Definitions

  • the present invention relates to the domain of heat exchangers designed for refrigerant fluid loops. More specifically, the present invention concerns devices for filtering the refrigerant fluid that flows through such heat exchangers.
  • a refrigerant fluid loop generally comprises at least two heat exchangers, at least one compressor and at least one expansion device.
  • the compressor and the expansion device are both fragile and comprise movable elements that can easily break. It is therefore important that only the refrigerant fluid enters this compressor or the expansion device. In order to achieve that goal, it is already known to filter the refrigerant fluid before it reaches one of these components.
  • the present invention solves at least this issue, by providing a heat exchanger for a refrigerant fluid loop, the heat exchanger comprising at least one inlet configured to allow a refrigerant fluid to enter in the heat exchanger and at least one outlet configured to allow the refrigerant fluid to exit the heat exchanger, the heat exchanger comprising at least one manifold arranged at an end of a heat exchange area of the heat exchanger, at least the outlet being arranged in the at least one manifold, the manifold extending mainly along a first axis between a first end and a second end.
  • the heat exchanger comprises at least one filtering baffle adapted to filter at least part of the refrigerant fluid, the filtering baffle is arranged in the manifold of the heat exchanger and the filtering baffle is arranged closer to the outlet than to the first end or the second end of the manifold.
  • the filtering baffle is arranged in the vicinity of the outlet.
  • the heat exchange area is a part of the heat exchanger wherein a heat exchange occurs, for instance between the refrigerant fluid and an airflow that flows through such heat exchange area or between the refrigerant fluid and another fluid flowing through another loop, the heat exchanger of the invention being then arranged at an interface between the two loops.
  • the filtering baffle is arranged upstream the outlet of the heat exchanger with respect to a direction along which the refrigerant fluid flows.
  • the filtering baffle is arranged in the manifold of the heat exchanger, the filtering baffle is thus arranged between the heat exchange area and the outlet.
  • the filtering baffle is closer the filtering baffle is to the outlet, the more of the refrigerant fluid is filtered.
  • the filtering baffle comprises at least one frame and one meshed element, the frame surrounding, at least partially, the meshed element.
  • a first part of the meshed element is configured to filter the refrigerant fluid and a second part of the meshed element is configured to cooperate with the frame.
  • the frame and the meshed element both comprise a metal alloy.
  • the filtering baffle can thus be brazed to the wall defining the manifold. The brazing operation prevents any refrigerant fluid leakage, that is to say that the refrigerant fluid that reaches the filtering baffle is either filtered through the meshed element, and more precisely through the first part of such meshed element, or guided to the heat exchange area.
  • the heat exchanger according to the invention can comprise at least two filtering baffles.
  • the two filtering baffles are arranged on both sides of the outlet along the first axis. It is thus understood that the refrigerant fluid that reaches the manifold between the two filtering baffles is not filtered before exiting the heat exchanger.
  • the refrigerant fluid that is not filtered represents only a small part of the total amount of the refrigerant fluid that exits the heat exchanger. In other words, the majority of the refrigerant fluid that exits the heat exchanger has been previously filtered.
  • a distance measured between the two filtering baffles along the first axis must be as short as possible in order to improve the efficiency of the filtration.
  • the frame extends mainly along the first axis along which extends the manifold, this frame carrying the meshed element, and the frame comprising at least one baffle arranged at one extremity of the frame along the first axis, said baffle extending mainly along a second axis that intersects the first axis.
  • the second axis is perpendicular to the first axis.
  • at least the frame comprises a metal alloy and said frame is brazed to the wall defining the manifold.
  • the brazing operation prevents any refrigerant fluid leakage, that is to say that the refrigerant fluid that reaches the at least one baffle is either filtered through the meshed element, and more precisely through the first part of such meshed element, or guided to the heat exchange area.
  • the first part of the meshed element fits the outlet of the heat exchanger and the at least one baffle is adapted to guide the refrigerant fluid to the heat exchange area of the heat exchanger.
  • the first part of the meshed element fits the outlet of the heat exchanger and the at least one baffle comprises another meshed element adapted to filter the refrigerant fluid.
  • the first part of the meshed element fits the outlet of the heat exchanger and the at least one baffle is perforated in order to define an opening configured to allow the circulation of the refrigerant fluid.
  • the first part of the meshed element fits the outlet means that said first part of the meshed element presents similar shape and dimension than the shape and dimension of the outlet.
  • a first baffle is arranged at a first extremity of the frame and a second baffle is arranged at a second extremity of the frame, the first extremity and the second extremity being opposed to one another along the first axis, the first baffle extending along the second axis and the second baffle extending along a third axis that intersects the first axis.
  • the second and the third axis can be parallel to each other.
  • those second and third axis can be perpendicular to the first axis.
  • both baffles are configured to guide the refrigerant fluid to the heat exchange area of the heat exchanger.
  • both baffles comprise the other meshed element adapted to filter the refrigerant fluid.
  • both baffles are perforated in order to allow the circulation of the refrigerant fluid.
  • the meshed element is configured to filter particles that present a diameter bigger than 30 ⁇ m. More precisely, at least the first part of this meshed element is configured to retain particles that presents a diameter bigger than 30 ⁇ m.
  • the heat exchanger can be used as a condenser.
  • the heat exchanger is a tubular heat exchanger.
  • the heat exchange area of such heat exchanger comprises tubes adapted to the circulation of the refrigerant fluid.
  • the heat exchanger can comprise stacked plates which define those tubes.
  • upstream and downstream both refer to a direction of circulation of a refrigerant fluid in the concerned object.
  • FIG 1 is a schematic view of a refrigerant fluid loop 100 intended to be accommodated in a motor vehicle.
  • This refrigerant fluid loop 100 comprises at least a compressor 110 configured to increase the pressure of a refrigerant fluid R circulating through the loop 100, a first heat exchanger 120 configured to undertake a heat exchange between the refrigerant fluid R and a first airflow AF1, an expansion device 130 configured to decrease the pressure of the refrigerant fluid R and a second heat exchanger 140 configured to undertake a heat exchange between the refrigerant fluid R and a second airflow AF2.
  • the first airflow AF1 is taken outside the motor vehicle in which the refrigerant fluid loop 100 is accommodated
  • the second airflow AF2 is reserved to be sent in a passenger compartment of said motor vehicle.
  • the first heat exchanger 120 is realized according to the invention and comprises at least one filtering baffle 200 located in the vicinity of an outlet 122 of the first heat exchanger 120.
  • the refrigerant fluid R exits the compressor 110 in a gaseous state and reaches the first heat exchanger 120, and more precisely it reaches an inlet 121 of the first heat exchanger 120.
  • a transfer of calories is undertaken between said refrigerant fluid R circulating in this first heat exchanger 120 and the first airflow AF1 that flows through it. More precisely, the refrigerant fluid R gives calories to the first airflow AF1 and liquefies.
  • the first heat exchanger 120 acts, in this particular example, as a condenser.
  • the refrigerant fluid R exits the first heat exchanger 120 in a liquefied state and reaches a pipe 101 of the refrigerant fluid loop 100. Then the refrigerant fluid R goes through the expansion device 130 in which its pressure is reduced before it reaches the second heat exchanger 140. In this second heat exchanger 140, the refrigerant fluid R takes calories from the second airflow AF2 and evaporates. The second airflow AF2 can then be sent to the passenger compartment to drop the temperature of this compartment and the refrigerant fluid R, which is again in a gaseous state, can again reach the compressor 110 to start a new cycle.
  • the first heat exchanger 120 and the second heat exchanger 140 are similar and both comprise at least two manifolds or header tanks arranged at one end or at both ends of a heat exchange area wherein the heat exchange between the refrigerant fluid and the first or the second airflow AF1, AF2 takes place.
  • the outlet 122 of the first heat exchanger 120 is arranged in one of its manifolds, and the inlet 121 of this first heat exchanger 120 is arranged in the other one.
  • the at least one filtering baffle 200 is arranged in the manifold in which is arranged the outlet 122 of the first heat exchanger 120. In other words, said filtering baffle 200 is arranged upstream the outlet 122 of the first heat exchanger 120 and downstream the heat exchange area.
  • the filtering baffle 200 is adapted to filter the refrigerant fluid that has already exchanged heat with the first airflow AF1, and before it reaches the rest of the refrigerant fluid loop 100. As a result, the refrigerant fluid R that reaches the expansion device 130 is cleared of the biggest particles that can be dragged along its flows through the heat exchange area.
  • the filtering baffle 200 can be configured to retain particles that present a diameter bigger than 30 ⁇ m.
  • the heat exchange area comprises tubes adapted to the circulation of the refrigerant fluid R.
  • each of those tubes comprise a first end which extends in the manifold in which the outlet 122 is arranged and a second end which extends in the manifold in which the inlet 121 is arranged.
  • those tubes can be formed by stacked plates.
  • Figures 2 and 3 illustrate, in perspective views, the manifold 123 of the heat exchanger in which the outlet 122 is arranged according, respectively, to a first embodiment and to a second embodiment of the invention.
  • the word "manifold” is, in the rest of the specification used to designate the manifold of the heat exchanger in which is arranged the outlet of such heat exchanger.
  • the manifold 123 extends mainly along a first axis A1.
  • This manifold 123 also comprises a first end and a second end opposed to each other along the first axis A1, those first and second ends being hidden on the figures.

  • the at least one filtering baffle 200 is arranged in order to filter, at least part of, the refrigerant fluid before it exits the heat exchanger 120.
  • the filtering baffle 200 is arranged upstream the outlet 122, according to both the first and the second embodiments.
  • a block 300 is connected to the outlet 122, and more precisely downstream the outlet 122.
  • the refrigerant fluid that exits the heat exchanger through its outlet 122 reaches such block 300 before reaching the rest of the refrigerant fluid loop as explained above.
  • the heat exchanger comprises two filtering baffles 200.

According to the first embodiment of the invention, both the filtering baffles 200 are identical and the description given under about one of them is directly transposable to the other one.
  • each filtering baffle 200 is arranged between two immediately adjacent tubes 124 of the heat exchange area 125. More precisely, each filtering baffle 200 is arranged between the first ends 127 of such tubes 124.
  • the filtering baffles 200 are arranged on both sides of the outlet 122, along the first axis A1. As a result, the refrigerant fluid that reaches the manifold 123 by the tubes 124 arranged in front of the outlet 122 is not filtered before it exits the heat exchanger. It is understood that the refrigerant fluid that exits the heat exchanger without previous filtration only represents a very small amount of the refrigerant fluid that exits said heat exchanger.
  • the refrigerant fluid that reaches the manifold anywhere else than between the two filtering baffles 200 is either filtered by one of them, or guided again to the heat exchange area.

  • the meshed element 203 completely covers the outlet 122. As a result, all the refrigerant fluid that exits the heat exchanger 120 is previously filtered.
