Description
Technical field
The present invention relates to mobile phone heat abstractor, particularly relate to a kind of mobile phone heat abstractor with external cooling air channel.
Background technology
Nowadays one of communication tool that mobile phone is indispensable in having become people's life, along with the increase of cell-phone function, the caloric value of mobile phone is more and more higher in use；When mobile phone is overheated, the power consumption of mobile phone can increase accordingly, causes the cell phone standby time to shorten；When mobile phone temp is too high, possibly even there are the phenomenons such as deadlock in mobile phone, the potential safety hazards such as blast the most easily occurs simultaneously；Particularly when summer, the use of short time will make mobile phone hot, the service life of this serious curtailment mobile phone；In addition; people also like mobile phone is used containment vessel; mobile phone shell is prevented from abrasion when mobile phone falls by mistake; but but have a strong impact on the heat radiation of mobile phone; the poor mobile phone shell of some materials under the high-temperature baking of mobile phone it also occur that deformation; not only do not have protective effect, also can make that mobile phone is overheated, the lost of life.
Along with the continuous upgrading of mobile phone hardware, the chip parts such as its performed task computation processes more numerous and diverse, CPU will face the invasion and attack of heat.CPU core calculation improves constantly, and dominant frequency is more and more higher, so that mobile phone is properly functioning, it is particularly important that the good heat radiating of mobile phone becomes.Mobile phone volume has certain limitation, and processor system performance can decrease because temperature raises, and therefore the power limit of mobile phone is not to be exceeded its heat-sinking capability.
The heat radiation of actual mobile phone is still divided into actively dispels the heat two kinds with passive, and basic thinking is to reduce the thermal resistance of mobile phone heat radiation or reduce the caloric value of mobile phone, and the former is passive heat radiation, and the latter is active heat removal category.Active heat removal reduces heat by the power consumption reducing chip and realizes, and present mobile phone main flow has several heat sink conception:
One, graphite radiating scheme:
Conductive graphite sheet (GTS) is also referred to as graphite heat radiation fin, it is a kind of brand-new heat conduction and heat radiation material, there is the crystal grain orientation of uniqueness, along both direction uniform heat conduction, laminar structured being well adapted for, improves the performance of consumer electronics product at any surface while shielding thermal source and assembly.Why can be designed to graphite heat radiation fin, also use the plasticity of graphite, we can make graphite material the thin slice of one piece of picture paster, allows it be attached to the circuit board top of interior of mobile phone.Both can intercept the contact between original paper, also function to certain antihunt action.
Pyrotoxin CPU and Flash chip caloric value are big, and graphite heat radiation fin is on the encapsulated layer of these chips, and the another side of fin can be attached to above the metallic plate of centre in fuselage.The another side of metallic plate the most also has one piece of graphite heat radiation fin, corresponding connection cell phone back cover.After screen and the heat of CPU/Flash all mutually can be transmitted by middle metal level, due to the heat-sinking capability that graphite heat radiation fin is more outstanding, plus outstanding thickness and plasticity, dispel the heat after finally making heat to be uniformly distributed and by the flowing of air, also can survive inside narrow and small mobile phone space.
Two: ice nest dispels the heat
The heat radiation of ice nest is to improve in basic graphite radiating scheme, uses the ice nest cooling system with exclusive patent.This system is to add the metal material of a kind of fluid-like state between chip and graphite, is solid-state usually, treats that, the when that chip heating strengthening, it will absorb heat and become liquid, improves heat transference efficiency.
But being as the development of mobile phone technique, people increasingly pursue the Novel mobile phone that performance is gradually climbed to a higher point, for overwhelming majority crowd, its high performance nature often can't be used.But popular along with the mobile phone games of high demand, testing mobile phone software etc., for the high performance demands in the mobile phone short time, and the short time high heat problem brought therewith, high degree have impact on mobile phone and uses and the life-span.
Summary of the invention
It is an object of the invention to solve the problem in above-mentioned background technology; a kind of mobile phone heat abstractor with external cooling air channel is provided; make full use of external interface and the protection shell of the common accessory of mobile phone of mobile phone, mobile phone inner heat chip particularly cpu chip is provided the radiating mode of a kind of new way.
For realizing the object of the invention, the technical scheme of employing is:
A kind of mobile phone heat abstractor with external cooling air channel, including interior of mobile phone euthermic chip, mother's USB mouth and outside mobile phone shell, it is characterized in that: be connected between the euthermic chip of interior of mobile phone with mother's USB mouth and have banding heat transfer piece, described banding heat transfer piece have certain insulating properties or and mother's USB mouth between be provided with insulating barrier；Described outside mobile phone shell is provided with the USB public affairs mouth matched with mobile phone, the air channel of certain distance is left between outside mobile phone shell and mobile phone backboard, and in air channel, it is provided with electronic radiator fan, and it is provided with flat radiating tube in outside mobile phone shell, the metal of the USB public affairs mouth in outside mobile phone shell connects shell and is connected with radiating tube heat transfer, and the power line of USB public affairs mouth is connected with electronic radiator fan.
Further, described banding heat transfer piece is metal material, is provided with insulating sticky sticks layer with the euthermic chip of interior of mobile phone and the junction of mother's USB mouth.
Further, described banding heat transfer piece is copper or aluminium material.
Further, described banding heat transfer piece is arranged on the metal connection shell of mother's USB mouth.
The present invention is at interior of mobile phone euthermic chip such as CPU etc., the amount of heat that it is given out when high-performance is run, transfer heat in the outside mobile phone shell of the Cellphone Accessories with radiating tube by the USB interface of mobile phone, dispelled the heat by the air channel in mobile phone shell and radiating tube, to tackle the mobile phone high radiating requirements in the short time.
The new way radiating mode provided by the present invention; make full use of by mobile phone USB interface metal is connected shell; provide and a kind of both met user's demand for Cellphone Accessories containment vessel, the advantage that impact of mobile phone will not being dispelled the heat again, it is integrally improved the heat dispersion of mobile phone simultaneously.
