Description

In dem Patent 878357 ist ein Kreuzstromwärmeaustauscher beschrieben, welcher aus mehreren kurzen und flachen, Rohren zusammengesetzt ist, welche dazwischenliegende düsenartige Kanäle bilden.In the patent 878357 a cross-flow heat exchanger is described, which is composed of several short and flat tubes, which are in between form nozzle-like channels.

Es hat sich nun gezeigt, daß die Ausbildung dieser Rohre für die Fertigung des Wärmeaustauschers von besonderer Bedeutung ist. Aus diesem Grunde wird vorgeschlagen, den Wärmeaustauscher nach dem Hauptpatent aus mehreren untereinander gleichen, austauschbaren flachgedrückten Rohren zusammenzusetzen, welche durch Punktschweißen od. dgl. miteinander verbunden sind. Diese Rohre weisen, in Längsrichtung gesehen, einen doppelschaufel.förmigen Querschnitt auf. Durch diese Anordnung ist es möglich, mehrere derartige Rohre aneinanderzureihen und je nach Anzahl derselben einen beliebig großen Wärmeaustauscher zu konstruieren. Durch die besondere Formgebung der Rohre ist es, weiterhin möglich, ohne besondere Zutaten zwei einander sich kreuzende Rohrsysteme herbeizuführen und die in dem Hauptpatent geschilderte Wirkung zu erzielen.It has now been shown that the training of these pipes for manufacturing of the heat exchanger is of particular importance. For this reason it is suggested that the heat exchanger according to the main patent from several identical, interchangeable Assemble flattened pipes, which od by spot welding. The like. With each other are connected. Seen in the longitudinal direction, these tubes have a double-blade shape Cross-section on. This arrangement makes it possible to string several such pipes together and, depending on the number of these, to construct a heat exchanger of any size. Due to the special shape of the tubes, it is still possible without special Ingredients to bring about two intersecting pipe systems and those in the main patent to achieve the effect described.

Die Erfindung ist in der Zeichnung beispielsweise veranschaulicht. Sie zeigt mehrere aufeinandergereihte Rohre im Schnitt.The invention is illustrated in the drawing, for example. It shows several pipes lined up in a section.

Der Wärmeaustauscher besteht aus den Rohren. i, welche untereinander gleich und austauschbar sind. Die Rohre i werden zweckmäßig aus geschlossenen Rohren .gefertigt und durch Punktschweißen öd. dgl. miteinander verbunden. Sie sind in ihrer Längsrichtung doppelschaufelförmig ausgebildet und an ihren Berührungsflächen mit Ansätzen z versehen, durch welche die düsenförmigen Zwischenräume 3 gebildet werden. Mehrere derartige Rohre können zu einem blockähnlichen Wärmeaustauscher zusammengefaßt werden, wobei das eine der Wärmeaustauschmittel innerhalb der Rohre i und das andere durch die Zwischenräume 3 strömt. Durch die plattenähnliche Ausbildung der Rohre i ist es möglich, bei kleinstem Raum- und Gewichtsbedarf ein Höchstmaß von Wärmeaustausch zu erzielen, so daß der Wärmeaustauscher insbesondere für Heizzwecke in kleinen. Räumen. (Kabinenheizung od. dgl.) geeignet ist.The heat exchanger consists of the tubes. i, which among each other are the same and interchangeable. The tubes i are expediently made up of closed tubes .made and by spot welding öd. Like. Interconnected. They are in their longitudinal direction is designed in the shape of a double blade and at their contact surfaces provided with lugs z through which the nozzle-shaped spaces 3 are formed will. Several such tubes can form a block-like heat exchanger be summarized, with one of the heat exchange means within the tubes i and the other flows through the spaces 3. Due to the plate-like training With the tubes i it is possible to achieve a maximum with the smallest space and weight requirement of heat exchange to achieve, so that the heat exchanger in particular for heating purposes in small. Clearing. (Cabin heating or the like.) Is suitable.
