Multi heat pipe module for portable projector

Portable projector are equipped with a powerful set of RGB LEDs to project the images.
The light sources generates a lot of heat which needs to be cooled in an efficient way.
Applications for portable projectors are requiring more powerful cooling solutions.

Challenge:

• Cooling solution in smallest possible size
• 10~50 watts of dynamic heat flux from multi LEDs
• Light weight for overall minimal weight increase
• Highest possible active heat exchange efficiency to reduce fans noise

Solution:

• Compact heat pipe module design within custom developed mechanics
• 3x D3 heat pipes transport the heat from multi sources to the fin heat exchange area
• Heat pipes is designed to work best for the orientation
