Portable computer device
Technical field
The present invention relates to a kind of portable computer device, espespecially a kind of thermal isolation film that uses is to completely cut off or to reflect heat generating component and be passed to the portable computer device of the heat energy on crust of the device.
Background technology
Along with the progress of portable electronic science and technology, the function that portable computer device (as notebook computer etc.) can provide becomes increasingly complex and is powerful, this has also represented that its internal electrical components is (as central processing unit simultaneously, hard disk, motherboard etc.) data processing speed must be more and more faster, so that it can deal with huge system job workload, but this heat energy that has also represented that its internal electrical components produces in operation also can constantly upwards rise violently, therefore when heat dissipation problem just becomes dealer and designs portable computer device an important topic must considering.
With regard to notebook computer, due to the heat energy accumulation fast that its internal electrical components produces, therefore the quality of heat dissipation has critical impact really on the general performance of notebook computer.Generally speaking, in notebook computer, need on the electronic package of heat radiation, as central processing unit, hard disk etc., all can reach the effect that the thermal energy transfer that produces when electronic package is operated is discharged to the crust of the device of notebook computer with the combination of fan and heat radiator.But after using after a while, heat energy tends to continue to be accumulated on the crust of the device of notebook computer and forms hot-zone, thereby produces the problem of the crust of the device local surfaces excess Temperature of notebook computer at notebook computer.
Therefore, need to provide a kind of portable computer device to solve the problems referred to above.
Summary of the invention

Embodiment
Refer to Fig. 1, its cut-away section schematic diagram that is the portable computer device 10 that proposes according to one embodiment of the invention, in this embodiment, portable computer device 10 can be preferably a notebook computer, but not limit by this, it also can be other common portable computer devices, as flat computer etc.As shown in Figure 1, portable computer device 10 comprises a crust of the device 12, a computer installation 14 and a thermal isolation film 16.Crust of the device 12 can adopt the common casing design on general portable computer that is applied to, and its dependency structure design is common in prior art, therefore do not repeat them here.Computer installation 14 is arranged in crust of the device 12 and has at least one heat generating component 18(and in Fig. 1, only shows one, but not limit by this), as motherboard, hard disk, motor or its combination etc.
Next, refer to Fig. 1 and Fig. 2, Fig. 2 is the part schematic perspective view of the crust of the device 12 of Fig. 1, from Fig. 1 and Fig. 2, in this embodiment, crust of the device 12 can have a base plate 20, thermal isolation film 16 is to be preferably disposed on an inside surface 19 of the corresponding heat generating component 18 of base plate 20 of crust of the device 12, in more detail, thermal isolation film 16 can preferably be arranged on the position of a heat transfer path P of corresponding heat generating component 18 and be right against heat generating component 18(as shown in Figure 1) to reflect or isolated heat generating component 18 is passed to the heat energy of crust of the device 12, but not limit by this, that is to say, as long as thermal isolation film being arranged on to the design on the inside surface of the corresponding heat generating component of crust of the device, it all can be the present invention and adopts.In addition, thermal isolation film 16 can be made up of high thermal resistance material, for example formed or formed by mylar and Silver20HC coating by mylar and high purity metal coating (as silver, nickel, aluminium, copper etc.) etc., its relevant mechanism of heat insulation explanation and design thereof are common in prior art, therefore do not repeat them here.Should be noted, the heat insulation area of thermal isolation film 16 can be determined according to the hot-zone forming because of the lasting accumulation of heat energy on base plate 20 or the area of focus.
Thus, as shown in Figure 1, after the heat generating component 18 in portable computer device 10 operates a period of time for example, along heat transfer path P transferring heat energy (the heat radiation guide design by the heat abstractor in portable computer device 10 (as the combination of fan and heat radiator etc.) etc.) to the inside surface 19 of the base plate 20 of crust of the device 12 on time, thermal isolation film 16 just can utilization itself insulative properties and reflect or the heat energy that isolated heat generating component 18 transmits, use and prevent that the situation that heat energy continues to be accumulated on the base plate 20 of crust of the device 12 from occurring, so can avoid the generation of local hot spots and reduce the surface temperature of the base plate 20 of crust of the device 12, thereby the problem of the crust of the device local surfaces excess Temperature of mentioned portable computer device in solution prior art.
It is worth mentioning that, as shown in Figure 1, in this embodiment, portable computer device 10 can also comprise a heat conducting film 22, heat conducting film 22 can be preferably by metal material (as copper, aluminium etc.) form and be arranged between thermal isolation film 16 and the base plate 20 of crust of the device 12, by this, in the time that heat generating component 18 transfers heat energy on the inside surface 19 of base plate 20 of crust of the device 12, heat conducting film 22 can utilization itself thermal conduction characteristic can be spread in equably on the inside surface 19 of base plate 20 of crust of the device 12 with the heat energy that makes heat generating component 18 and transmitted, and then performance samming effect.Thus, by the uniform heat conduction design of heat conducting film 22 and the heat energy reflection of above-mentioned thermal isolation film 16 or isolated design, the present invention can further eliminate the heat energy localized accumulated phenomenon producing on the base plate 20 of crust of the device 12.In addition, the configuration of heat conducting film 22 can be not limited to configuration as shown in Figure 1, it also can change employing into and directly be attached at design in thermal isolation film 16 to replace the design between thermal isolation film 16 and base plate 20 that is attached at as shown in Figure 1, as for adopting which kind of configuration, it is depending on the practical application of portable computer device 10.
In sum, compare prior art, the present invention adopts thermal isolation film is arranged to the design on the inside surface of the corresponding heat generating component of crust of the device, transmit its heat energy being produced on the inside surface of crust of the device time with the heat generating component in portable computer device, produce reflection or effect of isolated heat energy by the insulative properties of thermal isolation film, use situation about improving on the crust of the device that heat energy continues to be accumulated in portable computer device.Thus, the present invention can positively avoid the generation of local hot spots and reduce the surface temperature of crust of the device, thereby effectively solves the problem of the crust of the device local surfaces excess Temperature of portable computer device mentioned in prior art.
