Thermoelektrisch "betriebener KleinkühlbehälterThermoelectrically "operated small cooling container
Die Neuerung betrifft einen thermoelektrisch betriebenen Kleinkühlb e hält er.The innovation concerns a thermoelectrically operated small refrigerator e he holds.
Es besteht die Aufgabe, einen kompakten Kleinkühlbehälter zu erstellen, dessen Außenabmessung klein im Verhältnis zum inneren Nutzraum ist.The task is to create a compact small cooling container, whose outer dimension is small in relation to the inner usable space.
Auf wartungsfreies und geräuschloses Arbeiten des Kühlgerätes wird besonderen Wert gelegt. Ferner muß es einen möglichst guten Wirkungsgrad aufweisen, da das Gerät vorzugsweise an Batterien betrieben werden soll.Special emphasis is placed on maintenance-free and noiseless operation of the cooling device. It must also be as good as possible Have efficiency, since the device should preferably be operated on batteries.
Eine Lösung der Aufgabe stellt das in der Figur gezeigte und im folgenden beschriebene Ausführungsbeispiel eines Kleinkühlbehälters gemäß der !Teuerung dar.A solution to the problem is shown in the figure and in the following described embodiment of a small cooling container according to the!
Der eigentliche Kühlgutbehälter ist als doppelwandiges Gefäß aufgebaut, bestehend aus dem thermisch gut leitenden Innengefäß 2 und einem das Innengefäß mit Abstand umgebenden Außengefäß 9 vorzugsweise mit gut reflektierender Außenfläche. (Der Deckel des Gefäßes in üblicher Ausführung ist in der Figur nicht dargestellt.)The actual refrigerated goods container is constructed as a double-walled vessel, consisting of the thermally highly conductive inner vessel 2 and an outer vessel 9 surrounding the inner vessel at a distance, preferably with a well reflective outer surface. (The usual design of the lid of the vessel is not shown in the figure.)
Die oberen Sander beider Gefäße 2 und 9 sind mit einer Kappe 3 aus schlecht wärmeleitendem Material gasdicht verbunden. Der so entstandene Zwischenraum 10 dient zur Aufnahme eines als Isolationsmittel dienenden thermisch schlecht leitenden Gases z.B. Frigen, Xenon, Schwefeldioxyd.The upper sanders of both vessels 2 and 9 have a cap 3 made of poorly thermally conductive material connected in a gastight manner. The resulting space 10 is used to accommodate an insulating means thermally poorly conducting gas, e.g. Frigen, xenon, sulfur dioxide.
Die Strahlung und die Konvektion wird durch spiegelnde Flächen und enge Zwischenräume herabgesetzt, z.B. durch parallelliegende hochglänzende Aluminiumfolien 8, die mit Querwänden 11 als Abstandshalter distanziert werden. Die Isolation kann auch durch Vakuum im Zwischenraum 10 erfolgen.The radiation and the convection are reduced by reflective surfaces and narrow spaces, e.g. by parallel ones high-gloss aluminum foils 8 with transverse walls 11 as spacers be distanced. The insulation can also take place by means of a vacuum in the space 10.
Bei einer bevorzugten Ausführungsform der Kappe 3 ist vorgesehen, daß sie aus Kunststoff besteht und angespritzte Rippen 13 aufweist, welche eine Verkleidung des Luftaustrittes des Wärmeaustauschers 4 bilden und diesen an seinem oberen Ende ringartig umgreifen. In a preferred embodiment of the cap 3 it is provided that it consists of plastic and has molded-on ribs 13, which form a cladding of the air outlet of the heat exchanger 4 and surround it like a ring at its upper end.
Diese Verkleidung muß so gestaltet sein, daß die natürliche Luftkonvektion möglichst wenig behindert wird. Gegebenenfalls kann auch der Lufteintritt unten am Wärmeaustauscher verkleidet werden.This cladding must be designed so that the natural air convection is hindered as little as possible. If necessary, the air inlet at the bottom of the heat exchanger can also be covered.
Die Befestigung des aus Peltierelementen bestehenden Kühlbloeks mit möglichst geringem thermischen Widerstand zwischen Kühlblock und dem Kühlgutbehälter 2 einerseits, bzw. einem Wärmeaustauscher andererseits, kann durch Verkleben mittels eines dünnflüssigen Klebers (z.B. Epoxydharz) erfolgen.The attachment of the cooling block consisting of Peltier elements with the lowest possible thermal resistance between the cooling block and the refrigerated goods container 2 on the one hand, or a heat exchanger on the other hand, it can be done by gluing with a thin adhesive (e.g. epoxy resin).
-2--2-
Die elektrische Isolation der einzelnen Peltierelemente untereinander erfolgt dabei durch Oxydation des Metalls (z.B. eloxiertes Aluminium) oder durch eine zwischengelegte Folie.The electrical isolation of the individual Peltier elements from one another takes place through oxidation of the metal (e.g. anodized aluminum) or through an interposed foil.
Während die Kälteleistung, erzeugt vom Kühlblock 1, direkt auf das metallische, thermisch gut leitende Innengefäß 2 übertragen wird, erfolgt die Wärmeabfuhr über einen außerhalb des Außengefäßes 9 angeordneten Wärmeaustauscher 4 durch natürliche Luft-, konvektion und durch Strahlung.While the cooling power generated by the cooling block 1 is transferred directly to the metallic, thermally highly conductive inner vessel 2 the heat is dissipated via a heat exchanger 4 arranged outside the outer vessel 9 by natural air, convection and radiation.
Der Wärmeaustauscher 4 setzt sich aus einer Anzahl mit Längsrippen 15 versehenen Rohre. 6 zusammen, welche das Außengefäß 9 kranzförmig umgeben, wobei die Rippen etwa radial zur Gefäßmittelachse ausgerichtet sind.The heat exchanger 4 is composed of a number with longitudinal ribs 15 provided tubes. 6, which surround the outer vessel 9 in a ring shape, the ribs being approximately radial to the central axis of the vessel are aligned.
Die gerippten Rohre 6 können dabei einzeln angeordnet sein oder auch z.B. durch Löten oder Kleben der außen liegenden Rippenkanten miteinander verbunden werden, wodurch die mechanische Festigkeit des Wärmetauschers erhöht wird. Unabhängig von der Profilgebung der längsgerippten Rohre 6 entsteht in den senkrecht oder nur wenig geneigt verlaufenden Hohlräumen 14, die von den Rippen 15, Rohren 6 und der Wandung des Außengefäßes 9 gebildet werden, eine Kaminwirkung mit verstärkter Luftkonvektion.The ribbed tubes 6 can be arranged individually or, for example, by soldering or gluing the outer rib edges are connected to each other, whereby the mechanical strength of the heat exchanger is increased. Regardless of the profile of the longitudinally ribbed tubes 6 is created in the vertically or only slightly inclined cavities 14, which are formed by the ribs 15, Tubes 6 and the wall of the outer vessel 9 are formed, a chimney effect with increased air convection.
Die an der Warmseite des Kühlblockes 1 entstehende konzentrierte Wärmeleistung wird an ein mit radial und schräg nach oben verlaufenden Verbindungsrohren 7 besetztes, thermisch gut leitendes Bodenstück 12 gegeben. Die Rohre 7 stehen mit den längsgerippten Rohren 6 in Verbindung oder sind Teile derselben. In den Rohren befindet sich ein Kältemittel z.B. Frigen, welches durch die über das Bodenstück 12 zugeführte Wärme verdampft, als Gas in den Rohren 6, 7, aufsteigt, seine Wärme in den gekühlten Rohren 7 abgibt, kondensiert und an den Innenflächen der Rohre 7, 6 zurückläuft. Das Kältemittel kann sich dabei getrennt in den einzelnen beidseitig verschlossenen Rohren 7, 6 befinden, was den Vorteil hat, daß ein schadhaftes Rohr die Funktion des Gerätes kaum beeinflußt.The concentrated heat generated on the warm side of the cooling block 1 is transferred to a radially and diagonally upwardly directed Connecting pipes 7 occupied, thermally highly conductive bottom piece 12 given. The tubes 7 stand with the longitudinally ribbed Pipes 6 in connection or are parts of the same. There is a refrigerant in the pipes, e.g. Frigen, which flows through the over the heat supplied to the bottom piece 12 evaporates as a gas in the tubes 6, 7, rises, gives off its heat in the cooled tubes 7, condenses and runs back on the inner surfaces of the tubes 7, 6. The refrigerant can be located separately in the individual tubes 7, 6, which are closed on both sides, which has the advantage of that a damaged pipe hardly affects the function of the device.
Bei einer anderen Ausführungsform ist vorgesehen, daß die unteren Enden der Verbindungsrohre 7 offen sind und in einem abgeschlossenen Raum im Bodenstück 12 münden.In another embodiment it is provided that the lower Ends of the connecting pipes 7 are open and open into a closed space in the base piece 12.
Somit besitzt das gesamte Gerät keine Verschleißteile und gewährleistet damit einen absolut wartungsfreien und zuverlässigen Betrieb. Thus, the entire device has no wearing parts and is guaranteed thus an absolutely maintenance-free and reliable operation.
