Definitions
- the invention relates to a heat exchanger comprising a multiple pockets mutually stacked in a longitudinal direction and each defining two chambers juxtaposed in a lateral direction so as to make part of a first and second row respectively of rooms, as well as an elementary U-shaped path extending substantially in a plane perpendicular to the direction longitudinal from one to the other of said chambers, for circulating a first fluid in thermal contact with a second fluid, two chambers of the same row, belonging with two pockets adjacent to the stack, being delimited in the longitudinal direction by respective walls applied against each other, some of these walls being provided with openings allowing communication of sealed fluid between the adjacent chambers, the exchanger further comprising an inlet manifold and a manifold outlet for the first fluid, arranged at a first longitudinal end of the exchanger, substantially in the alignment of said first and second rows respectively, and each communicating with one of the bedrooms.
- Such heat exchangers are used in particular as as evaporators in vehicle air conditioning loops, the first fluid being a circulating refrigerant in the loop, and the second fluid being air intended for the passenger compartment of the vehicle.
- the object of the invention is to propose an arrangement of inlet and outlet pipes allowing a reduction of the size of the heat exchanger, both when the first fluid circulates in four passes only when it circulates in six passes.
- the invention relates in particular to a heat exchanger of the kind defined in the introduction, and provides that at least one of said tubes communicates with the corresponding chamber via an end box completing stacking of pockets at said first end.
- Figure 1 is a top view in section of a first mode for producing an evaporator according to the invention.
- Figures 2 to 4 are partial perspective views other embodiments of an evaporator according to the invention.
- FIG. 1 represents an evaporator according to the invention, in section along the plane passing through the axes of the two rows of bedrooms.
- This evaporator consists essentially of a stack of corrugated pockets and dividers such as described for example in FR 2 747 462 A, which can be see for more details on the structure of this stack.
- Each pocket 1 is formed of two plates of stamped sheet in the form of bowls 2 and 3. The latter are identical to each other and have their concavities turned towards each other, respectively upwards and towards the bottom of the figure.
- Each bowl presents, in a plan perpendicular to that of the figure, a peripheral edge 4 and a median junction zone 5 connecting to it at the upper end of the bowl and extending toward the bottom to the vicinity of its lower end.
- peripheral edges 4 and the junction zones 5 of the two pockets forming a pocket are mutually assembled from fluid tight, for example by soldering, to delimit the interior volume of the pouch.
- This volume interior includes two rooms 6 and 7, located on the other of zones 5 respectively to the right and to the left of the figure, defined by deep stampings of plates 2, 3, interconnected by an elementary path in U for the refrigerant.
- Bedrooms 6 and 7 occupy a fraction of the height of the evaporator at the upper part of it, the elementary U-shaped path extending over the rest of the height, behind the plane of the figure, and on a smaller thickness in the direction longitudinal.
- a neighboring plate 2 and a neighboring plate 3 belonging with two different pockets are in mutual support by their bottoms 8 opposite bedrooms 6 and 7, and separate one from the other, opposite the U-shaped paths, by an interval filled with a corrugated interlayer defining a path elementary for the air to be cooled, parallel to the plane of the figure, according to arrow F1.
- Funds 8 in mutual contact are brazed together and some of them are crossed by openings 9 making the corresponding rooms.
- the bottom 8 of the plate 2 located at the end 20 of the stack facing down in Figure 1 is closed so to separate from the outside rooms 6 and 7 adjacent to this plate.
- a box end 10 is arranged beyond the last pocket 1.
- the box 10 is formed of two plates, namely a stamped plate 11 and an end plate 12 substantially plane.
- plates 11 and 12 are tightly connected by annular zones 13 and by vertical median zones 14, delimiting on the side and other of the latter two compartments 15, 16 of the internal volume of the box 10, enveloped by stampings respective of the plate 11 and aligned respectively with the rows formed by chambers 6 and 7.
- Tubing inlet 17 and outlet manifold 18 from the evaporator are fixed on the plate 12 so as to communicate respectively with compartments 15 and 16.
- a tube injection 19 extends longitudinally in the row of chambers 6, crossing the openings 9 which connect these between them, while leaving free a part of the surface of these openings.
- a first end of the tube 19 is located in compartment 15, and its opposite end is located in a room 6 belonging to a space manifold 22 adjacent to the end 20 of the evaporator, formed by a subset of interconnected chambers 6 by openings 9.
- the collector space 22 is limited by direction of the end 21 by a partition 23 crossed by tightly by the tube 19.
- the tube 19 passes through sealingly a partition 24 separating the compartment 15 of chamber 6 adjacent to it, this partition being formed by the bottoms of the stamped plates 11 and 3 delimiting this compartment and this room.
- the bedrooms 6 between partitions 23 and 24 communicate between them by openings 9 to form a collecting space 25.
- the row of rooms 7 is separated by a partition 26 in a collecting space 27 adjacent to the end 20 and a manifold space 28 between the partition 26 and compartment 16 and communicating with it through the opening 9 of the end plate 3 of the stack and a corresponding opening of the plate 11.
- the partition 26 is further from the end 20 than the partition 23.
- the refrigerant entering the evaporator through the inlet manifold 17 first passes into compartment 15, from where the injection tube 19 brings it into the collecting space 22. From the collecting space 22, the fluid travels in parallel the elementary U-shaped paths delimited by the pockets that define it, the branches that communicate with bedrooms 6 and those that communicate with chambers 7 respectively forming a first pass and a second pass, the latter leading to the collector space 27. Likewise, the elementary U-shaped paths of the sleeves included in the longitudinal direction between the partitions 23 and 26 form a third pass and a fourth pass connecting the collecting spaces 27 and 25, and those of pockets between partitions 26 and 24 form a fifth pass and a sixth pass connecting the spaces collectors 25 and 28. Fluid from space collector 28 passes into compartment 16 then leaves the evaporator through the outlet pipe 18.
- the pipes 17 and 18 are offset from each other in the direction vertical, i.e. in the plane perpendicular to the Fig.
- This arrangement has several advantages. She reduces the width (or thickness) of the evaporator, for example below 60 mm, for reasons space in this direction while maintaining a sufficient distance between inlet and outlet pipes for avoid assembly difficulties. It also allows, if this is desired to meet the needs of the connection from the evaporator to the rest of the air conditioning loop, bend the inlet and outlet pipes to bring them in the lateral direction, while being arranged one above on the other to limit the space in the longitudinal direction.
- the injection tube 19 is advantageously offset from the centers of the openings 9 to the right, that is to say downstream of the air flow F1.
- FIG. 2 schematically represents an evaporator according to the invention in which the refrigerant circulates in four passes.
- This evaporator includes a stack of pockets and dividers as described above, only a plate 3, belonging to a terminal pocket, and a tab 100 being shown.
- a stamped plate 111 which forms with a plate substantially flat 112 an end box 110.
- a tube injection 119 similar to the tube 19 of FIG. 1 is linked from sealingly against an inlet pipe 117 situated opposite from the outer face of the plate 112, the whole through sealingly this plate.
- An outlet pipe 118 fixed so as to project also on the face plate 112 external, communicates with the interior volume unit 115 of the box 110, which surrounds the tube 119.
- a partition not shown separates into two collecting spaces the chambers of the row through which the tube 119 passes. however, the bedrooms on the other row all communicate between them to form a single collector space, and are separated from the interior volume 115 by the bottom of the pressed plate 111.
- the refrigerant entering through the inlet pipe 117 passes directly into the injection tube 119 which brings it in the collector space of the first row most away from the tubing 117.
- the fluid circulates in the basic U-shaped journeys along a four-pass route which brings it back to the collecting space of the first row adjacent to box 110, from where it gains interior volume 115 by an annular passage defined, around the tube 119, by an opening 109 of the plate 3 adjacent to the plate 111 and an opening 130 of the latter.
- the fluid leaves volume 115, and the evaporator, via the outlet pipe 118.
- the plates 111 and 112 extend over the entire height of the evaporator, the part 131 of plate 111 located lower than the interior volume 115 being plane and vertical is attached to the plate 112. These two plates have recesses 132, 133 intended for lighten the evaporator.
- the evaporator of figure 3 differs from that of figure 2 only by removing the planar portion 131 of the plate 111, below its annular zone of junction with plate 112, which of course does not affect way the operation of the evaporator.
- Figure 4 shows similar plates 111 and 112 to those of Figure 3, made by cutting, stamping and folding from a single flat sheet.
- the plate 111 obtained after cutting and stamping, disposed above the plate 112, its edge peripheral 113 being located in the plane of plate 112.
- the final position of the plate 111 is obtained by a 180 ° rotation around a horizontal fold line, according to arrow F2.
- the indications relating to the orientation or the position in space of the elements is refer to a particular orientation of the evaporator, and must therefore be adapted if this is changed.
