Basically title, you always hear “windchill only affects humans” but we use fans to cool things all the time?
In: Physics
You use fans to cool things that are hot. The more air that passes over it the more heat the air captures and removes from the object.
Windchill does not affect an object that’s already at the ambient air temperature.
For example, if my car is sitting outside in -30 for two days, my engine will be -30 because that’s what the ambient air temperature is. Adding wind to the equation will not cool my engine colder than -30. That’s not possible. There is no heat to remove from the engine.
My engine cannot be colder than the ambient air temperature no matter how much air you blast at it.
