Refrigerant Cooled PC Options

[Guest_I2aMpAnT_*]

as some of you may know, I take HVACR in my school, we use refrigerants that regular people may call "Freon", basically there are 4 main parts to a refrigeration system, a compressor that pumps the refrigerant throughout the system, an evaporator which absorbs heat, the condenser that rejects heat and the metering device which meters the flow of refrigerant. the best comparison of refrigerant is a sponge, it literally sucks the heat up like a sponge. in order to graduate from Cape Cod Tech which I attend, in your senior year you have to create an invention and fabricate it, because my major is HVACR I will probably "liquid cool" my computer....this picture is not mine but this is what it would look like....




I would be doing something like this but MUCH better, neater and just more domination, this "AutoCascade" overclocks a Pentium D 830 t0 5.3GHz
Another picture is a team that overclocked a Pentium 4 to 8GHz









DAMN...Imagine a Core 2 Quad Running at 8GHz

good stuff. Fab something up that looks good and doesn't leak and I'll buy it from you.

lol if you order the parts, I can build it at school...this stuff is VERY expensive tho I warn you, and copper and refrigerant prices are up like CRAZY!!!


and umm... you know this isn't going to be very quiet in any way?...maybe the temperatures are worth it tho.... ( -50F )

good job on the temps... abit messy for my taste.

yes indeed very messy and everything and also very loud and expensive...but can you imagine being able to overclock a Core 2 Quad to 8GHz???????????

[Maddogg_SLI]

yeah you cant deny the ghz ur gettin out of it. i would love to do something like that if i had the space.

it's not that big of a setup...just loud, and expensive..I could definately make the tubing go inside the computer and onto the CPU, GPUs, wahtever you want cooled....

Erm, correct me if I'm wrong, but isn't this just a crude, DIY phase change concept? Phase change coolers use compressers, evaporators, and condensers just like you explained, only that they've been specially designed for use in computers (pre-installed thermal insulation, CPU heaters and whatnot.) A tad expensive, though.

If you do manage to make it though, kudos to you indeed. That's quite a feat.

if you read my small explanation I wouldn't call this phase change...yes the refrigerant is in different forms of matter in between the basic parts of the system so call it whatever you want...but the performance increase is pretty obvious....8GHz

Exitios i think your exactly right it is basically the same thing. if seen pictures of the inside of that black box. and its basically a refrigerator with some balls

A/c for homes and cars refrigerators all the same just use different refrigerants

1. he's not right
2. neither are you
3. don't pretend you know something about HVACR when you don't

[Maddogg_SLI]

wow dont get mad here.

but wat u basically explained in your first paragraph... shows that it is an A/C system.
all hvacr is an air conditioning system.

I aint gettin mad...and you're wrong. That is a basic refrigeration system. AC's are a bit different
HVACR is Heating Ventilation Air Conditioning and Refrigeration

what?

[Exitios]

Fine. They could be the same thing, they may not, but the principles and construction are the same. They both use refrigerants, compressors, condensers, evaporators, capillary tubes and so on to compress and evaporate a liquid coolant to achieve sub-ambient temperatures. If you ask me, they're the same thing, your version is just on a larger and ridiculously complicated scale. You can have a V8 engine and a V8 with a turbo-charger, but they're still engines even if they may perform differently.

that's pretty much exactly what this is...it's a refrigeration system tho..it has no other name

My friend�s dad works on refrigerators for a living. When I built him a computer, we were working on putting in the liquid cooling and his dad (kind of a dork) decided to jump in and make us a miniature fridge to chill the water. I told him about phase change cooling and his dad and him split the cost to buy one. His dad just wanted it to tear it apart and see how it works, but anyways...

What we found out is that phase change cooling is not EXACTLY a fridge but works very much on the same exact concept (I knew how fridges worked but didn�t know that phase change cooling was practically the same thing). Basically what you will be making is a phase change cooler. The above pics shows a rather LARGE phase change cooler as those made for computers are designed to fit in one. Due to the large scale, it most likely works a bit better than the phase change cooling on the market.

Here is how it works: (I will try to break this down for those not thermodynamically inclined)

A compressor compresses a gas (usually a refrigerant, wont go into that) and causes collisions between the atoms to increase (compare to 4 guys jumping around a football stadium vs 4 guys jumping around "compressed" into a closet...). With each collision, heat is generated, thus the gas temp increases. So if you started out with a temp of 30C in a room of 30C, now your gas is compressed and at the temp of, lets say, 40C (adding 10C by compressing). Now we pass this gas through a radiator or condenser where it is exposed to the room temp and heat is given off. So the gas is now, let�s say, 32C and a liquid (hence the �Phase Change� title). Once decompress, the liquid loses the 10C it was given when compressed. And so it�s now at 22C. In refrigerators this will be used to directly cool the air in the fridge or cool the air pumped into it yet in phase change cooling, it is sent directly to the CPU.

Now for all those physics geeks and such, I know I left out a lot of theory and what not but I was trying to make it simple.

I hope you're describing something other than a refrigeration cycle cuz if not then you're way the hell out in left field buddy

Oh snap!! That’s right, this isn’t the nvidia forum full of users with a less than average understanding of complex thermodynamics!! Stupid me for not explaining it on your scale of education (high school is it? Why don’t you finish dropping your pair before acting like the Einstein re-incarnate). Anyways... how a fridge works (for the smart ppl like I2aMpAnT)

Basically the same as I said but when the gas goes through the condenser it becomes a liquid under high pressure and temps (high temps relative to its boiling point but since the boiling point of a liquid increases with pressure, it remains a liquid). When the liquid is released into a non pressured chamber, it immediately starts to boil and thus drops to its boiling point (which is why refrigerants usually have low boiling points).

Again I apologize for assuming there were some people on this forum with little to no understanding of physics and thermodynamics.
