Definitions
- Solder foils for soldering components in particular plates of heat exchangers
- the invention relates to a solder foil for soldering components, in particular plates of heat exchangers according to the preamble of patent claim 1.
- solder When making soldered connections between two components, the solder must be deposited in the soldering gap in a precisely dosed amount before the soldering process. During the soldering process at a temperature above the melting point of the solder material, the solder is melted and fills the soldering gap.
- the solder can be deposited in various forms, e.g. B. as solder paste, in the form of solder grains or as a solder foil, which is used in particular in the case of just formed from soldering surfaces.
- the material of the solder foil is adapted to the material of the components to be soldered, e.g. B. copper or nickel solders are used in the soldering of stainless steel components.
- solder foil was known from DE-C 20 61 825 by the applicant, specifically for soldering cooling elements of a plate heat exchanger, the cooling elements being designed as pairs of disks with enclosed turbulence plates.
- the contour of the solder foil is adapted to the disks and is inserted between a disk and a turbulence sheet.
- solder foils Another application example for the use of solder foils was made known by the applicant's DE 103 28 274 A1, namely in the manufacture Position of a layer heat exchanger in which a plurality of layers, consisting of individual plates, are to be soldered to one another.
- the solder foils are alternately layered with the plates of the heat exchanger in a stack, fixed and soldered in a soldering oven.
- solder foils of the known type are difficult to handle in the manufacturing process, i. H. are tangible or tangible.
- a burr is formed at the interfaces, which leads to the solder foils lying on top of one another and making separation more difficult.
- solder foils lying on top of each other when a layer block is stacked can lead to an increased solder supply during the soldering process and thus to “alloying through” of the plates, ie defective soldering or even brittle phases in the soldering gap
- solder foils can be forgotten, which results in non-soldering, ie also a reject part.
- the solder foil can be produced as part of a band which consists of a chain of individual foils connected to one another by material bridges.
- the solder foil with a specific contour for a specific solder connection is therefore not present individually, but as a coherent band from which a single foil can be separated in each case.
- the material bridges are therefore preferably designed as predetermined breaking points so that the individual foils can be torn off. This eliminates the problem of separating the solder foils, as described above for the prior art.
- the tape with the tearable individual foils can be in various forms are kept in a solder foil dispenser, e.g. B. as a coiled tape ("coil”) or as a zig-zag folded tape, the tear-off edges forming the kinks.
- the tape with the individual foils is wound into a tape roll, a so-called coil.
- the material bridges between the individual foils are designed as webs, which preferably have constrictions to form the predetermined breaking points.
- the solder foil strip according to the invention is preferably produced by punching from a strip-shaped solder foil. A burr that arises, for example, from the punching is harmless in the solder foil present as a tape, i. H. it cannot lead to entanglement as in the prior art.
- the material bridges or webs can be designed as display flags, which remain after tearing off an individual film and protrude beyond the outer contour of the individual film.
- the above display flags serve as a visual check for the complete loading of the stack with solder foils.
- the contour of an individual film is rectangular or square. This results in a particularly simple cut when punching.
- other shapes are also possible, which can be strung together as links in a chain by means of suitable material bridges - for example oval shapes.
- the tearable solder foil is particularly useful in the manufacture of plate or layer Heat exchangers can be used.
- the stack can be completed quickly and reliably, with a mechanical feed of the tearable solder foil also being possible, ie automatic production.
- the solder foil according to the invention is thus particularly advantageous when using robots for the production of layered heat exchangers.
- FIG. 1 shows a layered heat exchanger in an exploded view before assembly
- FIG. 2 shows a band of solder foils according to the invention
- FIG. 3 shows the band according to FIG. 2, but with separate individual foils
- FIG. 4 shows a connecting web between two individual foils as detail X.
- Fig. 1 shows a layered heat exchanger 1, as it is essentially from the aforementioned prior art, i. H. DE 103 28 274 A1 is known, which is included in its entirety in the disclosure content of this application.
- the layered heat exchanger 1 shown in an exploded view essentially consists of a stack 2 and four connection boxes 3, 4, 5, 6 and two cover plates 7, 8, an upper and a lower cover plate.
- the stack 2 is constructed from profiled separating plates 9, which are alternately arranged rotated by 90 °, and solder foils 10.
- the complete manufacturing process including stacking, soldering and welding of the individual parts of the layered heat exchanger 1 is described in the prior art mentioned and is therefore not explained here, but rather reference is made to DE 103 28 274 A1.
- FIG. 2 shows a band 11 according to the invention, consisting of individual interconnected, square-shaped solder foils, so-called individual foils 12, of which three individual foils 12 of an endless band 11 are shown here, for example.
- the individual foils 12 are each connected by metal bridges in the form of two thin webs 13, between each of which a gap 14 is left.
- the endless belt 11 is - what here is not shown - wound into a tape roll, a so-called coil, and in a suitable, e.g. B. drum-shaped, also not shown dispenser rotatably mounted so that individual films can be separated from the end of the coil.
- FIG. 3 shows individual foils 12 'separated from one another, which is preferably done by tearing off individual foils 12'.
- the tearing off can be done manually or mechanically, the latter in an automatic production.
- Fig. 4 shows a detail X from Fig. 2, i.e. H. a section of two adjacent individual films 12 with the web 13, which connects the two individual films 12.
- the web 13 consists of two trapezoidal halves 13a, 13b which abut one another in the region of their short sides and form a constriction 13c.
- the pulling apart of adjacent individual foils 12 causes the web 13 to tear in the region of the constriction, i. H. the constriction 13c forms a predetermined breaking point. This results in a defined tear-off edge when the individual foils 12 are torn off, so that the trapezoidal web halves 13a and 13b are retained on the torn-off individual foils - these form what are known as display flags.
- solder foils 10 shown there would be replaced by the solder foils 12 'according to the invention, i. H.
- Each solder foil would be immediately visible or automatically recognizable as a result of the above “display flags” 13a, 13b. This represents an important control measure during production.
- the finished stack can thus easily be checked for completeness with regard to the number of solder foils.
- the above-mentioned endless belt 11 can be produced as follows: First, a continuous belt (semi-finished product) made of solder foil material, e.g. B. made of copper or a nickel alloy as a coil and supplied to a punching device, not shown. The latter produces the gaps 14 and webs 13 shown in FIG. 2 by punching out thin strips of material. The punched strip 11 is then wound up again into a coil, which is then used for the production process of a layer Heat exchanger, ie the construction of a stack of separating plates and solder foils can be used.
- solder foil material e.g. B. made of copper or a nickel alloy
- the punched strip 11 is then wound up again into a coil, which is then used for the production process of a layer Heat exchanger, ie the construction of a stack of separating plates and solder foils can be used.
