Definitions

  • the invention relates to a heat exchanger for a motor vehicle, comprising a heat transfer block and at least one collecting box with a tubesheet, wherein the heat transfer block is formed from a plurality of mutually adjacent tubes and interposed corrugated fin elements, and the tubes with one of its end portions in the tube sheet of the fluid-tight Collection box are included. Moreover, the invention relates to a method for producing a heat exchanger.
  • heat exchangers are used for cooling or for heating fluids, by means of which a heat transfer between a first fluid and a second fluid is caused.
  • the tubes, corrugated fin members, and tube sheets are made of a metallic material in some known embodiments.
  • the lid-like elements are made either of a metallic material, such as aluminum, or of a plastic.
  • a disadvantage of the known in the art heat exchangers is in particular that due to the large number of variants tubes with different geometries are used, the tubes are arranged at different distances from each other and the number of tubes used also varies. Therefore, it is difficult to use modular components for the production of heat exchangers, whereby the production of the heat exchanger is complex and expensive.
  • heat exchangers are further known, which have a collecting box, which is formed of plastic and molded directly onto the tubes and the corrugated fin elements.
  • a heat exchanger is from the US 5865244 known, which also discloses the heat exchanger according to the preamble of claim 1.
  • a disadvantage of the known heat exchangers with a molded collection box is in particular that the heat transfer block formed from tubes and corrugated fin elements is not sufficiently protected against contact with plastic during the injection process. Also, the sensitive corrugated fin elements are not sufficiently protected against the pressures arising during the injection process, so that damage to the corrugated rib elements in particular can occur.
  • the heat exchanger with a molded collection box therefore often have only a very small number of tubes, whereby the performance of the heat exchanger is severely limited.
  • An embodiment of the invention relates to a heat exchanger for a motor vehicle, with a heat transfer block and at least one collecting box with a tube bottom, wherein the heat transfer block is formed of a plurality of mutually adjacent tubes and interposed corrugated fin elements, and the tubes with one of its end portions in fluid-tight the tubesheet of the header tank are received, wherein the tubesheet of the header tank is formed of plastic and injected onto the heat transfer block by injection molding, wherein between the collecting box and the heat transfer block, a spacer element is arranged, through which the tubes are passed, wherein the corrugated fin elements through the spacer element are spaced from the tube bottom of the header tank.
  • the tubes and corrugated fin members are bonded together from a metallic material and by a brazing process or a welding process.
  • the tubes and the corrugated fin elements may also be held by a tooling device until sufficient molding is produced between the elements by injection of the tube bottom of the collection box.
  • the heat exchanger may have only one collecting box or, in an alternative embodiment, two collecting boxes.
  • the tubes may either be accommodated in the end thereof, while the respective other end-side region is accommodated in another structure, or the tubes may be U-shaped, for example, so that the tubes are respectively received in both end-side regions in the one collecting box.
  • the tube plate of the collecting box is advantageously made of plastic and molded onto the heat transfer block by injection molding. This is particularly advantageous, since the tube plate of the collecting tank can be generated quickly and easily and in particular can be easily adapted to different heat exchangers. For this purpose, only the mold for the production of the molded tube bottom of the header box must be adjusted. The tube plate of the collecting box or the collecting box or the heat exchanger can therefore be produced in a simple manner in a high variety of variants.
  • a spacer element is arranged between the heat transfer block and the tubesheet of the header tank. This mainly fulfills a separation function and a protective function.
  • the spacer element is advantageously prevented that the plastic of the tube plate of the collecting tank penetrates between the corrugated fin elements and this damaged.
  • the heat transfer block is protected by the spacer from the high pressures that may arise during injection molding of the plastic and in particular could damage the partially thin-walled tubes and also very thin-walled corrugated fin elements.
  • the spacer element is formed by a perforated plate, which has recesses which correspond with the tubes in the heat transfer block such that they project precisely through the recesses.
  • a design of the spacer element as a perforated plate is particularly advantageous because in this way on the one hand, the tubes can be performed with one of its end portions through the spacer element, while the corrugated fin elements are otherwise covered by the spacer element. This can easily the collection box be injected onto the heat transfer block, without damaging the corrugated fin elements.
  • the recesses of the spacer element are preferably formed with only a small clearance relative to the tubes in order to allow the most accurate fit of the tubes in the spacer element. This is particularly advantageous in order to prevent plastic from penetrating between the tubes and the recesses during the injection molding of the tube bottom of the collecting box, as a result of which the corrugated rib elements are damaged.
  • the tubesheet of the header tank is molded onto the heat transfer block with a plastic injection molding process.
  • a plastic injection molding process is particularly advantageous for the production of the tube bottom of the collecting box, since on the one hand it allows a high freedom of shaping and on the other hand enables the production of a collecting box with a sufficiently high compressive strength.
  • the tubes have an at least partially circumferential notch at the end and / or are roughened on the end side.
  • An at least partially circumferential notch and / or a surface-pretreated and / or coated, such as roughened, end region are advantageous in order to produce a better connection between the tubes and the molded tube bottom of the collecting box.
  • the notch may form an edge which is engaged behind by a portion of the tube bottom of the header, whereby the connection is improved.
  • the heat exchanger has two manifolds, wherein the tubes each end in one of the manifolds and fluid-tight are connected thereto, wherein between each of the collecting tanks and the heat transfer block, a spacer element is arranged.
  • a heat exchanger with two opposing manifolds, which are fluidly interconnected by the tubes of the heat transfer block.
  • the heat exchanger can be flowed through conventionally from a collecting tank through the pipes to the opposite collection box.
  • a simple or multiple deflection of the fluid flowing through the heat exchanger can be achieved in this way, whereby different skillsströmungskosien can be generated.
  • the different flow-through principles essentially correspond to the flow-through principles of the heat exchangers of conventional design.
  • the spacer element is overmolded on the side facing away from the heat transfer block with plastic, which forms the tube plate of the collecting box, wherein the tubes are materially and / or positively connected to the molded tube plate of the collecting box.
  • the collecting box is bounded on all sides by the molded plastic.
  • the spacer element is not fluid-tightly connected to the tubes.
  • the spacer thus forms a surface to which the tube sheet of the header tank is molded.
  • the tubesheet of the collection box is preferably connected to the projecting through the spacer tube sections, whereby the tubesheet of the header is connected directly to the heat transfer block and the tubes are fluid-tightly connected to the tube bottom of the header box.
  • the tubes and / or the tube bottom of the collecting tank can be generated a cohesive and / or positive connection between the tubes and the tube sheet of the header box.
  • the spacer element forms a reinforcement of the heat transfer block facing bottom region of the header tank, wherein the spacer element is positively and / or materially connected to the collection box.
  • the spacer element which may for example be formed of a metallic material, form a reinforcement of the heat transfer block facing bottom region of the collecting tank. This increases the stability of the collecting tank and thus also the durability of the heat exchanger.
  • the spacer element can have, for example, shoulders, edges or roughened areas which improve the connection between the plastic of the collecting tank and the spacer element.
  • the spacer element is soldered to the tubes and / or the corrugated fin elements and / or welded and / or jammed and / or glued. Depending on the choice of material of the spacer element this can be connected to the tubes and / or the corrugated fin elements, whereby the overall strength of the heat exchanger can be increased.
  • An embodiment of the invention relates to a method for producing a heat exchanger, wherein a heat transfer block is produced from a plurality of mutually adjacent tubes and interposed corrugated fin elements, wherein the tubes end a spacer is placed and the tube sheet of the header to the heat transfer block and / or Distance element is molded in one piece.
  • the heat transfer block may preferably be produced in a conventional manner by, for example, soldering the tubes to the corrugated fin elements. It is thus produced an independent component, which specifically processes further can be.
  • the placement of the spacer element is advantageous in order to prevent damage to the corrugated rib elements due to plastic components occurring during the subsequent injection molding of the tube bottom of the collecting tank.
  • the tube plate of the collecting tank is advantageously injection-molded onto the heat transfer block in such a way that a fluid-tight and pressure-tight connection is produced between the tube ends projecting through the spacer element and the interior of the molded tube bottom of the collecting box.
  • the tubes penetrate the spacer element by means of shaped, precisely fitting recesses and the corrugated rib elements are completely covered by the spacer element. This is particularly advantageous in order to achieve a play-free as possible seat of the spacer element on the heat transfer block and to avoid the injection of plastic in the filled by the corrugated fins area.
  • the tube plate of the collecting box is molded onto the tubes projecting through the spacer element, wherein the tube plate of the collecting box is connected to the projecting sections of the tubes and / or the spacer element materially and / or positively.
  • the collecting box is formed or closed by connecting a tube bottom of the collecting box with a cover of the collecting box.
  • the tubesheet and the lid can be made separately and connected to each other or they can be made together by injection molding.
  • the FIG. 1 shows a sectional view through a heat exchanger 1.
  • the heat exchanger 1 has a heat transfer block 7, which is formed by a plurality of tubes 2 and arranged therebetween corrugated fin elements 3.
  • the heat transfer block 7 is of conventional design, wherein the tubes 2 are arranged parallel to each other and spaced from each other. In the spaces between the tubes 2, the corrugated fin elements 3 are arranged and are in thermally conductive contact with the tubes. 2
  • the tubes 2 have a longer extension than the corrugated fin elements 3, therefore the corrugated fin elements 3 are laterally out of the heat transfer block 7.
  • a spacer element 4 is placed, which has a plurality of recesses 6.
  • the tubes 2 protrude through the recesses 6.
  • the cross sections of the recesses 6 are adapted to the cross sections of the tubes 2, whereby a play-free fit of the spacer element 4 is achieved on the tubes 2.
  • the spacer element 4 or the recesses 6 is / are adapted to the arrangement of the tubes 2 within the heat transfer block 7.
  • a collecting box 5 is connected to a tube plate 8, which is produced by a spraying process.
  • the tube plate 8 of the header 5 is molded directly onto the heat transfer block 7.
  • the tube plate 8 of the header 5 is injected around the projecting through the spacer 4 sections of the tubes 2, whereby depending on the design of the tubes 2, a positive and / or cohesive connection is generated.
  • the spacer 4 may also be completely or partially encapsulated by the plastic of the tube plate 8 of the header 5, whereby also a positive and / or cohesive connection is generated.
  • the spacer element 4 can either be attached only to the tubes 2 of the heat transfer block or be connected to the tubes 2 and / or the corrugated rib elements 3. This can be achieved, inter alia, by conventional joining methods, such as welding or soldering.
  • the main task of the spacer element 4 is to prevent plastic from penetrating into the region of the corrugated fin elements 3 during the injection process, in which the collecting box 5 or the tube plate 8 of the collecting box 5 is formed, where it causes damage or clogging of the corrugated fin elements 3.
  • these are joined together with a lid to the collection box 5.
  • the collecting box 5 is in FIG. 1 shown as a cuboid body, which receives the end regions of the tubes 2 of the heat transfer block 7.
  • the tube sheet 8 of the collecting tank 5 and also the collection box 5 take other forms.
  • the shape of the tube plate 8 and the collecting box 5 is to be adapted to the intended use.
  • the collecting box 5 may be formed inside by a single section or divided into several sections by partitions, which are co-produced during the injection process.
  • a change in the shape of the collecting box 5 and / or the tube bottom 8 can be achieved by a simple influencing of the tool used for spraying the plastic.
  • a suitable tool and the spacer element 4 By using a suitable tool and the spacer element 4, a functional heat exchanger 1 can be generated, which can be generated in particular without damaging the heat transfer block 7 with the best possible utilization of the available installation space, in particular in the region of the heat transfer block 7.
  • complex sealing work and additional sealing elements are not necessary, since the tube sheet 8 of the collecting tank 5 is integrally formed.
  • the FIG. 2 shows a plan view of a spacer element 4.
  • the spacer element 4 has a rectangular plate-like shape.
  • a plurality of recesses 6 are arranged, which serve for passing through the end portions of the tubes 2.
