Definitions

  • the invention relates to a tube plate of a heat exchanger according to the preamble of claim 1 and a heat exchanger, in particular for motor vehicles according to the preamble of claim 10.
  • Heat exchangers for motor vehicles are known in various designs, eg. B. as soldered whole aluminum heat exchanger or as a mechanically joined systems in which the individual parts of the heat exchanger are not material, but mechanically interconnected.
  • circular tube heat exchangers in which the pipe ends are connected by mechanical expansion with passages of a tube plate are mechanically joined.
  • Such a round tube heat exchanger for use as a coolant radiator for motor vehicles for example, by the EP 0 406 774 A1 known.
  • the tube sheet of mechanically joined systems is mechanically connected to a collecting box made of plastic, a so-called water tank, with the interposition of a rubber seal.
  • the metallic tube sheet which is preferably made of an aluminum alloy, by beading.
  • a mechanically joined heat exchanger for motor vehicles with a metallic tube sheet was known, which is reinforced by extending transversely to the tube sheet beads.
  • the tubesheet has a flat plate, in which passages, also called collar, and between the passages, the beads are formed.
  • the plate of the tubesheet is bordered by a circumferential groove, which serves to receive a sealing bead for sealing a water box.
  • corrugations are arranged in the edge region of the tube plate between the passages, which are preferably rectangular in shape and embossed into the tubesheet.
  • the beads are formed by three approximately U-shaped side walls and an open to the groove of the tube sheet side, ie the beads go directly into the gutter.
  • the arrangement of the beads thus extends over each the entire length of the two longitudinal sides of the tubesheet.
  • the bead according to the invention is relatively easy to produce by a corresponding Umform réelleddling and therefore cost.
  • the tubesheet and the heat exchanger are thus not burdened with additional costs.
  • the wall thickness of the tubesheet can be reduced due to the beads, thereby saving weight - an advantage that is particularly important when used as a heat exchanger in motor vehicles of particular importance.
  • elongated beads are embossed in the tubesheet, which extend between the passages, depending on the pattern of the passages either transversely or obliquely to the longitudinal direction of the tube sheet.
  • the tube sheet is advantageously used in heat exchangers for motor vehicles, in particular in radiators or coolant radiators, which are both flowed through by the coolant of the coolant circuit of the internal combustion engine and are thus exposed to similar loads.
  • Fig. 1 shows a perspective view of a tube sheet 1, as it is mechanically joined heat exchanger, z. B. radiator ordeffenkühlem used in motor vehicles.
  • the tube sheet 1 is made of a sheet metal plate, preferably made of an aluminum material and has an inner part in the form of a rectangular plate 2 and an outer, the plate 2 enclosing area in the form of a circumferential groove 3.
  • passages 4 are arranged for receiving pipes, not shown, of the heat exchanger.
  • the passages 4 are made by punching punching.
  • the tubes, not shown, so-called round tubes are connected by mechanical expansion of the pipe ends with the passages.
  • elongated beads 5 for stiffening the central region, ie the plate 2 is formed.
  • rectangular-shaped beads 6 are each arranged between adjacent passages, which are also embossed in the tube sheet 1.
  • the tubesheet 1 has two longitudinal sides 1 a, 1 b and two narrow sides 1 c, 1 d.
  • the rectangular beads 6 are arranged on the entire length of the longitudinal sides 1 a, 1 b, in each case between two passages 4. This results in a stiffening of the tube plate 1 and the plate 2 in the edge regions, by an increase in the resistance moment.
  • Fig. 2 shows a plan view of the tube sheet 1 according to Fig. 1 , the same reference numbers are used for the same parts.
  • the beads 6 are approximately rectangular in plan view, formed approximately square and have three U-shaped side walls arranged 6a, 6b, 6c and an open side 6d. Between the side walls 6a, 6b, 6c, a bead bottom 6e is arranged. The side walls 6a, 6c approach approximately to the adjacent passages 4 zoom. The open side 6d passes over the bead bottom 6e directly into the circumferential groove 3.
  • the obliquely extending oblong beads 5 each end in front of the rectangular beads 6.
  • Fig. 3 shows a longitudinal section through the tube sheet 1 in the sectional plane III-III in Fig. 2 , In this sectional view, the depth of the expression of the beads 6, the bead bottom 6d and the two side walls 6a, 6c can be seen. The depth of the expression with respect to the plate 2 determines the moment of resistance of the tube bottom in this edge region.
  • Fig. 4 shows a cross section through the tube sheet 1 in the sectional plane IV-IV in Fig. 2 , It can be seen that the bead bottom 6d merges directly into the channel 3, ie the bead 6 is open towards the channel 3.
  • the bead wall 6b merges into the plate 2, to which an adjacent passage 4 connects.
  • the depth of the bead 6 corresponds in the illustrated embodiment, the height of the passage 4.
  • the beads 6 - depending on the stresses occurring - be pronounced different degrees to achieve a corresponding moment of resistance.
  • the tube sheet 1 which is not shown, but is known from the aforementioned prior art, on the one hand connected to a water tank made of plastic and the other with pipes of a tube bundle.
  • a rubber seal is inserted, which is clamped by means of a flared connection with respect to the water tank.
  • the tube ends of the tube bundle are preferably expanded mechanically directly against the passages. Alternatively it can be arranged between the pipe ends and the passages, a rubber seal.
  • Such a mechanically joined heat exchanger can be advantageously used as a radiator or coolant radiator for motor vehicles.
