Abstract

Some embodiments relate to an engine driven generator that includes a first electrical fan and a second electrical fan. The engine driven generator further includes a power source and a circuit connecting the power source to the first electrical fan and the second electrical fan. The circuit is configured to selectively connect the first electrical fan and the second electrical fan in series or in parallel. The circuit may operate the first electrical fan and the second electrical fan at full speed when the first electrical fan and the second electrical fan are electrically connected in parallel. The circuit may operate the first electrical fan and the second electrical fan at less than full speed when the first electrical fan and the second electrical fan are electrically connected in series.

Description

[0001] priority claim [0002] This application claims priority to U.S. Patent Application Serial No. 13 / 288,997, entitled "Engine Driven Generator Cooled by First and Second Electric Fans," filed November 4, 2011, The entire content of this application is hereby incorporated by reference. technical field [0003] Embodiments relate to a cooling system for an engine driven generator, the cooling system comprising a first electric fan and a second electric fan. Background technique [0004] Existing cooling systems for engine driven generators typically include a belt-driven fan used to remove heat from a radiator used to cool the engine. These belt-driven fans are usually driven by the engine itself. [0005] One of the disadvantages of having a belt-driven fan is that the fan requires the engine to be running in order to perform the cooling function. Furthermore, the belt-driven fan typically takes up valuable space within the housing that contains the engine-driven gen...
