Abstract

The invention relates to a profiled sidewall (2) comprising a lamellae support for lamellar tubular heat exchangers which are used particularly as condensers and recirculation coolers and are provided with a housing comprising profiled sidewalls, end walls, and elements that support fans and enclose a heat exchanger block (5). Said heat exchanger block encompasses heat exchanger tubes (7) with lamellae or cooling fins that are supported thereupon. The heat exchanger block (5) rests on monolithic hollow profiled cross beams (3) in which the profiled sidewalls (2) are fixed. Said cross beams (3) extend substantially along the entire length of the lamellar tubular heat exchanger, are disposed on both sides of the heat exchanger, and extend from one end of the profiled sidewalls (2) to the other.

Description

Seitenwandprofil mit Lamellenabstützung für Lamellenrohrwärmetauscher Side wall profile with lamella support for finned tube heat exchanger
Die Erfindung betriffl ein Seitenwandprofil mit Lamellenabstützung fiir Lamellenronrwärme- austauscher der in der DE 101 11 384 beschriebenen Art.The invention relates to a side wall profile with lamella support for Lamellenronrwärme- exchanger of the type described in DE 101 11 384.
Das bekannte Wärmetauschergehäuse weist Seitenwandproffle auf, die u.a. den Wärmetauscher- block mit seinen Lamellen tragen, jedoch hinsichtlich, ihrer Biegesteifigkeit nur beschränkt belastbar sind, so dass in der Regel mehrere solcher Seitenwandprofile hintereinander angeordnet oder miteinander verbunden werden müssen, um Gehäuselängen von beispielsweise 10 m zu verwirklichen.The known heat exchanger housing has Seitenwandffoffle, the u.a. carry the heat exchanger block with its fins, but in terms of their bending stiffness are limited load, so that usually several such sidewall profiles must be arranged one behind the other or connected to each other to realize housing lengths of for example 10 m.
Die Aufgabe der Erfindung besteht darin, die Festigkeit der Seitenwandprofile und ihreThe object of the invention is the strength of the sidewall profiles and their
Tragfähigkeit so zu erhöhen, dass auch größere als die bisher üblichen Profillängen aus einem Stück verbaut werden können, um den Wärmetauscherblock zu tragen.To increase load capacity so that even larger than the usual profile lengths can be installed in one piece to carry the heat exchanger block.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass der Wärmetauscherblock auf sich über im Wesentlichen die gesamte Länge des Lamellenrohrwärmetauschers erstreckenden, einteiligen, zu beiden Seiten des Wärmetauschers angeordneten Hohlprofiltraversen abgestützt ist, die das Gewicht der Seitenwandprofile mit allen von diesen gehaltenen Elementen, insbesondere den Wärmetauscherblock mit seinen Lamellenrohren, tragen und sich von einem Ende der Seitenwandprofile zum anderen erstrecken. Erfindungsgerαäß werden also die beiden parallelen Seitenwandprofile des LarneUenronrwärnie- tauschers an sich, bekannter Bauart mit Hilfe von Hohlprofiltraversen verstärkt und versteift. Diese Hohlprofiltraversen sind mit den Seitenwandprofilen verbindbar, so dass sie die in letztere eingeleiteten Kräfte aufnehmen, ohne dass die Seitenwandprofile sieb, unter der Belastung insbesondere des Wärmetauscherblocks verformen, dessen Baulänge auf diese Weise erheblich vergrößert werden kann, wenn größere Wäπneaustauscherflächen benötigt werden.This object is achieved in that the heat exchanger block is supported on substantially over the entire length of the finned tube heat exchanger, one-piece, arranged on both sides of the heat exchanger hollow profile traverses that the weight of the side wall profiles with all held by these elements, in particular the heat exchanger block its finned tubes, and extend from one end of the sidewall profiles to the other. Erfindungsgerαäß therefore the two parallel side wall profiles of the LarneUenronrwärnie- exchanger amplified per se, known design using hollow profile traverses and stiffened. These hollow profile rails are connected to the side wall profiles, so that they absorb the forces introduced in the latter, without the side wall profiles sie, deform under the load, in particular the heat exchanger block whose length can be significantly increased in this way, if larger Wäπneaustauschauscherflächen are needed.

Das Wärmetauschergehäuse 9 und insbesondere der Wärnietauscherblock 5 mit den Hohlprofiltraversen 3 wird auf Füßen 10 getragen, wie beispielsweise aus Fig. 4 ersichtlich, die so bemessen sind, dass ihre Länge die durch den Pfeil gekennzeichnete Luftansaugung durch die Ventilatoren 11 des Luflkühlers, in dem der Wärmetauscherblock 5 Verwendung findet, nicht behindert.On the outer sides of the hollow profile trusses 3, the same side wall profiles 2 are fixed and together with the hollow profile trusses 3 closed side walls 8 of the finned tube heat exchanger, as shown in FIG. The heat exchanger housing 9 and in particular the Wärnietauscherblock 5 with the hollow profile trusses 3 is supported on feet 10, as shown for example in FIG. 4, which are dimensioned so that their length the indicated by the arrow air intake through the fans 11 of Luflkühlers in which the heat exchanger block 5 is used, not hindered.
Die Hohlprofiltraversen (3) sind als kastenförmige oder U-förmige Profile ausgebildet und, wie aus Fig. 2 ersichtlich, mit einem verlängerten Schenkel (12) des Seitenwandprofils verbunden. The hollow profile traverses (3) are formed as box-shaped or U-shaped profiles and, as shown in FIG. 2, connected to an extended leg (12) of the side wall profile.
