In this sub-class, the following terms are used with the meanings indicated:
"Air" includes other gaseous cooling fluids.
"Liquid cooling" also embraces cooling where liquid is used as the heat-transferring fluid between parts to be cooled and the air, e.g. using radiators.
"Air cooling" means direct air cooling and thus excludes indirect air cooling occurring in liquid cooling systems as explained under (b).
"Cooling-air" embraces directly- or indirectly-acting cooling-air.
