In a CPU heatsink, what is the best combination of copper and aluminum to extract heat away from the processor effectively, without having cost be a factor? A few claims: Copper has a higher thermal conductivity, and therefore is superior to aluminum in processor cooling. Copper is better...
Remember that discussion about how heat can only flow from a higher temperature source to a lower temperature sink. And also, the heat starts at the circuit junction level and continues to the outside air where it is finally rejected. Every time there is a heat transfer from one source...

High Thermal Conductivity Materials: Aluminum Diamond, Aluminum Silicon Carbide, and Copper DiamondThe superior heat dissipation characteristic of diamond reinforced metal matrix composites has started to demonstrate significant performance advantages in RF Amplifier designs especially when heat di...
The method used to bond thecopper layerto the aluminum base through the dielectric layer affects thermal performance: Direct Bonding: Offers excellent thermal conductivity but is more expensive Thermal Lamination: More common, balances cost and performance ...
The unfinished surface of aluminum can be measured at an emissivity of approximately 0.05, while the emissivity of an anodized aluminum surface can be measured at around 0.85. In this condition, what would be the correct # for the thermal conductivity of AL5052 black-anodized power supply ...
The thermal conductivity and volume resistivity of a composition obtained by pressing copper and aluminum micro(nano)powders with subsequent sintering is estimated in terms of an integrated medium theory. Similar composite materials can find use as heatsinks for high-power transistors and diodes.关键...
