Description
Die Erfindung bezieht sich auf einen Wärmeaustauscher für Gase für mit einem indifferenten Gag arbeitende Abs.orptionskälteapparate, mit zwei koaxial verlaufenden Rohren, in denen die Gase mehrfachumlenkende Organe vorgesehen sind.The invention relates to a heat exchanger for gases for Abs.orptionskühlteapparate working with an indifferent gag, with two coaxial extending pipes in which the gases multiple deflecting organs are provided.
Bei bekannten Wärmeaustauschern dieser Art sind die Umlenkorgane als von den Rohren abstehende, in die Gaswege ragende Teile ausgebildet, die somit in erster Linie zur Durchwirbelung der Gase dienen und nur in beschränktem Maße imstande sind, Wärme abzuleiten, weil sie rippenartig auf den sonst glatten Rohrwandungen angebracht sind, durch welche einzig der Wärmedurchgang erfolgen kann.In known heat exchangers of this type, the deflection elements are as from the pipes protruding, protruding into the gas path parts are formed, which are thus in serve primarily to swirl the gases and are only able to a limited extent are to dissipate heat because they are rib-like on the otherwise smooth pipe walls are attached, through which only the heat transfer can take place.
Andererseits ist eine Ausführung bekannt, bei der die Wand des inneren Rohres längs verlaufende, außen scharfkantige Ausbuchtungen aufweist, die bis an die Innenseite des äußeren Rohres ragen und eine Vergrößerung der wärmeübertragenden Fläche ergeben. In das Innere des Innenrohres ragen noch längs verlaufende, von den Ausbuchtungen ausgehende Rippen, doch sind keinerlei Umlenkorgane für die Gase vorhanden, um eine Durchwirbelung zu erzeugen.On the other hand, a design is known in which the wall of the inner Tube has longitudinal, sharp-edged bulges on the outside, which up to protrude the inside of the outer tube and enlarge the heat transferring Area. In the interior of the inner tube, protruding from ribs emanating from the bulges, but are in no way diverting organs for the gases present to create a vortex.
Demgegenüber sind gemäß der vorliegenden Erfindung die Umlenkorgane derart angeordnet und ausgebildet, daß sowohl eine Durchwirbelung beider Gase als auch eine Vergrößerung der Fläche erzielt wird, durch welche der Wärmedurchgang erfolgt. Diese vorteilhafte Ausbildung des Wärmeaustauschers wird erfindungsgemäß dadurch erreicht, d'aß die beiden Rohre miteinander durch zwei längs verlaufende Rippen verbunden sind, die in einer Diametralebene liegen und in Abständen voneinander abwechselnd auf der einen und anderen Seite der Rippen angeordnete Halbringe tragen, wobei das innere Rohr von Querrohren durchsetzt ist, deren Achsen in einer Diametralebene liegen, die senkrecht zu der die Rippen enthaltenden Diametralebene verläuft.In contrast, according to the present invention, the deflecting members arranged and designed such that both a turbulence of both gases as an increase in the area through which the heat transfer is achieved is also achieved he follows. This advantageous design of the heat exchanger is according to the invention thereby achieved, d'ass the two tubes together by two longitudinal ones Ribs are connected, which lie in a diametrical plane and at a distance from each other wear half rings alternately on one side and the other of the ribs, the inner tube being penetrated by transverse tubes, the axes of which are in a diametrical plane lie perpendicular to the diametrical plane containing the ribs.
Auf diese Weise wird das im von beiden Rohren gebildeten Ringraum befindliche Gas abwechselnd durch die Querrohre hindurch von der einen auf die andere Seite der von den beiden Rippen bestimmten Diametralebene geleitet, und das im inneren Rohr strömende Gas muß an den dieses innere Rohr durchsetzenden Querrohren vorbeistreichen. Diese Querrohre bewirken somit eine Durchwirbelung der Gase und stellen eine zusätzliche Fläche für den direkten Wärmedurchgang dar.In this way, it is in the annulus formed by the two tubes The gas located alternately through the cross tubes from one to the other Side of the diametrical plane defined by the two ribs, and that inside Gas flowing through the pipe must sweep past the transverse pipes penetrating this inner pipe. These cross pipes thus cause a turbulence of the gases and provide an additional Area for direct heat transfer.
In der Zeichnung ist ein Ausführungsbeispiel eines Wärmeabtauschers gemäß der Erfindung dargestellt, und zwar zeigt Fig. i eine Seitenansicht des Wärmeabtauschers, zum Teil im Schnitt, Fig. 2 eine Draufsicht desselben, wiederum zum Teil im Schnitt, und Fig. 3 einen Querschnitt des Wärmeabtauschers. Der gezeichnete Wärmeabtauscher weist zwei konzentrisch zueinander verlaufende Rohre i und 2 auf. Der ringförmige Zwischenraum zwischen den Rohren ist durch zwei, in einer Diametralebene liegende Rippen 3 in zwei Hälften aufgeteilt.In the drawing is an embodiment of a heat exchanger shown according to the invention, namely Fig. i shows a side view of the heat exchanger, partly in section, FIG. 2 is a plan view of the same, again partly in section, and Fig. 3 is a cross section of the heat exchanger. The drawn heat exchanger has two tubes i and 2 which run concentrically to one another. The ring-shaped one The space between the tubes is by two, lying in a diametrical plane Ribs 3 split in half.
In Abständen voneinander sind abwechselnd auf gegenüberliegenden Seiten Halbringe 4 auf dem Innenrohr 2 angebracht, welche bis zum Außenrohr reichen.At intervals are alternating on opposite sides Half rings 4 attached to the inner tube 2, which extend to the outer tube.
In einer Diametralebene, senkrecht zur Diametralebene welche die Rippen 3 enthält, sind Rohre 5 in Bohrungen des Innenrohres 2 befestigt, z. B. durch Ausweiten der Rohrenden.In a diametrical plane, perpendicular to the diametrical plane which the ribs 3 contains, tubes 5 are fixed in bores of the inner tube 2, for. B. by expanding the pipe ends.
Die kalten, vom Verdampfer abgehenden Gase umspülen die Rohre 5, und diese werden dabei sehr stark abgekühlt, die warmen, vom Absorber kommenden Gase hingegen werden durch die Rippen behindert und müssen immer abwechslungsweise durch die stark gekühlten Rohre von einer Kammer in die andere strömen, um zum Ausgang und dann in den Verdampfer zu gelangen.The cold gases emanating from the evaporator wash around the tubes 5, and these are cooled down very strongly, the warm gases coming from the absorber however, are hindered by the ribs and always have to go through alternately the highly cooled tubes flow from one chamber to the other to get to the exit and then get into the vaporizer.
Die Rohre 5 werden zu Gruppen zusamm.engefaßt, wobei die Größe der 'einzelnen Rohre immer so gehalten wird, daß keine Verstopfungen durch Flüssigkeitstropfen verursacht werden können.The tubes 5 are summarized in groups, the size of the 'The individual pipes are always held in such a way that no blockages caused by drops of liquid can be caused.
