Welcome to the World of Aavid Heat Pipes As a pioneer in heat pipe technology and their application, Aavid Thermalloy has developed a high quality manufacturing process to ensure long life and reliability in our heat pipes. We’ve had over a decade of experience designing and fabricating heat pipes and heat pipe assemblies. Heat Pipes are great thermal energy transporters that use an evaporator and condenser in place of a solid conductor. While they don’t dissipate heat themselves, heat pipes quickly move heat from one area of the heat pipe to another area. The aerospace industry has been the proving ground of heat pipe reliability, and has been used for decades in harsh and demanding environments. Efficient Heat Transport Air Cooling Heat pipes are great at moving or spreading heat, especially when embedded in a base plate. They can quickly move heat away from temperature sensitive devices to a place the heat can be dissipated. Heat pipes can also be used to increase fin efficiency by moving heat directly to the cooler top portion of fins. Many types of applications can benefit from heat pipes.

Discover the Potential Heat Pipes Have to Offer! How do Heat Pipes Work? A heat pipe is a closed evaporator-condenser system consisting of a sealed, hollow tube whose inside walls are lined with a capillary structure or wick. Thermodynamic working fluid, with substantial vapor pressure at the desired operating temperature, saturates the pores of the wick in a state of equilibrium between liquid and vapor. When heat is applied to the heat pipe, the liquid in the wick heats and evaporates. As the evaporating fluid fills the heat pipe hollow center, it diffuses throughout its length. This...

Discover the Potential Heat Pipes Have to Offer! Heat Pipe Exploration and Discovery Kits Aavid’s Heat Pipe Exploration and Discovery Kits are designed for you to get your hands onto our heat pipes to get a feel for how they work, what they do, and try them in your own application. Assemble, bend, and rough together a prototype for your latest application then contact us for help with your design. We can fabricate prototypes with tighter bends in our quick turn shop or go to production in our worldwide manufacturing facilities. Heat Pipe Exploration Kit - Part #: 056325 Heat Pipe Discovery...

Discover the Potential Heat Pipes Have to Offer! Pipe Forming or Shaping Heat pipes are easily bent or flattened to accommodate the needs of the heat sink design. Forming heat pipes may affect the power handling capability as the bends and flattening will cause a change in fluid movement inside the pipe. Therefore design rules that take into consideration heat pipe configurations and the effect on thermal performance ensure the desired performance. Pipe Flattening Bending heat pipes by hand can be tricky since it’s easy to collapse the pipe. The diameter is what will define the centerline...

Discover the Potential Heat Pipes Have to Offer! Heat Pipe Assemblies The Heat Pipe Exploration Kit includes basic interfacing hardware between heat pipes, devices, and cooling solutions of your choosing. Each aluminum evaporator and condenser has a tight channel and matching screw on caps to clamp down onto these heat pipes and minimize thermal resistance from the gap between the pipe surface and channel groove. Matching the heat pipe diameter to the correct sized evaporator and condenser will provide the best thermal connection. Depending upon length, your interface resistance ((m2K)/W )...
