the 6 X 331watt TEC's running at 200watts each, are being water cooled by two TEC assemblies just like these two, they have 6 X 360mm radiators attached to them.
the 6 X 224watt TEC's running at 100watts each, are being air cooled by two TEC assemblies just like this one.
for a total of 12 TEC's providing coldness to the cold side water loop.
so it's a 3-way, on a 3-way, on a 3-way, on a 3-way, that's a total of 12 water blocks, a 240mm radiator, a CPU water block, and a video card water block, all on the same cold side water loop. I will have 3 X D5 water pumps on this loop.
EDIT: a cascade TEC setup is my dream build. to do that I would need 6 of the water cooled TEC assemblies, 18 X 331watt TEC's, 18 X 224watt TEC's and 18 X 360mm radiators. I don't see me building that any time soon.
well I decided to make a small change in my power setup, and get one more 24volt power supply. so I will have 3 X 24volt power supplies each powering 2 of the 331watt TEC's and 2 of the 12volt powering 3 of the 224watt TEC's each. so I will have a total of 5 power supplies for the TEC's. while I could do it with 4 easy I did not like having both the 24volt power supplies running at 45amps. so now there only at 30amps each, just like the 12volt are also pulling 30amps each. all the power supplies are 55 and 50amp so running them at 30amps will allow them to last longer.
well, my paint skills are not that good, so this is what I am building right now..
alright, I got my new 24volt power supply.
they have a new feature fixed voltage like the others at 26.4volts or adjustable voltage from 26 to 33volts. I am going to have to play with this just for kicks. ok, so for me to power 12 TEC's with 5 power supplies that's about $800 in just power supplies. if I add the relays and switches, with are $100 a set that's another $500. now add two PWM controllers at $60 each. we have a grand total for power alone at $1420 this is not cheap. the four TEC assemblies with TEC's are $3200. with another $1000 in costs that I am for now going to just label as extras. this comes to $5620, and about two years of playing with it, to figure out just how much TEC I really need.
ok so I have a total of 6 X power supplies 3 X 24volt at $200 each, and 3 X 12volt at $120 each but I am only using 5 of them. the 3 24volt and 2 of the 12volt. the extra 12volt power supply is from my first build as I used 3 12volt power supplies 1 for each of the 12726 TEC's I had on that build.
well here is a couple of pics of what I am working on. these are the air cooled TEC assemblies that will hold the 6 X 224watt TEC's running at 13.2volts or 100+watts each.
the expensive part to these TEC assemblies are the manifolds that I am making out of fittings. these are also what allow me to keep the flow rates up on the water loops so that they function well. .
ok, so I have been looking at a couple of 12volt to 19volt step ups as a upgrade for the 224watt TEC's.
I don't know if the air coolers can handle the 224watt TEC's at 19volts but I think it is worth trying.
ok, a few nice things I like about the chill box. for years I have water cooled my PC systems, not just the CPU and video card but the memory, and motherboard. now I don't need to water cool the memory and motherboards any more. that saves me on having to get those water blocks.
ok, so I have all of my switches and boxes for them. I also have all of the relays, 3 X 12volt and 3 X 24volt. I am still waiting on one 24volt power supply.
ok so a couple of upgrades I may add to get this build more functional. I would like to add 4 X 480mm radiators to the build a split the hot side water loop into two loops. one loop with the 6 X 360mm radiators and 3 X blocks and the other loop with the 4 X 480mm radiators and 3 X blocks. this would allow my to run the 331watt TEC's at 26.4volts without over heating the hot side water loop. the air coolers are fine now with the TEC's at 13.2 volts but I think I will need to upgrade the fan on the air cooler when I add the 19volt step up. so I will get a 3000RPM fan at the same time. again this is just to see if the air coolers can handle the 224watt TEC at 19volts. it would be nice if the air cooler upgrade works, but it will be fine if it does not.
I am changing the design of one of the water cooled TEC assemblies, I will be using 6 X of the metal water blocks, to make one of the assemblies. the other assembly is 3 X of the XSPC water blocks, and 3 X of the metal water blocks.
ok, so currently I am setting this TEC water chiller to run at it's mid capacity of 1800watts. this should be enough cooling for me to run my PC with no issues. as I have stated, I will be doing some upgrades to this system, in a effort to allow me the option, of running this water chiller at it's high end capacity of 2700watts. it would be easy for me to turn the water chiller down to 1200watts, for a new PC system running at stock speeds.
while insulating the system I have noticed that the bolts and frames on the TEC assemblies carry a lot of coldness. I have not found a good solation for this, other than insulating the bolts and frames. I have tried plastic bolts, but I do not like the constant stress the bolt is under, I feel like it will snap in a couple of years.
I think I will just use all 6 power supplies, that way I am wiring two TEC's per power supply. I don't think it will hurt the system having the 12volt power supplies pulling 20amps each.Edited by toolmaker03 - 11/19/17 at 7:59am
