Definitions

  • the invention relates to a collecting tank, in particular a charge-air tank or a coolant tank for a motor vehicle, according to the precharacterizing clause of claim 1 , to a heat exchanger according to the precharacterizing clause of claim 11 and to a method for producing a collecting tank.
  • the tie rod which is formed in one piece with the collecting tank, preferably from plastic, or is at least connected to it in a fixed manner, in particular by means of being molded in, comprises an insert. This is placed into the mold, in particular before the injection-molding. In principle, it is also possible to push the tie rod into openings made during the injection-molding and subsequently seal it, whereby an integral connection is possible, or fasten it by means of a resilient undercut, such as a latching lug for example, whereby a nonpositive connection can be realized.
  • a resilient undercut such as a latching lug for example
  • the insert is preferably a reinforcing element and/or a cooling element.
  • the latter is appropriate in particular in the case of charge-air tanks exposed to high temperatures, since the material temperatures can in this way be specifically lowered in the regions that are subjected to the greatest loading. In this way, the oxidative aging of the plastic is slowed, whereby the service life increases. Furthermore, less expensive plastics can also be used or, in certain cases, the use of plastics instead of aluminum becomes possible in the first place.
  • the insert is preferably a metal insert part, a metal strip, a metal tube, an insert part of fibrous material, a tape of fibrous material and/or a fiber, the fibrous material or the fiber being glass or carbon fibers in particular.
  • An encapsulation with a plastic is preferably provided. This applies in particular to the variant in which the tie rod is pushed in and sealed after the injection-molding.
  • the plastic encapsulation which consists in particular of a plastics material that allows itself to bond without any problem with the plastics material of the collecting tank, makes a very good, preferably integral, connection of the plastics materials possible.
  • the insert is preferaby formed in a hollow manner, in particular with a substantially circular or oval cross section.
  • a number of thin tubes it is also possible for a number of thin tubes to be arranged next to one another, formed separately or in one piece.
  • the insert may consist of a material with good heat conduction, such as copper or aluminum for example. This also applies in particular to the previously mentioned inserts formed in a hollow manner.
  • the insert preferably protrudes outward beyond the outer side of the collecting tank and/or ends in a projection of the collecting tank, in particular in a rib of the same. If the insert ends in a rib or the like, very good anchorage can take place, since, for thermal reasons, the ribs exposed to the ambient temperature have a high modulus of elasticity even during driving operation.
  • a collecting tank according to the invention is used in a heat exchanger, heat exchange tubes opening out into the collecting tank.
  • the heat exchanger has corrugated ribs to increase the size of a heat-exchanging surface, the corrugated ribs being soldered for example to the heat exchange tubes.
  • Such heat exchangers can be used in particular in motor vehicles.
  • the collecting tank according to the invention in any desired heat exchanger on its own or in conjunction with at least one further collecting tank, it being possible for the at least one further collecting tank to be likewise a collecting tank according to the invention or a collecting tank according to the prior art.
  • FIG. 1 shows a heat exchanger with two collecting tanks according to a first exemplary embodiment
  • FIG. 2 shows a section transversely through one of the collecting tanks from FIG. 1 ,
  • FIG. 3 shows a section longitudinally through the collecting tank from FIG. 2 ,
  • FIG. 4 shows a section longitudinally through a collecting tank according to a third exemplary embodiment
  • FIG. 5 shows a section longitudinally through a collecting tank according to a fourth exemplary embodiment.
  • a collecting-tank 1 according to the invention formed as a coolant tank, of an air-conditioning system of a motor vehicle consists of polyamide reinforced with glass fibers, with a tie rod 2 , which comprises an insert of a glass fiber tape.
  • a chemical, exothermally acting blowing agent in granular form is added to a polyamide in granular form, mixed with glass fibers to accelerate the crystallization, the blowing agent being encapsulated with polyethylene, and the granules are mixed with one another and fed to an injection-molding machine.
  • a plastication of the granules takes place in a known way to form a polymer melt as a result of heat (240-290° C.) and pressure.
  • This plastic polymer melt is filled into an injection mold, into which reinforcing elements, in the present case glass fibers arranged in the manner of tapes, which are encapsulated with polyamide, are automatically placed at the locations at which tie rods 2 are intended. In this case, the reinforcing elements are preheated.
  • the blowing agent reacts by emitting thermal energy with the formation of CO 2 .
  • the polymer melt remains in the injection mold until the mold is filled and a certain crystallization and relaxation have taken place. Subsequently, the injection mold is opened, the coolant tank is removed and a clamping frame is immediately inserted to prevent sinking of the coolant tank.
  • the coolant tank has a surface temperature of about 120° C. when it is removed. In this case, the clamping frame may be cooled.
  • a rubber cord seal is placed around an aluminum tank base, the clamping frame is removed from the coolant tank, the coolant tank is placed as quickly as possible, i.e. within about 30-60 seconds, onto the aluminum tank base with the rubber cord seal and pressed in a press.
  • thin metal tubes which are intended for reinforcing and cooling the tie rods, are placed into the injection mold and molded in as inserts for a charge-air tank, the ends of the metal tubes protruding from the mold, so that connection to a coolant circuit is possible later.
  • the coolant cooler is generally arranged near the charge-air tank and therefore only minor changes are required for a charge-air tank that is cooled in a certain region, that is to say in the region of the tie rods.
  • FIG. 4 shows a collecting tank 11 , in the present case a charge-air tank, with a tie rod 12 , which is reinforced by a molded-in tape of aramid fibers as an insert 13 , i.e. the encapsulation of the tape consists of the same material as the collecting tank 11 .
  • the tape is conveyed through the injection mold fully automatically and sheared off before demolding.
  • FIG. 5 Shown in FIG. 5 is the use of a perforated geometry as an insert 23 , in the present case a specially shaped plate of metal, which is completely encapsulated by the material of the collecting tank 21 , as tie rod 22 .
  • a perforated geometry may have elevations, which permit easy clamping in the injection mold.
