Definitions

  • the invention relates to a flat tube condenser according to the preamble of claim 1.
  • a flat tube condenser is known from EP-A2 0 255 313.
  • the collector is shaped as a cylinder, which is internally coated with solder.
  • the flow cross section can only be increased by increasing the radius. Among other things, this has an undesirable influence on the overall depth of the flat tube condenser or a corresponding flat tube evaporator.
  • the insertion slots for the flat tubes of partition walls to form separate sections of the collector can only be produced in a relatively complicated manner, in particular by milling.
  • the invention is based on the object of designing the collector of a flat tube condenser or flat tube evaporator in such a way that it combines the stated advantages of the two mentioned possible solutions without having the disadvantages mentioned.
  • This largely free cross-sectional design can be combined with a pre-coating of the unbent flat parts with solder. This solder is then used not only to connect the collector to the flat tubes inserted into the insertion slots, but also to make use of the flat parts in their two overlapping areas in additional use.
  • solder only the first flat part provided with the insertion slots for the flat tubes.
  • the quality of the connection of the two flat parts, or at least the security of the solder connection can be further improved in the sense of claim 2 if the second flat part is also provided with solder.
  • This solder can then also be used for soldering an intermediate wall, which may not be coated with solder, which is used to divide the collector into individual, separate chambers, or also end covers (see also claim 8), even if these are not included Are solder coated.
  • the second flat part can be reduced to a pure lid function.
  • the first flat part overlaps the second flat part on the outside, for example if one wants to use maximum width in the first flat part for the insertion slots of the flat tubes; because in such a case the available width is increased by two material thicknesses of the first flat part.
  • the two flat parts are also clinched to one another in the two overlapping areas in addition to their solder connection.
  • Any known clinching method can be provided as a clinching, in particular a linear or a punctiform or zone-wise pressing, these pressing on the one hand lengthways straight circumferential lines or curved lines and on the other hand with engagement in recesses of one of the flat parts or preferably (cf. also claim 7) can only take place with deformation of closed walls.
  • the overlap is developed into a pocket-like engagement, so that in the clinching area or overlap area two walls of one flat part encompass a third wall of the other flat part.
  • the solder gap can be kept as small as possible, for example with preferred hard solder, in particular AlSi7.5 to AlSi10, to less than 0.1 mm and, in addition, pre-assemble the two flat parts for their soldering as a whole and also against one Secure the relative shift yourself during the soldering process.
  • preferred hard solder in particular AlSi7.5 to AlSi10
  • a further advantage can also be achieved.
  • an exposed free end of the edge section which forms the outer wall of the insert pocket, can be used as an insertion bevel before soldering.
  • the invention makes it possible to design the insertion slots and / or the receiving slots as punched slots, which can even be pre-formed in the unbent first flat piece.
  • Both the character of the slots as punched slots and their formation on the initially unbent flat piece can be determined by microscopic examination of the collector even after it has been installed, e.g. through appropriate microscopic examinations.
  • claims 13 and 14 relate to preferred forms of bending of the two flat parts.
  • the free clear cross section can be easily adjusted in the case of claim 14 by appropriate choice of the length of the straight leg of the U-profile of the second flat part without having to accept significant losses in compressive strength.
  • the invention can be implemented with horizontally extending flat tubes. This is also the normal scope. Claim 15 also allows an alternative with a vertical arrangement of the flat tubes, which is of particular interest in certain installation conditions in the motor vehicle. So far, such condensate flow arrangements of the condensers have been avoided in order to avoid a pulsation of the refrigerant flow due to periodic blockage by liquid components of the refrigerant with subsequent breakdown of gas components. Separation of oil components of the refrigerant in the lower collector is particularly critical.
  • a vertical profile of the flat tubes and thus a horizontal profile of the collectors can also be used favorably, in particular in the application according to claim 24 for cross-flow coolers of a vehicle, primarily a motor vehicle.
  • the water boxes of the vehicle cooler, which serve as collectors, on the one hand, and the collectors of the flat tube condenser according to the invention, on the other hand, are greater in construction depth than the aforementioned tube-lamella system of each individual unit.
  • this insert pocket can additionally be used either for installing the entire flat tube condenser in the vehicle concerned, e.g. Motor vehicle, make usable or use as a holder for additional units.
  • Liquid collectors, dryers for the refrigerant and the like can be considered as additional units.
  • the insert pocket in question can be left completely unmodified, for example, according to application claim 23, and can be attacked on it, for example, simply from the outside with a clamp connection or clinching.
  • the insert pocket from the outset in the sense of claim 16 as a carrier for attaching retaining plates for fastening to a vehicle body or for receiving additional units.
  • a preferred preparation measure is that of claim 17 with through mounting holes, which are harmless for the collector function here.
  • Claim 19 is not only related to the readily understandable case of vertically arranged collectors, but can also be realized with horizontally arranged collectors in the sense of claim 15; this special case of horizontally arranged collectors could even be realized with a different construction of the collectors than according to the invention.
  • the case is generally considered that in a horizontal header located below, the refrigerant is fed vertically at one end and drawn off vertically at the other end. Liquefied refrigerant then collects not only under the force of gravity but also under centrifugal forces as a result of the U-shaped deflection at the base of the collecting tube. If the drain openings provided according to claim 19 are arranged in the partition at the bottom of the collector, liquefied refrigerant can flow horizontally to a drain.
  • the horizontal collector at the top can be designed without drain openings in the intermediate walls.
  • a solder coating on the collector part is usually a roll-on layer of, for example, 10% of the material thickness. Roll-on layers of this type have relatively smooth surfaces. If you want to carry out the soldering in a modern way as vacuum soldering, however, the layer of the solder must be pickled to prevent surface oxidation, grease deposits and the like. the like. This leads to a subsequent surface roughening, which in this case can lead to problems with flat tube condensers according to claim 6, if only the usual soldering gap of 0 to 0.1 mm is left on the exposed area of the free end of the edge section of the inner flat part. Then, in this area, the surface roughness can significantly impede or even make it impossible to insert the free edge of the outer flat part into the insertion pocket.
  • the outer flat part is only partially inserted into the insertion pocket on the inner flat part, so that height and shape tolerances of the assembly can be compensated for in the case of the tolerance-sensitive shaped flat parts.
  • a relatively large gap width of the insertion pocket is provided in the sense of the method according to the invention for uninhibited insertion, while a smaller gap width is expedient for soldering.
  • a risk of tearing there is a risk of tearing if an aluminum or aluminum alloy sheet with solder coating is flanged several times.
  • Claim 22 relates to the use of the type of collector according to the invention, which has already been mentioned several times, instead for a flat tube condenser instead for a flat tube evaporator.
  • the collector 10 is designed according to the embodiment according to FIG. 3.
  • the flat tubes are each designated 2 and the fins 4.
  • the ends of the flat tubes 2 are each inserted into the tube sheets of collectors 10, on each of which a connector 6 is placed on the refrigerant inlet of the flat tube condenser and a connector 8 on the side of the header 10 facing away from the fins 4 is pressure-tight at the refrigerant outlet of the flat tube condenser.
  • the collectors 10 serve to combine several flat tubes 2 in groups. For this one could use individual collectors 10 per group (see FIGS. 11 and 12). In a conventional manner, however, a single collector tube is used according to FIG. 1, which extends over the entire collector height and which is divided by partition walls 14 into individual collector sections which are sealed off from one another within the collector and each perform the function of an individual collector. In practice, this does not conflict with the fact that in the collector provided with the connections 6 and 8 at the heights at which the refrigerant is already partially liquefied, drain openings 12 are provided in the intermediate walls 14 for refrigerant that has already liquefied. The partitions in the other collector and the top partition of the former collector are not broken.
  • the cross section of the drain openings 12 increases in the perforated partition walls from partition wall to partition wall speaking of the increasing mass fraction of liquefied refrigerant.
  • This serves as a valve body in order to completely or substantially close the outlet openings 12, ie at least 90% mass flow, for the gaseous phase of the refrigerant. This reduces the amount of liquid refrigerant in the lower flat tubes, so that more inner surface can be used to liquefy the refrigerant.
  • Both the flat tubes 2 and the fins 4 are suitably made of aluminum or an aluminum alloy.
  • the flat tubes are expediently made of the wrought aluminum alloy AlMn1 according to DIN standard.
  • the lamellae made of the same material or, if they are to be hardenable after soldering, can expediently also consist of AlMgSi alloy.
  • An aluminum alloy of AlSi7.5 to AlSi10 is expediently used as the solder, the fluxes customary for such alloys being used, such as, for example, chloride- or fluoride-containing fluxes, in the simplest case, table salt suspended with commercially available additives.
  • the flat tubes 2 covered with fins 4 extend in register between two parallel collectors 10.
  • One collector is provided with the two connectors 6 and 8 for the refrigerant to be liquefied.
  • the parallel flat tubes 2 each engage through a slot 36 in the collector 10, which can be seen from FIGS. 3 and 4.
  • the two alternative embodiments of FIGS. 3 and 4 are the same with regard to the connection method of the flat tubes 2 engaging in the slots 36. In FIG. 3, only the cut through an area between adjacent flat tubes is selected, while in FIG. 4 the cut is passed through the slot 36 itself. The cuts can be transferred alternately to both embodiments of FIGS. 3 and 4.
  • the collector jacket 62 of the collector 10 consists of two curved flat surfaces that overlap one another and are soldered to one another in both overlap regions 64 parts 66 and 68 is composed of Al or an Al alloy.
  • the so-called first, flat part 66 is provided with the aforementioned insertion slots 36 for receiving a flat tube 2 each, and is also coated with solder, in particular hard solder, for soldering to the flat tubes 2 and the second flat part 68. If the partitions 14 are used in the sense of FIG. 1, the solder also serves for soldering to them.
  • the second flat part 68 essentially has a lid function supplementing the collector jacket 62; it is also preferably coated with solder, here for soldering to the first flat part 66 and possibly also with the intermediate walls 14. Likewise, the solder of both flat parts can also be used for soldering with end covers 70.
  • solder layers not specifically shown in the drawings locally in the area of their soldering application or only on one side of the flat part, which later forms the inside of the collector.
  • commercially available flat materials coated on both sides will be chosen to form the flat parts. These are, for example, deformed into the application form by bending and / or deep drawing.
  • the second flat part 68 overlaps the first flat part on the outside, so that in the exemplary embodiments described here the first flat part 66 can also be understood as an inside flat part and the second flat part 68 as an outside flat part, without this preferred assignment being mandatory is.
  • FIGS. 3 and 4 differ first of all in the way they overlap.
  • the embodiment according to FIG. 4 is a simple two-layer overlap.
  • the embodiment according to FIG. 3 is a three-layer overlap, in which in the two overlap areas 64 the inner or first flat part 66, the two free edges 72 of the outer or second flat part 68, each forming the respective edge 72 insert pocket 74 encompassing on both sides and running along the collector 10 with its edge section 76 encompasses.
  • FIGS. 3 and 4 two different types of clinching in the respective overlap region 64 are illustrated on the two FIGS. 3 and 4.
  • the cutouts 80 can also be dispensed with and the overlapping walls can be deformed together with a common embossing and thereby brought into positive engagement.
  • an indentation in the manner of indentation 78 of FIG. 4 would be formed through all three walls of the overlap in a manner not shown, without material intervention in a recess.
  • an engagement in a recess can also be provided with a three-layer connection. Preferred designs of this three-layer connection are described in more detail with reference to the following figures.

  • the free cross section of the collector can be set up according to how much of the free leg 84 to form the inner cross section of the collector jacket and how much is consumed in the overlap area. You can also work with different leg lengths.
  • the first flat part 66 can also be designed with a semi-cylindrical or other curved arch part 86 with two parallel straight legs 88 extending from it.
  • This arched part 86 can in turn not only be semi-cylindrical, but also arched differently. This is particularly clear from the also on Fig. 4 transferable vault shape according to FIG. 3, which is shaped in the manner of a dished bottom 44.
  • the free edges 72 of the legs 84 of the outer second flat part 68 preferably (but not necessarily) extend to the bottom of the respective insertion pocket 74, but instead each have an end gap 90 above the base leave the respective insert pocket free.
  • the flat tubes 2, which are connected to one another in a block-like manner by the fins 4, are inserted together as a structural unit into the insertion slots 36 of the first flat part.
  • This first flat part also has, in the transition region into the insertion pockets and at the suitable location between adjacent insertion slots 36, two additional receiving slots 92, aligned with one another, for insertion feet of a partition disk-like intermediate wall 14, which divides the collector into individual departments.
  • the same also applies to the vicinity of the two ends of the first flat part 66 corresponding receiving slots 92 to be arranged in each case after the last insertion slot 36 for the end covers 70 already mentioned earlier.

  • the insertion of the free edges 72 of the outer flat part 68 into the respective insertion pocket 74 can in principle be simplified if the free end 108 of the edge section 76 is exposed to the outside as an insertion bevel (straight or convex).
  • this bevel formed in the originally shaped flat piece is indicated in dashed phantom drawing.
  • This original bevel is pressed against the relevant free edge 72 of the outer flat part when the clinch connection is made.
  • the outer layer of the insert pocket 74 is deformed in such a way that a pronounced contact edge 110 of the edge section 76 is formed on the free edge 72 of the outer flat part 68, from which the insert pocket is approximately in its original configuration towards the bottom bulges out.
  • gap widths b of at least 3/2 times the material thickness of the free edge 72, in practice the upper limit of b can be, for example, two to three material thicknesses of this free edge. Only after being plugged together are the two outer walls of the relevant insertion pocket 74 pressed together to grip the inner free edge 72, in order to be subsequently clinched and in any case soldered to one another.

  • the overall depth is nevertheless only slightly greater than the sum of the overall depths of the two tube fins Systems plus the minimum space 136, since the manifold 10 of the flat tube condenser and the water boxes 132 of the crossflow cooler extend in a frame-like manner around the series connection of the two tube-lamella systems mentioned and thus do not take away one another from each other.
  • FIG. 15 also illustrates another possibility for mounting the flat tube condenser in the body 160 of a motor vehicle or other vehicle.
