Problems solved by technology

[0002] In traditional projectors, the heat of the optical body is often generated by the core imaging components, and for these core imaging components, if the surface heat accumulates, the imaging quality of the projected image will deteriorate
In addition, light modulation devices such as liquid crystal panels have poor heat resistance, and may suffer thermal degradation due to heat generated by light beam irradiation from the light source device.
However, the cooling process of traditional projectors only sucks air from the outside, and blows in dust, oily smoke and dust, etc., which will cause pollution of projector components

Embodiment Construction

[0019] The projector includes an optical main body and a sealing body that seals the optical main body and conducts the heat generated by the optical main body to dissipate heat.

[0020] The optical body is any one of LCOS optical body, DLP optical body and LCD optical body. The optical body is the part of the projector optical system that generates heat.

[0021] The sealing body includes a housing and a heat dissipation device, the housing seals the optical main body, and the heat dissipation device is closely attached to the housing.

[0022] In another embodiment, the sealing body includes a housing and a heat dissipation device. A heat exchange hole matching the heat dissipation device is provided in the housing, and the heat dissipation device passes through the heat exchange hole and is arranged in close contact with the optical body.

[0023] In the first embodiment, figure 1 The detailed structure of a DLP projector is shown. In this embodiment, the optical body 10...

Abstract

The invention relates to a projector which comprises an optical main body, as well as a sealing body for sealing the optical main body and conducting heat generated by the optical main body. The projector can obtain rapid heat dissipation and cooling in an environment which is not polluted by carrying out heat exchange through the sealing body and rapidly discharging the heat to the outside of the projector, thereby effectively ensuring the imaging quality.

Description

【Technical field】 [0001] The invention relates to an image device, especially a projector. 【Background technique】 [0002] In a traditional projector, the heat of the optical body is often generated by the core imaging components, and for these core imaging components, if the surface heat accumulates, the imaging quality of the projected image will deteriorate. In addition, light modulation devices such as liquid crystal panels are poor in heat resistance, and may be thermally degraded due to heat generated by light beam irradiation from a light source device. However, the cooling process of traditional projectors is only to suck air from the outside, and blow in dust, oily smoke and dust, etc., which will cause pollution of projector components. 【Content of invention】 [0003] Based on this, it is necessary to provide a projector that avoids pollution to projector components and can dissipate heat. [0004] A projector includes an optical main body, and a sealing body t...
