What size reservoir?

Psychotic · 03-24-2002, 02:15 PM

I'm gonna pick up a Du-Bro res but I'm not quite sure as to what size I should pick up. What'dya think?

6oz - 10oz will be fine I'm sure

Are there any benefits to a larger resivoire if you have the room for it? My inexperienced mind wants to beleive that a larger reservoir would give the coolant more time to cool (I know, that most likely is not the case).

What aboute reservoir design? Do some designs or materials make for "better" reservoir? ...or is the general consensus that no heat can be passively transfered while in the res, so design and materials are unimportant?

I was just asking as I was thinking about building a res with copper tubes passing through it. The plan was then to mount some push/pull fans on either side of the copper tubes. I've seen some commercial setups that use this sort of design, and I thought there might be something to it.

I'm certainly no expert, but I suppose it couldn't hurt to do as your talking about with a reservoir. It would sort of be like a second mini radiator.

I think it would need to be at least 5 gallons to provide significant cooling. I have a 1 gallon res in my setup and it does provide some protection when things go wrong. For example, my radiator fan molex connectors came loose, while I was at work

Of course, the disadvantage is that I can't put my system in the case.

I used a 12oz Dubro simply because it is a bit larger and easier to work with. Any size over 6oz should suffice.

Brad · 03-25-2002, 01:20 PM

a bigger one won't be better, the dubro tanks are plastic.

One last question on this one...

Are there any negatives to having a very large resevoire as opposed to a smaller one? I know space is typically an issue. I was just curious whether there were other issues.

I'm trying to build a 4oz res/airtrap, because I hate a cluttered sys and I have no room. But, I think the arangement of the water contributes to the cooling in a res, such as how much exposed surface area the water has. Having a tall cylinder with only a tiny circle's worth of water exposed to air at the top would probably cool worse than a tub (unless the cylinder was all metal with fins, lol). It would be rather funny taking a full 20gallon tub to a LAN now wouldn't it?

<edit> To Aristotle's latest question, a larger res with more water should have a larger heat capacity, and won't react as fast both heating up and cooling down. So a smaller amount of water will cool down faster, but also heat up faster. </edit>
