Zipper Heat Sink Manufacturers & Suppliers

High-Precision Customization
Supported by a 25-member R&D team and 20-member mold/design team, combined with multi-dimensional simulation capabilities (e.g., ±0.5°C precision validation in server heat sink cases), we deliver rapid customized solutions from topology optimization to structural adaptation.

End-to-End In-House Production
Full control over stamping, CNC machining, welding, and other key processes. The stamping workshop includes 12 presses (3 high-speed) for 400K/M capacity, while 42 CNC vertical machines ensure complex fin forming with ±0.01mm precision.

Quality & Performance Assurance
ISO9001/QC080000 certified, 40+ quality inspectors, and advanced testing (wind tunnel, salt spray) guarantee thermal efficiency and durability for high-reliability applications like servers and automotive systems.

What is a Zipper Fin Heat Sink?

A Zipper Fin Heat Sink features densely interlocked fins formed via high-precision stamping or folding, offering:

Structural Superiority: Interleaved “zipper-like” fin arrangement maximizes surface area and airflow efficiency.
Material Flexibility: Compatible with copper, aluminum, and composites, integrated with heat pipe sintering tech (1.8M/M capacity).
Performance Leap: 30% lower thermal resistance vs. traditional extruded aluminum heat sinks, ideal for high-power-density scenarios.

Zipper Fin Heat Sink Production Capacity

Process	Equipment	Monthly Capacity	Precision
Stamping	12 presses (3 high-speed)	400,000 PCS	±0.05mm (mold-level)
CNC Machining	42 vertical CNC machines	650,000 PCS	±0.01mm (3D measurement)
Heat Pipe Integration	3 sintering furnaces + 2 auto-powder fillers	1,800,000 pipes	K-value ±5% (wind tunnel)
Assembly & Testing	4 assembly lines + 5 thermal testers	1,220,000 PCS	Temp. fluctuation ≤1°C

Key Benefits & Value

Unmatched Thermal Performance
- Case validation: Optimized fins achieve ≤2.3°C base temperature difference in 300W server scenarios (IGBT control box simulation).
- Lightweight design: 90%+ aluminum, 40% lighter than copper-based solutions.
Versatile Application Coverage
- Power range: 10W–600W, compatible with hybrid air-cooled/liquid-cooled systems (e.g., vacuum-brazed liquid cold plates).
- Miniaturization: 0.8mm minimum fin spacing for compact spaces (e.g., laser projectors).
Cost & Delivery Excellence
- Economies of scale: In-house stamping/CNC reduces unit cost by 15% vs. outsourcing.
- Rapid prototyping: Samples delivered in 72 hours post-design.
