Water cooling

Water-cooling is a method of heat removal from components. Contrary to air cooling, Water-cooling uses water as the heat transmitter and is commonly used for cooling internal combustion engines in automobiles and electrical generators. Other uses of Water-cooling include cooling the lubricant oil of pumps; for cooling purposes in heat exchangers; and cooling products from tanks or columns.

The a Water-cooling dvantages of using water cooling over air cooling include water's higher specific heat capacity, density and thermal conductivity, meaning water in Water-cooling can transmit heat over greater distances with much less volumetric flow and reduced temperature difference. This leads to the primary advantage water-cooling enjoys over conventional heat sinks: the tremendously increased ability to transport heat away from source to a secondary cooling surface allows for large, more optimally designed radiators rather than small, inefficient fins mounted on or near a heat source such as a CPU core.

A disadvantage of water cooling is the risk of damage from freezing. Automotive and many other engine cooling applications require the use of a water (Water-cooling )and Antifreeze mixture to lower the freezing point to a temperature unlikely to be experienced. Anti-freeze also inhibits corrosion from dissimilar metals and can increase the boiling point, allowing a wider range of water cooling temperatures. It's distinctive odor also alerts operators to cooling system leaks and problems that would go unnoticed in a water-only cooling system in Water-cooling.

Another less common chemical additive is a product to reduce surface tension. These additives are meant to increase the efficiency of automotive cooling systems. Such products are used to enhance the cooling of underperforming or undersized cooling systems or in racing where the weight of a larger cooling system could be a disadvantage.

A typical watercooling setup consists of an object to be cooled, a pump which circulates the water and a radiator such as a large heatsink (possibly with a fan). These components are linked by tubes.

An optional watercooling component is a reservoir, which helps to prevent the formation of air bubbles in the system. However, if the watercooling system is properly configured and sealed, there is no need for a reservoir, though it does make the system much easier and less time-consuming to fill. Another option is simply using an inexpensive T-Line. There is no need for either of these components, though one is recommended to make the operation quicker to fill and bleed.
