Definitions
- the housing 1 of this embodiment is a sealed structure, and the internal heat dissipation adopts an internal circulation air duct design.
- the dashed arrow in the figure is a schematic diagram of the route of the air duct.
- the cold air from the fan 3 blows to the polarization conversion module 2, taking away the heat on the polarization conversion module 2, and then exits the polarization conversion module 2.
- the hot air turns into cold air through the design of the heat dissipation fins 17 or the metal housing 1, and is sucked by the fan 3 and then blows to the polarization conversion module 2. This cycle is used to dissipate the polarization conversion module 2.
- the housing 1 of the polarization conversion system of this embodiment adopts a sealed design, which can increase the dust-proof effect, reduce noise pollution, and improve user experience.
- Providing the heat dissipation fins 17 on the housing 1 can increase the heat dissipation effect of the polarization conversion system and increase the service life of the polarization conversion system.
Abstract
L'invention concerne un système de conversion de polarisation comprenant : un boîtier (1) formant un espace de réception étanche, des ailettes de dissipation de chaleur (17) étant disposées sur le boîtier (1) ; et un module de conversion de polarisation (2) situé dans l'espace de réception. Par conséquent, la présente invention améliore l'effet anti-poussière du module de conversion de polarisation (2), et améliore les performances de dissipation de chaleur du système de conversion de polarisation, prolongeant ainsi la durée de vie du système. L'invention concerne en outre un projecteur.
