Definitions
- the invention relates to a radiator for motor vehicles with a fin - tube - Block consisting of flat tubes with ribs arranged between them, whereby the formed ends of the flat tubes in opposite collecting or Deflection boxes open and with the long sides of the formed ends with each other are connected, the ends of the flat tubes with the connecting edges the collecting or deflection boxes in contact and connected by soldering are.
- the invention further relates to a method for producing such coolers, in which the finned tube block is soldered to the collection or deflection boxes at the same time become.
- coolers have long been state of the art, such as the DE - PS 1 551 448 from 1967 or the German utility model No. 1 519 204 from 1940.
- the newer German differs from this Registration No. 195 43 986 A1 only insignificant.
- a disadvantage of the prior art mentioned is the considerable degree of deformation, which the pipe ends are subjected to, which is why high-quality materials are necessary.
- the flat tubes have rectangular formed ends, whereby in usually the large diameter of the rectangles is much smaller than that large diameter of the flat tubes. This constriction leads to fluidic Disadvantages.
- the object of the invention is to eliminate the disadvantages listed or weaken.
- the flat tubes from two Pipe halves exist, of which at least one pipe half at its end transverse to Is bent in the longitudinal direction, wherein the bend is a long side of the flat tube forms approximately with the end of the long side of the adjacent flat tube forms a connecting surface and that the collecting or deflection boxes with their connecting edges extend beyond the turn and with the Longitudinal edges of the tube halves is connected.
- the cooler according to the invention leads to the following advantages. Because there are only relatively small bends at the end of the flat tubes no high-quality material has to be used. The material load is extremely low. There is also no constriction at the ends of the flat tubes, so that a much lower pressure drop is to be expected than at the state of Technology. The flow cross-section at the ends was even expanded, though there is no significant material expansion. Furthermore, much less The use of materials is more important than in the prior art, because in the area of the connecting edges the collection or deflection boxes do not have a double wall is, because the longitudinal edges of the flat tube halves are directly at the connecting edges the collection or deflection boxes connected.
- the method according to the invention provides that flat tube halves made from sheet metal strip while reshaping the longitudinal edges and to length be cut that then either first at the ends at least one the flat tube halves of each flat tube at least one bend perpendicular to Longitudinal direction of the flat tube halves is attached and then when joining of the ribbed flat tube block connecting surfaces between the bent End of a flat tube half with the end of the adjacent flat tube are formed or that the flat tube halves are first joined together to form flat tubes and put together with the ribs to form a rib - flat tube block and then the ends of at least one flat tube half of each flat tube by inserting a tool so far that they can be bent with the ends of the flat tube half of the adjacent flat tube a connecting surface train and that the collection or deflection boxes with their connecting edges be pushed over the longitudinal edges of the flat tube halves.
- the claim 3 is mainly intended for coolant coolers.
- the claim 4 is used in particular for charge air coolers.
- the flat tube halves can be identical, but they can also be different Flat tube halves are used.
- the longitudinal edges of the flat tube halves are formed so that both flat tube halves have a substantially rectangular cross section of the flat tube form.
- claim 12 provides that the narrow sides of the Flat tubes forming the longitudinal edges of the tube halves are merely folded and in a weld seam on both opposite narrow sides of each flat tube is arranged, which connects the tube halves.
- Developments of this version are the subject of claims 13 to 15.
- the welds are located in the middle plane of the flat tubes or in the middle between the two broad sides. With different flat tube halves the welds are arranged outside the median plane.
- the inventive method for manufacturing the heat exchanger in the subordinate Claim 17 looks at welded used according to claim 12
- Flat tube halves as a further alternative that profiled U-shaped from sheet metal strip Tube halves are made so that the tube halves are cut to length, that bends are made at the ends of the tube halves that two pipe halves joined together to form a flat pipe and along the Narrow sides of the flat tube are welded and that the flat tubes and Ribs are then joined together to form a rib - tube block, with connecting surfaces between the broad sides of adjacent flat tubes at their ends be formed.
- the ends may either have two ends Turns or around one end with turns and one not turned so act a straight end. If you decide to do this, only one at a time Provide flat tube half of each flat tube with bends at both ends, it’s an advantage if this step is done after cutting.
- the tube halves which are practically U-shaped profiles with relatively short legs, with smaller bending radii are producible, whereby a much better process reliability at subsequent soldering of the cooler is achieved.
- This mainly affects the Connection between the connecting edges of the collection or deflection boxes with the narrow sides of the flat tubes to where the broad sides of neighboring Form flat tubes connecting surfaces.
- the manufacture of the U-shaped Profiles from sheet metal strips connected with less tooling effort, because in this alternative the longitudinal edges of the tube halves have no folds or have profiles.
- the coolers 1 consist of flat tubes 2 and corrugated fins 3 arranged between them .
- the corrugated fins 3 were not shown in FIGS. 1 and 2, but can be seen in FIG. 3.
- the flat tubes 2 have been composed of two tube halves 2a and 2b , as shown in FIG. 2.
- the partial view in FIG. 1 shows only one header box 5. It goes without saying that the other header box 5 is arranged identically at the opposite ends of the flat tubes 2 .
- the collecting boxes 5 are of the simplest geometrical shape, so that their production is possible very inexpensively using known methods of forming technology.
- Each collecting box 5 has two connecting edges 7 with which it the longitudinal edges 10 of the tube halves 2a; 2b overlaps at the ends 4 .
- Two tube halves 2a and 2b each result in a flat tube 2.
- the tube halves 2a and 2b are produced from sheet metal strip on systems equipped with roller sets, which is part of the prior art and is not shown in detail here.
- FIG. 8 in which, starting from the sheet metal strip 21, first a longitudinal bead 11 and then the longitudinal edges 10 of the tube halves 2a and 2b are blended out, which are identical in this exemplary embodiment.
- the longitudinal edges 10 are first erected and then looped over, including a free space 13 .
- 11 corresponds to the design of the tube halves 2a and 2b described above .
- FIGS. 12, 13 and 14 show designs which have different tube halves 2a and 2b or longitudinal edges 10 .
- edges can also have folds 15 .
- a common feature of all longitudinal edges 10 is seen in the fact that they have been chosen so that two tube halves 2a; 2b lead to an approximately rectangular flat tube 2 . Care was also taken to ensure that the longitudinal edges 10 are wide enough to form a firm and tight soldered connection with the connecting edges 7 of the collecting boxes 5 .
- the tube halves are cut to length using known technology.
- the ends 4 of the tube halves 2a, 2b can be bent. In the following examples, however, only the alternative production is discussed in more detail, in which the bends are produced on the assembled fin-tube block.
- the wedge-shaped tool 25 required for this has been indicated schematically in FIG. 3. In contrast, a somewhat different tool 25 was used in FIGS.
- All components of the cooler 1 shown are made of aluminum, which is expediently coated with solder.
- the collecting boxes 5 are placed, as shown in FIG. 1 .
- a closure wall is, as shown in FIGS. 3 and 7, 12 is inserted.
- the entire cooler 1, ie all of the described individual parts of the cooler 1 are connected in a single operation in the soldering furnace. 3 and 7, the cooler 1 has no side parts 22.
- the cooler 1 shown in FIG. 10 has such side parts 22, only the right side part 22 being drawn there.
- An identical side part 22 is located on the left side of the cooler 1, not shown .
- the side part 22 has been extended into the collecting box 5 , so that the extensions can also take over the function of the closure wall 12 described above.
- the outer pipe half 2b is also connected to the side part 22 with its connecting surface 9 . Such a connection is also provided in FIG. 7 with the closure wall 12 , thus making a contribution to the strength.
- Fig. 4 is the section AA through the cooler 1, which has been drawn in Fig. 3 just below the end of the flat tubes 2 .
- This cooler 1 is a coolant cooler, the flat tubes 2 of which each have two flow channels 16 .
- the flow channels 16 result from the fact that the tube halves 2a; 2b have longitudinal beads 11 which touch over the entire length of the flat tubes 2 and are also soldered.
- Another embodiment, not shown, has a large number of such flow channels 16.
- FIG. 6 shows, on a larger scale, what the connection of the longitudinal edges 10 of the flat tubes 2 to the connecting edge 7 of the header boxes 5 looks like in this area.
- FIG. 5 is the section BB which has been placed exactly through the connecting surfaces 9 of FIG. 3, that is to say above the section AA described above. From this it can be seen that in the connection area 9 the abutting pipe halves 2a, 2b are essentially smooth, so that the durability and the tightness are guaranteed. Both Figures 4 and 5 show sections that run within the connecting edges 7 of the header boxes 5 .
- a useful flat tube 2 for a charge air cooler has been shown schematically in cross section.
- This flat tube 2 also consists of two tube halves 2a and 2b, which have an inward-facing longitudinal rim with which they are connected to one another.
- a corrugated fin was selected as the inner insert 14 .
- FIGS. 17 to 27 show another embodiment in which welded flat tube halves 2a, 2b are provided and which is described below.
- Two tube halves 2a and 2b each result in a flat tube 2, which is known to have narrow sides 10 and wide sides 6 .
- the sheet metal strip 21, which is bent at both longitudinal edges and results in a flat tube half 2a is shown in FIG. 19.
- the flat tube halves 2a; 2b have very small bending radii r at the two bevels.
- improved process reliability is achieved when the narrow sides 10 of the ends 4 of the flat tubes 2 are to be subsequently soldered to the connecting edges 7 of the collecting tank 5 . This is particularly evident from FIGS. 22 and 23.
- two identical flat tube halves 2a; 2b used, which has the advantage that no changes to the setting have to be made on the system.
- the bent sheet metal strip 21 is cut to length, so that individual cut flat tube halves 2a and 2b are present.
- the bends 8a and 8b are formed on the ends 4 of the flat tube halves 2a and 2b .
- the weld seam 20 can be a laser weld seam. The use of other modern and efficient welding processes is also possible. It is preferably welded without filler metal.
- the fins 3 - flat tube 2 - block are assembled.
- the ends 4 of one flat tube 2 touch with the ends 4 of the adjacent flat tube 2 and form connecting surfaces 9 along the broad sides 6 of adjacent flat tubes 2 .
- the collecting boxes 5 are attached to the ribbed flat tube block, as can be seen in FIGS. 1 and 3.
- the connecting edges 7 of the header boxes 5 extend slightly beyond the weld seams 20 in the narrow sides 10 of the flat tubes 2 in order to ensure a tight solder connection. Slight differences in the start and end of the weld seams 20 and the welding craters that usually form there, which cause problems with the tightness, can be compensated for quite easily.
- FIG. 22 shows the section AA from FIG. 3, which was placed in a plane in which the flat tube halves 2a and 2b are already connected by means of the weld seams 20 .
- the weld seams 20 were not shown in FIG. 22. However, they emerge from the detail "U” shown in Fig. 24. No excessive weld seams occur or they are so slight that they have no influence on the tightness of the soldered connection with the connecting edges 7 of the collecting boxes 5.
- FIG. 23 shows section BB from FIG. 3, which was placed in a plane that passes through the connecting surfaces 9 .
- the connecting surfaces 9 are formed by the broad sides 6 of adjacent flat tubes 2 which abut one another in this region. Since, as mentioned at the beginning, the bending radius r on the flat tube halves 2a; 2b is very low, the risk of leaky soldered connections between the connecting edges 7 of the header boxes 5 and the narrow sides 10 of the flat tubes 2 has been substantially reduced in the area shown in FIG. 23.
- connecting surfaces 9 can also be seen in FIG. 25, which shows an enlarged detail from FIG. 23. As mentioned above, they arise when the flat tubes 2 are joined with the ribs 3.
