cooling plate - heat exchanger (fanless water cooling) - Page 2

gmat · 06-14-2002, 02:22 PM

Wrong. For 2 reasons:
1 - a res acts only like a "capacitor". ie unless the res has copper walls with kinda heatsinks, it will *not* disspipate any heat. And if it does, heh it's a rad...
2 - This *is* a rad. I like the idea of it being flat so i can stick as many heatsinks as i want. Adding an interface between it and air (ie rad -> water -> air) is a bad idea. Any interface means heat resistance. Heat losses mean less efficiency.

The "idea" of putting a rad in the fridge is old and beaten. Please forget it. (scan this forum youll know why)

lmao... wtf.. ok i guess ill give you that one =)

generally and realistically.. YES
but if the res is HUGE then the walls of it will loose the heat over time.

Yeah but the coolant in which you put the rad, will heat up, until it matches the coolant from the rig, then the whole thing starts heating up, and reaches the balance point where the water in the tank can dissipate its heat in the air as fast as the CPU puts it in the rig coolant.

It's a bad idea. It'll work good at first, but it gets progressively worse.

gmat · 06-14-2002, 02:54 PM

Exactly. In short that's like insulating the rad.
Just let it dissipate heat into the room.

Ah also i'd want to be able to lift the PC, not to mention taking it to LAN parties...
BladeRunner's config use a Huge (tm) res buried deep into the ground. Actually the ground takes the heat away.
Apart from this special case, you're better off with a true rad. It will be far more efficient than a res spreading that heat away...

hey it was just a thought that crossed my mind

there are people who succesfully cool their cpu down with only a 100L reservoir, just search the web I'm not in the modd for it right now

gmat · 06-14-2002, 03:21 PM

Hehe i dont even imagine hauling a 100L res to a LAN party

And i still cant imagine a 100L res sitting in my cramped apartment

(unless its one of those Vortex thingies)

thats were my radiator in reservoir thought comes into the picture

bigben2k · 06-14-2002, 03:35 PM

then just use quick-connects, and hook up your rig to the 100L tank directly. Use a valve to switch from "internal rad" to "external source of cooling".

gmat · 06-14-2002, 03:42 PM

I'm looking into "internal" passive cooling... that way no valve no hulkean tank no fan no noise no hassle.
"internal" is an abuse of course, all passive cooling elements are to be placed "outside". I'm still running sketches in pro/engineer but once i'll get something in shape i'll post it.

DigitalChaos · 06-14-2002, 04:18 PM

reverse thread jack (even though i helped jack it)

ok so back to the cooling plate thing... i just bought one... i have a feeling the fittings are also 1/4" which sucks... but i bought it mainly cause i want to see how they are designed and make my own custom.

gmat · 06-14-2002, 04:55 PM

Mmhhh 1/4" sucks indeed. Too bad, this looked quite good at first glance. The same thing with 1/2" would rock (and a whole bunch of profiled sinks attached to it hehe)
Still i like the flat surface it's ready to get modded

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.

I have gas forced heat. I don't have radiators their not efficient enough. My heat is forced with fans
