Patent number: 9543809Abstract: A radial vent composite heat pipe system for cooling and increasing the power density of an electrical machine is provided. The system comprises a plurality of radial vent composite heat pipe assemblies each comprising a slot portion thermally connected to a vent portion. The slot portions are disposable within respective stator slots of a stator core pack of a stator assembly of the electrical machine. The vent portions are disposable within stator vents of the stator assembly. The slot portions absorb heat from the stator coils of the stator assembly and transfer the absorbed heat to the vent portions. The vent portions reject the transferred heat into a cooling air flowing through the respective stator vent, thereby rapidly transferring heat from the respective stator coil to the cooling air flowing through stator vent, and thereby greatly increasing the power density of the electrical machine.Type: GrantFiled: February 25, 2014Date of Patent: January 10, 2017Assignee: HPEV, Inc.Inventors: Mark Hodowanec, Timothy J.

Patent number: 8283818Abstract: A motor that includes a motor portion structured to house a stator and a rotor mounted to a shaft of the motor. The motor additionally includes a cooling portion disposed adjacent to the motor portion and separated from the motor portion by a structural interface. The cooling portion provides a cooling chamber structured to have a cooling fluid passed therethrough via a cooling fluid moving device that is structured to be coupled to and driven by the motor shaft. Furthermore, the motor includes a plurality of heat pipes having evaporator ends disposed within the motor portion and condenser ends disposed within the cooling chamber. During operation of the motor and cooling fluid moving device, the cooling fluid contacts the heat pipe condenser ends to extract heat from the condenser ends, hence cooling the evaporator ends of the heat pipes, thereby cooling the motor portion of the motor and the stator and rotor housed therein.Type: GrantFiled: July 31, 2009Date of Patent: October 9, 2012Assignee: HPEV, Inc.Inventors: Timothy Hassett, Mark Hodowanec

Patent number: 8148858Abstract: A totally enclosed motor comprising a housing totally encloses an electrical package that includes plurality of slot vents extending radially outward from a shaft on which the electrical package is mounted. The electrical package being operable to generate a closed circuit electrical package cooling air flow that circulates through the slot vents and is confined within the housing. The motor additionally including an exterior cooling assembly that is operable to generate a directed exterior air flow along an exterior portion of the housing. The motor further including a plurality of heat pipes having evaporator ends disposed within the closed circuit electrical package cooling air flow and condenser ends disposed within the exterior air flow, whereby heat is removed from the electrical package chamber such that the ‘Totally Enclosed’ more provides a power output substantially equivalent to that of an ‘Open’ motor of approximately the same size.Type: GrantFiled: August 6, 2009Date of Patent: April 3, 2012Assignee: HPEV, Inc.Inventors: Timothy Hassett, Mark Hodowanec

Patent number: 8134260Abstract: A motor including a frame that defines a motor portion and an adjacent cooling portion, and a plurality of heat pipes disposed within and fully enclosed by the motor frame. Each heat pipe has an evaporator end disposed within the portion of the frame that defines the motor portion and a condenser end disposed within the portion of the frame that defines the cooling portion. A cooling chamber within the motor cooling portion is structured to have a fluid introduced therein by a working device such that at least a portion of the frame defining the cooling portion is cooled via the working fluid, thereby extracting heat from the heat pipe condenser ends and cooling the motor portion of the motor.Type: GrantFiled: July 31, 2009Date of Patent: March 13, 2012Assignee: HPEV, Inc.Inventors: Timothy Hassett, Mark Hodowanec
