Interesting new type of TEC in development + help needed

[hixie]

I really don't know if this is the best place to post this cause i want some feedback from the phrase change and cascade people aswell as the watercooling people. So hope you guys could help spread the word to those guys.

I'm developing a new type of TEC (if you can call it that). It's basically a heatpump like the TEC, but the difference is that instead of directly using a current to transfer the thermal energy. It uses the electricity to work an airpump in a closed circuit. When the air passes over these chemicals this move thermal energy from one side to the other. Just like a TEC. However, instead of using something like 20A it uses 2-3A to power the airpump.

My question is, would this be an advantage for the phrase change people and the watercooling people. I, myself am a watercooling person so i know this would be a thing i would like, but what about the phrase change people would this useful to them?

Lastly, anybody who has a good knowledge of refrigration, chemistry or evap/block design would like to help. Or think they have something they have some skill or knowledge that would help. Send me a PM. I'll give you more details then.
I currently have 2 other people working with me. One was a university student who actually worked on this type of heatpump, and the other is a guy who is interested in investing some money into it.

Any comment, suggestion or help would be apperciated :)

Got any drawings on how this works?

[MaxxxRacer]

sounds interesting.. with it drawging 2-3 amps is it comparable (in terms of performance) to a TEC drawing 20amps?

[n00b 0f l337]

I don't think it would be comparable. What you put in is never more than what you get out. Tec's may not be the most efficient but this won't be that efficienct either. Its just a heat pipe but bigger and requiring an air pump.

I dont have any comments or suggestions, but I would like to wish you luck!

i dont see how you would be able to get sub ambient results on one side without a mechanical pump or a chemical reaction (has anyone thought of using a sustained chemical reaction in a closed loop to cool one end and heat the other before or looked into the idea?). in such a system, i dont think evaporation in a small unit would yeild sub ambient results. could you please pm me the details?

sounds like an interesting project though. best of luck :)

Cirthix, the airpump pumps air back and fort over a combination of chemicals which triggers a chemical reaction. Which in turn moves the thermal energy. The sole purpose of the air is to trigger the reaction between the chemicals.

I'm still waiting for the exact combination and formulae of the chemicals needed. Then i would need someone who is good with chemical or mathematic equations to calculate exactly what combination and amount is needed to acheive a certain level of capacity. Anyone good at that here?

Saying that it would require 2-3amps is very generous, my uni friend said that he just slowly pumped the air by hand and managed to get just above 0C from an ambient of 20-25c i think.

Lastly, its not a heatpipe. A heatpipe just has very high thermal conductivy, when bothsides are thermally balanced then no work is done. A heatpump uses some sort of energy to move thermal energy from one side to another. Causing a hotplate and a coldplate.

How do you plan on getting rid of the heat? This is in interesting way of transferring heat, discussed it a bit with a friend a while ago, but didn't go into the details of which chemicals to use, and we ended up at the problem of whether the radiator used can disappate the heat fast enough, considering the possible high efficiency with this method.

[Mr. Tinker]

a reaction might use energy, which could be in the form of heat, so that's somewhat plausible. The only problem is that I suspect that you'd constantly be losing chemicals.

[littleowl]

sound cool but I cant see it working very well!! can you give pics to explane some more

[hixie]

RTB, thats where the feedback from watercooling and phrase change people are needed. I was thinking about making two version at first. One for the phrase change people where it is a heatpump and an evap in one. The second is for watercooling, which has a heatpump and a waterblock attached.

Mr. Tinker, you're correct. I just hoping that the chemicals will last a few years, or that it is a reversible reaction. That reverses when the airpump is turned off. Like i said before i havn't gotten the exact formulae yet so i can't really say.
As soon as i get the formulae, i'll try and scan a few drawings or draw a few in photoshop.

[cirthix]

ah, so you're setting up a closed loop of chemicals, with the air pump just moving it around and using a series of endothermic and exothermic reactions to do the cooling work? sounds... organic hehehheheheh god i make bad puns lol.

unfortunately, it also sounds very hard to make and i dont see how you can say that the reactions will reverse when the airpump turns off, that just doesnt make any sense.

sounds like a very interesting setup, please pm me with whatever info you have and i'll check it out.

A pump isnt going to produce pressure or compression.

Phase change....not Phrase lol

I'm a Phrase changer look at me
I do Phrase changeinging.
Look my Phrases are changeing
My phrases have diversified

Sorry....I found it hilarious

Damn i look like a moron now. Who cares?

Cirthix i'll send you a PM latter today. BTW the reaction is not endothermic or exothermic. I dont know how to describe it just yet, but the chemicals move energy rather than use it or release it.

if you're in a circulatory system and one reaction is endothermic, the other will be exothermic.

[Jochenp]

Aren't reactions ALWAYS endo- or exothermic?

[wittekakker]

What's the defenition of endo- and exothermoc reactions? Maybe this is your answer as well :)

Endothermic uses energy, exothermic expels energy.
Ex: Evaporation is endothermic, it takes energy while happening, and a fire is exothermic, it creates energy while happening.

[cirthix]

yes carlz0r, tha'ts right. however just to nitpick, it's a conversion of energy and not a creation ;)

i got a pm from hixie with some info, sorry, but this just isnt going to work.

And creating fire is endothermic :D

Then it might be time to take the investment money and run ;)
