CPC Definition - Subclass F01P
This place covers:
Cooling of machines, where "machine" means a device which could equally be an engine and a pump, and not a device which is restricted to an engine or one which is restricted to a pump.
Cooling of engines, where "engine" means a device for continuously converting fluid energy into mechanical power, e.g. steam piston engines or steam turbines.
Cooling of internal combustion engines.
This place does not cover:
Cooling of machine tools | |
Arrangements in connection with cooling of propulsion units in vehicles | |
Heat-exchange or heat-storage materials | |
Cooling of gas-turbine engines | |
Profiting from the waste heat of the exhaust gases | |

Attention is drawn to the following places, which may be of interest for search:
Cooling by lubricant when the lubrication aspect predominates |
In this place, the following terms or expressions are used with the meaning indicated:
Air | gaseous cooling fluids |
Liquid cooling | includes also cooling where liquid is used as the heat transferring fluid between parts to be cooled and the air, e.g. using radiators |
Air cooling | direct air cooling and thus excludes indirect air cooling occurring in liquid cooling systems as explained herefore |
Cooling air | directly or indirectly acting air for cooling |
Engine | device for continuously converting fluid energy into mechanical power. Thus, this term includes, for example, steam piston engines or steam turbines, per se, or internal-combustion piston engines, but it excludes single-stroke devices. "Engine" also includes the fluid-motive portion of a meter unless such portion is particularly adapted for use in a meter |
Machine | device which could equally be an engine and a pump, and not a device which is restricted to an engine or one which is restricted to a pump |
This place covers:
Air cooling of the engine parts as cylinders or cylinder heads, but also cooling of the engine room, when related to the engine cooling circuit.
