Common Coolant Types and Their Uses in Liquid Cooling Systems

摘要

Using liquids for heat transfer is an important cooling method in many industries. Selection of the best heat transfer fluid for a cooling system involves consideration of performance, compatibility and maintenance factors. Water has excellent heat transfer properties, making it somewhat of a standard for comparison to other coolant fluids. Among heat transfer fluids, water has superior properties in many regards, with a high specific heat of around 4,200 J/kgK, low viscosity, and no flash point. On the other hand, it has a relatively narrow range of operation, as liquid temperatures leave plain water susceptible to freezing or boiling.
