Comparative testing of aluminum versus copper plates reveals a stark difference in heat dissipation efficiency; copper's thermal conductivity far exceeds what is apparent on the surface. Some manufacturers cut costs by using copper-plated aluminum plates to mimic solid copper structures, resulting in significantly compromised actual cooling performance. Truly effective thermal design requires a continuous and unobstructed thermal conduction path\u2014ideally extending the copper plate all the way to the device casing\u2014to achieve comprehensive thermal management. From the natural insulation of polar bear fur to engineered heat dissipation solutions..."}
