Goliath Triple Cooling System

[Starkiller42]

As long as you design an efficient shroud, pull through is what I'd recommend. It's what's used in most professional systems I've seen, and if it's good enough for them, chances are it is for us too .

12 fans is gonna make for an impressively loud system; are you considering any kind of voltage/rpm control/sound dampening?

DetroitAC, thanks for the advice. That was the plan for setting up the condenser coils, but I don't understand what you mean by the fan installation.

Checkout the picture below...this is what my plan is for the installation of the fans. The picture doesn't show the aluminum shroud that will be fabricated for mounting the fans. Which air direction is better? Air being pulled through the coils or air being blown through the coils? I think it doesn't matter which direction....what do you think?

It absoultely does matter which direction you flow. What I meant is that you should put the fans on the face the way you have them and that they should pull the air through the coils (not blow). Doing it that way will be best for the temperature changes that happen in the refrigerant during the condensing process (de-superheating, condensing, subcooling). It will also be better to pull for airflow distribution.

I'd space them away from the condenser coils more and get more uniform airflow, but it kind of all depends on how you will make the shroud.

Finish brazing the plate heat exchanger fittings and the insulated housing.

Curse you! i am trying to be patient to build my system but ur give me a itch that will make me bankrupt!!
Nice work by the way.

looks excellent

Hola "Oscar", como estas mi amigo! Estoy contento que hayas entrado a mi pagina de internet.

I had a chance to do a little more work tonight. Check out the pics below...

All sealed and ready to be installed in the case.



Starting to get a little cramped

looking good!
as far as i know this will be the first high pressure chiller ever!

[Jigsaw]

This is definitely uber 1337.

[Polizei]

Is that black material delrin/acetal?

Looking very good.

[Sweeper]

The material for HX housing is made of Delrin and then, coated with a rubberized spray to seal all cracks. I also think this will be the first high pressure liquid chiller and I hope everything goes well with all connections or it could be a real disaster.

more pictures please

Wow this is a first and looks great Id be scared of high pressure system but your welds look good .hope it works well will be following progress .

increible trabajo.. de donde sos?

incredible job.. where are you from?

Hey sweeper! You can come to my house, help me with my WC build.,.. and then when we're done... we can work on the heating system for the rooms.

Excellent stuff man!

[knightwolf654]

any updates?

[Sweeper]

I've been busy with building the cooling chamber....this thing is lot of work to make air tight and insulate to maintain low temperature. But it should function as planned and look good as well. I don't think you guys have ever seen a design like this before...you will be surprised of how it is assembled! I will post pics in a few days.

I'm also working on making the high pressure liquid blocks. Below is a few pics of my design and the testing stage of how the liquid flows through the maze. I'm not sure if someone has claimed the name or not....but, I call it the "CrossFlow Block". The liquid moves very fast through the block, as you can see in the pictures.

were is a drooling smiley when you need one...
awesome work dude are you sure that top plate is thick enough to withstand the high pressure.

[n00b 0f l337]

Will that tubing hold?

[CyberDruid]

Jump up Jesus! That is amazing. What a great idea. Subscribed

Your attention to detail and build quality is impecable!

Me Gusta!

[knightwolf654]

i have a feeling he is going to use either steelbraided hose or copper pipe, no way those hoses will hold 150 psi, most rubber air hoses only hold up to 120psi

[Sweeper]

The top plate is 1/8" thick copper and will be brazed with 56% silver solder...I think it will hold The plastic tubing is just for the test setup to see flow of liquid through the maze at approxmately 15 psi. The finish tubing for the block will be made from stainless and brazed. Once all connections are completed, I will start testing under high pressures.

i'm still learning about presures so dont mind me
awesome i might have to try some of this my self. of couse it will never look this nice, i'm good with a MIG welder not with a brazing torch

[Sweeper]

Thought I would add few more pics of the liquid block...



close up view of test stage

[Noob-ftw]

Amazing work! I can't wait until this is finished. I'd also recommend getting a steel braided hose for those high pressures; I don't think normal tubing will hold.
