Some thoughs on DIY water cooler (part 1)

Hi folks,

Many of you guys out there have considered to buy a chiller for your marine fish & reefs. I guess especially the RT keeper. But often the equipment cost an arm or a leg.

I myself only keeping a FOT but still found if I can add a water cooler for my fish can do more good than harm during summer days.

Due to my job nature and dealing with Thermo electric cooler business for years and I come across with the semi-coductor called "Peltier Element cooling module" (see enclosed photos for Peltier element and cooling module assembly ) and found it can be converted for the use as water cooler. Infact this is not something new but there are few water chiller product is already out in the U.S. market for selling using the same type of technology, but the prices are still high. This type of chiller can cool down the water temperature within a limited volume. I would be thinking is good for most Hong Kong fish keeper since we usually has small tank like myself and believed it can be use in the tank with less than 200L. As for the cooling performance, I expected it can lower 5 to 6 degree C than surrounding temperature within the 200L. Certianly, the volume of the water can also affected the cooling performance too. Although, I have not conducting any test on my above theory. But soon, I will attempt to draft a construction drawing and make a sample for testing in DIY water cooler (part 2).

Picture fo the cooling module assembly (Peltier module + thermo grease + Aluminium heatsink and aluminium block )for heat transfer. See below pics.

水域有人用$2XX 整左個用"至泠片" 的，for small tank, is that the one u are talking?

seems TECO MARCO serie chiller also using this, and those credit card gift give the 小型電冰箱 (retail $199) also using this stuffs.

小心... 一係就一面冷一面超熱..
如果散熱一失敗就燒...最後兩邊都熱..
咁同煲水冇分別... 所以要做足保護線路...
同個用電量好得人驚...

iceprobe成set野我之前同美國佬傾過... 如果全套連日立電子控溫器要成99+50US... 但未計運費... 我懶搵番舊post.. 我應有提過下

Catlee,

I have seem something similar in FS, but they are no good. Using the T.E. module is not just adding the peltier element and stick with the heatsink + fan that simiple. The size of the heatsink is actually calculate by measurement. The r.p.m. of the fan is also need to be measure precisely to achieve good performance. Strong fan does not give good performance either. I am thinking about it right now and will take some time to share with you guys. Whether it is worth or not. I don't know yet. The the whole unit if DIY can cost below HK$100. If the power is no good for fish tank size than add more unit till the tank's temperature is satuated.

KK,

U are right, one side is very hot while other side is cold. The whole cooling unit can add a thermo fuse (auto shut down) to prevent it over heating ga ma. The worst thing is that the unit consume high power (more for yr electric bill) but the good side is very quite and no feon gas leakage or filling required like those compressor chiller most ppl using.

係呀, 好多魚友都係細缸實o岩用.

之前別魚網有網友做完成功run 左幾日最後都失敗收場, 可能佢冇咁detail 有fuse 同計埋風扇流量. 如你成功, 快快post 上來, 愛黎俾QT 用都好啦, 魚病都病得開心d.

想問, 咁一塊 probe 功率幾大?

Hey guys, I am back. Some so busy in the past months. Finally, I had the construction drawings lined up and special thanks for KK to help me out in converting the file into jpg format.
