In one embodiment, the heat-dissipating coating is a thermally conductive silicone.

Specifically, the heat conductive silica gel has excellent heat conductivity, and can effectively conduct and disperse heat generated by the circuit board 30, thereby reducing the temperature of the circuit board 30 and reducing heat loss. The heat conducting silica gel is coated between the projector 40 and the circuit board 30, so that heat conduction from the projector 40 to the circuit board 30 can be accelerated, and then the heat is discharged through the heat radiating fan 50 and the heat radiating holes 13, and the overall heat radiating effect is improved. By maintaining a lower temperature, the thermally conductive silicone helps to protect the components on the circuit board 30 from damage caused by overheating. The heat conducting silica gel has excellent performance in high temperature environment, excellent stability and durability, and long-term stable heat dissipation performance.

Further, in manufacturing the circuit board 30 of the home projector 100, a layer of heat-conducting silicone is coated on a specific area of the circuit board 30, and is usually located at a heat dissipation portion of the circuit board 30. After hardening, the heat-conducting silica gel forms a firm heat-conducting layer, and is tightly combined with the circuit board 30, so that the heat conduction efficiency is improved. When the projector is operated, heat on the circuit board 30 is rapidly conducted to the heat dissipation fan 50 and the heat dissipation hole 13 region by the heat conductive silicone. The heat dissipation fan 50 discharges the hot air, and the heat dissipation holes 13 help to discharge heat from the inside of the projector, thereby maintaining a low operating temperature.
