  • Modular radiator for an engine-generator set
    Patent number: 5778832
    Abstract: An apparatus for generating electricity includes an internal combustion engine having a drive shaft connected to an electrical generator. A radiator, through which coolant from the engine circulates, is formed by a six sided enclosure with radiator cores forming three, four or five of the six sides. The radiator has a tank mounted above and connected to the three radiator cores to serve as a coolant plenum and as a collector for air entrapped in the coolant. A fan is mounted either inside or outside the radiator enclosure, adjacent to one of the six sides, and is driven by the engine drive shaft or an electric motor. A muffler for the engine may be located within radiator enclosure and cooled by air flowing therethrough.
