Very low flow block

Kaz2020 · 03-05-2003, 08:35 PM

Hey guys, I have a Koolance system (yeah, yeah I got $100 off so I couldn't say no) And I want to add a bit of cooling capacity to my system. I think the pumps (but I'm not 100% sure) produce about 20 GPH and I want to know what kind of block I could make that would actually work. Also if it matters I am stuck with 1/4" tubing. I have access to Dremels, a CNC mill, and a drill press.

Thanks for any and all of the help I get.

Well, if you have access to cnc, I would say make you a nice block and just replace the pump in your system....Should get a hefty boost in cooling just getting rid of that ridiculous excuse of a block.

Koolance, at its introduction, was a very nice performing system,components, ect. But has went to $hit in the recent year or so.

I wouldnt even waste any time trying to make a good performing system out of existing Koolance components, and just rebuild a system from the ground up.

Whatever you decide to do, good luck!

A side note......once you start making blocks with that cnc, you will be hooked.....believe me!

The problems are not so much the block. You have a whole system designed around low flow from the pump the the rad (1/4" I belive). The system is designed to work it's best the way it is. Changing something is not going to help to much without changing it all.

step one, get rid of the small Radiator, and replace it with something like a heater core.....

1/4" tubing, properly applied to a good radiator and the right block design even with a small pump, will knock the sox off of most commercial servings

20gph though? I used 1/4" tuning quite a bit with a 170gph pump with good results, but 20gph? I don't think so. That water has to be bearly moving.

but remember.... at such low flow rates the diameter of the tubing renders much less virtual flow resistance than it would for, say that 170 Gph.

or to put it in another way.... the effects the 1/4" tubing has on the 170 GPH pump's performance, is much more than on the 20 Gph pump. Granted, the 170'er might FLOW more, but it's going to work a lot harder, thus the amount of heat added per GPH gained, might actually make it loose against the 20GPH when all is said and done...

then there is my favorite saying......" it's not how much you flow, it's what you do with your flow...."

I don't want people to think I'm anti high flow.... on the contrary.... am the one that sticks two 400GPH pumps side by side into a space smaller than what's needed to U-turn a nanobot.... well almost

you know like this Picture.

Yeah 20GPH isn't (I think) possible. I've used a 65GPH pump, a bucket & a maze2, and it was a dribble. Maybe 1.5ft tubing.
