Problems solved by technology

Therefore, the projector is in shutdown or standby mode most of the time. At this time, the machine does not need to perform alternate cooling actions of internal and external airflow. Therefore, dust and other pollutants may gradually enter the preset cooling air inlet and outlet. , which has a great impact on the life of the machine

Embodiment Construction

[0031] In order to make the objects, technical solutions, and advantages of the present invention, the technical solutions of the present invention will be apparent from the accompanying drawings, which will become apparent from the accompanying drawings. Embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art are in the range of the present invention without making creative labor premise.

[0032] Currently, the heat sink structure of the pressing door buckle is generally used for the heat dissipation device of the projection device. The filter replacement can be replaced without the use of other auxiliary tools to block the contamination of the outer dust on the projection equipment.

[0033] The quick release structure has strong convenience, but the machine of the projection device is not in operation, and the inside of the machine will be affected by other pollutants such as dust. And this structure ...

Abstract

The invention provides a heat dissipation device and a projector, and relates to the technical field of heat dissipation application. The heat dissipation device comprises a fan, a dustproof sheet and a torsion spring, wherein the dustproof sheet is arranged on one side of the fan, and the torsion spring is arranged on the dustproof sheet; the fan runs to generate wind power; the dustproof sheet is driven by wind power to rotate and form an opening and closing angle with the initial direction of the dustproof sheet; and the torsion spring drives the dustproof sheet to rotate to the initial direction of the dustproof sheet under the condition of no wind power. By arranging the dustproof sheet of which the opening and closing angle can be changed, the projector can be protected from being invaded by other pollutants such as dust when not working, and the basic heat dissipation requirement can be ensured when a machine table works.

Description

Technical field [0001] The present invention relates to the field of heat dissipation applications, and more particularly to a heat sink and a projector. Background technique [0002] In a projector's market environment, depending on the diverse of different projectors in the application place, the long working downturn is different, but the length of the machine's work will not exceed eight hours per day. Therefore, the projector is in a shutdown or standby mode at most, and the machine at this time does not need to perform internal and external airflow alternating heat dissipation. Therefore, in the preset heat dissipation, the air outlet may gradually enter other contaminants. This has a great impact on the life of the machine. Inventive content [0003] It is an object of the present invention to provide a heat dissipation device and a projector, by setting a dustproof piece that can change the opening and closing angle, protecting other contaminants from dust when the proje...
