jäähdytysnestelämpötilaa

Jäähdytysneste, commonly known as antifreeze in English, is a liquid used in closed-loop cooling systems, most notably in internal combustion engines. Its primary function is to prevent the coolant from freezing in cold temperatures and boiling in hot temperatures, thereby maintaining optimal operating temperatures for the engine. A typical jäähdytysneste is a mixture of water and a base chemical, usually ethylene glycol or propylene glycol.

The glycol component lowers the freezing point of the mixture significantly below that of pure water, preventing the formation of ice crystals that could damage engine components. Simultaneously, it raises the boiling point of the coolant, allowing the engine to operate at higher temperatures without the coolant boiling over. This wider operating temperature range is crucial for efficient engine performance and longevity.

In addition to its freezing and boiling point modification properties, jäähdytysneste contains additives that protect the cooling system from corrosion and scale formation. These inhibitors form a protective layer on metal surfaces within the engine, preventing rust and other forms of chemical degradation. The color of jäähdytysneste varies depending on the manufacturer and the type of inhibitors used, but common colors include green, red, blue, and yellow. Regular checks and maintenance of the jäähdytysneste level and condition are essential for ensuring the proper functioning and protection of the cooling system.
