The inner heat sink 201 directly contacts the heat-generating components such as the rectifier bridge to absorb heat; the outer heat sink 202 dissipates heat into the environment through air convection and other means.

This heat is first absorbed through the inner heat dissipation slots 201 of the heat sink 2 and then transferred along the wall of the heat sink to the outer heat dissipation slots 202. Simultaneously, the presence of the heat dissipation fins 3 further increases the heat dissipation area and accelerates airflow, thus more effectively removing heat. The through-holes 203 between the inner and outer heat dissipation slots 201 and 202 ensure smooth heat transfer within the heat sink. Finally, the heat is dissipated to the external environment through the outer heat dissipation slots and fins, achieving effective heat dissipation for the rectifier bridge. The entire heat dissipation process is efficient and stable, ensuring the normal operation and long-term reliability of the automotive alternator.

Simultaneously, the presence of the heat dissipation fins 3 further increases the heat dissipation area, thus more effectively removing heat. The through-holes 203 between the inner and outer heat dissipation slots 201 and 202 ensure smooth heat transfer within the heat sink 2.
