Description

Transportable Kühlvorrichtung Die Erfindung betrifft eine transportable, zum Eintauchen in flüssige Speisen o, d:gl. bestimmte Kühlvorrichtung. Der Tauchkühler ist als Kompressionskältemaschine mit Luftkühlung ausgebildet. Der Verdampfer wird in die Speisen eingetaucht.Transportable cooling device The invention relates to a transportable, for immersion in liquid food o, d: gl. certain cooler. The immersion cooler is designed as a compression chiller with air cooling. The vaporizer will immersed in the food.

Bei solchen Tauchkühlern kommt es darauf an, die Außenabmessungen und das Gewicht aller Teile möglichst gering zu halten. Um nun bei den erforderlichen geringen Abmessungen des Verdampfers eine ausreichende Verdampfung zu erzielen, ist nach der Erfindung der Mantel des in die Speisen einzutauchenden Verdan2pfers innen mit einer Schicht aus porösem, das flüssige Kältemittel fein verteilendem Füllstoff versehen, während sich in seinem freien Innenraum das Absaugrohr für das verdampfte Kältemittel befindet. Die Schicht des Füllstoffes kann innen durch ein Drahtnetz gehalten werden.With such immersion coolers, it depends on the external dimensions and to keep the weight of all parts as low as possible. To now with the necessary small dimensions of the evaporator to achieve sufficient evaporation, is, according to the invention, the jacket of the evaporator to be immersed in the food inside with a layer of porous, the liquid refrigerant finely distributing Filler provided, while the suction tube for the evaporated refrigerant is located. The layer of filler can be inside through a Wire mesh are kept.

In der Zeichnung bedeutet g einen an einer Membran f befestigten, als Kolben wirkenden Schwingkörper. Dieser Schwingkörper wird durch Elektromagnete a hin und her bewegt. Das aus dem Verdampfer durch ein Saugrohr d abgesaugte Kältemittel wird durch ein Druckventil e hindurch in die luftgekühlte Kühlschlange b gedrückt, in welcher das Kältemittel kondensiert. Das flüssige Kältemittel gelangt durch ein regelbares Drosselventil c in ein Rohr. und tritt bei h in die Füllmasse ein. Die Füllmasse i ist in einer Schicht an der Innenfläche des Verdampfers verteilt. Die Schicht kann durch ein Drahtnetz o. dgl. an der Innenfläche des Verdampfers gehalten werden. Als Füllstoff können beispielsweise Watte, Glaswolle, Holzmehl, poröser Ton verwendet werden. Das vom Drosselventil zum Verdampfer führende Rohr könnte auch innerhalb der Füllmasse :entlang geführt werden. Im inneren freien Raum h des Verdampfers sammelt sich das verdampfte Kältemittel und gelangt von dort durch das Saugrohr d wieder zum Kompressor. Durch die an der Innenfläche des Verdampfermantels verteilte Füllmasse wird die verdampfende Oberfläche vergrößert, so daß trotz geringer Abmessungen und geringen Gewichts des Verdampfers eine ausreichende Verdampfung erzielt wird.In the drawing, g means one attached to a membrane f, oscillating body acting as a piston. This vibrating body is made by electromagnets a moved back and forth. The refrigerant sucked out of the evaporator through a suction pipe d is pressed through a pressure valve e into the air-cooled cooling coil b, in which the refrigerant condenses. The liquid refrigerant passes through a adjustable throttle valve c in a pipe. and enters the filling compound at h. the Filling compound i is distributed in a layer on the inner surface of the evaporator. the Layer can be held on the inner surface of the evaporator by a wire mesh or the like will. As a filler, for example, cotton wool, glass wool, wood flour, porous Sound can be used. The pipe leading from the throttle valve to the evaporator could also within the filling compound: be guided along. In the inner free space h des Evaporator collects the evaporated refrigerant and passes from there through the Suction pipe d back to the compressor. Due to the on the inner surface of the evaporator jacket distributed filling compound, the evaporating surface is enlarged, so that despite less Dimensions and low weight of the evaporator ensure sufficient evaporation is achieved.

Es ist bereits bekannt, bei stationären Absorptonskältemaschinen im Innern des Verdampfers mehrere Zellen anzuordnen, die mit einer porösen Füllmasse angefüllt sind, um das Kältemittel fein zu verteilen. Die Erfindung beruht auf der Erkenntnis, daß es bei Verwendung dieses bekannten Mittels möglich ist, einen besonders leichten Tauchkühler von geringen Abmessungen herzustellen, wenn die poröse Füllmasse in einer Schicht an der Innenfläche des Verdampfermantels verteilt wird.It is already known in the stationary absorption chillers Arrange several cells inside the evaporator, which are filled with a porous material are filled to distribute the refrigerant finely. The invention is based on Realization that it is possible to use this known agent, one in particular to manufacture lightweight immersion coolers of small dimensions, if the porous filling compound is distributed in a layer on the inner surface of the evaporator jacket.
