Technical field
The utility model belongs to the liquid crystal projector technical field, specifically is a kind of color separation-combination system heat abstractor of light engine of the LCOS of being used for liquid crystal panel.
Background technology
At present, the light engine of LCOS liquid crystal panel often adopts PBS or X prism as color separation/close look parts, PBS or X prism constitute the color separation-combination system of light engine with LCOS liquid crystal panel, quarter wave plate, compensating plate etc., the LCOS liquid crystal panel with the optical imagery on it by projection lens projects to screen or on the catoptron.
Because LCOS liquid crystal panel volume is little, adds that the operating characteristic of its reflection causes the heat of its absorption big, causes LCOS liquid crystal panel temperature height.One of physical property of LCOS liquid crystal panel self is that resistance to elevated temperatures is poor, in case temperature surpasses its tolerance range, can cause the cause thermal damage of LCOS liquid crystal panel, has a strong impact on the life-span of LCOS liquid crystal panel.Same PBS itself also has temperature limitation, and when the temperature of PBS or X prism was too high, the operating characteristic of the film that can influence on the PBS to be plated directly caused the image quality problem.Quarter wave plate and compensating plate also have temperature limitation in addition.
The heat abstractor of the color separation-combination system of traditional optical engine adopts the mode of forced convertion or natural convection, by direct liquid coolant crystal panel of air or the heat radiator that is connected with liquid crystal panel, PBS or X prism, quarter wave plate, compensating plate etc. also all adopt the cross-ventilation radiating mode to cool off, and radiating effect is not good; Because of the big factor of flow passage resistance force of waterproof, the noise that fan produces is big; The optical device of the color separations such as causing the LCOS liquid crystal panel easily of flowing of air/close colour system system adheres to dust, has a strong impact on image quality.
Summary of the invention
The purpose of this utility model provides that a kind of good heat dissipation effect, noise are low, the color separation-combination system heat abstractor of the light engine of the LCOS liquid crystal panel of color separation-combination system free from dust.
Originally the color separation-combination system heat abstractor that is used for the light engine of LCOS liquid crystal panel is following realization.It comprises: the opticator with at least one LCOS liquid crystal panel, some PBS or X prism and condenser etc., supporter, heat transmission aerofoil fan, the heating radiator of some PBS or X prism and the fixed head that described LCOS liquid crystal panel is installed are installed, aerofoil fan is fixed on the heating radiator, each LCOS liquid crystal panel is arranged on the fixed head, and all fixed heads connect a heat pipe respectively to heating radiator; Also can be connected another heat pipe between the supporter of described heating radiator and PBS or X prism, the joint gap place of the supporter of PBS or X prism and some PBS or X prism is filled with thermal grease.
The utility model adopts the radiator structure of some heat pipes and heating radiator combination, can make the temperature of optics LCOS liquid crystal panel, PBS or the X prism etc. of light engine color separation-combination system obviously descend the radiating effect ideal.
Housing with sealing, each optics can not adhere to dust in the heat radiation process, obviously descended by the noise that fan produced.
