It’s used for all-in-one PC. Different metal-binding technology, combined with heat pipes and fin heat sink to reach to the thin design, so that the whole design could be thinner and smaller.
Welding of dissimilar metals(Joining of different metals) technology, mainly due to the slow thermal conductivity of aluminum alloy, it will be designed to apply heat pipes or copper base of heat sinks to increase the thermal dissipation efficiency, there are two ways
A technique alloyed with other metals- fins are attached to the heat sink base, heat will be generated to the fins from the base.
Aluminum Extrusions:1.Thermal solution:Aluminum extrusions is one of the most common material used in developing heat dissipation solutions. When the cooling is completed, the extruded aluminum is treated with mechanical finishing: precision cutting, punching, crosscutting
Friction-stir welding (FSW) is a solid-state joining process (the metal is not melted) that uses a third body tool to join 2 faying surfaces. Heat is generated between the tool and material which leads to a very soft region near the FSW tool.
