ELECTRIC MACHINE MODULE COOLING SYSTEM AND METHOD

摘要

Some embodiments of the invention provide an electric machine module including a housing that defines a machine cavity. A coolant jacket can be at least partially defined by the housing. In some embodiments, a plurality of coolant apertures can be disposed through portions of the housing to fluidly connect the coolant jacket and the machine cavity. One or more solenoid assemblies can be at least partially supported by the housing and positioned substantially adjacent to at least some of the coolant apertures. The solenoid assemblies can be configured to regulate passage of a coolant into the machine cavity from the coolant jacket.
