Description
Technical field
The present invention relates to a kind of laptop radiating docking station, particularly a kind ofly carry out direct hot linked laptop radiating docking station by small-sized heat pipe in heat pipe array and the notebook computer.
Background technology
The mobile processor of notebook computer possesses the function of working usually under multi-frequency: when using battery, mobile processor is operated in low-limit frequency (being generally 800MHz) with saves energy; When using external power adapter, mobile processor is operated under the normal frequency; And when notebook computer is processed the computation-intensive task, mobile processor again can automatic lifting high operate frequency (Intel and AMD all have this type of technology, and Intel is referred to as Turbo Boost, farsighted frequency) to improve calculated performance.The principle of work of farsighted frequency technology please refer to Intel correlation technique document, does not describe in detail herein.Farsighted frequency time length mainly is subject to processing the restriction of device red line temperature, and when processor works long hours when farsighted frequency state causes excess Temperature, frequency of operation can reduce with cooling automatically, causes farsighted frequency failure.
The trend of polarization appears in the at present development of notebook computer.Occur on the one hand super and waited the fuselage thickness ultrathin, the light type of battery endurance overlength, the Mac Book Air of American apple company for example, fuselage thickness is 3mm-17mm, battery endurance reaches 7 hours (equipment Intel Ivy Bridge processor) or 11 hours (equipment Intel Haswell processor), the Thinkpad X1 Carbon of Chinese Legend Company for example again, fuselage thickness is 8mm-18mm, battery endurance reaches 6 hours (equipment IntelIvy Bridge processor), is equipped with the double-core extra low voltage more and moves integrated graphics card in processor (TDP is 15 watts-17 watts usually) and the processor; Powerful mobile workstation (Mobile Workstation) and the game-specific notebook of calculated performance appearred on the other hand, characteristics are bulky, can hold large-scale heating radiator and a plurality of radiator fan, therefore (TDP is 45 watts-55 watts usually often to be equipped with the mobile processor of high performance four nuclears, Intel Extreme Edition (Extreme Edition) processor TDP can release to as high as more than 105 watts) and display card, the former is the Thinkpad W series of Legend Company for example, the Elitebook series of hewlette-packard, the M series of Dell company, the latter is the Alienware series of Dell company for example.And the lightweight notebook computer is subjected to the restriction of body volume and weight, and the huge heat that gives out in the time of can't adopting large-scale heating radiator and a plurality of fan to the mobile processor full speed operation of high-performance four nuclears is controlled.In addition, even the very little mobile workstation (Mobile Workstation) of the 17-18 of most significant end and game-specific notebook, type is joined on its top that is equipped with Intel Extreme Edition processor still can't suppress Extreme Edition processor release TDP overclocking heat afterwards for a long time.For example 17 cun mobile workstations of Thinkpad W701 of Legend Company are equipped Intel I7 920XM Extreme Edition processor, default frequency 2.0GHz, the farsighted frequency 3.2GHz of monokaryon, the farsighted frequency 2.16GHz of four nuclears, standard TDP55 watt, Cinebench R11.5 testing software score 3.45; Can reach 105 watts after the release TDP, the farsighted frequency 3.46GHz of monokaryon, the farsighted frequency 3.33GHz of four nuclears, Cinebench R11.5 testing software score should reach about 5.5 in theory, and performance improves 50%.Although the dual-fan system of Thinkpad W701 can be well the temperature of the I7920XM of default frequency is controlled at about 80 degree, but the temperature of the I7920XM after the uncontrollable release overclocking, the result is that the temperature of fully loaded processor can reach 105 degree red lines gradually, cause mobile drop processor frequency dispersion heat, performance reduces greatly.If notebook computer can be equipped enough large-scale heating radiator and a plurality of fan, the temperature that is fully loaded with processor is controlled at below the red line frequency reducing temperature, just can be operated under the high-frequency high-performance state by long-time farsighted frequency, give full play to performance.But because the notebook computer finite volume can't be equipped enough large-scale heating radiator and a plurality of fan, can only equip a small heat-dissipating device and 1-2 fan.
Therefore the present invention proposes a kind of laptop radiating docking station, enough large-scale heating radiator and a plurality of fan are placed the laptop radiating docking station.In the laptop radiating docking station large-scale heat-pipe radiator and notebook computer in mobile processor on original low profile thermal tube radiator directly link to each other by special purpose interface, greatly improved heat transfer efficiency.And notebook radiator is in the market generally lowered the temperature for shell and the air outlet of notebook computer, and radiating efficiency is extremely low.When notebook computer be in mobile in, small heat-dissipating device and fan in the notebook computer can be controlled the mobile processor that is operated under the lower frequency fully.When notebook computer links to each other with the laptop radiating docking station, enough large-scale heating radiator and a plurality of fans in the laptop radiating docking station can be controlled at the temperature that is fully loaded with processor below the red line frequency reducing temperature, processor just can be operated under the high-frequency high-performance state by long-time farsighted frequency, gives full play to performance.Simultaneously notebook computer itself can keep the small and exquisite and strong advantage of endurance of volume.The laptop radiating docking station also can link to each other with mobile workstation or game-specific notebook in addition, both cooling systems can associated working with control high-performance mobile processor, Intel Extreme Edition processor particularly, temperature during fully loaded work is given full play to the advantage of its farsighted frequency and overclocking.
