Definitions
- the invention relates to a heat exchanger comprising at least one manifold, the internal volume of which is defined by at least one longitudinal bore formed in an elongated solid body, and is in fluid communication with a row of tubes mutually aligned in the axial direction. or bore (s), elongated parallel to each other in a first direction substantially perpendicular to said axial direction and having a cross section elongated in a second direction substantially perpendicular to the axial direction and substantially perpendicular to said first direction.
- Such heat exchangers are used in particular for the extraction of heat from a refrigerant fluid in a motor vehicle air conditioning installation, and more particularly when the refrigerant fluid is one which, like C0 2 , must be subjected to pressures very high, for example several hundred bars.
- the manifolds used in conventional air conditioning condensers comprising, a tubular wall formed by one or more rolled sheets, would not, in fact, withstand such pressures, and a solid part is required to provide a sufficient wall thickness.
- the ends of the tubes open directly into a bore defining the interior volume of the manifold, as they do inside the sheet metal tubular wall of conventional manifolds, the high wall thickness of the manifold adds to the size of the tubes in the second direction, thereby increasing the overall size of the heat exchanger.
- the object of the invention is to remedy this drawback, and to reduce the size of the heat exchanger in the second direction, for a given length of the cross section of the tubes.
- the invention relates in particular to a heat exchanger of the kind defined in the introduction, and provides that only part of the length of the cross section of the tubes projects, in said first direction, into said interior volume, the tightness of the communication of fluid between the tubes and the interior volume being obtained by means of a cradle in the form of a profiled strip, receiving said body and brazed thereto and at the periphery of the tubes.
- At least one end of the length of the cross section of the tubes projects, in said first direction, beyond the bore or all of the bores in the second direction.
- each tube engages in a slot in said body, elongated in the second direction, opening at its two ends and the bottom of which is interrupted by said interior volume, said cradle being applied to the body so as to cover said slots and having opposite them elongated openings for the sealed passage of the tubes.
- Each slot has two lateral zones of reduced depth, the bottom of which serves as a stop for the end of the tube and a deeper central zone defining a free space which communicates with the interior of the tube.
- One end of each tube engages in a fluid-tight manner in a deep-drawn cradle of the cradle, the bottom of which is itself sealed in a transverse notch in the body and traversed by at least one opening for the communication of fluid between the tube and said interior volume.
- the body and the cradle have means of mutual mechanical attachment.
- attachment means comprise two recesses extending in the axial direction on the outer surface of the body, respectively on either side of a plane passing through the axes of the tubes, and cooperating with teeth of the cradle.
- Each tooth is formed at the free end of a tab extending substantially in a radial plane, each tab being interposed in the axial direction between two cups.
- the manifold comprises at least one transverse partition delimiting in the axial direction at least one chamber which is part of said interior volume, engaged in an opening of the body which is covered by the cradle.
- the manifold comprises at least one transverse partition delimiting in the axial direction at least one chamber which is part of said interior volume, engaged in an opening of the body beyond which it projects and carrying mechanical fastening means on the periphery of the body.
- Figure 1 is a partial exploded perspective view of a heat exchanger for extracting heat at from C0 2 in the supercritical state under high pressure, used as a refrigerant in an air conditioning circuit of a motor vehicle.
- FIGS. 2 and 3 are views in cross section and in axial section respectively of the part of the heat exchanger shown in FIG. 1.
- FIGS 4 and 5 are partial perspective views of two other heat exchangers according to the invention.
- FIG. 6 is a partial view at the end of the exchanger of FIG. 5.
- FIGS 7 and 8 are partial views in longitudinal section and from the side of this same exchanger.
- the heat exchanger shown in Figures 1 to 3 comprises a manifold formed essentially by a solid metal body 1 having externally the general shape of an elongated cylinder of revolution.
- the body 1 is pierced with an axial through bore 2 which gives it the shape of a thick-walled tube.
- the body 1 is for example produced by extrusion.
- Transverse slots 3 regularly spaced from each other in the axial direction, are formed in the body 1.
- Each slot 3 is elongated horizontally, as seen in Figure 2, and opens out of the body at its two ends as well only down its entire length. Its bottom is also interrupted by the bore 2, which is thus in fluid communication with the slot.
- Each slot serves to receive the upper end of a vertically elongated tube 4, as seen in the figures, and having two main faces situated in respective planes perpendicular to the longitudinal axis A of the body 1 and the bore 2, giving it an elongated cross section from left to right in FIG. 2.
- Each tube 4 is pierced with a multiplicity of longitudinal channels mutually aligned according to its width (that is to say along the length of its cross section), these channels defining separate paths for the circulation of the fluid.
- the tubes 4 are mutually aligned in the direction of the axis A, alternating with spacers 6 each consisting of a corrugated strip, the crests of a corrugated interlayer coming into contact alternately with the two tubes which frame it.
- the width of the tubes is greater than the diameter of the bore 2, so that only the channels 5 located in a median region of this width open directly into the bore 2, while the other channels open out into look at the thick wall of the body 1, on either side of the bore, as can be clearly seen in FIG. 2.
- the bottom of the slots is located at two different levels. On each of the longitudinal sides of a slot, the bottom 7 thereof is at a lower level and forms a stop for the lateral edges of the end of the tube 4.
- the ends of the slots 3 open to the outside of the body 1, and must therefore be closed to ensure leak-tight communication between the channels 5 and the bore 2.
- the body 1 rests, by the lower half of its surface , in a cradle 10 in rolled sheet.
- Each of the lateral edges 11 of the cradle 10 is provided with a series of teeth 12 which hook onto a longitudinal recess 13 provided on the corresponding side of the body 1.
- Figures 1 and 3 still show a transverse partition
- One or more transverse partitions can thus be provided, to axially limit the interior volume of the manifold and / or divide it into different chambers.
- the cradle 10 has openings 17 elongated transversely, of a size just sufficient for the passage of the tubes 4.
- the cradle is brazed to the body 1, to the tubes 4 and to the partition 14, by means of a brazing applied for example on its entire concave upper surface, thus ensuring the seal between the bore 2, the slots 3 and the channels 5 on the one hand, and the exterior on the other hand.
- the partition 14 must also be brazed to the wall of the bore 2 to ensure the sealed separation thereof.
- Figures 1 and 3 show a thread 19 provided at one end of the bore 2 for the screwing of a fluid inlet or outlet nozzle.
- the lower ends, not shown, of the tubes 4 can be in communication with a lower manifold similar to the upper manifold, as is the case in the heat exchanger shown in FIG. 4, where elements similar to those described above are given the same reference numbers increased by 20, and will not be described again in detail.
- This second heat exchanger comprises tubes 24 similar to the tubes 4 described above, and two manifolds whose bodies 21 differ from the body 1 in that each of them has not one, but two longitudinal bores 22 whose axes are parallel and located in the same horizontal plane, for a vertical orientation of the tubes.
- the two bores of each body 21 are therefore separated one from the other by an intermediate longitudinal wall 38.
- Transverse slots 23 similar to the slots 3 are formed in the bodies.
- the deepest part of each slot therefore defines, in addition to two horizontal conduits 29 each of which connects a bore 22 to the adjacent end of the slot, a horizontal conduit 29a connecting the two bores to each other, and into which the circulation channels open out. 25 located in a central region of the width of the tube 24. It is also possible to provide that the channels 25 located in the marginal regions of the width of the tube open beyond the bores 22, that is to say in the conduits 29, as is the case for the heat exchanger of FIGS. 1 to 3.
- Each cradle is associated with a cradle 30 which, in addition to its shape adapted to the width of the body 21, differs from the cradle 10 described above in that the teeth 12 are replaced by flanges 32 projecting in the direction of the longitudinal plane. median of the heat exchanger and cooperating over the entire length of the cradle with a corresponding lateral offset 33 of the body.
- each collecting box comprises a solid body 41 of a generally cylindrical shape similar to that of body 1, and traversed like this by an axial bore 42 cylindrical of revolution.
- Each body 41 is associated with a cradle 50 in stamped sheet metal.
- Each end of the tubes 44 is capped by a bowl 60 formed by the stamping of the cradle, the bottom 61 of this bowl fitting into a transverse notch 62 of the body 41, which communicates with the bore 42 and which opens at its ends on both sides of the body.
- An opening 63 crossing the bottom 61 at its center allows communication of fluid between the bore 42 and the channels 45 of the tube, the tightness of this communication being ensured by brazing the bowl by its internal face at the periphery of the tube and by the external face of its bottom at the notch 62 of the body.
- each cradle 50 to the corresponding body 41 is carried out by means of lugs 64 belonging to the cradle, arranged in pairs on either side of the body, the pairs of lugs being arranged alternately with the bowls 60.
- Each leg 64 is turned away from the interlayer 66, that is to say upwards for the upper cradle and downwards for the lower cradle, and ends with a tooth 65 which projects in the direction of The axis of the body to cooperate with a longitudinal step 53 of the latter, in the same way as the teeth 12 of the heat exchanger of FIGS. 1 to 3.
- transverse partition 54 which is introduced in the same way as the partition 14 of Figures 1 to 3 through an opening 56 of the body 41 facing the bundle of tubes, to define a chamber 55 in the bore 42.
- this partition projects beyond the opening 56, to form the starting base of two legs 66 which extend in the circumferential direction along the body 41 until the recesses 53, on which they hook onto end teeth 67 which act in the same way as teeth 65.
