Looking for a Better Metal or Alloy for School Project

Look at the thermal conductivity of different metals in this table. Generally speaking your best conductors will be: Gold, Silver, Copper, Aluminum. What can you afford?

Do NOT forget a good thermally conductive paste. Again, there are different options, based upon your budget.

Thank you for the info. I do have a good thermo paste between the aluminum, TEC and heat sink. The table will work great.

Thank you and yes, you are correct i do need to transfer heat.

GA from me.

The uneducated will never fully understand that important point.....

It is similar to the idea that a vacuum pump "sucks". They don't. They pump gas out, not "suck" it in. Some people never get that point either!

Aerogel is pretty expensive. Styrofoam is cheap and a very good heat insulator. Just sayin'.

As you probably know, the TEC is a heat pump. An important part of cooling is removing the heat from the hot side. A good finned aluminum heat sink connected to the hot side with thermal grease is essential, and if you can arrange for the fins to be immersed in a water bath to carry the heat away faster, that would help.

I never thought of immersing the heat sink in a water bath, What I am looking in to is those cooling system that are are water based or use coolant for CPU overclocking, kind of like a radiator on a smaller scale.

If you choose a water cooling solution, get some liquid that does not freeze, like glycol. That way you can have a clean closed circuit.

Interesting, and good point!

A simple cheap and effective method of cooling a moderate size volume of something with a minimal sized heat transfer point is simple convention of the primary medium which in your case is air.

If it was me I would be looking at a simple common computer processor heatsink with a fan on it as the cold side heat absorption system.

For the hot side the bigger the heatsink and better the airflow the better that way you are maximizing the Peltier cooler units temperature differential limits in favor of how far below ambient the cold side can go.

As for insulation unless you're in an extremely space limited design restriction common styrofoam is plenty sufficient. At worst a sandwich layer design of alternating thin sheets of styrofoam and aluminum foil backed bubble wrap like Reflectix of similar thicknesses does very well since it both insulates from conductive and radiative based heat energy transfer.

As for the wine I hope you're drinking it because you like it and not because some wine snobs said it's good.

Wine snobs are faking it.

Thank you for the tip on making a sandwich layer of styrofoam and aluminum foil.

Copper is good, but copper flashing not cheap either.

"...Pure copper...is easily machined..."

.

er...what? Pure copper is a royal pain in the ass to machine. It is far too maleable. It flows as much as it cuts. On top of that, it work hardens easily. It loves to grab tools and clog abrasives.

Are you used to using EDM on copper or something?

They have kits on the Ebay for cheap.....

I have a similar set up, the TEC is thermo pasted directly to the aluminum enclosure and is then screwed into the heatsink. i think i will try having another heat sink on the cold side with the fan. that may work well

Yes having the air moving increases the heat exchange rate....

Aluminum is what is used the most. Cost less then the other metals. First though have you done the calculations. Is the TEC capable of removing more heat. Air flow would also help. You can buy cooling fins already made.

Just to be clear, this project is not about cooling a bottle of wine down from say room temp, but just keeping at some temperature below ambient, correct?

A TEC is probably up to the job of keeping a bottle of wine at a cool temp with sufficient insulation, but cooling a bottle of wine down in an expedient manner is a much bigger task.

Yes, it is just to keep the wine at a specific temp below the ambient.

could examine/reverse engineer and improve on something like this-<http://www.kitchenkapers.com/waring-digital-wine-chiller-and-warmer.html?src=bngshp>

What about Pd (Palladium)?

Also AK47 has very nice heat transfer

It would be nice if he had a better working model of the AK-47, as that one is a crying shame. Yes, the bacon was apparently cooking, but when I want bacon rolls, I just roll them up on a plate and nuke them in the microwave.

I love me some bacon, and I hope you do too!

Another point: Why not just put an outer wrap of aluminum foil to retain more heat, rather than the contamination of that baling wire?

Could you turn that into a link, perhaps?

Palladium is a nice clean metal, and is a good conductor of heat and electricity, but the cost is still out of most people's ken.

DETERMINATIONS (INCLUDING SPECTRAL EMISSIVITY AT 684.5 nm) AT THE MELTING TRANSITION AND IN THE LIQUID STATE

By Claus Cagran and Gernot Pottlacher

That's a citation, not a link.

Congratulations. Ehhh, you do not know what to do with the citation ?

Really is easy

Yeah I have to use a search engine to find the original documents. I've been here a while. You? We try to help each other here. If you can't be arsed, bugger off.

"School project"; "Wine cooler"!; ?

Wish I'd gone to your school.

We don't like cheat sites!!!!

WARNING! SPAM FOR A CHEAT-SITE!

".. I will write my essay for me on Nickel as it is one of the best metals to choose. ..."

'I will write my essay for me...'. Awkward. Whoever has you write their essay after that odd display of word choice will likely get exactly what they deserve.
