Die Fließgeschwindigkeit der Flüssigkeit kann durch die Pumpe erhöht werden. wenn das Material des Kühlkörpers eine schlechte Wärmeleitfähigkeit aufweist, kann er die Wärme nicht rechtzeitig in die Flüssigkeit leiten. Das Material des Kühlkörpers ist üblicherweise Aluminium, Kupfer, Silber oder deren Legierung. Dieses Material kann jedoch nicht mehr die Kühlanforderung der Zentraleinheit mit immer höherer Leistung erfüllen.The flow rate the liquid can be increased by the pump become. if the material of the heat sink a poor thermal conductivity has, he can heat Do not pour into the liquid in time. The material of the heat sink is usually Aluminum, copper, silver or their alloy. This material However, it can no longer meet the cooling requirement the central unit with ever higher Achieve performance.
Der Diamant ist durch eine hohe Härte, eine hohe Wärmeleitfähigkeit, eine große Brechung und eine Korrosionsbeständigkeit gekennzeichnet und findet somit in der Industrie eine breite Anwendung. Der Wärmeleitungskoeffizent des Diamantes ist das Fünffache des Wärmeleitungskoeffizentes des Kupfers, insbesondere bei höherer Temperatur. Der natürliche Diamant ist sehr teuer. Daher wurden verschiedene Verfahren entwickelt, den synthetischen Diamant herzustellen. Zur Erzeugung einer Diamantschicht aus Gasen von der Kohlenwasserstoffreihe sind mehrere Verfahren bekannt, wie MPCVD (mikrowellenplasma-unterstützte Gasphasenabscheidung) und HFCVD (Hot-Filament-CVD). Dadurch kann eine polykristalline Diamantschicht erhalten werden, deren Eigenschaf ten mit denen des natürlichen einkristallinen Diamantes identisch sind.Of the Diamond is by a high hardness, a high thermal conductivity, a big Refraction and corrosion resistance characterized and thus finds in the industry a wide application. The heat conduction coefficient of the diamond is five times the Wärmeleitungskoeffizentes of copper, especially at higher Temperature. The natural one Diamond is very expensive. Therefore, different methods have been developed to produce the synthetic diamond. For producing a diamond layer from hydrocarbons are several processes known as MPCVD (microwave plasma assisted vapor deposition) and HFCVD (Hot Filament CVD). This can be a polycrystalline Diamond layer are obtained, whose properties with those of the natural monocrystalline Diamantes are identical.
Daher hat der Erfinder ein wärmleitendes Material entwickelt, das ein Metall und einen kristallinen Kohlenstoff (wie Diamant) enthält, wodurch der Wärmeleitungskoeffizient des Materials erheblich erhöht wird. In Anbetracht der Nachteile herkömmlicher Lösungen hat der Erfinder, basierend auf langjähriger Erfahrung in diesem Bereich, nach langem Studium, zahlreichen Versuchen und unentwegten Verbesserungen die vorliegende Erfindung entwickelt.Therefore the inventor has a conductive Material developed that has a metal and a crystalline carbon contains (like diamond), whereby the heat conduction coefficient material significantly increased becomes. In view of the disadvantages of conventional solutions, the inventor has based on longtime Experience in this area, after a long study, numerous experiments and unceasing improvements to the present invention.
