Abstract: A heat pipe assembly includes walls having porous wick linings, an insulating layer coupled with at least one of the walls, and an interior chamber sealed by the walls. The linings hold a liquid phase of a working fluid in the interior chamber. The insulating layer is directly against a conductive component of an electromagnetic power conversion device such that heat from the conductive component vaporizes the working fluid in the porous wick lining of the at least one wall and the working fluid condenses at or within the porous wick lining of at least one other wall to cool the conductive component of the electromagnetic power conversion device. The assembly can be placed in direct contact with the device while the device is operating and/or experiencing time-varying magnetic fields that cause the device to operate.

Abstract: An electric motor may include a stator assembly comprising a stator housing, and one or more rotors coupled to the stator by a rotor shaft assembly. The stator housing may include a cooling structure that has a plurality of cooling body portions and a plurality of cooling conduits defined by the plurality of cooling body portions. A method of forming a stator housing for an electric machine may include additively manufacturing a stator housing that includes a cooling structure defining a fluid domain, coupling a working fluid source to the stator housing and introducing a working fluid into the fluid domain defined by the cooling structure, and sealing the cooling structure with the working fluid contained within the fluid domain of the cooling structure. A method of cooling an electric machine may include heating the working fluid in the fluid domain and flowing the working fluid through the fluid domain, and transferring heat from the cooling structure to a cooling fluid flowing along one or more cooling surfaces contacting a surface of the electric machine.

Abstract: A hydraulic actuator for a downhole pump system includes a piston housing having a head end and a base end. A drive piston is movable within the piston housing between a first piston position proximate to the head end and a second piston position proximate to the base end. The hydraulic actuator includes a control valve that translates between a first control valve position in which fluid is directed into the base end and a second control valve position in which fluid is directed into the head. When the piston moves to the first piston position, a mechanical positon feedback system translates the control valve from the first control valve position to the second control valve position. When the piston moves to the second piston position, the mechanical positon feedback system translates the control valve from the second control valve position to the first control valve position.
