Hi=20 Dave,
 
I've always=20 been interested in trying to air cool the oil in the pan.  As=20 I understand it, there's a limit to what you can do with a heat = sink like=20 this, due to the fact that oil will thicken when cooled.  This = means=20 that the oil in contact with the pan surface will cool, then cling to = the=20 surface, preventing the hotter oil from touching the heat=20 sink.  
 
Now I'm sure=20 this only happens to some extent, so there's still considerable cooling = done,=20 but it seems like it would be much better if you could find = a double sided=20 heat sink.  In other words, one that has fins = sticking into the=20 oil, and out into the air. 
 
Has anyone=20 ever seen double sided heat sinks?  
 
Cheers,
Rusty
