Cool tank

[powersensor]

Hi guys,

The thermoelectric thing is actually called Peltier. It runs on DC power (low voltage but consume significant amount of current) . When operating, one side will be cold and another side will be hot. It is hard to find in M'sia.

It is mostly used by computer enthusiasts in the overclocking scene to cool down the overheated CPU. Other applications are portable car mini fridge, cup warmer or cooler, etc

I have done the same setup for my n.rajah last time but it did not work well.It just cooled few degrees.When doing simulation like urs the temperature go down to 10c.I tried reducing the water amount in my tank,but no success.My tank was at balcony.Hope you have better luck then me.

Eric,

For the benefit of all who want to build one like yours, please give us a schematic layout diagram.

Question: why do you need a heat sink for?

There is a shop in KL near the Pudu market that sells and do products dealing with acrylic. I have seen acrylic tubes in the shop before but not sure of the thickness.

Now this tank is getting more and more cool.........what are acrylic tubes? I don't know any difference between lights, like florescent tubes.

Cheers

This may not the final version, as I still discover some weakness need to be improve. Will provide diagram for all once I am satisfied on it.

The heatsink work as cold plate.

The acrylic tube that I am looking at OD 2 inches x length 20 inches, thickness don't matter.

I only know the electronic street and aquarium street. There is complicated for me.

Acrylic is Polymethyl methacrylate (PMMA), a plastic commonly we called.
Clear mean not color and transparent. I need it to isolate the heat from light transfer in to the tank. Otherwise tank will be a mini macro wave when the light is on without cooling, my plant will be cooked.

Others "plastic" as below.
Polycarbonate (PC)
Polyvinyl chloride (PVC)

I saw ready made acrylic tube - 50mm X 1m for about RM100 at a stationery/ art supply store here in Penang this afternoon. Custom order requires high volume according to the sales assistant.

Hope this is helpful.

Thanks Athene, that is so expensive as out of my expectation.
Today I went to Pudu Pasar round, found a sticker cutting shop selling it too. 50mm x 2m = rm110. Must sell on 2m length. Now I heard and check with car accessory shop, they might had short one to some people put blue or red fluorescent light under the car.

Found some one from canada selling rm6.26 per feet at ebay. Postage + handling charge around USD10. But now Christmas session, afraid of postage matter.
