Description
Die Erfindung betrifft einen modularen Wärmetauscher nach dem Oberbegriff des Anspruches 1.The The invention relates to a modular heat exchanger according to the preamble of claim 1.
Wärmetauscher sind Vorrichtungen, die Wärme von einem Medium mit höherer Temperatur an ein Medium niedrigerer Temperatur ableiten. Für eine effektive Wärmeableitung und Abgabe der Wärme an kühlere Medien ist eine möglichst große Austauschfläche erforderlich. Zu diesem Zweck weisen die Kühlkörper der Wärmetauscher vielfach ein Rippenprofil auf. In Abhängigkeit von der bezweckten Anwendung sind unterschiedliche technische Ausführungen von Wärmetauschern bekannt. Hierzu sind auch Wärmetauscher aus einer Schaumstruktur, insbesondere aus Metallschaum, seit längerem in vielfältiger Weise bekannt.heat exchangers are devices that heat from a medium with higher Derive temperature to a medium of lower temperature. For an effective heat dissipation and release of heat to cooler Media is one as possible size exchange area required. For this purpose, the heat sinks of the heat exchanger often have a rib profile on. Dependent on of the intended application are different technical designs of heat exchangers known. These are also heat exchangers From a foam structure, in particular metal foam, for a long time in many ways known.

Wesentliche Nachteile der Wärmetauscher gem. dem Stand der Technik sind, die relativ schlechte Wärmeleitfähigkeit von Schaumstrukturen, gepaart mit vergleichsweise großen Abmessungen.basics Disadvantages of heat exchangers acc. In the prior art, the relatively poor thermal conductivity of foam structures, coupled with comparatively large dimensions.
Der Erfindung liegt die Aufgabe zugrunde, die Nachteile des Standes der Technik zu beseitigen. Insbesondere sollen Wärmetauscher geschaffen werden, die auf Grund einer verbesserten Wärmeleitfähigkeit und einem höheren Wärmefluss eine kleinere Dimensionierung erlauben und sich durch eine nachhaltig kürzere Reaktionszeit auf Temperaturschwankungen der Wärmequelle auszeichnen.Of the Invention is based on the object, the disadvantages of the prior art to eliminate the technology. In particular, heat exchangers are to be created, due to improved thermal conductivity and higher heat flow allow a smaller sizing and sustain through a sustainable shorter Distinguish reaction time to temperature fluctuations of the heat source.
Diese Aufgabe wird durch die Merkmale des Hauptanspruchs gelöst, demgemäß nichtporöse, wärmeleitende Elemente in eine offenporige Schaumstruktur eingebettet werden. Zweckmäßige Ausgestaltungen der Erfindung ergeben sich aus den nachfolgenden Ansprüchen.These The object is solved by the features of the main claim, accordingly non-porous, heat-conducting Elements are embedded in an open-pore foam structure. Advantageous embodiments The invention will become apparent from the following claims.
Der erfindungsgemäße Wärmetauscher besteht aus einem oder mehreren Wärmeverteilern, die von einer offenporigen Schaumstruktur umgeben und mit dieser verbunden sind. Die Zellen, welche die Schaumstruktur bilden, sind untereinander vernetzt sowie chaotisch geformt und strukturiert.Of the inventive heat exchanger consists of one or more heat spreaders, one of which surrounded by open-cell foam structure and are connected to this. The cells that make up the foam structure are among themselves networked and chaotically shaped and structured.
Der Erfindung liegt der Gedanke zugrunde, in die Schaumstruktur nichtporöse, wärmeleitende Elemente einzulagern, die als Leitflächen oder Leitstäbe ausgebildet sind. Hierzu ist in einer bevorzugten Ausführungsform die Schaumstruktur aus mehreren, voneinander getrennten Segmenten zusammengesetzt, wobei die wärmeleitenden Elemente, die Leitflächen und/oder Leitstäbe, im Inneren der Segmente liegen oder die Leitflächen eine einseitige Bewandung der Segmente bilden. Die eingelagerten Leitflächen und/oder die Leitstäbe sind mit der Schaumstruktur und/oder den Wärmeverteilern festsitzend, vorzugsweise stoffschlüssig verbunden. Als Fügetechnik kommt Galvanisieren, Löten, Schweißen oder ein Gießverfahren zur Anwendung, wobei die Schaumstruktur, die genannten wärmeleitenden Elemente und in einer weiteren bevorzugten Ausführungsform, die Wärmeverteiler in einem Stück gegossen sind.The invention is based on the idea to incorporate into the foam structure non-porous, heat-conducting elements which are formed as guide surfaces or guide rods. For this purpose, in a preferred embodiment, the foam structure is composed of a plurality of mutually separated segments, wherein the heat-conducting elements, the guide surfaces and / or guide rods lie in the interior of the segments or the guide surfaces form a one-sided Verwandung the segments. The embedded guide surfaces and / or the guide rods are fixed to the foam structure and / or the heat spreaders, preferably materially connected. The joining technique is electroplating, soldering, welding or a casting method for use, wherein the foam structure, said heat-conducting elements and in another preferred embodiment, the heat spreaders are cast in one piece.
Der erfindungsgemäße Wärmetauscher zeichnet sich im Vergleich zum Stand der Technik durch einen nachhaltig effizienteren, namentlich vervielfachten Wärmefluss aus. Überraschend wurde festgestellt, dass der Wärmefluss des erfindungsgemäßen Wärmetauschers im Vergleich zu bisherigen Wärmetauschern mit Schaumstruktur, jedoch ohne wärmeleitende Leitflächen und Leitstäbe, um den Faktor zwei bis fünf erhöht ist.Of the inventive heat exchanger draws Compared to the state of the art, by a sustainably more efficient, in particular multiplied heat flow out. Surprised it was found that the heat flow the heat exchanger according to the invention compared to previous heat exchangers with foam structure, but without thermally conductive fins and guide rods, by a factor of two to five elevated is.
