Our heat pipe calculator provides a performance curve based on your input values, helping you estimate the heat transport capacity of traditional copper-water heat pipes. It’s designed as a practical tool for evaluating performance using common wick structures in ACT’s standard copper-water configurations.
If your application involves temperature ranges or conditions that fall outside copper-water compatibility, or if the calculator doesn’t meet your specific requirements, we encourage you to reach out to our experienced engineering team. With years of heat pipe design expertise, they can determine whether heat pipes are suitable for your needs and help develop a tailored thermal solution.
ACTâs Heat Pipe Calculator helps engineers quickly estimate the thermal resistance of heat pipes based on application-specific parameters like length, diameter, working fluid, and heat load. Whether you’re designing cooling systems for electronics, power devices, or aerospace applications, this tool provides a fast and reliable way to assess feasibility and performance. Use our thermal modeling tools to streamline your design process and optimize your thermal management system.
