What is oil cooling?

oil cooling is the heat removal process from machines and electrical components with oil as a transmission medium. The process usually involves circulating cool oil around the heat source, allowing it to absorb thermal energy and then circulate hot oil on the cooling mechanism where it sheds heat. The oil is the ideal liquid of the coolant because it has a higher boiling point than water. Oils in cooling applications are usually mineral varieties produced as by -products in the oil refine process.

However, although oil is often not like a "cold" liquid, but still makes a suitable coolant medium. It easily absorbs thermal energy and has a boiling point higher than water, allowing it to be used to cool components with temperatures higher than 212 ° F (100 ° C). It is also an electrical insulator when without moisture and dirt.

This form of cooling is usually a process of immersion where heat sources work in an oil bath. The process relies on the thermal energy absorbing oil from direct koNtact with hot device. After heating, the oil is then circulated by a convection or pumped from contact with the heat source into the cooler, where it throws heat into water or air. It then moves back to the heat source to repeat the cycle. This process is a good example of cooling heat transfer, where the thermal energy moves or transmits from a source of high temperature to a washbasin or low temperature absorber.

oils used in oil cooling applications are usually mineral varieties, although plant varieties are sometimes used. These oils are by -improvement of oil and are usually low to medium viscosity, colorless combinations of alkans and cyclic paraffins. Several ingredients are included in cooling oils to increase their performance, including Corona and Arc suppression, fire retarders and corrosion inhibitors.

electric oil cooling applications include transformers, Swindgear and Oil Bath Welding machines. The oil is also used to cool high -performance electronic parts; SeveralExperimental computers contain main boards and processors completely immersed in mineral oil. The application of mechanical cooling of the oil includes turning operations such as cutting, milling and rotation, where the oil is used to lubricate and cool the tip of the tool. Lubricating oil in automotive engines also serves as a coolant, thereby absorbing heat from the combustion area and releases it with a separate oil cooler or spare oil in the engine. Large industrial gearboxes and power trains also use combined oil lubrication and cooling.
