Methods and apparatus are provided for an axial electric motor. The apparatus comprises, a stator having coils thereon for producing a magnetic field, a rotor rotated by the magnetic field, an output shaft coupled to the rotor, and a ring incorporating a coolant channel circumferentially engaging the stator for absorbing heat and reaction torque from the stator. It is preferable that that the ring have inwardly extending teeth that mesh with the coils on the stator. The space between the teeth and the coils is preferably filled with a substantially solid thermally conductive material to transmit stator reaction torque to the teeth and cool the stator. The coils are preferably formed from a flat ribbon a portion of whose principal surface is perpendicular to the teeth. A supporting frame is desirably fixedly coupled to the ring and rotatably coupled to the output shaft.

A gasifier system is provided that includes a gasification chamber spool that has a ceramic matrix composite (CMC) liner adapted to form a solidified slag protective layer on an interior surface of the liner from molten slag flowing through the gasification chamber spool. The gasification system additionally includes a heat exchanger (HEX) quench spool that also includes a CMC liner adapted to form a solidified slag protective layer on an interior surface of the liner from molten slag flowing through the HEX quench spool. Additionally, the HEX quench spool includes a parallel plate HEX core having a plurality of CMC panels. The CMC panels are adapted to form a solidified slag protective layer on exterior surfaces of each respective CMC panel from molten slag flowing through the HEX quench spool. Furthermore, each CMC panel includes a plurality of internal coolant channels adapted to exchange sensible waste heat from the hot product flowing through the HEX quench spool with a coolant flowing through the internal coolant channels. The sensible waste heat absorbed by the coolant is recovered by the gasification system by utilizing the heated coolant in various operational phases of the gasification system.

The present application provides a gas showerhead including a gas distribution and diffusion plate and a water cooling plate, the gas distribution and diffusion plate includes several columns of first gas diffusion passages connecting to a first reactant gas source and several columns of second gas diffusion passages connecting to a second reactant gas source; the water cooling plate having cooling liquid passages is arranged below the gas distribution and diffusion plate, and the water cooling plate is provided with first gas outlet passages provided for the reactant gas in the first gas diffusion passages to flow out and second gas outlet passages provided for the reactant gas in the second gas diffusion passages to flow out, so as to isolatedly feed at least two reactant gases into a reaction chamber.

An outer rotor motor comprises a tubular shaft for maximum motor cooling effect. Coolant may flow through coolant channels of the shaft and the motor in various configurations to carry away the heat. A thermally conductive component may be inserted into the hollow shaft under the stator section to optimize the airflow and cooling. Physical construction of the motor and control algorithms may further enhance motor performance with appropriate sensors. A compact, smooth, and cool operating motor may thus be achieved for applications such as treadmills or other belt drive systems.

A microwave surgical ablation probe having an arrangement of coolant channels in fluid communication with a cooling chamber disposed within the distal end of the probe is disclosed. A hypotube having one or more longitudinal ribs extending radially inward from an inner surface thereof is coaxially disposed around a coaxial feedline. The longitudinal ribs of the hypotube engage an outer sheath of the feedline to define a fluid inflow channel to deliver coolant to the cooling chamber, and a fluid outflow channel to receive fluid from the cooling chamber. The cooling chamber may be formed from porous ceramic or porous metallic material that provides structural support to the probe while permitting coolant to circulate therethrough. The probe includes dielectric and choke members that are adapted to control the microwave radiation pattern (e.g., ablation shape), and which may provide improved coupling of the probe to tissue.
