ABSTRACT:
A motor-containing device, particularly a submersible pump of the type including a sealed housing and motor mounted within the housing, includes a heat conducting filler material disposed in the gap between the motor and internal surface of the housing walls to improve the transfer of motor-generated heat from the motor to the housing walls. The filler material is such that it can be disposed in the gap in an initial form or state without concern for matching the exact dimensions of the gap and subsequently transformed while in the gap to provide a layer that fills the gap and provides a path for heat conduction to the housing walls. In one form, the filler material comprises a high memory thermoplastic that is mechanically prestretched into relatively thin sheet form, added to the gap during assembly of the pump, and then expanded in the gap by the application of heat thereto. In another form, the filler material comprises a thermoplastic material exhibiting high thermal expansion. This material is initially cooled to a contracted thickness and then inserted in the gap where it expands naturally to its original or greater thickness in response to increases in the temperature within the housing. In still another form, the filler material comprises a settable liquid such as an epoxy that is injected into the gap in a liquid state and then allowed to set or harden in the gap to provide the heat conducting layer.
