Definitions

  • the invention relates to a heat exchanger, in particular a charge air cooler for motor vehicles according to the preamble of claim 1.
  • Intercooler and coolant radiator are made of aluminum (aluminum alloys) and soldered, either only the heat exchanger block or the entire heat exchanger including manifolds.
  • the heat exchanger block, especially in intercoolers is constructed from a series of flat tubes, between which corrugated fins are arranged.
  • the tube ends of the flat tubes are received in openings, so-called passages of the tubesheet and are soldered to the passages. This creates a solid and tight pipe / floor connection.
  • the collection boxes are soldered or welded to the tubes.
  • the tube plate has a peripheral edge strip, which extends over or under the collecting box and thus forms a soldering surface.
  • the passages in the tube sheet extend over its entire depth, ie from longitudinal side to longitudinal side, wherein between the narrow sides of the passages and the edge strips a transition region exists, the trough-like, z. B. is formed approximately U-shaped.
  • the tube sheet thus has an approximately rectangular-shaped, possibly circumferential groove, which is composed of two parallel longitudinal and two parallel narrow sides.
  • the long sides of the tube bottom are opposite to the narrow sides of the passages.
  • the headers are characterized by the internal pressure of the heat transfer medium, z. B. charged charge air.
  • the pipe / floor connection is claimed on its narrow side and in the pipes corner areas by these stresses and deformations so that it can lead to leaks in the heat exchanger.
  • EP 791 797 A is a heat exchanger described according to the preamble of patent claim 1.
  • a reinforcement is provided in the transition region of the tubesheet.
  • the tubesheet which has approximately the same wall thickness in the remaining area due to its production from a sheet metal blank, is therefore less deformable on the longitudinal sides in the region of the narrow sides of the tube. This will be the Pipe / soil connection less or hardly on bending, but essentially stressed on thrust, which is a much cheaper load.
  • the reinforcement is designed as an inserted profiled strip which at least partially fills the channel-like transitional area and conforms to narrow sides of the passages, and is preferably soldered to the tube sheet.
  • This profile strip gain is achieved, through an additional part, which is connected to the tubesheet to a rigid area.
  • a connection ie a fixed bridge is provided which prevents deflection or deformation of the transition region.
  • the profile strip is designed as a (separate) Einlege advisor, d. H. an additional part, which is inserted into the channel-like transition region and soldered to the tube bottom.
  • Einlege advisorn can be used for heat exchangers, especially intercooler, which are to be used for higher charge air pressures.
  • intercooler which are to be used for higher charge air pressures.
  • the same cooler can be adapted to the higher operating stresses with this simple, targeted measure.
  • the corner regions of the tubes are protected from harmful voltage spikes.
  • Fig. 1 shows a section, ie a "disc” of a charge air cooler in the area of the charge air box and the pipe / floor connection.
  • Such intercoolers are used for the cooling of compressed charge air in motor vehicles, especially commercial vehicles.
  • a collection box 1 (also called charge air box) is formed in cross-section U-shaped and preferably made of an aluminum alloy. Overall, the collection box 1 in the form of an elongated box, which can be made by deep drawing or casting.
  • the U-profile of the header tank 1 has two legs 2, 3, which form the longitudinal sides of the charge air box.
  • the collecting tank 1 is inserted into a tube plate 4, the longitudinal side edges 5, 6, which are angled approximately perpendicular to a bottom plate 7.
  • the bottom plate 7 has a plurality of passages, of which only a passage 8 is shown here, which receives a pipe end 9a of a flat tube 9.
  • the entire heat transfer or intercooler thus has a plurality of flat tubes, between which corrugated fins, not shown, are arranged, which form secondary heat exchange surfaces for ambient air.
  • the legs 2, 3 of the box profile have at their lower, ie open side connecting portions 2a, 3a, which overlap with the edge strips 5, 6 of the tube plate 4 and are soldered together in this area. Below the lower edges of the connecting portions 2a, 3a are shown hatched, so-called Einlege advisorn 10, 11 are arranged.
  • Fig. 2 shows the collection box 1 according to Fig. 1 as a view, ie in a sectional plane before the passage 8.
  • the tube sheet 4 is - as known from the prior art - made of a sheet metal blank and therefore essentially has a constant wall thickness s; the passages 8 are directed inwards, ie towards the side of the box 1.
  • the tubes 9 are with their tube ends 9a inwardly beyond the passage 8 addition.
  • the passages directed to the outside.
  • the tubes can project beyond a tube bottom surface or advantageously end below such a tube bottom surface.
  • the flat bottom plate 7 is on the longitudinal sides of the tube sheet 4, d. H. outside of the passages 8, but within the edge strips 5, 6 channel-like design, said groove passes on the one hand in the bottom plate 7 and on the other hand, in the edge strips 5, 6, d. H. Transition areas 12, 13 forms. Due to the loading of the box 1 by the internal pressure caused by the compressed charge air, pressure and / or tensile forces develop in the longitudinal sides 2, 3 of the box 1, which are transmitted to the edge strips 5, 6 of the soil and in the transition regions 12, 13 cause bending stresses and deformations.
  • the invention by the arrangement of the Einlegemannn 10, 11, which are designed as profile strips and have a profile which corresponds to that of the transition regions 12, 13.
  • the Einlegeorn 10, 11 are thus outside of the edge strips 5, 6, down to the channel-like transitional areas 12, 13 and inside of the narrow sides of the passages 8 at. Above the edge strips 10, 11 air gaps 14, 15 are left.
  • Fig. 3 shows a sectional view in a plane parallel to the plane according to Fig. 2 ,
  • the passages 8 are clearly visible in their profile: the passages 8 form with the outer wall of the tube 9 an acute angle, which is filled with a solder meniscus 16 after soldering. Above the solder meniscus, the tube rests against the passage 8 with a relatively narrow gap.
  • the passage 8 forms - like mentioned - with the two outer edge strips 5, 6 of the bottom, the transition areas 12, 13, which here in cross section have the shape of an asymmetrical U and are filled by the Einlegerucn 10, 11.
  • the narrow sides of the passages - is formed by the Einlegearchn 10, 11 a fixed bridge, which prevents deformation of the transition regions 12, 13.
  • the voltage peaks occurring in the prior art are reduced, and the pipe / floor connection is significantly relieved in the narrow sides.
  • the air box 1 can thus withstand higher pressures.
  • Fig. 4 shows a sectional view taken along the line IV-IV, as shown in FIG Fig. 4a is drawn.
  • the passages 8 have - in accordance with the shape of the tubes 9, not shown here - an approximately rectangular inner and outer cross-section, with longitudinal sides 8a and narrow sides 8b.
  • the Einlegearchn 10, 11 nestle against the narrow sides 8b of each passage, ie they have in the region of the narrow sides 8b recesses 10a, 11a in the form of the narrow sides 8b. This mating of the Einlegearchn 10, 11 results in connection with the soldering a very good support of the opposite ground areas, ie a rigid bandage.
  • the recesses 10a, 11a can be produced by embossing.
  • Fig. 4a shows the tube sheet 4 in cross section with the passages 8, which have an outer conical portion 8c and an inner cylindrical (the cross section of the flat tubes 9 adapted) region 8d.
  • the conical region 8c also serves as an insertion bevel for the tube ends 9a.
  • the passages 8 are formed by hole-punching embossing from the tube plate 7 (see. Fig. 2 ) produced.
  • Fig. 5 shows an embodiment in which the Einlegeorn previously described are integrated with the air box, that are formed here in one piece with this.
  • the tube plate 4 is unchanged; the collecting box 17 has connection areas 17a, 17b, the lower edges of which are designed as profiled strips 18, 19 which fill the channel-like transition areas 12, 13 of the floor 4.
  • the same effect - as described above - achieved ie a reinforcement of the transition regions 12, 13.
  • the box 17 is produced as a cast or injection molded part, the rounded profile strips 18, 19 readily by appropriate design of the mold getting produced.
  • the moldings may also be attached to the lower edges of the air box, z. B. by gluing.
