Does copper have high thermal conductivity
WebAs the demand for power density increases, so does the heat generated, which in turn causes the TIMs to adapt to higher ambient temperatures. As shown in Fig. 1 (a), when there is no TIM between the interface, it will be high thermal stress between the contact surfaces. Since the thermal conductivity of air is 0.0267 Wm −1 K −1, so it also … WebMar 8, 2024 · The thermal conductivity of copper varies two orders of magnitude at cryogenic temperatures. If you look at the figure in the link above from Jack Ekin’s book, RRR=2000 copper has a thermal conductivity at 10 K on par with the highest of diamond and sapphire. This thermal conductivity is a full 6!! orders of magnitude higher than …
