    That big box in front contains the evaporator/reservoir, covered with dense foam insulation. Have I mentioned that insulation is our friend?

    Note my TECH Method "key" logo in the lower right corner.

    On top is the fill tube.

    Those are 1/2" hose fittings on the front. Right is water out. Left is water in.

    One question. How loud does that get?

    It has a big fan on it. Could be replaced with a muffin fan to make it quieter, or a fan control could be used. The compressor isn't loud at all.

    As an added bonus, it has all of the hardware for mounting it in your window, putting the noisemakers outside, with several inches of dense foam insulation in between.

    Nice job Gary!! It looks like it right off the assembly line. That will make a great toy for some lucky guy or gal.

    Have you had a chance to try it out yet?? What does the reservoir hold, about 2 gallons??
    UNDER THE ICE .com
    Phase Change Cooling

    is the remedy

    The reservoir holds one gallon. Most of what you see there is high density insulation.

    It hasn't been tested under a real load yet, since I don't have a water cooled computer, but I'm betting it will match a prommie, and cool all of the components, not just the CPU. It has been tuned for max performance at about 250 watts heat load.

    gary, i dont understand how this differs from a regular chiller

    it loosk like you just stuck the evaporator inside a resevoir

    or did you make a new evaporator? O_O

    sorry for questions ahah

    Yes and no. The original evap has been modified, added to, and given a full copper jacket. The mods worked out better than I expected.

    why would you need a full copper jacket?
    is that basically the resevoir?

    That looks very very good Gary. You are right about it having one advantage over phase change, with this you can have the gpu and cpu cooled with two water blocks in series.

    It's a shame you do not live over the road as I have twin waterblocks in series maybe there is someone on the forum who lives driveable with similar setup ?

    I'd be interested to know how flow rate alters cooling with this setup. Normally you want a pretty big gph for water, but in conjunction with something chilling the "warm" returning liquid what is the minimum time needed in the actual chiller reservoir the liquid needs to stay in to be chilled down again ?

    If you could adjust the flow rate on the pump ( or pumps in series ) you could measure temps on the fly at cpu / gpu to fine tune.

    Regards

    Andy

    It also is modded to add to heat exchange. I am not going to get into the details. Competitors will just have to buy one and cut it open to see how I did it.

    Hi Gary,

    Very nice system . Whats the taget temperature of the fluid at 250watt load? A rough guesstimate will do.

    Regards

    John.

    I would guestimate around -40C with ~250 watts load.

    150w for cpu and 100w for video card if in series. That's certainly a lot cheaper than two phase change systems.

    Is it rugged, would it travel well ?

    It is against the rules to mention price in this forum. I have quoted the price in the classified ad section.

    Yes. Since I took the pic, I mounted a black plastic disk on top of it for a better grip. Makes it easy to fill without having to remove the cover.

    That chiller has been sold to jamaljaco, and is on its way to Oregon. Jamal has promised to thoroughly test it for us.

    In the meantime, I have started building a second chiller. This one will have a smaller evap/res, which will allow me to keep the control panel. The control panel has a switch and a thermostat.

    The switch has 5 settings, OFF, LOW COOL, HIGH COOL, LOW FAN, and HIGH FAN. All will be wired together, so that it is either OFF in the OFF setting, or ON in any other setting.

    The thermostat will become a fan control, with its sensor mounted on the liquid line. This will bring the fan on only when needed. Another big plus when mounting the unit in the window.
