Abstract

A heat exchanger tube made from metal has thick regions which vary in the circumferential direction. Optimum heat exchange is achieved with respect to the dimensions when the heat exchanger tube is constructed from a metal tube (1), which has a constant wall thickness and bores (2) in the lateral surface, and from metal pins (3) which are mounted in the bores (2) in the lateral surface and project both inwards and outwards. <IMAGE>

Description

Die Erfindung betrifft ein Wärmetauscherrohr aus Metall, mit in Um­ fangsrichtung variierenden Dickenbereichen.The invention relates to a heat exchanger tube made of metal, with in order thickness ranges varying in the direction of capture.

Wärmetauscherrohre der genannten Art sind in den verschiedensten Aus­ führungsformen bekannt. Meistens handelt es sich um Rippenrohre, deren äußere Längsrippen die unterschiedlichsten Formen aufweisen können. Auch Rohre oder Profile mit rippenähnlichen Konturen auf der lnnen­ seite, wie sie beispielsweise durch Drehen oder Ziehen von Rohren oder ähnlichen Profilen erzeugt werden können, sind bekannt. Allen diesen Rohren ist gemeinsam, daß bei vorgegebenen Rohraußenabmessungen die für den Wärmetausch zur Verfügung gestellte Außen- bzw. lnnenfläche nicht optimal ist.Heat exchanger tubes of the type mentioned are in a variety of ways known forms of management. Mostly there are finned tubes, their outer longitudinal ribs can have a wide variety of shapes. Even pipes or profiles with rib-like contours on the inside side, such as by turning or pulling pipes or Similar profiles can be created are known. All of these Pipes have in common that for given pipe dimensions external or internal surface made available for heat exchange is not optimal.

Der Erfindung liegt die Aufgabe zugrunde, ein gattungsgemäßes Wärme­ tauscherrohr so auszubilden, daß bei einfacher Herstellbarkeit ver­ gleichsweise große Außen- und lnnenmantelflächen für den Wärmetausch zur Verfügung stehen.The invention has for its object a generic heat Exchanger tube so that ver with simple manufacturability equally large outer and inner surface areas for heat exchange be available.

Zur Lösung dieser Aufgabe ist das erfindungsgemäße Wärmetauscherrohr durch ein konstante Wandstärke aufweisendes Metallrohr mit Mantelboh­ rungen gekennzeichnet, in denen sowohl nach innen als auch nach außen vorkragende Metallstifte befestigt sind.To solve this problem, the heat exchanger tube according to the invention due to a constant wall thickness of metal pipe with jacket boring marked in which both inside and outside cantilevered metal pins are attached.

Die durch die Erfindung erreichten Vorteile bestehen darin, daß die aus dem Metallrohr nach innen und außen vorkragenden Metallstifte dem Wärmetauscherrohr insgesamt eine vergleichsweise große Zusatzfläche für den Wärmetausch zur Verfügung stellen. Dabei ist das erfindungsgemäße Wärmetauscherrohr verhältnismäßig einfach fertigbar, da keine beson­ deren Profile u. dgl. erforderlich sind. The advantages achieved by the invention are that the protruding from the metal tube inwards and outwards metal pins Heat exchanger tube overall a comparatively large additional area for provide the heat exchange. Here is the invention Heat exchanger tube relatively easy to manufacture, because none whose profiles u. Like. are required.  

Für die weitere Ausgestaltung bestehen im Rahmen der Erfindung mehrere Möglichkeiten. Grundsätzlich kann das Metallrohr beliebigen Querschnitt aufweisen; vorzugsweise weist das Metallrohr jedoch einen kreiszylin­ drischen Querschnitt auf und verlaufen die Mantelbohrungen radial. Zu besonders guten Ergebnissen kommt man in diesem Zusammenhang, wenn die Mantelbohrungen und Metallstifte einerseits gegenüberliegend, ande­ rerseits mit vorgegebenem Längsabstand voneinander um 90° zueinander versetzt angeordnet sind. Jedenfalls hat man es über die Zahl und Größe bzw. Form der Metallstifte in der Hand, die Wärmetauschflächen dem jeweiligen Bedarf anzupassen. lnsgesamt ergibt sich immer ein Wärmetauscherrohr mit minimalen Abmessungen, so daß die entsprechen­ den Wärmetauscher sehr kompakt gebaut werden können. Die Metallstifte können durch Schweißen oder Hartlöten mit dem Metallrohr verbunden sein.There are several for the further configuration within the scope of the invention Opportunities. Basically, the metal tube can have any cross section exhibit; however, the metal tube preferably has a circular cylinder cross section and the jacket holes run radially. To one gets particularly good results in this context if the casing bores and metal pins on the one side, the other on the other hand with a predetermined longitudinal distance from each other by 90 ° to each other are staggered. Anyway you have it about the number and Size or shape of the metal pins in the hand, the heat exchange surfaces to adapt to the respective need. Overall, there is always one Heat exchanger tube with minimal dimensions so that they correspond the heat exchanger can be built very compact. The metal pins can be connected to the metal pipe by welding or brazing be.

Im folgenden wird die Erfindung anhand einer ein Ausführungsbeispiel darstellenden Zeichnung mit einer einzigen Zeichnungsfigur näher er­ läutert.The invention is based on an exemplary embodiment performing drawing with a single drawing figure closer he purifies.

Das in der Figur dargestellte Wärmetauscherrohr aus Metall ist mit in Umfangsrichtung variierenden Dickenbereichen versehen. Zu diesem Zweck ist zunächst ein Metallrohr 1 mit konstanter Wandstärke vorgesehen. Dieses Metallrohr 1 weist Mantelbohrungen 2 auf, in denen sowohl nach innen als auch nach außen vorkragende Metallstifte 3 befestigt sind, wodurch sich insgesamt in Umfangsrichtung und in Längsrichtung des Wärmetauscherrohres variierende Dickenbereiche ergeben.The metal heat exchanger tube shown in the figure is provided with thickness ranges varying in the circumferential direction. For this purpose, a metal tube 1 with a constant wall thickness is initially provided. This metal tube 1 has jacket bores 2 , in which metal pins 3 projecting both inwards and outwards are fastened, which results in varying thickness ranges overall in the circumferential direction and in the longitudinal direction of the heat exchanger tube.

Das Metallrohr 1 weist im Ausführungsbeispiel einen kreiszylindrischen Querschnitt auf und die Mantelbohrungen 2 verlaufen radial. Die Man­ telbohrungen 2 und Metallstifte 3 sind zunächst jeweils paarweise gegen­ überliegend angeordnet. Diese Paare sind aber andererseits auch mit einem vorgegebenen Längsabstand voneinander um 90° zueinander ver­ setzt angeordnet. Das erkennt man ohne weiteres aus der Figur. ln dieser ist auch angedeutet, daß die kreiszylindrischen Metallstifte 3 durch Schweißen oder Hartlöten mit dem Metallrohr 1 verbunden sind.In the exemplary embodiment, the metal tube 1 has a circular cylindrical cross section and the casing bores 2 run radially. The man telbohrungen 2 and metal pins 3 are initially arranged in pairs opposite each other. On the other hand, these pairs are also arranged at a predetermined longitudinal distance from one another by 90 ° to one another. You can easily see that from the figure. This also indicates that the circular cylindrical metal pins 3 are connected to the metal tube 1 by welding or brazing.
