Good peltier block drawings?

mx · 11-13-2005, 10:33 PM

I'm thinking about trying som peltier cooling since I already own most of the parts except a suitable block for a peltier. Currently I'm running a storm block but since it isn't recommended for peltier cooling I thought I would either buy or mill a new one.

I'm taking some courses in milling and I need something to practice milling, so my question is if anyone has a good peltier block drawing to share?

I've tried to understand what's the best cold plate thickness. But I don't get it... :shrug:

The thickess depends on what? Is there any good way to calculate it? how? (I'm taking some thermo dynamics but yet it's pretty basic.)
If there's no good way to calculate it I thought I would start with a thick cold plate and then just mill it down and test what works best for me.

Start with what is know to work. http://www.swiftnets.com/products/mcw5002-AT.asp

Note the drawings and draw your own version and mill it. If you get into milling you will want to learn CAD.

Take the Cascade and storm design threads, and then go see your local manufacturer about whipping up a Peltier based solution. Same concept, just with many, many more jets over the entire peltier surface area. You'll need a decent pump to run it, but then peltiers are OTT so go the whole hog. Might want to consider multiple outlets.

Would a jet block be sensible in this case though? That would be absolutely crazy... but very cool. A good old pin design will make a good pelt block.

And why not direct die?

EDIT: As onto onto hot side of pelt.

that would work because peltiers need alot of compression to get good temps which a direct die would not supply.

Do Pelts need a lot of compression because it changes the physical properties of the metals and makes them more efficient?
Or is it a case of getting really good contact at the interface?

If its the second; then direct to surface should work very well?

The only reason it needs the high compression is so the metal makes solid contact for proper heat transfer. If you don't use metal and just use water then it should be ok. However you would still need some pressure on the other side to whatever you are cooling and it might collapse the TEC if there is nothing on the hot side to support it. Not sure how strong TECs are.
