The heat pipe calculator provides heat pipe carrying capacity (Qmax), thermal conductivity, and thermal resistance based on heat pipe length, diameter, orientation & condenser / evaporator sizes. Additionally, users can select between standard or performance 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.

As with any model, we strive to be as accurate as possible. Yet, it’s just a model. CLICK here for a guide on how to use this calculator.
