Abstract

Adsorber/desorber heat exchanger has a tube with ribs surrounded by granulated metal. - DETAILED DESCRIPTION - A heat-receiving medium flows through the tube. The ribs are spaced at a distance from each other which is smaller than the doubled grain sizes of the granulated metal. The space between the ribs is filled with one layer of granulated metal with the ribs surrounded by a net.

Description

Die Erfindung bezieht sich auf einen Adsorber-/Desorber-Wärmetauscher gemäß dem Oberbegriff 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 eingebettet.In known adsorber / desorber heat exchangers, there is a tube in granules embedded.

Bei solchen Wärmetauschern ergibt sich der Nachteil, daß aufgrund der schlechten Wärmeleitfähigkeit des Adsorbens und des hohen Diffusionswiderstandes innerhalb der Schüttung der Sorptionsprozeß nur sehr langsam und daher uneffektiv abläuft.The disadvantage of such heat exchangers is that due to the poor Thermal conductivity of the adsorbent and the high diffusion resistance within the The sorption process is very slow and therefore ineffective.

Ziel der Erfindung ist es, diesen Nachteil zu vermeiden und einen Adsober-/Desorber- Wärmetauscher der eingangs erwähnten Art vorzuschlagen, bei dem ein rascher Ablauf des Sorptionsprozeßes sichergestellt ist.The aim of the invention is to avoid this disadvantage and to have an adsorber / desorber To propose heat exchanger of the type mentioned, 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 in a heat exchanger of the type mentioned by characteristic features of claim 1 achieved.

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 area of the tube is increased and between the individual fins only  a single-layer filling is possible. This allows the sorption process despite the poor thermal conductivity and despite the large diffusion resistance of the adsorbent run quickly and effectively. There is a large mass transfer area for adsorption and desorption of the adsorbate, e.g. B. water, and the heat can be directly Contact with the fin can be quickly exchanged with the heat transfer medium that flows in the pipe.

Durch die vorgeschlagenen Maßnahmen wird auch eine hohe Wärmeziffer der Sorptionswärmepumpe bei gleichzeitig guter Leistungsdichte erreicht.The proposed measures will also have a high heat coefficient Sorption heat pump with good power density achieved.

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 erfindungsgemäßen Adsorber-/Desorber-Wärmetauschers ermöglicht.Due to the features of claim 3, a very simple manufacture of a Adsorber / desorber heat exchanger according to the invention enables.

Die Erfindung wird nun anhand der Zeichnung näher erläutert, die schematisch einen erfindungsgemäßen Wärmetauscher zeigt.The invention will now be explained in more detail with reference to the drawing, which schematically shows a shows heat exchanger according to the invention.

Der dargestellte Adsorber-/Desorber-Wärmetauscher weist ein von einem wärmeaufnehmenden 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 inserted in one 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 Herausfallen der Granalien 4 verhindert. Zur Sicherung des Netzes 3 ist dieses mit einem Band 6 umwickelt.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 , this is wrapped with a tape 6 .
