Cooling

[mike89]

does anyone know of a device that decreases in temperature as electricity runs through it?

[Tormod]

A fridge? But...seriously, I don't think it is possible since AFAIK electricity produces a little bit of heat when it passes through something.

[mike89]

well thats what i figured, there would be nothing, but there are may things that i have found that i did not know existed so i was just wondering

[chatlack]

There is a thing to cool the processor of the cpu. But it only cools one side. It transfers heat to one direction. But you can say it cooling..

Cooler paste or a heat sink does not cool an object due to electricity but because the material leads heat away from an object being heated by electricity. There is no current running through cooler paste.

I don't think there is any mineral/material/substance on Earth that will "decrease in temperature as electricity runs through it". But if you find one I'm sure you'll win a Nobel Prize ;).

[mike89]

i might have to work on that one then ;)

[chatlack]

You are wrong tormod. I dont tell the past. Its name is Peltier Coolers. When electricity runs, it transfers the heat one way...

if you could find what exactly it is or give me a link it would be really cool!

Hmm, makes me wonder about einsteins design for a refridgerator.

[bumab]

no moving parts, but it wasn't the current that cooled it down.

The Peltier cooler is different from the fridge patented by Einstein and Szilárd, however they are both heat pumps. They can absorb heat from a substance at low temperature and dump it in a substance at higher temperature plus the extra energy required by the 2nd principle of thermodynamics. The Peltier cooler is just a pair of thermocouples.

Peltier cooler. The active p-n junction elements are electronic crystals (large electrical conductivity) but phonon glasses (low thermal conductivity).

This is becoming interesting.

 

The cryogenic creation process differs conspicuously from conventional code of belief.

 

Cold Creation Vs. Modern Cosmology

 

I'll be back.

In 1995 the 2001 Nobel Laureates succeeded in attaining this extreme state of matter, Bose-Einstein condensate (BEC). Eric A. Cornell and Carl E. Wieman then produced a pure condensate of about 2 000 rubidium atoms at 20 nK (nanokelvin), i.e., 0.000 000 02 degrees above absolute zero. Collective excitations and vortex formations have since been observed in condensates.

 

Manifestations of Bose-Einstein condensation have previously been observed in more complex systems: condensation of paired electrons in superconductors (where loss of all electrical resistance occurs) and superfluidity or suprafluidity (loss of internal friction in fluids). Both manifestations occur at very low temperatures.

 

But there is more. Due to Poincaré resonances, dynamical processes at higher temperatures also lead to long-range correlations, despite the short-range character of forces between particlesæan essential fact that leads to asymmetry and permits evolutionary patterns in agreement with the thermodynamic description of nature.

 

something has only just begun

I'll just point out that the system does not get cooler or colder, it does work to move heat from one place to another.

 

The energy in creates heat, but at the same time moves the heat from a warm place to a warmer place, plus the heat from the electrical heating in the cooler.

 

To do otherwise would break the Second law of Thermodynamics, as the work done would be over unity.
