Claims (2)

<Desc/Clms Page number 1>  <Desc / Clms Page number 1>   Die Erfindung bezieht sich auf einen Adsorber-/Desorber-Wärmetauscher gemäss dem Oberbe- griff des Anspruches 1.  The invention relates to an adsorber / desorber heat exchanger according to the preamble of claim 1. Bei bekannten derartigen Adsorber-/Desorber-Wärmetauschern ist ein Rohr in Granalien ein- gebettet.  In known adsorber / desorber heat exchangers, a tube is embedded in granules. Bei solchen Wärmetauschern ergibt sich der Nachteil, dass aufgrund der schlechten Wärmeleit- fähigkeit des Adsorbens und des hohen Diffusionswiderstandes innerhalb der Schüttung der Sorp- tionsprozess nur sehr langsam und daher uneffektiv abläuft.  The disadvantage of such heat exchangers is that, owing to the poor thermal conductivity of the adsorbent and the high diffusion resistance within the bed, the sorption process is very slow and therefore ineffective. Ziel der Erfindung ist es, diesen Nachteil zu vermeiden und einen Adsober-/Desorber-Wärme- tauscher der eingangs erwähnten Art vorzuschlagen, bei dem ein rascher Ablauf des Sorptions- prozesses sichergestellt ist.  The aim of the invention is to avoid this disadvantage and to propose an adsorber / desorber heat exchanger of the type mentioned at the beginning, in which a rapid course of the sorption process is ensured. Erfindungsgemäss wird dies bei einem Wärmetauscher der eingangs erwähnten Art durch die kennzeichnenden Merkmale des Anspruches 1 erreicht.  According to the invention, this is achieved in a heat exchanger of the type mentioned at the outset by the characterizing features of claim 1. Durch die vorgeschlagenen Massnahmen wird erreicht, dass einerseits die Wärmetauschfläche des Rohres vergrössert wird und zwischen den einzelnen Rippen nur eine einlagige Schüttung möglich ist. Dadurch kann der Sorptionsprozess trotz der schlechten Wärmeleitfähigkeit und trotz des grossen Diffusionswiderstandes des Adsorbens schnell und effektiv ablaufen. Dabei liegt eine grosse Stoffaustauschfläche für die Adsorption und Desorption des Adsorbats, z. B. Wasser, vor und die Wärme kann durch den direkten Kontakt zur Rippe schnell mit dem Wärmeträger, der im Rohr strömt, ausgetauscht werden.  The proposed measures ensure that, on the one hand, the heat exchange surface of the pipe is increased and that only a single-layer fill is possible between the individual fins. As a result, the sorption process can run quickly and effectively despite the poor thermal conductivity and despite the high diffusion resistance of the adsorbent. There is a large mass transfer area for the adsorption and desorption of the adsorbate, e.g. B. water, and the heat can be quickly exchanged through direct contact with the rib with the heat transfer medium flowing in the tube. Durch die vorgeschlagenen Massnahmen wird auch eine hohe Wärmeziffer der Sorptions- wärmepumpe bei gleichzeitig guter Leistungsdichte erreicht.  The proposed measures also achieve a high heat coefficient of the sorption heat pump with a good power density. In diesem Zusammenhang ist es vorteilhaft die Merkmale des Anspruches 2 vorzusehen.  In this context, it is advantageous to provide the features of claim 2. Durch die Merkmale des Anspruches 3 ist eine sehr einfache Herstellung eines erfindungs- gemässen Adsorber-/Desorber-Wärmetauschers ermöglicht.  The features of claim 3 enable a very simple manufacture of an adsorber / desorber heat exchanger according to the invention. Die Erfindung wird nun anhand der Zeichnung näher erläutert, die schematisch einen erfin- dungsgemässen Wärmetauscher zeigt.  The invention will now be explained in more detail with reference to the drawing, which schematically shows a heat exchanger according to the invention. Der dargestellte Adsorber-/Desorber-Wärmetauscher weist ein von einem wärmeaufnehmen- den Medium durchströmbares Rohr 1 auf. Dieses Rohr 1 ist mit Rippen 2 versehen und steht mit diesen in einer gut wärmeleitenden Verbindung.  The adsorber / desorber heat exchanger shown has a tube 1 through which a heat-absorbing medium can flow. This tube 1 is provided with ribs 2 and is in a good heat-conducting connection with them. Zwischen den einzelnen Rippen 2 sind Granalien 4 in jeweils einer Lage eingebracht, wobei die Korngrösse der Granalien geringfügig kleiner als der lichte Abstand 5 zweier Rippen ist. Dadurch ist sichergestellt, dass sich zwischen je zwei Rippen 2 lediglich eine Lage von Granalien befindet, wobei es sich vorteilhafterweise um einen Zeolith handelt.  Granules 4 are placed in each layer between the individual ribs 2, the grain size of the granules being slightly smaller than the clear spacing 5 between two ribs. This ensures that there is only one layer of granules between each two ribs 2, which is advantageously a zeolite. Im Bereich der Rippen 2 ist der Wärmetauscher von einem Netz 3 umgeben, das das Heraus- fallen der Granalien 4 verhindert. Zur Sicherung des Netzes 3 ist dieses mit einem Band 6 um- wickelt PATENTANSPRÜCHE: 1. Adsorber-/Desorber-Wärmetauscher mit einem von Granalien (4) umgebenen von einem wärmeaufnehmenden Medium durchströmbaren Rohr (1), dadurch gekennzeichnet, dass das Rohr (1) mit Rippen (2) versehen ist, die einen Abstand voneinander aufweisen, der kleiner als die doppelte Korngrösse der Granalien (4), z. B. eines Zeolithen, ist, und der Raum zwischen den Rippen (2) mit einlagig eingebrachten Granalien (4) ausgefüllt ist, wobei die Rippen (2) von einem Netz (3) umgeben sind.  In the area of the fins 2, the heat exchanger is surrounded by a network 3 which prevents the granules 4 from falling out. To secure the network 3, it is wrapped with a tape 6 PATENT CLAIMS: 1. adsorber / desorber heat exchanger with a tube (1) surrounded by granules (4) through which a heat-absorbing medium can flow, characterized in that the tube (1) is provided with ribs (2) which are at a distance from one another smaller than twice the grain size of the granules (4), e.g. B. a zeolite, and Space between the ribs (2) is filled with single-layer granules (4), the ribs (2) being surrounded by a net (3). 2. Wärmetauscher nach Anspruch 1, dadurch gekennzeichnet, dass die Höhe der Rippen (4) dem drei- bis fünffachen des Rippenabstands entspricht. **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**.  2. Heat exchanger according to claim 1, characterized in that the height of the ribs (4) corresponds to three to five times the rib spacing. ** WARNING ** End of CLMS field knows overlap beginning of DESC **.
