Integrated Chiller Assist

[madman]

Have nay bros out there heard of the "integrated chiller assist"? Saw in reefcentral. Works on heat sunks etc. Dun really know how it works. Wan to diy one but dun exactly knows how it works. Any bros out there know? Or interested to diy it together?

[supremo]

bro, saw the thread that you're talking about, but honestly didn;t understand what the guy was talking about. I understand he added something to his nanotank and that's it. If anybody knows what the guy means, some enlightenment would be much appreciated by bro madman and mtself.

here's the link

That is a TEC(thermo electric cooler) aka peltier, overclockers use it with a water-cooling kit to cool their CPUs.

IMHO, its best for tanks below 2ft.

If the hot side of the peltier is not cooled properly, not only will there be no cooling effect, the until will also get damaged.

don bother dude.. i've tried sourcing for peltiers in singapore and it's not worth the time and money...

Bros, thanks for the reply. I've searched and found something under "heat sinks". Came up with an idea, wonder if it will work better for my 2ft tank than my fans blowing at the water direct. Think the only plus point is that it will lessen the evaporation rate.

Comments from bros out there please....

DOnt borther dude... i have had peilter in my comp. The cold side freezes... you cant connect a themal state on to it so you cant control the tempreture.

Hahaha... using a cheap Chiller + a Raidiator to DIY an aircon sounds more fun.

P.S: Peilter chip cant last long.

Thanks for the reply bro. Considered it again also. Think not worth the afford and $$$. Anyway my 2 comp fan working well. Able to maintain temp at 28dg. On good days can hit 26-27dg oso..

a normal heat sink definitely works differently from a peltier. it's also different compared to blowing a fan onto the water surface.

The driving force for evaporative cooling is humidity difference. the water surface is at 100% humidity while the environmental air is less. therefore the environment attempts to pull water vapour away from the 100% humidity area on the water surface, and in turn the air on the surface pulls water vapour from the water itself. In order for the water to become water vapour it pulls heat from the surrounding water molecules and that is the reason why your tank cools down.

For a heat sink the driving force is temperature difference. there must be a temperature difference between the block and the surrounding air before heat transfer can occur. And in singapore if the air temp is 30deg and your tank is at 26deg, a normal heat transfer block will actually be transferring heat into your tank, no matter how hard your fan blows. In fact, turning the fan up will further increase the rate of heat flow into your tank.

so in simple terms a normal heat sink may not work, especially in singapore...

cheers...
