Definitions

  • the invention concerns a head collecting tank, designed especially for the tubular heat exchanger of a motor vehicle.
  • a heat exchanger consisting of a tubular heat exchanging part, connected by each of its ends to a tube panel, each of which is fastened to one head collecting tank.
  • Each head collecting tank is provided with an inner end in the form of a right parallelogram, on which the tube panel is secured across a sealing element.
  • the tube panel is formed by a frame part with a set of mutually parallel braces, having in cross section the shape of the letter U and passing at their ends into the frame part, which also has the shape of the letter U in cross section with an elongated arm at the side away from the braces.
  • a head collecting tank designed especially for the tubular heat exchanger of a motor vehicle, provided with an inner end in the form of a right parallelogram, on which is secured across a sealing element a tube panel, for mounting and securing of one of the lengthwise ends of a bundle of tubes of the exchanger, formed by a frame part with a set of mutually parallel braces having in cross section the shape of the letter U and passing into the frame part, which also has in cross section the shape of the letter U with an elongated arm on the side away from the braces, according to this invention, whose essence lies in the fact that the thickness of the wall of each brace of the tube panel, bounding longitudinally the space for one of the longitudinal ends of the tube bundle of the exchanger, is larger than the thickness of the wall of the frame part of the tube panel transversely bounding the space for one of the longitudinal ends of the tube bundle of the exchanger, and the inner end of the head collecting tank has projections on its two opposite facing inner walls project
  • the frame part has both of its parallel inner walls, parallel to the braces, provided with at least two creases to form ribs
  • the tube panel has the elongated outer arms of its frame part provided, along the entire circumference and in one plane parallel with the peripheral edge, with a series of openings for clamping by forming excess material left above them into a shoulder on the head collecting tank when the tube panel is joined to the head collecting tank.
  • An additional embodiment of the invention is that the frame part and the braces have lines drawn through the bottoms in their lowest places situated in the same plane, while the frame part has a vertical distance between its arms, in the region of their transition to the curved part, equal to the diameter of the sealing element.
  • An additional embodiment of the invention is that the wall of the frame part bounding the space formed between two braces for one of the longitudinal ends of the tube bundle of the exchanger has its height, measured from its highest edge to its transition into the curved part, greater than half the diameter of the sealing element.
  • a particular embodiment of the design of the head collecting tank is that it prevents a loss of tightness thanks to uniform deformation of the sealing element in the bounded space and thanks to elimination of free play between the edge of the inner end of the head collecting tank and the frame part of the tube panel.
  • FIG. 1 illustrates a heat exchanger having a head collecting tank with a tube panel arranged on both sides of the tube bundle;
  • FIG. 2 is an axonometric view of the tube panel on the side with the head collecting tank;
  • FIG. 3 is an axonometric view of a cross section of the tube panel through the middle of the space bounded by two neighboring braces;
  • FIG. 4 is an axonometric view of a cross section of the tube panel through the bottom of one of its braces, with a sealing element placed in its frame part;
  • FIG. 5 is a view of part of the tube panel on the side with the head collecting tank with three creases for forming ribs on the inner side of the shorter frame part;
  • FIG. 6 is a cross section of the connection of the tube panel to the head collecting tank at the site of formation of a projection extending on the inner side of the head collecting tank beyond its outer edge.
  • FIG. 1 shows a tubular heat exchanger for a motor vehicle, whose tubular body is joined at both of its opposite ends across a tube panel 4 to a head collecting tank 1 .
  • the tube panel 4 (see FIG. 2 ) is formed by an extruded metal piece, having a rectangular frame part 5 with a set of mutually parallel braces 6 , having in cross section the shape of the letter U and passing into the frame part 5 , which also has in cross section the shape of the letter U with an elongated arm on the side away from the braces 6 .
  • the elongated arms of the frame part 5 are provided, along the entire circumference and in one plane parallel with the peripheral edge, with a series of openings 9 for clamping by forming excess material left above them into a shoulder on the head collecting tank 1 when the tube panel 4 is joined to the head collecting tank 1 (see FIG. 6 ).
  • a sealing element 3 having a circular profile in cross section in the present example (see FIG. 4 ) is placed on the bottom of the frame part 5 .
  • the thickness of the wall of each brace 6 bounding longitudinally the space for one of the longitudinal ends of the tube bundle of the exchanger, is larger than the thickness of the wall of the frame part 5 transversely bounding the space for one of the longitudinal ends of the tube bundle of the exchanger.
  • the inner end 2 of the head collecting tank 1 has projections 7 on its two opposite facing inner walls (see FIG. 6 ) extending beyond its outer edge and each one arranged opposite each transition of the longitudinal cavity of the brace 6 to the cavity of the frame part 5 . These projections 7 stabilize the sealing element 3 in the desired space between the tube panel 4 and the head collecting tank 1 while enabling a precise delimiting of the position of the tube panel 4 on the inner end 2 of the head collecting tank 1 ,
  • the frame part 5 (see FIG. 5 ) has both of its inner walls, parallel to the braces 6 , provided with at least two creases to form ribs 8 for a better and more compact joining of the tubular body of the exchanger to the frame part 5 .
  • the frame part 5 and the braces 6 have lines drawn through the bottoms in their lowest places situated in the same plane. Moreover, the frame part 5 has a vertical distance between its arms, in the region of their transition to the curved part, equal to the diameter of the sealing element 3 , while the wall of the frame part 5 bounding the space formed between two braces 6 for one of the longitudinal ends of the tube bundle of the exchanger has its height, measured from its highest edge to its transition into the curved part, greater than half the diameter of the sealing element 3 (see FIG. 3 ).
