Anodizing cooling units? Effect cooling?

[chromo]

I am wondering how anodizing aluminum effects cooling, if it does at all even.
So many things are made from aluminum to be used for cooling, Computer heatsinks, car radiators, etc..

In reading up on the process ALLOT, I see it said the anodized layer is less conductive of currents. Layer is supposed to be a bit stronger. Also anodized layer I read can withstand a blow torch for a short time, probably very short.
So how does any or all of this effect the aluminums ability to remove heat and radiate it into the air flowing by.

Is there even any reason to think or worry about it?

It's miniscule and not to worry about. As you yourself said there are many things made of aluminum to promote cooling and have you noticed the majority have probably been anodized. ie: computer heat sinks

OK thanks.

I did notice on some things they are anodized, like my battery charger maybe, but it's a large oversized aluminum part as much for looks as it is a heatsink. I wasn't sure about other stuff.

Ok, I'll be doing some cooling related parts then.
Thanks.

Chances are if its metal, and it isnt some type of metallic silver or gold, its anodized aluminum.
