Building reservoirs

[remember300]

Im looking at trialing something to cool the liquid in the res but id have to build my own res.

My idea behind it is that if the liquid is cooler than ambient before the cpu gets it the cooler liquid its self will help to drop the overall temps, so water cooled systems can technically go below ambient when ticking over?

before you say imposibru! id be using a piezo electric heat pump transfer system.
sound like a good idea?

Yep, do it! Reservoirs are quite easy to build if you can cut acrylic in straight lines. For example, cutting tubes with a bandsaw to get the cut edges as straight as possible. You then clean the faces to be joined with fine wet and dry paper and solvent weld the sections together.

ah good i need to put metal plates in there too which will be fun lol, next question is any good waterproof thermal compounds? and btw this is already working to cool my beers with out a fridge

using an old fm2 cooler running off 4 AA the can has condensation so its getting cool but my god the heat sink is warm lol

 

[Davva2004]

If you lap both surfaces the coolant itself will act as a TIM between heat exchanger and the heatpipes.

im not making heat pipes, im sort of making layers where the liquid sits and chills in stages as it flows down to the pump and the the chilled liquid goes through as normal then into a rad to bring the temps down a little then the res chills its further

imagine a with a few sections with aluminum heat plates that will chill the floor area kinda the opposite of the cpu top lol

here is a pic just showing in a simple way its working to cool choc down lol

If you get below ambient wouldn't you have to worry about condensation?

 

[remember300]

yeah a little but it does mean cpus could be pushed a little harder. with out the need for phase change or ln2 to go below ambient, plus could always use similar sleeving tp phase changing kits.

I built my own reservoir a few years back and it worked well, it's the pic in my avatar. As for going below ambient - you will get condensation depending on the delta and humidity.

This may be a noob question but i don't see a technical problem but rather an efficiency problem. This setup would have multiple interfaces, rely on a separate cooler to cool the piezo element, risk freezing the water and having ice in the loop, having the water heat up from ambient after it leaves the reservoir?

I have a proper chiller here but have not used it yet as I don't want to insulate everything to avoid condensation.

When I do use it I will aim for ambient or maybe a couple of degrees below but no lower.

Think of it this way - take a cold can of beer or coke (whatever your poison) straight from the fridge and wipe it so that it's bone dry. Place that can in to your computer and within miniutes you'll have dangerous condensation present on the surface of the can.

That can was previously bone dry and only cooled to about 3C - 5C. You're talking of a cooling system powerful enough to freeze the coolant (so that'll be -40C according to my ANTI-freeze coolant), and that system will need some serious cooling of it's own as you know with piezo elements.

As Kaapstad mentions, a proper chiller can be used are are quite good, but care must be taken. A bit like this guy:

not to mention the added power comsumption for powering your TEC and the noise associated for additional fans to cool the hot side of it. The theory is the cooler you keep the hot side the colder you can keep the cold side. I've done TEC cooling before and while it was fun its just not practical for the additional 50-100mhz you may get. Plus the added expense of condensation proofing the board cpu tubing for the liquid yadda yadda.

 

[remember300]

I was not gonna supper chill it but it was just a thought one of many I have when reading forums and stuck at work looking at the electronics kits.

I know about the condensation issues but was just having a little thought about pushing cpus again and temps are always the issue.

It'd be a neat way of replacing a radiator if you could get it to a stage that it only cools as much as a radiator would do, you could have some very neat watercooled SFF systems! Best thing to do is just build it and give it a go with some old hardware dude
