What is another term for a natural convection system?

A natural convection system relies on the natural movement of air due to temperature differences, where warmer, less dense air rises, and cooler, denser air descends. This passive movement creates a circulation pattern that allows for heat exchange without the need for mechanical assistance or external power sources.

In this context, "passive system" accurately describes the characteristics of natural convection. It emphasizes that the system does not use energy-consuming devices, like fans or pumps, to facilitate air movement. Instead, it relies solely on the fundamental principles of thermodynamics and gravity.

Other system types, such as active systems, involve mechanical components to control the flow of air or liquids, while forced systems specifically utilize mechanical methods to induce air movement. Hybrid systems combine elements of both active and passive methods, but a natural convection system strictly does not operate with mechanical energy, making "passive system" the most fitting term.
