Definitions

  • the invention relates to a collector for a capacitor according to the preamble of claim 1 and a capacitor with a collector according to the preamble of claim 7.
  • the WO 2004/025196 A1 discloses a condenser having a tube-fin block and manifolds disposed on either side of the tube-fin block, the tubes of the tube-fin block engaging through ports of the manifolds and in fluid communication with the interior of the manifolds, parallel to one of the manifolds
  • a collecting manifold is arranged collecting tubes, which is fluidly connected by means of its two overflow via overflow in the manifold to the manifold.
  • the collector is designed according to this document as a one-piece welded tube with soldered lids.
  • the DE 198 48 744 A1 discloses a collector with a short extruded tube piece and a tube piece inserted therein. In this case, a lid is inserted at one end and at the other end a screw plug is screwed.
  • the DE 10 2008 058 808 A1 discloses a collector with a lateral approach for applying the collector to an adjacent header of a condenser, wherein on the approach two overflow for fluid communication of the interior of the collector with the interior of the collecting tube of the condenser are formed.
  • the collector task is accomplished by the features of claim 1, which provides a condenser for a condenser, comprising a tubular wall enclosing an interior, having a closed tube end, and having an open and closable tube end for insertion of an insert into the collector , with a lateral approach for applying the collector to an adjacent header of a condenser, with two overflow openings for fluid communication of the interior of the collector with an interior of the header, wherein the collector is integrally formed.
  • the collector is made of a extruded part.
  • the wall of the collector has a substantially circular segment-shaped region, wherein the lateral projection has a concave region which serves to bear against an adjacent collector tube. Due to the circular segment-shaped contour, a large volume is achieved, whereby a good fit to the adjacent header is achieved by the concave contact area.
  • the lateral projection is subdivided into spaced-apart regions, with an area extending in the axial direction adjacent to the closed tube end and / or an area extending in the axial direction adjacent to the open end.
  • the collector has a region with a recess, wherein the collector in the region of the recess has no contact surface for abutment with the adjacent manifold. This causes the thermal decoupling, since no contact with the manifold in the return area.
  • the collector is formed asymmetrically in horizontal section through the tubular wall with the lateral approach. This has the advantage that the collector can be arranged at an angle to the plane of the capacitor, so that the collector terminates in a plane with the capacitor and does not project forward in the direction of the vehicle front.
  • the tubular wall has an axial region of increased wall thickness at its open tube end.
  • a groove can be introduced, which can serve to receive a securing ring, which can support a plug for closing the open end and axially secure.
  • the overflow openings are formed in the axial region of increased wall thickness and in a subsequent lateral approach to this area.
  • the region of increased wall thickness has a projection on the outer wall of the tubular wall.
  • the axial region of increased wall thickness is an annular region circulating at the pipe end. It may also be expedient if the axial region of increased wall thickness is a c-shaped region which is open at the pipe end and which has no increased wall thickness in the region of the lateral projection.
  • two retaining elements are provided, which are formed protruding from the wall. As a result, a manufacturing step is saved, because the holding element is molded during extrusion.
  • the object of the condenser is achieved with a condenser having a tube-fin block and collecting tubes arranged on both sides of the tube-fin block, the tubes of the tube-fin block engaging through openings of the collecting tubes and in fluid communication with the interior of the collecting tubes , wherein an inventive collector is arranged parallel to one of the manifolds, which is fluidly connected by means of its two overflow via overflow in the manifold to the manifold.
  • FIG. 1 shows a condenser 1 with a tube-fin block 2, wherein on both sides of the tube-fin block 2 manifolds 3 are arranged, the tubes 4 of the tube-fin block 2 by openings 5 of the manifolds 3 sealingly engage and engage with the interior 6 of the manifolds 3 are in fluid communication.
  • FIG. 1 or the FIG. 2 each show only a portion of the capacitor 1, wherein the non-illustrated part has a manifold, as it corresponds to the manifold 3 substantially.
  • a collector 7 Parallel to one of the manifolds 3, a collector 7 is arranged, which has two overflow openings 8, 9, which communicate with overflow openings 10, 11 of the manifold 3, so that the interior 6 of the manifold 3 communicates with an interior 12 of the collector 7.
  • the collector 7 has a tubular wall 13, which encloses an inner space 12.
  • One of the pipe ends 14 of the tubular wall 13 is closed, wherein the other opposite pipe end 15 is formed open and closable.
  • an insert can be used in the collector 7, such as a dry filter insert.
  • the collector 7 on a lateral projection 16, which serves to rest the collector 7 on the adjacent manifold 3.
  • the two overflow openings 8, 9 of the collector 7 are introduced in the region of the lateral projection 16 in the wall of the collector 7.
  • the tubular wall 13 is formed integrally with the lateral projection 16 and the closed tube end 14.
  • the collector 7 is formed in one piece in this configuration by a extruded part, so made of one piece.
  • the lateral projection 16 is integrally formed over the entire axial length of the collector 7 with the collector and thus extends over the entire axial length of the collector.
  • FIGS. 3 and 4 show another example of a capacitor 101 with a collector 107 and a manifold 103, wherein the lateral approach for connecting the collector 107 is formed with the manifold 103 is not continuous along the axial length of the collector.
  • the lateral approach is in the example of FIGS. 3 and 4 formed in two parts and has spaced areas 110, 111, wherein one of these areas 110 is disposed in the axial direction adjacent to the closed tube end 114, wherein the second portion of the lateral projection 111 extends in a region adjacent to the open end 115 of the collector 107th is arranged.
  • a region 112 is provided with a recess 113, wherein it can be seen that the collector 107 in the region 112 of the recess 113 has no contact surface for engagement with the adjacent collector tube 103.
  • the collector 107 thus does not touch the adjacent collecting pipe 103 in the region of the return 113.
  • FIGS. 5 and 6 show further examples of a collector according to the invention 201, 202, wherein the collector 201 is substantially the collector 7 of FIG. 1 corresponds, wherein on the collector 201, two holding elements 203, 204 are mounted, which are advantageously made in one piece with the collector by extrusion.
  • FIG. 6 shows the collector 202, which is essentially the collector 107 of FIG. 3 corresponds, wherein the collector 202 holding elements 205, 206th which are also preferably made jointly by extrusion with the collector.
  • the holding elements 203, 204 205, 206 are produced as a continuous web along the length of the collector and are then freed by mechanical processing such that the areas between the two holding elements 203, 204 205, 206 or above and below the holding elements 203, 204, 205, 206 have been removed by machining.
  • FIGS. 1 to 6 show examples of collectors, which is symmetrical with respect to a median plane which intersects the central longitudinal axis of the collector.
  • the wall of the collector has a substantially circular-segment-shaped region 305, 306, wherein the lateral projection 307, 308 has a concave region 309, 310.
  • the lateral projection 307, 308 thus has a wall which is curved inwards. This advantageously has the effect that, on this concave, inwardly curved region of the wall, the adjacent collecting pipe can be applied flatly.
  • FIGS. 7 to 9 show other variants of collectors 401, 402, 403, similar to the collectors 7 of the FIG. 1 , 107 of the FIG. 3 or 201 of the FIG. 5 are formed, however, the collectors of the FIGS. 7 to 9 are not formed symmetrically in horizontal section.
  • FIG. 12 This is for clarity in FIG. 12 shown in horizontal section. It is in FIG. 12 to recognize that the collector 320 is not formed symmetrically due to the formation of the lateral projection 321.
  • the tubular wall at its open tube end 15 according to FIG. 1 has a region of increased wall thickness 20.
  • the region of the increased wall thickness is effected for example by a projection on the outer wall of the tubular wall 13, wherein the projection is formed only over a portion of the axial extent. It serves to make it possible to install in the region of the projection in the inner surface of the tube a groove into which a securing ring can be inserted for the axial securing of a sealing plug which can be inserted into the opening of the collector.
  • this region of the axial wall thickness may be an annular peripheral region, so that the groove can be worked over the entire circumference.
  • the region of the increased wall thickness at the open tube end can be formed as an open c-shaped region, which does not have an increased wall thickness in the region of the lateral extension. The increased wall thickness would thus be present only in the region which is circular with respect to the cross section of the collector.
