Heat Pipe Calculator

This program will give a performance curve of a traditional copper-water heat pipe with the given input values. This curve is a guide to help estimate heat transport capacity for ACT’s copper-water heat pipes using common wick structures.

If your temperatures require materials other than copper-water or this guide does not provide results that meet your requirements, please contact our engineering experts, as they have years of design experience. They will be able to tell you if heat pipes are appropriate for your application, and will work with you to determine an effective solution.  Additional design resources can be found at the bottom of this page.

If you have difficulty with this calculator, please email us at Solutions@1-ACT.com with your input values or watch this use case example:

Please input the following information, referenced in the picture above:


Value for Heat Pipe Length

Value for Evaporator Length

Value for Condenser Length

Value for Height Against Gravity
