It is widely recognized that copper's thermal conductivity is significantly higher than that of aluminum. Consequently, some people assume that heat sinks made of copper must be superior to those made of aluminum. However, the effectiveness of a heat sink is influenced not only by the material's thermal conductivity but also by factors such as the heat dissipation surface area, the heat sink's design, and airflow conditions.

    While copper's thermal conductivity surpasses that of aluminum, offering reduced resistance to heat flow from the source to the environment, its greater heat capacity and slower temperature rise within the same volume lead to a minimal temperature gradient. Consequently, its overall heat transfer capability is not notably superior to that of aluminum.

    It is essential to recognize that in high-power applications such as frequency converters, inverters, welding machines, SVG, APF, and energy storage systems, the selection of heat sinks involves considering various aspects, including cost, manufacturing process, and cost-effectiveness. Pure copper is excessively priced and challenging to process, resulting in low cost-effectiveness and ruling it out as a mainstream option. Consequently, aluminum profile heat sinks are the preferred choice for cooling these devices.
