High Temp. Heat Pipes

Thermacore’s high temperature heat pipes are used in a wide variety of applications and service conditions from the ocean floor to geosynchronous orbit.  These high temperature heat pipes have improved processes as mundane as glass making, as industrial as oil-shale extraction, and as high-tech as epitaxial deposition. 

With over 30 years of high temperature alkali metal heat pipe design, development and fabrication experience, Thermacore’s liquid metal heat pipes have set new records for heat transfer in hardware developed for the National Aerospace Plane’s leading edge, solved day to day problems in state of the art automobile spark plugs, and solar power Stirling engine receivers.  If your product or process involves high temperature heat transfer, or involves high heat flux cooling, Thermacore has the design and fabrication experience required to provide the best thermal solution.
