Dual compressor single condenser question

[gkiing]

I have the same condenser as this, is it large eneough that I could cut one of the U bends somewhere and use it as a 2 in 1 condenser for both a cpu + gpu direct die? The two systems would not be connected, as I would physically separate the condenser into two paths for the refrigerant, but it would remain as the cube.

small compressors maybe..definatly a much larger fan

[JSU]

it depends on air flow but i dont see why not. I use the same condnesors chilly1 has on his DIY phase change and they are 1 row and work just fine. You should add push pull fans b/c of the depth of the condensor.

yes, that should work, but it is as the poster before my writes, it depends alot on the compressors you are meant to use, small compressor, small condensor.
Large compressor, large condensor.
But it seems to me that the unit you have is pretty large.
Se if you can find a pdf on it or something that tells you the wattage on it.

But, as a little "cheat", you can get the condensor "biger" that it actually is, bu using a "bad ass fan" on it.
Also, as the poster before me said.

hell, this post by me is totaly unnessasary due to the fact that the dude before me said it all already :D

The compressors will be 2x 1/4hp tecumseh low back pressure. I thought that since this condenser had 3 rows it would be ok to split up. I'll be using 2x120cfm fans in a push pull, shrouded on both sides.

Would it be easier just to do a dual evap and a single compressor/condenser? Im not sure if 1/4hp could handle that.

[Zejtan]

i belive that will be ok, the condensor will probably not have any problem with the heat load from sutsh small compressors, but, i woul probably go for a stronger fan, but hey, try it out, if it doesnt work, use larger fan/fans.

i have a few radiators like that and was thinking the same thing
cuts down on fans also

Coils are rated for a max amout of air flow. When you go above that rating the heat transfer begins to drop. So don't go to big. Or just put a speed controller on.

The reasoning is simple. Air only touches the fir 1/3-1/2 of the pipe. The faster you move the air the lower your Delta T.

toche redwold, thats a really good point, I never thought of that. Indeed if the temperature difference between the air and the coil was smaller because of a larger fan, the heat would not radiate out as fast.. So i guess you can have too big a fan in this case.
