Cooling and rejection of the heat in generators are usually realized by air, which is circulating in a closed cycle in the generator set. As shown in Fig. 1, the air produced by the rotor fan exits radially from the ducts provided between the stator plates after passing the rotor parts (i.e. poles, etc.) and is sucked again into the generator by the rotor fan after being cooled

air cooled vs liquid cooled generator: which one should you choose?

Air-cooled generator is a type of generator that uses air as a cooling medium to dissipate the heat generated during operation. This type of design is prevalent in portable and standby generators. It usually consists of fans, fins, and other components that help dissipate the heat generated by the engine and generator components.
