Peltiers from Apple,new surplus, w/heatsink 4:$19.00 + shipping

[guitronics]

Here's where you can get new surplus Peltiers from Apple's PowerPC 601+ Computer. Peltiers

The website:Click on technical stuff.They list the Peltiers at 3 for $25.00,but tell 'em you saw the special of 4 @ $19.00 in "Nuts&Volts magazine,June 2001".

Don't buy 'em off the website,call their toll-free number 1-800-227-3971. There's a $25.00 minimum order, not including shipping.

Their claim:"We are the oldest and largest recycler of refurbished Macintosh and Apple II equipment in the industry!"

I found some Peltiers by following Mac Parts / Technical Stuff:
3 for $25 for PowerPC 601+ processor

Didn't quickly spot 4 for $19.

Anyone care to linkify it, exactly?

Sorry, nekote...you are FAST! I had to edit, preview, post, re-edit, etc. I have it all 100% correct now!!!!!I bought a box of 'em from them.They'll work from 12V, and even 5V.They work better, of course from 12 V.D.C...I believe these have a maximum voltage (Absolute maximum!) of 15.4V.D.C...

I need to call the tech guy back to get all of the specifications,like how many amps do they draw at max. volts.

The only thing with peltiers is they use quite a bit of Current(amps) and require a well-filtered power supply.(Not a lot of ripple).

They were first used commercially, to the best of my knowledge, as "Refrigeration units" in automobile "iceless"coolers.So they work fine from a car battery!

HAHA! My car will now power my PC!

guitronics,

I'm only familiar with the overall concept of a semiconductor somehow consuming electric energy to transport "heat" from one side to the other, making one side colder and the other side hotter.

Where (URLs) can I learn more about Peltiers, mostly categorically speaking? Some practical stuff would be nice, too. What are the units of measure? BTU/watt? How is this described / measured / designed for?

For example (if this is even phrased correctly), how many watts input produces how many watts of cooling? Any sort of rules of thumb? How (in)efficient are they? Can they literally "make ice"?

Are Peltiers, generally or for these particular units, waterproof such that you could use water as the "working fluid", rather than direct contact (conduction) or air?

Is the Peltier more efficient (capable of more "cooling&quot if the hot side's temperature can be kept lower rather than warmer? ......

TIA for info to help quench (cool) my curiosity!

Anyone know if these can be rigged up on any AMD or Intel chips? Probably worth $20 to find out I suppose.

if u don't know what u r doing, don't play with a peltier... u can cook your cpu in a minute... u need to be able to dissapate a heatload of the combination of the pelt and the cpu... generally this requires a big, high quality heatsink and loud fan or, like i use, water cooling...

don't know why i got 3 posts... there are also condensation issues that need to be dealt with or u will fry your mobo and cpu... go to www.tedist.com to learn...tedist

ECHO....echo....ec...


Teraeric: Understood, I would not just plug it in and hope for the best. I will test first, but need to know if it would even be feasible to attempt to hook this unit up to another type of chip. I can do a lot to customise the mounting if neccesary, but if the contact surface will not work for some reason, it would be in vain.

Guitronics - Please let us know what you find out. I'm also curious about the dimensions of these peltiers and any other specs you might be able to learn.. I'd like to buy some just to play around with, not for PC cooling applications. But I don't want to get them to find out that they are like .25" square or anything like that. If you get any concrete data, it'd be appreciated! (don't want to piss them off by having 400 anandtechers calling in to ask...)

if anyone buys a set of these, would they be willing to sell me one?
