Kylmäneneste

Kylmäneneste, often translated as coolant or antifreeze, is a fluid used in mechanical systems to regulate temperature. Its primary function is to absorb heat from a component and then dissipate that heat elsewhere, preventing overheating. This is particularly crucial in internal combustion engines where combustion generates significant thermal energy.

The composition of kylmäneneste typically involves a base fluid, often water or a mixture of water and glycols such as ethylene glycol or propylene glycol. These glycols serve to lower the freezing point and raise the boiling point of the mixture, expanding its operational temperature range. Additives are also incorporated to provide corrosion inhibition, lubrication for water pumps, and to prevent the formation of foam.

The effectiveness of kylmäneneste is measured by its specific heat capacity, thermal conductivity, and its ability to remain stable across a wide range of temperatures. A properly maintained cooling system, with the correct concentration of kylmäneneste, is essential for the longevity and efficient operation of many machines. If the concentration is too low, the fluid may freeze in cold conditions or boil in hot conditions. If the concentration is too high, it may reduce heat transfer efficiency. Regular testing and replacement of kylmäneneste are recommended maintenance practices.
