Note(s)
In this subclass, the following terms or expresions are used with the meanings indicated:
"air" includes also other gaseous cooling fluids;
"liquid cooling" also includes 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 liquid cooling above;
"cooling-air" includes directly- or indirectly-acting cooling-air.
