Definitions

  • the invention relates to a heat exchanger mentioned in the preamble of claim 1.
  • the invention has for its object to provide a heat exchanger of the type mentioned, in which the sealing elements are simplified and the prerequisites for a simpler and cheaper production are created.
  • the sealing elements preferably have plates made of metal as part, these plates can be used for flow guidance, as assembly aid and soldering aid and, if necessary, firmly connect them to the tube package, these plates also holding surfaces for the elastic lips, which here are made of separate sealing profiles are formed, which are releasably attached to the plates, provide.
  • This makes it possible to use the plates to pre-assemble the unit consisting of the tube package and, for example, the support plate, and to use the plates as assembly and soldering aids for subsequent soldering without the sealing profiles already being attached.
  • a heat exchanger 10 for liquid media is shown, in particular an oil cooler.
  • This has a tube pack 11 of a conventional type, which is designed here in particular in a disk construction and thus has individual flat tubes 12 arranged one above the other, between which, for example, lamellar or zigzag-like guide elements 13 are arranged, the flat tubes 12 being connected to one another with regard to their interior.
  • the tube packet 11 has an inlet 14 for the introduction of the medium, for example water or oil, and an outlet 15 for the discharge of this medium.
  • a cover is arranged on the top of the tube packet 11, which serves as a support plate 16 of the tube packet 11 and is connected to it that is.
  • the unit consisting of the support plate 16 and the tube package 11 is inserted into a housing 20, which is either a separate housing for the heat exchanger 10 or can instead be part of a motor or transmission housing or the like.
  • the housing 20 is e.g. represented in a simplified trough-shaped manner and with an inlet 21 for a medium to be introduced, e.g. Oil or water, and provided with a drain 22.
  • a medium to be introduced e.g. Oil or water
  • sealing elements 30 are arranged between the sides of the tube packet 11 and the housing walls 23 and 24 adjacent to these sides, to be precise in an area which is in the flow direction is located between the inlet 21 and the outlet 22.
  • sealing elements 30 are attached to the tube package 11, so that the tube package 11, hanging on the support plate 16, can be inserted into the housing 20 together with the sealing elements 30.
  • the sealing elements 30 are provided with elastic lips 31 e.g. made of plastic, which bridge the distance left between the tube package 11 and the housing walls 23 and 24 and are directed against the housing walls 23, 24.
  • the sealing elements 30 have plates 32, 33 and 34, which preferably consist of metal and in particular aluminum, but instead can also consist of copper, brass or the like material.
  • the elastic lips 31 provided on these plates 32 to 34 are formed from separate sealing profiles, of which only the sealing profile 35 on the plate 32 (FIG. 2) and the sealing profile 36 on the underside plate 33 (FIG. 1) are visible in the drawings are. It goes without saying, however, that a sealing profile is also attached to the other plate 34, which runs approximately parallel to plate 32.
  • sealing profiles 35, 36 are attached to the edges 37, 38, 39 at the left end of the plates 32, 33 and 34 in FIGS. 1 and 2. As can be seen in particular from FIGS. 1 and 2, the sealing profiles 35, 36 are thus provided on the end region of the plates 32 to 34 on the left there, which is adjacent to the inlet 21 of the housing 20, preferably directly adjoins it.
  • the individual plates 32 to 34 are advantageously connected to one another. They result from a plate part 29 which is approximately U-shaped in cross section, as can be seen in particular from FIG. 3.
  • the plate part 29 is preferably a bent part. It is designed and dimensioned such that it comprises the tube packet 11, two opposite side walls of the plate part 29 forming the two plates 32 and 34 which cross the tube packet 11 on facing sides and a bottom of the plate part 29 which the tube packet 11 on the in Fig. 1 below bottom plate 33 forms.
  • Such a one-piece plate part 29 is simple and inexpensive, in particular as a bent part.
  • the side walls and the bottom of the plate part 29, which form the plates 32 to 34 can advantageously extend over a substantial length of the tube packet 11, preferably e.g. approximately over the entire length, viewed from left to right in FIG. 1.
  • the plate part 29 with its right end in Fig. 1 is approximately flush with the end of the tube packet 11 there.
  • the plate part 29 with the other end which is on the left in FIGS. 1 and 2 and which faces the inlet 21, projects in the longitudinal direction beyond the adjacent end of the tube stack 11 which is on the left in FIGS. 1 and 2.
  • the protrusion dimension is dimensioned approximately as large as the width of the edge 37, 38 and 39, to which the associated sealing profile 35, 36 is applied, in particular attached.
  • the sealing profiles 35, 36 attached to the edges 37 to 39 can consist of individual connecting sealing profiles. Instead, however, it is particularly advantageous and simple if a single circumferential sealing profile is present, which is connected to the approximately U-shaped profile shown in FIGS. to the left protruding end of the plate part 29 is attached, in particular is attached, and thus contains the sealing profiles 35, 36 located on the edges 37 and 38 in one piece.
  • a sealing profile consisting of one part can be attached particularly quickly and easily to the end of the plate part 29.
  • the sealing profiles 35, 36 or the only sealing profile connecting them in one piece consist of plastic or instead of rubber, synthetic rubber or the like suitable material. They are attached with a groove 40 contained therein to the respective edge 37 to 39 of the plates 32 to 34.
  • the width of the groove 40 is expediently dimensioned such that a clamping bracket already takes place when it is attached. Because of this groove 40, the sealing profiles 35, 36 or the only one that connects this one-piece sealing profile in cross-section approximately corresponding to a lying U.
  • the outer leg 41 of the sealing profiles 35, 36 bears against the respective longitudinal housing wall 23 and bottom housing wall 24, where it seals to avoid a bypass flow.
  • the sealing profile 35, 36 for example, with the part 42 forming the base of the U, only abut the facing, front end wall 25 of the housing 20, through which the inlet of the medium occurs via the inlet 21, without contacting the other housing walls 23.24.
  • the respective sealing profile 35, 36 lies in a sealing manner on the two longitudinal housing walls 23, on the housing wall 24 on the bottom side and additionally on the facing end wall 25.
  • the part 42 of the respective sealing profile 35, 36 can also rest with a sealing lip 43 with a reduced cross section.
  • the plates of the plate part 29, here e.g. the plates 32 and 34 on both sides pass with bulges 28, which are here e.g. extend transversely and protrude toward the associated longitudinal housing walls 23 against which they can rest.
  • Bulges 28 of this type increase the rigidity of the plate part 29. They also bring about centering and secure mounting of the tube pack 11 accommodated in the housing 20, since they represent spacer elements on both sides that bridge the gap.
  • these bulges 28 can also have further bypass barriers, e.g. against backflow in the housing 20.
  • the plate part 29 is designed in a particularly advantageous manner as a holder for the inserted tube package 11, in particular for a soldering process following the assembly.
  • the plate part 29 has projections 27 at the end facing the support plate 16, e.g. Rags that engage for attachment to the support plate 16. In the exemplary embodiment shown, four such projections 27 are provided, which are integral parts of the plate part 29.
  • the support plate 16 contains openings 17, e.g. Slots that can be penetrated by the projections 27.
  • the plate part 29 also forms an important auxiliary element in its construction as a holder in the manufacture of the heat exchanger 10.
  • the tube bundle 11 is first assembled from the flat tubes 12 and guide elements 13 and then inserted or immediately assembled into the plate part 29, which essentially guarantees the cohesion of the tube bundle 11 even before the soldering by positive locking.
  • the support plate 16 is placed from above, with the projections 27 reaching through the openings 17.
  • the projections 27 are then bent approximately at a right angle, as shown in FIGS. 1 and 4. Then this form-fittingly connected and held together structure is soldered together, e.g. by furnace soldering or the like.
  • the plate part 29 as a holder thus forms a soldering aid for the tube package 11 and the attached support plate 16 during a subsequent soldering process in which the plate part 29 is firmly connected to the tube package 11 and the support plate 16 by soldering, at the same time also the openings 17 contained in the support plate 16 are sealed.
  • the respective sealing profile 35, 36 is only attached, in particular plugged in, after the completion of the unit shown in FIG. 4, consisting of plate part 29, tube package 11 and support plate 16, with the tube package 11 then hanging on the support plate 16 with the attached sealing profiles 35, 36 is inserted into the housing 20.
  • the plate part 29 can also form an independent, separate component in relation to the fully soldered tube packet 11 and the support plate 16 attached to it.
  • the plate part 29 is e.g. subsequently installed as the insert part receiving the soldered tube packet 11 in order to prevent a bypass flow in the manner described at the beginning.
  • a subsequent installation of the plate part 29 with sealing profiles 35, 36 in an already existing heat exchanger 10 is possible in this way, so that heat exchangers 10 in operation or in stock can be converted accordingly.
  • the exemplary embodiment shown in FIG. 5 is modified compared to FIGS. 1 to 4 in that in this exemplary embodiment the bulges 28 'provided on the plate 32' protrude towards the tube packet 11 'and the plate 32' with these bulges 28 ', if necessary, on Pipe package 11 'can rest.
  • the plate part 29 e.g. Bulges 28, e.g. Beads, humps or the like, which protrude both towards the walls of the housing 20 and towards the tube packet 11, these bulges 28 e.g. can take turns.
  • the sealing profile 35 ' is also designed somewhat differently. It assigns one in cross section at least approximately wavy and has a sealing lip 44 which tapers in cross section and which bears against the longitudinal housing walls 23 and the lower housing wall 24.
  • the sealing profile 35 ' has a sealing lip 43', which also tapers in a wedge shape in cross section and bears against the end wall 25.
  • the sealing lip 44 which is comparable to the outer leg 41, is pressed outward against the housing walls 23 and 24 by the pressure of the medium flowing into the housing 20 via the inlet 21.
  • the sealing lip 43 ' is pressed against the end wall 25.
  • the invention provides a heat exchanger that can be quickly, easily and inexpensively connected to a unit using the plate part 29 as a soldering aid, without attached sealing profiles 35, 36, which e.g. would otherwise be damaged by soldering.
  • the plate part 29, which is an integral part of the tube package 11 with the support plate 16, provides holding surfaces on which 20 sealing profiles 35, 36 are then quickly and easily, e.g. by attaching, are attachable. If necessary, these sealing profiles 35, 36 can be replaced quickly and easily with new sealing profiles even when dismantled.
  • the plate part 29 acts as a holder during soldering, the preparatory work for the soldering and the soldering itself can be considerably simplified, with corresponding time savings. Since the plate part 29 ensures the cohesion of the tube package 11 for soldering, there is no need for special, costly clamping plates which are otherwise used and which are also exposed to severe corrosion during the soldering process.
