Der Erfindung liegt daher die Aufgabe zugrunde, im Hinblick auf die Perfektionierung von Kühlkörpern eine Kühlkörper-Struktur zu schaffen, bei der die Wärmeübertragungsgeschwindigkeit erhöht ist, um eine schnellere und effizientere Wärmeabführwirkung zu erzielen.Of the The invention is therefore based on the object with regard to Perfecting heat sinks one Heat sink structure to create at the rate of heat transfer elevated is to achieve a faster and more efficient heat dissipation effect.
Diese Aufgabe wird erfindungsgemäß gelöst durch eine Kühlkörper-Struktur nach Anspruch 1. Weiterbildungen der Erfindung sind in den abhängigen Ansprüchen angegeben.These The object is achieved by a heat sink structure according to claim 1. Further developments of the invention are specified in the dependent claims.
Der erfindungsgemäße Kühlkörper umfasst einen mittigen Wärmeleitungskörper, der mehrere Kühlrippen besitzt, die sich von seinen Umfang erstrecken. Der Wärmeleitkörper weist von der oberen zu der unteren Seite des Kühlkörpers ein Durchgangsloch auf, ferner sind eine obere Platte und eine untere Platte vorgesehen, die die Öffnungen des Durchgangslochs abdichten, wodurch eine hohle Kammer gebildet wird. Die Kammer ist mit einer Kühlflüssigkeit befüllt, in der ferner eine Umrührvorrichtung angeordnet ist. Die Um rührvorrichtung und ein Rotor eines Kühlungslüfters sind so angeordnet, dass die magnetischen Komponenten eine gegenseitige magnetische Anziehung ausüben, wodurch die Umrührvorrichtung von dem Rotor mitgezogen wird und sich daher synchron mit diesem dreht.Of the Heat sink according to the invention comprises a central heat conduction body, the several cooling fins possesses that extend from its circumference. The heat-conducting body has from the upper to the lower side of the heat sink, a through hole, Furthermore, an upper plate and a lower plate are provided, the openings of the through-hole, thereby forming a hollow chamber becomes. The chamber is filled with a coolant filled, in the further a stirring device is arranged. The order stirring device and a rotor of a cooling fan arranged so that the magnetic components are mutual to exercise magnetic attraction, whereby the stirring device is dragged by the rotor and therefore synchronously with this rotates.
Die untere Platte, die aus einem Werkstoff mit höherem Wärmeleitungskoeffizienten als jenem des Kühlkörpers besteht, kann ausgetauscht werden. Somit kann die Wärme des wärmeerzeugenden Elements schnell absorbiert und im Wesentlichen sofort zur Kühlflüssigkeit geleitet werden.The lower plate made of a material with higher coefficient of thermal conductivity than that of the heat sink, can be exchanged. Thus, the heat of the heat-generating element can be fast absorbed and passed substantially immediately to the cooling liquid.
Weiterhin weist die der Kammer zugewandten Seite der unteren Platte mehrere Hilfskühlrippen auf.Farther has the chamber facing side of the lower plate more Auxiliary cooling ribs on.
In Verbindung mit dem Kühlrippenentwurf können diese Kühlrippen dann, wenn die Umrührvorrichtung die Kühlflüssigkeit umrührt, den Kontaktbereich der Kühlrippen mit der Kühlflüssigkeit erhöhen, andererseits kann eine Mischungswirkung der turbulenten Strömung der Kühlflüssigkeit erhöht werden, so dass die absorbierte Wärme schnell und gleichmäßig diffundieren kann, was eine effiziente Wärmeabführwirkung gewährleistet.In conjunction with the cooling fin design For example, these cooling fins may increase the contact area of the cooling fins with the cooling liquid when the agitating device stirs the cooling liquid, on the other hand, a mixing effect of the turbulent flow of the cooling liquid may be increased so that the absorbed heat can diffuse quickly and uniformly, ensuring an efficient heat dissipation effect.
Weitere Merkmale und Vorteile der Erfindung werden deutlich beim Lesen der folgenden Beschreibung, die auf die Zeichnungen Bezug nimmt; es zeigen:Further Features and advantages of the invention will become apparent upon reading the following description referring to the drawings; it demonstrate:
Die Erfindung betrifft eine Kühlkörper-Struktur, bei der der mittige Wärmeleitungskörper des Kühlkörpers Durchgangslöcher aufweist, die von zwei Seiten eindringen, wobei die Öffnungen auf beiden Seiten mit einer oberen Platte bzw. mit einer unteren Platte abgedeckt sind, um eine vollständig abgedichtete hohle Kammer zu bilden. Die untere Platte ist aus einem Werkstoff mit höherem Wärmeleitungskoeffizienten hergestellt, so dass die durch das wärmeerzeugende Element erzeugte Wärme schnell absorbiert wird, um die Wärmeabführung des Kühlungslüfters zu erleichtern. Weiterhin weist die der Kammer zugewandte Seite der unteren Platte mehrere Hilfskühlrippen auf.The Invention relates to a heat sink structure, in which the central heat conduction body of the heat sink has through holes, which penetrate from two sides, with the openings on both sides covered with an upper plate or with a lower plate are to complete one sealed hollow chamber to form. The lower plate is made of one Material with higher Heat transfer coefficient made so that the heat generated by the heat generating element Heat quickly is absorbed to the heat dissipation of the Cooling fan to facilitate. Furthermore, the chamber facing side of the lower plate several auxiliary cooling ribs on.

Daher sind die resultierenden turbulenten Strömungen alle unterschiedlich, so dass in der Kammer eine stärker turbulente Strömung erzeugt wird.If also the auxiliary cooling ribs different heights own, meets the coolant at different heights on the auxiliary cooling ribs. Therefore, the resulting turbulent flows are all different, so that in the chamber a more turbulent flow is produced.

Zusammengefasst besitzt der Kühlkörper mit dem erfindungsgemäßen Entwurf eine untere Platte mit einem höheren Wärmeleitungskoeffizienten als der Kühlkörper, wodurch die Wärmeübertragungsgeschwindigkeit erhöht wird, die Wärmediffusion verbessert wird und die durch das wärmeerzeugende Element erzeugte Wärme schnell abgeführt wird. Diese untere Platte ist austauschbar. Diese Struktur ist mit dem Entwurf von Hilfskühlrippen kombiniert. Somit wird einerseits die Kontaktfläche mit der Kühlflüssigkeit erhöht, andererseits wird die Mischungswirkung aufgrund stärker turbulenter Strömungen erhöht, so dass die durch die Kühlflüssigkeit absorbierte Wärme schneller und gleichmäßiger an die einzelnen Kühlrippen übertragen werden kann.Summarized has the heat sink with the inventive design a lower plate with a higher one Heat transfer coefficient as the heat sink, causing the heat transfer rate elevated will, the heat diffusion is improved and generated by the heat generating element Heat quickly dissipated becomes. This lower plate is interchangeable. This structure is with the design of auxiliary cooling ribs combined. Thus, on the one hand, the contact surface with the cooling liquid elevated, On the other hand, the mixing effect is due to more turbulent currents elevated, so that through the coolant absorbed heat faster and smoother transfer the individual cooling fins can be.
