Definitions

  • the invention relates to a device for fixing two pipes to two adjacent openings of a heat exchanger, in particular an exchanger intended for cooling the lubricating oil of the engine of a motor vehicle.
  • the two pipes are used respectively for the inlet and outlet of a liquid, generally brine, intended for cooling the oil, which circulates in an enclosure housed at the inside the housing and generally formed by a stack of pairs of half-plates.
  • the invention particularly aims to overcome the aforementioned drawbacks.
  • the openings have a bayonet fixing configuration; the pipes respectively have bayonet ends suitable for being brought into a locking position on the openings; and the two end pieces are provided with bases shaped as a function of the spacing of the openings and having locking means capable of cooperating with each other when the end pieces are both in the locked position.
  • the attachment of the two tubes is particularly simple and rapid, since they are attached by bayonet means and that the retention of the two end pieces in the locking position is obtained by means of the locking means with which their bases are provided.
  • the device of the invention makes it possible to fix pipes of different shapes and, in particular, bent pipes of smaller size than the brazed or welded pipes in accordance with the prior art.
  • the two bayonet ends are designed to be brought into the locking position in their respective openings by rotation of a fraction of a turn in opposite directions.
  • the two bayonet ends are designed to be brought into the locking position in their respective openings by rotation of a quarter turn.
  • the base of one of the bayonet end pieces has a guiding path in an arc of a circle leading to a locking surface, while the base of the other bayonet end piece has a flexible tab having a free end which, when this other end piece is rotated, is capable of forcing against the guide track and then being housed in the locking surface, the first end piece already in the locking position .
  • the aforementioned flexible tab is non-radial.
  • the respective bases of the two bayonet ends each have a groove housing a seal capable of being compressed between the base and the housing.
  • One of the bases may have a lateral extension provided with an indexing notch which can serve, for example, to index the oil exchanger on the crankcase of the engine of the motor vehicle in question.
  • each of the tubes with its base and its bayonet tip is formed in one piece by molding a plastic material, for example of the polyamide type.
  • each of the pipes is bent, which makes it possible to reduce the overall size of the assembly.
  • FIG. 1 shows a housing 10 of a heat exchanger, in the example of a radiator for cooling the lubricating oil of an engine of a motor vehicle.
  • the housing 10 comprises a wall 12 through which two adjacent openings 14 and 16 are formed, each of which has a bayonet fixing configuration.
  • the openings 14 and 16 are intended to fix respectively two pipes 18 and 20 (FIGS. 2 and 3) attached to the housing 10.

  • a liquid such as glycol water
  • This enclosure which can for example be formed by a stack of pairs of half-plates, is traversed by oil which circulates in a closed circuit and which penetrates and leaves the enclosure at by means of two connection conduits (not shown) sealingly passing through another wall of the housing 10.
  • the openings 14 and 16 have symmetrical shapes to allow, as will be seen below, the fixing of the two pipes 18 and 20 by respective rotations, of a quarter turn each, in opposite directions.
  • the opening 16 is limited by two parallel edges 22 and 24, of unequal length, located at equal distance on either side of an axis 26. It is further limited by an edge 28 which is connected perpendicularly to the edge 22 and which extends to the axis 26. This edge 28 is extended by a edge 30 in an arc which joins with edge 24.
  • edges 22 and 24 are connected together by another edge in an arc 32 with the same radius as edge 30.
  • the two edges 30 and 32 have the same center 34, located at the intersection of the axis 26 and a perpendicular axis 36.
  • the tubing 18 which, in the example, has a bent shape at a right angle is made in one piece with a base 38 adapted to bear against the wall 12 of the housing and with a bayonet fitting 40 of configuration adapted to that of the opening 14.
  • the tubing 20 also has a bent shape at a right angle and it is made in one piece with a base 42 adapted to bear against the wall 12 outside the housing 10 and with a bayonet tip 44 of a shape adapted to that of the opening 16.
  • the ends 40 and 44 (FIG. 3) have symmetrical structures allowing the tubes 18 and 20 to be fixed by rotation of a quarter of a turn in opposite directions.
  • the establishment of the tubing 18 is effected by rotation of a quarter turn counterclockwise, from an insertion position (shown in phantom line), until 'in a locking position (shown in solid lines).
  • the tubing 20 is fixed by rotating a quarter turn clockwise, from an insertion position (shown in phantom line), to a locking position (shown in solid line). ).
  • the pipes 18 and 20 extend in directions substantially parallel to each other in their locked position.
  • the tubing 18 with its base 38 and its fixing tip is advantageously formed by molding in one piece from a plastic material, for example of the polyamide type. It is the same for the tubing 20 with its base 42 and its bayonet tip 44.
  • the bases 38 and 42 are shaped as a function of the spacing of the openings 14 and 16 and they have locking means capable of cooperating with each other when the bayonet ends 40 and 44 are both in the locking position, so as to oppose the unlocking of the two end pieces and, consequently, of the two pipes.
  • the end piece 40 of the tube 18 has an axis of rotation XX and the corresponding base 38 is produced in the form of a flat plate of generally asymmetrical shape which extends perpendicularly to the axis XX.
  • the base 38 has the general shape of a triangle limited by three straight edges 46, 48 and 50.
  • the edges 46 and 50 are joined together by an edge 52 in an arc centered on the axis XX.
  • the edges 46 and 48 are joined together by an edge 54 forming a cutout used for example for indexing on the casing of a vehicle engine.
  • edges 48 and 50 are joined together by an edge 56 in the form of an arc of a circle which, in the locking position of the tube 18, is centered on the axis of rotation X′X ′ of the tube 20 In this locking position, the edge 56 abuts against the base 42 of the tube 20 which has a generally circular shape centered on the axis X′X ′.
  • the base 38 is hollowed out over part of its thickness to form a guide track 58 in the form of an arc of a circle (FIGS. 2 to 4) which, in the locking position of the tube 18, is centered on the axis X′X ′.
  • the guide track 58 starts from the edge 50 and ends at a locking surface 60 which has the shape of a straight edge extending perpendicular to the edge 50 of the base 38 and parallel to the axis 26 of the opening 16 (in the locking position of the tubing 18).
  • the bearing surface 60 is connected perpendicularly with an abutment edge 62 extending parallel to the edge 50 of the base 38 and ending up to the edge 56.
  • the base 42 of the tube 20 comprises a flexible tab 64 ( Figures 2 to 4) which extends in a non-radial direction relative to the axis X′X ′.
  • the tab 64 ends with a free end 66 intended to cooperate with the guide track 58 and the locking surface 60 when the tube 18 has been placed in its locking position.
  • the tubing 18 is first put in place by introduction of the end piece 40 through the opening 14 and rotation of a quarter turn anti-clockwise (arrow F on Figure 2).
  • the tubing 20 is then put in place by inserting its end piece 44 through the opening 16 and by turning it a quarter turn clockwise, as shown by the arrow F ′.
  • the free end 66 of the flexible tongue 64 passes in force against the guide track 58 and comes, at the end of the race, to be housed in the blocking surface 60, while coming into abutment against the edge 62.
  • the pipes 18 and 20 are locked and the cooperation of the locking surface 60 and the flexible tongue 64 prevents any untimely unlocking of the two pipes 18 and 20.
  • each of the bases in the example the base 42, comprises an annular groove 68 centered on the axis of rotation of the nozzle, that is to say the axis X′X ′ In the example.
  • This groove is intended to accommodate an O-ring seal 70 capable of being compressed between the base and the housing to thereby ensure a tight attachment of the tubing on this housing.
  • FIGS. 7 and 8 describe more particularly the cooperation of the bayonet fitting 44 with the corresponding opening 16 of the housing, it should be noted that the configuration of the fitting 40 and the opening 14 are symmetrical .
  • the bayonet fitting 44 (FIG. 8) has a retaining flange 72, the shape of which is adjusted to pass closely through the opening 14.
  • the flange 72 is limited by edges 22 ′, 24 ′, 28 ′, 30 ′ and 32 ′ which correspond respectively to the edges 22, 24, 28, 30 and 32 of the opening 16.
  • the flange 72 is attached to the base 42 by an intermediate section 74 which appears in section in FIG. 8.
  • the section 74 is limited by two opposite edges 76 and 78 in the form of a quarter of a circle centered on the axis X′X ′ and having a smaller radius than the edges 30 ′ and 32 ′ of the flange 72.
  • the edges 76 and 78 are joined together, on one side, by a straight edge 80 coinciding in part with the edge 22 ′ and another straight edge 82 extending parallel at the edge 28 ′.
  • edges 80 and 82 are connected together by a cut edge 84.
  • the edges 76 and 78 are connected together by a straight edge 86 partly coincident with the edge 24 ′ of the flange and a straight edge 88 which extends perpendicularly to the edge 86 and which is connected with the latter by a small edge 90 in the form of an arc of a circle.
  • the end piece After introduction of the flange 72 through the opening 16, in the axial direction XX ′, the end piece is turned a quarter of a turn in the direction of the arrow F ′ to reach the locking position shown in broken lines in FIG. 7.
  • the edges 82 and 86 of the section 74 come to bear respectively against the edges 24 ′ and 22 ′ of the opening 16 which limits the rotation of the end piece.
