And looks badass!!

> The cooler's dissipation ability is impressive enough, but the liquid that goes out of it is claimed to be at 60 to 80°C, making it easy to recover and use in other heating networks for a double-whammy. The report claims these figures are superior to standard datacenter cooling that whisks away heat at lower temperatures, making it harder to reuse.

Two immediate thoughts, first, how much hotter are the chips then? But second, how do we rate it consider this, what is the figure of metric or unit of measure that represents outlet temperature?

My gut says that yeah, we want to use as much of the thermal potential as we can, dissipate as much heat into the water as possible. And the idea of maybe possibly recuperating some of this energy also feels like it would go up.

Nice. Data centers could double as hot springs.

Since when does cooling get measured in watts?

But/hr is convertible to watts. It's how much energy per hour gets removed from the space.

It's the SI unit, what else do you want to use lol?

Americans measure it in bald eagle wing flaps per football fields but that's just an American thing

HVAC companies in the US exclusively use ‘tons’ to describe the amount of heat a chiller or heat pump can move. Trane, Daikin, and more all use ‘tons’ on both their marketing and engineering material.

1 ton ~= 3.56kW, but a 1-ton chiller will use ~= 1kW of electricity to remove 3.56kW of heat due to the COP of 3-4 for an air cooled chiller.

That's really not appropriate for the topic at hand. And what happens when the technology improves and the 1 kW ~= 3.65 kW relation changes?

The COP isn't constant either. I can drop to 1:1 or even lower if you need to run the anti frost resistance

Good marketing gimmick though

Since every cooler review took payola to pump bogus performance charts so they never settled on scientific measurements.

For those wondering, the standard measure is thermal resistance in degrees per watt, for linear systems - doubling the heat that needs to be transferred doubles the temperature difference between the sides. Adding in heat pipes, liquid convection, etc is going to make the system non-linear, so then it makes sense to talk in terms of the delta-T at given wattages. And then since there are phase-change materials, the working temperature should be specified as well. Yes, there are three scalars before you even get to things like scaling fan speed.

(I'm not a mechE so I'm sure there's something I'm missing still)
