This cooling tech sounds exactly like the radiator in my car.
However, radiators in your car are also effective due to a constant airflow over them as they are moving. Datacenters don’t move, so what will help that transfer?
Being bigger. They don't move so they can be huge.
Is it reduced 100% or 1200%?
This article fails to mention (I presume, after skimming it) that all these data centers aren’t using water because it is magically better suited for this job, it’s just cheap and abundant.
This “new cooling design” doesn’t mean shit when it doesn’t address the reason data centers are using so much water
They kinda do, they say that, because the coolant is so efficient at transferring energy, a data center will not need evaporative cooling.
It would be very interesting to know what the upper limit of air temperature would be.
They already don't need evaporative cooling. They just don't want to pay for closed loop systems because they're more expensive than evaporative cooling.
The solution exists, it's just not required so no one is paying to do it when they don't have to.
Existing systems rely on air to pass heat to a radiator, which then relays heat to the ambient air outside. In order to keep temperatures inside the data centre at sane levels, the cooling water needs to be below ambient temperature, which can be done with either chillers or evaporative cooling. Running a chiller takes a lot of electricity to say the least.
By exchanging heat between the chip and the cooling water directly, it seems they're claiming they can just have a heat exchanger with no chiller or evaporative cooling required. Which is probably true, it's why over clocked gaming PCs are often water cooled.
Again, they’re not using water for its properties. Heat transfer efficiency is low on the list of priorities. Cost, both upfront and running, is the deciding factor
Surely you must realise heat transfer efficiency and cost are closely linked, right? You haven't told us anything we don't already know. Of course this is about saving money, that's already obvious.
Who’s us? I didn’t struggle understanding what they said at all
I'm not sure what argument or point you're trying to make here. Why do you think they're using water, exactly? And surely you must realise how efficiency and cost are linked?
I don’t know how to be any clearer.
LOW COST > HIGH COST.
It’s money. The goal is to save as much money as possible. Businesses, corporations, contractors, investors. All the people making decisions are trying to save every bit of money possible.
Surely you realize heat transfer efficiency isn’t linked to the cost of water. Which doesn’t even show up on the balance sheet.
100 * 0 = 100000000 * 0
Do you genuinely think I didn't know businesses want to save money? Why are you telling me this?
You seem to have a hard time understanding that water is used because it is cheaper than the alternatives which already exist. This new development won't replace water while the water remains cheap.
Are you talking about evaporative cooling? Because this new system still very much uses water, in a closed loop.
And I'm aware water is cheap, it falls out of the sky.
After your previous comment, i thought that about you as well.
Why do people keep acting like a company wanting to save money is a revelation? It's so blindingly obvious, there's no need to tell everyone all the time?
You're the one who asked. Don't ask questions you don't want answers to, i guess?
Their argument was that companies don't care about efficiency, they just want to save money. Without realising they're the same thing. As far as I can tell, they were arguing with themselves.
Still gonna be using tons of energy, so hit me up when they claim 100% reduction in energy and I'm interested.
It sounds like genuinely cool technology in multiple ways. A water block on every single major component, and no cooling fans at all.
That would also be a very quiet room, rather than having thousands of tiny little fans screaming all the time.
The failure domain becomes everything below the box that leaks?
There’s nothing wrong with air cooling.
Did you miss the part about millions of dollars in energy savings per year?
