Description
Technisches Gebiet Technical area
Die Erfindung betrifft eine Kühlvorrichtung, die die Herstellung erleichtern und die Herstellungskosten reduzieren kann. The invention relates to a cooling device which can facilitate the manufacture and reduce the manufacturing costs.
Stand der Technik State of the art
Die Mobilgeräte (wie Handy, Tablet-PC, PDA) sind mit der Entwicklung der Technologie immer leistungsfähiger und kompakter. Die Bauteile in den Mobilgeräten, wie Zentraleinheit, integrierte Schaltung usw. erzeugen durch den engen Innenraum und die hohe Rechengeschwindigkeit eine hohe Wärme. Um eine normale Arbeit zu gewährleisten, muss diese Wärme rechtzeitig abgeleitet werden. The mobile devices (such as mobile phone, tablet PC, PDA) are becoming more powerful and compact as technology evolves. The components in the mobile devices, such as central processing unit, integrated circuit, etc. generate high heat due to the narrow interior space and the high computing speed. To ensure normal work, this heat must be dissipated in good time.
Das Mobilgerät mit einer Kühlvorrichtung weist üblicherweise ein Gehäuse, einen Rahmen, eine Wärmequelle und einen Wärmeleiter aus Metall oder einem Verbundmaterial auf. Die Wärmequelle (z.B Zentraleinheit, integrierte Schaltung usw.) ist im Gehäuse angeordnet und liegt auf dem Rahmen an. Die Verbindung des Wärmeleiters und des Rahmens kann durch Kleben erfolgen, wobei ein Klebstoff (wie Epoxid) oder ein Klebband den Wärmeleiter an dem Rahmen befestigt. The mobile device with a cooling device usually has a housing, a frame, a heat source and a heat conductor made of metal or a composite material. The heat source (e.g., CPU, integrated circuit, etc.) is located in the housing and rests on the frame. The connection of the heat conductor and the frame can be made by gluing, wherein an adhesive (such as epoxy) or an adhesive tape attaches the heat conductor to the frame.
Die Verbindung des Wärmeleiters und des Rahmens kann auch durch Zinnlöten erfolgen. Beim Zinnlöten wird das metallische Lot geschmolzen, wodurch zwei metallische Bauteile miteinander verbunden werden. Als Lot wird üblicherweise die Zinnlegierung verwendet. Beim Löten werden die metallischen Bauteile nicht geschmolzen. Wenn das Lot geschmolzen wird, werden die beiden metallischen Bauteile durch Diffusion des geschmolzenen Lotes an den Grenzflächen miteinander verbunden. Dadurch lassen sich die gegenseitige Position des Wärmeleiters und des Rahmens leicht verändern. Zudem kann das Lot zwischen dem Wärmeleiter und dem Rahmen zu einer Toleranz der Montage führen. The connection of the heat conductor and the frame can also be done by tin soldering. In tin soldering, the metallic solder is melted, connecting two metallic components together. The solder usually used is the tin alloy. During soldering, the metallic components are not melted. When the solder is melted, the two metallic components are bonded together by diffusion of the molten solder at the interfaces. As a result, the mutual position of the heat conductor and the frame can be easily changed. In addition, the solder between the heat conductor and the frame can lead to a tolerance of assembly.
Aus dem
Aufgabe der Erfindung Object of the invention
Der Erfindung liegt die Aufgabe zugrunde, eine Kühlvorrichtung zu schaffen, die die Montage erleichtert. The invention has for its object to provide a cooling device that facilitates assembly.
Der Erfindung liegt eine weitere Aufgabe zugrunde, eine Kühlvorrichtung zu schaffen, die die Herstellungskosten reduziert. Another object of the invention is to provide a cooling device which reduces manufacturing costs.
Der Erfindung liegt eine nochmals weitere Aufgabe zugrunde, eine Kühlvorrichtung zu schaffen, die bei der Montage eine Toleranz vermeiden kann. The invention is yet another object of the invention to provide a cooling device that can avoid tolerance during assembly.
Diese Aufgaben werden durch die erfindungsgemäße Kühlvorrichtung gelöst, die umfasst: mindestens eine Wärmeleiteinheit, die einen Hohlraum aufweist, in dem mindestens eine Kapillarstruktur und ein Arbeitsfluid angeordnet sind; und mindestens einen Rahmen, der mit der Wärmeleiteinheit verbunden ist, wobei die Wärmeleiteinheit und der Rahmen durch Punktschweißen miteinander verbunden werden, wodurch die Wärmeleiteinheit an dem Rahmen befestigt ist. These objects are achieved by the cooling device according to the invention, comprising: at least one heat conducting unit having a cavity in which at least one capillary structure and a working fluid are arranged; and at least one frame connected to the heat conduction unit, wherein the heat conduction unit and the frame are connected to each other by spot welding, whereby the heat conduction unit is fixed to the frame.
