Definitions

  • the inner face is for example convex while being seen from the delimiting wall.
  • the combined device 12 has a "high pressure” inlet 13 through which the refrigerant from the gas cooler 4 is admitted inside the combined device 12.
  • the combined device 12 also has a “high pressure” outlet 14 to through which the high pressure refrigerant is discharged from the combined device 12 to the expansion member 6.
  • the "high pressure" inlet 13 and the “high pressure” outlet 14 are connected to each other by the intermediate of a “high pressure” circulation path 24 which includes the branch "high pressure" 9.
  • the combined device 12 comprises an enclosure 26 which consists of an upper partition 27, a lower partition 28 and at least one peripheral wall 29.
  • the latter is in particular formed into an elongated tube whose ends are closed by an upper cover forming the upper partition 27 and a lower cover forming the lower partition 28.
  • the enclosure 26 houses a one-piece internal component 30 which is formed of a delimiting wall 31 of the separation zone 19 and of the accumulation zone 20, of a confinement wall 32 of the internal heat exchanger 5 with respect to the accumulation zone 20, and a conduit 33 which connects the confinement wall 32 and the boundary wall 31.
  • the designers of the present invention have made the choice to assign to a single single-piece internal component 30 all or active participation in the above functions of the combined device. This choice facilitates assembly operations of said combined device 12, reduces the size and weight of the latter, said integral monoblock component 30 being easily achievable at a lower cost.
  • the integral assembly 31, 32, 33 consists of two parts assembled by interlocking, by gluing or the like and respectively constituted for example on the one hand by the delimiting wall 31 and the duct 33 which confer the one-piece character and on the other hand of the confinement wall 32, or constituted for example again on the one hand the delimiting wall 31, and on the other hand the conduit 33 and the confinement wall 32 which gives the monoblock character.
  • the boundary wall 31 partially isolates the separation zone 19 and the accumulation zone 20 from each other.
  • the boundary wall 31 is interposed between the separation zone 19 and the accumulation zone 20.
  • the conduit 33 is interposed between the boundary wall 31 and the containment wall extending inside the accumulation zone 20.
  • the conduit 33 has a first end 34 equipped with a first opening 35 which is provided through the delimiting wall 31 and a second end 36 equipped with a second opening 37 which is formed through the confinement wall 32.
  • the duct 33 delimits an internal volume 38 which is in aeraulic communication with the separation zone 19 through through the first opening 35 and with the internal heat exchanger 5 through the second opening 37.
  • the delimiting wall 31 is in the form of a disk, a center 42 of which is provided with the first opening 35 and a flange 43 of which is provided with lugs 44 for positioning the delimiting wall 31 against the peripheral wall 29 of the enclosure 26 .
  • the flat tube 21 is bordered by two secondary flat tubes 50 inside which circulates the refrigerant fluid at low pressure.
  • the flat tube 21 is bordered by a single secondary flat tube 50, indifferently internal or external.
  • the flat tube 21 is simply bathed in the low-pressure refrigerant fluid which flows inside an interstitial space formed between two consecutive turns of the winding of the flat tube 21 on it -even.
  • the upper plate 55 finally has an oblong hole 100 whose function is to allow the passage of the oil which accumulates between the face outer wall 77 of the confinement wall 32 and the upper plate 55 to direct it towards the "low pressure" outlet 16, when using the integral inner component as shown in FIGS. figures 9 or 10 .
  • said lower platen 56 consists of two elementary platens 68, 69, including an upper platinum element 68 and a platinum Lower elementary element 69. Between the upper elementary plate 68 and the lower elementary plate 69, a reserve of oil 70 is formed.
  • the lower elementary plate 69 is provided with a radial notch 71 for receiving an oil filter 72.
  • the containment wall 32 has an inner edge 74 provided with a first groove 75 for receiving said first seal 76 between the confinement wall 32 and the central ring 60 constituting the internal heat exchanger 5.
  • a channel 83 is formed between the inner face 73 and the outer face 77 of the containment wall 32.
  • Such a channel 83 which extends from the inner face 73 to the outer face 77 of the confinement wall 32 allows reintegration lubricating oil at said "low pressure" outlet 16 of the combined device 12, that is to say downstream of the internal heat exchanger 5 in a direction of circulation 11 of the refrigerant to the The interior of the air-conditioning loop 1.
  • a hole 84 is formed between the inner face 73 and an internal volume 38 of the conduit 33.
  • Such a hole 84 allows a reintegration of the lubricating oil at the inlet 23 of the branch "low pressure" 10 of the internal heat exchanger 5, that is to say upstream of the internal heat exchanger 5 in a direction of circulation 11 of the refrigerant inside the air conditioning loop 1.
