Oil cooling

From Wikipedia, the free encyclopedia

Oil cooling is the principle behind the device oil cooler. It refers to a process whereby heat is displaced from a 'hotter' object, into a cooler oil. The oil carrying the displaced heat usually passes through a cooling unit such as a radiator or less commonly a gas decompresser. The cooled oil repeats this cycle, to continuously remove heat from the object.

[edit] For and against

[edit] Advantages

  • Oil has a higher boiling point than water, so it can be used to cool items 100°C or higher
  • Oil is an electrical insulator, thus can be used inside of or in direct contact with electrical components.

[edit] Disadvantages

  • Coolant oil may be limited to cooling objects under temperatures greater than approximately 200°C - 300°C
  • Parts are hard to take out and put in after the oil is put in.

[edit] Gas cooling

For the instance where an object to be cooled is greater in temperature than the range a cooling oil can remain stable, a compressed cooled gas would be used. As compressed gas is decompressed, heat is absorbed from surroundings of the gas, in particular, the hot object.
