Thermoelectric Cooler Part 19 - Radiator&Water Block

[bnewton81]

may want to switch to mineral oil esp. on the hot side. Water is highly corrosive. Fine for prototyping, but long term it is better to go with something else. Great work man. I just got my first peltier in the mail from china (lol) these things have got no end to possible uses. I could fill a notepad with inventions and I've only had the thing for hours. Great vid.

[timmytimmy64]

If you have any peltiers that you are not using give me a shout and possibly do some project item trading. Just give me a shout on my emailcan give pictures of some project specialty items... Keep inventing and building, Love it...

[TaylorHolmes]

@timmytimmy64 Nah, most of them broke or got lost over the years.

[timmytimmy64]

taylorholmes, Very nice build. Thats my kind of contraption :-)))

Would be nice to hook up with some ideas involving peltiers. They are fun to work

with and sturdy, "BUT" They are touchy (Break, Overheat, Freezup and so-on...)

I have went through so many of those things experimenting and creating that it just isn't funny. On the heat side though, You may consider slowing your pump down some. To much flow it overheats and to little flow it overheats!!! email sometime timm_1964@yahoo.com

[iluvsaphira9]

I've been following through your videos, I really like the progress you've made, even if the thing's now been scrapped ^^ I'm getting some Peltiers myself soon, so I wanna see how well I can make mine work. :3

[RamoneTalarico]

haha i have the same exact pump!

[TaylorHolmes]

@andraine28 Sorry :(

The experiment was scrapped over a year ago. It never worked well enough for me to spend more money on it.

[TaylorHolmes]

@jimmyjonlu LOL ok no problem, not sure where you're coming from with that, but I certainly don't take it as an insult. :)

[TaylorHolmes]

@jimmyjonlu no problem.

[TaylorHolmes]

@jimmyjonlu

Oh ok I see, haha.

[TaylorHolmes]

@jimmyjonlu

Why use gold? Copper and silver are BOTH better thermal conductors than gold, and they're cheaper.

[TaylorHolmes]

@jimmyjonlu

(I think) I wound up using 3/4 inch tubing (outside diameter... I forgot the inside diameter... maybe 1/2 ? I dunno). This was because of the radiator fittings I had to connect to.

By the way, I used a TON of fittings and tubings from smallparts (.) com. It's usually cheaper than buying stuff from overclocking enthusiast websites like frozenCPU (.) com .

[TaylorHolmes]

@jimmyjonlu

Glad I could help! I was led to believe the same thing by countless DIY videos that just make me think miracles could happen... not true. The great idea was that they're like refrigerators but SMALL, so they can be applied almost everywhere. Truth is, they're only about 5-10% as efficient as a real refrigerator is, they they have very limited applications.

[TaylorHolmes]

@jimmyjonlu

If I had to guess, I would say that whole closed-loop water cooling system had about half a gallon of water in it.

The water pump put out around 370 gallons per hour.

I actually had two fans; a 110 CFM and a shitty 17CFM fan.

Sorry, it's been a while, this experiment was about a year and a half ago.

[TaylorHolmes]

Well the only "formula" to speak of would be newton's law of cooling. Honestly, I'm no expert on thermodynamics.

I think the best fan I used across the radiator was 110 CFM (cubic feet per minute)

[TaylorHolmes]

It was almost as airtight as a refrigerator, the air flowing in and out of the container itself was minimal, practically negligible.

It sucked because TECs are just not what they're cracked up to be. If there's one conclusion I got out of this experiment, it's that TECs at this point are definitely NOT the heat pumps of the future or anything. They have very limited application, such as laser diode cooling, etc.

[tysipod]

Lol love deathclok and thanks for the radiator idea I've been having trouble with my units and this is for sure to help

[killuminati63]

holy shit whats that band at the end:) ?

[TaylorHolmes]

@killuminati63 Murder Train a' Commin, by Dethklok (aka, the band of Metalocalypse)

[TaylorHolmes]

@jimmyjonlu Nah man, I'm still alive and kickin. I made these videos when I had a LOT of time on my hands.  I never got it to work well enough to be proud of it.

Right now I'm back in college working on a degree in electrical engineering. Just today I spent about 10 hours studying. It's grinding my nuts, but when I'm done hopefully it will have been worth it all. thanks for watching and commenting man.

[drumsrule786]

Your using a lot of thermal paste there....

[andy232005]

shame you stopped the project I watched all of your videos last night it was a couple of hours worth I've gotta say I enjoyed it good fun :-)

[tankman35]

Also make sure the heat compound / silicone makes contact with all of surfaces. I add a digital thermostat with ntc / ptc probe to the water available from Farnell electronics in the UK. It switches a relay for on off cooliing that switches my peltier power supply on and off, simple but efective.

[tankman35]

Hi Taylor. I have built smaller water coolers using peltiers. Chiller unit using similar water cooler with peltier pumps. Check the peltier delta T or effectiveness of the pump, I used 60watt and 100watt bought on ebay for £7 uk. I wrapped copper tubing in a big coil around an aluminium 1 litre cup. I then sealed the cup into a block using builers spray expandable foam to minimise heat loss. Pump the cooled water around the cup and the water inside cools, reverse current and it heats up.

[TaylorHolmes]

No, I never got the damn thing to work good enough. I was spending too much money on it, and it had to stop. I gave it away to a physics major who wanted to make a bong out of it. I'm not kidding about that. Something to do with cooling the bong water. I never saw him after that.

[suprnovatk]

@TaylorHolmes LOL i dont know why but i beleive you!

[andy232005]

@suprnovatk what new projects are you working on? I'm working on a 8x8 rgb led matrix. Your right about the peltier units I only managed to get 3 watts out of them waste of time lol

[TaylorHolmes]

@andy232005 My next big project is simply the act of going back to college to get a degree in Electrical Engineering. If people on youtube would like to see footage of that, then something went wrong with youtube,

On a serious note, I really want to build a Cockcroft–Walton voltage multiplier to act as an ionic air purifier. You know, to capture dust and stuff. Id would be dangerous with the high voltage, but the real problem these days is money. I quit my job to go to college again....

[car776]

I learned a lot from watching these. I'm sorry that it has been 6 months since your last video. I hope you got it working at some point.

[andreaacme]

TaylorHolmes if you don't cool those TECs (and you're generating a tremendous amount of heat there with 6 of them) they are going to soon break and when that happens they could short out hence your power supply could also get compromised. Watch out! Get that radiator untangled and put some kick*ss fans on it. That will solve all your problems ;)

I'm working on a liquid-cooling project too but it has a different scope:

[paintballdoctorJosh]

Ok, a few things you should know, your fan/ducting setup is terrible and your water pump will last much longer if you put it on the cool side of the radiator.

Put a larger fan on that oil cooler and forget the ducting.

[Thetimewillgoonn]

Why dont you buy a 250mm Fan? or a car fan 12 dont know how big they are maybye 500mm will be perfect for the radiator

[kkjgg112391]

Why don't you just buy another water pump... stick a hose on it. dunk it into the water inside the cooler... then stick the other end of the hose to the coldsink...

that oughta solve your cooling miseries.... lol

[andreaacme]

Agreed with strikeagle1 that the best thing is to remove all the tape from radiator, maximize the airflow in it at all costs! Ideal would be to put 4 fans on front and 4 on back. What fin ratio and dimentions does that radiator have?

[strikeagle1]

Hey there man! :)

i've done an electronic project on thermoelectric modules...

i build a water coolent/warmer using two thermoelectric modules rated at 280w each..

i've manage to get to 5 C, which is about 40 F.

the best thing you can improve on that project you just did is remove all the tape you attached to the radiator, add some more ventilation sucking air, not blowing air (exactly like in a car) and also add a reservoir - this will take care or the bubbles in the system and also more

[strikeagle1]

...more liquid means the system will maintain lower temp. :)

i hope i helped... tell me if it improves :)

[andreaacme]

@strikeagle1

Wrong, more liquid will only increase the time it will take to stabilize to the final balancing temperature. It will maintain lower temperatures for longer time but when you get to regime it will still be the same final balancing temperature. You can't run away from the truth LOL! :)

[strikeagle1]

For longer time at the corent state, You are correct,

but i also said to put more ventilation ,that will blow more air on the radiator.

believe me, i've done it, made an electronic project on it! :)

[RamoneTalarico]

great work i like it! that water block rocks as well!

I have a few of those pumps lying around as well. got them from Aquastealth back in the day before water cooling was even really known
