Definitions
- the present invention concerns the domain of heat exchangers designed for refrigerant fluid loops. More specifically, the present invention relates to 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.
- JPH06129733A discloses a heat exchanger according to the preamble of claim 1.
- the present invention solves at least this issue, by providing a heat exchanger according to claim 1.
- Such filter is located at the outlet where a pipe of the refrigerant fluid loop is attached to heat exchanger.
- the heat exchanger comprises an integrated receiver dryer, the filter is separated from any filtering means that could be located in the integrated receiver dryer, and is located downstream this integrated receiver dryer.
- the filter is configured to filter particles presenting a certain diameter, for example above 30 ⁇ m, preferably above 50 ⁇ m, that can be dragged by the refrigerant fluid along its flow through the heat exchanger. As a result, those particles are prevented to reach any other element of the refrigerant fluid loop.
- the heat exchanger comprises a block arranged at the outlet of the heat exchanger, the block comprising a path configured to allow a circulation of the refrigerant fluid inside the block, such path extending between the outlet of the heat exchanger and an orifice of the block, such orifice being configured to allow the refrigerant fluid to exit the block, wherein the block is provided with at least one opening configured to allow the insertion of the filter inside the block.
- the block can be welded or brazed to the heat exchanger, especially to the header tank.
- the path arranged inside the block directly extends the outlet of the heat exchanger in order to make sure that all the refrigerant fluid that exits the heat exchanger reaches the path of the block.
- Arranging the filter at the outlet of the heat exchanger allows a filtration of the particles that can remain in it, for instance due to manufacturing process, that are otherwise complex to clean. As the filter is pushed into the block through the opening, it can easily be removed and changed or cleaned, when needed.
- the block comprises a cap configured to close the opening.
- the cap comprises a first portion configured to secure the cap to the block and a second portion configured to close the opening through which the filter is inserted in the block.
- the shape and the dimensions of the second part are similar, or substantially similar, to the shape and the dimensions of the opening.
- the first portion of the cap can be screwed to the block.
- the filter extends, at least partially, in the path arranged in the block.
- This filter is arranged in such a way that the refrigerant fluid enters the filter flowing along a first direction and exits the filter along a second direction, the first direction intersecting the second direction.
- the first direction and the second direction are perpendicular.
- the path comprises at least a first part, a second part substantially parallel to the first part, and a third part connecting the first part with the second part, the third part intersecting the first part and the second part.
- the third part extends perpendicularly to the first part and the second part.
- the path can comprise a fourth part connected to the second part, this fourth part intersecting the second part.
- the fourth part can extend perpendicularly to the second part.
- the second part, the third part and the fourth part form a U-shape wherein the base is formed by the third part and wherein the branches are respectively formed by the second and the fourth parts.
- the filter is arranged at a junction between the second part and the third part.
- the filter can extend mainly parallel to the second part.
- the filter can, according to this first embodiment, extend mainly parallel to the third part.
- the filter is arranged at a junction between the second part and the fourth part, and the filter extends mainly parallel to the fourth part.
- the opening through which the filter is inserted in the block is arranged on different part of this block. In any case, this opening is arranged on order for the filter to be pushed into the path arranged in the block.
- the filter comprises a frame in which at least one aperture is realized, the aperture being closed by a meshed element.
- this meshed element can be made of synthetic material.
- the meshed element can be made of metal.
- the size of this meshed element determines the size of the particles that are retained by the filter and according to the invention, this meshed element is configured to retain particles presenting a certain diameter, for example larger than 50 ⁇ m.
- the filter can have a cylindrical shape with a circular cross section.
- the filter extends mainly along a longitudinal axis, the filter comprising a first end and a second end along this longitudinal axis, and the filter comprises a collar arranged at its first end, this collar being configured to seal the opening through which the filter can be inserted in the block. More precisely, this collar is arranged between the block and the cap, and especially between the block and the second portion of the cap. For example, the collar can be overmolded on the first end of the filter. As a result, it is to be understood that the filter is inserted in the path arranged in the block by its second end.
- a sealing device is arranged between the second end of the filter and a wall defining the path. More precisely, the sealing device is arranged between an outer periphery of the filter and the wall defining the path arranged in the block. In other words, this sealing device is designed to be in contact both with the wall defining the path and with the outer periphery of the filter.
- the filter comprises both the collar and the sealing device, it is understood that all the refrigerant fluid that flows through the path of the block also flows through the filter.
- the sealing device can be an O-ring.
- the sealing device can comprise at least one tooth realized on an outer periphery of the frame of the filter.
- the at least one tooth and the outer periphery of this frame form a single piece, that is to say that the outer periphery of the frame and the at least one tooth cannot be separated without damaging one of them.
- the sealing device comprises three teeth, all of those teeth extending all around the outer periphery of the frame of the filter and the wall defining the path.
- the block is made of a single piece.
- the block forms a monobloc piece and the elements that are part of it cannot be separated without damaging at least one of them.
- a monobloc piece may be attached to the header tank of the heat exchanger, for example by welding or brazing.
- a duct can be layered between the outlet and the block.
- the connection between the block and the outlet of the heat exchanger can be indirect, allowing the block to be placed away from the heat exchanger, without reducing the efficiency of the filtration.
- the present invention also concerns a refrigerant fluid loop comprising at least one compressor, a first heat exchanger, one expansion device, and a second heat exchanger, wherein at least the first heat exchanger is realized according to the present invention.
- the present invention also relates to a motor vehicle comprising at least one refrigerant fluid loop comprising at least one heat exchanger according to the present invention.
- the heat exchanger can be used as a condenser, that is to say that this heat exchanger is configured to allow the refrigerant fluid that flows through it to cool and, as a result, to liquefy.
- 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 a block 200 in which, as explain in more details below, a filter 300 is arranged.

- 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 the block 200 wherein it is filtered by the filter 300.
- the block 200 is connected on one hand to an outlet 122 of the first heat exchanger 120 configured to allow the refrigerant fluid R to exit said first heat exchanger 120 and on the other hand to a pipe 101 of the refrigerant fluid loop 100.
- the refrigerant fluid R goes through the expansion device 130 in which its pressure is reduced before it reaches the 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.
- first heat exchanger 120 and the second heat exchanger 140 are similar and both comprise at least two manifolds or header tanks arranged at an extremity of a heat exchange area wherein the heat exchange between the refrigerant fluid and the first or the second airflow AF1, AF2 takes place.

- this connection prevents any refrigerant fluid leakage between the heat exchanger and the block 200.
- a duct can be layered between the block and the heat exchanger, this duct being at least long enough to avoid any physical contact between the heat exchanger and the block.
- the block is arranged away from the heat exchanger, but is in anyway considered as the outlet of the heat exchanger, because this block is a one-component with the rest of the heat exchanger, and is the part that received the pipe connecting the heat exchanger to the refrigerant fluid loop.
- the block 200 also comprises a path that extends between the inlet of the block 200 and an orifice 221 of the block 200 - that can be seen on figures 4 to 6 - which allows the refrigerant fluid to exit the block 200.
- a filter is arranged in the block 200.

- the first portion 231 is secured to the block 200 thanks to a screw 233.
- the second portion 232 is more particularly provided with a recess 234 that fits the opening 220, that is to say that said recess 234 has a similar shape and similar dimensions with the opening, in order to help preventing refrigerant fluid leakages.
- a bottom 235 that defines said recess 234 at least partially extends in the path 240 of the block 200.
- FIG 3 is a perspective view of the filter 300 that is inserted through the at least one opening arranged in the block. As illustrated, this filter 300 extends mainly along a longitudinal axis X and comprises a first end 301 and a second end 302 along this longitudinal axis X.
- This filter 300 comprises a frame 303 in which at least one aperture 304 is made, advantageously several apertures 304, those apertures 304 being closed with a meshed element 305.
- the size of this meshed element 305 determines the size of the particles that are filtered by this filter 300.
- this meshed element 305 is chosen for its ability to filter particles presenting a certain diameter, for example larger than 50 ⁇ m.
- This meshed element 305 can comprise a synthetic material or metal material.
- the filter 300 has a cylindrical shape and a circular cross section. More precisely, the frame 303 of this filter 300 has a cylindrical shape in which apertures 304 are created, each aperture 304 extending mainly parallel to the longitudinal axis X.
- the refrigerant fluid that reaches such filter 300 enters this filter 300 along a first direction d1 and exits this filter 300 along a second direction d2, the first direction d1 intersecting the second direction d2.

- this collar 310 is arranged at the first end 301 of the filter 300, and more particularly, this collar 310 can be overmolded with this first end 301. Therefore, this filter 300 is inserted in the block by its second end 302.
- the invention aims to filter all the refrigerant fluid that exits the heat exchanger.
- a sealing device 320 can therefore be arranged at the second end 302 of the filter 300. As shown on figures 3 to 6 , this sealing device 320 is layered between the filter 300 and a wall defining the path in which the filter 300 is intended to be inserted.
- This sealing device 320 can be part of the filter 300, by being moulded out of the frame 303, as shown on figure 3 or 4 .

- those teeth 321 are designed to prevent the refrigerant fluid to by-pass the filter 300, that is to say to make sure that all the refrigerant fluid that enters the block goes through the filter 300.
- this embodiment is only an example of what can be the sealing device 320, and does not restrict the present invention.
- said sealing device 320 could comprise only one tooth or more than three teeth without getting out of the invention context.
- this sealing device can be an O-ring arranged all around the second end 302 of the filter 300.
- FIG. 4 and 5 both illustrate a first embodiment of the present invention according to two different variants and figure 6 illustrates a second embodiment of the present invention. Those embodiments differ essentially from one another in the position of the filter 300 within the path 240.
- the block 200 comprises the path 240 that is reached by the refrigerant fluid that exit the heat exchanger tank and in which the filter 300 is arranged.
- the path 240 is defined by a continuous wall of the block 200 and comprises at least a first part 241 parallel to a second part 242, this first part 241 and this second part 242 being connected to each other by a third part 243 that intersects both the first and the second parts 241, 242.
- the third part 243 more precisely extends perpendicularly to the first part 241 and the second part 242.

More particularly, the first part 241 of the path 240 is arranged in the conduit 211 designed to be connected to the exit of the header tank of the heat exchanger. In other words, the first segment 341 of the wall defining the path 240 also defines the conduit 211 thanks to which the block 200 is connected to the heat exchanger.
- the opening 220 is drilled in the second segment 342 of the wall defining the path 240, and more specifically in a portion of said second segment 342 that faces the third part 243 of the path 240.

- the first direction d1 along which the refrigerant fluid enters the filter 300 is parallel to the longitudinal axis X and the second direction d2 along which the refrigerant fluid exits the filter 300 is perpendicular to this longitudinal axis X.
- the refrigerant fluid exits the filter 300 through the meshed element that closes the apertures 304 of it, that is to say that this refrigerant fluid is filtered when it exits said filter 300.
- the refrigerant fluid reaches the fourth part 244 and then exits the block 200 thanks to the orifice 221 and then continues the refrigerant fluid loop on which the block 200 is positioned.
- the block 200 differs from first embodiment illustrated on figure 4 essentially on the position of the opening 220.
- this opening 220 is realized in the third segment 343 of the wall that defines the third part 243 of the path 240 and specifically in a portion of this third segment 343 that faces the second part 242 of the path 240.
- the filter 300 inserted through said opening 220 still extends at the junction between the second and the third part 242, 243 but it extends mainly parallel to the second part 242.
- the refrigerant fluid enters by the apertures 304 closed by the meshed element 305.
- the first direction d1 is perpendicular to the longitudinal axis X and the second direction d2 is parallel to this longitudinal axis X and the refrigerant fluid is filtered when it enters the filter 300.
- the sealing device 320 also differs from the first embodiment illustrated on figure 4 and comprises an O-ring 322 arranged between the frame 303 of the filter 300 and the second segment 342 of the wall defining the path 240 and more particularly, this O-ring 322 is compressed between this second segment 342 of the wall and the frame 303 of the filter 300, in order to make sure that all the refrigerant fluid that enters the block 200 also goes through the filter 300 and that all the particles presenting a certain diameter, for example above 30 ⁇ m, preferably above 50 ⁇ m, are eliminated from this refrigerant fluid.
- Figure 6 finally illustrates a second embodiment of the present invention that differs from the first embodiment in the fact that the filter 300 is arranged at a junction between the second part 242 and the fourth part 244 and that it extends mainly parallel to said fourth part 244.
- the opening 220, through which the filter 300 is inserted is realized in a portion of the second segment 342 of the wall defining the path 240 that faces the fourth part 244 of the path 240.
- the refrigerant fluid according to this second embodiment, is filtered when it enters the filter 300.
- the refrigerant fluid enters said filter 300 through the apertures 304 when crossing the meshed element 305, that is to say that the first direction d1 extends perpendicularly to the longitudinal axis X and exits the filter 300 through its second end 302, that is to say that the second direction d2 extends parallel to the longitudinal axis X.
- the sealing device 320 is an O-ring as detailed above with reference to figure 5 .
