  • the water box 30 comprises two opposite side walls 32, 34 and two other opposite side walls 36 and 38, which are connected to a bottom wall 40.
  • the four walls 32, 34, 36 and 38 together define an open face delimited by an edge 42 of rectangular outline serving, in a manner known per se, for assembling the water box on a collector (not shown).
  • the water box 30 internally contains a secondary heat exchanger designated as a whole by 44.
  • the latter is intended to allow the cooling of a fluid different from that which circulates in the water box 30, for example the cooling of a gearbox oil.
  • the secondary heat exchanger 44 is, in the example, constituted by a stack of half-blades 46 and 48 which together constitute the body 50 of the heat exchanger 44.
  • the latter comprises two distributor tubes 52 forming a tie, the free ends are connected to two rings 54 in the form of rings, coaxial with two distributor tubes 52, each of the flanges being connected to the body 50 of the heat exchanger by means of a cylindrical part 56, also in the form of a ring, of smaller diameter than the flange 54.
  • Each of the tubes 52 in combination with the collar 54 and the associated cylindrical part 56, internally define a housing (not shown) suitable for receiving a connection tube 58 attached from the outside.
  • One of the pipes is used for the inlet of the fluid circulating in the secondary heat exchanger 44 and the other for the outlet of the same fluid.
  • Each of the pipes 58 is first introduced through a passage orifice 60 formed in the wall 32 of the water box and then in the corresponding receiving housing.
  • the wall 32 is provided, inside the water box, with two slides 62 located respectively in the region of the two orifices 60. These two slides are suitable for receiving respectively the flanges 54, forming a slide, to allow movement in translation of the secondary heat exchanger 44 along the wall 32 as far as a stop position where the two orifices 60 are aligned respectively with the two receiving housings of the secondary heat exchanger 44.
  • Each of the slides 62 comprises a wall 64 of generally rectangular shape which extends parallel to the wall 32 and which is separated from the latter by a distance slightly greater than the thickness of the collar 54 (FIG. 2).
  • Each flange has two opposite annular faces: a face 66 adapted to bear against the internal face of the wall 32 and a face 68 adapted to bear against the internal face of the wall 64.
  • the latter comprises a notch 70 limited by two substantially parallel edges 72 and 74, arranged opposite and defining the direction of translation of the slide.
  • the edges 72 and 74 are separated by a distance substantially equal to the external diameter of the cylindrical wall 56 for its guidance in the direction of translation.
  • the edges 72 and 74 are joined together by an edge 76 in a semicircle whose diameter is substantially equal to the diameter of the cylindrical part 56 and whose center is aligned with the center of the passage orifice 60 which is associated with it .
  • the notch 70 thus has an open end directed towards the side of the open face of the water box and a closed end directed towards the side of the bottom 40 of the water box. This closed end limited by the edge 76 forms a stop when the corresponding flange 56 is introduced.
  • each slide is connected to the wall 32 of the water box by two parallel connecting edges 78 and 80 separated by a sufficient distance to allow passage to the flange 54 which thus forms a slide capable of sliding in this slide .
  • this wall 64 is directly connected to the bottom wall 40 of the water box.
  • the water box is formed from a plastic material and the two slides have also been molded therewith.
