Lost In The Fog

Sounds like your peltiers are the wrong temp range or you installed them backwards haha

Some are made for cooling air, they put them in some small wine coolers and stuff. Most are made for cooling a couple components inside a build so they really don't provide any sensible cooling until the parts are actually hot enough.

Refrigeration, it's magic!

That much I know. :)

They are all connected right and the cold side is pointing at the heat exchange blocks. Think they overheat them selves someway. Read that if they do they start just to produce heat both ways. Will keep experimenting...
 
Second test has commenced. I have added the radiator in a first step of lowering the water temp. Next up is the first peltier heat exchange I used in a test. The amp draw from that is 3,5A. So it's cooling effect is 42W. This element comes from a car chiller box. So far it's cooling the water instead of heating it. I think I was scammed on those other cheap ass peltiers from China. Their second grade or third grade semiconductors.

Test is still running and water temps are stable at 40C. You can easily touch the lights. Been looking at some more quality peltiers and think I will order a 14,5V unit I=9,6A @P= 85,2W. That would probably keep the water chilled for three lights. Now it feels like I'm getting somewhere.

Quality parts can't always be found in dumpsters!

I know shed! But these parts that didn't hold up was new... But I'm happy it turned out good anyway. It's going to be really exciting to what the more power full module can do with temps. Found pipe temp sensors with 1/4" threading for the output on the cooling blocks so I can monitor the heat from the lights.

This weekend have been fantastic. My x have been at her daughter so it's just been me and my dog, and a lot of tinkering with Poseidon. :ganjamon:

Lawyers?
 
I hope so too Shed.

Yeah, today was not so good. Busted the smaller pump up but manage to glue it together once more. Busted the only working peltier beyond repair... they are really delicate with their ceramic plates. But I got conformation on my 85W today so it should be here tomorrow. Thank god for UPS. So this project should still be on track. :)
