Definitions

  • the present invention relates to a fluid distribution element for fluid-carrying devices, in particular for devices having multi-channel tubes. Such an element is out DE 4426097 A known, and corresponds to the general concept of the claim1.
  • the fluid distribution element according to the invention is alternatively referred to below as distributor connection piece, fluid distribution device or fluid collection device.
  • the present invention also relates to an arrangement of such fluid distribution elements and to manufacturing processes for producing such fluid distribution elements.
  • Fluid distribution elements are of particular interest when heat or mass transfer between multiple carriers (fluids) is to take place at the same time.
  • An example is tube-in-tube heat exchangers Air conditioning systems in the automotive industry, which serve as internal heat transfer for the refrigeration circuit. Essential here is in particular the fulfillment of requirements in terms of space requirements and weight reduction and as to the cost reduction.
  • Another example in which fluid distribution elements can be used are so-called combination evaporators (also abbreviated to Kombiverdampfer) for heat pumps, as described for example in the patent WO 2004/094921 A1 to be discribed.
  • the present invention is achieved by a fluid distribution element according to claim 1 and by an arrangement of such fluid distribution elements according to claim 9.
  • Advantageous embodiments of the fluid distribution elements or arrangements according to the invention can be found in the dependent claims.
  • Inventive methods can be found in claims 13 and 14. Uses according to the invention are described by claim 15.
  • a fluid distribution element or a fluid distribution device / fluid collection device in particular of metal or plastic, is provided, which is suitable in particular for connection to interleaved or overlapping multichannel-type lines (multiple channel tubes).
  • multi-channel pipes are to carry one or more different fluids separately in a space-saving manner independently of each other and to utilize the possibility of controlled heat transfer or controlled mass transfer.
  • multi-channel pipe heat exchangers offer the advantage that they allow the heat exchange between different heat transfer media (for example, from two different heat sources with different temperature levels and with different heat transfer composition and a heat sink) in a reduced space.
  • Multi-channel pipes offer, inter alia, the advantage that they allow the controlled mass transfer between more than two fluids in a reduced space, for example by means of the diffusion, osmosis or sieving principle.
  • the present invention provides a fluid distribution element or manifold connector, the purpose of which is to connect, on the one hand, monotube leads to, on the other hand, a multichannel tube, without having to penetrate the channels.
  • the inventive approach is that the individual supply channels open in sub-channels and these sub-channels intersect and overlap, so that a contact surface for the purpose of heat and / or mass transfer arises.
  • the fluid distribution element or connector can advantageously made of metal or plastic and with different cost-effective methods (for example, pressure welding, gluing and / or soldering) are produced.
  • the fluid distribution element according to the invention has a very small space requirement and simplifies the concatenated connection of multi-channel tubes for the purpose of constructing a compact unit for heat transfer.
  • the fluid distribution element according to the invention can be produced in a structurally simple manner, without there being an increased risk of leakage, as in the prior art at the penetration points.
  • the structure of the fluid-carrying device by means of the fluid distribution elements can advantageously be such that bionic approaches are tracked in the route of the channel.
  • the fluid distribution element according to the invention has a plurality of individual layers stacked one above the other (for example, flat metal layers or plastic layers), which are connected to each other with parts of their surfaces. Between such connection areas, bulges or elevations are realized (for example, by swelling of partial areas of the surfaces which were provided with a release agent or also by preforming) perpendicular to the layer plane, which then form spaces between the individual layers, by means of which fluid guide channels are realized.
  • it is a stack arrangement of three, for example, pressure-pressed material layers, particularly advantageous (see also the following embodiment) are four layers of material used.
  • such a fluid distribution element according to the invention can also be produced cost-effectively and fully automatically by bonding preformed plastic or metal parts in which half channels are already preformed.
  • a fluid distribution element according to the invention is therefore in the simplest case a structure with substantially circular or semicircular flow cross sections (tubes) which are pre-embossed into flat bodies (the individual layers) which in this variant are glued or soldered to other flat bodies.
  • the connecting pipe pieces, which are connected to the leads conclusively become.
  • the channels do not overlap in or between the individual layers.
  • Single layers of metal are used for the above-described roll-bonding process (or autogenous rolling welding). It is applied a suitable release agent at the locations of the channels to be formed and the sheets are cold-welded together by rolling.
  • the release agent leaves unconverted areas exist, which can be expanded with a fluid, in particular air, pressurized into tubes.
  • a fluid in particular air, pressurized into tubes.
  • the sequence of expansion of the regions which are not disposed of. For example, the space between the inner, centrally located individual layers or individual layers is first widened, and then the space between individual layers lying further outside. In order to preserve the channel structure of already inflated channels, it is possible to leave them under pressure as more channels are inflated.
  • the individual layers of the fluid distribution element or distributor connection piece can easily be connected to one another and then individual fluid distribution elements or distributor connection pieces stacked perpendicular to the layer plane and connected to supply lines, so that a stack (arrangement) of distributed, piled and provided with fluid guide channels fluid distribution elements.
  • the design of such an arrangement of fluid distribution elements according to the invention can then be designed similar to a lamella heat exchanger, in which the tubes form a closed body with the lamellae.
  • an arrangement of fluid distribution elements or a Merrives fluid supply unit using multiple fluids can be formed, between the individual (coated from individual layers) fluid distribution elements or around the stack spaced apart individual fluid distribution elements, which now serve as fins, an example gaseous fluid can flow.
  • Spacers can be arranged between adjacent individual fluid distribution elements or plate bodies, which can be selected such that sufficient fluid can flow or flow past between individual fluid distribution elements.
  • surface structures such as ridges or ribs, which have a turbulence-increasing effect, can be applied to the outer surfaces of the fluid distribution elements according to the invention. This leads to an improved heat transfer between a fluid flowing in a fluid distribution element according to the invention and the fluid flowing between it and an adjacent fluid distribution element.
  • the above-described type of preparation for the individual fluid distribution elements or the entire, the arrangement of fluid distribution elements having fluid guide unit brings in addition to the advantage that no soldering or welding are necessary, also the advantage that they or it with the same conventional inexpensive metals or plastics, as the multi-channel pipes to be connected can be generated itself.
  • the connections on the front side of the Eizelrohrzu füren are advantageously formed with a circular cross-section and selected with a standardized inner width, so that a connection with conventional lines and Kochsch scholaren can be done easily.
  • the cross-section of the channels can remain constant along the route, so that pressure or flow is constant remain, or be varied, so that physical phenomena, such as evaporation or compression can be specifically favored.
  • the distributor connection piece or fluid distribution element according to the invention is thus characterized by a simple structure and a simple production and by low material costs.
  • the shape of the plates can be arbitrary (seen in the layer plane), for example in a rectangular or polygonal shape.
  • the entire combi-steamer is not conventionally manufactured as a lamellar tube heat exchanger made of aluminum fins and tube registers made of copper, but it is a multilayer body of at least four individual layers realized (for example, with the above-described rolling bonding method).
  • certain areas in the intermediate layers or between the individual layers may be excluded from a joining compound which will expand at the disposal of the other areas or are already pre-embossed when in use and thus form areas between the individual layers for the flow of fluids (ie channels).
  • An exception here is the production by extrusion, whereby structures without branches and returns can be made in one piece.
  • the flow-through areas in the intermediate layers may also include more complex structures, such as branches and returns.
  • the fluid distribution element according to the invention is also used of the fluid distribution element according to the invention in Kombiverdampfer the structure simplified so that leads are no longer complex shapes with penetrations, but that the problem of penetration is shifted to the multilayer body.
  • the bodies through which it flows are then tubular channels or channel-like tubes.
  • the multilayer panels are shaped to achieve functionality analogous to the combination steamer, which is accomplished by cold welding a body having advantageously four layers of panels, for example, in the roll bond technique. This results in a total of three intermediate layers or areas between two adjacent individual layers, which are available either by release agents or by the use of pre-stamped structures for the fluid guide available.
  • the individual layers can also be soldered or glued, in which case channel guides represent recessed areas.
  • This multi-layered body can then be used to make a channel system overlying the flow filaments.
  • These outer channel systems can in this case be separated from each other by two further plates, which may be necessary because during the later continuation of these channels, the channel in the middle intermediate layer laterally penetrates into the outer channels. This process of lateral penetration corresponds to the penetration in the previous production of supply lines or distribution lines.
  • Y-shaped branches can also be produced.
  • a Y-shaped branch piece which in combination can be used with a fluid distribution element according to the invention or can be connected to this, applies, for example, if a multi-channel pipe must be divided into two parallel multi-channel pipes (for example, for the purpose of reducing pressure drop in the same transfer area in Kombiverdampfern).
  • a release medium may be applied to the ply planes according to the shape and arrangement of the branch.
  • the present invention thus provides a metal or plastic manifold connector for nested multi-channel fluid routing apparatus consisting essentially of separate leads on one side (first face) and interleaved channels on the other face (second, first face) Front side opposite end), wherein the channels do not penetrate, but in separate sub-channels (closing the multi-channel tube) open, with these sub-channels intersect and partially or completely overlap, so that a contact surface for heat or mass transfer via an intermediate Canal wall is created.
  • the supply or removal of fluids to or from the heat exchanger in separate, not superimposed channels so that the supply line can be connected on one side with conventional Einrohrön.
  • the element according to the invention can be produced by roll bonding or pressure welding from a plurality of individual layers (advantageously at least three or four individual layers).
  • the channel-like Structures can be created by puffing.
  • the channel-like structures can alternatively also be provided by pre-stamped channel structures in the individual layers.
  • the individual layers can also be cast or bonded together by gluing.
  • a plurality of fluid distribution elements according to the invention can be stacked on top of one another and at a distance from each other, preferably perpendicular to the layer plane, whereby a heat exchanger with a plurality of multiple-channel tubes or several flights within the fluid-guiding unit is formed. Between each individual fluid distribution element of such a fluid-guiding unit, a further fluid can then flow through corresponding fluid-carrying structures.
