Description
Technisches Gebiet Technical area
Die Erfindung betrifft eine Kühlstruktur für tragbares Gerät, die die Kühlwirkung für die elektronischen Bauelemente im tragbaren Gerät erhöhen kann. The invention relates to a portable device cooling structure which can increase the cooling effect of the electronic components in the portable device.
Stand der Technik State of the art
Die Betriebswärme der Mobilgeräte (wie dünnes Notebook, Tablet-PC, Smartphone usw.) steigt mit der Erhöhung der Rechengeschwindigkeit. Um die Tragbarkeit zu erhöhen, sind die Mobilgeräte immer dünner. Um einen Eintritt von Fremdstoffen und Feuchtigkeit zu verhindern, sind die Mobilgeräte abgesehen von dem Audioanschluss und Ladeanschluss geschlossen ausgebildet. Dadurch ist eine Konvektion mit der Außenluft schwer. Die Wärme der Recheneinheit und der elektronischen Bauelemente kann nicht schnell abgeleitet werden und wird somit im Mobilgerät gesammelt, so dass die Arbeitsleistung des Mobilgeräts beeinflusst wird. The heat of operation of mobile devices (such as thin notebook, tablet PC, smartphone, etc.) increases with the increase in computing speed. To increase portability, mobile devices are becoming thinner and thinner. To prevent ingress of contaminants and moisture, the mobile devices are closed except for the audio port and charging port. This makes convection with the outside air difficult. The heat of the arithmetic unit and the electronic components can not be dissipated quickly and is thus collected in the mobile device, so that the work of the mobile device is affected.
Um das obengenannte Problem zu lösen, wird im Mobilgerät ein passives Kühlelement, wie Wärmerohr, Vapor-Chamber, Kühlkörper usw., eingebaut. Wegen der kleinen Dicke ist der Aufnahmeraum im Mobilgerät begrenzt, wodurch die Dicke des Kühlelements auch verkleinert werden muss. Wenn die Dicke des Wärmerohrs oder des Vapor-Chamer-Kühlers zu klein ist, wird die Anordnung der Kapillarstruktur und des Dampfkanals im Mobilgerät begrenzt, so dass die Wärmeleitwirkung des Wärmerohrs oder des Vapor-Chamer-Kühlers reduziert wird. Wenn die Rechengeschwindigkeit der Recheneinheit zu hoch ist, können Wärmerohr, Vapor-Chamber oder Kühlkörper alle die Wärme nicht wirksam ableiten. To solve the above problem, a passive cooling element such as heat pipe, vapor chamber, heat sink, etc. is installed in the mobile device. Because of the small thickness of the receiving space is limited in the mobile device, whereby the thickness of the cooling element must also be reduced. If the thickness of the heat pipe or vapor chiller cooler is too small, the capillary structure and steam channel placement in the mobile device is limited, thereby reducing the thermal conductivity of the heat pipe or the vapor chamer cooler. If the processing speed of the processing unit is too high, the heat pipe, vapor chamber or heat sink can not effectively dissipate the heat.
Der Aufnahmeraum des tragbaren Geräts ist eng und die elektronischen Bauelemente sind dicht im Aufnahmeraum angeordnet, wodurch die Wärme leicht im Aufnahmeraum gesammelt werden kann. The receptacle of the portable device is narrow and the electronic components are arranged close to the receiving space, whereby the heat can be easily collected in the receiving space.
Aufgabe der Erfindung Object of the invention
Der Erfindung liegt die Aufgabe zugrunde, eine Kühlstruktur für tragbares Gerät zu schaffen, die die obengenannten Nachteile der herkömmlichen Lösung beseitigen kann. The invention has for its object to provide a cooling structure for portable device, which can eliminate the above-mentioned disadvantages of the conventional solution.
Diese Aufgabe wird durch die erfindungsgemäße Kühlstruktur gelöst, die einen Träger umfasst, der einen Aufnahmeraum aufweist, in dem eine Schaltungsplatte aufgenommen wird, wobei auf der Schaltungsplatte mindestens ein elektronisches Bauelement angeordnet ist, wobei an einer Seite des elektronischen Bauelements mindestens eine Wärmeleitschicht angeordnet ist, wobei auf der dem elektrischen Bauelement gegenüberliegenden Seite der Wärmeleitschicht eine Graphitschicht angeordnet ist. This object is achieved by the cooling structure according to the invention, which comprises a carrier which has a receiving space in which a circuit board is accommodated, wherein at least one electronic component is arranged on the circuit board, wherein at least one heat conducting layer is arranged on one side of the electronic component, wherein on the opposite side of the electrical component of the heat conducting layer is arranged a graphite layer.
