High Temperature Heat Pipes

High temperature heat pipe technology satisfies demanding requirements in aerospace, chemical processing, annealing, furnace liner isothermality, semiconductor material crystal growth, oil-shale extraction and a wide range of high-tech electronics, heat dissipation and heat uniformity applications.

​

For efficient high-temperature (300°C to 2,000°C) heat dissipation, thermal spreading, high-heat flux cooling and other high-temperature heat management challenges, High-temperature PTFE lined pipe are the thermal solution of choice.

High Temp Heat Pipe Materials and Applications:

High temo lined pipe materials of construction are typically Alloy for PTFE,Cesium, Potassium, and Sodium. Our also manufactures a Haynes 230/Sodium heat pipe for extended operation near 1100°C because of the significantly higher creep strength. Austenitic stainless steels can be used for applications that are at the lower end of the temperature range.

Typical applications for high temperature heat PTFE lined pipe fitting include the following:

• * Heat Engine Receivers (Steam, Stirling, Brayton, Rankine)
• * Solar Thermal
• * Heat exchangers
• * Hypersonic wing leading edges
• * Waste heat recovery
• * Nuclear power
• * Thermoelectric Generators
• * ​Isothermalizing furnace elements

How are High Temperature Heat Pipes Used?

High temperature heat pipes can be used to build custom heat transfer devices for both high power throughput and precise temperature uniformity. Power throughput in the 1 to 100 kW range is typical. Precision heat treating and materials processing furnaces are capable of extraordinarily precise temperature set points and isothermality. Set point accuracy, stability, and isothermality of ± 0.1°C is common with a single heated zone, using an off-the-shelf temperature controller.

Because of the inherent temperature uniformity and stability of high temp heat pipes, they are an integral component in nearly all of the most precise temperature calibration instruments in the primary calibration laboratories around the world. This technology can also be applied to research, commercial, and industrial applications for processes such as annealing, sintering, crystal growing, brazing, and controlled diffusion.
