Default Project phase-change "maybe cascade"(old beginning chiller thread)

starting a new project even my old one is not finisched yet

so whats this al about.
because my previous unit wasn't that good(mounting, insulation, etc...)
i am going to make something where this is not needed (not mutch).
so what is a chiller?
its just and evaporator in a tank that chills the water and a coil (rad) thats cooling you procc.
just a watercooling with a watercooled rad(chilled water)
here is pic from a small beercooler @ school.




so i am going to make this, but smaller then.

stuff needed?
a tank to put the water in(think i am going to the local hardware store or kitchen stuff alike store.
copper: lol, just ask my teacher.
a proppelor to keep the water moving(
thats it i guess.
i've got a compressor still here and a condensor too


and this don't belong to the cooling but its needed too.
just a tank on a comprr and a condensor isn't that impressive:grum:
so mod that unit a bit.
going to apply sort of a logo on it.

going to cut that i plexi and apply it on one of the sides (w'll be lighted with ultra bright leds)

i'll update asap

tnx, i'll try to make it better then the previous
the mod part won't be the problem,
just the cooling part(i'll try my best, still have to ask my teacher) but i can make everything @ home beside the cooltechnica part

I don't think you'll need that propellor. The water won't freeze if you use anti-freeze and your pomp will make the water move already.
