ABSTRACT:
A cooling shell arrangement is assembled about an outer periphery of a housing of a dynamoelectric machine. The cooling shell arrangement comprises at least two extruded sections of arcuate shaped cooling members having cooling fins and at least two locking members fixedly holding the at least two sections in a predetermined position on the outer peripheral surface of the housing so that elongation of the at least two sections caused by thermal expansion is accommodated by the at least two locking members. Hoop tension is maintained in the at least two sections over a predetermined temperature range. The cooling shell arrangement improves the transfer of heat from the outer peripheral surface of the housing.
