How to building your own Thermoelectric Chiller

First run doesn't seem promising. I'm making changes to the design and trying again.

The problem with marine tanks is cannot use aluminium heatsink as conductor So not alot of ways to transfer the coldness from the peltier to the water.

let me know the progress...coz im thinking of making one for my 1.5ft*1ft*1.5ft marine tank.

I use the normal aluminium heatsink for the cool side.
The other side heatsink i got it from SLT level 3. I cannot remember which shop but the shop selling 2nd hand electronic parts. i found it from a junk box of heatsink.
The heatsink i bought it at S$10 including fan. Cool plate at S$4.50. TEM at S$19.00. Thermal grease S$1.00.

I bought all these items from different shop in SLT. Just spend you time looking around you may able to find the parts that you want.

hi i tried asking abt the peltier.... ard in SLT ... but most of the shop dun have it... do u might give me the address or unit no. of the shop?

Peltier i got it from SLT basement. I really cannot remember which shop but i'll update again if i go there.....

the shop is at basement, lot number is B1-25, go and ask for 'peltier', don say TEM or TEC, the boss will give u back a "??" answer. They got 8A and 6A module, so, choose urself which one suit u.

xtrekker % Arolee,
thanks for ur info, i will go to find out. maybe i need to print out urs heatsink picture, easy to show or to ask

yup thats the corner shop. I was there this saturaday , there is some 8A & 6A modules on display. Ask the uncle directly its will save you time searching around the shop. I didn't see it until he pointed out to me .

Going to start your next project soon??

i am only able to acheive most 27C with my diy chiller for my 1.5ft planted shrimp tank, was thinking if i add another fan blowing the water surface, could it be able to bring down the water temp 2 or 3 degreee further?

Fan blowing i.e evapouration cooling can only cool 1-2 degrees below ambient temperature. Hence if your room temp is 29 and your chiller already cools your tank to 27C, the fans will very lightly have no effect other than cause more evapouration.

If like that then no point add another fan lo, as i am thinking fan cooling by evapouration, since already reach 27C, if more evapouration then can bring down further, so it is wrong theory.
