Abstract
An assembly including a winding and a cooler in contact with conductors of the winding, the cooler including a container forming a heat dissipator and including a phase change material having the ability to absorb a surplus quantity of heat when the conductors of the winding are subject to an increase in their current density and the heat dissipator is composed of at least two hollow parts separate and nestable with one another and intended to house the phase change material.
Claims12
An assembly comprising a stator, wherein the stator includes a plurality of teeth protruding from the stator such that each of the plurality of teeth forms a cooler in contact with conductors of a winding, the winding being formed from a plurality of conductors having a coil body and coil heads, the cooler comprising a container forming a heat dissipator and comprising a phase change material having the ability to absorb a surplus quantity of heat when the conductors of the winding are subject to an increase in their current density, wherein the heat dissipator is composed of at least two hollow parts separate and nestable with one another and intended to house the phase change material and wherein the heat dissipator is interposed between the coil body and the coil heads.
