Definitions

  • 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; and more specifically, to an improved connection between the tank and the header plate.
  • Heat exchangers more commonly termed radiators
  • 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 tanks which are fitted to the heat exchanger core most typically by securement to the header plates which define the ends of such cores.
  • 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.
  • 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 outer wall 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.
  • the present invention is directed to overcoming one or more of the above problems.
  • An exemplary embodiment of the invention achieves the foregoing object in a structure including a metal header plate supporting the open ends of a plurality of tubes and provided with a gasket receiving area extending about the periphery of the header plate.
  • the area has a bottom wall surrounded by a deformable side wall terminating in an edge.
  • a compressible gasket is disposed in the area and a tank having an opening surrounded by an outwardly extending flange is provided.
  • the flange is sized and configured to be fitted within the area with one side of the flange abutting the gasket and the opposite side of the flange being disposed within the area and spaced from the edge.
  • the tank compresses the gasket so that the gasket effects a seal between the tank and the header plate.
  • a plurality of tabs are disposed in the side wall below the edge and overlie the opposite side of the flange to hold the tank in compressing relation to the gasket.
  • Each of the tabs is formed by deformation of the side wall to a generally nominally planar, free edge displaced from the side wall and in contact with the opposite side of the flange.
  • Each such tab tapers from the free edge toward the side wall edge to merge into the side wall prior to or at the side wall edge.
  • the gasket receiving area is defined by a groove.
  • the invention also contemplates that the tabs merge into the side wall at locations spaced from the side wall edge.
  • the side wall is deformed toward the tank to at least partially overlie the flange.
  • each of the tabs is generally egg shaped or spherically shaped.
  • 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.
  • 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.
  • 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 side wall 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.
  • FIG. 1 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 a header plate 12 formed of metal.
  • the header plate 12 receives the open ends 14 of a plurality of tubes 16 (only one of which is shown).
  • the tank 10 has an opening 18 which is surrounded by an outwardly directed flange 20 having upper and lower sides 22 and 24, respectively.
  • One or more coolant ports 26 are provided for the tank 10.
  • the header plate 12 at its periphery, includes a groove, generally designated 28.
  • the groove 28 is defined by an upstanding, outer side wall 30, a bottom wall 32 and an inner wall 34 generally parallel to the outer wall 30 which merges with the main body of the header plate 12 by-means of a round 36.
  • the groove 28 and flange 20 are sized and configured so that the latter may be received in the former.
  • a compressible gasket 40 is disposed in the groove 28 in abutment with the bottom wall 32 thereof and the tank 10 oriented so that the flange 20 may be introduced into the groove 28.
  • the surface 24 is brought into abutment with the gasket 40 and continued urging of the tank 10 toward the header plate 12 will result in the gasket 40 being compressed to the desired degree.
  • somewhat more than the desired compression force will be placed on the components to allow a series of tabs 42 to be deformed from the wall 30 to overlie the surface 22 of the flange 20.
  • the compressive force may be released and the structure will assume the configuration illustrated in Fig. 3.
  • the tabs 42 have the shape of one quadrant of a sphere or an egg. They include a curved lower free edge 44 which is nominally planar and overlies and abuts the surface 22 of the flange 20. The tabs 42 gradually taper from their edges 44 toward the outer side wall 30 to line 46. Generally, the edge 48 of the sidewall 30 is reached such that a space 50 exists between the edge 48 and the tab 42.
  • the tabs may be formed in one single operation with an appropriate shaped tool which effectively pierces the outer wall 30 to define a free edge 44 while deforming a portion of the wall 30 to define the body of the tab 42. This forming process is readily adaptable to mass production techniques.
  • the upper portion 52 of the side wall 30 wherein the tabs 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 the upper portion 52 of the side wall 30 being slightly bent toward the tank 10.
  • the tabs 42 are formed by deforming metal, metal flow during the forming operation may result in the free edges 44 of the tabs being increasingly spaced from the upper surface of the flange 20 in the direction away from the side wall 30 and toward the tank 10. Consequently, to bring the entire extent of each free edge 44 into contact with the upper surface of the flange 20, following the operation wherein the tabs 42 are formed, a highly preferred embodiment of the invention contemplates that the upper portion 52 of the side wall may be further bent along a line 54 approximately at the level of the free edges 44 in the direction of the tank 10. As a consequence, the upper portion 52 of the side wall 30 will remain upstanding but will partially overlie the flange 20 and the free 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, the upper portion 52 is bent approximately 30° from the vertical toward the tank 10.
  • the tabs 42 may be deformed back to their original shape if,- for any reason, it is necessary to remove the tank 10 from the remainder of the assembly.
  • the geometry of the tabs 42 assures that forces tending to separate the tank 10 from the header plate 12 will be evenly distributed to the outer wall 30 to resist deformation of the same that could result in release of compressive force on the gasket 40 that could in turn result in leaks.
  • the free edges 44 provide a substantial zone of contact with the flange surface 22 and such forces as are placed against the edges 44 are distributed to the remainder of the respective 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.
