Description
Die vorliegende Erfindung betrifft ein Kühlsystem für ein elektronisches Gerät und ein elektronisches Gerät damit, insbesondere ein Computer.The present invention relates a cooling system for a electronic device and an electronic device with it, especially a computer.
Nach dem Stand der Technik sind heutige Kühlsysteme auf der Basis von Luftkühlung aufgebaut, die zur Verstärkung der Kühleffektivität mit Lüftern konstruiert sind. Um die Lautstärke der Lüfter zu verringern und um eine bessere Zirkulation des Kühlmediums zu erreichen gibt es seit einigen Jahren Wasserkühlungssysteme.According to the state of the art today's cooling systems based on air cooling built that to reinforce of cooling efficiency with fans constructed are. To the volume the fan reduce and for a better circulation of the cooling medium There have been water cooling systems for several years now.
Beispielsweise ist ein Wasserkühlungs-System, das ohne einen Lüfter für den Kühler auskommt, beschrieben in der Zeitschrift ct „Leise dank Wasser oder Heatpipes", veröffentlicht am 20.10.2003, Ausgabe 22, Heise Zeitschriften Verlag, Hannover mit Verweis auf www.xice.de. Dort wird ein Kühlsystem für ein elektronisches Gerät vorgestellt mit mindestens einem wärmeabgebenden Bauteil und einem Kühlkreislauf, in dem ein flüssiges Kühlmittel über einen Wärmetauscher zur Aufnahme der von mindestens einem Bauteil abgegebenen Wärme und einem Kühler zur Abgabe der Wärme an die Atmosphäre zirkuliert. Bei derartigen Kühlsystemen wird die Zirkulation des Kühlmittels durch eine elektrisch angetriebene Pumpe angeregt.For example, a water cooling system, that without a fan for the cooler comes out, described in the magazine ct "Quiet thanks to water or heat pipes", published on 20.10.2003, issue 22, Heise Zeitschriften Verlag, Hannover with reference to www.xice.de. There, a cooling system for an electronic device is presented with at least one heat-emitting Component and a cooling circuit, in which a liquid Coolant over one heat exchangers for receiving the heat emitted by at least one component and a cooler to give off the heat circulated to the atmosphere. In such cooling systems will the circulation of the coolant excited by an electrically driven pump.
Die bisherigen wassergekühlten Systeme haben den Nachteil, dass der technische Aufwand sehr hoch ist. Die Pumpe darf nicht durch Luftblasen gestört werden, da sonst die Zirkulation zum Erliegen kommen und sogar die Pumpe zerstört werden könnte. Dieser Umstand bringt wiederum mit sich, dass mit einem geschlossenen Drucksystem gearbeitet und ein Druckausgleichsgefäß benötigt wird, das auch als Luftabscheider dient. Durchaus können diese Systeme mehrere elektronische Bauteile kühlen, da die Pumpe genügend Kapazität hat. Für mehrere elektronische Bauteile wäre ein kompliziertes Regelwerk notwendig, um den Zirkulationsstrom auf die unterschiedliche Abwärme der Bauteile einzustellen.The previous water-cooled systems have the disadvantage that the technical complexity is very high. The pump must not be disturbed by bubbles otherwise the circulation will come to a standstill and even the Pump destroyed could be. This circumstance in turn implies that with a closed Pressure system worked and a pressure equalization vessel is needed which also serves as an air separator. Quite simply, these systems can do several things cool electronic components because enough for the pump capacity Has. For several electronic components would be a complicated set of rules necessary to the circulation flow on the different waste heat to adjust the components.
Die Aufgabe der vorliegenden Erfindung ist es, ein Kühlsystem für ein elektronisches Gerät bereitzustellen, welches geräuscharm und energiesparend ist und so die oben beschriebenen Nachteile vermeidet.The object of the present invention is it, a cooling system for a electronic device to provide, which is quiet and saves energy and thus avoids the disadvantages described above.
Erfindungsgemäß wird diese Aufgabe durch ein Kühlsystem mit den Merkmalen des Patent-Anspruchs 1 gelöst. Durch die Anregung der Zirkulation des Kühlmittels durch Konvektion wird der Lärm und Energieverbrauch der Pumpe vermieden.According to the invention this object is achieved by a cooling system solved with the features of patent claim 1. By the suggestion of Circulation of the coolant convection causes the noise and energy consumption of the pump avoided.
Dieses System hat weiterhin den Vorteil, dass die Abwärme der zu kühlenden Bauteile die Zirkulation der Kühlflüssigkeit für jeden Wärmetauscher individuell bestimmt, ohne dass dafür zusätzliche Technik wie Pumpen, Druckbehälter, Wasser- bzw. Luftabscheider usw. zur Steuerung der Kühlung gebraucht wird. Die Konvektion fordert ein freies Auf- und Absteigen der Kühlflüssigkeit, daher spielen Luftblasen keine Rolle, da diese ungehindert aufsteigen können. Damit kann das Kühlsystem offen und drucklos sein und entlastet die kühlflüssigkeitsführenden Bauteile bezüglich ihrer Druckfestigkeit.This system also has the advantage that the waste heat the one to be cooled Components the circulation of the cooling liquid for each Individual heat exchanger certainly without that additional technology like pumps, pressure vessels, Used water or air separator, etc. for controlling the cooling becomes. Convection calls for a free rise and fall of the coolant, Therefore, air bubbles play no role, as they can rise unhindered. In order to can the cooling system be open and depressurized and relieves the coolant-carrying components with respect to their Compressive strength.
