[0002] With the development of technology, people will place projectors in their bedrooms to replace traditional television equipment. As an important electronic projection instrument, the projector has the characteristics of small size, light weight and strong mobility. The temperature of the projector will be too high if used for a long time, which will affect its service life. Therefore, a projector internal heat dissipation structure is needed to assist in the heat dissipation of the projector.
