Abstract
An oil cooled generator may have stator windings with first portions in contact with a stator core and second non-contact portions. One or more nozzles may be configured to provide a spray pattern of oil which impinges on the non-contact portions even though the nozzles may have orifices oriented so that the lines projected in alignment with longitudinal axes of the orifices do not intersect the non-contact portions of the stator windings.
Claims20
An oil cooled generator comprising:
- stator windings with first portions in thermally-conductive contact with a stator core and second non-contact portions not in such contact;
- and
- one or more nozzles having a cylindrical orifice with a longitudinal axis oriented so that a line projected in alignment with the axis does not intersect the non-contact portions of the stator windings,
- the one or more nozzles configured to provide a spray pattern of oil which impinges on the non-contact portions.
An oil spray system for cooling selected portions of a generator, comprising:
- one or more nozzles with an orifice interconnected with a passageway for oil;
- the orifice having a diameter large enough to pass an integral stream of oil;
- the orifice having a longitudinal axis oriented so that a line projected in alignment with the axis does not intersect the non-contact portions of the stator windings that does not intersect the selected portions of the generator;
- the one or more of the nozzles having a deflection surface configured to produce a spray pattern of the oil which spray pattern impinges on the selected portions of the generator.
A method for cooling selected portions of a generator with an oil spray comprising the steps of:
- supplying pressurized oil to a passageway in the generator;
- passing at least a portion of the pressurized oil through at least one nozzle orifice interconnected with the passageway to form an integral stream of oil;
- projecting the integral stream of oil along a path that does not intersect the selected location;
- deflecting the integral steam and producing a spray pattern of the oil from the integral stream;
- and
- directing the spray pattern of the oil to impinge on the selected portions of the generator.
