TEG? Use both side or one?

post #1 of 6
Thread Starter 
Long story short, to use a TEG, would you actually need to cool the cold side proportionally to the heat on the hot side or is just a good heatsink on the cold side and hot side on the stove?

And this can be done on any TEC?



Note: Recharging a battery even possible?

:***: Uhh.. I think you dont get what a TEC does.. It basically gets hot on one side, cold on the other. The cold side goes on the CPU, the hotside you attach watercooling (usually). Unless you get a crappy TEC then you will usually need watercooling to cool the hot side. But if you do get a lower-model TEC then having a hs on it and a good fan may be able to handle the heat.

No, I'm talking about a TEG. Thermoelectric Generator not Cooler. This follows the Seebeck Effect, not the Peltier Effect.

This is a unit like the peltier but you have to heat the hot side and cool the cold side. The greater the dT the more current you get. What I want to know from people who are more knowledgable is if I have to actually cool the cold side alot or just keep it form heating up while torching the hot side to achieve the maximum dT and thus my current.

You will need to keep the hot side hot and the cold side cold, you want the maximum deltaT (∆) that you can get and then you will achieve a greater current

EDIT://

The dT (∆) is the difference in tempature between the hot and cold side.

Ohh and ehhhh....NO, you couldn't recharge a battery using a TEG, that is unless you can control the tempature's....and i mean to .00 of a degree!

I saw TEG power lighbulbs so why not a battery? I assume using the charger in conjunction with the TEG would allow you to do this? Put a certain resistance and as long as current goes over this value then boom you can control what you need.

That depends on the battery. You cant just feed power into them any more, like you could with the old lead-acids and, to a lesser extent, nicads. You need to manage some complicated charging cycle systems, voltage and current regulators. Li-ions are the worst, you need a microcontroler to charge them properly. Fortunatly, you can easily find schemetics for a charging circuit or just buy and strip a charger to get the parts you need. If your charge control unit is good, you just have to feed it enough power at about the right voltage. A TEC could do that.

Why you might want to I have no idea, unless you happen to live next to some very hot hot-springs.
