[0002] Outdoor micro projectors make traditional bulky indoor projectors more portable, miniaturized, entertaining and practical, bringing projection technology closer to outdoor life and entertainment. They have functions such as business office, teaching, outdoor entertainment, and are suitable for outdoor application scenarios.

[0003] However, outdoor projectors have difficulties in heat dissipation due to their high operating power, closed outer shell, and small internal space.

[0004] Outdoor projectors currently on the market are generally divided into aluminum extruded floodlights and die-cast floodlights based on their different heat dissipation mechanisms. The corresponding heat sinks used are aluminum extruded heat sinks and die-cast heat sinks, respectively. The projection end and power supply end are integrally located in the outer shell, but are separately located in different chambers.
