Description

Wärmetauscher für UnterdrucksystemeHeat exchangers for vacuum systems
Dei Erfindung betrifft einen Wärmetauscher, z.B. zum Einsatz als flächiger Solarabsorber bzw. als Dachplatte oder Wandplatte, für den Einsatz in Unterdrucksystemen. Ein Unterdrucksystem besteht z.B. dort, wo das Wärmetauschermedium durch eine Saugpumpe in Umlauf gehalten wird oder wo der Wärmetauscher bei Einsatz einer Druckpumpe so hoch über dem Wärmespeicher gelagert ist, daß in ihm bei entsprechend dosierter Pumpenleistung durch das im Fallrohr hängende Wärmetauschermedium ein Sog erzeugt wird. Der letztere Sachverhalt ist in der Regel bei solaren Wärmetauschern gegeben, wenn diese z.B. auf einem Dach oder an einer anderen erhöhten Stelle montiert sind und der zugehörige Wärmespeicher (mit Druckpumpe) tiefer gelagert ist.The invention relates to a heat exchanger, e.g. for use as a flat solar absorber or as a roof panel or wall panel, for use in vacuum systems. A vacuum system exists e.g. where the heat exchanger medium is kept in circulation by a suction pump or where the heat exchanger is stored so high above the heat accumulator when using a pressure pump that suction is generated in it with the pump power being dosed accordingly by the heat exchanger medium hanging in the downpipe. The latter is usually the case with solar heat exchangers, e.g. are mounted on a roof or at another elevated location and the associated heat accumulator (with pressure pump) is stored lower.
Der Effekt, daß sich bei Unterdruck im Wärmetauscher nicht nur die Zu- und Abflüsse einfacher, z.B. statt durch Verschraubung durch Stöpselung, anschließen lassen und insbesondere, daß als Trennschicht zwischen Wärmetauschermedium und Außenbereich eine flexible HülleThe effect that not only the inflows and outflows are easier with negative pressure in the heat exchanger, e.g. instead of screwing by plugging, and especially that a flexible cover as a separating layer between the heat exchange medium and the outside area
ORIGINALUNTERLA verwendet werden kann, wenn diese an ihrer durch den Unterdruck bedingten Volumenverringerung gehindert wird, wurde bisher für die Konzipierung von Wärmetauschern nicht oder nur unzureichend genutzt.ORIGINAL SUBLA can be used if it is prevented from its volume reduction due to the negative pressure, has so far not been used or was used only insufficiently for the design of heat exchangers.
Der Erfindung liegt die Aufgabe zugrunde, durch besondere Ausgestaltung eines der Kontraktion der Hülle Widerstand leistenden ganz innerhalb oder an der Hülle liegenden Kerns einen einfachen und kostengünstigen Wärmetauscher vorzugsweise als Dachplatte, als Kühlvorrichtung für Dach und Gebäude sowie als solares Brauchwasser-Erwärmungs- bzw. Brauchwasser-Vorwärmungsaggregat zu erhalten.The invention has for its object, through a special design of the contraction of the shell resisting completely inside or on the core lying a simple and inexpensive heat exchanger preferably as a roof plate, as a cooling device for roof and building and as solar hot water heating or hot water - Get the preheater.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Kern auf der für den Wärmetausch vorgesehenen Oberfläche schmale Rillen, Nuten oder Kanäle zur Aufnahme des Wärmetauschermediums aufweist, wobei die Rillen, Nuten oder Kanäle in einen Zu- und Abflußkanal münden.This object is achieved in that the core has narrow grooves, grooves or channels for receiving the heat exchange medium on the surface provided for the heat exchange, the grooves, grooves or channels opening into an inflow and outflow channel.
Nach einer anderen Ausprägung der Erfindung befinden sich die Kanäle bzw. Rillen, Nuten nicht im Kern, sondern in bzw. an der flexiblen Hülle mit dem Vorteil, daß die beiden Stirnseiten stabil ausgestaltet sein können und als solche die Funktionen der aufgeschweißten Platte übernehmen.According to another embodiment of the invention, the channels or grooves, grooves are not in the core, but in or on the flexible sleeve with the advantage that the two end faces can be designed to be stable and as such take over the functions of the welded plate.
Besonders vorteilhaft ist es, wenn die den Kern abdeckende insbesondere ganz umfassende Hülle vorzugsweise aus Kunststoff ist. Eine einfache und dichte Ausgestaltung ergibt sich, wenn die Hülle ein an den beiden Enden verschweißter Schrumnpfschlauch ist.It is particularly advantageous if the sheath covering the core, in particular quite completely, is preferably made of plastic. A simple and tight design results if the sleeve is a shrink tube welded at both ends.
Vorteilhaft ist eine Ausgestaltung des Kerns aus Hartstyropor, Beton oder Keramik. Vorzugsweise wird vorgeschlagen, daß auch die Zu- und Abflußkanäle für das Wärmetauschermedium ebenfalls Rillen oder Nuten sind und daß sämtliche Rillen, Nuten eine wesentlich größere Tiefe als Breite haben, damit die Hülle infolge des Unterdrucks nicht oder nur unwesentlich in die Rillen eindringen und den Durchfluß behindern kann. Durch diese Ausgestaltung des Kerns ist dafür gesorgt, daß die flexible Hülle durch den Unterdruck überall dort fest an den Kern angesaugt wird, wo kein Wärmetausch stattfinden soll und daß das Wärmetauschermedium ausschließlich an den für den Wärmetausch vorgesehenen Innenflächen der Hülle vorbeifließt.An embodiment of the core made of hard polystyrene, concrete or ceramic is advantageous. Preferably It is proposed that the inflow and outflow channels for the heat exchange medium are also grooves or grooves and that all grooves, grooves have a much greater depth than width so that the casing cannot penetrate into the grooves or can only insignificantly penetrate the flow and hinder the flow due to the negative pressure . This configuration of the core ensures that the flexible shell is sucked firmly into the core by the negative pressure wherever no heat exchange is to take place and that the heat exchange medium flows exclusively past the inner surfaces of the shell provided for the heat exchange.
Um den Zu- und Abflußkanal optimal mit den Zu- und Abflußleitungen einfach, kostengünstig und doch dicht zu verbinden, besteht die Zu- und Abflußöffnung aus einer z.B. auf die Hülle aufgeschweißten kleinen Platte, die eine vorzugsweise runde Öffnung für die Einführung des z.B. mit einem Dichtungsschlauchstück versehenen Verbindungsstutzens als Steckverbindung der Zu- bzw. Ableitung hat. Das z.B. aus Gummi oder Silikon bestehende Dichtungsschlauchstück wird durch das Einführen des Verbindungsstutzens in die runde Öffnung der aufgeschweißten Platte so fest eingepreßt, daß die erforderliche luftdichte Verbindung entsteht.In order to connect the inflow and outflow channel optimally with the inflow and outflow lines easily, inexpensively and yet tightly, the inflow and outflow opening consists of e.g. small plate welded onto the casing, which preferably has a round opening for the introduction of e.g. with a piece of sealing hose provided connecting piece as a plug connection of the supply or discharge. That e.g. made of rubber or silicone sealing tube piece is so tightly pressed by inserting the connecting piece into the round opening of the welded plate that the required airtight connection is created.
Speziell für den Einsatz des erfindungsgemäßen Wärmetauschers als solarer Warmwasserbereiter ist die Hülle farblich, vorzugsweise schwarz, sowie weitgehend korrosions- und uv-beständig ausgerüstet. Dazu kann auch eine auf der Wärmetauscherseite aufkaschierte schwarz gefärbte dünne Metallfolie dienen.Especially for the use of the heat exchanger according to the invention as a solar water heater, the shell is preferably colored, preferably black, and largely resistant to corrosion and UV. A black colored thin metal foil laminated on the heat exchanger side can also serve this purpose.

Es zeigen: Figur 1: einen erfindungsgemäßen Wärmetauscher, dessen Kern in eine Kunststoffolie luftdicht eingeschweißt ist, in perspektivischer Darstellung,In the following, the invention is explained in more detail with reference to drawings that show only one variant.

Die durch die Erfindung erreichten Vorteile der Vorrichtung bestehen im wesentlichen darin, daß das Wärmetauschermedium nur durch eine dünne Hülle, z.B. Metall und/oder Kunststoff, vom Wärme abgebenden (bzw. Wärme aufnehmenden) Außenbereich getrennt ist, wodurch der Wärmetauscher als Dachplatte, als Kühlvorrichtung für Dach und Gebäude sowie als solares Brauchwassererwärmungsaggregat eine hohe Effizienz erhält. Die das Wärmetauschermedium aufnehmenden Rillen bzw. Kanäle sind so tief eingefräst, daß die Hülle infolge des Sogs nicht tief in sie hineingezogen wird und sie daher nicht verstopfen kann.The advantages of the device achieved by the invention consist essentially in the fact that the heat exchange medium is separated from the heat-emitting (or heat-absorbing) outer area only by a thin sheath, for example metal and / or plastic, whereby the heat exchanger as a roof plate, as a cooling device for roofs and buildings and as a solar hot water heating unit is highly efficient. The grooves or channels receiving the heat exchange medium are milled so deep that the casing is not drawn deep into it as a result of the suction and therefore cannot clog it.
Die Verwendung einer vorteilhaft gefärbten bzw. beschichteten Hülle, z.B. einer schwarzen, uv-stabilisierten Folie, macht den Wärmetauscher ebenso wie die Verwendung eines Kerns, z.B. aus wärmedämmenden Hartpolystyrolplatten bzw. aus Beton oder Keramik, nicht nur äußerst preisgünstig, sondern auch gut recyclingfähig. Die Kosten-Nutzen-Relation ist besonders vorteilhaft. Die Montage der erfindungsgemäßen Absorber ist, z.B. durch punktuelles Befestigen (z.B. Aufkleben)- auf dem Dach, schnell und kostengünstig durchzuführen. Das rasche Auswechseln bei Beschädigung ist kein Problem. Schließlich ist der erfindungsgemäße Absorber selbst absolut frostbeständig, benötigt im Wärmetauschermedium kein Frostschutzmittel und erfordert, z.B. zur Erwärmung von Brauchwasser, keinen zusätzlichen Wärmetauscher. Als Solarabsorber - auch in Form einer Dachplatte - dient er auf angenehme und rentable Weise zugleich der Abwehr extremer Hitze auf und unter dem Dach sowie der Erwärmung von Schwimmbad¬ oder Duschwasser bis ca. 60 Grad C. The use of an advantageously colored or coated envelope, e.g. a black, UV stabilized foil, makes the heat exchanger as well as the use of a core, e.g. Made of thermally insulating hard polystyrene plates or made of concrete or ceramic, not only extremely inexpensive, but also easily recyclable. The cost-benefit ratio is particularly advantageous. The assembly of the absorbers according to the invention is e.g. by selective fixing (e.g. gluing) - on the roof, quick and inexpensive to carry out. Quick replacement if damaged is not a problem. Finally, the absorber according to the invention is itself absolutely frost-resistant, does not require any antifreeze in the heat exchange medium and requires, e.g. for heating domestic water, no additional heat exchanger. As a solar absorber - also in the form of a roof panel - it serves in a pleasant and profitable way to ward off extreme heat on and under the roof and to heat swimming pool or shower water up to approx. 60 degrees C.
