Passive heat pipe heat spreader for slim PC

The demand for slim and passive laptop computer requires a thin and passive thermal solution to avoid fan and air flow noise. Well routed flattened heat pipes and thin plate assembly is the  solution to spread heat flux efficiently and optimize users’ experience.

Challenge:

• Passive cooling solution in slimmest possible size
• 10~30 watts of dynamic heat flux from microprocessors
• Light weight for overall minimal weight increase
• Good passive heat spreading performance

Solution:

• Well routed flattened heat pipe(s) and thin plate assembly
• 3 x spring plates around heat source for sufficient contact force
