Definitions

  • the invention relates to a cooler with modular composable Radiator components, consisting of coolant tubes, Slats and discs.
  • the invention also relates to a Method for producing such a cooler.
  • Coolers are generally used to cool fluids, e.g. Cooling water, engine or transmission oils, air, e.g. Charge air, Refrigerants, etc. and as stationary or mobile units used. Such coolers usually have two each other opposite water boxes on, in the tube sheets Openings are provided, in which the ends of the Coolant tubes are inserted. Between Coolant tubes are the cooling fins, e.g. Corrugated ribs, through which the heat to the passing air is delivered. Such coolers are usually made several materials, e.g. Aluminum for the coolant pipes and the slats and plastic for the water boxes. Under Circumstances, the cooler still have nonferrous metal connections or other elements. In any case, owns such Cooler a given structure by e.g. the openings in the Tube bottom usually regular and given Positions are provided. Such coolers are for certain applications in their performance optimized or on coordinated specific installation conditions.
  • Modular coolers are e.g. from DE-A-196 05 340 known. These coolers have a number of advantages, but must be provided with connections. From the FR-A-2 625 301 is a cooler with an orthogonal Connection channel known in which the connection channel over a variety of discs extends. The medium to be cooled is guided in sandwiched elements, the one Ceiling, have a bottom and a peripheral edge. To Formation of the connection channel and sandwiched Elements are needed so many different slices and many additional components.
  • the invention is based on the object, a radiator to provide, on the one hand of a small number different components is constructed, on the other hand relative fast both at a changed performance profile and at can be adapted to another space.
  • a task of The invention is also the provision of a method for Production of such a cooler.
  • the cooler according to the invention has a small number different components, namely only flat tubes, on the flat tubes sitting discs and between the discs arranged, also sitting on the flat tubes Lamellae.
  • the discs and the slats in one Level the same height, and in the next level can the Height of the slices or slats should be larger or smaller.
  • the height the cooler of the number of stacked Flat tubes, slats and discs depends, and the width as well as depth of the radiator from the dimensions of the components depends.
  • the number and packing density of the flat tubes hangs So no longer from the positions of the receiving openings in a tube bottom of the channel box, but can be customized to get voted.
  • the size of the invention Radiator the given requirements without further notice Selection of the corresponding components to be adjusted.
  • a disc as a connection piece formed and has a breakthrough orthogonal Connection channel on. About the breakthrough become the individual Flat tubes supplied with the medium to be cooled, the Medium via the connection channel in the connection piece initiated or discharged from this.
  • the cooler according to the invention can be used both as a coolant cooler, as intercooler, as oil cooler, in monobloc design, as Combi cooler and simply designed in side-by-side variants become.
  • In a single cooler can also different air lamellae are used. For different benefits are different block depths, e.g. 75 mm, 120 mm or 150 mm possible.
  • the use of Repeat parts allows the cost-effective construction and the Reduction of storage costs.

  • the disc has at least the height, the total height of two slats with one in between arranged flat tube or flat material corresponds.
  • Such discs are e.g. required even if the Connection channel has a relatively large diameter and therefore not in a normal disc is accommodate.
  • Larger height slices are usually two slices summarized, with the flat tube not on the flat side the disc rests but in a breakthrough orthogonal slot is inserted. The flat tube is open at the front and the slot is with the opening connected. The flat tube becomes fluid-tight in this slot soldered and thereby connected to the supply channel.
  • the disc has two or more, adjacent breakthroughs and two or more flat tubes side by side on this Disc are arranged. This will be the opportunity created that in a single cooler multiple media be cooled simultaneously, the flat tubes only are connected to each other via the discs. This exists the possibility that each flat tube has its own slats or that the flat tubes over a common lamella additionally connected to each other.
  • Coolers for two or more media to be cooled can do so be designed that liquids and / or gases are coolable at the same time.
  • the width and / or the depth of the radiator on the Height vary.
  • the shape of the cooler can be this way optimally adapted to the local conditions.
  • the invention also relates to the process for the preparation a cooler, the flat tube, discs, fins and If necessary, cassettes are first cassetted in a cassette and then in a brazing furnace, the components be soldered together to the finished radiator. After the soldering process, there is no need for any rework on the radiator which, on the one hand, has the advantage of increasing the production effort a minimum is reduced, and that eventual, at a Reworking resulting contamination can be avoided.
