the art of moving heat somewhere it can be someone else's problem.
means any mechanism that removes unwanted heat from a system faster than the system generates it.
from the principle predates the machines: ancient persians built windcatchers and ice pits by 400 bce, but the modern engineered version emerged with willis carrier's 1902 humidity-control unit for a brooklyn printing plant, which accidentally invented air conditioning.
data centersoften spend more on cooling than on computing itself
human bodysweats roughly one liter per hour of hard cooling
nuclear plantslose power output if river water gets too warm
phase changeevaporating liquid absorbs far more heat than just warming it
for instance
chernobyl reactor 4 — cooling failure triggered the 1986 meltdown
google's dalles datacenter — uses river water evaporation instead of chillers
car radiator — circulates coolant through fins since karl benz's 1885 design
cern's helium loop — chills magnets to 1.9 kelvin, colder than deep space
