Definitions

  • the invention relates to a heat exchanger, in particular for motor vehicles for a first and a second flow medium, in particular according to the preamble of claim 1.
  • this temperature threshold up to about 260 to 270 degrees Celsius, aluminum manifolds are used for intercoolers, which are more temperature-resistant. If you want to continue to use these conventional charge air cooler, ie at increased boost pressures and charge air temperatures, you need a pre-cooler, ie the charge air is cooled down in two stages, to preferably less than about 260 degrees through the precooler. This must therefore be particularly temperature resistant.
  • the charge air is cooled in the intercooler of motor vehicles usually by ambient air, wherein the intercooler is arranged in the front engine compartment of the motor vehicle in the region of a coolant / air cooler.
  • the coolant of the cooling circuit of the internal combustion engine cools the charge air.
  • a disadvantage of known charge air coolers is the deflection of the charge air in the air boxes, which leads to a pressure drop.
  • Other constructions, z. B. plate or stacked disk heat exchanger according to DE-A 195 11 991 have due to the double 90 degree deflection of the charge air on an increased pressure loss.
  • the tube bundle and one of the two tubesheets are integrally formed and produced by the extrusion molding method known per se.
  • Extrusion molding is a known technology, similar to extrusion and extrusion, with a blank being forced through a forming die (see FIG. Dubbel, paperback for mechanical engineering, 20th edition, S30).
  • the material used is preferably an aluminum extrusion alloy which is particularly suitable for extrusion.
  • the product thus produced by extrusion is a finished tube sheet, to which all tubes of the tube bundle connect seamlessly and in one piece.
  • the remaining parts such as the second tube sheet, the housing and the connecting pieces are made of aluminum materials and are conventionally connected to the extrusion, z. B. by soldering or welding. It is also advantageous that any pipe cross section, be it produced in round or square shape by the extrusion. It is also advantageous that the tubes of the tube bundle can be produced in any length and wall thickness. The temperature resistance is also achieved by a low-stress geometry of the Ganzaluminium Anlagenübertragers invention.
  • the housing is produced by extrusion, d. H. in one operation with the tubesheet and the tube bundle.
  • the transition region between the tubes and the tubesheets is designed round, ie provided with a radius.
  • the transition radius is preferably arranged on the tube outer side, but can also be provided in the inflow region of the tube on the tube plate. The latter would further reduce the primary-side pressure drop.
  • the heat exchanger according to the invention is used as a charge air cooler for internal combustion engines of motor vehicles, as a pre or intercooler of a charging system.
  • a charge air cooler for internal combustion engines of motor vehicles as a pre or intercooler of a charging system.
  • Fig. 1 shows in exploded view a charge air cooler 1 for an internal combustion engine, not shown, of a motor vehicle.
  • the intercooler 1 consists of the following parts, from left to right in the drawing: an inlet nozzle 2, a tube bundle 3 with tube sheet 4, designed as a housing shell, cylindrical housing 5 and an outlet nozzle 6.
  • the tube bundle 3 consists of a plurality of tubes 3a , which are formed integrally with the tube sheet 4 and each having a rectangular flow cross-section 3b.
  • the tubesheet 4 and the adjoining tubes 3a are made by extrusion, ie, a process similar to extruding or extrusion molding.
  • the starting material used is an aluminum extruded alloy, which is pressed by a die, not shown, with the geometry and the arrangement of the tubes 3a.
  • the cross section of the tubes 3a and their length and wall thickness can be freely selected by the extrusion process or the corresponding die.
  • the tubes 3a are thus firmly and tightly connected to the tubesheet 4 and require no post-treatment in principle.
  • the tube bundle 3 has a side facing away from the tube bottom 4 end face 3c, which is provided in a conventional manner with a second tube plate, not shown. All parts, preferably made of aluminum alloys exist are soldered together to form a complete heat exchanger.
  • the housing shell 5 has on its circumference an inlet nozzle 7 and this diagonally opposite to an outlet nozzle 8 - thus, a cooling chamber 9 is formed between the two tube sheets and the housing shell 5, which can be flowed through by the coolant of a non-illustrated cooling circuit of the internal combustion engine.
  • the coolant thus flows between the tubes 3a and around the tube bundle 3.
  • the hot charge air represented by an arrow LL, enters into the inlet connection 2, which is designed in the manner of a diffuser and thus distributes the charge air evenly to the surface of the tube bottom 4 and the individual tube cross-sections 3b.
  • the charge air flows through all the tubes 3a of the tube bundle 3 and exits on the opposite side 3c from the tube bundle 3 and into the outlet nozzle 6.
  • the fully assembled intercooler 1 is inserted into a charge air line, not shown, which is flush with the inlet nozzle 2 and the outlet nozzle 6.
  • the intercooler 1 is thus rectilinear, ie flows through the charge air without deflections, which has a low pressure loss result.
  • Fig. 2 shows a further embodiment of the invention, namely a charge air cooler 10 with a housing 11 which is integrally formed with a tubesheet 12 by extrusion, with the tubesheet 12, a non-visible tube bundle, represented by a dashed tube 13, integrally formed and also by extrusion is made.
  • a non-visible tube bundle represented by a dashed tube 13
  • three components or assemblies namely tube bundle, tubesheet and housing in one step by extrusion are made in one piece.
  • a conventionally manufactured tube sheet 14 is placed, which is connected to both the tubes 13 and the housing 14 and thus forms a cooling chamber for the coolant within the housing 11.
  • an inlet nozzle 15 and an outlet nozzle 16 are used, which are connected to the housing shell 11. All parts are made of aluminum alloys and are preferably soldered together.
  • the intercooler 1, 10 according to Fig. 1 and Fig. 2 are preferably used as pre-cooler or intercooler in a charging system for an internal combustion engine. Both intercoolers are all-aluminum radiators and thus withstand charge air temperatures of up to more than 300 degrees Celsius, which is also achieved by a voltage-optimized design. In the case of pre-cooling, the charge air is pre-cooled to about 260 degrees and can then be fed to a conventional intercooler for further cooling.
