Description

Detailed Description of the Invention The object of the original invention, Japanese Patent Application No. 116335/1983, is to transfer heat from a first fluid to a second fluid through the walls of hollow fibers, and to transfer heat from a first fluid to a second fluid through the walls of hollow fibers, and to It is open and has a connection for fluid supply or fluid discharge, in which the skeleton may be constructed as a supporting frame, and the end section of the hollow fiber is connected to the skeleton outwardly in a fluid-tight manner by means of a joining material.・
The present invention also relates to a device for transferring heat through a hollow fiber, characterized in that at least a portion of the hollow fiber is continuously curved or bent at least once.

For example, the device comprises a gaseous medium flowing around the hollow fibers;
For example, they are suitable for heat transfer between air and a liquid medium flowing in the hollow fibers, such as water, even at particularly high wind speeds and ensure an approximately uniform heat transfer coefficient even when the wind direction changes. In this case, the hollow fibers may be configured, for example, in a circular arc shape, or
It may be bent over or over several times, extended in a zigzag manner or similarly configured. It is important that at least some, preferably all, of the hollow fibers do not run in a straight line, but that they change direction at least once.

Assuming that both ends of each hollow fiber of the device according to the original invention configured as described above are connected by a straight line segment (chord), and the maximum distance from this connecting straight line (chord) to the hollow fiber is defined as the maximum deviation distance. Particularly good results can be obtained when the maximum deflection distance of the hollow fibers of the device is between the two ends of each hollow fiber, that is, the length of the connecting straight line (chord) is /2° to about 14°, especially about 14°. .

The number of hollow fibers in the thread groups forming the heat transfer surface of the device according to the invention can be selected arbitrarily, with the hollow fibers in each thread group having the same or similar shape, if desired. Although not necessarily, they generally have the same or similar shape.

The hollow fibers are arranged not in one plane, but in a spatially arched plane, so that they can be used, for example, on the surface of a hemispherical cap, on the side of a cylinder, on a roof, on a ram, an accordion, a pyramidal trapezoid, etc. Particularly good results are obtained with the shape of a part.

In one embodiment of the invention, the hollow fibers can be arranged in several clusters one above the other, each cluster consisting in particular of one or two hollow fiber layers. In this case, it is advantageous if the hollow fibers of a layer are arranged with equal spacing from each other, but they may also spread out in a fan-shaped manner. The number of hollow fibers may vary from layer to layer. In order that the most advantageous embodiment of such a hollow fiber layer is always obtained, the arrangement of the hollow fibers of such a hollow fiber waste in all cases can also be expressed as the hollow fibers being provided in a broad sense parallel to each other. Do it like this. In the case of two hollow fiber layers per hollow fiber layer, the hollow fibers of the first layer intersect with the hollow fibers of the second layer, and these are in contact at the intersection points. In the case of several hollow fiber layers, it is advantageous to arrange them with a sufficient distance between them, which can be determined by simple experimentation.

In this case, each hollow fiber layer or hollow fiber layer preferably has its own distribution or collection pipe for fluid supply or fluid discharge, which is optionally designed as a supporting frame, and these are common. Connected to inflow or outflow conduits. Particularly advantageously, hollow fiber layers or hollow fiber layers of this kind constructed according to the invention, including their distribution pipes and collection pipes, can be constructed as modular units, with any number of modular units one above the other or one above the other. Can be arranged in parallel. In this case, it is particularly advantageous if the common inflow and outflow conduits are constituted by mutually cooperating pipe pieces or connections in the form of bayonet connections arranged in the distribution or collection pipes. . This bayonet connection can be designed to be removable and self-sealing, or it can also be connected non-removably or liquid-tightly to the outside after the module units have been joined by welding, gluing or the like. The stacked embodiment of the device formed in this way has a square, rectangular, hexagonal, circular or any other shaped cross-section, or the bottom surface, viewed in plan, corresponds exactly to said shape.

In this case, the hollow fiber layers or hollow fiber layers may be connected individually or in groups in series or in parallel, and a mixed type is also possible; for example, the hollow fiber layers of the hollow fiber layers may be connected in parallel. The hollow fiber layers are connected in series.

The hollow fiber scraps or hollow fiber layers arranged one above the other or in parallel can be curved in the same direction, but can also be curved alternately in opposite directions, for example in a mirror image manner. Two oppositely curved hollow fiber layers or hollow fiber layers, the ends of which are located in one blood vessel, may form the shape of, for example, a cushion, a lens, a cylinder, a sphere, etc. in a bottom-overlapping arrangement.

The advantageous shape and arrangement of the hollow fiber layers or hollow fiber layers constituting the device according to the invention, which can readily be determined by simple experiments, keeps the draft noise generated when flowing around the hollow fibers low and therefore A device with less noise that does not damage the environment can be obtained.

The formation of the hollow fiber layers or hollow fiber layers is achieved by correspondingly forming the distribution or collection tubes and/or the supporting rods which also provide great dimensional stability to the hollow fiber groups. Advantageously, these support rods are arranged in such a way that they intersect at least one of the hollow fiber scraps and are firmly connected to the hollow fibers at the point of contact by welding, gluing or the like. It is advantageous if the supporting rods have a larger diameter than the hollow fibers and are arranged at a greater distance from each other than the hollow fibers. The end of the support rod is fixedly connected to the distribution or collection tube. The supporting rod can already be preformed before installation or can be a correspondingly long rod stretched in the form of an arc when installed, for example, between two distribution or collection pipes.

All hollow fibers suitable for heat transfer can be used in producing the device according to the invention, which may be produced by dry or wet spinning methods or extrusion methods. In the original invention, the term hollow fiber includes so-called hollow fibers, thin tubes, thin-walled tubes, capillaries, small tubes, plastic tubes, etc. In general, embodiments of the device according to the invention with non-metallic hollow fibers are preferred, but they can also be readily adapted to devices with corresponding metallic tubules.

The cross-sectional shape of the hollow fibers used may be arbitrary, and there is no upper or lower limit to the cross-sectional size of the hollow fibers or to their wall thickness.

Furthermore, the cross-sectional shape, wall thickness and cross-sectional size of the hollow fibers may vary along the length of the hollow fibers. For example, hollow fibers of circular cross-section may have an outer diameter of 800 μm''5 mm and more. For example, the wall thickness of the hollow fibers may be between 30 and 200 μm.

In particular, in manufacturing the device according to the original invention, range 15 to
Hollow fibers with heat transfer coefficients of 200 W/rr + 2 K and above have proven to be particularly advantageous, optionally with improved heat transfer properties by the introduction of metals in finely divided or powdered form, dalphite, etc. Hollow fibers can also be used. The hollow fibers may optionally or additionally contain fillers, adducts, stabilizers, cardan black, colorants, etc. Advantageously, the range of use of the device according to the invention can be further expanded by using porous or microporous hollow fibers.

To join the ends of the hollow fibers, conventional adhesives, hardening sealing compounds, casting resins, special cements, etc. can be used, and the hollow fibers can be superficially bonded immediately after first contact with the hollow fibers. Bonding materials that are lightly etched or melted can also be used. The joining of hollow fibers or their end sections is known and need not be described in detail.The size of the device according to the invention is not limited within the range of customary dimensions.

It has become clear that when hollow fibers are provided at narrow intervals, the flow resistance of the fluid flowing around the hollow fibers increases, resulting in a decrease in heat transfer efficiency. Very large spacings between the hollow fibers result in unnecessarily large dimensions of the device according to the invention. Therefore, for a particularly advantageous embodiment of the device according to the original invention, the average spacing between two adjacent hollow fibers is from 1.7 to 10 times, in particular from 2.5 to 3.3 times, their diameter. It is suggested that you choose as follows. In this case, it is advantageous if the inner distance between two adjacent hollow fibers is between 0.5 and 15 mm, in particular between 1 and 10 mm.

The dimensions of the distribution or collection tube are determined by the number and size of the hollow fibers protruding from or opening into the tube, and by the total amount of fluid still flowing through the hollow fibers. This is because unnecessarily high pressure losses in the distribution and collection pipes are undesirable. Furthermore,
The dimensions of the distribution and collection pipes are determined by their simultaneous use as a support frame and whether they confer stability commensurate with the due requirements of the device according to the original invention, or whether stability can be achieved by other structural means and Depends on what is provided by the device. Therefore, depending on the requirements for the distribution or collection pipe, it is also possible to provide it with reinforcing ribs, for example, which extend in its longitudinal direction. The same result can also be achieved by providing the tube with a flow-technically advantageous shape or by covering it accordingly.

Furthermore, within the scope of the original invention, the hollow fibers may be suspended in a loose tube shape as a group of threads between the distribution tube and the collection tube, but in this case too, the hollow fibers may be suspended in a loose tube shape to maintain the same hollow fiber spacing. In contrast, transverse rods can also be provided, which are fixedly connected to the hollow fibers at the points of intersection.

In addition to hollow fiber gaps formed from a single hollow fiber layer, suitable hollow fiber gaps can also be formed by hollow fiber fabric. It is also possible to use a hollow fiber mat in which the intervals between the hollow fibers are fixed by woven threads, adhesive strips, or the like.

The invention provides, however, an outwardly liquid-tight connection between the end section of the hollow fiber according to the original invention and a distribution pipe or collection pipe, as well as several parts according to the original invention, optionally constructed in modular form. By improving the outwardly liquid-tight bayonet joints of the sump that joins the units, the desired coupling is achieved more quickly and easily, with greater reliability and more efficiently than with the means proposed by the original invention. It is based on the problem of achieving long-term durability.

According to the invention, an outwardly liquid-tight connection between the end section of the hollow fiber and the distribution or collection tube is improved, in which the end section of the hollow fiber is placed in a backing strip with a corresponding cutout. arranged and fluid-tightly connected outwardly with the strip, and the marking strip is optionally partially inserted into the distribution or collection pipe, in any case with the skeleton. In an embodiment achieved by an outwardly liquid-tight fixed connection, each . is extremely simplified. In this case, the recesses provided in the support recesses of the hollow fiber end regions are, for example, provided in each half in both parts of the marking strip and are hemispherically shaped.

In the case of a ξ-tipping strip constructed in this way, its assembly can be carried out, for example, as follows: First, one of the two parts of the ξ-tightening strip is placed on a workbench with the notch facing up. , and the notch is completely or partially filled with a curable synthetic resin, adhesive, etc. The respective hollow fiber end sections are then pushed into the filled recesses. The cut-out of the hemispherical structure of the second part of the ξ-noting strip is then likewise fully or partially filled with adhesive sealing material and then placed in a similar manner with the cut-out facing downwards. . - The two outwardly liquid-tight members of the ξ binding strip can be joined together by welding, gluing, or the like. Finally, inserting the ξ coupling strip with the hollow fiber end section embedded therein into a distribution or collection tube with a correspondingly dimensioned long slit;
It is fixedly connected to the skeleton in an outwardly liquid-tight manner, and this can be done by welding, gluing, etc.

Furthermore, both parts of the notching strip are provided with cooperating key-and-keyway-like devices or interlocking mechanisms, or their assembly is thereby simplified and the arrangement of the two parts meshes uniquely with each other. It may be formed as follows.

Thus, for example, both parts may have an L-shaped cross-section and be designed in such a way that in their joined state they essentially form a square.

If the hollow fibers and the threading strips are made of the same material, an outwardly liquid-tight connection between them can also be achieved, for example, by ultrasonic welding or hot tool welding.

In the case of rollable hollow fiber mats, the binding strip preferably consists of a rubber-elastic material. This is because in this case, advantageously, the distribution tube or the collection tube is also made of such material in order to make it possible to wind up the hollow fiber mat. In a further particularly advantageous embodiment, these parts can then be integrated in such a way that they essentially form a continuous unit.

The improvement of the bayonet connection, the purpose of which has already been explained in more detail and is fluid-tight against external forces of 1 mm, is achieved according to the invention by means of a connecting element inserted into the connecting tube. The member has at least two annular grooves on its circumferential surface for supporting type 0 bucking or other bucking. This coupling element may be of tubular design if it is to ensure fluid flow, whereas it may be solid if it thereby creates a blockage.
