Nowadays, the tablet computer will be felt hot and scorching after playing games for more than half an hour. You may think that the manufacturer has not done a good job in heat dissipation.

In fact, it is not. It is the horizontal and efficient heat conduction of the heat source computer chip through the graphite heat dissipation film, which diffuses the heat source temperature. This avoids the local high temperature of the computer caused by the high temperature generated by the fast operation of the tablet computer chip, resulting in the deformation of the circuit board or the computer crash.

I believe that you have a certain understanding of the thermal conductive graphite sheet for tablet computers. Then, how the tablet computer dissipates heat through the thermal conductive graphite sheet?

 

 

Tablet PC has a main chip and two small chips. The main IC causes a lot of heat. 

Underneath the IC, there is also a graphite sheet for thermal conductivity, which allows heat to be quickly diffused through the circuit board on the back of the IC and conducted to the tablet's housing.

 

Heat dissipation is achieved through the large contact area of the housing with the air.

Not only the tablet PC circuit board behind the pad with thermal conductive graphite sheet, the top of the tablet PC chip is also attached the thermal conductive graphite sheet. 

Graphite sheet close to the chip and metal frame on the back of the display, through the display to achieve the purpose of screen heat dissipation.

 

 After reading this article, I believe that you have probably understood why the tablet computer will heat up after using it for a long time.

Because of the high thermal conductivity, graphite sheet will conduct heat from the tablet's heat source to the case and display. 

Through a large contact area with air to achieve the purpose of heat dissipation, to ensure the normal operation of the tablet computer chip,  greatly extending the life of the tablet computer and the performance of use.
