摘要： A radiative heatsink includes a cold plate, a radiator mounted to the cold plate and a thermal compound located between and coupling the heat source to the cold plate. The thermal compound converts a portion of a first phononic thermal energy from the heat source into a first photonic near-field and a first photonic far-field thermal radiation and transfers the first photonic near-field, the first photonic far-field and the remaining of the first phononic thermal energy to the cold plate. The cold plate combines the first photonic near-field, the first photonic far-field and the remaining first phononic thermal energy into a second phononic thermal energy and provides the second phononic thermal energy to the radiator. The radiator converts the second phononic thermal energy into a second photonic near-field and a second photonic far-field and emits the second photonic near-field or the second photonic far-field such that cold plate is regenerated.

摘要： A pumped fluorescent light source includes a parabolic mirror that is positioned to focus pumping light from one or more pump sources on a fluorescent body. The resulting assembly provides for heat collection from a back surface of the light source for both the fluorescent body and the pumping sources in a compact package that may be hermetically sealed. The parabolic mirror has reflective surfaces disposed outside of a collection area of an output beam of the light sources, so that the collection area is not obstructed by the parabolic mirror. The light source also includes a collecting lens for collecting the light emitted by the body. The parabolic mirror focuses the stimulus light on the fluorescent body to stimulate emission. An additional parabolic mirror may be included behind the fluorescent body to focus the fluorescent emissions that do not directly enter the collection area at a point of collection.

摘要： A semiconductor module is disclosed. The semiconductor module includes a housing that encloses on a bottom thereof a spacer and a wiring substrate that mounts a semiconductor element thereon. The housing includes a feedthrough that secures one end of a transmission substrate. The other end of the transmission substrate faces the wiring substrate and the spacer. The other end of the transmission substrate provides a lower end and an upper end that form an extension protruding toward the wiring substrate. The upper end is set so close to the wiring substrate but the lower end forms a space for receiving a surplus adhesive oozing between the spacer and the wiring substrate.

摘要： A laser cooling system includes a first tubing, a second tubing, and a cold plate assembly including a first channel to receive the first tubing and a second channel to receive the second tubing. A joint removably couples the first tubing to the second tubing and at least one component mounted on the cold plate assembly over the first tubing or the second tubing. The inlet end of the first tubing receives a cooling fluid and an outlet end of the second tubing discharges the cooling fluid after the cooling fluid flows through the first tubing, the joint, and the second tubing to maintain uniform a temperature of the at least one component mounted on the cold plate assembly.
