[Pimpsho]

ok well i didnt get to make it to home depot to pick up the pipe benders.... but if u guys maybe could post a good set of them then ill have something to look for....thanks

[Gary Lloyd]

Here's what they look like:

Scroll down to the 3 in 1 benders. That's what you need. If you shop around, you can find them a lot cheaper.

You will be amazed at how easy it makes the bending.

[mrnuke]

Gary, can you please specify what you mean my coiling something up to make it more efficent again. I am a vapor n00b

[Gary Lloyd]

mrnuke... What I was suggesting is that you put the evaporator in the cooler diagonally, so that the coolant flows through it instead of around it.

[mrnuke]

what is the difference, by having it in diagonally is that better flow for the freon?

[Gary Lloyd]

No, for the coolant (anti-freeze mixture).

If you pump the coolant in on one side of the evaporator, and out on the other side of the evaporator, then it has to go through the evaporator and get colder.

[Gary Lloyd]

I'm not sure if I am making this clear. The evaporator should be vertical, as it is now, but just turn it a little so the ends are against the sides of the cooler.

hes just saying so the coolant has to be forced through the fins of the evap it has nothing todo with the freon or r-22... hes just saying if the liquid goes through the evap fins it has a chance to get a lil colder or stay at a cooler temp under load...

Good work there guys..... This thread is excellent for someone who's just starting to make a chiller...... one question though and sorry if its off topic, H0w come there arent many who uses windshield wiper fluid, ive seen ones that are good to -45c and its alot cheaper than antifreeze..... also isnt alcohol a lil dangerous especialy if your pump is submerge in it? thanks....

[Gary Lloyd]

Windshield washer fluid is methanol alcohol mixed with water. It can be strengthened, if needed, with gas line anti-freeze, which is pure methanol. Many of the chillers in this forum are using this and it seems to work very well. I take it the concern here is the effects that this may have on the aluminum fins and/or the steel endplates. I know very little about the subject, so I'm just sitting back and watching.

Some one should try d-Limonene

GREAT THREAD! Keep it going!

I've been researching into doing one myself so this has been great to follow.

[mrnuke]

I got my new danner mag 5! also, gary, in the picture of the evap, do you want it diagnol side to side like that in the red or up and down (elavation) for the way you were trying to explain to me?

[Gary Lloyd]

Yes, side to side just as in the red line. This divides the cooler into two triangular shaped compartments. If you pump your coolant into one of those compartments and out of the other, then the coolant is forced to flow through the evaporator.

[mrnuke]

thanks a lot, glad we could clear that up

[Pimpsho]

well sorry to say but all the good stuff is gone....i was almost done and i had it in the cooler when i here this PSSSTTTT and white stuff goins everywhere and now all i have is an empty ac unit....ill post a pic of where it broke...

[Pimpsho]

well gary was right right next to the brazing
well now it looks like i get to tweak it right? is there any thing u guys could ponder up todo that would make this thing chill better then b4? im up for ne ideas or would u guys just say get it all setup and bend it all up to fit inside the cooler then have someone fix the leak then fill it up again? how much for a refill of r-22 or whatever i could put in it for better temps without having to do a big overhaul on the hole thing...

[Pimpsho]

[Pimpsho]

this is where i was at basically finished....

[mrnuke]

don't get down guys, i still got mine and i'll definently post pics of it all. This weekend i'm gonna work on it and i'll have the pics up soon there after!

[Gary Lloyd]

Ouch. This is where you start spending money, whichever way you go. You need to decide whether you want to get all the tools needed to fix it or to have someone do it for you. Either way, it is going to be expensive. Another idea would be to get another A/C and start over. No good choices.

[Pimpsho]

really how much to just patch it up and fill it? over 100 u think?
