As electronic devices become more powerful and compact, the need for efficient cooling becomes increasingly important. One of the most effective solutions is to use folded-fin heatsinks, especially those made of copper. Folded fin heat sinks have become popular in the electronics industry due to their ability to increase the surface area for heat dissipation. Copper is a common material for this type of heat sink because of its high thermal conductivity, which allows heat to be transferred away from critical components quickly and efficiently.
