I've got a question about air temperature for the brain trust out there.

Some of the comments I've gotten about my cold weather misfortune concerned
the cold temperature AND the VERY strong winds that occurred a couple of
nights ago.

Some people mentioned the wind chill factor being a reason that the coolant
in my system might have frozen.

Someone please set me straight on how this can affect the freezing of water
in the cooling system?

I always thought the "wind chill factor" had to do with the perceived
temperature as it related to us humans.

I mean . . . Sure. . .some cold air whipped up by strong winds will act
sorta like a convection oven in reverse, and speed up any thermal energy
transfer . . .  but it can't actually cool something (or at least a DRY
something) down below the actual air temperature can it?

An illustration:   34deg air blowing through radiator fins isn't going to be
able to freeze water (pure water) in the radiator is it?  No matter how fast
the wind is blowing.
It may get the water in the radiator down to 34degrees VERY quickly.  But it
can't drop its temperature to lower than 34 can it?

Or is someone going to tell me that the air being forced through the fins
has some sort of pressure drop and therefore temperature drop associated
with it?

Thanks in advance for the upcoming thermodynamics lessons . ..
