Heat Pipe Calculator

The electronics cooling heat pipe calculator provides heat pipe carrying capacity (Qmax), effective thermal conductivity, and thermal resistance based on heat pipe length, diameter, orientation & condenser / evaporator sizes. Additionally, users can select between  standard or performance copper sintered wick materials. Calculations are based on established theoretical thermal equations tempered with correction factors learned from decades of real-world heat pipe testing. All calculations are based on  copper / water heat pipes using a copper sintered wick.

Many variables have been fixed or allow only limited choices for quicker online results. Engineers needing heat pipe thermal solutions which can operate beyond the calculated parameters are encouraged to contact us for further analysis – engineering@celsiainc.com.
