Description

Es sind Wärmeaustauschapparate bekannt, die aus einem geteilten Gehäuse mit in der Teilungsebene schlangenförmig oder serpentinartig verlaufendem, längsgeteiltem Kanal und in diesem mit Wandabstand angeordneter, lose eingelegter und bequem herausnehmbarer sowie in gleichem Sinne, wie der Kanal gebogener Rohrschlange bestehen. Die Röhrschlange durchdringt mit ihren EndenThere are heat exchange apparatuses known, which consist of a split housing with in the Partition plane serpentine or serpentine running, longitudinally divided channel and in this one arranged at a distance from the wall, loosely inserted and easily removable as well as in the same sense as the channel consists of a curved pipe coil. the Tubular snake penetrates with its ends

ίο das Gehäuse, und die Gehäusehälften besitzen an den dafür geeigneten Stellen die Anschlußstutzen für die Zu- und Ableitung des den Zwischenraum zwischen Kanalwand und äußerer Rohirschlangenwand durchströmenden Mediums, ζ. B. des Kühlwassers. Es ist, insbesondere bei Kondensatoren, auch bekannt, den Durchflußquersclinitt der Rohrschlange nach dem Ausfluß zu- zu verjüngen. Auch Einlagen in der Schlange sind bereits vorgeseihen worden, durch welche ringförmige DurdhfLußquerschnitte entstehen und weichte die Bildung von unbeeinfiußbaren Flüssigkeitskernen verhindern sowie das Auseinanderziehen der Flüssigkeit in dünne Schichten bezwecken sollen. Diese bekannten Apparate besitzen den Vorteil, daß sie bequem zerlegt und gründlich! gereinigt werden können. Bei Rohren mit Einlagen besteht aber die Schwierigkeit der Einbringung und Herausnahme derselben. Außerdem verursachen die Einlagen eine zu rasdhie Verstopfung und Inkrustierung.ίο own the housing and the housing halves the connection pieces for the inlet and outlet of the flowing through the space between the canal wall and the outer pipe wall Medium, ζ. B. the cooling water. It is also known, especially in the case of capacitors, to taper the flow cross-section of the pipe coil after the outflow. Even Deposits in the queue have already been provided, through which ring-shaped Through flow cross-sections arise and give way to the formation of uninfluenceable cores of liquid as well as the purpose of pulling the liquid apart into thin layers. These known devices have the advantage that they are easily disassembled and thoroughly! can be cleaned. In the case of pipes with inlays, however, there is the difficulty of introducing and removing them the same. In addition, the deposits cause excessive clogging and incrustation.

Demgegenüber besteht das Wesen der vorliegenden Erfindung darin, daß sidh der Querschnitt der Rohrschlange vom Eintritt in das Gehäuse bis zum Austritt aus demselben nicht nur in bezug auf den Durchfluß selbst verjüngt, sondern auchi in der Form verändert, derart, daß er sidhi nach dem Austritt 1Zu allmählich verflacht und schließlich ganz flach-In contrast, the essence of the present invention is that the cross section of the coil from the entry into the housing to the exit from the same not only tapers with respect to the flow itself, but also changes in shape, such that it is changed after the exit 1 Too gradually flattened and finally completely flat-

Hereby 'it is achieved that the condensate, the closer it is to the cooling water inlet - comes, in - ever thinning layer is exposed to it. the Heat exchange effect is done in this way, bypassing the difficulties as well the shortcomings of the pipes with inserts significantly improved.

Die Zeichnung veranschaulicht ein Ausführungsbeispiel der Erfindung als Kondensator. The drawing illustrates an embodiment of the invention as a capacitor.

Der Querschnitt der Rohrschlange e verändert sich gemäß der Erfindung in doppeltem Sinne, vom Eintritt in den Kühlwasserkanal bis zu ihrem Austritt aus demselben. Zunächst verjüngt sich der freie Durchflußquerschnitt als solcher nach dem Rohraustritt hin, und dann geht er von der runden in die völlig flachgedrückte Form über. In dem flachen Querschnitt wird das Kondensat in dünnen Schicht auseinanderge? zogen der Einwirkung des dort am kältesten Kühlwassers ausgesetzt und eine erheblich günstigere Austauschwirkung erzielt. Der zu kondensierende Dampf tritt oben in die Rohrschlange ein und unten als Kondensat aus. Das Kühlwasser nimmt seinen Weg von unten nach oben im Gegenstrom dazu. Die Anschlüsse für letzteres erfolgen an den seitlichen Stutzen C und d des Gehäuses.be provided. The same can sit in the same way on the outside of the pipe wall itself. The cross section of the coil e changes according to the invention in two ways, from the entry into the cooling water channel to its exit from the same Pipe outlet, and then it changes from the round shape to the completely flattened shape. In the flat cross-section, the condensate is pulled apart in a thin layer and exposed to the action of the coldest cooling water there and a considerably more favorable exchange effect is achieved. The steam to be condensed occurs at the top of the pipe coil and at the bottom as condensate. The cooling water takes its way from bottom to top in countercurrent. The connections for the latter are made at the side connections C and d of the housing.

Der beschriebene Apparat soll besonders als Kondensator Verwendung finden, kann aber in geeigneten Fällen auch anderen Zwekken dienen.The apparatus described is intended to be used, in particular, as a condenser but also serve other purposes in appropriate cases.
