    Abstract: Novel 3-D super-thermal conducting heat management design and delayed cooling using phase change materials are adopted to lower the temperature inside LEDs and other devices. The cooling mechanism uses a fin structure with hollow fins to dissipate heat to the environment. The hollow space inside the fins is connected to an interior chamber, where a liquid to vapor phase change material (L-V PCM) is provided to transfer heat from the LED chips to the surface of the hollow fins. The LED chips are mounted on an evaporator located at the bottom of the chamber. A liquid reservoir is provided, and the evaporator surface is hydrophilic with an additional wick structure to transport the L-V PCM liquid to the evaporator surface. The fins are parallel to each other and are either parallel or perpendicular to the evaporator surface. This structure has superior performance and is inexpensive to manufacture.

    Abstract: A high-throughput combinatorial materials experimental apparatus for in-situ synthesis and real-time characterization includes a composition spread device to prepare continuous or discrete composition distribution as precursor of the high-throughput experimental samples library, a low temperature diffusion mixing device to thoroughly mix the composition spread in the thickness direction through diffusion at a relatively low temperature to form an amorphous precursor, and an integrated synthesis-characterization unit for heat treatment of the material library precursor in either a parallel or point-by-point scanning mode at different thermodynamic conditions for phase formation and to characterize features or properties of the materials of interest in an in-situ and real-time manner. The integrated synthesis-characterization unit includes a chamber maintained at desired vacuum and atmosphere, a micro-heating source, an excitation source, a signal collector, and a sample holder.

    Abstract: A mechanism for cooling the anode of an x-ray tube using a phase change material to transfer heat away from the anode. The x-ray tube is joined to a sealed heat exchange chamber which contains a liquid metal as a liquid to vapor phase change material (L-V PCM). The back side of the anode is exposed to an interior of the heat exchange chamber, and a jet sprayer inside the heat exchange chamber sprays a liquid of the metal onto the back side of the heated anode. The L-C PCM evaporates on that surface to carry away the heat, and the vapor then condenses back into the liquid on the cool surfaces of the heat exchange chamber. The surfaces of the heat exchange chamber may be cooled by convection cooling. Optionally, pipes containing a circulating cooling fluid may be provide inside the heat exchange chamber.
