  • a first collection box section tabs while a second header section has recesses, so that by engaging the tabs in the recesses one Connection between the two SAmmelkastenabêten is made.
  • the collection box is preferred formed from a formed sheet metal blank, so that the part number the heat exchanger is particularly low, since the collection box then only consists of a single part.
  • the connection between the both longitudinal edges or longitudinal edges of the sheet metal blank in the bottom area arranged in the collecting box and through in recesses of the soil secured with tabs It is essential that the wall longitudinal edge and the bottom longitudinal edge are almost perpendicular to each other, wherein under the longitudinal edges no edges in the sense of lines, but the longitudinal edges or edge regions of the wall and floor sections are to be understood.
  • the tabs are arranged vertically in the slots, d. H. the tabs essentially form a right-hand side with the bottom longitudinal edges Corner.
  • the tabs ensure, in particular, if they are caulked, a firm connection as they solder the connection mechanically support.
  • the cross section of the collecting tank above the essentially flat floor area and outside the longitudinal wall edge can be arbitrary.
  • the recesses arranged in a bead or gutter will improve the Solder connection achieved because when soldering sufficient solder in this bead collects and thus given a sufficient Lot on for a Dichtlötung is.
  • the soil in the area the recesses are set up, d. H. so angled that a Lotstrom Chemistry for soldering wall and floor longitudinal edge results.
  • the Solder connection at the connection point is thereby improved.
  • the wall portion curved, z. B. semicircular or oval or even a flat angled surface - what z. B. for reasons of installation in the vehicle is an advantage.
  • the Longitudinal edge of the floor beyond the recesses and is in this Angled area to a stiffening profile. This will increase the strength or flexural rigidity of the bottom longitudinal edge and the solder joint improved.
  • the bottom longitudinal edge is upwards or below, angled in whole or in part and forms a longitudinal ridge or individual flanges or holders for the attachment of additional parts, eg. B. one Condenser or fan cowl.
  • Fig. 1 shows a coolant / air cooler 1 in Ganzaluminiumbauweise for a coolant circuit, not shown, of an internal combustion engine of a motor vehicle.
  • the coolant radiator 1 consists of a heat exchanger network 2 and laterally arranged collecting tanks 3, 4 and side parts 5, 6.
  • the heat exchanger network 2 consists of flat tubes, not shown, and arranged between these corrugated fins, which are acted upon by ambient air.
  • the radiator 1 is fastened in the front region of a motor vehicle (not shown) and has four attachment pins 7, 8, 9, 10 arranged on the manifolds 3, 4 or the side parts 5, 6 for this purpose.
  • an inlet connection 11 is arranged in the upper region of the collecting tank 3, and an outlet connection 12 is arranged in the lower region of the collecting tank 4.
  • the cooler 1 is preferably installed as a cross-flow cooler, ie with vertically arranged collecting boxes 3, 4.
  • the headers 3, 4, which are explained in more detail below, are frontally closed by cover 13, 14. All parts consist - as mentioned - of an aluminum alloy and are soldered "in one shot” in a soldering oven, preferably in the so-called Nocolok process, which is particularly advantageous for a Dichtlötung the header tank and heat exchanger according to the invention.
  • Fig. 2 shows a collecting box 15 in cross-section in its basic form. It consists of a bent to a closed hollow profile metal strip 16, a flat bottom portion 17, an approximately vertical, flat wall portion 18, a curved wall portion 19 and a flat recirculated wall portion 20 has.
  • the flat bottom portion 17 terminates in a bottom longitudinal edge 21, while the returned wall portion 20 terminates in a longitudinal wall edge 22.
  • At the longitudinal wall edge 22 - distributed over the length - individual tabs 23 are arranged, which are also visible in Fig. 1.
  • a longitudinally extending bead 24 is formed, in which - distributed over the length - recesses 25 for receiving the tabs 23 are arranged.
  • the sheet-metal plate 16 is preferably solder-plated on both sides, so that when soldering in brazing furnaces solder also runs from the vertical wall section 20 down into the channel 24 and thus good soldering both the longitudinal wall edge 22 with the bottom longitudinal edge 21 and the tabs 23 with the recesses 25th guaranteed.
  • Fig. 2a shows a modified connection point between a longitudinal wall edge 22a with a tab 23a, which is inserted into an associated slot 25a of a bottom portion 17a.
  • the bottom portion 17 a is continued in a bottom longitudinal edge 21 a, which is positioned vertically next to the recess 25 a, so that the wall longitudinal edge 22 a comes to rest on the raised bottom longitudinal edge 21 a.
  • Fig. 2b shows a modified cross-sectional shape for the collecting box with a semicircular curved wall portion 20b, which ends in a longitudinal wall edge 22b with a tab 23b.
  • the tab 23b is passed vertically through the bottom portion 17b, and also the longitudinal edge 22b forms approximately a right angle with the bottom portion 17b.
  • the wall merges into a circular curved wall section 20b.
  • Fig. 2c shows a modified junction between a flat bottom portion 17c and a longitudinal wall edge 22c with a tab 23c, which in turn is guided and inserted vertically through the relevant recess 25c through the bottom 17c.
  • the wall of the collecting tank or the sheet metal plate kinks in a planar portion 20 c which z. B. may be required due to the installation conditions in the vehicle.
