F01P COOLING OF MACHINES OR ENGINES IN GENERAL; COOLING OF INTERNAL-COMBUSTION ENGINES (arrangements in connection with cooling of propulsion units in vehicles B60K11/00; heat-transfer, heat-exchange or heat-storage materials C09K5/00; ; heat exchange in general, radiators F28)
Description
F01P covers cooling systems and methods for heat dissipation in machines and engines, with particular emphasis on internal-combustion engines. This includes cooling apparatus such as radiators, heat exchangers, cooling fans, thermostatic controls, and liquid or air cooling circuits designed to maintain optimal operating temperatures. The classification encompasses both the mechanical components and functional designs of cooling systems across various engine types and industrial applications. Related cooling systems for specific engine categories (e.g., steam engines, turbines) may fall under their respective engine-specific classifications.
