Abstract
The cooling system of the present disclosure is configured to promote heat transfer in a gearbox. The system can include a container for housing a gas, the gas having a sufficient percentage of helium so that once the gas is introduced into the gearbox, the helium increases heat transfer from the heat generating components of the gearbox. The method of the present disclosure can include selectively introducing the helium gas into the gearbox.
