I was fooling around with TEM chilling for my nano marine tank and I built a

http://arofanatics.com/members/bezz/...nk/image08.jpg

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.

Step 1 ....
Step 2 ....

step 1 : Read up and understand what is TEM. Then calculated the heatload of your tank. from the graph in my first posting.

step 2 : Look at other's design. If you want perharps you can come up with your own design. Get the parts as you mention above and assemble your unit.

step 3 : ......


thermal grease is a must . Its a help to conduct the heat from the TEM to the heat sink.

xtrekker & Arolee999 ,
Bros, can u tell me what type of heatsink u use for the diy chiller to dissipate the TEM heat? From ur diy pictures, it doesn't look like normal aluminium heatsink, where to buy? Price?
Thanks...

My heatsink is from foxcon .. ITs a heatsink for server. This type is heatsink is know as "Forced Convection" because it uses a fan to increase convection cooling . Got it from level 3 at SLT. First shop on your right when you comeup from the escalator. about $12 -$15 . try to bargain .

cheers

foxcon is the shop name or the heatsink brand?
level 3 is mean the most top floor rite? better can know the shop name of shop lot.
i feel that my aluminium heatsink not good enough to conduct the heat from the TEM, so the cold plate no cool enough because the TEM delta temp is 68C, if the cooler the heat side, then the cooler the cold plate, rite?

Hi,
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. :D
