Abstract
The compact electrical generator sets have separate cooling airflows for the cylinder of the driving internal combustion engine, for the electrical generator, and for the components which generate most of the heat. Providing separate airflows allows to reduce the size of the generator set. Use of an alternator and an electronic controller for converting the electrical energy generated by the alternator to electrical energy of the type required by the user simplifies the design. The design of the cooling airflow with multiple combined and separated airflows reduces both size of the generator set and reduces losses due to generating the airflows.
Claims5
An internal combustion engine generator set comprising
- a frame structure having mounted therein
- an internal combustion engine having a cylinder, a crankshaft and a drive shaft,
- an electrical generator directly coupled to said drive shaft of said internal combustion engine,
- an electrical controller;
- said electrical generator having a rotor mounted on a driven shaft and having means for generating a magnetic field, a stator including windings for generating an electrical current,
- said rotor and said stator including openings for passing cooling air in axial direction
- means for generating an air flow,
- means for dividing said cooling air having past through said generator into a first and a second cooling air stream,
- first means for cooling said cylinder using said first cooling air stream,
- an airflow duct for cooling said electrical controller using said second cooling air stream.
