Summary:

 

Graphite thermal heat sink is an entirely new cooling material, heat conduction along two direction, shielding heat source and even a while to improve the performance of consumer electronic products.

 

Product features:

 

• · thermal conductivity far beyond copper, aluminum, thermal resistance, a 40 per cent lower than aluminum 20% lower than copper

• · lighter weight, density than aluminum light 28%, general than copper light 78%

• · expanded the current fan/cooling technology new beginning.

Main application: graphite fin can smooth stick add in any plane and curved surface, and can according to the requirements of customers do any form of cutting, mainly used in notebook computers, flat panel display. Digital cameras, mobile phones and the main equipment and for individuals can be applied to electric power, petroleum, chemical industry, instrumentation, machinery and other industries machine, tubes, pumps, valves, dynamic seals and sealing is to replace rubber, fluorine plastic, asbestos such traditional seals of the ideal new type sealing material.

 

 

 

Application field

 

 

 

Electronic industry is a high and new technology is the main product is market of graphite. The high-tech production improved graphite used in electronic products cooling system can make the electronic product rapid heat dissipation, such as LCD computer, ultra pure graphite used in lithium ion batteries and alkaline electrode can improve conductivity, ultra pure expanded graphite foil for fuel cell electric plate can improve conductivity reduce weight.
