cooling plate - heat exchanger (fanless water cooling)

i happend across this.. i was thinking of a design similar to this a few months ago... but im not quite sure how these are supposed to work.. do they just sit in the air? or are you supposed to attach them to your case for better cooling?...

"They are also, by far, the most cost effective as well"
at $20 each... i would hope that 2 would perform as good as a heatercore..

also.. what do you think the internal design is like?

im thinking its just one very thick channel 2 pass block

DigitalChaos · 06-13-2002, 05:06 PM

i feel i should say that i think these would perform terribly.

but i think its a cool idea.. and i wanna see what you guys have to say about it.. and maybe get some new ideas going

Cova · 06-13-2002, 05:17 PM

Kinda makes me wonder...

I know with my system idle I can turn my rad fan off (only PSU fan running, and side-panel of case open) and it radiates enough heat that my system can still run (I accidentally ran it like that for a few hours), idle temp around 45 to 50 C.

How much heat can a case dissipate into the air? If we had a long, thin WB and expoxied it to the top/bottom/other non-removable panel of the case and basically used the entire case as a large heatsink, would it be able to keep a system cool enough to run? Not looking for a giant overclock on such a system of course, but could a Duron at 700 to 1Ghz be made to run with no fans at all, just a pump moving heat from the CPU to the case.

Hmm..., might be time to look into water-cooling and silencing my server box.

DarkEdge · 06-13-2002, 05:25 PM

Its an idea. If it performed well thats great, but what about it turning nasty colors. I'm sure you could put a clear coat of some sort on it.

chazz469 · 06-13-2002, 05:53 PM

I don't get it. It's just a copper plate, right?

DarkEdge · 06-13-2002, 06:06 PM

Looks that way. I would assume the channel design is like most hd blocks. The other design I would see used is a u shape thats wide and flat. More surface area.

chazz469 · 06-13-2002, 06:24 PM

But it's only a quarter inch thick, I'm not sure that there's any channelling in there. That's what I don't get. What heat is it supposed to dissipate? Is THAT supposed to be the blok on the CPU? That ain't right!

Cyco-Dude · 06-13-2002, 06:54 PM

no, i dont think that goes on a CPU. hot water flows thru that, it gets hot and radiates heat. kinda like the thin fin tubes heater cores and radiators use.

but i agree, i think a heater core would own several of those lol

chazz469 · 06-13-2002, 07:00 PM

OK....I can imagine that. But from the picture it just looks like a .25 in. copper stock. There doesn't seem to be any barbs or any place to put barbs.

maskedgeek · 06-13-2002, 09:01 PM

if it were me and i had that attached to the top of my case, i would strap some pelts and heatsinks on that thingy, get some coolness, i bet youd get better results that way then just bare, maby some subambient if you had more watts than your cpu..... a lot more....

lol, it does have barbs, and im sure its hallow (otherwise the water wouldnt be able to flow thru it duh

).

Without any fins or active cooling how the heck is that thing supposed to dissapate heat? It says "into thin air" come on! How is it supposed to wick heat away with no air flow:shrug: I've shut my fans off and it stays cool for a little while but starts to rise up. I think eventually it would cook your system.

pompoen · 06-14-2002, 01:54 AM

like masked geek said, but some pelts on that thing and it would make a good waterchiller

Note the word "some"... That thing is so thin, I would be afraid of freezing the channels solid.

pompoen · 06-14-2002, 02:04 AM

you should use antifreeze and do some testing. I wouldnt hook up such a thing in my rig without trying it out

Convection. How is your house / appartment heated ? Are there fans on your wall-mounted radiators ? ....

I think this thing could be a great base for passive cooling. I imagine it's built like HD waterblocks, with a M or U shaped channel.
It's flat, so attaching heatsinks all over it should be easy. Should be placed outside the case and horizontally i suppose.

pompoen · 06-14-2002, 03:45 AM

i dont know if the orientation would make a differnce and still, for passive cooling, wouldnt you be better off with a heatercore.

Hmm. Me thinks you mean placed vertically.

And orientation, horisontal vs vertical, make a huge difference when it comes to cooling with only convection.

DigitalChaos · 06-14-2002, 06:43 AM

for those of you wondering about the construction of it... im not too sure BUT there is another version of it made with aluminum, brass, and copper
unless the aluminum is anodized.. i dont like that.

Quote:

The CP-482 Cooling Plate is designed for easy mount with maximum performance and scalability. The concept is simple, no fans. Complete Passive system. The plates dissipate heat into thin air... literally. They are also, by far, the most cost effective as well. Each plate is 4" x 10" x 1/4" (H x L x W) and constructed of Brass core with Copper and Aluminum Plates to increase heat transfer.

they even have some micro black ice's and generic look alikes

Yes

I just meant lean it on its side - have the inlets placed "vertically" - *not* the whole thing laying flat out. More surface exposed to fresh air coming from under. (should test it though...)
That way:

Code:

  1
+---+
|   |
|   |      2
|   | +--------+
|   | |o       |
|o o| |o       |
+---+ +--------+
^^^^^ ^^^^^^^^^^
   fresh air

Which one is best, 1 or 2 ? I'd guess 2 bur i'm not really sure

crane · 06-14-2002, 09:57 AM

Plumb one of those into the freezer compartment of that mini fridge you got just sitting there.....Matter of fact,setup a 2nd pump and just pump coolant through the heat exchanger setup in the deep freeze.
The 2nd pump would keep flow rates from diminishing on your main CPU cooling loop. Circulate that coolant through the freezer.

Cova · 06-14-2002, 11:46 AM

Set it up like in figure #2 in gmat's post above, and then slap a giant Alpha Slot-A heatsink onto each side of it but with no fans/shrouds and put it out in the open somewhere, and I bet it dissipates a fair bit of heat.

Divided · 06-14-2002, 01:50 PM

what about dropping your rad into a RES filled with coolant?

how would that be any different than just taking the rad off and using the huge res?

pompoen · 06-14-2002, 02:06 PM

you could put the radiator out, dry it and put a fan on it and go to a lan, when you get back home, loose the fan and its silent again
