According to a study published in the Journal of Materials Science, materials with high thermal conductivity, such as copper and aluminum, are essential for effective heat sinks because they facilitate rapid heat transfer, ensuring that the temperature of the component remains within safe operating limits (Liu et al., 2020).
The underlying mechanism involves the atomic structure of materials; metals like copper have free electrons that can move quickly, allowing heat to flow efficiently. When a heat sink is attached to a device like the Raspberry Pi 3, the heat generated by the processor is conducted through the heat sink material. If the material has low thermal conductivity, it will not effectively carry heat away, leading to hotspots and potential thermal throttling, which can impair performance (Parker et al., 2019). Additionally, the surface area and geometry of the heat sink also play a role in enhancing heat dissipation by increasing the contact area with air, promoting convection and further aiding in cooling efficiency.
