Definitions

  • the invention relates firstly to a base plate of a collecting tank for cooling water of a heat exchanger, which along its longitudinal extent juxtaposed passages through which cooling water pipes can be arranged.
  • the invention relates to a heat exchanger for motor vehicles with cooling water pipes and floor plates, which have passages through which the cooling tubes are passed through the floor panels.
  • Such a bottom plate can form a two-part cooling water collection box of a heat exchanger together with an outer panel by the two sheets are pressed together approximately.
  • the bottom plate is in this case the cooling tubes facing part of the cooling water collection box, the cooling tubes protrude through the passages into the cooling water collection box inside.
  • the floor panels contribute significantly to the stability of the cooling water collection boxes and thus also to the stability of an entire heat exchanger, since heat exchangers are usually equipped with two such cooling water collection boxes, namely an inlet cooling water box and a consensuslcühlementkasten. Accordingly, floor panels of the prior art are also well known and available in a wide variety of construction variants.
  • the object of the invention is achieved by a bottom plate of a collecting tank for cooling water of a heat exchanger, which along its longitudinal extent juxtaposed passages through which cooling water pipes can be arranged, wherein the bottom plate is characterized in that arranged between two immediately adjacent passages a reinforcing bead is and that the bottom plate is bent transversely to its longitudinal extent.
  • the combination of reinforcing bead and curved floor panel allows structurally very simple construction to achieve a particularly high rigidity and / or strength of the floor panel without having to use a higher material thickness with respect to the floor panel.
  • the receiving area of the curved floor panel in which the passages are arranged is of particular interest. It is crucial that this receiving area is bent in order to ensure an advantageous stiffening of the present curved floor panel together with the reinforcing beads arranged there.
  • Such a floor panel may advantageously be used in connection with, for example, an outer panel, in particular in two-part header boxes.
  • the bottom plate is the cooling tubes of the heat exchanger in the Turned way that it can be pierced by the cooling tubes.
  • the bottom plate has passages into which the cooling tubes can be inserted.
  • the passages thus form openings in the bottom plate whose inner diameter are ideally matched exactly to the outer diameter of the cooling tubes.
  • the passages are provided in a curved passageway receiving area of the floor panel.
  • cooling box here describes any facilities that can be used as a cooling water inlet device or as a cooling water drain device on a heat exchanger.
  • heat exchanger can be used in a variety of areas, in which heat energy is to be transferred from a first medium to another medium.
  • a main field of application of the heat exchanger described here is in the field of automotive engineering.
  • cooling water covers any liquid coolant that is suitable for absorbing, transporting and releasing heat energy at a suitable location.
  • the bottom plate is bent transversely to its longitudinal extent with an outer radius r with a value between 15 mm and 46 mm.
  • the outer radius r is advantageously dependent on the depth of the floor panel transverse to the longitudinal extent.
  • a radius r of approximately 17 mm advantageously results.
  • the result is advantageously a radius r of approx. 23 mm.
  • a radius r of approximately 30 mm advantageously results.
  • a radius r of about 36 mm With a depth T of the floor of 43 mm to 45 mm, the result is advantageously a radius r of about 36 mm.
  • a radius r of approximately 46 mm With a depth T of the floor of 55 mm to 57 mm, the result is advantageously a radius r of approximately 46 mm.
  • r U / 2 ⁇ holds.
  • U is defined by a fictional circle circumference, which is determined by the curved floor panel. The radius r results from an optimum between a stress at the bottom in the region of the tube end and a stress in the region of the tube center.
  • the bottom plate or the curved passage receiving area can be formed so stiff that in addition to previously required additional reinforcing components, such as tie rods, can be dispensed with. This allows a heat exchanger to build much more compact than conventional heat exchangers.
  • the intended reinforcing bead can be designed diverse.
  • a particularly notable increase in the rigidity of the present floor panel may be achieved when the reinforcement bead is spaced from the passages on the floor panel.
  • the reinforcing bead is not formed in particular by the flanks surrounding the passages, as is customary in the prior art. Rather, elevations or depressions which form a reinforcing bead differ from such flanks.
  • an advantageous embodiment provides that the reinforcing bead is arranged at a distance from a flank bordering the passages on the floor panel.
  • a good increase in the rigidity or strength of the present floor panel is advantageously already achieved by the flank.
  • an additional increase in the rigidity or strength of the present floor panel is achieved in particular by means of the elevations of the reinforcement bead.
  • the reinforcing bead is arranged on the bottom plate independently of a flank bordering the passages, the reinforcing bead can advantageously further increase the rigidity or strength of the present base plate independently of the flank.
  • the stability of the bent floor panel also improves when the flanks of the passages are formed on a first side of the bent floor panel and protrusions of the reinforcement beads on a second side opposite the first side of the curved floor panel.
  • the reinforcement bead may also be arranged differently oriented on the floor panel. If the reinforcement bead is arranged as a transverse reinforcement bead transverse to the longitudinal extension of the floor panel, it stiffens the floor panel substantially transversely to the longitudinal extension. This is particularly advantageous for heat exchangers that build relatively deep.
  • At least one longitudinal reinforcement bead can be arranged between two directly adjacent passages along the longitudinal extension of the floor panel.
  • the floor panel can be additionally stiffened, in particular with regard to its length.
  • the longitudinal reinforcement bead is arranged centrally on the floor panel.
  • the longitudinal reinforcement bead can be made ready.
  • the longitudinal reinforcement bead has a width that occupies more than one third of the bottom plate width.
  • two longitudinal reinforcing beads are arranged on different sides of the bottom plate center axis between two directly adjacent punches.
  • Such a double longitudinal reinforcement bead can likewise achieve an advantageous increase in the rigidity or strength of the present floor panel.
  • the two longitudinal reinforcing beads are arranged on the left and right with an identical distance to the bottom plate central axis, so that the bottom plate can build symmetrical, which can set as far as possible homogeneous rigidity or strength properties on the bottom plate.
  • the longitudinal reinforcement bead may transition into one or more flanks of the passages so as to further increase the rigidity and strength of the floor panel.
  • a correspondingly advantageous embodiment provides that the passages are each surrounded by a flank and two adjacent flanks connected to each other by means of a L Lucassverstärkungssicke are.
  • the object of the invention is also achieved by a heat exchanger for motor vehicles with cooling tubes and floor plates, which have passages through which the cooling tubes are guided through the floor panels, wherein the heat exchanger is characterized by a floor panel according to at least one of the above features.
  • the Indian FIG. 1 shown heat exchanger 1 can be used for example in motor vehicles to cooling water of a. Internal combustion engine (not shown here) to cool.
  • the heat exchanger 1 comprises in this embodiment, a base body 2, on which a cooling water inlet box 3 and a cooling water drain box 4 are arranged.
  • cooling rib shafts 6 are arranged between the individual cooling water pipes 5, extending from the cooling water inlet box 3 to the cooling water drain box 4.
  • Each of the cooling fin shafts 6 provides a plurality of cooling fins 7 on the heat exchanger 1.
  • Both the cooling water inlet box 3 and the cooling water drain box 4 are each composed of a curved bottom plate 9 and a curved outer panel 10 together (numbered here only in terms of the cooling water inlet box 3).
  • Both sheets 9 and 10 are liquid-tightly pressed together at a seam 11 and closed at the top 12 with a first closure 13 and at the bottom 14 with a further closure 15.
  • the cooling water inlet box 3 also has a cooling water inlet 16, while the cooling water drain box 4 has a cooling water outlet 17 in the region of the underside 14.
  • the respective curved bottom plate 9 of the cooling water inlet box 3 and the cooling water drain box 4 is arranged relative to the individual cooling water pipes 5 such that the cooling water pipes 5 are aligned substantially at a right angle 18 to the longitudinal extension 19.
  • cooling water inlet 16 and the cooling water outlet 17 are respectively provided on the corresponding outer panel 10, communicate the cooling water pipes 5 with the respective curved bottom plate 9 of the cooling water inlet box 3 and thedeementablauflcastens 4 by piercing passages 20 of the curved bottom plate 9.
  • Embodiments for advantageously designed floor panels 9 are in the FIGS. 2 to 8 shown.
  • the same or equivalent components or groups of components for the sake of simplicity may be identified by the same reference numerals.
  • first embodiment 25 illustrates a curved bottom plate 9, which is substantially U-shaped and terminates at its side regions with a first leg 26 and a second leg 27.
  • the two legs 26 and 27 are substantially parallel to each other.
  • a curved passage receiving portion 28 having a radius r along the longitudinal extent 19 of the curved bottom plate 9, in which the passages 20 are arranged.
  • FIG. 3 After FIG. 3 are two directly juxtaposed passages 29 and 30 are clearly visible, which are each formed transversely to the longitudinal extent 19 and along a bottom plate center axis 31 are arranged side by side.
  • the first passage 29 is substantially surrounded by a first flank 32, while the second passage 30 is substantially surrounded by a second flank 33.
  • the two flanks 32, 33 are formed as elevations 34, which rise on a concave side 35 of the bent through-receiving region 28 or of the curved bottom plate 9.
  • a longitudinal reinforcement bead 36 (see FIG. 3 ), which extends along the longitudinal extent 19 of the curved bottom plate 9 on the bottom plate central axis 31.
  • the longitudinal reinforcement bead 36 is placed between two immediately adjacent passages 20 and 29 and 30, respectively.
  • the curved base plate 9 thus undergoes an additional stiffening, in particular along its base plate central axis 31.
  • another embodiment 40 comprises an alternatively designed bottom plate 9 two longitudinal reinforcing beads 41 and 42, which are located in the longitudinal extent 19 in addition to a bottom plate center axis 31.
  • the first longitudinal reinforcing bead 41 is arranged on a first side 43 next to the base plate center axis 31 and the second longitudinal reinforcing bead 42 is arranged on a second side 44 next to the bottom plate center axis 31.

  • a bent floor panel 9 of another embodiment 50 (see FIGS. 7 and 8 ) has a transverse reinforcement bead 51 between two immediately adjacent passages 29 and 30.
  • the transverse reinforcement bead 51 runs essentially transversely to the longitudinal extent 19 of the curved bottom plate 9 in the direction of the two passages 29 and 30 and thus extends between two legs 26 and 27 of the curved bottom plate 9.
  • the transverse reinforcement bead 51 is arranged at a distance from the flanks 32, 33 bordering the passages 29, 30 and in the region of the curved passage receiving area 28.
