Abstract
Description
Mikrokomponenten mit Kanälen für flüssige und gasförmige Stoffe werden für chemische Reaktionen mit sehr geringen Massenströmen verwendet. Sie bestehen in der Regel aus mehreren strukturierten plattenförmigen Substraten. Die Substrate können aus Metall, Glas, Silizium, Kunststoff oder anderen Materialien bestehen. Die Strukturen beinhalten Geometrien, welche vielfältige chemische, physikalische und biologische Reaktionen begünstigen. Durch hermetisch dichtes Fügen der einzelnen Substrate werden die Strukturen verschlossen. Eine derart gefertigte Komponente besteht aus mindestens zwei Substraten.Microcomponents with channels for liquid and gaseous Fabrics are made for chemical reactions with very low mass flows are used. They exist usually from several structured plate-shaped substrates. The substrates can made of metal, glass, silicon, plastic or other materials consist. The structures contain geometries, which are diverse chemical, favor physical and biological reactions. By hermetically sealed Joining the The structures are sealed to individual substrates. Such a manufactured component consists of at least two substrates.
Schwierigkeiten bestehen in der Zuführung und Abführung der Prozeßmedien. Technologien, wie sie im Apparatebau vorherrschen, wie z.B. Verschraubungen oder das Anbringen von Flanschen zur Befestigung von Rohren, sind aufgrund der mechanischen und thermischen Eigenschaften der verwendeten Materialien nicht praktikabel.Difficulties exist in feeding and removal the process media. Technologies that are prevalent in apparatus construction, such as fittings or attaching flanges to attach pipes due to the mechanical and thermal properties of the used Materials not practical.
Das vorgestellte Anschlußsystem besteht im wesentlichen aus einer oberen und einer unteren Anschlußkupplung, einem Bolzen und einem Gegenstück. Die anzuschließende Mikrokomponente besitzt an mindestens einer definierten Stelle eine Durchgangsbohrung. Diese stellt die Verbindung zu den Kanalstrukturen im inneren der Komponente dar. Die Komponente besteht in der Regel aus mehreren Ebenen. Die Strukturen der einzelnen Ebenen können durch verschiedene Strukturierungsverfahren der Mikrotechnik hergestellt werden. Durch anschließendes hermetisch dichtes Verbinden der Ebenen werden die Kanalstrukturen verschlossen. Auf die verschiedenen anzuwendenden Fertigungsverfahren kommt es hier nicht an. Zur Verbindung besitzt die untere Anschlusskupplung (Bolzen) ein Bolzengewinde und die oberen Anschlusskupplung (Gegenstück) ein dazu passendes Muttergewinde. Neben der Verschraubung sind auch andere lösbare kraft- und formschlüssige und unlösbare Verbindungsarten verwendbar (Bajonettverschluß, Exenter, Keilverbindung, Schnappverschluß oder Kleben und andere). Das Bolzengewinde wird durch die Durchgangsbohrung gesteckt und mit dem Muttergewinde der oberen Anschlusskupplung verschraubt. Zusätzlich verfügt die obere Anschlusskupplung noch über eine Anschlussmöglichkeit für gängige Anschlüsse für Flüssigkeiten oder Gase aus der z. B. Medizin, Chemie oder Biotechnologie. Dies sind in der Regel metrische oder zöllige Gewinde und Bajonettverschlüsse.The presented connection system consists essentially of an upper and a lower connection coupling, a bolt and a counterpart. The one to be connected Microcomponent has a through hole at at least one defined point. This establishes the connection to the channel structures inside the Component. The component usually consists of several levels. The structures of the individual levels can be structured using various structuring methods Microtechnology. By subsequent hermetically sealed connection of the levels, the channel structures are closed. To the different The manufacturing processes to be used are not important here. For connection the lower connection coupling (bolt) has a bolt thread and the upper connection coupling (counterpart) has a matching nut thread. In addition to the screw connection, other releasable non-positive and positive connections unsolvable Connection types can be used (bayonet lock, eccentric, wedge connection, Snap lock or Gluing and others). The bolt thread is through the through hole inserted and with the nut thread of the upper connection coupling screwed. additionally has the upper connection coupling still over a connection option for common connections for liquids or gases from the z. B. Medicine, chemistry or biotechnology. This are usually metric or imperial threads and bayonet locks.
Als Dichtfläche kann das obere Muttergewinde (bei Rohrgewinde), eine obere Dichtfläche oder eine innenliegende Dichtfläche für innendichtende Anschlüsse verwendet werden. Parallel zu den Oberflächen der Mikrokomponente befinden sich Dichtflächen, welche das Innere der Anschlusskupplung nach außen abdichten. Der Stoffstrom gelangt über das obere Muttergewinde durch eine Bohrung in den Verbindungskanal der unteren Anschlusskupplung in die Kanalstruktur.The upper nut thread can be used as a sealing surface (with pipe thread), an upper sealing surface or an internal one sealing surface used for internal sealing connections become. Parallel to the surfaces The microcomponent has sealing surfaces that cover the inside of the Connection coupling to the outside caulk. The material flow passes through the upper nut thread through a hole in the connection channel of the lower connection coupling into the channel structure.
