(54) A METHOD AND AN APPARATUS FOR MANUFACTURE
OF CYLINDRICAL ROTOR STRUCTURES FOR MOISTURE
AND/OR HEAT EXCHANGERS
(71) We, AKSEBOLAGET CARL
MUNTERS, a Swedish Company, of Industrivagen 2 S-191 47 Sollentuna, Sweden, do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement::- This invention relates to a method of manufacturing a rotor for a moisture and/ or heat exchanger having a moisture and/ or heat exchanging mass composed of alternately plane and corrugated layers with the corrugations extending substantially axially to form a large number of axial, fine channels, and in which method the rotor is built up by alternately plane and corrugated layers being assembled and fixed together and thereafter wound up to a substantially cylindrical rotor structure.
In the manufacture of rotors by the method outlined above the fixing together of the layers is effected by applying glue preferably to the corrugation ridges of the corrugated layer before the corrugated and the plane layers are brought together to be combined by gluing to a coherent strip
Also the fixing together of the turns of winding of the rotor is effected by gluing.
The glue type which is used has a relatively long duration of hardening or solidification of up to 24 hours. This causes problems in the manufacture of the rotor, since an undesirable displacement easily may occur between the layers. This holds true especially when the layers are made of aluminium and are very thin, such as less than 100 microns, since the displacement which is due to stretching of the layers results in deviations from the desired geometric form for the finished rotor structure, especially the fine channels thereof.
Also transportation and storage of the rotor is rendered difficult or impossible during the hardening or solidification duration of the glue.
According to the present invention there is provided a method of producing a rotor for a moisture and/or heat exchanger from a strip of superposed flat and corrugated sheet material which is wound into a cellular structure composed of alternating flat and corrugated layers defining a plurality channels through which streams of fluid media are passed in moisture and/or heat exchange with one another, characterized by the steps of advancing continuously a first flat strip of sheet material between a pair of corrugating rollers to a winding station; applying at least one line of rapidly hardening adhesive across the ridges of the resultant corrugations; applying a line of slow hardening adhesive along each side of the line or lines of rapidly hardening adhesive, advancing continuously a secod flat strip of sheet material into contact with the thus adhesive treated corrugations of the first sheet to cause said flat strip to adhere upon contact along the line or lines of rapidly hardening adhesive to form an initially stabilized by-layered strip.
The invention also included apparatus for carrying out the above metho4 comprising means for producing a rotor for a moisture and/or heat exchanger from a strip of superposed flat and corrugated sheet material which is wound into a cellular structure composed of alternating flat and corrugated layers defining a plurality of channels through which streams of fluid media are passed in moisture and/or heat exchange with one another, the apparatus comprising means for continuously advancing a first strip of sheet material from a supply source between a pair of intermeshing corrugating rollers to a winding station; means for applying at least one line of rapidly hardening adhesive across the ridges of the resultant cormgations; means for applying a line of slow hardening adhesive along each side of the line or lines of rapidly hardening adhesive; means for continuously advancing a second flat strip of sheet material from a supply source to said winding station in contact with the thus adhesive treated corrugations to cause the second strip to adhere along the line or lines rapidly hardening adhesive to form an initially stabilized bi-layered strip while allowing the lines of slow hardening adhesive to harden and form a pair of bonding surfaces spaced from one another by the solidified directly hardening zone during the further advancement to the winding station.
The invention will now be described by way of example with reference to the accompanying drawings in which:
Figure 1 shows a diagrammatic side view of the preferred apparatus for carrying out the method;
Figure 2 is a view according to line II-II in Figure 1.
Referring now to the drawings and especially the embodiment shown in Fig.
1, two thin sheets or webs 10, 12 are unrolled from storage rolls 11 and 13, respectively. The thin sheets 10, 12 of which the rotor is to be manufactured, may in the illustrated embodiment be of metal, such as aluminium, or some suitable plastic material, but may be of other material, such as asbestos or cellulose paper, or other similar materials with which the afore-mentioned problems may arise. If the rotor shall serve for transfer of moisture the webs may be impregnated or provided with a hygro scopic substance, such as lithium chloride, or a solid sorption agent. One of the webs, in the shown example the web or sheet 12, is folded or corrugated so as later on together with the plane sheet to form the channels of the finished rotor.These channels are formed between the corrugated thin sheets and the plane ones and the spacing between the turns of winding of the plane web in the finished rotor is usually less than 3 -mms, amounting for example to between 1 and 2 mms, which defines the vertical height of the corrugations.
The thin sheet 12 unrolled from the roll 13 is fed over a pulley cylinder 14a to a cylinder 14 formed with grooves extending in parallel with the shaft of said cylinder which cooperates with a cylinder 15 which is formed with similar grooves. The cylinders 14, 15 are positioned relatively to one another so that the projections of the one cylinder mesh with the grooves of the cooperating other cylinder with the web or thin sheet 12 interposed therebetween. In this way the thin sheet 12 will be folded when it passes through the nip between the cylinders 14 and 15.After the corrugating step the now shaped thin sheet 12 follows with and about the circumference of the cylinder 15 to the top portion thereof where it meets tie plane thin sheet 10 fed from the storage roller 11 over a pulley cylinder 16 and a thrust roller 17 the base portion of which is in contact with the cylinder 15 through the interposed thin sheets 10, 12.
The webs or thin sheets 10, 12 when being assembled shall be joined together to form a coherent strip 18. This is effected by applying glue to the corrugation ridges on that side of the corrugated web 12 which will meet the plane web 10 at the nip between the cylinders 15, 17.
After a coherent strip 18 has been assembled the sheets or webs may be exposed to a traction in the apparatus.
especially when the rotor is built up by winding the strip 18 about a horizontally disposed hub. Previously there has been a danger that the sheets will be stretched, especially very thin sheets, and this may result in the corrugated sheet being extended so that the height of the corrugation is correspondingly reduced and/or the corrugrations are imparted a defective form.
In order to eliminate this risk there is applied, according to the invention, firstly a glue which substantially instantaneously binds the layers to one another, and secondly a slowly hardening glue which solidifies gradually and imparts to the rotor the necessary mechanical strength for the intended use, which strength cannot be produced by any known type of directly sticking glue. The first glue imparts provisionally to the rotor structure the strength necesary for manufacture proper of the rotor, transportation from the place of manufacture and storage. The first glue may in this connection be of the hotmelt adhesive type, i.e. it is melt or liquid in warm state, but solidifies directly on contact with a cold surface, such as the aluminium or plastic sheets forming the rotor. The other glue imparting to the finished rotor the required mechanical strength may, for example, be a waterbased thermosetting glue which usually has a setting time of about 24 hours.
The hotmelt glue is applied by means of a cylinder 19, the base part of which dips down into a glue vat 20 below the glue surface of the glue contained in the same.
Inserted into the glue vat 20 is a heating coil 21 with connection 22 for keeping the glue at a predetermined increased temperature. The circumference of the cylinder 19 bears with an upper portion against a portion of the circumference of the corrugated cylinder 15 covered by the corrugated thin sheet 12 so that the hotmelt glue is applied to the thin sheet on that side which shortly thereafter will meet the plane thin sheet 10 (see also Fig. 2). The hotmelt glue is applied to a part only of of the corrugated layer 12, in the shown embodiment on the central portion thereof, whereas on either side of the hotmelt glue layer at the edges of the layer 12 two glue strands of the thermosetting glue are applied by means of two cylinders or wheels 23, 24.These cylinders dip with their base portion down into glue troughs 25, 26 while they with an upper portion of the circumference bear against a portion of the cylinder 15 over which the corrugated thin sheet is carried.
In this way the plane thin sheets 10 and the corrugated thin sheets 12 when meeting one another are instantaneously given a directly fixed position relative one another, since the hotmelt glue gets cold and solidifies almost instantaneously on contact with the thin sheets which thereafter cannot be dislodged relatively to one another in the following treatment of the composed strip 18. The thermosetting glue imparts after solidification required mechanical strength to the finished rotor as has been described hereinbefore. By carrying out the gluing operation in the described manner with double gluing cylinders 23, 24 and one gluing cylinder 19 which are positioned on different levels three points of pressure against the thin sheet 12 are obtained which is advantageous from the viewpoint of manufacturing.The corrugated thin sheet which follows around with a portion of the circumference of the cylinder 15 normally tends to rise from the cylinder which tendency hitherto has been counteracted by guide rails or fingers (not shown) arranged behind said portion of the circumference of the cylinder and retaining the corrugated thin sheet in the grooves of the cylinder. However, because of the broad gluing zones proposed herein these fingers or guide rails tend to hinder manufacture by glue sticking to and forming clods on the fingers or guide rails and, therefore due to the preferred disposition of the cylinders 19, 23, 24, the fingers or rails can be omitted, the three cylinders having proved to be sufficient for retaining the corrugated layer tightly on the cylinder 15.In order to ensure the solidification of the hotmelt glue there may be provided downstream of the cylinders 15, 17 a cooling zone as indicated by the cooling device 27 shown in broken lines. The cooling device is operated with cold air or a like agent to cool the plane sheet 10. However, this device is optional, since the hotmelt glue has prover normally to be sufficiently cooled for becoming solidified on contact with the cold webs of thin sheet material.
After the gluing step the composed strip 18 is guided over a pulley cylinder 28 and a cylinder 29 at the underside of which a gluing cylinder 30, which is immersed into a glue vat 31, applies glue on the corrugated side of the strip 18. As the strip 18 is much stronger than the individual sheets 10, 12 and the form of the channels is fixed, the previously mentioned stretching problems occurring in the winding up operation of the strip to obtain the desired cylindrical rotor structure is no longer as harmful as before nor can it have any harmful effect on the corrugations. For this reason the gluing of the rotor when the corrugated and the plane free surfaces of the composed strip 18 meet one another can be effected solely with thermosetting glue of the same kind as is applied by the cylinders 23, 24, i.e. that glue which imparts to the finished rotor its mechanical strength.However, it will be understood that, if it should prove desirable or necessary, this gluing step can be effected in the same manner as with the cylinder 19, 23, 24. The winding up of the rotor is effected in a manner known in the art, for which reason it is not shown or described here in more detail.
