Definitions

  • the invention relates to a device in which heat is transferred from a first fluid to a second fluid through the wall of hollow filaments and in which the hollow filaments open into distributor or collecting pipes which may be designed as support frames and which have connections for the fluid supply or discharge and with which the end sections of the hollow filaments are connected to the outside in a liquid-tight manner by means of an investment material, and in which at least some of the hollow filaments are at least once continuously or discontinuously curved or bent.
  • This device is, for example, suitable for heat transfer between a gaseous medium, for example air, which flows around the hollow filaments, and a liquid medium, for example water, which flows through the hollow filaments, in particular even at high wind speeds and also ensures an essentially uniform, i.e. with changing wind directions. constant heat transfer performance.
  • a gaseous medium for example air
  • a liquid medium for example water
  • the hollow threads can be designed in the form of an arc of a circle, be angled once or several times, run in a zigzag shape or have a similar shape, it being important that at least some of the hollow threads, but preferably all of the hollow threads, do not run in a straight line, but rather continue in at least one changed direction .
  • the number of hollow threads of the thread sheet forming the heat transfer surface of the device according to the invention can be chosen arbitrarily, the hollow threads of each thread sheet not necessarily having to have the same or a similar shape, but are generally of the same or similar shape.
  • the sheet of hollow fibers is not in one plane, but in a spatially curved surface, for example the shape of the surface of a spherical cap, part of a cylinder jacket, a roof, a dome, a folding wall, a truncated pyramid and the like Has.
  • the hollow fibers can be arranged one above the other in several groups, each group advantageously being able to consist of one or two layers of hollow fibers.
  • the hollow threads of a layer are expediently arranged at constant distances from one another, but can also spread out in a fan shape.
  • the number of hollow threads can also be different in the different layers.
  • the arrangement of the hollow threads of such a hollow thread layer is in any case such that the hollow threads could also be described as being arranged side by side in the broadest sense.
  • the hollow threads of the first layer can cross the hollow threads of the second layer and touch them at the crossing points.
  • these are advantageously arranged at a sufficient mutual distance from one another which can be determined by simple experiments.
  • each hollow fiber layer or group has its own, possibly designed as a support frame, distributor and header pipes for the fluid supply or discharge, which in turn are connected to a common inflow or outflow line.
  • Such hollow fiber layers or groups designed according to the invention, including their distributor and collecting tubes, can be designed in a particularly advantageous manner as module units which can be arranged one above the other or side by side in any number.
  • the common inflow and outflow lines are formed by pipe sockets or connections which interact with one another in the manner of a plug-in connection and are arranged on the distributing or collecting pipes.
  • plug-in connections can be designed to be detachable and self-sealing or else so that after the module units have been joined together by welders, gluing or the like they cannot be releasably connected to one another in a fluid-tight manner to the outside.
  • the stacked configuration of the device according to the invention which is formed in this way can have a square, rectangular, hexagonal, round or any other shape of cross section or cover a base area of the same shape in plan view.
  • the hollow fiber layers or groups can be connected individually or in groups in series or in series, mixed forms also being possible, for example parallel connection of the hollow thread layers of each hollow thread group but series connection of the hollow thread groups.
  • the hollow thread layers or groups arranged one above the other or next to one another can have a curvature in the same direction, but can also be curved alternately in opposite directions, for example in mirror image.
  • Two Oppositely curved hollow fiber layers or groups, the ends of which lie in one plane, can form approximately the shape of a pillow, a lens, a cylinder, a sphere etc., for example, in the case of a surface covering arrangement.
  • the practical design and arrangement of the hollow fiber layers or groups forming the device according to the invention can be easily determined, and it is possible to keep the wind noise generated when the hollow fibers flow around and thus to achieve a low-noise, environmentally friendly device according to the invention.
  • the shape of the hollow fiber layers or groups can be achieved by appropriate design of the distributor or header pipes and / or of support rods, which also give the hollow fiber coulters great dimensional stability.
  • These support rods are expediently arranged such that they cross at least one of the hollow fiber layers and are firmly connected at their points of contact with the hollow threads by welding, gluing and the like.
  • the support rods expediently have a larger diameter than the hollow threads and are arranged at greater distances from one another than these. At their ends, the support rods are advantageously firmly connected to the distributor or header pipes.
  • the support rods can be preformed before they are installed or, for example, can be clamped in an arc in the form of a corresponding excess length when they are installed between two distributor or header pipes.
  • hollow threads suitable for heat transfer can be used to produce the device according to the invention, and these may have been produced by a dry or wet spinning or an extrusion process.
  • hollow thread also includes so-called hollow fibers, thin tubes, thin-walled tubes, capillaries, tubes, plastic tubes and the like.
  • the cross-sectional shape of the hollow filaments used can be of any type, the size of the cross-section of the hollow filaments as well as their wall thickness up and down being subject to no restrictions.
  • the cross-sectional shape, the wall thickness and the size of the cross-section of the hollow filaments can also change along the length of the hollow filaments.
  • Hollow threads with a circular cross-section can have, for example, an outside diameter of 800 1 1m up to 5 mm and above.
  • the wall thickness of the hollow threads can be, for example, 30 to 200 11 m.
  • those hollow threads have proven to be particularly advantageous which have a heat transfer coefficient in the range from 15 to 200 W / m 2 K and above, it also being possible, if appropriate, to use hollow fibers which have improved thermal conductivity properties through the incorporation of metal, Have graphite and the like in dust or powder form.
  • the hollow filaments can also contain fillers, additives, stabilizers, carbon black, dyes and the like. By using porous or microporous hollow filaments, the range of applications of the device according to the invention can advantageously be expanded.
  • the size of the device according to the invention is not subject to any restrictions within the usual dimensions.
  • the center distances of the hollow filaments so that between two adjacent hollow filaments this is 1.7 to 10 times their diameter, in particular 2.5 to 3.3 times.
  • the clear distance between two adjacent hollow threads should expediently be 0.5 to 15 mm, in particular 1 to 10 mm.
  • the dimensions for the distributor or collecting pipes depend on the one hand on the number of hollow threads emanating from them or emptying into them, and on the other hand on the total amount of fluid flowing through the hollow threads, because it is undesirable that in the distributor and manifolds unnecessarily high pressure drops occur. Furthermore, the dimensioning of the distributor and header pipes depends on whether they are also intended to serve as a support frame and should give the device according to the invention a stability which meets the requirements, or whether this should be brought about by other structural measures and devices. Depending on the requirements placed on the distributor or header pipes, they can thus also be provided, for example, with stiffening ribs or the like running in their longitudinal direction. It is also possible Lich, to give the pipes mentioned a flow-wise favorable shape or to achieve the same result by appropriate cladding of the same.
  • rods extending transversely to the hollow threads can be arranged, which can be arranged with the hollow threads are firmly connected at the crossing points.
  • suitable hollow thread groups can also be formed by hollow fiber fabrics. It is also possible to use hollow fiber mats in which the distance between the hollow threads is determined by knitted threads, tapes or the like.
  • a heat exchanger made of elastic plastic hoses in which the hose ends, which are stiffened with an insert made of brass tube, are clamped into clamping bases consisting of four sealing strips which are screwed together by screws.
  • the hose ends open into a common flow channel formed by a hood.
  • the construction of these clamping bases is complicated and does not permit an essentially fluid-tight sealing of essentially inelastic hollow filaments.
  • a heat exchanger in which the flow channels are formed by two bent plastic plates held at a distance from one another by a plurality of parallel ribs.
  • the fluid involved in the heat transfer is supplied or removed to these flow channels via a distributor or collector pipe into which the flow channels open.
  • This heat exchanger can be formed by units in the form of modules, which are connected in series. The units can be arranged side by side or one above the other.
  • pipe pieces provided with O-rings are used, which are inserted into the correspondingly dimensioned header or distributor pipes and screwed down with a screw.
  • the use of screws to fix the pipe pieces in the desired position represents an additional effort and carries the risk that the pipe pieces will be destroyed if screwed on improperly.
  • the present invention is therefore based on the object of improving the externally fluid-tight connections between the end sections of the hollow filaments and the distributor or collector pipes in such a way that the desired sealing is achieved in a faster and simpler manner and with even greater reliability and even longer durability than is the case with the known devices.
  • the improvement of the externally fluid-tight connections between the end sections of the hollow filaments and the distributor or collector pipes is achieved in that the end sections of the hollow filaments are arranged according to the invention in sealing strips and are connected to them externally in a fluid-tight manner, which recesses / recesses match the end sections of the hollow filaments have, and that the sealing strips are sometimes embedded in the distributor or header pipes, but in any case are firmly connected to the outside in a fluid-tight manner.
