The coolant diverter has a first plate for dividing the coolant diverter into a first cavity and a second cavity. The second cavity positioned adjacent the power semiconductor device. The first plate further includes an opening to fluidly couple the first cavity with the second cavity such that the liquid coolant flows into the first cavity, through the opening in the first plate, and into the second cavity to cool the power semiconductor device. The first cavity has a cross-sectional area that generally decreases in a downstream direction, and the second cavity has a cross-sectional area that generally increases in the downstream direction.

摘要： A fuel cell system and process using an organic Rankine cycle to produce shaft work to operate a fuel cell system component such as an air compressor. The air compressor delivers compressed air to a fuel cell stack. The steps of the Rankine cycle include pumping a liquid working fluid to an elevated pressure, heating the fluid to a gas, expanding the high temperature and high-pressure gas through an expander to produce shaft work used to drive a fuel cell system component such as an air compressor, and then removing energy from the cooling fluid to change the gas back to a liquid, and repeating the cycle. The liquid fluid can be heated by an external boiler, or one of the components of the fuel cell system such as the combustor and/or the fuel cell stack.

摘要： An oil cooled inductive coupler for use with an inductive charging system that charges propulsion batteries of an electric vehicle. The coupler is connected to a power source by way of a coaxial cable that has power conductors for coupling power to the coupler, and cooling channels for coupling high dielectric strength cooling fluid to and from the coupler. The coupler has a housing with a flood box formed therein having an open interior that forms a conductor termination area. The cooling channels are coupled to the flood box, and the power conductors are terminated in the termination area and are exposed to the cooling fluid that is pumped therethrough to cool them. A heat exchanger having a fluid flow path therethrough is coupled to the flood box and permits the cooling fluid to circulate therethrough. A primary winding is secured or bonded to the heat exchanger, a magnetic puck is disposed in an opening in the heat exchanger, and upper and lower primary winding covers enclose the heat exchanger. The cooling fluid is pumped through the coaxial cable, the flood box and the heat exchanger to cool the primary winding, the magnetic puck, and the power conductors, to permit high power levels to be transferred between the power source and the propulsion batteries of the electric vehicle.
