Description
Verdampfer für Absorptionakälteapparate. Vorliegende Erfindung bezieht sich auf einen Verdampfer für Absorptionskälteappa- rate, der zwei koaxial zueinander, horizontal liegende Rohre aufweist, die zwischen sich den Verdampferraum einschliessen.
Bei derartigen Verdampfern ist es wichtig, dass das zu verdampfende Kältemittel eine .iiögliehst grosse Oberfläche benetzt.
Zur Erreichung dieses Zweckes ist gemäss der Erfindung die die eine Verdampferwand bildende Aussenwand des Innenrohres mit sich kreuzenden Rillen versehen.
In der beiliegenden Zeichnung ist ein Aus- führuingsbeispiel eines Verdampfers gemäss der Erfindung dargestellt, und zwar zeigt: Fig.l einen Längsschnitt durch den Ver dampfer, Fig-.2 einen Querschnitt eines Teils des Verdampferinnenrohres in grösserem Mass stab und Fig. 3 eine Draufsicht zu Fig. 2.
Der -ezeichnete Verdampfer weist zwei koaxial zueinander, horizontal liegende Rohre 1 und 2 auf, die beiderends miteinander ver bundensind und den Verdampferraum 3 ein- s@-hliessen. Diesem Verdampferraum 3 wird das zu verdampfende Kältemittel durch ein Rohr 4 zugeführt. Durch ein Rohr 5 fliesst ein inertes Gas, zum Beispiel Wasserstoff, dem Verdampfer zu.
Das verdampfte Kälte mittel tritt, gemischt mit dem inerten Gas, durch ein Rohr ö aus dem Verdampfer aus.
Das flüssige, zu verdampfende Kältemittel tropft aus dem Rohr 4 auf die Wand des Innenrohres 2. Um nun eine gute Verteilung des Kältemittels auf dem Rohr 2 zu erwirken und damit eine grosse Oberfläche des letzteren zu benetzen, ist die Aussenwand des Innen rohres 2 mit sich kreuzenden Rillen 7 ver sehen (Fig.2 und 3), in denen das zu ver dampfende Kältemittel durch Kapillarwir- king fliesst.
Die Rillen 7 können vorteilhafterweise als Riffeln der genannten Rohrwandung ausge bildet sein.
Evaporator for absorption refrigerators. The present invention relates to an evaporator for absorption refrigeration apparatus, which has two horizontally lying tubes which are coaxial to one another and which enclose the evaporator space between them.
In evaporators of this type, it is important that the refrigerant to be evaporated wets the largest possible surface.
To achieve this purpose, according to the invention, the outer wall of the inner tube which forms an evaporator wall is provided with intersecting grooves.
In the accompanying drawing, an exemplary embodiment of an evaporator according to the invention is shown, namely: Fig.l shows a longitudinal section through the evaporator, Fig. 2 a cross section of part of the evaporator inner tube on a larger scale and Fig. 3 a plan view to Fig. 2.
The vaporizer shown has two tubes 1 and 2 lying horizontally coaxially to one another, which are connected to one another at both ends and which enclose the vaporizer space 3. The refrigerant to be evaporated is fed to this evaporator chamber 3 through a pipe 4. An inert gas, for example hydrogen, flows through a pipe 5 to the evaporator.
The evaporated refrigerant, mixed with the inert gas, emerges from the evaporator through a pipe ö.
The liquid refrigerant to be evaporated drips from the tube 4 onto the wall of the inner tube 2. In order to now achieve a good distribution of the refrigerant on the tube 2 and thus wet a large surface of the latter, the outer wall of the inner tube 2 is with it See intersecting grooves 7 (Fig. 2 and 3), in which the refrigerant to be evaporated flows by capillary action.
The grooves 7 can advantageously be formed out as corrugations of said pipe wall.
