Thermal transfer
Here at work I had a discussion with a colleague about heat sinks..
IMHO, the heatsink should be:
1) black (better radiation)
2) smooth (better convection by forced air circulation - no "sticky" layer of air which is basically insulator)
3) it should have fins spaced enough to allow increased air circulation (decreased lamination of layers of air) and large contact surface.
Point 3) is not disputed... but 1) and 2) are questioned.
Anyone has some links which will help me to convince him I am right (or other way around)?
BTW, this discussion may contain another example of counter-intuitive facts in science....
