Description
Technical field
The utility model relates to projector field, in particular to cycle refrigeration system in a kind of electronic projection apparatus.
Background technique
Electronic projection apparatus is internally provided with a large amount of optical device, due to a generally sealing structure, each optics
The a large amount of heat that can be generated when device use, and these heat generally only fan radiates, fan cooling efficiency is very low.
And if optical device cannot radiate in time, will lead to internal heat it is excessively high and the case where damage optical device, cause entirely to throw
The service life of shadow instrument reduces.The dust in air that fan is blown into simultaneously can be sticked on optical device, over time can be serious
Influence drop shadow effect.
Summary of the invention
The technical problem to be solved by the utility model is to provide cycle refrigeration systems in a kind of electronic projection apparatus, have non-
Often good cooling system quickly reduces optical device temperature by semiconductor chilling plate using the refrigeration structure of air-conditioning, reaches high
Effect heat dissipation.
The utility model is achieved through the following technical solutions: cycle refrigeration system in a kind of electronic projection apparatus, packet
A seal casinghousing is included, interior optics are incorporated with inside seal casinghousing, are provided with one at the top of the interior optics
Refrigeration radiating system, the refrigeration radiating system include a fan, heat-conducting block, semiconductor chilling plate and cool guiding block, the system
One lens assembly is installed on the side seal casinghousing of cold cooling system；
The heat-conducting block is installed on the heating surface of semiconductor chilling plate, and fan is installed on the outside of heat-conducting block, cool guiding block installation
Interior optics are faced in the cold air output end of the chill surface of semiconductor, cool guiding block.
As a preferred technical solution, the interior optics include light cone, the first luxuriant and rich with fragrance mirror, LCD screen, the second luxuriant and rich with fragrance mirror with
And reflective mirror, it is mounted on inside seal casinghousing.
A heat shield is installed between the described first luxuriant and rich with fragrance mirror and LCD screen as a preferred technical solution,.
The beneficial effects of the utility model are: all optical devices are packed into one by the electronic projection apparatus of the utility model
Seal casinghousing, internal heat is gone by semiconductor chilling plate export, then is dissipated with fan, reaches high efficiency and heat radiation, simultaneity factor
Inside can form a dustless space, and internal optical device is allowed to remain completely solve conventional projector use
Easily occurs the problem of dirty point, stain after a period of time.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is the overall structure diagram of the utility model.
Specific embodiment
All features disclosed in this specification or disclosed all methods or in the process the step of, in addition to mutually exclusive
Feature and/or step other than, can combine in any way.

Body cooling piece 3 and cool guiding block 4 are equipped with a lens assembly 12 on the side seal casinghousing of refrigeration radiating system；
Heat-conducting block 2 is installed on the heating surface of semiconductor chilling plate 3, and fan 1 is installed on 2 outside of heat-conducting block, cool guiding block installation
In the chill surface of semiconductor chilling plate 3, the cold air output end of cool guiding block 4 faces 11 interior optics of seal casinghousing.
In the present embodiment, interior optics include the luxuriant and rich with fragrance mirror 6 of light cone 5, first, the luxuriant and rich with fragrance mirror 9 of LCD screen 8, second and reflective mirror
10, it is mounted on inside seal casinghousing 11, a heat shield 7, interior optics is installed between the first luxuriant and rich with fragrance mirror 6 and LCD screen 8
For any technique commonly known structure, its working principle and positional structure are not repeated specifically herein.
In use, the heat that semiconductor chilling plate generates leads hull outside by heat-conducting block, then dissipated rapidly with fan
The cold air of heat, generation leads enclosure interior, cooling interior optics by cool guiding block.
The beneficial effects of the utility model are: all optical devices are packed into one by the electronic projection apparatus of the utility model
Seal casinghousing, internal heat is gone by semiconductor chilling plate export, then is dissipated with fan, reaches high efficiency and heat radiation, simultaneity factor
Inside can form a dustless space, and internal optical device is allowed to remain completely solve conventional projector use
Easily occurs the problem of dirty point, stain after a period of time.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
In this, any change or replacement expected without creative work be should be covered within the scope of the utility model.
Therefore, the protection scope of the utility model should be determined by the scope of protection defined in the claims.
