Definitions

  • the invention relates to a heat exchanger according to the preamble of claim 1.
  • FIG. 1 a stacked plate heat exchanger is shown, which consists of different arranged over each other elongated discs 2, each having a turbulence insert.
  • the turbulence insert 3 is lasered and punched and adapted in this way the shape of the disc 2.
  • the overlying discs 2 are arranged on a base plate 4. Through holes 5, which are used to guide the medium to be cooled or to guide the coolant, are formed at the end regions of each disk 2.
  • the stacked plate heat exchanger 1 is completed above the discs 2 with a flange F, which is the interface to the engine and for coolant management.
  • the discs 2 themselves are stamped or deep-drawn moldings. For the production of such moldings tools must be made, with different sizes of the discs 2 more tools are required.
  • the invention is therefore based on the object to provide a heat exchanger which can be variably manufactured and in which the investment costs for tools, in particular for prototypes or small series, are reduced.
  • the object is achieved by the features of the characterizing part of claim 1.
  • These have the advantage that the frame is simply cut out of a metal sheet by laser beams or jets of water, the course of the laser or water jets being controlled by a computer.
  • any computer-controlled laser or water jet tool with a special forming computer program is used for the preparation of the frame.
  • the production of an expensive tool is completely eliminated, whereby the investment costs are significantly reduced or completely eliminated.
  • Such a computer program can be easily varied, so that frames can be made in a variety of sizes and quantities, without the cost increases dramatically. This further reduces the development times for a heat exchanger. Since the heat exchanger can adopt any possible external contour due to the invention, an optimal use of space or adaptation to the available space in the motor vehicle is made possible.
  • the frame encloses the turbulence insert completely and in particular has an approximately rectangular shape.
  • the turbulence insert is held by the frame, wherein the height of the frame is matched to the height of the turbulence insert.
  • the turbulence insert only has to be punched out of a larger piece. A trimming of the turbulence insert to adapt to the shape of the frame is eliminated, which further reduces the manufacturing cost of the heat exchanger.
  • a separating arrangement is inserted between two layers each consisting of the frame and the turbulence insert. This separation arrangement separates the media streams of the medium to be cooled and the coolant. Since the separating arrangement is easy to produce either from a foil or from a thin sheet, the production costs for the heat exchanger are also reduced in this case.
  • the disk-like separation arrangement has a solder layer on both sides.
  • the heat exchanger based on frame in its geometry corresponds to a stacked plate heat exchanger, so that the corresponding flanges after assembly the heat exchanger can be placed as a conclusion on the heat exchanger, can also be used for the realized in frame construction heat exchanger. This eliminates the need to make new flanges for the heat exchanger manufactured in frame construction.
  • the first through-hole to the inlet of the medium to be cooled and the second through-hole to the outlet of the medium to be cooled are formed diagonally opposite or only opposite to each other in the frame.
  • the frame for receiving a mounting aid on a guide opening ensures that the overlaid frames also coincide exactly, so that the through holes to the inlet or outlet of the medium to be cooled or the cooling medium are reliably superimposed.
  • the guide opening is formed between the through hole and the energy lock.
  • the frame has at least one identification cam on its outer edge.
  • This identification cam has the advantage that it leaves a symmetrical pattern on the outside of the heat exchanger after installation of the heat exchanger, so that the person performing the coffering can immediately determine whether the individual frames are in the correct position relative to one another.
  • FIG. 2 shows a frame 6 as cut out by a computer controlled laser or water jet tool.
  • the frame 6 is approximately rectangular in shape and has in its longitudinal extent two web-shaped longitudinal edges 7 and 8, while at the narrow sides end portions 9 and 10 are widened.
  • the end region 9 comprises an inlet 11 for a liquid medium, a channel closure 13 for a liquid medium and a guide opening 14 for an assembly aid. Diagonally opposite to the channel closure 13 of the end region 9, a channel closure 13 is likewise formed in the end region 10.
  • the outlet 12 for the liquid medium of the end portion 10 is diagonally opposite the inlet 11 in the end portion 9.
  • the guide openings 14 are arranged so that they lie symmetrically in the formation of the frame 6.
  • FIG. 3 a separating arrangement is shown, which is designed as a cutting disc 15 and which is adapted to the outer contours of the frame 6 in their outer contours.
  • the cutting disk 15 is formed flat and has at its narrow ends openings 16 and 17, which are formed approximately oval and the channel closure 13 and the inlet 11 or the outlet 12 of the frame 6 span.
  • the centrally disposed opening 18, which is formed on both sides of the cutting disk 15, lies exactly below the guide opening 14.
  • FIG. 4 shows how the in FIG. 2 and 3 shown frame 6 and the blade 15 are mounted over each other.
  • the frame 6 rests on the cutting disk 15, wherein the interior of the frame 6 is filled by a turbulence insert 19.
  • This turbulence insert 19 is simply inserted into the frame 6 and only has to be punched for this purpose. Cutting the turbulence insert 19 to a specific shape is eliminated.
  • the frame 6 has an identification cam 20 at an end region 10.
  • the channel closure 13 is provided with a web 21, which allows a particular stability of the frame 6. By the web 21 it is ensured that the frame 6 can not bulge in the end region 9, 10.
  • FIG. 5 the cutting disk 15 and the frame 6 are alternately stacked and positioned on a base plate 22.
  • the frame 6 does not have the turbulence inserts.
  • FIG. 5 the position of a frame 6a can be seen.
  • the end portion 9 of the frame 6a is positioned on the left side of the base plate 22 while the end portion 10 of the frame 6a is located on the right side of the base plate 22.
  • the inlet 11 of the liquid medium end region 9 is located diagonally opposite the liquid medium outlet 12 in the end region 10 of the frame 6a.
  • the guide openings 14 are arranged opposite lying. Also, the channel closure 13 of the end portion 9 and the end portion 10 are in this positioning of the frame 6a diagonally opposite.
  • FIG. 6 a second position of a further frame 6b is shown, which is above, in connection with FIG. 5 explained frame 6a is positioned.
  • the frame 6b compared to the frame 6a of FIG. 5 rotated by 180 ° about its longitudinal axis.
  • the channel shutter 13 of the end portion 9 is now positioned at the position where the inlet 11 is positioned at the underlying frame 6a.
  • the channel closure 13 and the outlet 12 are also interchanged with each other.
  • the turbulence insert 19 is inserted into the frame 6b.
  • the medium to be cooled from the inlet 11 can escape and flows in the longitudinal direction of the frame 6 b through the turbulence insert 19 to flow out of the outlet 12 from the frame 6 b again.
  • FIG. 7 a fully manufactured oil heat exchanger is shown, in which a plurality of frames 6a, 6b are stacked over each other, wherein the frame 6a, 6b are separated by a cutting disc 15.
  • the turbulence inserts 19 are only indicated in this example.
  • the frames 6a, 6b are alternately, separated by a cutting disk 15, mounted on the base plate 22 and are closed by a flange 23.
  • the cutting discs 15 are coated on both sides with a solder prior to assembly, which leads to the fact that in a soldering process, the frame 6a, 6b and the turbulence insert 19 are firmly connected to each other.
  • FIG. 8 a charge air cooler is shown in the illustrated frame construction, wherein here too the frames 6a, 6b are arranged alternately on a base plate 22, wherein the frames 6a, 6b are separated by a respective separating disk 15.
  • the different channels for the permeability of the air used as a coolant or the medium to be cooled can be seen particularly clearly in this section.
  • the air-side profile is marked, while with the arrow 25, the coolant-side profile is shown.
  • the intercooler is covered with a flange 23.
  • FIG. 9 is a fabricated in frame construction heat exchanger 27 is inserted into a soldering device 26.
  • the heat exchanger 27 is supported on a guided by four guide pins 32 first plate 28, wherein between the first plate 28 and a second plate 29 a plurality of springs 30 are arranged.
  • 27 is a bolt 31 a, 31 b introduced through the guide openings 14 of the heat exchanger.
  • An end plate 33 covers the heat exchanger 27 from.
  • the end plate 33 is adjusted at the openings 34 of the guide pin 32 such that the heat exchanger 27 is biased against the springs 30.
  • the cutting discs 15 are provided on both sides with a layer of solder.
  • Heat exchanger 27 is pushed in a soldering furnace, where during a soldering process, the heat exchanger is soldered in its individual parts with each other.
