Your communism sounds like capitalism. Sorry, no interest in producing heat sinks; I need to make 4 for something. I could buy them but I want to play with a concept on the mill. I am interested out of general metal trickery.
Okay, since it's you ...
Firat off, I think the sinks he is modelling are crap. There's a ton of research into fins and heat transfer, mostly from the thirties and radial aircraft engines. One really
important thing is the fillet at the root. These are square. Bad. Skived ones have no root fillet, bad.
Taper on the fins was desirable but not top-level necessary.
Closer spacing was helpful but requires that air be directed through
the fins, not just past them. That's why the sheet metal baffles between the cylinders on a radial.
And last, something recent maybe ? Is that interrupted fins, like staggered, so the air has to flow in a drunken goose path at a slower speed, made heat transfer better.
So everything about the op's except for the profit margin can easily be improved.
If it wuz me, and only four special sinks I wanted to be highest performance ? You could investment cast them, edm them, mill them, forge them. Forging would be most fun. And silver is slightly better than copper so for four dinky ones, I'd use that. Forged silver heat sinks, now we're talkin dodge charger
And oh yeah, more important than all the rest, make sure to force the air through
the heat sinks. Shielding is necessary. Seems like this project is mostly an advertising exercise.
About the communist thing, you guys musta had pickles for dinner or something. Communism is just a planned economy. If the village has 800 people and each of them eats two pounds of pizza a day, then you want to have 11,200 lbs of pizza in stock every week. So you line up the wheat, the tomatoes, the ovens, the delivery boys, and the beer. In capitalism you don't give a crap how many people there are or how much they eat or where it's going to come from, you just figure some greedy bastard will figure all that out for you if he thinks he can make a buck.
You can probably see the advantages and disadvantages of both pretty easy.
That's really all there is to it, the rest of this stuff is pure fruitcake paranoia.
