4 331 201 which discloses the features according to the precharacterising part of claim 1.
- Unfortunately, because this approach involves deformation of a metal wall which necessarily may be sufficiently thin as to be easily deformed, the same may not always be as strong as might be desired. Pressure within the system during operation will act against the deformed material and tend to deform it back toward its original configuration. When such occurs, the compressive forces exerted on the gasket are lessened and leakage may occur.
- According to the present invention there is provided a heat exchanger comprising : a metal header plate supporting the open ends of a plurality of tubes; a gasket receiving area extending about the periphery of said header plate and having a bottom wall surrounded by an upstanding deformable side wall terminating in an edge ; a compressible gasket in said gasket receiving area ; a plastics tank having an opening surrounded by an outwardly extending flange, said flange being sized and configured to be fitted within said gasket receiving area with one side of the flange abutting said gasket and another side of the flange within said area and spaced from said side wall edge, said tank compressing said gasket so that said gasket effects a seal between said tank and said header plate ; and a plurality of tabs in said side wall overlying said another side to hold said tank in compressing relation to said gasket, each said tab being formed by deformation and piercing of said side wall after said flange has been fitted within said gasket receiving area to have a nominally planar, free edge displaced from said side wall and in contact with said another side of said flange, characterised in that each said tab is located below the side wall edge and tapers from said free edge toward said side wall edge to merge into said side wall on all sides of said tab except that defining the free edge prior to or at said side wall edge and that said side wall in the area of said tabs and above said free edge is deformed towards said tank to at least overlie said flange to assure abutment of said free edges with said another side.
- The chosen configuration of the tabs provides excellent force distribution to the side wall of the gasket receiving area or groove so as to provide excellent resistance to deformation back toward the original shape. At the same time, the tabs are easily formed according to mass production techniques and, where necessary, may be intentionally deformed back to their original configuration to allow disassembly of the components.
- Preferably, each tab is generally part eggshaped, or part spherical.
- The tabs may be formed in the side wall by punching or piercing. No restraint is placed on the portion of the side wall wherein the tabs are formed such that such portion may be slightly bent toward the tank. Thereafter the sidewall is rolled or bent from the vertical to partially overlie the flange such that the free edges of the tabs are parallel to the upper surface of the flange.
- The invention will be better understood from the following description or a preferred embodiment thereof, given by way of example only reference being had to the accompanying drawings, wherein :
- Fig. 1 is a perspective view of a tank assembled to a header plate by a connection made according to the invention ;
- Fig. 2 is a fragmentary, enlarged elevation of the assembly ;
- Fig. 3 is a further enlarged, sectional view taken approximately along the line 3-3 in Fig. 2 ; and
- Fig. 4 is a fragmentary enlarged view of the header plate with a tab formed therein but with the tank removed for clarity.
- An exemplary embodiment of the invention is illustrated in the drawing and with reference to Figs. 1 and 3 thereof, is seen to include a
radiator tank 10, typically formed of plastic, and aheader plate 12 formed of metal. Conventionally, theheader plate 12 receives the open ends 14 of a plurality of tubes 16 (only one of which is shown). Thetank 10 has anopening 18 which is surrounded by an outwardly directedflange 20 having upper andlower sides more coolant ports 26 are provided for thetank 10. As best seen in Fig. 3, theheader plate 12, at its periphery, includes a groove, generally designated 28. Thegroove 28 is defined by an upstanding,outer side wall 30, abottom wall 32 and an inner wall 34 generally parallel to theouterwall 30 which merges with the main body of theheader plate 12 by means of around 36. As can be seen, thegroove 28 andflange 20 are sized and configured so that the latter may be received in the former. - A
compressible gasket 40 is disposed in thegroove 28 in abutment with the bottom wait 32 thereof and thetank 10 oriented so that theflange 20 may be introduced into thegroove 28. Upon introduction of theflange 20 into the groove, thesurface 24 is brought into abutment with thegasket 40 and continued urging of thetank 10 toward theheader plate 12 will result in thegasket 40 being compressed to the desired degree. In the usual case, somewhat more than the desired compression force will be placed on the components to allow a series oftabs 42 to be deformed from thewall 30 to overlie thesurface 22 of theflange 20. When thetabs 42 have been formed, the compressive force may be released and the structure will assume the configuration illustrated in Fig. 3. - To assure good retentive strength and a resistance to deformation in response to pressure within the
tank 10, thetabs 42 have the shape of one quadrant of a sphere or an egg. They include a curved low-erfree edge 44 which is nominally planar and overlies and abuts thesurface 22 of theflange 20. Thetabs 42 gradually taper from t heir edges 44 toward theouter side wall 30 toline 46. Generally, theedge 48 of thesidewall 30 is reached such that a space 50 exists between theedge 48 and thetab 42. - The tabs may be formed in one single operation with an appropriate shaped tool which effectively pierces the
outer wall 30 to define afree edge 44 while deforming a portion of thewall 30 to define the body of thetab 42. This forming process is readily adaptable to mass production techniques. - To simplify the assembly operation, and to minimize the tooling required, the
upper portion 52 of theside wall 30 wherein thetabs 42 are formed is not restrained oppositely of the advancing punching or piercing tool during the punching or piercing operation. This in turn may result in theupper portion 52 of theside wall 30 being slightly bent toward thetank 10. - Because the
tabs 42 are formed by deforming metal, metal flow during the forming operation may result in thefree edges 44 of the tabs being increasingly spaced from the upper surface of theflange 20 in the direction away from theside wall 30 and toward thetank 10. Consequently, to bring the entire extent of eachfree edge 44 into contact with the upper surface of theflange 20, following the operation wherein thetabs 42 are formed. The invention contemplates that theupper portion 52 of the side wall may be further bent along aline 54 approximately at the level of thefree edges 44 in the direction of thetank 10. As a consequence, theupper portion 52 of theside wall 30 will remain upstanding but will partially overlie theflange 20 and thefree edges 44 will be parallel to and abut the upper surface of the flange 50. The bending operation can be performed by any suitable process as, for example, by rolling. In a preferred embodiment, theupper portion 52 is bent approximately 30° from the vertical toward thetank 10. - It will be appreciated that when necessary, the
tabs 42 may be deformed back to their original shape if, for any reason, it is necessary to remove the tank 1 from the remainder of the assembly. In this regard, it is desirable that thetabs 42 or theupper portion 54 of theside wall 30 do not extend inwardly to be in contact with aside wall 56 of thetank 10 so as to allow insertion of a tool to accomplish such deformation. - Finally, it will be appreciated that the geometry of the
tabs 42 assures that forces tending to separate thetank 10 from theheader plate 12 will be evenly distributed to theouter wall 30 to resist deformation of the same that could result in release of compressive force on thegasket 40 that could in turn result in leaks. The free edges 44 provide a substantial zone of contact with theflange surface 22 and such forces as are placed against theedges 44 are distributed to the remainder of therespective tab 42 which will be placed in compression without an appreciable bending moment applied thereto. Consequently, an extremely reliable and easily formed connection is provided by the invention.
