Novel staggered plate fin heat sinks made of natural graphite sheets are presented and their performance is demonstrated via a direct comparison with aluminum. Measurements in a simple wind tunnel with a diode acting as a heat source show that the junction-to-ambient thermal resistance of the ...
Furthermore, the impact of contact sizes is smoothed out by the non-mathematically perfect heat source and sink areas. Indeed, in a theoretical system with a constant heat sink temperature at the ends of the bridge, contact areas would play an important role. But in the real experimental syst...
Further, a comparison between Examples 8 and 9 showed that a pressure should preferably be applied not only in a temperature region of not lower than 2400° C. but also in a temperature region of 1400° C. to 2400° C. Example 11 A polyimide film (thickness of 12.5 μm) similar to ...

For instance, a heat spreader may comprise a sheet which requires a maximum of thermal conductivity in the in-plane direction of the sheet (i.e., along the major surfaces of the sheet) in order to effectively spread heat as rapidly as possible. As a comparison, a gas diffusion layer (...
By comparison, aluminum 6061 has a density of 2.7 g/cm3and a thermal conductivity of ~180 W/mK, and copper has a density of 8.96 g/cm3and a thermal conductivity of ~400 W/mK. The material, therefore, matches the thermal performance of copper in two directions, at 15-22% of the weig...
Fundamental studies on the effects of graphite foam properties on boiling heat transfer subjected to different working fluids are still rather scarce. In this research, a compact thermosyphon with a graphite foaminsert was developed to conduct pool boiling experiments. A comparison of the boiling ...
