Oil cooling is the use of engine oil as a coolant, typically to remove surplus heat from an internal combustion engine. The hot engine transfers heat to the oil which then usually passes through a heat-exchanger , typically a type of radiator known as an oil cooler .
However, properties of the coolant (water, oil, or air) also affect cooling. As example which compares water and oil as coolants, one gram of oil can absorb about 55% of the heat for the same rise in temperature (called the specific heat capacity). Oil has about 90% the density of water, so a given volume of oil can absorb only about 50% of the ...
More simply they may be oil-water coolers, where an oil pipe is inserted inside the water radiator. Though the water is hotter than the ambient air, its higher thermal conductivity offers comparable cooling (within limits) from a less complex and thus cheaper and more reliable [citation needed] oil cooler. Less commonly, power steering fluid ...
The tramp oil accumulation separates from the aqueous or oil based coolant and can be easily removed with an absorbent. Old, used cutting fluid must be disposed of when it is fetid or chemically degraded and has lost its usefulness. As with used motor oil or other wastes, its impact on the environment should be mitigated.
Motor oil is used for the lubrication, cooling, and cleaning of internal combustion engines. Motor oil may be composed of only a lubricant base stock in the case of mostly obsolete non-detergent oil, or a lubricant base stock plus additives to improve the oil's detergency, extreme pressure performance, and ability to inhibit corrosion of engine ...
After a year of testing with Green Revolution Cooling, the chip giant saw some of the best power usage efficiency ratings it's seen, with the oil-cooled PCs easily besting identical, air-cooled units.
