The Principle Of TCGS In XiaoMi Mobile Phone

1
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
3
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. Article Sorted By XRD Graphite
