Definitions

  • the invention relates to extruded or extruded cooler tubes for countercurrent, cocurrent or crossflow coolers with continuous and half webs.
  • the known cooler tubes which are provided with continuous and half webs, are provided as heat exchangers in particular for oil and charge air coolers.
  • These pipes belong to the class of technically smooth pipes, in which the medium flows quickly; the corresponding heat exchange is too low for many types of application and must therefore often be compensated for by unnecessarily large dimensions of the cooler tubes.
  • the advantage of the known cooler pipes is that they can be easily manufactured by extrusion or extrusion, and are preferably made from aluminum.
  • the present invention has for its object to produce with simple means and while retaining the advantageous production method of the known tubes such cooler tubes that allow a much better heat exchange; the cooler pipes to be made available should have much better heat exchange properties with the same dimensions.
  • the related manufacturing processes and necessary tools should be simple and enable continuous production of the cooler tubes.
  • the object according to the invention is achieved in that the half webs in the radiator tubes known per se are not straight but are designed in a wave shape in the flow direction.
  • the cooler tubes according to the invention are defined in more detail in claims 1 to 4.
  • the Claims 5 and 6 relate to methods according to the invention by means of which radiator tubes according to claims 1 to 4 can be produced. Devices that are particularly suitable for the previously described methods or cooler tubes are described in claim 7 as inventive.
  • the present invention provides simple means of access to cooler tubes which have significantly improved heat exchange compared to the comparable known cooler tubes because the measures according to the invention impose a quasi-turbulent flow on the media flowing through the cooler tubes. This result is made possible with simple technical means, while at the same time continuous and economical mass production of the cooler tubes according to the invention is possible.
  • Nubs 5 are pressed in on the surface 2 and, preferably, additionally on the opposite lower surface (not shown). Through these knobs 5, the surface 2 is arched in the area of the flow channels for the medium between the continuous walls 3, so that the passage narrows; if this occurs on the two opposite surfaces, considerable constrictions can occur with a corresponding nub depth, through which the quasi-laminal flow in smooth passages is changed to a quasi-turbulent flow.
  • the knobs 5 are preferably attached on both sides of the connecting strip 6 of the cooler tube surface 2 and the half webs 4 such that the half webs are deformed in a wave shape. This also takes place in that the knobs, which are attached on the right and left along the imaginary strip 6, are offset from one another.
  • the resulting corrugation is in terms of its "wavelength" by the longitudinal spacing of the nubs offset from one another and in terms of their "amplitude” by the nub depth. defines the knob diameter.
  • the optimum conditions in this regard can be selected by simple experiments by any average person skilled in the art according to the disclosure of the present teaching according to the cooling tube material and the cooling tube dimensioning.
  • FIG. 2 shows a cross section through a special embodiment of the cooling tube according to the invention Figure 1 again, in this embodiment, the knobs are arranged offset from one another along the imaginary strip 6 according to Figure 1.
  • the special case according to the invention is not shown in terms of features, in which the knobs 5 change the cross section of the throughflow channels between the continuous webs 3 in the knob area, but without causing the corrugation of the half webs 4. But even in this simplest embodiment according to the invention, the embossed knobs considerably disturb the quasi-laminal flow in the previously known comparable cooling tubes.
  • FIG. 1 Another embodiment of the cooling tubes according to the invention is shown in FIG.
  • ribs 7 are required on the top side of the profile for heat exchangers, which are constructed in the same and counterflow principle.
  • the cooling pipe 1 shown corresponds, with the exception of these fins 7, to the embodiments according to the invention according to FIGS. 1 and 2, the reference symbols also having the predetermined meaning here.
  • the ribs 7 are also deformed in a wave shape in such a way that "wavelength” and "amplitude” are precisely defined and completely reproducible.
  • the This is an absolute requirement for the assembly of cooling systems consisting of the cooling pipes according to FIG. 3. The manner in which this embodiment of the cooling tubes according to the invention can be produced is described below.
  • knob roller 8 is mounted in such a way that it acts on the pressed profile while producing the knobs 5 in the cooling tubes according to the invention. This can also be carried out on two sides using two rollers 8, between which the profile passes.
  • the knob roller 8 has knobs 9 which are arranged on the knob roller in mirror image to the knob pattern to be produced on the sleeve 2 of the cooling tubes according to the invention according to FIGS. 1 to 3.
  • the corresponding information applies to the exact positioning of the knobs, their height (or diameter) and the spacing of the adjacent knobs, which can be found in the descriptions of FIGS. 1 to 3.
  • the special embodiment of the cooling tubes according to the invention is produced according to FIG. 3, the corrugation of the ribs 7 being able to be produced by the tool according to FIG. 5, which also fulfills the function of the tool according to FIG. 4. This tool is positioned and used in the same way as described for the knobbed roller according to FIG. 4.
  • This roller tool 10 also has a circumferential groove 11, which serves to receive and bend one of the ribs 7. Step through the extruded profile with the straight ribs 7 these into the undulating grooves 11 and are bent undulating; by choosing a corresponding extent of the roller 10 and / or the number of curvatures of the groove 11 on the circumference of the roller 10, the "wavelength" of the corrugation of the ribs 7 can be defined precisely and reproducibly.
  • the arrangement and mode of operation of the knobs 9 reference is made to the corresponding parts of the description relating to FIG.
