GEHÄUSE ZUR AUFNAHME VON FEUCHTIGKEITSEMPFINDLICHEN HOUSING FOR RECEIVING MOISTURE SENSITIVITY
GEGENSTÄNDEN Die Erfindung betrifft ein Gehäuse mit mindestens einer Ab¬ lauföffnung in seinem Boden zur Aufnahme von feuchtigkeitsempfindlichen Gegenständen. OBJECTS The invention relates to a housing with at least one from ¬ overflow opening in its bottom for receiving the moisture-sensitive objects.
Ein derartiges Gehäuse wird beispielsweise in der Logistik als Container verwendet. Ein solcher Container ist allseitig verschlossen, jedoch nicht luftdicht, so dass Feuchtigkeit in das Innere des Containers gelangen und kondensieren kann. Das Kondenswasser kann zu Schäden an feuchtigkeitsempfindlichen Gegenständen im Innern des Containers führen, sofern diese Gegenstände nicht jeweils durch eine entsprechende Verpackung vor Feuchtigkeit geschützt sind. Das Kondenswasser wird in der Regel durch eine Öffnung im Boden des Containers abgelei¬ tet . Auch zum Beispiel Schaltschränke weisen ein äußeres Gehäuse auf, das häufig nicht luftdicht abgeschlossen ist. Stehen diese Schaltschränke in einer feuchten Atmosphäre, dann kann es zu gefährlichen Auswirkungen eingedrungener Feuchtigkeit auf in den Schaltschränken untergebrachte elektrische oder elektronische Bauelemente kommen. Such a housing is used for example in logistics as a container. Such a container is closed on all sides, but not airtight, so that moisture can reach the interior of the container and condense. Condensation may cause damage to moisture-sensitive objects inside the container, provided that such items are not protected from moisture by appropriate packaging. The condensation is usually abgelei ¬ tet through an opening in the bottom of the container. Also, for example, cabinets have an outer housing, which is often not sealed airtight. If these control cabinets are in a humid atmosphere, dangerous effects of moisture ingress can occur on electrical or electronic components housed in the control cabinets.
Der Erfindung liegt die Aufgabe zugrunde, em Gehäuse an¬ zugeben, das sich in seinem Innern auch bei äußerer Feuchtig- keit trocken halten lässt. The invention has the object of specifying em housing at ¬, which can be kept dry during ness external moisture in its interior.
Zur Lösung dieser Aufgabe ist bei einem Gehäuse zur Aufnahme von feuchtigkeitsempfindlichen Gegenständen erfindungsgemäß am Gehäuse mindestens ein Peltier-Element mit seiner kalten Seite innen liegend und mit seiner warmen Seite nach außen weisend angeordnet. To solve this problem, according to the invention, at least one Peltier element with its cold side lying inside and with its warm side pointing outwards are arranged in a housing for receiving moisture-sensitive objects.
Es ist zwar bekannt (http : //de . wikipedia .org/wiki/Peltier- Element) , in einem Gehäuse ein Peltier-Element unterzubrin gen, jedoch handelt es sich bei dem bekannten Gehäuse um ein CPU-Gehäuse, indem das Peltier-Element Bestandteil eines CPU- Kühlers ist, um die Temperatur unterhalb der Gehäuseinnentem- peratur abzukühlen. Although it is known (http://de.wikipedia.org/wiki/Peltier-element), in a housing a Peltier element unterzubrin However, the known housing is a CPU housing in that the Peltier element is part of a CPU cooler in order to cool the temperature below the housing internal temperature.
Ein wesentlicher Vorteil des erfindungsgemäßen Gehäuses be- steht darin, das mit dem Peltier-Element eine gezielte Kon- densation der in seinem Innenräum vorhandenen Feuchtigkeit vorgenommen wird und dadurch in dem Gehäuse befindliche Ge- genstände vor Feuchtigkeitseinwirkungen gut geschützt sind. An essential advantage of the housing according to the invention consists in the fact that with the Peltier element a specific condensation of the moisture present in its interior space is carried out and thus objects located in the housing are well protected against the effects of moisture.
Bei dem erfindungsgemäßen Gehäuse kann das Peltier-Element in unterschiedlichen Bereichen angebracht sein; so kann es im Bereich der Decke des Gehäuses angebracht sein, weil sich dort die warme und viel Feuchtigkeit enthaltende Luft sam¬ melt. Als besonders vorteilhaft wird es jedoch angesehen, das Peltier-Element am Boden des Gehäuses im Bereich der Ablauf¬ öffnung angebracht ist, weil sich dort das Kondenswasser gut sammeln und abführen lässt. In the housing according to the invention, the Peltier element may be mounted in different areas; so it can be mounted in the area of the ceiling of the housing, because there the warm and much moisture-containing air sam ¬ melt. Especially advantageous is, however, considered, the Peltier element is attached to the bottom of the housing in the area of the discharge opening ¬ because there can collect the condensed water well and dissipate.
Vorteilhaft erscheint es zur guten Ableitung des Kondenswas¬ sers ferner, wenn das Peltier-Element eine Abflussöffnung aufweist und zu dieser hin vertieft ist. Advantageously, it seems also to good discharge of condensation water ¬ sers when the Peltier element has a discharge opening and is recessed towards the latter.
Bei einer weiteren vorteilhaften Ausführungsform des erfindungsgemäßen Gehäuses ist das Peltier-Element in der Ablauf¬ öffnung gehalten; diese wird somit zur Halterung des Peltier- Elements mit ausgenutzt. In a further advantageous embodiment of the housing according to the invention, the Peltier element is held in the drain ¬ opening; This is thus used to hold the Peltier element with.
Andererseits erscheint es auch vorteilhaft, wenn das Peltier- Element mit seiner warmen Seite auf einem metallenen Wasserablauf- und Druckausgleich-Stopfen in der AblaufÖffnung des Gehäuses aufgebracht ist. Das Peltier-Element kann bei dieser Ausführungsvariante eine mit dem Wasserablauf- und Druckaus¬ gleich-Stopfen zusammen hängende Baueinheit bilden, die vorgefertigt und einfach an dem Gehäuse angebracht werden kann. Dabei kann es auch vorteilhaft sein, wenn die Abflussöffnung des Peltier-Elementes in einen Abflusskanal des Wasserablauf- und Druckausgleich-Stopfens mündet. In vorteilhafterweise führen zu dem Abflusskanal des Wasser¬ ablauf- und Druckausgleich-Stopfens Entwässerungskanäle des Gehäuses . On the other hand, it also appears advantageous if the Peltier element is applied with its warm side on a metal water drainage and pressure equalization plug in the drain opening of the housing. The Peltier element can in this embodiment form a together with the Wasserablauf- and Druckaus ¬ same stopper-hanging unit that can be prefabricated and easily attached to the housing. It may also be advantageous if the outflow opening of the Peltier element opens into a drainage channel of the water drain and pressure equalization plug. In an advantageous manner lead to the drainage channel of the water ¬ drain and pressure equalization plug drainage channels of the housing.
Um den Ablauf des Kondenswassers von dem Peltier-Element op- timal zu gestalten, ist dessen Oberfläche speziell behandelt. In diesem Zusammenhang wird es als besonders vorteilhaft an¬ gesehen, wenn das Peltier-Element eine ionenimplantierte Oberfläche aufweist. Es kann aber auch günstig sein, das Pel¬ tier-Element mit einer den Lotus-Effekt aufweisenden Oberflä- che zu versehen. In order to optimize the drainage of the condensed water from the Peltier element, its surface is specially treated. In this connection it is seen as particularly advantageous in ¬ when the Peltier element comprises an ion-implanted surface. But it may also be beneficial to provide the pel ¬ animal element with a lotus effect having surface.
Zur weiteren Erläuterung der Erfindung ist in der Figur ein Schnitt durch ein Ausführungsbeispiel des erfindungsgemäßen Gehäuses dargestellt. To further explain the invention, a section through an embodiment of the housing according to the invention is shown in the figure.
In der Figur ist ein Gehäuse 1 mit zwei Seitenwänden 2 und 3, einer Rückwand 4, einer Deckenwand 5 und einem Boden 6 zu er¬ kennen; eine Vorderwand ist nicht gezeigt. Im Boden 6 des Ge¬ häuses 1 befindet sich eine AblaufÖffnung 7, in der ein me- tallener Wasserablauf- und Druckausgleich-Stopfen 8 angebracht ist. Der Wasserablauf- und Druckausgleich-Stopfen 8 ist mit einem Abflusskanal 9 versehen. Außerdem weist der Wasserablauf- und Druckausgleich-Stopfen 8 seitliche Entwäs¬ serungskanäle 10 auf. Der Wasserablauf- und Druckausgleich- Stopfen 8 ist auf seiner oberen, im Gehäuse 1 liegenden Oberfläche 11 konkav ausgebildet. In the figure, a housing 1 with two side walls 2 and 3, a rear wall 4, a ceiling wall 5 and a bottom 6 to know it ¬ ; a front wall is not shown. In the bottom 6 of the Ge ¬ housing 1 is a drain opening 7, in which a me- ternal water drainage and pressure equalization plug 8 is attached. The water drainage and pressure equalization plug 8 is provided with a drainage channel 9. In addition, the water drainage and pressure equalization plug 8 lateral Entwäs ¬ serungskanäle 10 on. The water drainage and pressure equalization plug 8 is concave on its upper surface 11 located in the housing 1.
Von der Oberfläche 11 des Wasserablauf- und Druckausgleich- Stopfens 8 getragen ist ein entsprechend geformtes Peltier- Element 12, das sich somit zu einer Abflussöffnung 13 im Peltier-Element 12 hin vertieft; somit sammelt sich bei einer durch das Peltier-Element 12 geförderten Bildung von Kondenswasser dieses Wasser vor der Abflussöffnung 13 und wird über diese und den damit fluchtend angeordneten Abflusskanal 9 aus dem Innern des Gehäuses 1 hinaus abgeführt. Dabei ist das Peltier-Element 12 so angeordnet, dass seine kalte Seite 14 dem Innern des Gehäuses 1 zugewandt liegt, während seine war¬ me Seite 15 engen thermischen Kontakt mit dem metallenen Wasserablauf- und Druckausgleich-Stopfen 8 hat. Supported by the surface 11 of the water drainage and pressure equalization plug 8 is a correspondingly shaped Peltier element 12, which thus deepens toward a discharge opening 13 in the Peltier element 12; thus collects in a funded by the Peltier element 12 formation of condensation water this water in front of the drain opening 13 and is about this and the outflow channel 9 arranged in alignment therewith are removed from the interior of the housing 1. In this case, the Peltier element 12 is arranged so that its cold side 14 faces the interior of the housing 1, while his war ¬ me page 15 has close thermal contact with the metal water drain and pressure equalization plug 8.
Abschließend ist noch anzumerken, dass eine zum Betreiben des Peltier-Elementes 12 notwendige Stromquelle der besseren Übersichtlichkeit halber in der Figur nicht dargestellt ist. Ferner ist noch darauf hinzuweisen, dass selbstverständlich bei Bedarf außer dem einen Peltier-Element 12 weitere derartige Elemente am Gehäuse 1 befestigt sein können. Finally, it should be noted that for the sake of clarity, a current source necessary for operating the Peltier element 12 is not shown in the figure. It should also be pointed out that, of course, if necessary, in addition to the one Peltier element 12, further such elements can be fastened to the housing 1.
