Definitions

  • the present invention is in the field of air conditioning loops cooperating with a ventilation system, heating and / or air conditioning of a motor vehicle. It relates to a combined device comprising a heat exchanger and a accumulator participating in such a loop. It also relates to an air conditioning loop comprising such a combined device.
  • a motor vehicle is commonly equipped with a ventilation, heating and / or air conditioning system to regulate the aerothermal parameters of the air contained inside the passenger compartment of the vehicle.
  • a ventilation, heating and / or air conditioning system to regulate the aerothermal parameters of the air contained inside the passenger compartment of the vehicle.
  • Such an installation cooperates with an air conditioning loop to cool a stream of air prior to the delivery of the latter inside the passenger compartment.
  • Said loop comprises a plurality of elements or components inside which circulates successively, that is to say in series, a cooling fluid, such as a supercritical fluid, carbon dioxide known under the reference R744.
  • These elements comprise at least one compressor, a gas cooler, a heat exchanger, more particularly called internal heat exchanger, an expansion member, an evaporator and an accumulator.
  • the refrigerant flows from the compressor to the gas cooler, then through a "high pressure” branch of the internal heat exchanger, then to the expansion member, then through the evaporator, and then to the accumulator, and finally through a branch "low pressure" of the internal heat exchanger, to return to the compressor.
  • the compressor is intended to receive the refrigerant fluid in the gaseous state and to compress it to carry it at high pressure.
  • the gas cooler is able to cool the compressed refrigerant at a relatively constant pressure, giving up heat to its environment.
  • the expansion member is able to lower the pressure of the refrigerant leaving the gas cooler by bringing it at least partly in the liquid state.
  • the evaporator is itself able to bring the refrigerant fluid arriving in the liquid state coming from the expansion element, at a relatively constant pressure, into the gaseous state, by taking heat from a flow of air which crosses the evaporator. The vaporized refrigerant is then sucked by the compressor.
  • the air conditioning loop includes a "high pressure" line that starts at the outlet of the compressor and ends at the inlet of the expansion member, according to a direction of circulation of the refrigerant fluid inside the air conditioning loop, the cooler of gas and the branch "high pressure" of the heat exchanger being interposed between these two points.
  • the air conditioning loop also comprises a "low pressure" line which starts at the outlet of the expansion device and ends at the inlet of the compressor, according to the direction of circulation of the refrigerant inside the air conditioning loop, the evaporator, the accumulator and the branch "low pressure" of the heat exchanger being interposed between these two points.
  • the accumulator provides a separation function between a gaseous phase and a liquid phase of the refrigerant.
  • the accumulator comprises a separation zone dedicated to this function.
  • the accumulator also provides a storage function for a circulating coolant charge depending on the conditions of use of the air conditioning loop.
  • the accumulator comprises a refrigerant storage zone in the liquid state that said accumulator collects from the evaporator.
  • the accumulator consists of an enclosure housing the separation zone and the accumulation zone, the enclosure comprising a bottom wall which delimits the accumulation zone in the lower part of the enclosure.
  • the heat exchanger is called internal heat exchanger or internal heat exchanger in that it is configured so that the refrigerant circulating inside the branch "high pressure” can yield heat to the circulating refrigerant inside the "low pressure” branch. It is therefore understood that the exchange is between the same fluid circulating at different locations of the air conditioning loop, without exchanging with air for example.
  • the document JP 10019421 proposes to associate the internal heat exchanger and the accumulator in a combined device.
  • the latter comprises said enclosure which is provided with an opening.
  • the chamber houses the internal heat exchanger which overhangs the refrigerant storage zone in the liquid state, the heat exchanger being interposed between the separation zone and the accumulation zone, in the use position. of the combined device on the air conditioning loop.
  • the high pressure refrigerant fluid from the gas cooler enters the interior of the combi device through a "high pressure” inlet through the enclosure to circulate within the heat exchanger internal and finally be discharged out of the combined device via a "high pressure” outlet also provided through the enclosure.
  • the refrigerant fluid at low pressure from the evaporator enters the interior of the combined device through a "low pressure" input still formed through the enclosure.
  • the refrigerant fluid at low pressure and in the liquid state tends to accumulate by gravity above the lower wall of the enclosure while the refrigerant fluid at low pressure and in the gaseous state tends to concentrate in an upper zone of the enclosure.
  • the latter houses a bent duct arranged in a U, a first end of which is disposed in the upper part of the enclosure to admit the refrigerant fluid at low pressure and in the gaseous state into the duct, and convey it to a second end of the conduit in communication with the internal heat exchanger. Inside the latter, the high-pressure refrigerant yields heat to the refrigerant at low pressure.
  • the refrigerant fluid at low pressure and in the gaseous state is discharged out of the internal heat exchanger and out of the combined device through a "low pressure" outlet also formed through a wall of the enclosure.
  • the object of the present invention is therefore to solve the disadvantages described above mainly by cleverly arranging the heat exchanger in the chamber of the accumulator. To do this, the heat exchanger is offset relative to the enclosure so as to minimize the outer dimensions of the combined device. This arrangement makes it possible to create a lateral evacuation chamber at the exchanger without having to either increase the diameter of the enclosure or to lengthen the enclosure to create an evacuation chamber under the heat exchanger.
  • the subject of the invention is therefore a combined device comprising an enclosure housing at least one heat exchanger and an accumulation zone, said enclosure extends along a primary central axis and said heat exchanger extends along a secondary central axis, characterized in that the primary central axis is offset with respect to the secondary central axis.
  • the offset between the primary central axis and the secondary central axis is between one and twenty-five millimeters.
  • the enclosure and the heat exchanger are of cylindrical shape.
  • the heat exchanger comprises at least a first flat tube wound on itself around the secondary central axis.
  • the first flat tube comprises a plurality of channels.
  • the heat exchanger comprises an intake chamber which extends in the center of the first flat tube wound on itself.
  • the combined device comprises an evacuation chamber located at least partially around the heat exchanger, this evacuation chamber being delimited by an outer wall of the heat exchanger and by an inner wall of the enclosure.
  • the heat exchanger comprises a first circulation path delimited by the multiplicity of channels of the first flat tube, this first circulation path being in communication via a first end of the flat tube with the admission chamber and in communication with the evacuation chamber via a second end of the first flat tube.
  • the first circulation path is delimited by a second flat tube wound with the first flat tube.
  • the heat exchanger comprises a second circulation path delimited by a plurality of channels of a third flat tube wound with the first flat tube.
  • the second circulation path is, on the one hand, in communication with a first pipe placed on the periphery of the heat exchanger and, on the other hand, in communication with a second pipe of which the axis is aligned with the secondary central axis.
  • first flat tube and the second flat tube, the third flat tube, the first pipe and the second pipe form a unitary unit.
  • the enclosure is closed by an upper partition and a lower partition and the accumulation zone comprises a bottom wall disposed at the boundary between the heat exchanger and said accumulation zone.
  • the device according to the invention comprises a first conduit which passes through the upper partition and opens into a separation zone located in the chamber and above the accumulation zone.
  • the combined device comprises a second conduit which passes through the lower partition and opens into the evacuation chamber.
  • the invention also relates to an air conditioning loop in which is incorporated a combined device incorporating at least one of the features described above.
  • a first advantage of the invention lies in the fact that it is possible to keep a component of small external dimensions without increasing the internal pressure losses, in particular on the first flow path. This makes it easier to integrate the component according to the invention into an engine compartment where space is increasingly reduced.
  • the figure 1 illustrates a combined device 1 according to the invention comprising an enclosure 2 closed by an upper partition 3, otherwise called upper cover, and a lower partition 4, or lower cover.
  • the enclosure 2 extends along a primary central axis A in a longitudinal direction.
  • the chamber 2 has a section of cylindrical shape but it can also be parallelepipedal shape (square, rectangular, ).
  • the length of the chamber 2 measured in the direction of the primary central axis A is greater than the outside diameter measured perpendicular to the primary central axis A.
  • the combined device 1 also comprises a "high pressure" inlet 5 through which a refrigerant fluid 16 from a gas cooler is admitted inside the combined device 1.
  • This "high pressure” inlet 5 is materialized by a first pipe 12 of tubular shape which passes through the lower partition 4 to connect to a heat exchanger 9.
  • the combined device 1 further comprises a "high pressure” outlet 6 through which the high pressure refrigerant is discharged from the device combined 1 towards the relaxing organ.
  • This "high pressure” outlet 6 takes the form of a second tubular pipe 13, which starts at the heat exchanger 9 to pass through the internal volume of the chamber 2 and open through the upper wall 3.
  • the combined device 1 also comprises a "low pressure" inlet 7 through which the refrigerant fluid from the evaporator is admitted inside the combined device 1.
  • the "low pressure” inlet 7 takes the form of a “low pressure” inlet 7.
  • first pipe 14 which passes through the upper wall 3.
  • the combined device 1 finally has a “low pressure” outlet 8 through which the fluid Low pressure refrigerant is discharged from the combined device 1 to the compressor.
  • This "low pressure” outlet 8 here also takes the form of a second pipe 15 of tubular shape which passes through the lower partition 4.
  • the combined device 1 comprises the enclosure 2, sealed from the outside, which houses the heat exchanger 9, a separation zone 10 between the gas phase 16a and the liquid phase 16b of the refrigerant leaving the the evaporator and an accumulation zone 11 of the refrigerant fluid in the liquid state from the evaporator, or more particularly from the separation zone 10.
  • Said separation zone 10 preferably has a cyclonic structure in the sense that the first pipe 14 is offset relative to the primary central axis A of the enclosure 2 of the combined device 1 to allow a tangential admission of the refrigerant fluid from the The tangential inlet is put into practice by means of a lumen 17 made through the cylindrical wall of the first pipe 14. These provisions are intended to promote the separation between them.
  • One end of the first pipe 14 located inside the internal volume of the chamber 2 is closed by a plate 18. The latter extends perpendicular to the primary central axis A of the chamber 2. A weak game is maintained between the periphery of this plate 18 and the inner wall 19 of the chamber 2 so as to allow the descent by gravity of the liquid phase 16b of the refrigerant 16 to the accumulation zone 11.
  • the accumulation zone 11 is delimited by a bottom wall 20 against which the coolant in the liquid state from the evaporator accumulates by gravity.
  • the "low pressure" inlet 7 being, in the position of use of the combined device 1 on the air-conditioning loop and / or in the operating position of the combined device 1 alone, placed above the lower wall 20, the fluid refrigerant 16 in the liquid state falls naturally by gravity from the entry "low pressure" 7 to the bottom wall 20 to finally rest against it.
  • the bottom wall 20 is sealed against the inner wall 19 of the enclosure 2.
  • the accumulation zone 11 is crossed by the second pipe 13 but is also crossed by an intermediate pipe 21, a first end 21a opens into the separation zone 10, a few millimeters above a plane defined by the plate 18.
  • This arrangement makes it possible to ensure that the liquid phase 16b of the cooling fluid does not enter the intermediate pipe 21 so as to let in only the gas phase 16a of the refrigerating fluid 16.
  • the intermediate pipe 21 passes through the bottom wall 20 and has a second end 21b which is in communication with the heat exchanger 9.
  • the intermediate pipe 21 is of a larger diameter than the second pipe 6 and is mounted coaxially with respect to the latter.
  • both the axis of the intermediate duct 21 and the axis of the second duct 6 are offset with respect to the primary central axis A of the enclosure 2.
  • the intermediate pipe 21 is always of a larger diameter than the second pipe 6.
  • the central axis of the intermediate pipe 21 is coincidental or coaxial with the primary central axis A. It is therefore clear that the intermediate pipe is in the center of the cylinder formed by the enclosure 2. In this configuration, however, the heat exchanger 9 is always shifted as required by the invention.
  • the second pipe 6 is shifted in the intermediate pipe 21, in other words the central axis of the second pipe 6 is not coaxial or coincides with the central axis of the intermediate pipe 21, the latter being confused with the primary central axis A.

  • the heat exchanger 9 consists of a first flat tube 22 wound on itself, preferably around a secondary central axis B of the heat exchanger, this secondary central axis B being distinct, that is to say non-coaxial, of the primary central axis A of the chamber 2 of the combined device 1. It will be noted that this offset d, formed by the distance between the primary central axis A of the secondary central axis B , allows to release an area of the lower partition 4 in which it is then easier to unclog the second pipe 15 without increasing the external dimensions of the chamber 2, and therefore the combined device as a whole. Note that the primary central axis A and the secondary central axis B are parallel.
  • the first flat tube 22 houses a multiplicity of channels 23, otherwise called micro-channels, for the passage of refrigerant fluid at low pressure.
  • This multiplicity of channels 23 materializes a first flow path of the refrigerant fluid at low pressure.

  • the first circulation path comprises a second flat tube 26 provided with a plurality of channels 23.
  • This second flat tube 26 is wound with the first flat tube 22 and together forms the first flow path of the refrigerant fluid 16 at "low pressure" .
  • the heat exchanger 9 further comprises a third flat tube 27 whose multiple channels 23 defines a second circulation path, the latter being borrowed by the refrigerant fluid "high pressure".
  • This third flat tube 27 is on one side in communication with the first pipe 12 placed at the periphery of the heat exchanger and the other, in communication with the second pipe 13 whose axis is aligned or coincident with the secondary central axis B of the heat exchanger 9.
