Heat Transfer Oil

Heat transfer oil is a type of oil used to transfer heat from a source to a destination. This oil serves as a heat transfer medium between different surfaces in thermal devices and systems. The features and applications of heat transfer oil include:

• High Operating Temperature:
  Heat transfer oil must be capable of functioning at high temperatures, so it is usually produced from base materials with a high working temperature.

• Thermal Stability:
  This oil should have good thermal stability to perform well under different temperature conditions and prevent changes in its properties due to heat exposure.

• Thermal Insulation Properties:
  Heat transfer oil must have good thermal insulation properties to prevent heat loss to the external environment and direct heat transfer to the required areas.

• Oxidation Resistance:
  Due to exposure to air and oxygen in thermal systems, heat transfer oil must have good resistance to oxidation (degradation due to oxygen exposure).

• Wear Resistance:
  Anti-wear properties and resistance to friction play an important role in heat transfer oil, as surface wear in thermal systems can reduce the oil’s useful life.

• Compatibility with Water and Water-Cooling Systems:
  In some thermal systems, heat transfer oil is used in direct heat exchange with water and cooling systems, so it must be compatible with these systems.

• Acid Neutralization:
  Acid-reducing properties in heat transfer oil help control acid formation and extend the oil’s service life.

• Compatibility with Sealing Materials:
  Heat transfer oil must be compatible with sealing materials used in thermal systems.

• Resistance to Chemicals:
  In some thermal systems, the oil must be compatible with the chemicals used in the system.

• Thermal Decomposition Resistance:
  Heat transfer oil must resist thermal decomposition and the formation of resins and deposits.

• Pressure Resistance:
  In some thermal systems, heat transfer oil operates under relatively high pressures, so it must have appropriate pressure resistance.

The working temperature range, type of thermal system, and specific requirements related to heat transfer significantly influence the choice of heat transfer oil.
