Description
Technisches Gebiettechnical area
Die Erfindung betrifft einen Kühlkörper, der unterschiedliche Metalle enthält.The The invention relates to a heat sink, the different Contains metals.
Die Betriebswärme der elektronischen Bauelemente (wie Zentraleinheit) muß abgeführt werden, um eine Beschädigung der elektronischen Bauelemente durch thermischen Runaway und thermische Beanspruchung zu vermeiden. Dafür ist ein Kühlsystem erforderlich.The operating heat the electronic components (such as central unit) must be dissipated to a damage electronic components through thermal runaway and thermal stress to avoid. Therefore is a cooling system required.
Zu diesem Zweck werden üblicherweise die folgenden vier Kühlungen verwendet: 1. zwangsläufige Luftkühlung, 2. natürliche Luftkühlung, 3. Phasenänderungskühlung und 4. Kühlmittelkühlung. Am häufigsten wird die Kombination von einem Kühlventilator für zwangsläufige Luftkühlung und einem Kühlkörper aus Kühlrippen eingesetzt. Der Kühlkörper weist wegen der Kühlrippen eine größere Wärmeabfuhrfläche auf und gibt die Wärme in die Umgebungsluft ab. Daher hat der Kühlkörper eine hohe Arbeitsstabilität und Arbeitssicherheit. Da dieser Kühlkörper üblicherweise aus Aluminium oder Kupfer hergestellt ist, besitzt er niedrige Herstellungskosten und hohe Wärmeleitfähigkeit und läßt sich leicht bearbeiten.To this purpose will be common the following four coolings used: 1. inevitable Air cooling, 2. natural Air cooling, 3. phase change cooling and 4. Coolant cooling. Most frequently becomes the combination of a cooling fan for positive air cooling and a heat sink cooling fins used. The heat sink points because of the cooling fins a larger heat dissipation surface and gives the heat into the ambient air. Therefore, the heat sink has a high work stability and occupational safety. As this heatsink usually Made of aluminum or copper, it has low production costs and high thermal conductivity and lets himself go edit easily.
Der Kühlkörper aus Aluminium hat eine niedrigere Wärmeleitfähigkeit und eine höhere Wärmeabgabefähigkeit, während der Kühlkörper aus Kupfer eine höhere Wärmeleitfähigkeit und eine niedrigere Wärmeabgabefähigkeit hat. Zudem ist der Kühlkörper aus Kupfer teurer als der Kühlkörper aus Aluminium.Of the Heat sink off Aluminum has a lower thermal conductivity and a higher one Heat dissipation ability while the heat sink off Copper a higher one thermal conductivity and a lower heat releasing ability Has. In addition, the heat sink is off Copper more expensive than the heat sink Aluminum.

Aufgabe der ErfindungObject of the invention
Der Erfindung liegt die Aufgabe zugrunde, einen Kühlkörper zu schaffen, dessen Bodenplatte und Kühlrippen mit mindestens einem Wärmeleiter verbunden sind, der lokal über diese verteilt wird, wobei das Material des Wärmeleiters anders ist als das der Bodenplatte und der Kühlrippen und die Materialien vorzugsweise Metalle sind, um die Wärmleitwirkung des Kühlkörpers zu erhöhen.Of the Invention has for its object to provide a heat sink, the bottom plate and cooling fins with at least one heat conductor connected locally over this is distributed, the material of the heat conductor is different than that the bottom plate and the cooling fins and the materials are preferably metals to provide the thermal conductivity of the Heat sink too increase.
Der Erfindung liegt eine weitere Aufgabe zugrunde, einen Kühlkörper zu schaffen, wobei der Wärmeleiter scheibenförmig, drahtförmig oder netzförmig in der Bodenplatte und den Kühlrippen angeordnet ist, um die Wärmeleitfläche zu vergrößern, damit die Wärmeleitwirkung erhöht wird. Der Wärmeleiter kann auch kornförmig, wabenförmig, punktmatrixförmig, speichenförmig, spiralförmig, konzentrisch, spinnennetzförmig oder unregelmäßig (nicht dargestellt) ausgebildet sein.Of the Another object of the invention is to provide a heat sink create, with the heat conductor disc-shaped, wire form or reticulated in the bottom plate and the cooling fins is arranged to increase the heat conduction surface so that the thermal conductivity elevated becomes. The heat conductor can also be granular, honeycomb, dot matrix shape, spoke-like, spirally concentric, cobweb-shaped or irregular (not represented).
Diese Aufgaben werden durch den erfindungsgemäßen Kühlkörper gelöst, der mindestens eine Bodenplatte umfaßt, auf der eine Vielzahl von Kühlrippen gebildet sind, dadurch gekennzeichnet, daß die Bodenplatte und die Kühlrippen mit mindestens einem Wärmeleiter verbunden sind, der lokal angeordnet ist, wobei die Bodenplatte und die Kühlrippen aus einem ersten Metall hergestellt sind, während der Wärmeleiter aus einem anderen zweiten Metall hergestellt ist, und wobei die Wärmeleitfähigkeit des zweiten Metalls höher ist als die des ersten Metalls.These objects are achieved by the heat sink according to the invention comprising at least one bottom plate on which a plurality of cooling fins are formed, characterized in that the bottom plate and the cooling fins are connected to at least one heat conductor, which is arranged locally, wherein the bottom plate and the Cooling fins are made from a first metal, while the heat conductor from another second Metal is prepared, and wherein the thermal conductivity of the second metal is higher than that of the first metal.
Der Wärmeleiter ist lokal innerhalb und/oder außerhalb der Bodenplatte und der Kühlrippen angeordnet. D.h. der Wärmeleiter ist in der Bodenplatte und den Kühlrippen eingebettet oder mit der Bodenplatte und den Kühlrippen verrastet, wodurch der Wärmeleiter über diese verteilt wird. In einem bevorzugten Ausführungsbeispiel sind die Wärmeleiter mit einem Abstand parallel oder nicht parallel oder gekreuzt angeordnet.Of the heat conductor is local within and / or outside the bottom plate and the cooling fins arranged. That the heat conductor is in the bottom plate and the cooling fins embedded or locked with the bottom plate and the cooling fins, thereby the heat conductor over this is distributed. In a preferred embodiment, the heat conductors arranged at a distance parallel or not parallel or crossed.
