Abstract
Vorrichtung zum Wärmeabfuhr eines elektronischen Bauteils, die aus einem keramischen Material besteht und die auf ihrer Oberseite (212) eine durch Luftkanäle gebildete Strukturierung (22) aufweist und auf ihrer Unterseite (211) mit dem elektronischen Bauteil in Kontakt steht, dadurch gekennzeichnet, daß die Strukturierung aus eine Vielzahl von in parallelen Reihen hintereinander bestandet angeordneten Erhebungen (22) besteht, und daß in der unterhalb der Strukturierung (22) liegenden Grundplatte (21) eine Anzahl von Kühlrohren (23) für eine Kühlflüssigkeit eingebettet sind.contraption for heat dissipation an electronic component made of a ceramic material and which on its upper side (212) is formed by air ducts Structuring (22) and on its underside (211) with the electronic component is in contact, characterized that the Structuring of a plurality of in parallel rows one behind the other exists arranged elevations (22), and that in the below the structuring (22) lying base plate (21) a Number of cooling pipes (23) for a cooling liquid are embedded.
Description
[Technisches Gebiet][Technical area]
Die Erfindung betrifft eine Vorrichtung zur Wärmeabfuhr eines Chips nach dem Oberbegriff des Anspruchs 1.The The invention relates to a device for heat removal of a chip the preamble of claim 1.
[Stand der Technik][State of the art]
Zur

seines Betriebs erzeugt wird, setzt man eine Wärmeabfuhr-Vorrichtung
Nachteilig
ist bein der bekannten Vorrichtung, daß die Luft in den durch die
Kühlrippen
Hier will die Erfindung Abhilfe schaffen. Der Erfindung liegt die Aiufgabe zugrunde, eine Vorrichtung zum Wärmeabfuhr eines Chips bereitzustellen, mit der die vorbeschriebenen Nachteile vermieden werden.Here The invention aims to remedy this. The invention is the Aiufgabe underlying, a device for heat dissipation of a chip with which the above-described disadvantages be avoided.
Damit die Strukturierung über eine größere Oberfläche mit der Kühlluft kontaktieren kann und die dadurch gebildeten Luftkanäle miteinander komunizieren können, ist die Strukturierung durch Erhebungen gebildet, die in parallelen Reihen beabstandet hintereinander angeordnet sind, wodurch zwischen den Erhebungen kreuzenden Längs- und Querluftkanäle gebildet sind. Darüber hinaus sind in der Grundplatte Flüssigkeitskanäle für eine Kühlflussigkeit eingebohrt, über die eine Kühlflüssigkeit geleitet wird. Auf diese Weise erhält ein Chip eine zweifache Kühlung, sowohl durch Luft als auch durch eine Kühlflüssigkeit. Infolgedessen wird die Wirksamkeit der Kühlung erheblich erhöht.In order to the structuring over a larger surface with the cooling air can contact and communicate with each other the air ducts formed thereby can, the structuring is formed by surveys that are parallel Rows spaced apart are arranged one behind the other, whereby between the Elevations crossing longitudinal and transverse air channels are formed. About that In addition, in the base plate, liquid channels for a cooling liquid drilled, over the one cooling liquid is directed. In this way, a chip gets a double Cooling, both by air and by a coolant. As a result, will the effectiveness of cooling significantly increased.
Die Erfindung wird nachfolgend anhand von in der Zeichnung dargestellten Ausführungsformen näher erläutert. Es zeigen:The Invention will now be described with reference to the drawing Embodiments explained in more detail. It demonstrate:
