Description

Rückkühler für Transformatorenöl in Form eines Kaminkühlers Es ist bereits vorgeschlagen worden, bei Rückkühlern für Transformatorenöl, welche nachArt eines Kaminkühlers ,ausgebildet sind, zur Erhöhung der Kühlwirkung das Kühlröhrensystem nur in einer einzigen quer zur Strömungsrichtung des Kühlmittels stehenden Reihe derart anzuordnen, daß jedes Teilchen des Kühlmittels nur ein Kühlrohr berühren kann.Recooler for transformer oil in the form of a chimney cooler It is has already been proposed for dry coolers for transformer oil, which according to Art a chimney cooler, the cooling pipe system to increase the cooling effect only in a single row transverse to the direction of flow of the coolant to be arranged so that each particle of the coolant touch only one cooling tube can.

Durch die Erfindung wird die Kühlwirkung bei Rückkühlern der oben beschriebenen Art dadurch ganz wesentlich erhöht, daß das für die Verdunstungskühlung erforderliche Wasser nicht einfach von oben nach unten rieselt, sondern, daß unterhalb der Kühlröhren Spritz-oder Zerstäubungsdüsen für das Kühlwasser angeordnet sind und von außen in den Kühlkörper zusätzliche Kühlluft eingeführt wird, die durch das Kühlwasser eine Abkühlung erfährt, bevor sie die Röhren berührt. Die mit Wassernebel gesättigte Kühlluft wird dann an den Kühlköi-pei-n vorbeistreichen und die Oberfläche mit einer feinen, schnell verdunstenden Haut überziehen. Die Wirkungsweise ist in diesem Falle die denkbar beste, weil man in der Lage ist, durch Einstellung der aus den Düsen gespritzten Wassermenge gerade so viel Wasser zuzugeben, als die dem Kühler zu entziehende Wärmemenge verdunsten kann. Dadurch wird die Anwendung einer Wasserumlaufpumpe, wie sie die bisher bekannten Kühlanlagen nötig haben, überflüssig.With the invention, the cooling effect in drycoolers becomes the above described type is increased very significantly that the evaporative cooling Required water does not simply trickle down from the top, but that below the cooling tubes spray or atomizing nozzles for the cooling water are arranged and additional cooling air is introduced into the heat sink from the outside, through the cooling water is cooled before it touches the tubes. The ones with water mist Saturated cooling air will then brush past the cooling coils and the surface cover with a fine, rapidly evaporating skin. The mode of action is in in this case the best possible because one is able to adjust the add just as much water as the amount of water sprayed out of the nozzles The amount of heat to be extracted from the cooler can evaporate. This makes the application of a Water circulation pump, as required by the previously known cooling systems, is superfluous.

Ein entsprechendes Ausführungsbeispiel ist in der Zeichnung dargestellt.A corresponding embodiment is shown in the drawing.
