1. Aluminum fin: stamping process

2. Aluminum base: CNC machining

3. Aluminum fin and base nickel plated, prepare for soldering process

4. Heat pipe manufacturing by heat pipe machine then bended

5. Assembly aluminum fin, aluminum base and heat pipe by soldering process

6. 100% On-line thermal test

7. Inspection, pack and ship.

With heat pipe as the core, Heat sink with heat pipe , which is composed of heat pipe, zipper fin and copper plate,and can solve the heat dissipation problem caused by narrow space or too concentrated heat . The zipper fin, made of stamping material aluminum, and folded into a shape with interlocking slots.The zipper 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.

As a heat sink manufacturer in China, Pioneer Thermal is certified with ISO9001, ISO14001 and TS16949, and has more than 18 years experience in CNC machining, cold forging heatsinks, cold plate heatsinks, die casting heatsinks, extrusion heatsinks, heatpipe assemblies, skived fin heatsinks, stacked fin heatsinks, folded fin heatsinks etc., Pioneer Thermal has own R&D team who can design and run simulation for you if you require design service, or assist your design team to improve the part feasibility from the manufacture point of view (design refine/process optimize/cost reasonable). If you need any heat sink service, please contact Pioneer Thermal.
