As shown in fig. 1-2, the fluorescent wheel heat dissipation device of the present invention includes a sealed light source channel 100, a fluorescent wheel 130 disposed in a sealed cavity 120 of the sealed light source channel 100, a fluorescent wheel heat sink 200 disposed at a first side of the sealed light source channel 100, a light source heat sink 300 disposed at a second side of the sealed light source channel 100 near the light source 160 and the fluorescent wheel 130, and an exhaust fan 400 disposed at a side of the light source heat sink 300 remote from the sealed light source channel 100.
As further shown in fig. 2, the sealed light source channel 100 includes an aluminum housing 170 that forms the sealed cavity 120. The aluminum housing 170 is provided in a foreign rectangular shape with both sides closed, one side opened, the other side semi-closed, and an upper portion opened. Wherein the upper opening is provided with a light source channel cover 110. The light source channel cover 110 and the aluminum housing 170 are sealed by a silicone tape. A mounting plate 140 is provided on one side of the opening. The light source 160 is provided on the mounting board 140, and the light source 160 transfers heat to the light source heat sink 300 through the mounting board 140. The semi-enclosed side is provided with a light outlet 150. The light outlet 150 is sealed with a light-transmitting glass. The aluminum housing 170 is completely closed at a side facing the light outlet 150 and protrudes outward to form a sealing chamber 120, and the fluorescent wheel 130 is vertically disposed inside the sealing chamber. The light source heat sink 300 is provided in an L shape and is fitted to the outside of the outwardly convex side of the aluminum housing 170 so as to match the outwardly convex shape of the aluminum housing 170. The outside of the other closed side of the aluminum housing 170 adjacent to the installation of the light source heat sink 300 is installed with the fluorescent wheel heat sink 200.
As further shown in fig. 2, two exhaust fans are installed side by side on the side of the light source heat sink 300 remote from the sealed light source channel 100.
