Where does the water go after being used for cooling?
- bunabhucan 4y agoIt evaporates, the heat is used to evaporate the water.
- betaby 4y agoDo they heat it that much to evaporate a lot of it? I've read about one water cooled DC, don't remember which one exactly. But I do remember they were drawing water at around 15C and returning back to the river at 20C.
- kevin_thibedeau 4y agoThey're using evaporative cooling. It isn't just a basic heat exchanger.
- alexvoda 4y agoDumb question, but can't they condense the water and collect it somewhere?
- ksec 4y agoSame question. Why cant it be a closed loop system?
- justsomehnguy 4y agoDC would cook itself in a couple of hours. Closed loop system for a system this big and hungry would demand many km^2 of radiators with a forced air-flow. Look at your A/C external unit - it's barely handles 10-15C degree difference for a small room and that is for a human with a measly 300-500 BTU/h. A typical server is 2000 to 6000 BTU/h, depending on the configuration and a typical 42U rack would have at least 10-15 servers, not counting TOR switches and other shenanigans.
- PM_me_your_math 4y agoThe hydrological cycle is already a closed loop system. The water you drink today watered a plant 10,000 years ago, passed through Abraham Lincoln's kidneys, or was drank by Genghis Khan.
- adgjlsfhk1 4y agohow does that work? the chips are only 95°C do you use a refrigerant cycle to gain heat from there? it's hard to see how you could make this work
- ikekkdcjkfke 4y agoMaybe they could borrow cooling technology from the mechanism used by humans on hot days
