2. Oil cooling - Wikipedia

   en.wikipedia.org/wiki/Oil_cooling

   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. The cooled oil flows back into the hot object to cool it continuously.

3. Viscosity index - Wikipedia

   en.wikipedia.org/wiki/Viscosity_index

   Additionally, there are the issues of oil temperature maintenance, such as oil or engine heaters that enable easy starting and shorter warm-up period in very cold climates, and oil coolers to dump enough heat from the oil, and thus the engine, gearbox, or hydraulic oil circuit, so as to keep the oil's upper temperature to within a specified ...

   A simple open center hydraulic circuit. An excavator; main hydraulics: Boom cylinders, swing drive, cooler fan, and trackdrive Fundamental features of using hydraulics compared to mechanics for force and torque increase/decrease in a transmission. Hydraulic machines use liquid fluid power to perform work. Heavy construction vehicles are a ...

   A Honeywell refinery producing green diesel from natural oils in Pasadena, Texas.. The UOP Riverside research and development laboratory in McCook, Illinois was conceived in 1921 by Hiram J. Halle, the chief executive officer of Universal Oil Products (now simply UOP), as a focal point where the best and brightest scientists could create new products and provide scientific support for the oil ...

6. Coolant - Wikipedia

   en.wikipedia.org/wiki/Coolant

   Many oils have uses encompassing heat transfer, lubrication, pressure transfer (hydraulic fluids), sometimes even fuel, or several such functions at once. Mineral oils serve as both coolants and lubricants in many mechanical gears. Some vegetable oils, e.g. castor oil are also used. Due to their high boiling points, mineral oils are used in ...

7. Cryocooler - Wikipedia

   en.wikipedia.org/wiki/Cryocooler

   The Joule-Thomson (JT) cooler was invented by Carl von Linde and William Hampson so it is also called the Linde-Hampson cooler. It is a simple type of cooler which is widely applied as cryocooler or as the (final stage) of coolants. It can easily be miniaturized, but it is also used on a very large scale in the liquefaction of natural gas.
