Abstract

The invention provides a projector, which comprises a shell with an accommodating space and a radiator fixed in the accommodating space. The shell comprises a plurality of shutter structures penetrating through the shell, and the radiator comprises a plurality of radiating fins which are mutually overlapped and parallelly arranged at intervals. The ends, abutting against the shell, of the multiple cooling fins jointly form an air outlet face, the ends, away from the air outlet face, of the multiple cooling fins jointly form an air inlet face, and the air outlet face abuts against the shell and completely covers the shutter structure. And the accommodating space is communicated with the outside through the radiator and the shutter structure in sequence. Compared with the prior art, the projector meets the DCI authentication requirement, the ventilation condition is good, the system heat dissipation performance is good, and noise is low.

Description

【Technical field】 [0001] The invention relates to the technical field of projectors, in particular to a projector conforming to DCI certification. 【Background technique】 [0002] With the continuous improvement of people's living standards, the projection quality and confidentiality requirements of projectors in movie theaters are also getting higher and higher. Projectors that meet the digital copyright unique identifier (DigitalCopyright Identifier, DCI for short) certification requirements are becoming more and more important. Among them, the heat dissipation structure of the projector is an important part. [0003] The heat dissipation structure of the projector in the related art includes a casing and a radiator connected to the casing. [0004] However, in order to meet the anti-tampering regulations required by the DCI certification, the current projector is configured with a labyrinth structure in the casing connected to the heat sink. The maze structure can block...
