Abstract

Kondensator (20) welches besonders dafür geeignet ist in Kondensatoren eingesetzt zu werden, die mit Betriebsdrücken von etwa 20 bar betrieben werden. Ein Kondensator ist insbesondere ein sogenannter Flachrohrkondensator, bei dem zwischen Sammelrohren (21,22) Rohre (10) mit im wesentlichen flachen Querschnitt verlaufen, zwischen denen wiederum Kühlrippen (23) angeordnet sind, die sich an den flachen Oberflächen der Rohre (10) abstützen.Capacitor (20) which is particularly suitable for use in capacitors be operated with operating pressures of about 20 bar. A capacitor is in particular a so-called flat tube capacitor, in between the manifolds (21,22) tubes (10) with im substantially flat cross-section, between which in turn Cooling ribs (23) are arranged, which are supported on the flat surfaces of the tubes (10).

Erfindungsgemäß hat ein Rohr (10) einen im wesentlichen flachen Querschnitt und mehrere nebeneinander angeordnete Strömungskanäle (11). Die Strömungskanäle (11) sind im wesentlichen rund und haben einen hydraulischen Durchmesser von 1,10mm bis 1,30mm. Eine weiter vorteilhafte Wirkung erzielt ein Rohr (10) mit Strömungskanälen (11), die einen hydraulischen Durchmesser von 1,14mm bis 1,26mm aufweisen und weiter bevorzugt ist ein Durchmesser von 1,18mm bis 1,22mm. Die besten Ergebnisse erzielt ein Rohr (10) mit einem hydraulischem Durchmesser von etwa 1,20mm.According to the invention, a tube (10) has a substantially flat cross-section and a plurality of juxtaposed flow channels (11). The Flow channels (11) are essentially round and have a hydraulic Diameter from 1.10mm to 1.30mm. A further advantageous effect Achieves a tube (10) with flow channels (11), the hydraulic Diameter of 1.14mm to 1.26mm and is more preferred a diameter of 1.18mm to 1.22mm. The best results achieved a pipe (10) with a hydraulic diameter of about 1.20mm.

Weiter wurde gefunden, dass Rohre (10) mit flachem Querschnitt und runden, in Reihe angeordneten Strömungskanälen (11) von besonders vorteilhafter Wirkung in Mäanderstromkondensatoren (20) arbeiten.

Furthermore, it has been found that tubes (10) with a flat cross-section and round flow channels (11) arranged in series operate with particularly advantageous effect in meander flow capacitors (20).
