Insulated Box!!

Post #1 by nickolp1974 » Sun Jul 06, 2014 9:14 am

Looking for a 5-10ltr insulated box that can be used as a res for a chiller, if anyone knows of anything suitable please let me know,
Thanks

Looking around its likely to be a cool box, any plumbers on here know what i need, as in 2 bulkhead fittings that will convert too G1/4 female threads???

I take it you'll be drilling the cool box to put something threaded in?

Yes and PC bulkhead fittings won't be long enough!

In saying that am I having a blonde moment could I just drill the lid and just sit both pipes in the fluid????

Plan was PC on desk, big res on shelf above and chiller below PC, would of thought this would help the pumps(2x18wDDC pwm) so ideally I would like one port at the bottom.

Through the lid means you'll be fighting gravity to keep flow.

Do you have an approximate length required? I'll have a look though my pipe fitting stuff at work, see if I have some longer 1/4 bspp barrels.

No idea on width at present, would imagine a cool box wall to be 3/4-1"??

Around that I would have thought. IF it is completely solid walled, I'd tap the actual box.

Hi!

I have been using a chiller for quite some time now, the only reservoir I use is a small Phobya Balancer 150.

So I was wondering why you want to use a reservoir that big?

Just curious about that!

Takes more heat energy to warm up a larger volume of water ='ing better cooling.
Stability of cooling temps is improved and that makes for the ability to go higher for longer periods of time, esp useful for longer benchies.

With a chiller you do not want to use a large reservoir. Bones you are forgetting one important detail here. The chiller is an active cooler, so it will be removing between 500W to 1650W depending which model of chiller you are using each minute. You want as small a volume of water to cycle through so that the maximum effectiveness of the work the chiller does is possible. To large a volume and you dilute the effect of the chiller based on the guys who I know run chillers and the core maths behind the principle.

With a Ice Bucket there is an active chiller too, the ice cubes. But that is only replenished when you physically add more. But the principle remains the same. Unlike a chiller unit you will need more volume (not huge amounts) to offset the thermal dump into the water reservoir. Once the ratio of ice to water reaches a tipping point the effectiveness of the active cooling reduces exponentially and you need to redress that urgently.

Yep, I forgot about that. :?
Been running a setup with an open res stuffed with ice and in that case thats the best way I've found for it to work. I thought he was referring to a setup not unlike a slushbox with the rad immersed in ice water.

Good explanation HiViz!

Before I started to use a chillrer I have read loads of technical manuals / theory from mainly big airconditioning and industrial chilling compagnies. I wanted to know how it works, what the pro's and cons where and what tot expect from the performance.

Why chill?
In general a normal watercooling setup reaches its maximal performance capacity when: The loop has a sufficient pump, enough radiators to disapate the heat generated by the components that have a cooling block mounted. And the Fans used on the radiators have to provide sufficient airflow.

Example: 1x CPU 4770k, 2x r9 290x .

Lets assume that the CPU maximal draws 100watt, and the gpu's each 300 Watt. So in total you need a cooling solution that dissapates 700 watts. For arguments sake we assume that 2 x 360 mm radiators will do this easily.

The best that cooling solution ever is going to achieve = lowering the temperature of the cooling liquid to the temperature in your room (=ambient temperature).

No matter how much extra pumps, radiators, fans or whatever you add tot the loop, it wil never go lower than the ambient tenperature.. Since the fans that blow the heat from the radiator use air from your room, thus ambient = lowest point of the cooling liquid and in theory the lowest temperature of the watercooled components.

If you reach the maximum capacity of the cooling solution when putting your system under very heavy load @ highest possible frequency: then considering other cooling solutions come into play. Like liquid nitrogen, phase changers, tec plates, helium and also the use of a chiller.

I am still finetuning my setup and will share my experiences, maybe create a kind of guide/how to bench with a chiller.

The biggest challenge is to get the chiller running at its lowest temperature but being able to do so without frying your system.

Yes, indeed there is a real big danger to get short circuits because running very cold liquid causes condensation = the forming off water droplets.

This takes place on every surface of parts that have cold fluid on one side and contact with (much warmer) ambient temps on the otherside.

In a standard watercooling setup this practically goes for every part in the loop. The higher the thermal conductivity off a material, the higher the amount of condensation. If you do not take this natural phenomenon into account you will most certainly fry your system within 30 minutes.

To be able to understand how the science of condensation works, I had to dive back into (for me almost forgotten) the science behind this.

Tot be continued (in its own thread) ..

Looking forward to your guide on chillers Henk. I did a LN2 benching course for n00b a few years ago in Cambridge at the Riverside Pub. 16 people attended over the course of that weekend, it was a total blast. I think I may still have copies of some of the notes I used for the morning lectures. :)

If so will post them up.

Thanks Dagmar! I am very interested in those notes! Gradually building a knowledge base is great and notes like that are golden! :D

I have 2 chillers on the way one is 1650w and one is 3300watt gonna mod them with ranco controllers etc-111000-000. :mrgreen:
I will have 4 d5 pumps (2 in parrarell for flow) in one place before chillers and 2 after in parrarell 2 keep pressure upp for blocks.
And fluid gonna be a mixture of alcohol and water for (-20 temps hopefully).
Will post result of the setup here later and on ocuk.

Btw on monday i get 5960x,gskill,rampage5 and phase :twisted:
