Description

Doppelrohrwärmeaustauschvorrichtung für Kältemaschinen mit einer Mehrzahl von Innenrohren. Es ist bereits bekannt, bei Doppelrohrwärmeaustauschapparaten für Kälteerzeugungsanlagen zur Erzielung großer Leistung eine Mehrzahl von Innenrohren in einem gemeinsamen Außenrohr anzuordnen. Werden hierbei in der bisher bekannten Weise Rohre von kreisförmigem Querschnitt verwendet, so treten infolge der ungünstigen Querschnittsverteilung tote Strömungskerne zwischen Innenrohren und Außenrohr auf, welche .den Wärmeaustausch beeinträchtigen. Um diesen Nachteil zu beseitigen, soll gemäß der Erfindung das Außenrohr als Profilrohr ausgebildet werden, wobei sein Querschnitt so gewählt wird, daß es sich möglichst eng der durch die Gesamtanordnung der Innenrohre gegebenen Umgrenzungslinie anschließt. Die Innenrohre können hierbei kreisförmigen Querschnitt haben oder gleichfalls in an sich bereits bekannter Weise als Profilrohr beliebigen Querschnittes ausgebildet sein.Double tube heat exchanging device for refrigerating machines with a plurality of inner pipes. It is already known in double tube heat exchangers for Refrigeration systems to achieve high performance a plurality of inner tubes to be arranged in a common outer tube. Are here in the previously known Way tubes of circular cross-section are used, so occur as a result of the unfavorable Cross-sectional distribution of dead flow cores between inner tubes and outer tube, which. affect the heat exchange. To eliminate this disadvantage, should according to the invention, the outer tube can be designed as a profile tube, being Cross-section is chosen so that it is as close as possible to the overall arrangement the inner pipes given boundary line connects. The inner tubes can do this have a circular cross-section or likewise in a manner already known per se be designed as a profile tube of any cross-section.

Die Abb. i bis 3 zeigen einige Ausführungsbeispiele, bei welchen der Querschnitt des Außenrohres i demjenigen der Innenrohre 2 möglichst weitgehend angepaßt ist, so daß nahezu längs der gesamten Rohrflächen ein gleichmäßiger Wärmeaustausch stattfinden kann.Figs. I to 3 show some embodiments in which the Cross-section of the outer tube i matched to that of the inner tubes 2 as largely as possible is, so that almost uniform heat exchange along the entire tube surface can take place.
