Abstract
Description
Die Erfindung betrifft ein Verfahren zum Herstellen von Plattenstapeln, insbesondere zum Herstellen von aus wenigstens einem Plattenstapel bestehenden Kühlern oder Kühlerelementen oder Wärmesenken gemäß Oberbegriff Patentanspruch 1.The The invention relates to a method for producing plate stacks, in particular for the production of at least one plate stack existing coolers or radiator elements or heat sinks according to the generic term Claim 1.
Speziell zum Kühlen von elektrischen Bauteilen oder Modulen, insbesondere auch solchen mit hoher Leistung, sind bereits Kühler, auch Mikrokühler bekannt, die aus miteinander zu einem Stapel verbundenen dünnen Platten aus Metall (Metallfolie) bestehen und von denen die im Stapel innen liegenden Platten derart strukturiert, d. h. mit Öffnungen oder Durchbrüchen versehen sind, daß sich im Inneren des Plattenstapels bzw. Kühlers Kühlkanäle oder Strömungswege für ein Kühlmedium bilden. Zum flächigen Verbinden der Platten sind diese an ihren Fügeflächen, d.h. an ihren Oberflächenseiten mit einem Fügemittel versehen. Für das Fügen bzw. Verbinden werden die Platten dann zu dem Plattenstapel übereinander gestapelt und anschließend auf eine entsprechende Prozeßtemperatur erhitzt, bei der unter Verwendung des Fügemittels an den Fügeflächen ein schmelzflüssiger Metallbereich (Verbindungs- oder Schmelzschicht) erzeugt wird, so daß nach dem Abkühlen die Platten zu dem Plattenstapel miteinander verbunden sind.specially for cooling of electrical components or modules, especially those with high performance, coolers, even micro coolers are already known the thin plates joined together to form a stack made of metal (metal foil) and of those in the stack inside lying plates structured such d. H. with openings or breakthroughs are provided that form inside the plate stack or cooler cooling channels or flow paths for a cooling medium. For surface bonding the plates are these at their joining surfaces, i. on their surface sides with a joining agent Mistake. For the joining The boards are then stacked on top of each other stacked and then to a corresponding process temperature heated, with the use of the joining agent at the joining surfaces of a molten metal area (Fusion or melt layer) is generated, so that after the cooling down the plates are connected to the plate stack.
Nachteilig bei dem bekannten Verfahren ist, daß sich im Inneren des Stapels am Übergang zwischen Durchbrüchen und Öffnungen zweier benachbarter Platten beim Erstarren der Verbindungs- oder Schmelzschicht in dieser Schicht Einschnürungen bzw. unerwünschte Hohl- oder Toträume bilden, die u.a. bei einem von dem Plattenstapel gebildeten Kühler zu unerwünschten Verwirbelungen in einem den Kühler durchströmenden Kühlmittel führen usw.adversely in the known method is that in the interior of the stack at the transition between breakthroughs and openings two adjacent plates during solidification of the connecting or enamel layer in this layer constrictions or undesirable Hollow or dead spaces form, the u.a. in a cooler formed by the plate stack undesirable Vortexes in a cooler flowing through coolant to lead etc.
Aufgabe der Erfindung ist es, ein Verfahren aufzuzeigen, welches diese Nachteile vermeidet. Zur Lösung dieser Aufgabe ist ein Verfahren entsprechend dem Patentanspruch 1 ausgebildet.task The invention is to provide a method which has these disadvantages avoids. To the solution This object is a method according to the claim 1 formed.
