Definitions

  • the invention relates to a flat heat exchanger plate with two closely spaced plates made of poorly or not cold-roll-plateable metal and at least one channel arranged between these plates for a flowing or to be heated or cooled liquid or gaseous medium.
  • the invention finds application in heat exchangers which are used in solar systems, for seawater desalination, in chemical process engineering and in food chemistry, and in particular wherever aggressive or corrosive media are involved as heat carriers.
  • Heat exchangers are used to transfer thermal energy between two liquid or gaseous media of different temperatures, which are either to be cooled or heated.
  • Flat heat exchangers consist of metal plates which have one or more channels for receiving a medium to be passed through them. Such flat heat exchanger plates are used as a stack of plates for compact heat exchangers or as a large single plate, for example for absorbing solar energy.
  • German Offenlegungsschrift 29 02 640 discloses a heat exchange element with two adjacent metal layers made of aluminum and a metal tube arranged between them for the heat transfer medium. Because of the lack of corrosion resistance of the aluminum, the metal tube is made of copper, which causes considerable manufacturing problems.
  • holes must be made in a metal block to accommodate a welding stop agent, which means that the areas of the holes do not weld during subsequent rolling, so that these can be expanded to form channels. The drilling of the holes is, however, quite complex and several additional operations are necessary to remove the welding stop agent, which is essential to prevent undesirable corrosion.
  • German patent 21 23 628 a plate-shaped heat exchanger is finally known, which is made of two strips of a plateable metal by pressure welding, and which has a longitudinal channel lying in the rolling direction. In the area of this later longitudinal channel, a layer is applied to one strip in the area of this later longitudinal channel, which counteracts the welding and enables the channel to be widened.
  • a flat heat exchanger produced in this way is relatively complex to manufacture and can only be produced from conventionally clad metals.
  • the object of the invention is to propose a flat heat exchanger plate or a method for producing such a plate, in which or in which plates consisting of a material which is poorly or not capable of being cold-rolled, can be connected to one another at the intended locations, so that channels are subsequently produced by compressed air can be expanded.
  • a flat heat exchanger plate of the type described above is assumed and the object is achieved in that an adhesive layer of an amorphous metal is provided between the two plates and close to the channel on both sides, and that the plates in the area of Adhesive layer are firmly connected to each other by cold rolling plating.
  • the production of such a flat heat exchanger plate in the cold roll plating process is very simple and metals can be used for the plates by means of the adhesive layer which could not previously be used.
  • the adhesive layer is expediently a film made of an amorphous metal; in their place, an amorphous surface layer can also be provided on at least one of the two plates.
  • the two plates advantageously consist of copper or a copper alloy.
  • the film forming the adhesive layer advantageously consists of an amorphous nickel, iron or copper alloy and contains crystallization-delaying components, primarily silicon, boron, phosphorus, aluminum and / or carbon.
  • each plate has a plated-on top layer, which - if this is a metal which cannot be plated with the plate - is produced according to the inventive concept using an adhesive layer made of amorphous metal.
  • the two cover layers of the plates consist of a metal which is resistant to aggressive and / or corrosive media, titanium or a titanium alloy or tantalum or a tantalum alloy being used as the metal for the cover layer; stainless chrome-nickel steel can also serve as metal for the cover layer.
  • the channels of the flat heat exchanger plate according to the invention take up the aggressive medium, then the two plates will carry their permanent cover layers on the inside, facing the channels, but if the aggressive medium flows on the outer surfaces of the flat heat exchanger plate, then the corrosion-resistant cover layers are on the outside and the two are mostly copper
  • plates are plated onto one another. The use of such a top layer leaves the most economical Use of the very expensive, corrosion-resistant metal too.
  • the adhesive layer is either a film made of amorphous metal or it is applied as a surface layer to at least one of the metal strips.
  • the adhesive layer can consist of strips arranged separately from one another and the strips can be arranged parallel and perpendicular to one another.
  • the adhesive layer advantageously consists of two comb-like strips which are arranged in a toothed manner, this allows the production of a flat heat exchanger plate with a meandering channel which only requires two connections.
  • a metal mesh can be introduced which carries plates made of amorphous metal at at least part of its crossing points.
  • a metal network With the help of such a metal network, the manufacture of a flat heat exchanger plate with multiple branched channels can be easily accomplished.
  • the plates are expediently placed in a die of appropriate shape.
  • the two plates 2 and 3 consist of a metal which is difficult or impossible to connect by a plating process.
  • an adhesive layer 6 is provided, which serves as an adhesion promoter and which is guided to the channels 4 and 5 up to both sides.
  • this adhesive layer 6 the two plates 2 and 3 are firmly connected to one another by cold roll cladding.
  • the adhesive layer 6 consists of an amorphous nickel, iron or copper alloy, which contains crystallization-delaying components, namely in particular silicon, boron, phosphorus, aluminum and / or carbon.
  • This adhesive layer 6 can be a film which is placed between the two plates 2 and 3 before the cold roll cladding, but it is also possible to produce the adhesive layer 6 by irradiating the surface of one of the two plates 2 and 3 with laser light.
  • the two plates 2 and 3 which are made of copper, for example, each carry a more or less thin cover layer 7 or 8, which is applied by cold rolling plating.
  • these cover layers 7, 8 face the adhesive layer 6 or the inside of the channels 4 and 5, but they can - if the application requires - also lie on the outside of the flat heat exchanger plate 1.
  • the two cover layers 7 and 8 consist of a metal which is resistant to aggressive and / or corrosive media, namely titanium or tantalum or a titanium or tantalum alloy.
  • the flat heat exchanger plate shown in Figure 2 is also composed of two plates 2 'and 3', which consist of copper and are connected to each other by cold rolling cladding with the interposition of an adhesive layer 6.
  • a meandering channel 9 is arranged between the two plates 2 ', 3'.
  • the production of the flat heat exchanger plate according to the invention takes place in that an adhesive layer made of an amorphous metal (for example a nickel, iron or copper) is first made at certain points between two metal strips which are unwound from supply rolls and are made of a material which is difficult or not to be plated, namely copper Alloy with crystallization retarding constituents) is introduced. These two metal strips are then joined together by a cold rolling plating process using a rotating pair of steel rollers under high pressure, the Connection only occurs at those points where the adhesive layer is located. The connected metal strips are then cut into individual plates, and finally the recessed, non-connected sections are widened in a conventional manner to form one or more channels for a medium to be heated or cooled.
  • an adhesive layer made of an amorphous metal for example a nickel, iron or copper
  • FIG. 3 shows an adhesive layer 6 made of an amorphous metal in the form of two comb-like strips 10 and 11 made of foils and arranged in an interlocking manner.
  • this adhesive layer 6 flat heat exchanger plates can be produced which have a meandering channel.
  • the dash-dotted line indicates the point at which the cut for cutting the plates is made after the cold rolling plating.
  • a metal mesh 12 for example made of a film, is used to produce flat heat exchanger plates, in which the two plates lying next to one another are only to be connected to one another at certain points to form multiply branched channels, as is shown in a top view in FIG.
  • This metal net 12 carries at a part of its bulging points 13 small, square plates 14, which consist of an amorphous metal. If such a metal net 12, which is preferably made from the metal of the strips, is inserted between the metal strips, which are difficult to plate or not, before the cold rolling cladding, then these are only connected to one another at certain points.
