摘要： A far-field radiative thermal rectification device uses a phase change material to achieve a high degree of asymmetry in radiative heat transfer. The device has a multilayer structure on one side and a blackbody on other side. The multilayer structure can consist of a transparent thin film of KBr sandwiched between a thin film of VO2 and a reflecting layer of gold. When VO2 is in its insulating phase, the structure is highly reflective due to the two transparent layers on highly reflective gold. When VO2 is in the metallic phase, Fabry-Perot type of resonance occurs and the tri-layer structure acts like a wide-angle antireflection coating achieved by destructive interference of partially reflected waves making it highly absorptive for majority of spectral range of thermal radiation. The instant structure can form the active part of a configuration that acts like a far-field radiative thermal diode.

摘要： A communication-type thermal conduction device includes a vapor chamber, at least one heat pipe, and at least one third capillary structure. The vapor chamber has a bottom board, and a first capillary structure is disposed on an inner surface of the bottom board. A second capillary structure is disposed in the heat pipe. One end portion of the heat pipe is connected to the bottom board, and the end portion has an open portion in communication with the heat pipe and the vapor chamber. The second capillary structure has a connected portion exposed by means of the open portion. The third capillary structure is connected to the first capillary structure and the connected portion, so that the first and second capillary structures are in communication with each other. Accordingly, holistic thermal conduction can be achieved, and the vapor chamber incorporating the heat pipe can provide the desired heat dissipation effect.
