Verfahren und Vorrichtung zur Dämpfung der in Flüssigkeitserhitzern., welche nach dem Vakuumverdampfungsprinzip arbeiten, auftretenden Geräuschbildung
Zusatz zp Patent.... (Patentanmeldung P 22 17 7**3.l) Method and device for damping the noise generated in liquid heaters, which work according to the vacuum evaporation principle
Addition zp patent .... (patent application P 22 17 7 ** 3.l)

Gegenstand des Hauptpatentes (Patentanmeldung P 22 17
ist:Subject of the main patent (patent application P 22 17
is:

a) ein Verfahren zur Dämpfung der in Flüssigkeitserhitzern, welche nach dem Vakuumverdampfungsprinzip arbeiten, infolge starker Dämpferwicklung an den Heizflächen auftretenden Geräuschbildung, welches dadurch gekennzeichnet ist, dass der Bildung von Dampfblasen in der Heizflüssigkeit durch Staumittel entgegengewirkt wird; unda) a method for damping the in liquid heaters, which work according to the vacuum evaporation principle, as a result of strong damper winding on the heating surfaces, which is characterized in that the formation of vapor bubbles in the heating fluid by means of retaining means is counteracted; and

b) eine Vorrichtung zur Ausführung dieses Verfahrens,
welche dadurch gekennzeichnet ist, dass im Vakuumbehälter
in der Heizflüssigkeit der Dampfblasenbildung entgegen-,
wirkende Staumittel angeordnet sind.b) a device for carrying out this process,
which is characterized in that in the vacuum container
counteract the formation of vapor bubbles in the heating fluid,
acting stowage means are arranged.

Es wurde nun gefunden, dass der Effekt der Geräuschdämpfung beim Verfahren und der Vorrichtung nach dem Hauptpatent
dadurch weiter verbessert werden kann, dass man als Staumittel einen kompakten aber porösen Körper verwendet,
welcher den Vakuumbehälter mindestens bis annähernd zur
Oberfläche der Heizflüssigkeit hinauf, vorzugsweise bis über diese Oberfläche hinauf ausfüllt.It has now been found that the effect of noise reduction in the method and device according to the main patent
can be further improved by using a compact but porous body as the stowage means,
which the vacuum container at least up to approximately
Surface of the heating fluid up, preferably fills up over this surface.

Als kompakte, poröse Körper eignen sich insbesondere: Keramiksinterkörper; metallische Sinterkörper; Formkörper aus porösem Naturstein, wie Tuff; Sinterkörper aus Kunststoffen, welche bei den Betriebstemperaturen gegenüber der Heizflüssigkeit beständig sind, z.B. Polytetrafluoräthylen; Kunststoffschäume, welche bei -den Betriebstemperaturen gegenüber der Heizflüssigkeit beständig sind; Formkörper aus Glasfasern, welche mittels eines bei den Betriebstemperaturen gegenüber der Heizflüssigkeit beständigen Bindemittel miteinander verklebt sind.Particularly suitable compact, porous bodies are: ceramic sintered bodies; metallic sintered bodies; Moldings made of porous natural stone, such as tuff; Sintered body made of plastics, which at operating temperatures are resistant to the heating fluid, e.g. polytetrafluoroethylene; Plastic foams, which at -the operating temperatures are resistant to the heating fluid; Molded body made of glass fibers, which by means of a at the Operating temperatures against the heating fluid resistant binders are glued together.

Bei der Fabrikation der erfindungsgemässen Vorrichtung kann der kompakte, poröse Körper entweder als vorgefertigter Formkörper in den Vakuumbehälter eingebracht werden, oder aber er kann im Vakuumbehälter i_n situ durch Sintern, Verkleben oder Aufschäumen der entsprechenden Rohmaterialien gebildet werden. Die letztgenannte Herstellungsweise hat den Vorteil, dass automatisch ein Körper der gewünschten Abmessungen entsteht, so dass keinerlei Nachbearbeitung notwendig ist.In the manufacture of the device according to the invention, the compact, porous body can either be introduced into the vacuum container as a prefabricated molded body, or it can be formed in situ in the vacuum container by sintering, gluing or foaming the corresponding raw materials. The latter manufacturing method has the advantage that a body of the desired dimensions is automatically created so that no post-processing is necessary.

Im Vergleich zu anderen, kleinteiligen Staumitteln weisen derartige kompakte Körper den Vorteil auf, dass sie auch beim Transport im Vakuumbehälter an Ort bleiben, so dass die erfindungsgemässen Vorrichtungen in .der Fabrik fertiggestellt und anschliessend ohne besondere Vorsichtsmassnahmen transportiert werden können.Compared to other, small-scale stowage means, such compact bodies have the advantage that they also Remain in place during transport in the vacuum container, so that the devices according to the invention are completed in the factory and can then be transported without special precautionary measures.
