24 Facts About Water cooling

Water cooling is a method of heat removal from components and industrial equipment.

Evaporative cooling using water is often more efficient than air cooling.

Water cooling is inexpensive and non-toxic; however, it can contain impurities and cause corrosion.

Water cooling is commonly used for cooling automobile internal combustion engines and power stations.

Water cooling coolers utilising convective heat transfer are used inside high-end personal computers to lower the temperature of CPUs.

Water cooling is inexpensive, non-toxic, and available over most of the earth's surface.

Water cooling has unusually high specific heat capacity among commonly available liquids at room temperature and atmospheric pressure allowing efficient heat transfer over distance with low rates of mass transfer.

Water cooling accelerates corrosion of metal parts and is a favorable medium for biological growth.

Water cooling contains varying amounts of impurities from contact with the atmosphere, soil, and containers.

Water cooling can accelerate corrosion of machinery being cooled as both an electrical conductor and solvent for metal ions and oxygen.

Water cooling returned to aquatic environments at temperatures higher than the ambient receiving water modify aquatic habitat by increasing biochemical reaction rates and decreasing oxygen saturation capacity of the habitat.

An open water cooling system makes use of evaporative cooling, lowering the temperature of the remaining water.

Water cooling has a boiling point temperature of around 100 degrees C at atmospheric pressure.

Automotive and many other engine cooling applications require the use of a water and antifreeze mixture to lower the freezing point to a temperature unlikely to be experienced.

Water cooling is however sometimes used for thyristors of HVDC valves, for which the use of deionized water is required.

Liquid Water cooling techniques are increasingly being used for the thermal management of electronic components.

Water cooling often adds complexity and cost in comparison to air cooling design by requiring a pump, tubing or piping to transport the water, and a radiator, often with fans, to reject the heat to the atmosphere.

Water cooling can be used to cool many computer components, but usually it is used for the CPU and GPUs.

Water cooling usually uses a water block, a water pump, and a water-to-air heat exchanger.

The downside of phase-change or thermoelectric Water cooling is that it uses much more electricity, and antifreeze must be added due to the low temperature.

Plant transpiration and animal perspiration use evaporative Water cooling to prevent high temperatures from causing unsustainable metabolic rates.

Machine guns used in fixed defensive positions sometimes use water cooling to extend barrel life through periods of rapid fire, but the weight of the water and pumping system significantly reduces the portability of water-cooled firearms.

Water cooling-cooled machine guns were extensively used by both sides during World War I, however by the end of the war lighter weapons which rivalled the firepower, effectiveness and reliability of water-cooled models began to appear on the battlefield, thus water-cooled weapons have played a far lesser role in subsequent conflicts.

In 2018, researchers from the University of Colorado Boulder and University of Wyoming invented a radiative Water cooling metamaterial known as "RadiCold", being developed since 2017.
