Die Aufgabe der vorliegenden Erfindung besteht in der Verbesserung des Wärmeaustauschers nach der vorstehend erwähnten Art.The object of the present invention is to improve of Heat exchanger according to the type mentioned above.
Die Lösung der Aufgabe besteht darin, daß ein solcher Wärmeist austauscher gekennzeichnet/durch eine Reihe von einen Abstand voneinander aufweisenden hohlen Gliedern, die Kanäle für das erste Fluid bilden, wobei die Zwischenräume zwischen benachbarten hohlen Gliedern eine Folge von Kühlrippen enthalten, die sich im wesentlichen quer zu den hohlen Gliedern erstrecken und durch Bereiche von Aluminiumstreifen gebildet sind, wobei wenigstens einer der Streifen mittels eines Klebemittels unlösbar mit wenigstens einem der hohlen Glieder in Zonen des Streifens verbunden ist, die die Dreiecksbasen bilden, und wobei die Zonen sich im wesentlichen parallel zu der ihnen naheliegenden Oberfläche des hohlen Gliedes erstrecken, mit welcher sie mittels des Klebemittels unlösbar verbunden sind.The solution to the problem is that such a heat exchanger characterized / by a series of spaced apart hollow Limbs that form channels for the first fluid, with the spaces between adjacent hollow members contain a series of cooling fins, which are essentially extend across the hollow links and through areas of aluminum strips are formed, wherein at least one of the strips by means of an adhesive is undetachable is connected to at least one of the hollow members in zones of the strip which which form the triangular bases, and wherein the zones are substantially parallel to the surface of the hollow member that is close to them, with which they mean of the adhesive are inextricably linked.
Die Erfindung ist nachstehend anhand eines in der anliegenden Zeichnung dargesüllten Ausführungsbeispieles näher erläuert.The invention is described below with reference to one in the accompanying drawing illustrated embodiment explained in more detail.
Es zeigen: Figur 1 eine Seitenansicht einer Ausführungsform eines Kühlkondensators, Figur 2 einen Schnitt nach der Linie 2 - 2 der Figur 1, Figur 3 eine teilweise dargestellte Seitenansicht einer alternativen Ausführungsform zu Figur 1.They show: FIG. 1 a side view of an embodiment of a Cooling condenser, Figure 2 is a section along the line 2-2 of Figure 1, Figure 3 is a partially illustrated side view of an alternative embodiment to FIG Figure 1.
Nach der Zeichnung wird ein zu kühlendes Fluid, das eine Flüssigkeit, Flüssigkeitsdampf oder ein Gas sein kann, durch ein wellenförmig extrudiertes Aluminiumrohr 10 geleitet, welches so ausgebildet ist, daß parallele hohle Glieder 11 über bogenförmige Endteile 12 miteinander in Verbindung stehen. Das Rohr 1o weist mehrere innere, querverlaufende Versteifungsrippen i3 auf und besitzt eine typische Wanddicke von 0,50 mm bis 0,76 mm, wobei jedoch auch jede geeignete Wanddicke verwendet werden kann, die dem Druck innerhalb des Rohres 10 angemessen ist.According to the drawing, a fluid to be cooled, which is a liquid, Can be liquid vapor or a gas, through a wave-shaped extruded aluminum tube 10 headed, which so is designed that parallel hollow members 11 are connected to one another via arcuate end parts 12. The tube 1o has several inner, transverse stiffening ribs i3 and has a typical Wall thickness from 0.50 mm to 0.76 mm, although any suitable wall thickness is also used which is appropriate for the pressure within the tube 10.
Das Rohr 10 wird durch einen zwischen einander benachbarten hohlen Gliedern 11 hindurchgeführten Luftstrom gekühlt, und zwar in einer Richtung, wie sie im wesentlichen durch die Pfeile in Figur 2 angegeben ist. Die Wärmeübertragung vom Rohr 10 auf die Kühlluft wird durch sekundäre Wärmeübertragungsflächen in Form von Leitflächen bzw. Rippen 14 unterstützt, die durch Bereiche von rippenbildend gefalteter Aluminiumfolie gebildet sind, wobei die Folie typischerweise eine Dicke von 0,10 mm aufweist. Jeder Streifen aus Aluminiumfolie ist mittels eines Klebemittels mit den Oberflächen des ihm naheliegenden hohlen Gliedes 11 unlösbar verbunden.The tube 10 is hollowed by an adjacent one therebetween Limbs 11 passed through air flow cooled, in one direction, such as it is essentially indicated by the arrows in FIG. The heat transfer from the pipe 10 to the cooling air is shaped by secondary heat transfer surfaces supported by guide surfaces or ribs 14, which are formed by areas of ribs folded aluminum foil, the foil typically having a thickness of 0.10 mm. Each strip of aluminum foil is secured with an adhesive with the surfaces of the hollow member 11 close to it inextricably linked.
Die Streifen sind mit Hilfe von Zonen 15, die zwischen den Rippen 14 liegen, unlösbar verbunden, wobei sich die Zonen 15 im wesentlichen parallel zu den ihnen naheliegenden Oberflächen erstrecken. Die Rippen 14 auf jeder Seite jeder Zone 15 konvergieren zueinander, wodurch im wesentlichen dreieckige Sektionsdurchgangswege gebildet sind, durch welche die Kühlluft strömen kann. Wenn es vorgezogen irdg können die Rippen 14 mit parallelen Kühlschlitzen versehen werden; um eine Turbulenz und somit eine Zunahme der Wärmeübertragung zu fördern Figur 3 zeigt eine Abänderung am Kondensator nach. den Figuren 1 und 2, wobei die Streifen zwischen jedem Paar hohler Glieder 11 Seite an Seite miteinander unlösbar verbunden sind. Einige Zonen 15 jedes Streifens sind mit anderen Zonen unlösbar verbunden und einige sind mit einem Glied des einander benachbarten Paares hohler Glieder 11 verbunden. Alternativ können die von den hohlen Gliedern abgekehrten Zonen 15 parallel zu den entsprechenden anderen Zonen liegen, von diesen einen Abstand aufweisen und miteinander durch ein Klebemittel, vorzugsweise in Form von punktförmigen Klebeverbindungen verbunden sein.The strips are made with the help of zones 15 that are between the ribs 14 are inextricably linked, the zones 15 being essentially parallel to the surfaces close to them. The ribs 14 on each side of each zone 15 converge to one another, creating substantially triangular sectional passageways are formed through which the cooling air can flow. If you prefer the ribs 14 are provided with parallel cooling slots; to a turbulence and thus promoting an increase in heat transfer Figure 3 shows a change to the capacitor after. Figures 1 and 2, the strips between each pair of hollow links 11 side by side are inextricably linked. Some zones 15 of each strip are inextricably linked to other zones and some are connected to one member of the pair of hollow members 11 adjacent to each other. Alternatively, the zones 15 facing away from the hollow members can be parallel to the corresponding other zones lie, have a distance from these and each other by means of an adhesive, preferably in the form of point-like adhesive connections be connected.
In einer weiteren Konstruktion können mehr als zwei rippenbildend gefaltete Streifen vorgesehen und zwischen jedem Paar hohler Glieder 11 mittels unlçsbarer Verbindung angebracht sein.In another construction, more than two can be rib-forming folded strips are provided and between each pair of hollow members 11 by means permanent connection.
Anstatt daß die hohlen Glieder 11 an ihren Enden mittels der Teile 12 miteinander in Verbindung stehen, um ein fortlaufend wellenförmiges Rohr zu bilden, können die hohlen Glieder 11 auch getrennte bzw. einzelne Rohre sein, die an ihren beiden Enden mit Röhrenblechen oder Sammel- bzw. Verteilungseinrichtungen verbunden sind, wodurch das zu kühlende Fluid parallel durch die hohlen Glieder 11 von einem zum anderen Ende strömen kann.Instead of the hollow members 11 at their ends by means of the parts 12 communicate with each other to form a continuously undulating tube, the hollow members 11 can also be separate or individual tubes attached to their both ends connected to tubular plates or collecting or distributing devices are, whereby the fluid to be cooled in parallel through the hollow members 11 of a can flow to the other end.
Die hohlen Glieder 11 und die die Rippen 14 bildenden Streifen können aus einer Aluminiumlegierung oder jedem anderen geeigneten wärmeleitenden Material hergestellt sein.The hollow members 11 and the ribs 14 forming strips can made of an aluminum alloy or any other suitable thermally conductive material be made.
Wenn es vorgezogen wird, kann in der in Figur 3 gezeigten Ausführungsform oder ihren Abänderungen ein Metallblech oder ein Plastikmaterial zwischen den Seite an Seite liegenden gefalteten Streifen unlösbar befestigt sein, anstatt daß die Streifen unmittelbar miteinander unlösbar verbunden sind.If preferred, in the embodiment shown in FIG or Put a sheet of metal or a plastic material between the sides of your modifications Side-lying folded strips cannot be detachably attached instead of the strips are directly inextricably linked.
