HiK Plates/ Heat Pipe Assemblies

Copper/water heat pipes are made of copper, use water as a working fluid and typically operate in the temperature range of 20 to 150°C. ACT manufactures copper/water heat pipes into two basic geometries: Tubular Heat Pipes and Planar Heat Pipes. The tubular heat pipes typically have outer diameters from 1/16″ (1.5mm) to 1.5″ (38mm). Custom diameters can be manufactured per customer requirements. The planar heat pipes are also called vapor chambers which are used as heat spreaders. Copper/water heat pipes can be combined with other components to form heat transfer assemblies.

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.

Examples of Heat Pipe Applications:

  • Heat pipe heat sinks for electronics and energy conversion device cooling
  • Embedded heat pipe heat spreaders for electronics cooling for military applications, medical devices, power electronics, spacecraft, and more
  • Heat pipe heat exchangers for electronics enclosure cooling, waste heat recovery, and chemical process temperature control
Copper block-pipe-fin assembly.
Block-Heat Pipe-Fin Assembly. The heat pipes transport heat from electronics mounted on the block to a series of fins. Fans mounted over the circular openings supply air to cool the fins.
