fflirnberg, 24. 10. 1961 Wärmeaustauscher mit Doppelringspalt-Eohrsystemenfflirnberg, October 24, 1961 Heat exchangers with double ring gap pipe systems

Die Erfindung bezieht sich auf einen Wärmeaustauscher mit je von drei konzentrischen Rohren oder von zwei konzentrischen Kehren und einem Kernstab gebildeten Doppelringepalt-Rohrsystenien. Derartige Doppelringspalt-Vvärmeaustauecher eignen sich vornehmlich für kleine Durehflußmengen, also für wertvolle Wärmeträger, da durch kleine Spaltweiten relativ hohe Strömungsgeschwindigkeiten und damit ein guter Wärmeübergang erreicht werden können. Außerdem wird durch die kleinen hydraulischen Durchmesser, die bei solchen Ringspalten erzielt werden können, die Wärmeübertragung erheblich besser als in Kreisquerschnitten. Der Wärmeübergang und der Druckverlust sind bei der Strömung in Doppelringquerschnitten stark abhängig von der Eotationssymmetrie der j Strömungsquerschnitte. Um die Eotationssymmetrie der RingThe invention relates to a heat exchanger with three concentric tubes or two concentric tubes Bends and a core rod formed double ring gap pipe systems. Such double ring gap Vwärmeaustauecher are primarily suitable for small Durehflusszüge, so for Valuable heat transfer medium, since relatively high flow speeds due to the small gap widths and thus good heat transfer can be achieved. In addition, due to the small hydraulic diameter that occurs in such annular gaps can be achieved, the heat transfer significantly better than in circular cross-sections. The heat transfer and the pressure loss are strongly dependent on the eotation symmetry of the flow in double ring cross-sections j flow cross-sections. To the eotation symmetry of the ring

Die Anbringung solcher Zentriermittel ist mit einem hohen !•iaterial- und Pertigungsaufwand verbunden. Außerdem wird durch die Zentriermittel der -Jtrömurigswiderstand in de^i Rohrsystem vergrößert.Cross-sections to be adhered to are on the ears and the core rod Centering cams, sticks, sheets or similar. intended. The attachment of such centering means is associated with a high level of material and manufacturing costs. Also will through the centering means of the -Jtrömurigswiderstanderstand in the pipe system enlarged.

Art der Zentrierung erfordert keinen besonderen Materialaufwand. Die Herstellung der Zentrierung ist einfach, da dae mittlere Rohr durch ein einfaches Preßwerkzeug in die gewünschte Form gedrückt werden kann. Es b-aucht nur ein Rohr Je Rohrsystem behandelt zu werden, während bei den bekannten Nocken oder Stiften mindestens zwei Rohre bearbeitet werden müssen. Die Zentrierung mittels des gepreßten Zwischenrohres bietet der Strömung keinen Formwiderstand* Die Einbuße an auläesiger Innendruckbeanspruchung ist nur unwesentlich geringer als bei kreisförmigem Querschnitt des mittleren Rohres.The type of centering does not require any special material expenditure. The production of the centering is easy, since the middle tube can be inserted into the desired one by means of a simple pressing tool Shape can be pressed. There is also only one pipe per pipe system to be dealt with, while the known ones Cams or pins at least two tubes need to be machined. The centering by means of the pressed intermediate tube offers the flow no form resistance * The loss of external The internal pressure load is only insignificantly lower than with a circular cross-section of the central tube.
