Custom Heat Pipes Assemblies are often used for cooling discrete components by moving heat off the chip or sensor to a remote heat sink. Copper/water heat pipes are made of copper typically operate in the temperature range of 20 to 150°C. They are cost-effective, their effective thermal conductivity ranges from 10,000 to 100,000 W/m-K, and the heat transfer is one-dimensional.
HiK™ or high conductivity plates are heat spreaders with embedded heat pipes to transport heat as desired in your system. These plates are particularly useful for cooling of multiple high-power components and managing the thermal load. The HiK™ plate collects and moves the heat from these discrete heat sources to the liquid-cooled edge or air-cooled heat sinks with minimal temperature gradients. As electronics continue to move forward with higher power and smaller packaging, HiK™ plates are a great way to move heat to boost performance. Whether it’s adding more power to the system or reducing the hot spot temperature in hot ambient environments, HiK™ plates provide a reliable, easy to integrate thermal solution.
Current custom heat pipe designs and options include:
- Outer diameter (OD): From 1/16″ (1.5mm) to 1.5″ (38mm)
- Cross-section geometry: round, rectangular or flattened
- Length: any, depending on the application
- Geometry: straight or multiple bends (certain bend radius limits apply)
- Bonding of heat pipes to assembly: mechanical, epoxy, or soldering
- Heat pipe surface coating: nickel or tin
All of ACT’s copper/water heat pipes are designed to survive numerous freeze/thaw cycles without any degradation as required by many outdoor applications.
