Coolant - Wikipedia

Gases. Air is a common form of a coolant. Air cooling uses either convective airflow (passive cooling), or a forced circulation using fans.. Hydrogen is used as a high-performance gaseous coolant. Its thermal conductivity is higher than all other gases, it has high specific heat capacity, low density and therefore low viscosity, which is an advantage for rotary machines susceptible to windage
