Definitions

  • the invention relates to a heat exchanger which can be used in particular as an oil radiator for cooling the lubricating oil of a motor vehicle, in particular of a heavy vehicle.
  • the plates and the fins are usually joined together by brazing and there are further provided two housings fixed directly on an end plate to allow the entry and exit of the fluid to cool, usually oil.
  • Such a known heat exchanger is usually fixed to the vehicle by fixing means brazed to the flat tubes.
  • the object of the invention is in particular to overcome this drawback.
  • a heat exchanger of the aforementioned type which comprises an elongated cross member applied against a plate located at one end of the stack, provided with two passages communicating respectively with the two series of aligned openings and having a deformable shaped part expansion lyre to allow a change in its length, as well as two brackets at right angles to the crosspiece and bearing against the plate located at the other end of the stack.
  • the cross member and the two square flanges tightly surround the stack of flat tubes, whatever the temperatures of the fluid entering and leaving the heat exchanger.
  • the expansion lyre presented by the cross-member allows, by spring effect, to exert an excellent contact on the flat tubes in order to have a good brazing.
  • the cross member comprises a flat rectangular flange having a transverse U-shaped fold constituting the aforementioned expansion lyre.
  • the length of the flange can be modified, either in the direction of increase, or in the direction of decrease.
  • the cross member has two opposite lateral edges extending perpendicular to the plane of the flange and serving for fixing the two angle flanges.
  • the cross member further comprises at least one longitudinal edge extending perpendicular to the plane of the flange and serving for fixing the heat exchanger.
  • each square flange comprises a first branch extending parallel to the direction of the stack and bearing against the ends of the plates and a second branch extending parallel to the cross member and pressing against the plate located at the other end of the stack.
  • the square and the two flanges thus form a frame surrounding the stack of flat tubes.
  • the first branch of one of the flanges advantageously comprises a fixing wing folded at a right angle.
  • This wing can be used for fixing the heat exchanger in the motor vehicle.
  • the respective second branches of the two flanges terminate respectively in two adjacent oblique edges. Two independent flanges are thus produced for which the interval between the two adjacent oblique edges can vary.
  • the two respective branches of the two flanges are joined together by means of an expansion lyre.
  • the two flanges are integral with one another.
  • the heat exchanger comprises two housings attached to the cross member, respectively opposite the two passages and provided respectively with an inlet pipe and an outlet pipe for the fluid.
  • the two boxes can be provided beforehand on the cross member, which then facilitates the assembly of the cross member and the two flanges on the flat tubes.
  • the flat tubes, the fins, the cross member and the flanges are brazed together.
  • the heat exchanger of the invention comprises a multiplicity of flat tubes 10 arranged juxtaposed to form a stack in a stacking direction XX ( Figure 2).
  • Each of the flat tubes 10 is formed by two opposite elongated plates 12 delimiting between them a blade 14 for circulating a fluid, for example lubricating oil of an engine or oil of the gearbox of a motor vehicle, for example of a heavy vehicle.
  • Each of the blades 12 has a generally rectangular shape and has a peripheral edge 16 forming an assembly lip to allow the tight connection with a similar plate located opposite.
  • Each of the plates 12 has two bosses 18 and 20 provided respectively in two opposite regions of the plates, said regions being spaced apart in the longitudinal direction of the plates.
  • the bosses 18 and 20 constitute plate heads and are provided with an opening 22 and an opening 24 respectively.
  • each of the openings 22, as well as each of the openings 24, is a double opening but it could be a single opening.
  • the openings 22 are aligned with each other in the direction XX and allow the fluid to enter the blades 14. This fluid then leaves the blades 14 through the openings 24 which, too, are aligned with each other in the direction XX.
  • each of the blades 14 is placed a disturbing element 25 (shown only in FIG. 1) to disturb the flow of the fluid flowing in the blades and improve the heat exchange with the air.
  • the heat exchanger further comprises a multiplicity of corrugated fins 26 interposed between the flat tubes 10 and adapted to be swept by an air flow passing between the flat tubes 10.
  • the fins 26 have a generally rectangular shape and they are 'each extend between the bosses 18 and 20. They have substantially the same width as the tubes 10 but have a shorter length.
  • the heat exchanger as just described so far has a structure in itself known.
  • the plates 12 forming the flat tubes 10 and the fins 26 are assembled by brazing.
  • the heat exchanger comprises an elongated cross member 28 applied against that of the plates 12 located at the upper end of the stack.
  • the cross member 28 comprises a rectangular flange 30 of generally planar shape having substantially the same dimensions as the plate 12.
  • the rectangular flange 30 bears against the two bosses 18 and 20 of the corresponding plate 12.
  • the rectangular flange 30 has a transverse fold 32 with a U-shaped or omega-shaped section which constitutes a lyre of dilation allowing a modification of the length of the flange 30, either in the direction of increase, or in the direction of decrease.
  • each of the passages is formed by a double contour opening similar to that of the double openings 22 and 24, respectively.
  • the cross member 28 further comprises two opposite lateral edges 38 and 40 extending perpendicular to the plane of the flange 30 and serving respectively for the fixing of two flanges 42 and 44 in the form of brackets.
  • the cross member 28 further comprises a longitudinal edge 46 extending perpendicular to the plane of the flange 30 and used for fixing the heat exchanger.
  • the flange 46 has a buttonhole 48.
  • the cross member 28 also has a longitudinal flange 47 extending over part of the length of the flange.
  • the flange 42 comprises a first branch 50 extending parallel to the direction XX of the stack and coming to bear against the ends of the plates as well as a second branch 52 extending parallel to the flange 30 of the cross member and pressing against the plate 12 located at the other end of the stack.
  • the flange 44 comprises a first branch 54 extending parallel to the direction XX and coming to bear against the ends of the plates and a second branch 56 extending parallel to the flange 30 and pressing against the plate located at the other end, or lower end, of the stack.
  • the first branch of the flange 44 comprises a fixing wing 58 bent at a right angle and provided with two oblong holes 60.
  • the respective second branches 52 and 56 of the two flanges end respectively by two adjacent oblique edges 62 and 64 separated by a small interval.
  • This interval can increase or decrease according to the differences in expansion undergone by the flat tubes 10 as a function of the inlet and outlet temperatures of the fluid passing through them.
  • the two branches 52 and 56 could be joined together by a dilatation lyre similar to the lyre 32 described above.
  • the heat exchanger also comprises two housings 66 and 68 (FIG. 1) each formed from a stamped sheet metal and attached to the flange 30 of the cross member respectively opposite the two passages 34 and 36.
  • the housings 66 and 68 are provided respectively an inlet pipe 70 and an outlet pipe 72 for the fluid, for example oil, intended to be cooled.
  • the assembly constituted by the cross member 28 and the two flanges 42 and 44 constitutes a kind of frame which comes to tightly surround the stack of flat tubes 10 and fins 26, whatever the expansions undergone by the assembly in function differences in fluid temperature between the inlet and outlet of the heat exchanger.
  • the flat tubes 10 plates 12
  • the fins 26, the cross member 28 and the flanges 42 and 44 are advantageously joined together by brazing.
  • the heat exchanger of the invention is very particularly intended for the cooling of the lubricating oil of the engine or of the gearbox of a motor vehicle, in particular of a heavy vehicle.
