Thermal Resistance Calculators

Have questions? Solving difficult thermal challenges is what we do.

This page offers sizing & thermal resistance calculators for heat sinks and heat pipe / vapor chamber cooling solutions. Engineers can utilize these tools to estimate required heat sink size, power handling capacity, and thermal resistance values, aiding in the design and optimization of efficient thermal management systems.

Heat Sink Size Calculator

Estimates required heat sink volume & dimensions based on power input, Tcase, ambient temperature and available airflow. Useful during early design phase.

Heat Sink Performance Calculator

Compare heat sinks using a solid metal base to those using a vapor chamber base: heat sink thermal resistance & delta-T for each part of the heat sink.

Heat Pipe Calculator

Calculates heat pipe carrying capacity (Qmax) and thermal conductivity based on power input, heat pipe length, diameter, orientation, & condenser/evaporator sizes.
