Heat Sink Design

In today's high power dissipation applications and ever-shrinking chassis sizes, the use of off-the-shelf heatsinks for cooling critical components is becoming a rarity. OEM vendors are increasingly turning to thermal design outfits for custom heatsink solutions. CATT specializes in the design of high performance heatsink solutions for a wide variety of industries. Today, our heatsinks are in use in a variety of applications including:

  • High density compact PCI and telecom enclosures with slot sizes down to 0.6U
  • 1U Server enclosures
  • Outdoor cabinets
  • Fuel cells

Because our heatsinks are customized to the application, we ensure the most effective use of available space for localized thermal management. Our flow and heat transfer experience guarantees that the best performing heatsink is designed the first time around. Backed by our system-level thermal management expertise, our heatsink design and analysis covers not only your normal operating point but all postulated installation conditions and cooling system failure scenarios. Our expertise in heatsink design includes:

  • Cooling of high power process to 300W/cm^2 and beyond
  • Passive and active heatsinks
  • Heat pipes
  • Heatsinks with integrated heat pipes
  • Heatsinks with integrated EMI shielding features
  • Liquid cooled cold plates
  • Micro-channel liquid cooling
  • Integrated air and liquid cooled systems

Our breadth of manufacturing experience ensures that you get the most cost-effective and reliable solution. And because our designs are created and analyzed in a full 3D CAD system, our geometrically exact models can be exchanged in your favorite CAD format for full form and fit checks with your system and board designers. Our manufacturing capabilities include:

  • Rapid prototyping
  • Folded fin designs brazed or bonded to base plates
  • Skiving
  • Special machining and stamping to incorporate complex features
  • Folded fins with specialized surface transfer enhancements
  • Aluminum and copper brazing
  • Low to very high volume manufacturing
  • World-wide manufacturing capacity ensures reliable delivery and low freight costs
