Methods for cooling process chamber components are provided herein. In some embodiments, a method of cooling a process chamber component may include reducing a power provided to a heater disposed proximate a surface of the process chamber component to reduce an amount of heat provided to the component by the heater; providing a coolant to coolant channels disposed within the process chamber component using a pulsed flow having a duty cycle until the process chamber component reaches a temperature that is less than or equal to a predetermined magnitude above a temperature of the coolant; and after the process chamber component reaches the temperature less than or equal to the predetermined magnitude above a temperature of the coolant, reducing the duty cycle of the pulsed flow of the coolant to zero.

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.

Apparatus and method are provided for facilitating cooling of air passing through an electronics rack. The apparatus includes a heat exchange assembly hingedly mounted above and external to the rack, such that air passing above the rack from an air outlet side to an air inlet side thereof passes through the heat exchange assembly, and is cooled. The heat exchange assembly includes a support structure to support hinged mounting of the assembly above the rack, and an air-to-liquid heat exchanger coupled to the support structure. The heat exchanger has an inlet plenum and an outlet plenum in fluid communication with respective connect couplings which facilitate connection of the plenums to coolant supply and return lines, respectively. The heat exchanger also includes heat exchange tube sections, each of which has a coolant channel with an inlet and an outlet coupled to the inlet and outlet plenums, respectively.

A turbine airfoil (22E-H) extends from a shank (23E-H). A platform (30E-H) brackets or surrounds a first portion of the shank (23E-H). Opposed teeth (33, 35) extend laterally from the platform (30E-H) to engage respective slots (50) in a disk. Opposed teeth (25, 27) extend laterally from a second portion of the shank (29) that extends below the platform (30E-H) to engage other slots (52) in the disk. Thus the platform (30E-H) and the shank (23E-H) independently support their own centrifugal loads via their respective teeth. The platform may be formed in two portions (32E-H, 34E-H), that are bonded to each other at matching end-walls (37) and / or via pins (36G) passing through the shank (23E-H). Coolant channels (41, 43) may pass through the shank beside the pins (36G).

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.

A prismatic-cell battery pack is provided with integral coolant passages including an intake plenum, an exhaust plenum, and a distributed array of coolant channels coupled between the intake plenum and the exhaust plenum. Coolant medium forced into the intake plenum enters the coolant channels in parallel, draws heat away from the battery cells, and then enters the exhaust plenum for expulsion into the atmosphere. The battery pack is configured as a set of stackable interlocking battery cell modules including at least one battery cell in thermal proximity to an array of coolant channels distributed over the profile of the battery cell, and a pair of peripheral chambers joined to opposite ends of the coolant channels to form the intake and exhaust plenums when the modules are arranged and interlocked in a lineal stack.
