Description
Technisches GebietTechnical area
Die Erfindung betrifft eine Kühlvorrichtung, die die Wärmeleitwirkung der Kühlrippen und die Konvektionsgeschwindikgkeit erhöhen kann.The The invention relates to a cooling device, the the thermal conductivity the cooling fins and can increase the Konvektionsgeschwindikgkeit.
Stand der TechnikState of the art
Die Leuchtdiodenlampe enthält üblicherweise mehrere Leuchtdioden, um die Helligkeit der Glühlampe oder der Leuchtstofflampe zu erreichen. Diese Leuchtdioden sind auf einer Basisplatte gereiht, die üblicherweise eine gedruckte Schaltungsplatte ist. Die gedruckte Schaltungsplatte besitzt jedoch eine ungünstige Wärmeleitung zwischen den Leuchtdioden und dem Kühlkörper.The Light-emitting diode lamp usually contains several light-emitting diodes to the brightness of the incandescent lamp or the fluorescent lamp to reach. These light-emitting diodes are lined up on a base plate, the usual a printed circuit board is. The printed circuit board but has an unfavorable heat conduction between the light emitting diodes and the heat sink.
Dadurch kann die Wärme der Leuchtdioden in der Leuchtdiodenlampe gesammelt werden, wodurch die Helligkeit und die Lebensdauer der Leuchtdioden reduziert wird. Um dieses Problem zu lösen, ist die Basisplatte oder das Lampengehäuse mit Kühlrippen versehen, um durch die Konvektion die Wärme abzuführen.Thereby can the heat the light-emitting diodes are collected in the light-emitting diode lamp, whereby the brightness and the life of the LEDs is reduced. To solve this problem is the base plate or the lamp housing with cooling fins to pass through the convection the heat dissipate.
Da die Kühlrippen, die durch die Konvektion die Wärme abführen, üblicherweise aus Metall hergestellt sind, besitzen sie einen bestimmten Wärmeleitkoeffizient (ca. 393 W/mk und 238 W/mk von Kupfer und Aluminium). Daher ist die Kühlwirkung allein durch die Konvektion der Kühlrippen begrenzt, so dass die Wärmeableitung der Leuchtdiodenlampe nicht gewährleistet werden kann.There the cooling fins, by the convection the heat pay off, usually are made of metal, they have a certain coefficient of thermal conductivity (about 393 W / mk and 238 W / mk of copper and aluminum). thats why the cooling effect bounded solely by the convection of the cooling fins, so that the heat dissipation the light-emitting diode lamp is not guaranteed can be.
Aufgabe der ErfindungObject of the invention
Der Erfindung liegt die Aufgabe zugrunde, eine Kühlvorrichtung zu schaffen, die die Wärmeleitwirkung der Kühlrippen und die Konvektionsgeschwindikgkeit erhöhen kann.Of the Invention has for its object to provide a cooling device, the thermal conductivity the cooling fins and can increase the Konvektionsgeschwindikgkeit.
Diese Aufgabe wird durch die erfindungsgemäße Kühlvorrichtung gelöst, die umfaßt: mindestens einen Kühlrippensatz, mindestens ein starres Kühlelement, das sich in der Unterseite des Kühlrippensatzes befindet und durch die Kühlrippen erstreckt, und mindestens einen flexiblen Supraleiter, der sich durch die Kühlrippen erstreckt und an einem Ende mit dem mindestens einen starren Kühlelement zusammengelötet ist. Die Kühlrippen jedes Kühlrippensatzes weisen mindestens ein Belüftungsloch für den Luftstrom auf.These Task is solved by the cooling device according to the invention, the comprising: at least one set of cooling fins, at least one rigid cooling element, located in the bottom of the finset set located and through the cooling fins extends, and at least one flexible superconductor, which is through the cooling fins extends and is soldered together at one end with the at least one rigid cooling element. The cooling fins each finset set have at least one ventilation hole for the Airflow on.
Im flexiblen Supraleiter ist eine Arbeitsflüssigkeit gefüllt, die durch die Aggregatzustandsänderung die Wärme kontinuierlich wegtransportieren kann, ohne die Temperatur zu verändern, wodurch die Wärmeleitwirkung der Kühlrippen erhöht wird. Zudem wird die Konvektionsgeschwindigkeit durch die Belüftungslöcher der Kühlrippen erhöht.in the flexible superconductor is filled with a working fluid by the state of aggregation the heat can continuously transport away without changing the temperature, causing the heat conducting the cooling fins elevated becomes. In addition, the convection speed through the ventilation holes of the cooling fins elevated.
