Abstract
Eine Wärmesenke ist offenbart. Die Wärmesenke weist eine Basis (102, 402) mit zumindest eine Dampfkammer (208, 408) auf, die ein Fluid mit einem ersten Aktivierungspunkt enthält. Die Basis hat zumindest eine Dampfkammer (212, 412), die ein Fluid mit einem zweiten Aktivierungspunkt enthält. Der erste Aktivierungspunkt ist anders als der zweite Aktivierungspunkt.A heat sink is disclosed. The heat sink has a base (102, 402) with at least one vapor chamber (208, 408) which contains a fluid with a first activation point. The base has at least one vapor chamber (212, 412) that contains a fluid having a second activation point. The first activation point is different from the second activation point.
Description
Hintergrundbackground
Computersysteme und Server erzeugen große Mengen an Wärme. Ein beträchtlicher Teil der Wärme, der an diesen Systemen erzeugt wird, kommt von einzelnen elektronischen Komponenten, die in den Systemen untergebracht sind, beispielsweise den zentralen Verarbeitungseinheiten (CPU). Eine Wärmesenke ist typischerweise an den Komponenten befestigt, um dazu beizutragen, die Wärme zu entfernen, die durch die Komponente erzeugt wird. Da sich die Chipdichten der Komponenten erhöht haben, hat sich auch die Wärme erhöht, die durch die Komponenten erzeugt wird.Computer systems and servers generate large amounts of heat. A significant portion of the heat generated at these systems comes from individual electronic components housed in the systems, such as the central processing units (CPU). A heat sink is typically attached to the components to help remove the heat generated by the component. As the chip densities of the components have increased, so has the heat generated by the components.
Einige Komponenten arbeiten bei unterschiedlichen Leistungspegeln, abhängig von den Stromanforderungen des Systems. Wenn die Komponente bei voller Leistung arbeitet, kann dieselbe große Mengen an Wärme erzeugen. Wenn dieselbe bei niedriger Leistung arbeitet oder wenn dieselbe in einem Standby-Betriebsmodus ist, kann die erzeugte Wärmemenge im Vergleich zu dem Hochleistungszustand beträchtlich reduziert sein. Das Entwickeln einer Wärmesenke, die die Wärme unter allen Betriebsbedingungen der Komponente effizient entfernt, ist zu einer Herausforderung geworden.Some components operate at different power levels, depending on the system power requirements. When the component is operating at full power, it can generate large amounts of heat. When operating at low power or when in a standby mode of operation, the amount of heat generated may be significantly reduced compared to the high power state. Developing a heat sink that efficiently removes heat under all operating conditions of the component has become a challenge.

Beim Betrieb, wenn die Komponente
Das zweite Fluid in den zwei sekundären Dampfkammern
Bei einem beispielhaften Ausführungsbeispiel der Erfindung können die Fluide in der ersten und zweiten Dampfkammer unterschiedliche Arbeitsfluide mit unterschiedlichen Siedepunkten sein. Beispielsweise kann das Fluid in der ersten Dampfkammer Wasser sein und das Fluid in den sekundären Dampfkammern kann Alkohol sein. Bei einem weiteren beispielhaften Ausführungsbeispiel der Erfindung können die Fluide in der ersten und den zweiten Dampfkammern das gleiche Arbeitsfluid sein, aber die unterschiedlichen Dampfkammern können mit unterschiedlichen Volumen und Drücken des Fluids gefüllt sein, um den Siedepunkt der Fluide in den unterschiedlichen Dampfkammern einzustellen, damit dieselben bei unterschiedlicher Leistung und Temperatur aktivieren. Bei einem weiteren beispielhaften Ausführungsbeispiel der Erfindung können die unterschiedlichen Dampfkammern eindeutige Oberflächenbehandlungen und/oder Dochtwirkungsstrukturen aufweisen, die die Aktivierungspunkte der Fluide modifizieren, die in der Dampfkammer enthalten sind. Bei einem beispielhaften Ausführungsbeispiel der Erfindung kann der erste Aktivierungspunkt in dem Bereich von 35–65 Grad Celsius sein, und der zweite Aktivierungspunkt kann in dem Bereich von 60–80 Grad Celsius sein.In an exemplary embodiment of the invention, the fluids in the first and second steam chambers may be different working fluids having different boiling points. For example, the fluid in the first steam chamber may be water and the fluid in the secondary steam chambers may be alcohol. In another exemplary embodiment of the invention, the fluids in the first and second vapor chambers may be the same working fluid, but the different vapor chambers may be filled with different volumes and pressures of the fluid to adjust the boiling point of the fluids in the different vapor chambers to be the same activate at different power and temperature. In another exemplary embodiment of the invention, the different vapor chambers may have unique surface treatments and / or wicking structures that modify the activation points of the fluids contained within the vapor chamber. In an exemplary embodiment of the invention, the first activation point may be in the range of 35-65 degrees Celsius, and the second activation point may be in the range of 60-80 degrees Celsius.
Die Wärmesenke
Bei einigen beispielhaften Ausführungsbeispielen der Erfindung kann die erste Dampfkammer in mehr als ein Volumen unterteilt sein.
Bei einigen beispielhaften Ausführungsbeispielen der Erfindung kann die zu kühlende Komponente mehr als zwei unterschiedliche Leistungspegel haben. Beispielsweise kann die Komponente einen Standby-Modus haben, einen Niedrigleistungsbetriebspunkt und einen Hochleistungsbetriebspunkt. Bei diesem beispielhaften Ausführungsbeispiel der Erfindung kann es drei oder mehr Dampfkammern mit unterschiedlichen Siede- oder Aktivierungspunkten geben. Beispielsweise kann in
