WebOct 11, 2024 · The air touches the heat sink/radiator, and it picks up heat by conduction. Then, the hot air moves out of the way so that more cool air can take its place. The mechanism that moves the air can be convection (if it's a passive heat sink, or if I leave the ceiling fan switched off in my bedroom), or it can be forced by a fan. – Solomon Slow WebAug 26, 2024 · Convection works when a liquid or gas is unevenly heated.

When a fluid such as air or water touches a hot object, it can heat up and then move in bulk as a fluid, thereby carrying the heat quickly to new locations. Hot air rising is a common example of heat convection. For this reason, "heat" and "hot air" tend to be confused with each other.
