Definitions

  • the invention relates to a heat exchanger with a tube bundle and plastic fluid boxes, in particular a radiator for the cooling of a truck engine.
  • heat exchangers of the type comprising a bundle of parallel tubes and, at at least one end thereof, a plastic fluid box, the ends of the tubes entering the fluid box in a liquid-tight manner by holes made in a wall of the fluid box forming a manifold, and further comprising at least one mounting cross member extending parallel to the tubes and fixed respectively to one end of the fluid box, in an offset region, in the direction longitudinal of the tubes and towards the median transverse plane thereof, relative to the manifold.
  • the fluid box has a flange on which are fixed, on the one hand, the manifold and on the other hand, intermediate parts used for mounting the cross member, the fixing of said intermediate parts made by claws or legs folded over the edge of the water box.
  • the assembly of the heat exchanger is complicated since it is necessary to fix the intermediate parts between each fluid box and each crosspiece.
  • the fluid boxes must be of a very specific type in which the collector is an independent piece which has just been attached and fixed on the peripheral edge of the fluid box.
  • the bottoms which form the ends of the fluid boxes extend perpendicular to the longitudinal direction of the fluid box, that is to say parallel to the longitudinal direction of the tubes. . It follows that the size of the heat exchanger in the plane defined by the longitudinal direction of the tubes and the longitudinal direction of the fluid boxes is substantially that of a rectangle. Consequently, the width of the heat exchanger, i.e. its dimension in the longitudinal direction of the fluid boxes, remains constant over its entire height, i.e. over its extent in the direction longitudinal of the tubes.
  • the object of the invention is to provide a heat exchanger allowing particularly simple mounting of the cross member (s) on each fluid box, regardless of the type of fluid box used.
  • Another object of the invention is to provide a heat exchanger structure allowing a reduction in local width.
  • the assembly of the heat exchanger is much simpler.
  • the rigidity of the heat exchanger is increased due to the fact that the bases and the ribs are integral with the fluid box.
  • the base extends parallel to the tubes and is connected to the fluid box by two parallel ribs.
  • these ribs have the shape of a right triangle.
  • the invention applies to any type of plastic fluid box, in particular to those comprising a tubular wall including a manifold-shaped portion.
  • a tubular wall including a manifold-shaped portion.
  • one end of the tubular wall, which forms the bottom is molded, while the other end is open to receive a bottom cover.
  • the invention also applies to fluid boxes in which the two end bottoms have come from molding and in which the collector consists of another piece of plastic material which is attached and fixed, for example by welding, to the rest of the fluid box.
  • the invention can also be applied to fluid boxes in a single section or in two sections.
  • each fluid box consist of funds extending obliquely so that the length of the fluid box is less in its longitudinal zone opposite to the collector than in the longitudinal zone of the collector, which makes it possible to locally reduce the overall dimensions in width of the heat exchanger.
  • the radiator shown in Figure 1 has, seen from the front according to Figure 1, the general shape of a rectangle whose sides extend vertically and horizontally. It essentially comprises a bundle of parallel tubes 1 directed vertically and regularly distributed in several rows over the width of the radiator. To simplify the drawing, only two tubes 1 are shown in Figure 1 in the vicinity of one of the vertical edges of the radiator. The ends of the tubes 1 open into fluid boxes, for example water boxes, of generally tubular shape 2-1, 2-2, extending respectively along the upper and lower horizontal sides of the radiator.
  • Each of the fluid boxes is, in the example, formed of two tubular sections 20 molded from plastic and assembled together by welding.
  • Each tubular section 20 which is molded in one piece has, as shown in Figures 2 and 3, a tubular wall 21, a bottom 22 closing one end of the wall 21, an assembly base 23 extending parallel to the tubes 1 and two ribs 24 connecting the base 23 to the tubular wall 21.
  • These two ribs are parallel and have the shape general of a right triangle (figure 2).
  • the end 25, opposite the bottom 22, of the tubular wall is open.
  • Two sections 20 are welded to each other by friction through their end faces 26 surrounding the opening 25, thus producing a tubular fluid box closed at its two ends by the oblique bottoms 22.
  • the tubular wall 21 of each fluid box comprises a flat wall portion 27 forming a manifold, crossed in a liquid-tight manner by the ends of the tubes 1 in a manner known per se.
  • the oblique bottoms 22 are oriented so that the length of the fluid box, that is to say the width of the radiator, decreases from the plane of the collector towards the part opposite the latter of the tubular wall. 21, that is to say towards the upper or lower end of the radiator. The angles of these are therefore chamfered, which facilitates its accommodation in the vehicle body.
  • the bases 23 of the tubular sections 20 serving to assemble them to profiled crosspieces 3 extending along the vertical sides of the radiator.
  • Each cross member 3 comprises a back 30 forming the corresponding lateral face of the radiator and two wings 31 extending along the main faces thereof.
  • the crosspieces 3 serve to reinforce the structure of the radiator and to mount it on the vehicle by means of lugs 41 and 42 which are fixed to it.
  • the internal face of the backs 30 rests on horizontal ribs 50 and vertical ribs 51 belonging to the base 23 and defining, by their vertices, a support plane 52 for the crosspieces (FIGS. 2 and 3).
  • the support plane 52 is perpendicular to the longitudinal direction fluid boxes, therefore parallel to the longitudinal direction of the tubes 1.
  • Each base 23 is crossed by four holes 53 surrounded by bosses 54 which terminate in the support plane 52.
  • These holes 53 and corresponding holes made in the back crosspieces allow the assembly of the latter to the fluid boxes by assembly elements 6 such as rivets or screws for example.
  • each base 23 is offset, relative to the tubular wall 21, in the direction of the median transverse plane M of the tubes 1 ( Figure 1). More specifically, the base is on the side of the plane M with respect to the plane of the manifold 27. Ribs 24 extending substantially along the two main faces of the radiator respectively ensure a rigid connection of the base to the tubular wall 21. Each rib 24 has the shape of a right triangle of which one side of the right angle coincides with a vertical side of the base and the other of which corresponds to a part of the longitudinal side of the manifold. The hypotenuse of the right triangle forms a free side of the rib.
  • the fluid boxes 2-1 and 2-2 are linked to each other in their central region by two tie rods 55 passing through holes made in bosses 56 provided on the tubular walls of the tubular sections 20.
  • These tie rods 55 support the longitudinal forces due to the tendency of the fluid boxes to bend when the radiator is full of pressurized fluid, and thus prevent tearing forces being exerted on the welds of the ends of the tubular sections.
  • One of the ends 57 of each tie rod is folded at a right angle and rests on a boss 56, while the opposite end 58 is threaded and cooperates with a nut 59 which is tightened on another boss 56.
  • heat exchangers comprising one or two crosspieces.
