Enclosure Thermal Calculator

This Enclosure Thermal Calculator is a practical tool to estimate the thermal behavior of enclosures under natural convection. It lets you calculate either:

1. The maximum power dissipation for a given surface temperature.
2. The surface temperature for a given power dissipation.

By entering the enclosure dimensions, ambient temperature, and either power or surface temperature, the calculator gives a quick estimate of heat dissipation and temperature rise under steady-state conditions.

Important Notes:
This calculator is a starting point for evaluating your design. It uses empirical formulas for natural convection, which provide useful approximations. However, it is not a substitute for detailed thermal analysis. For accurate results, use comprehensive simulations or advanced thermal design tools.

Due to design differences between enclosures, we assume there is no heat transfer between adjacent surfaces. This assumption represents a Worst-Case Scenario, where each surface is thermally isolated and cannot share heat with other parts of the system. However, as the number of contact points between surfaces increases, thermal transfer improves, allowing for greater heat dissipation than the values calculated in the thermal calculator.
