Embodiment
[0018] Embodiment: As shown in the figure, an LED heat sink includes a heat dissipation substrate 1 and a heat dissipation fin group 2. The heat dissipation fin group 2 includes a plurality of heat dissipation fins arranged at intervals on the top surface of the heat dissipation substrate 1, and two adjacent heat dissipation fins A heat dissipation channel 3 is formed between the fins, and the heat dissipation fins are parallel to the closed end of the heat dissipation substrate 1. One end of the plurality of heat dissipation fins on the same side extends out of the edge of the heat dissipation substrate 1. When the heat is transferred to the heat dissipation channel 3, the heat dissipation After the air in the channel 3 absorbs heat, its density decreases and rises to leave the heat dissipation channel 3, and the air with a lower temperature below the heat dissipation channel 3 outside the heat dissipation base 1 enters the heat dissipation channel 3, and it goes round and roun...
