Abstract
Description
Die Erfindung bezieht sich auf einen Wärmetauscher, insbesondere für Brennkraftmaschinen, mit Schalensegmenten, die vorzugsweise an den Endbereichen miteinander in Verbindung stehende Sammelräume aufweisen, und mit zumindest zwei Anschlussstutzen, wobei die Schalensegmente von einem ersten Medium, insbesondere Kühlmittel, und zwischen den Schalensegmenten gebildete Strömungskanäle von einem zweiten Medium, insbesondere Kühlluft, durchströmt sind.The The invention relates to a heat exchanger, in particular for internal combustion engines, with shell segments, preferably at the end regions with each other related collection rooms have, and with at least two connecting pieces, wherein the shell segments from a first medium, in particular coolant, and between the Tray segments formed flow channels of one second medium, in particular cooling air, flows through are.
Ein
derartiger Wärmetauscher
ist aus der
Bei nur geringen Durchflussmengen an Kühlmittel kann die erforderliche Kühlleistung oft nur mit überproportional vergrößerten Wärmetauschern realisiert werden. Eine deutliche Verbesserung des Wärmeübergangs würde mit höheren Strömungsgeschwindigkeiten erreicht. Höhere Strömungsgeschwindigkeiten können durch höhere Durchflussmengen erreicht werden. Diese höheren Durchflussmengen würden aber den Einsatz von leistungsfähigeren Pumpen und eine entsprechende Anpassung der Strömungsleitungen erfordern.at only small flow rates of coolant can be the required cooling capacity often only with disproportionate enlarged heat exchangers will be realized. A significant improvement in the heat transfer would with higher flow rates reached. higher flow rates can through higher Flow rates can be achieved. But these higher flow rates would the use of more powerful Require pumps and a corresponding adjustment of the flow lines.
Der Erfindung liegt die Aufgabe zugrunde, einen gattungsbildenden Wärmetauscher so zu verbessern, dass er mit verschiedenen Strömungsgeschwindigkeiten bei zumindest weitgehend unveränderten Durchflussmengen ohne wesentliche bauliche Änderungen durchströmt werden kann.Of the Invention is based on the object, a generic heat exchanger so as to improve it with different flow velocities at least largely unchanged Flow rates are flowed through without significant structural changes can.
Diese Aufgabe wird dadurch gelöst, dass in den Schalensegmenten zwischen den Endbereichen zumindest je eine Trennwand vorgesehen ist. Vorzugsweise reicht die Trennwand bis in den Sammelraum des einen Endbereichs und teilt auch diesen in zwei Teilräume auf.These Task is solved by that in the shell segments between the end regions at least each a partition is provided. Preferably, the partition extends into the plenum of one end area and also shares this in two subspaces on.
Durch diese Ausgestaltung kann der Zu- und Ablauf des Kühlmittels so gesteuert werden, dass es zuerst den einen Teil, vorzugsweise auf der Kühlluftaustrittsseite, die die Schalensegmente des Wärmetauschers quer durchströmt, geleitet wird und dann im zweiten Schritt den zweiten Teil auf der Kühllufteintrittsseite durchströmt. Es können auch je nach Wärmetauschergröße zwei oder mehr Trennwände vorgesehen werden, sodass eine mehrfache Umkehr erfolgt. Es handelt sich dabei um das Prinzip der Kreuzgegenstrom-Durchströmung.By This configuration can be the inlet and outlet of the coolant be controlled so that it is the first part, preferably on the cooling air outlet side, the shell segments of the heat exchanger flows through, and then in the second step the second part on the Cooling air inlet side flows through. It can also depending on the heat exchanger size two or more partitions provided become a multiple reversal. These are to the principle of cross-countercurrent flow.
Der Wärmeübergang wird durch höhere Strömungsgeschwindigkeiten, insbesondere höhere Turbulenzen, erhöht, wozu innerhalb der Schalen der Schalensegmente Vorsprünge, Vertiefungen und dergleichen angeordnet sind. Die vorgeschlagene Durchströmung führt bei der jeweiligen Strömungspassage zu größeren Temperaturunterschieden zwischen erstem und zweitem Medium, was zu einer verbesserten Kühlleistung führt.Of the Heat transfer is due to higher flow rates, especially higher turbulences, elevated, for which within the shells of the shell segments projections, depressions and the like are arranged. The proposed flow leads the respective flow passage to larger temperature differences between the first and second medium, resulting in improved cooling performance leads.
Vorzugsweise ist die Trennwand in den Schalensegmenten und den Sammelräumen mittig angeordnet und halbiert die inneren Strömungsquerschnitte.Preferably the partition is arranged centrally in the shell segments and the collecting spaces and halves the internal flow cross sections.
Die Trennwand wird vorzugsweise durch eine Rippe in einer Schale der Schalensegmente gebildet, die im Wesentlichen dichtend mit einer zweiten Schale in Verbindung steht. Diese Rippe wird insbesondere durch eine Prägung in der Schale erzeugt. Vorzugsweise sind in beiden Schalen Rippen beziehungsweise Prägungen vorgesehen, die einander gegenüberstehen und dichtend miteinander verbunden, vorzugsweise verlötet, sind.The Partition is preferably by a rib in a shell of the Shell segments are formed, which are substantially sealing with a second shell communicates. This rib will in particular by an imprint produced in the shell. Preferably, ribs are in both shells or imprints provided, which face each other and sealingly connected, preferably soldered, are.
Die Trennwand kann aber auch als getrenntes Bauteil hergestellt werden und in zumindest einer Rille einer ersten Schale angeordnet und im Wesentlichen dichtend mit einer zweiten Schale in Verbindung stehen. Es kann natürlich auch in jeder Schale je eine Rille vorgesehen sein, in die die Trennwand eingesetzt ist.The Partition can also be made as a separate component and arranged in at least one groove of a first shell and essentially sealingly connected to a second shell stand. It can, of course also be provided in each shell depending on a groove into which the partition used is.
In weiterer Ausgestaltung weist der erfindungsgemäße Wärmetauscher nicht nur an dem Sammelraum mit den Teilräumen, sondern vorzugsweise auch auf dem gegenüberliegenden Sammelraum einen Anschlussstutzen auf, so dass bei Bedarf die Schalensegmente, wie aus dem Stand der Technik bekannt, nur in einer Richtung durchströmt werden können, kreuzweise zu dem zweiten Medium. Dabei können dann die entsprechenden Anschlussstutzen an dem Sammelraum mit den Teilräumen zu einem Anschlussstutzen zusammengefasst werden. Die Art der Durchströmung der Schalensegmente wird also durch entsprechende Anordnung oder Schaltung der Anschlussstutzen bestimmt.In Another embodiment, the heat exchanger according to the invention not only at the collecting space with the subspaces, but preferably also on the opposite plenum one Connecting piece on, so that if necessary, the shell segments, such as known from the prior art, to be flowed through in one direction only can, crosswise to the second medium. It can then the appropriate Connecting piece at the collecting space with the subspaces to a connecting piece be summarized. The type of flow through the shell segments is So by appropriate arrangement or circuit of the connection piece certainly.
Zur Verbesserung des Wärmeübergangs zwischen den Schalensegmenten sind dort vorzugsweise Turbolatoren angebracht.to Improvement of the heat transfer between The shell segments are preferably mounted there turbulators.
