Aufgabe der Erfindung ist es, einen Wärmetauscher der eingangs genannten Art vorzuschlagen, bei dem die Wärme, die vom Kondensor abgegeben wird, auf möglichst kurzem Wege an das Wärmeträgermedium abgegeben wird und gleichzeitig das Wärmetauscherrohr preisgünstig herstellbar ist.The object of the invention is a heat exchangers to propose of the type mentioned, in which the heat, the is released by the condenser to the heat transfer medium in the shortest possible way is given and at the same time the heat exchanger tube can be produced inexpensively is.
Gelöst ist die Aufgabe durch die Maßnahmen des Anspruchs 1. Weitere vorteilhafte Ausgestaltungen sind in den Unteransprüchen beschrieben.The task is solved by the Measures of the Claim 1. Further advantageous embodiments are described in the subclaims.
Das oder die Sammlerrohr/e ist/sind durch das Innenhochdruck-Umformen derart gestaltet, dass sich ein optimaler Strömungsquerschnitt im Verlauf des Rohres ergibt. Der Materialaufwand ist durch die Verwendung von Rohren oder Profilrohren minimiert. Im Verlauf des Sammlerrohres sind mindestens zwischen den Anbindungen für die Kondensoren Vertiefungen in das Sammlerrohr derart eingedrückt, dass die Flächenzahl des Strömungsquerschnitts im Bereich der Anbindungen in etwa der Flächenzahl des Strömungsquerschnitts im Bereich der Vertiefungen entspricht. Damit ist eine weitgehend gleichbleibende Flächenzahl des Strömungsquerschnitts im Verlauf des Rohres erreicht, wodurch die Masse des Wärmeträgermediums minimiert ist und der Wärmeübergang durch die dünne Wandung des Sammlerrohres im Bereich der Anbindung erfolgt.The collector pipe (s) is / are by hydroforming designed in such a way that there is an optimal flow cross-section in the course of the pipe results. The cost of materials is due to the use minimized by pipes or profile pipes. In the course of the collector pipe there are recesses at least between the connections for the condensers pressed into the collector tube in such a way that the number of areas of the flow cross section in the area of the connections approximately the area number of the flow cross-section in the area of the depressions. This is largely the same space index of the flow cross section reached in the course of the tube, creating the mass of the heat transfer medium is minimized and the heat transfer through the thin Wall of the collector pipe in the area of the connection is made.
Abweichungen ergeben sich funktionsbedingt beispielsweise in den Bereichen zwischen den Vertiefungen und den Anbindungen, wo eine starke Materialverformung erforderlich ist. Zur Optimierung des Strömungsquerschnitts und der Flächenzahl des Strömungsquerschnitts und der Flächenzahl des Strömungsquerschnitts im Verlauf des Sammlerrohrs können an verschiedenen Stellen Vertiefungen oder auch erhabene Bereiche angeordnet sein. Abweichungen von der ähnlichen Flächenzahl können in Bereichen starker Umformung des Rohres oder Rohrquerschnitts vorliegen.Deviations result from the function for example in the areas between the wells and the Connections where strong material deformation is required. To optimize the flow cross-section and the number of areas of the flow cross section and the number of areas of the flow cross section in the course of the collector tube at various points, wells or raised areas be arranged. Deviations from the similar number of areas can occur in areas of strong deformation of the pipe or pipe cross-section.
Herstellungsbedingt durch das Innenhochdruck-Umformverfahren, bei dem aus einem Rohr oder Rohrprofil die endgültige Form erstellt ist, ist die Anbindung, über die die Wärmeübertragung vom Kondensor auf den Wärmetauscher erfolgt, einseitig offen. Die Rohre oder Rohrprofile ähneln in ihrer Form möglichst dem gewünschten Profil des Sammlerrohres. Das Profil kann aus runden und eckigen Bereichen bestehen. In einer vorteilhaften Ausgestaltung ist die Anbindung bis auf den offenen Bereich weitgehend zylindrisch ausgeführt. Vorteilhaft ist weiterhin, wenn die Anbindung den Kondensor um mehr als 180° mit einem Hinterschnitt umfasst.Production-related through the hydroforming process, in which the final shape is created from a pipe or pipe profile the connection, about which is the heat transfer from the condenser to the heat exchanger done, open on one side. The pipes or pipe profiles are similar in their shape if possible the desired one Profile of the collector pipe. The profile can consist of round and angular areas consist. The connection is in an advantageous embodiment largely cylindrical except for the open area. Advantageous is still if the connection of the condenser by more than 180 ° Undercut includes.
Zur weiteren besseren Fixierung sowie Wärmeübertragung sind die Kondensoren durch ein Blech oder eine Klammer, die mit dem Sammlerrohr in Verbindung steht, in die Anbindungen gedrückt. Das Blech und/oder die Klammern sind dabei in einer vorteilhaften Weise in eine Nut des Sammlerrohrs eingelegt oder in die Vertiefungen.For further better fixation as well heat transfer are the condensers by a sheet or a bracket that with the collector pipe is connected, pressed into the connections. The Sheet metal and / or the brackets are in an advantageous manner placed in a groove of the collector tube or in the recesses.
