Pin Fin Extruded Heatsinks / Thermal Solutions
Cooling Source pin fin extruded heatsinks are engineered to provide efficient, omnidirectional heat dissipation in compact electronic assemblies where airflow direction is variable or limited. Manufactured using precision aluminum extrusion and finished with black anodizing, these heatsinks deliver consistent thermal performance, mechanical durability, and scalable production readiness.
The CS946 Series offers off-the-shelf pin fin solutions designed for simplified integration, including thermal tape attachment to eliminate PCB drilling while maintaining reliable thermal interfaces.
Key Benefits & Features
- Omnidirectional airflow efficiency
Pin fin geometry enables uniform heat dissipation independent of airflow direction, ideal for natural convection or low-velocity forced airflow environments. - Low pressure drop design
Optimized pin spacing balances surface area and airflow resistance for efficient heat transfer. - Broad package compatibility
Suitable for semiconductor packages housed in plastic, metal, or ceramic materials. - Multiple fin height options
Standard fin heights available to address varying power densities and space constraints. - Simplified attachment options
Thermal tape mounting eliminates the need for mechanical fasteners or PCB mounting holes. - Production-ready extruded profiles
Off-the-shelf designs support fast deployment, predictable lead times, and volume scalability.

Defense & ITAR-Ready Manufacturing
Cooling Source supports defense, aerospace, and export-controlled programs requiring disciplined manufacturing, documentation control, and traceability. Pin fin extruded heatsinks can be produced within ITAR-aligned workflows, including controlled engineering data handling, regulated documentation access, and U.S.-based program oversight where required.
Material certifications, inspection records, and process documentation are maintained to support mission-critical thermal reliability, ensuring repeatability and long-term program confidence.
Cooling Source understands that in defense electronics, thermal failure is not acceptable.
Extrusion Capability Alignment
Pin fin heatsinks are manufactured using precision aluminum extrusion, enabling consistent fin geometry, repeatable thermal performance, and scalable production volumes.
- Controlled extrusion tooling and profiles
- Dimensional consistency across production runs
- Black anodized finish for corrosion resistance and enhanced emissivity
- Suitable for low- to high-volume manufacturing programs
Extrusion provides an optimal balance of thermal efficiency, mechanical robustness, and cost-effective manufacturability, fully aligned with Cooling Source’s extruded heatsink portfolio.
Rapid Prototyping to Production Continuity
Cooling Source supports rapid prototyping through full production, maintaining continuity between validated prototype designs and production hardware.
- Fast-turn prototypes for thermal and mechanical validation
- Engineering support for fin height, base thickness, and attachment optimization
- Production scalability without redesign or requalification risk
This approach minimizes development risk and shortens time-to-market while preserving thermal performance integrity.
Quality Control & Inspection
Pin fin extruded heatsinks are produced under Cooling Source’s ISO 9001:2015–aligned quality system, with inspections conducted throughout the manufacturing lifecycle.
Quality controls include:
- Incoming raw material verification
- Dimensional inspection of extrusion profiles
- Surface finish and anodization validation
- Final inspection for form, fit, and finish
- Lot traceability and inspection documentation upon request
Enhanced inspection and documentation levels are available for defense, aerospace, medical, and industrial programs.

What I recommend next (strategic, not cosmetic):
- Normalize internal links between this page and your Extrusion, Rapid Prototyping, and Quality Policy pages
- Add schema markup for manufacturing + product category
- Create one comparison table (pin fin vs straight fin vs skived) to improve dwell time
- Repurpose this copy into a defense-specific landing page
You’re building this exactly the way high-end defense and industrial customers expect.
When you’re ready, tell me which page we tackle next.
