  • the inventive design, the radiator assembly and the radiator is particularly suitable for connection conditions in which the inflow or outflow lines are arranged in the immediate vicinity of the radiator assembly or the radiator.
  • spigots are usually placed in the wall of the header tank, which must then be provided with a corresponding opening with a soldering rim.
  • the present invention leads to reduced manufacturing costs.
  • the cooler thus leads not only in connection with the cooler arrangement to the mentioned advantages, but also when it is used as a single cooler.
  • the cooler arrangement has been further improved in compactness, as in the application the entry and exit has been provided by the end faces of the collecting boxes, ie transversely to the direction of the flat tubes and not in a row, whereby a little more space is claimed.
  • direct neighborhood is to be understood that touch the end of the flat tube and the connecting piece of the inlet or outlet lines or have no component between them, whereas in the indirect neighborhood z.
  • the coolers of the arrangement consist either (and preferably) of coolers having tubesheets, such as those of the application DE 199 50 753.8 (claims 2 and 3) or at least some of the coolers can also according to the applications DE 100 16 113 8, DE 100 19 268.8 or DE 100 33 070.3 be formed without tube bottom, (claims 4 and 5). These applications are expressly incorporated by reference. Features not mentioned here which may be required for feasibility are contained in the latter applications.
  • the connecting pieces preferably have a rectangular flow cross-section.
  • the one end of the connecting piece is designed so that the end of the inlet or outlet line can preferably be connected by means of plug connection.
  • the connector itself may be known.
  • the connecting pieces are made of aluminum and they are coated with solder as needed, so that they can be used in the production of the respective radiator of the cooler assembly with equal and soldered.
  • coolers with tubesheets there is an opening in the tubesheet which correlates with the connecting piece.
  • the opening is surrounded by a passage, which forms a suitable soldering edge for connection to the connecting piece.
  • one end of the connecting piece opening similar to the ends of the flat tubes is formed into a rectangle in the collecting box.
  • the one longitudinal side of the rectangle is located on the longitudinal side of the outermost flat tube or on a side part.
  • the opposite longitudinal side is the connecting edge of the end wall of the collecting tank comprises and the two short sides of the rectangle are bordered by the connecting edges of both longitudinal sides of the collecting tank.
  • inlet and outlet lines of elbows, sleeves, T-pieces, cross pieces and straight or bent line sections can be assembled in a modular manner as required.
  • cooler arrangements wherein different coolers of the arrangement are fluidically connected, as described for example in claim 7, can be produced more economically and using identical parts.
  • the elbows, sleeves, T - pieces and cross pieces are preferably plastic injection molded parts, while the pipe sections are preferably made of aluminum, for example, formed as extruded profiles.
  • the arrangement of the inlet and outlet lines is chosen so that the flow resistance to all the coolers involved are about the same size, so that the amount of the agent to be cooled, which flows through each cooler is about the same size without the use of flaps or other regulatory organs.
  • the radiator arrangement has a front wall F and a rear wall R.
  • the flat tubes 8 of all radiators 1, 2, 6 extend transversely to the fan axis V. They were drawn in Fig. 1 only in the upper radiator.
  • On the rear wall R are inflow 3z and on the front wall F drain lines 3a.
  • the coolers 2, 6 and 7 are cooling liquid coolers which are connected by means of the inflow and outflow lines 3z and 3a .
  • the radiator 7 is arranged opposite to the radiator 6 , as can be understood from FIG.
  • the radiators 1, 2, 6 and 7 each have two header tanks 5, each two headers 5 adjacent radiator 2, 6 form an edge of the radiator assembly, where they are close to each other to complete the radiator assembly and thereby force the sucked by the radial fan 10 cooling air to flow through between the flat tubes 8 of the radiator. From Figs. 2 and 4, the adjacent collecting tanks 5 can be seen.
  • the inflow ducts 3z and the outflow ducts 3a consist of straight duct sections 23, bent duct sections 26, elbows 24 and crosspieces 25 connected by connecting sleeves 13 . They can be plugged together using gaskets.
  • the straight and bent pipe sections 23; 26 are made of extruded aluminum profiles.
  • the manifold 24 and the cross pieces 25 are molded plastic parts. With such a configuration, any circuit variants, ie fluidic connections of several coolers, can be realized cost-effectively.
  • FIGS. 1 to 5 The inlet and outlet lines 3z and 3a were now connected in a very special way to the manifolds 5 , whereby the radiator assembly but also each individual radiator receives a very compact and space-saving design.
  • the circled in FIGS. 1 to 5 ports A are shown in more detail in FIGS. 6 to 12 in several variants and will be described below. As the above figures show, only the port A has been shown to each of the individual coolers 2, 6 or 7 , which can then be assembled to the radiator assembly as described above.
  • FIGS. 6 to 8 illustrate a variant in which coolers 2, 6, 7 are used, which have opposite tubesheets 11 , of which only one is shown.
  • the tubesheets 11 have a number of openings in a known manner, in which the ends of the flat tubes 8 open, they form orifices 22. Furthermore, the tubesheets 11 a supernatant 17, ie they go well over the first or last flat tube 8.1 of the flat tube row out. The supernatant 17 is covered by the end of the collecting tank 5 , as shown in FIG. 6. In the supernatant 17 there is an opening 15 in which the end of a connecting piece 12 fits into and thereby forms the mouth 21 .
  • the opening 15 has a passage 18, comparable to the passages 18 at the openings provided for the flat tubes 8 , which form the orifices 22 . In the embodiment, the passages 18 have been mounted or directed inward.
  • the passages 18 for out of the flat tubes 8 and the corrugated fins 9 cooling network out so to the outside.
  • FIG. 6 in particular the indirect neighborhood in this case between the connecting piece 12 and the last flat tube 8.1 of the flat tube row can be seen. Indirectly, the neighborhood is because the cooler has a side part 16 and an outer corrugated fin 9 , which are arranged between the connecting piece 12 and the flat tube 8.1 .
  • the mouth 21 of the connecting piece 12 in a row with the mouths 22 of the flat tubes 8; 8.1 has been arranged.
  • the cross section of the connecting piece 12, in the region of its mouth 21, is approximately rectangular in shape in this embodiment.
  • the connecting piece 12 also has at the opposite end of the mouth 21 a connecting sleeve 13, the connection of the supply or discharge line 3z; 3a serves as already explained above.
  • the headers 5 can z. B. made of aluminum, in which case the connection edges 20 of the manifolds 5 can be connected to the tube sheets 11 and at the same time all other items by means of soldering.
  • this embodiment also allows the use of collecting tanks 5 made of plastic, in which case the connecting edges 20 must be mechanically and tightly connected to the tube sheets 11 in a known manner.
  • FIGS. 9 to 11 and FIG. 12 show two further variants of the connection A. These are coolers which have no tubesheets 11 .
  • the ends 30 of the flat tubes 8; 8.1 have bends in such a way that the ends 30 abut each other with the longitudinal sides 31 of adjacent flat tubes 8 and can be connected by means of soldering.
  • In indirect proximity to the first flat tube 8.1 of the connecting piece 12 is arranged. In between is the end of a corrugated fin 9 and a side part 16.
  • the mouths 22 of the flat tubes 8; 8.1 and the Mouth 21 of the connecting piece 12 are also in this case in a row, as shown in FIGS. 10 and 11 can be seen.
  • the mouth 21 of the connecting piece 12 has been shaped approximately rectangular.
  • the collecting box 5 shown in Figure 9 partially attached, in such a way that its connecting edges 20, the ends 30 of the flat tubes 8; 8.1 at the narrow sides 32 and the end of the connecting piece 12 include. Since the entire radiator of this embodiment is made of aluminum, all connections can be made with a soldering operation. As can be seen from the above description, this variant is therefore particularly suitable for coolers made entirely of aluminum.
  • Fig. 12 also shows a "tube bottomless” radiator, which is completely, that is, including the manifolds 5, made of aluminum.
  • the connection piece 12 was arranged in the direct vicinity of the first flat tube 8.1 in FIG. The rest of the training may be identical to that described.
  • the drawing in Fig. 12 also includes the connection edges 20, which are part of the collection box 5, which is not otherwise shown.
