Micro heat pipe module for AR smart glasses

Augmented Reality smart glasses are equipped with a powerful processor in the center unit.
This processor creates a lot of heat which needs to be cooled in an efficient way.
Applications running on AR glasses are requiring more and more calculation power.

Challenge:

• Cooling solution in smallest possible size
• 5 to 10 watts of heat on a local spot
• Light weight for overall minimal weight increase
• Passive heat transfer to avoid extra power losses

Solution:

• Ultra compact heat pipe design on custom developed mechanics
• Two D3 heat pipes spread and transport the heat away from the core
• Heat pipes work without impact of direction and gravity
