Embodiment Construction

[0013] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0014] see figure 1 As shown, it is a schematic diagram of an embodiment of the optical-mechanical cooling device for a projector of the present invention. The cooling device 10 includes a housing 12 , a fan module 14 , an optical-mechanical module 16 and a cooling module 18 . The optical-mechanical module 16 is arranged in the housing 12, and the optical-mechanical module 16 includes a light source 161, a light combination device 162, a light guide assembly 163, a prism group 164, and a digital micromirror display device 165 And a projection lens group 166. The light source 161 is mainly used to generate three primary colors of light, namely red light, blue light and green light. The three primary color lights are combined into a combined light beam on the same optical axis by the light combining device 162, and then the combined light beam of the three color ligh...

Abstract

The invention provides a cooling device for an optical machine of a projector. The cooling device for the optical machine of the projector comprises a casing, a fan module, an optical machine module and a cooling module. The optical machine module is arranged in the casing and connected with the cooling module, the cooling module is located on the outer side of the casing, a fan flow channel is arranged on the outer side of the casing, and the fan module is arranged in the fan flow channel. Air flow generated by the fan module is lead by the fan flow channel to face the cooling module. The fan module is arranged in the fan flow channel on the casing of the optical machine module, cooling effect of the optical machine of the projector is improved, and cost is reduced.

Description

technical field [0001] The invention relates to an optical-mechanical cooling device for a projector, in particular to an optical-mechanical cooling device for a projector with a fan flow channel in the optical-mechanical casing. Background technique [0002] The light sources used in general projectors, such as tungsten-halogen lamps, metal halide lamps, ultra-high pressure mercury lamps, xenon lamps or light-emitting diodes (LEDs), laser light sources, etc., have a common characteristic of generating high heat. The high heat must be removed through the cooling device, otherwise it will affect the normal operation of the projector. At present, the heat dissipation device of the projector is usually provided with several cooling fans matched with each other on the casing of the projector, and a corresponding air duct is installed in the casing with respect to the setting of the fans, so that by all The air guide pipe guides the cooling airflow to flow through the light sour...
