[0025] Please refer to Figures 1 to 5, a radiator for a replaceable heat dissipation fin projector in this embodiment, includes a projector body 1, a heat dissipation structure 2 disposed inside the projector body 1, and an optical engine bottom case 3 fixedly connected to the inside of the projector body 1. A heat sink assembly 4 is disposed outside the projector body 1. The heat sink assembly 4 includes a light-emitting lamp board 41 and a plurality of aluminum alloy heat sinks 42 disposed outside the light-emitting lamp board 41. By bonding the aluminum alloy heat sinks 42 to the light-emitting lamp board 41 with thermal conductive silicone, it is convenient to replace or clean them separately. The number of aluminum alloy heat sinks 42 can be increased or decreased according to actual heat dissipation requirements. By setting the heat dissipation structure 2, the heat dissipation efficiency of the light-emitting lamp board 41 is significantly improved. By setting the aluminum alloy heat sinks 42 in a circular arc bend design, strong light leaking from the air blowing ventilation 21 can be effectively blocked, and the user experience effect of the product can be significantly improved.

[0026] Among them, the light-emitting lamp board 41 is detachably connected to the inside of the projector body 1, and the aluminum alloy heat sinks 42 are bonded to the light-emitting lamp board 41 with thermal conductive silicone.

[0027] Specifically, a plurality of aluminum alloy heat sinks 42 are evenly distributed outside the light-emitting lamp board 41, and the aluminum alloy heat sinks 42 are designed in a circular arc bend. The air blowing channel 21 is fixedly installed inside the projector body 1, and the installation shell 22 is fixedly communicated with the outside of the air blowing channel 21.

[0028] It should be noted that the blower 23 is rotatably installed inside the installation shell 22, the dust-proof plate 24 is detachably connected to the outside of the installation shell 22, and the rotating shaft 25 is fixed to the axis of the blower 23 and extends to the outside of the dust-proof plate 24.

[0029] In this embodiment, a cleaning brush 26 that abuts against the outer surface of the dust-proof plate 24 is fixedly connected to one end of the rotating shaft 25 away from the blower 23. The outer diameter of the cleaning brush 26 is adapted to the diameter of the dust-proof plate 24. A rotating hole adapted to the rotating shaft 25 is opened inside the dust-proof plate 24, and the rotating shaft 25 is rotatably connected to the inside of the rotating hole. By starting the blower 23 to work through the controller to drive the rotating shaft 25 to rotate, the rotating shaft 25 drives the cleaning brush 26 to rotate to clean the dust-proof plate 24, avoiding dust accumulation, and at the same time, the aluminum alloy heat sinks 42 can be quickly dissipated, ensuring rapid heat conduction.

The optical engine bottom case 3 is located on the right side of the heat dissipation structure 2, and the heat sink assembly 4 is located on the right side of the optical engine bottom case 3.

[0031] The working principle of the above embodiment is as follows:

[0032] In use, the controller starts the blower 23 to work, driving the rotating shaft 25 to rotate. The rotating shaft 25 drives the cleaning brush 26 to rotate to clean the dust-proof plate 24. At the same time, it can quickly dissipate heat from the aluminum alloy heat sink 42. By setting the aluminum alloy heat sink 42 and the light-emitting lamp board 41 to be bonded with thermal conductive silicone, they can be replaced or cleaned separately. The number of aluminum alloy heat sinks 42 can be increased or decreased according to the actual heat dissipation requirements. By setting the aluminum alloy heat sink 42 as an arc-shaped curve, the stress points can be dispersed to reduce stress concentration.

Therefore, the specific structural composition and working principle will not be elaborated too much in this embodiment.
