Lr * t l f f L .vXvjöj- 5 - L J Subject of the invention of the main patent Â.U. (P — 2 · 8 ~ 41 '· β9Ί-Γ5) is a thin-walled tube made of a melt-spinnable synthetic polymer, characterized by a flow cross section of 30 to 95% of the total cross section and an elongation at break of less than 100%. A "thin-walled hose" in the sense of the invention of the main patent is a hollow cylindrical structure of any length with, for example, circular or elliptical cross-section, the wall thickness of which is substantially constant in the longitudinal and circumferential directions and is less than approximately 15% of the largest external dimension of the hose cross-section. In the case of a circular cross-section, the largest outer dimension - 6 - 1 ^ /% »• Γ Ί A3GW31861 / A - 6 - corresponds to the outer diameter, in the case of an elliptical cross-section it corresponds to the large outer axis. The thin-walled hoses according to the main patent show against? higher strength than conventional thin-walled hoses, but still have a large passage Flow cross-section and a closed, i.e. undamaged coat. They are characterized by a flow cross-section which is in the range from 30 to 95% of the total cross-section and by an elongation at break of 'i less than 100%. Tubes which have a flow cross-section of 60 to 95% of the total cross-section are preferred. The thin-walled tubes according to the main patent can be made from all common melt-spinnable polymers. Because of their special properties, the polyamides, in particular polycaprolactam and polyhexamethylene adipamide, are particularly suitable. Polyesters, in particular polyethylene terephthalate, polyolefins, in particular polyethylene and polypropylene, polyvinyl chloride.: Because of their chemical resistance, for example to foods, carbonated liquids or the like, polyesters, in particular polyethylene terephthalate, are preferred. Temperature resistance is desired, I prefer hoses made of polyolefins, especially polypropylene.

Stabilizers, carbon black, pore-forming agents 1 or other additives can be added to the empty ones. According to the main patent, the hoses usually have a jacket that does not let liquids through. For the use of thin-walled hoses for filter units, however, it is advantageous if the thin-walled hoses have a microporous jacket. Adjustment of such thin-walled hoses as described above / by melt spinning synthetic poles / whereby the manufacturing process according to the main patent is characterized in that the withdrawal speed!

It can be made clearly visible if, for example, a mono-1 filen polyester thread with a final titer of 100 dtex is drawn off at 370 m / min and the take-off device (rapid winding device I 'or thread injector), which is initially arranged vertically below the I spinneret, gradually in the horizontal direction removes and, if necessary, lifts it in the vertical direction at the same time. 1 Despite the change in the position of the take-off element, the thread below the spinneret continues to move vertically downwards for a certain distance in order to then bend in the direction of the take-off element. The area of this I "natural" i.e. without additional mechanical thread guide organs, the thread deflection is only a few cm long and does not change its position significantly, even if the position of the take-off element is changed significantly. On the other hand, the position of the area of "natural thread bending" can be varied by changing the spinning conditions; for example, it moves away from the spinneret as the melt throughput increases. The phenomenon also occurs when spinning thin-walled tubes. With the help of this phenomenon, the spinning height can be passed through! lateral arrangement of the fume cupboard keep low while] keeping the cool for the fresh || spun threads required cooling section. ;! L \ ILJ '1 ______________ • I A3GW31861 / A · - 9 - If, as already suggested in the main patent, the distance between the take-off element and the area of the natural thread deflection is chosen to be sufficiently large, the hose is subjected to a further delay, stretching two to three times its original length. Although it is not possible to mechanically, i.e., quickly, spin the thin walled hoses in the area of "natural thread bending". To deflect by means of a deflecting element, deflection is achieved by arranging a baffle plate perpendicularly below the spinneret, the region of the "natural thread deflection" being thereby moved closer to the spinneret. The area of "natural thread bending" can also be moved into a cooling liquid, for example by arranging a small water trough instead of the baffle mentioned. To produce stable hose structures with large external dimensions and very small wall thicknesses, as already described in the main patent, a cavity-forming fluid, in particular a gas, is blown into the hose while the thin-walled hose is being spun out of the nozzle. As already mentioned in the main patent, such are suitable: thin-walled hoses spun by rapid spinning, for example for the production of heat exchangers, in which case they generally have a circular cross section and an outer diameter of about 40 to 1000 jam or more, with wall thicknesses of about 5 to 50 jm for Λ / Λ -10 - | i · π \ A3GW31861 / A ·! - ίο - or have more. It has now been found that the specific heat transfer performance of the thin-walled hoses which can also be used in heat transfer devices (heat exchangers) according to the main patent (p 28 41 ~ 091. "5t) can be considerably improved. Such thin-walled hoses produced by a rapid spinning process are particularly suitable then for heat transfer if they have properties and / or a shape which increase their heat conduction and / or their heat transfer, and if they are arranged, using their flexibility, in such a way that the heat transfer devices made from such thin-walled hoses I have a larger size Resistance to external mechanical stresses, so that they guarantee an undiminished heat transfer performance even after prolonged operational use. The present invention is therefore based on the object, the heat conduction, heat transfer and heat transition properties of thin-walled hoses according to main patent f. {ê.W ij (F-28 41— · ·91.5) and to improve one of such hoses || manufactured heat transfer device available to which - in terms of both their manufacture and their use, performance and heat transfer performance - ϊ! does not have the disadvantages of the heat exchanger produced from the known hollow filaments. AI - 11 - j · I— _I i I 'Γ Ί A3GW31861 / A - 11- This object is achieved in that: the thin-walled hoses contain fillers, stabilizers, additives, carbon black, color pigments or the like, and / or the thin-walled Hoses have an essentially circular cross-section and / or the outer diameter of the hoses is in the range from 0.04 to 4 mm, preferably from 0.04 to 1 mm, and / or the wall thickness of the thin-walled hoses is in the range from 5 to 100 pm, in particular from 5 to 50 μm and very particularly from 5 to 20 mm, and / or the thin-walled hoses are profiled on the inside and / or outside and / or the thin-walled hoses have a shape that is constant or discontinuous in their longitudinal direction and / or size may have a periodically changing cross-section and / or. the heat transfer coefficient of the wall of the thin-walled 2 hoses is at least 1500 to at least 4500 w / m K and / or the thin-walled hoses are made from two or more components. -12 -. L J A3GW31861 / A 1 I î * I ”12 - I .: ί | In a device manufactured using such thin-walled hoses, according to the invention, each individual thin-walled hose is preferably the entirety of all thin-walled hoses in the form of regular and / or over the greater part of its length, preferably over its entire length, and / or the greater part of all thin-walled hoses irregular loops arranged. Such a device according to the invention for transferring heat does not have the disadvantages of the known heat exchangers made of hollow fibers, in which the hollow fibers are arranged in a straight line, parallel to one another and at a distance from one another. This known arrangement, as it is also common in metal tube bundle heat exchangers, makes the production of such heat exchangers from hollow fibers difficult and expensive. In addition, with this known arrangement of the hollow fibers, the hollow fiber bundles can be damaged, for example kinked, even by slight external mechanical influences. To increase the heat transfer performance of the device according to the invention, it is particularly advantageous to use thin-walled hoses which are highly heat-conducting substances such as metals, graphite and the like. contained in dust or powder form. The thin-walled hoses can I or additionally fillers, stabilizers, additives, I carbon black, color pigments or the like. contain. The use of microporous thin-walled hoses! allows, when using correspondingly high pressures! / λ! I. J I A3GW31861 / A | In addition to the heat transfer taking place through the wall of the thin-walled hoses, a liquid is additionally cooled in that part of the liquid to be cooled evaporates or evaporates on the surface of the porous thin-walled hoses. The use of the thin-walled hoses spun according to the main patent leads to a heat exchanger with a high heat exchange capacity due to the small wall thickness of the hoses, which can be further increased by the fact that due to the high strength of these hoses, the permissible operating pressure within them and thus the achievable fluid flow rate are relatively large . For the manufacture of the heat exchanger according to the invention, thin-walled hoses with an, for example, elliptical or three, four, five, six, and polygonal cross-section are suitable, but in particular those with a round cross-section, since in one made from thin-walled hoses with a round cross-section Heat exchangers with intersecting thin-walled hoses essentially only touch one another and only a small proportion of the total heat exchange surface is lost through these contact points. The thin-walled hoses can also be profiled on the inside and / or outside. Also, two, three or more thin-walled hoses lying parallel to each other can be lying on their respective contact surfaces, for example by melting, welding, gluing or the like. firmly together Λ - 14- j r π 1 A3GW31861 / A I 4 1. -14 - i 5 - »j *. Also suitable are thin-walled hoses with a cross-section that changes continuously or discontinuously in their longitudinal direction in their shape and / or size, if appropriate periodically. Thin-walled hoses of this type can advantageously influence the mode of operation of the heat exchanger according to the invention in various ways. For example, the inner and / or outer heat transfer surface can be increased, the kink resistance of the thin-walled hoses improved and / or the contact area of the intersecting thin-walled hoses can be reduced by means of thin-walled hoses which are profiled on the inside and / or outside. Furthermore, the heat transfer performance is further increased by the fact that the thin-walled j | Hoses the heat transfer through vortex formation in the respective Fluid is improved. Can also be made from thin-walled! Manufacture hoses with a non-circular cylindrical shape TO some extent more compact and / or dimensionally stable devices. To ensure good heat conduction through the thin-walled hoses, the wall of the hoses should be dimensioned as thin as possible, but still sufficiently thick to meet the mechanical requirements. Thin-walled hoses have proven to be advantageous for most uses, the wall thickness of which is in the range from 5 to 100, with good heat transfer rates being achieved with thin-walled hoses, the wall thickness of which is in the range of 5 to 50 μm, and particularly good with; those whose wall thickness is in the range from 5 to 20 pm. H . _! ; 15. L J Γ π I A3GW31861 / A | - 15- To achieve good heat transfer (k-number), the cross-sections of the thin-walled hoses used should also be dimensioned accordingly. For example, of the thin-walled tubes with a round cross-section, those with an outer diameter in the range from 0.04 to 4 mm, in particular from 0.04 to 1 mm, have proven to be advantageous. In the case of the thin-walled hoses which can be used to produce the heat exchanger according to the invention, the heat transfer coefficient of the wall of the thin-walled hoses should be at least 1500 W / m K, but in particular at least 2 4500 W / m K. The heat transfer coefficient of the wall of the thin-walled hoses is understood here to mean the quotient of the thermal conductivity of the material used for the thin-walled hoses measured in W / m K and the wall thickness of the thin-walled hoses measured in m. The loop-shaped or partially loop-shaped arrangement of the thin-walled hoses in a device according to the invention, which is also referred to as a heat exchanger for simplification in the further description, is achieved in a simple manner according to the invention in particular in that one or more endless thin-walled hoses by means of a winding or rewinding device with one or more thread guide (s) which are moved back and forth parallel to the axis of rotation of the winding device, for example on a perforated tubular bobbin (also called a sleeve or bobbin) and in this way form a single or multi-layer bobbin or winding body. / Λ Λ. L J π π I A3GW31861 / A *; ; -16-; Anordnung ι I This arrangement is particularly advantageous because the thin-walled hoses are in the usable state of the pre | direction have the shape of a spatially expanding helix, the thin-walled tubes being advantageously arranged in several layers in order to achieve an easily flowable and dimensionally stable winding package in such a way that the thin-walled tubes of each layer touch the thin-walled tubes of the adjacent layers, and, if necessary multiple, cross. This arrangement of the thin-walled hoses ensures a large heat transfer area in a small space, since the thin-walled hoses touch each other at the intersection points, but only an insignificant proportion of the heat transfer surface is lost due to the mutual contact of the thin-walled hoses. The bobbin receiving the bobbin or bobbin need not necessarily have a circular cross-section, but the cross-section of the bobbin can for example also be elliptical or a polygon, in particular a rectangle with rounded corners. Likewise, the bobbin used to manufacture the bobbin or bobbin can also be one larger or | along its longitudinal axis have a decreasing cross-section. For example, its outer surface can be conical, diaboloidal, truncated pyramid-shaped with rounded side edges, barrel-shaped, etc., so that the thin-walled tubes wound on such a shaped coil former generally correspond in shape to the shape of the respective coil former. • A -17 - LLJ Î Γ Ί A3GW31861 / A - 17- form bobbin or bobbin. In a further embodiment of the device according to the invention, the thin-walled hoses have the shape of a spiral lying in one plane. The heat exchanger according to the invention can, however, also be produced from one or more flat structures which have been produced by a weaving, knitting, stretching or laying process. Such flat structures can also be produced in a quick and simple manner, like the winding or winding bodies. To produce a heat exchanger according to the invention from a winding or winding body, the two front ends can be measured on a short section, measured in the longitudinal direction of the winding body, for example in a hardenable potting compound such as casting resin, polyurethane and the like. are poured in, the potting compound completely penetrating the winding body in the area mentioned and possibly forming a flange-like attachment outside the winding body, which have a larger circumference than the winding body itself. However, such a (flange-like) attachment can only be used on one of the two end faces of the winding body can be provided. By removing a part of each of these (flange-shaped) end faces into the area of the thin-walled tubes, the arcuate reversal sections of the individual winding core layers lying on the end faces of the winding core are removed and a structure is thus produced from the original winding core, which consists of a large number of in L · "18 -.

It is also possible to produce a heat exchanger according to the invention which allows any number of fluids to participate in L \ - 19 “Γ Ί A3GW31861 / A - 19 - of the heat transfer without the individual fluids being mixed with one another. A heat exchanger according to the invention produced from a winding or winding body can, for example, be equipped such that the inlet openings and the outlet openings for a first fluid are on one end face of the heat exchanger and those for a second fluid are on the other end face of the heat exchanger. For the production of a large number of smaller heat exchangers, it is possible according to the invention to convert the winding or winding bodies or flat structures intended for the production of the heat exchangers in units, i.e. To divide strips, disks or the like, of the desired size, the thin tubes in those areas in which the division is to take place, advantageously beforehand in a suitable manner, for example, as already described, by pouring into casting resin or the like, in their shape and Position can be fixed and their openings can be easily exposed by cutting. In the context of the present invention, it is also possible to cast the thin tubes in a material which is a good conductor of heat, in order in this way to transfer heat from a fluid to the material which is a good conductor of heat or vice versa. A heat exchanger according to the invention designed in this way, which also has, for example, two separate circuits for two fluids to be kept separate from one another, allows heat to be drawn, for example, from the i ^ - 20-.

It is also possible to use such a heat exchanger, for example, to simultaneously transfer the heat aufgenommen absorbed by the B casting body, which is a good conductor of heat, to two fluids, for example by radiation. Wärm "The heat exchanger according to the invention is suitable for solving even the most demanding heat transfer problems, such as beim they can occur, for example, when evaporating or condensing. In particular, the heat exchanger according to the invention is suitable wherever for energy generation i ·; i only comparatively small temperature differences are available, which inevitably make large heat transfer surfaces necessary, which, understandably, must be accommodated in the smallest possible space, because of the favorable corrosion properties of the thin hoses S which can be used for the production of the heat exchanger according to the invention Heat exchanger, in particular for aggressive media, such as acids, bases and the like. With a suitable selection of the thin hoses that can be used, it is possible owing to the known different surface properties of the same I to use the heat exchanger according to the invention forth also for such To use fluids that tend to form deposits on the tube walls in conventional metal tube heat exchangers! 9en * The heat exchanger according to the invention is therefore equally suitable for chemical processes, for energy generation or conversion, in refrigeration technology, in air conditioning technology, in the food industry, for heating homes and work spaces, for I / M -21-, . 1— _J Γ π I A3GW31861 / AI - 21 - Lanä-- | Water and aircraft, in particular as an oil cooler, as a water cooler for dissipating the engine heat or for warming up the fresh air fed into the vehicle interior, as a condenser and as an evaporator, in particular also as Flash evaporator. The heat exchanger according to the invention is very particularly suitable for heat pump devices in which, for example, heat from the ambient air or from the ground is used to heat living rooms, or as a collector of solar heat, such embodiments of the heat exchanger according to the invention having proven particularly useful for this purpose which the thin tubes are arranged in one layer and are also black. The heat exchanger according to the invention is thus suitable for solving most heat transfer problems, i.e. for heat transfer from gaseous fluids to gaseous, from liquid fluids to liquid, from liquid fluids to gaseous and vice versa, from solid substances to gaseous and / or liquid fluids and vice versa, although it should be noted that the temperatures of the substances involved in the heat exchange by the physical and chemical properties of the thin hoses used are limited accordingly. When dimensioning the heat exchanger according to the invention, it should be noted that the smaller the diameter of the thin hoses to be used, the greater the heat transfer area that can be achieved per available volume unit. The amount of heat to be transferred with a constant total flow cross-section of all thin hoses and / Λ'Λ - 22 -. Li J Γ π 1 A3GW31861 / A «-2 2- constant amount of fluid generally also increases; with smaller tube diameters. However, it should be noted that in this case the pressure loss in the thin hoses also increases. It should also be noted that the kink resistance of the thin tubes generally decreases with increasing diameter with the same wall thickness. With suitable selection and dimensioning of the thin j hoses which can be used for the heat exchanger according to the invention, it is possible to achieve specific heat transfer performance which can be better, in some cases considerably better, than that with conventional metal tube heat! exchangeable. The selection of suitable thin hoses should, if possible, be carried out in such a way that the heat transfer resistance through the wall of the thin hoses is essentially negligible compared to the heat transfer resistances occurring inside and outside the thin hoses. This means that thin hoses made of a material with relatively good thermal conductivity properties have a larger wall thickness! as such with very low thermal conductivity values. i I Cross-section of the thin tubes, the bobbin or bobbin or the bobbin is understood in the sense of the invention, the cut surface that is obtained when a thin tube, a bobbin or bobbin or a bobbin on any or specified Intersects perpendicular to its longitudinal or rotational axis. In the case of a round, thin tube, a circular cross section is obtained in this way. In the case of, for example, a coil carrier with a rectangular cross section with h. L J Γ π I A3GW31861 / A I “23. - Rounded corners of wound bobbin or bobbin is by definition a rectangular ring cross-section with rounded corners. For the purposes of the present invention, loop shape is understood to mean any shape deviating from a straight shape, in particular any type of flat or spatial curvature, the radius of curvature being large enough to prevent the thin tubes from buckling. Generally, the radius of curvature is less than 1 m, but it can be larger. To achieve the object on which the present invention is based, it is not necessary for all thin tubes to have a loop shape over their entire length, but it is sufficient if the greater part of the thin tubes is in a loop shape, i.e. if each individual thin tube of the device according to the invention has a loop shape over the greater part of its length and / or if straight and loop-shaped thin tubes are present, as long as the total length of all thin tubes and / or tube pieces in the form of a loop is greater than the total length of all straight tubes and / or hose pieces. This loop shape of the thin hoses ensures that the thin hoses intersect several times at substantially short intervals and support each other in this way, so that each thin hose is generally unsupported only over relatively short length sections, which creates the risk of kinking the thin hoses is significantly reduced. - * -.
