Problems solved by technology

[0002] The imaging system of the projector is the core of the projector. If there is dust, soot and dust in the optical components or imaging components, it will cause contamination of the components, which will affect the contrast, color and service life of the projector.
Moreover, when the projector is working, it will also generate a large amount of heat, and the accumulation of heat will cause thermal deterioration of the projector and seriously reduce the imaging quality of the projected image.

Embodiment Construction

[0017] Such as Figures 1 to 3 As shown, the DLP projector liquid cooling system includes an optical body 100 and a sealing body 200 that seals the optical body 100 and conducts heat generated by the optical body 100 for heat dissipation.

[0018] The optical main body 100 is a DLP optical main body, which is a part that generates heat in the optical system of a DLP projector. The sealing body 200 includes a casing 220 and a heat dissipation device 240 , and the heat dissipation device 240 is arranged in close contact with the casing 220 . In one embodiment, the casing 220 includes a top cover 222 and a bottom cover 224 compatible with the top cover 222 , forming a receiving cavity compatible with the optical main body 100 inwardly to accommodate the optical main body 100 . Specifically, a gap matching the optical body 100 is provided in the housing 220, that is, the top cover 222 and the bottom cover 224 are respectively provided with a circular arc-shaped notch 2222 and a s...

Abstract

The invention relates to a liquid cooling and heat dissipating system for a digital light processing (DLP) projector. The system comprises an optical main body and a sealing member, wherein the sealing member is used for sealing the optical main body and conducting and dissipating the heat generated by the optical main body; the sealing member comprises a shell and a heat dissipating device; the optical main body is sealed by the shell; the heat dissipating device comprises a coolant pump, a cooling pipeline, a heat conducting plate and a heat dissipater; the heat conducting plate and the heat source of the optical main body are tigtly jointed; the heat conducting plate is connected with the heat dissipater through the cooling pipeline; and the coolant pump is arranged on the cooling pipeline. The liquid cooling and heat dissipating system for the DLP projector carries out heat exchange through the sealing member to quickly discharge the heat out of the DLP projector, so that the heat of the DLP projector can be quickly dissipated in the unpolluted environment to cool the DLP projector, thereby effectively ensuring the imaging quality.

Description

【Technical field】 [0001] The invention relates to a projection imaging device, in particular to a DLP projector liquid cooling system. 【Background technique】 [0002] The imaging system of the projector is the core of the projector. If there is dust, soot and dust in the optical components or imaging components, it will cause contamination of the components, thus affecting the contrast, color and service life of the projector. Moreover, when the projector is working, it will also generate a large amount of heat. The accumulation of heat will cause thermal deterioration of the projector and seriously reduce the imaging quality of the projected image. 【Content of invention】 [0003] Based on this, it is necessary to provide a DLP projector liquid cooling system that can prevent dust and lower the temperature. [0004] A liquid cooling heat dissipation system for a DLP projector, comprising an optical main body, and a sealing body that seals the optical main body and conduct...
