 Advanced Technology

01.  Chip Protector: Highly efficient heat transfer core 

Core Technology Of Heat Sink—— Heat Column

• Invention Patent in China: ZL 2010 1 0162168.4
  

• Phase Change Heat Transfer Principle
  

• Thermal conductivity of Heat column is several hundred times more than any materials.
  

• Start to function while the temperature is below 28℃
  

• Performance is stable, small cyclical fluctuations
  

• Automated production to ensure product consistency
  

02.Nano-coating technology to accelerate heat dissipation 

Nano-coating appearance enhances heat dissipation,better for corrosion

03.Chimney effect convection enhance tyhe performance
