Chilled water (56K beware)

so i should go w/ a 40/60 mix since that freezes at -42C
also what do u do when u are handling methanol

also how hard is it to find ethanol

and runmc how did u seal your res

[jamaljaco]

Sexy rig! nice really nice,.

[runmc]

The reservoir was soldered together. Then I sealed it with silicone on all the joints.
I insulated it with three layers of 3/4 inch foam.

I used pure denatured alcohol. It is highly flammable and when it burns, you can't see the flame. Never breath the fumes. It can blind you, for sure.

After I had my chiller up and running, I sealed the top as well as possible with Armaflex.

Well, I had a bunch of ethanol @ last nights new years celebration. You can get that at any local liquer store.
the methanol in the can I posted earlier can be found where ever paint suplies are sold.

[jamaljaco]

yea ,Methanol , were latex gloves, gogles,don't drink it and don't smoke.

if i got some plexi glass and made a res from that and sealed it w/ slicone would that keep the fumes of the methanol enclosed
also when i fill my res should i do it outside

ok< things to consider will your sealant hold up to the temp and the methanol? How much trouble to insilate it?way to much trouble just get another small cooler do all your plumbing from the top.

...ummm..congrats on the frostiness inside your res...good job on getting it going. Couple of observations on my part though,,the fans look like they are facing the wrong way, they need to blow through the condensor to help dissipate the heat so that it can turn back into a liquid.

Actually, airflow through a condenser can be either push through or pull through. Pull through is slightly more efficient, thus most condensers are designed for pull through.

Did you see my res in the chiller/ac unit sticky try something like that your evap coil can be molded to fit a different container if need be.

I filled my res in the house. just make sure your not around any open flame. If the fumes get to heavy just open a window and leave the room ,its really not that bad just use some common sense

[water_cooler 20]

would i have to make the res air tight

Ok, thanks for the correction Gary. But, wouldnt he still need his condensor to be in a more upright position, or at least not laying flat in order to get more air to pull through?

Gas line anti-freeze is pure methanol and is sold everywhere.

As much as you can . you dont want all your goodies to excape and poison you and if you smoke well....

RUNMC: Very Nice Rig! How come your not using atm?

In regards to the danger of methynol, of course it can kill you and make you go blind,,,it happens to a few alcoholics or stupid teens every year from drinking Wood-Alcohol (methynol),,,so NEVER drink it! LOL

In regards to using hydrogen peroxide in your system,,,what about the bubbles in it? Or does that only happen when you put it on a cut?

EDIT: I know, I need to read more...........

The hot vapor should enter the top, and there needs to be airflow. That type of condenser, called a "static" condenser is designed to be used without a fan, but is normally in an upright position. Since hot air rises, and the tubes are spread out, there is enough natural airflow to dissipate the heat. The center portion forms a chimney of sorts.

In this case, if its a combination that gets rid of the heat, then its okay. But if it were stood upright, as per its original design, then it wouldn't need the fans.

I'm afraid I gave Runmc some bad advice as regards cap tube sizing on his chiller, which is probably why he isn't using it. I am also learning here.

I didn't say that.

Changing the captube was a good learning experience for me. I quit using the chiller, because I moved on to direct-die cooling.

Gary gives the best advice, ever. He is a wonderful teacher, with tons of patience. Learning anything from Gary is a pleasure.

just get two 1gallon jugs one you get from the local gas station or auto parts store full of WW fluid, the other jug empty.

fill jug #2 -- 1/2 full and then fill both up with your choice of alcohol or methanol.

USE a funnel and open methanol, hold breath , pour , put cap back on both jug and can. shake well, DONE DEAL.

and do this outside

[water_cooler 20]

today i'm going to home depot to pick up some methanol
should i use the one home depot sells or gas line antifreeze

i'm also going to pick up some acrylglass to and put it on top of my res with closed cell foam on the edges than drill screws into it
and i think that will get me airtight

[jamaljaco]

If your reffering to the S-L-X denatured alcohol at home depot it is the same stuff (methanol) as the gas line antifreeze.

[water_cooler 20]

thanks for clearing that up i though they were differnt

[runmc]

The windsheild wiper fluid works good untill you get down to it's advertised freezing point, plus it's alot cheaper.

If your coolant isn't freezing up, I would stick with WWF for now.

When you get your rig perfected to a point where the WWF is freezing, you should change to something different.

Gas line anti-freeze and the denatured alcohol are two good coolants I know of. The denatured alcohol is a ethanol denatured with methanol. You could probably run a fuel dragster with it. It is very flammable. It is very dangerous. I would suggest the WWF untill you have everything sealed and figured out.

As I recall the denatured alcohol was $7.00 a gal. - not to cheap. I would be careful watering it down or you'll wind up having your mix freeze.

Fill your reservoir up, so that all of the evaporator(copper coil) is submerged in the coolant.

As you can see in my picture, I had the return coolant spraying down accross the entire evap. That let the pump pull the coolant down accross the coil and back to the water block.(this idea was one bowman gave me) You get a more evenly distributed coolant flow that way.
