As a leading manufacturer of custom industrial heat sinks, ZP HEAT SINK specialize in designing and producing high-performance Zipper Fin Heat Sinks tailored to meet the most demanding thermal challenges. Combining advanced thermal simulation, modular design, and robust manufacturing processes, our solutions deliver 30%+ higher cooling efficiency compared to conventional finned heat sinks. Trusted by industries ranging from semiconductor fabrication to 5G infrastructure, we ensure your equipment operates reliably under extreme conditions.
Zipper Fin Heat Sinks feature a multi-layered architecture optimized for maximum heat dissipation
Base Tube
High-conductivity copper/aluminum/stainless steel core for rapid heat absorption.
Dense Folding Fins
Laser-cut, tightly spaced fins (2–4mm pitch) to amplify surface area by 50–70%.
Heat Pipe Integration
Embedded heat pipes or vapor chambers ensure uniform temperature distribution (±1.5°C variance).




Superior Heat Dissipation
Supports 900W–1500W thermal load* (validated via ANSYS CFD simulations).
Space Efficiency
40% smaller footprint than stamped fin designs, ideal for compact enclosures.
Durability
Corrosion-resistant materials (e.g., galvanized steel, copper-aluminum composite) withstand temperatures up to **200°C** and harsh environments (humidity, chemicals).



IGBT modules, motor drives, UPS systems. 5G base stations, RF amplifiers. EV battery cooling, solar inverters, industrial boilers.
Step 1: Thermal Analysis
- Share your requirements: heat load (W), ambient temperature, airflow conditions, space constraints.
- Our engineers perform CFD simulations (using SmartCFD/ANSYS) to optimize fin density, base thickness, and airflow paths.
Step 2: Material & Manufacturing
- Base Materials: Copper (C1100), Aluminum 6063, Stainless Steel 304/316.
- Fin Bonding: Vacuum brazing or ultrasonic welding for zero-gap thermal contact.
- Surface Treatment: Anodizing, nickel plating, or ceramic coating for enhanced durability.
Step 3: Rigorous Testing
- Thermal Resistance Test: Validates heat transfer efficiency (ΔT/W).
- Wind Tunnel Testing: Measures static pressure drop and airflow optimization.
- Environmental Testing: Salt spray (ASTM B117), vibration (MIL-STD-810G)
Advanced Facilities
Extrusion lines, CNC machining centers, Anodizing workshop, Powder coating line etc.


Compliance
ISO 9001:2015, RoHS, CE, UL certification for electrical safety.
Warranty
24-month quality guarantee with traceable batch records.

Q1: How does a Zipper Fin outperform traditional folded fins?
A: Zipper fins' staggered, interlocking design minimizes airflow blockage while maximizing surface area. Combined with heat pipes, they reduce thermal resistance by 15–25% (per ASHRAE benchmarks).
Q2: What's the lead time for custom orders?
A: Standard projects: 7–15 business days. Complex designs (e.g., multi-zone heat sinks): 3–4 weeks (expedited options available).
Q3: Can you handle low-volume prototyping?
A: Yes-we provide 5–10 unit prototype batches with full testing reports.
