The Principle Of TCGS In XiaoMi Mobile Phone

                                                  One Case Of Graphite Material Applications 

1、What's Graphite?

Graphite is the allotropes of the carbon,by covalent bond each carbon atom is surrounding link with the other three carbon atoms (in multiple hexagonal honeycomb to arrange),to be covalent molecules.because each carbon atom will emit an electron, the electrons can move freely,so graphite belongs to the conductive body.graphite can be refractory material.graphite can be conducting material.graphite can be wear-resistant and self-lubrication material.because of chemical stability,graphite can be made in heat exchanger,reactive tank,condenser,combustion tower,absorption tower,cooling unit,heating element.graphite can save much material if used in petrochemical industry,hydrometallurgy,Acid and alkali production etc.The graphite is used as part of the cell phone design,we can see a lot of useful things.For example,Thermal Conductivity Of Graphite Sheet(TCGS) is used in the current mobile phone which mainly is the use of the thermal conductivity of the graphite.

2、What's TCGS?

TCGS,Thermal Conductivity Of Graphite Sheet.

it Is a kind of new thermal heat and dissipation material,it has the unique grain orientation,along the two directions it has same thermal conductivity,the layered structure of the tablets can be well adapted to any surface,to improve the performance of consumer electronics when it is shielding the heat source and components at the same time.

because of the plasticity of graphite, we are able to design into TCGS.we can make graphite material to like a sticker sheet,and make it stick attached to the inside of the mobile phone circuit board.it can also cut off the materials contacts,but also it plays a role of anti-seismic effect.

3、Introduce The Heat Dissipation Principle Of XiaoMi Mobile Phone

In the conference of XiaoMi mobile phone,lei jun was solemnly declared to the cooling characteristic of the XiaoMi mobile phone,through it is not the first time that the TCGS used  in the mobile phone,but it is rare to promote as a advantage.

Here we try to introduce it simply:

one of the hot source in XiaoMi mobile phone is CPU and Flash chip,therefore on these chips encapsulation layer,it has a "7" type of TCGS,the other side of the radiator is inside of metal plate in the middle of the above.While another larger piece of TCGS is in the middle of the metal plate on the other side in XiaoMi mobile phone,it connects the back of the screen.

So,when the phone don't be open, we can see the back of the screen and CPU/Flash heat can pass through the middle of the metal layer,it eventually makes heat uniformly,and fianlly it's for cooling through the flow of air.So,we can say that part of the heat will go through the LCD side auxiliary cooling,in addition,the back cover of mobile phone can also be cooled.

Therefore,we can say, XiaoMi mobile phone of TCGS is actually playes the role of the heat conduction,and the even distribution of heat,indirectly, that is the cooling effect.
