Heat pipe heat sink with zipper fin 

Heat pipes are capable of quickly increasing the application area of self cooling. Since a heat pipe self-cooling system does not need any fan, it generates no noise and it doesn’t require maintenance so it’s safe and reliable. Heat pipe air cooling or self cooling can even replace water cooling systems so as to reserve water resources and the investment on relevant auxiliary equipment. Moreover, the heat pipe cooling approach allows the heat-dissipating devices to be concentrated and even sealed. This allows the cooling parts to be relocated to the exterior or in the distance so as to enhance the safety, reliability, and application range of electronic equipment and realize the dust-proof, damp-proof, and explosion-proof requirements.

The fins are welded, made of stamping material aluminum or copper, and folded into a shape with interlocking slots.The folding fin can transfer high thermal energy and has more than 3000 different configurations. Larger surface area, more flexible design and more stable structure than extruded fins, allowing very high fin density and length-width ratio, thus increasing surface area and better cooling. Zipper fins also increase design flexibility, especially for pipes that integrate heat pipes, fans, or blowers.
