Abstract

The utility model discloses a heat dissipation structure of a portable miniature projector. The portable miniature projector comprises an imaging assembly used for projection and imaging and a movement box body used for a seal imaging assembly. One end of the imaging assembly is provided with a projection light source. An outer side of the projection light source is provided with a heat dissipation device. A periphery of the movement box body is connected with several heat conduction blocks through a fastener. The heat conduction blocks arranged on the periphery of the movement box body are used to release heat in the movement box body in real time so that a constant temperature working environment is created for the movement box body. During a heat conduction process, dust can be prevented from entering and derivation of static electricity can be avoided simultaneously.

Description

The radiator structure of portable minisize projector

Technical field

The utility model relates to projector equipment, and is relevant with portable DLP minitype projection machine, espespecially the radiator structure of minitype projection machine.

Background technology

progress along with shadow casting technique, the application of digital projector that can export high resolving power and large picture is more and more extensive, for making projector reach the requirement of high brightness and sharpness, usually use the light source of powerful bulb module as projector, yet the heat that produces during the work of high-power bulb module is very large, cause projector's internal temperature to raise rapidly, these heats are not in time discharged, the devitrification phenomenon at high temperature can occur in the quartz of shadow machine bulb inner wall, produce the spot of white, because the devitrification place stops light in a large number, this temperatures at localized regions is raise extremely, and then cause that the devitrification zone further enlarges, thereby brightness is decayed rapidly, and probably cause the bulb blast.In addition, it is too high that the physical property of the image-forming assembly of projector self has determined that its working temperature does not allow, in case its optics temperature surpasses its tolerance range, also can cause the damage of optical component.

Yet along with rise in Portable miniature projector market, its weight and profile are all constantly dwindled, cause heat-dissipating space also more and more less, cause heat in time to discharge, the work efficiency of projector will reduce, even can greatly shorten physical life, outside dust also easily enters projector inside by thermal window simultaneously, pollutes the internal imaging assembly.Static also can't in time be led and remove.Therefore micro projector has higher requirement to volume and the aspects such as layout and heat sink material of radiator structure.

Summary of the invention

The deficiency that exists in order to overcome prior art, the utility model provide the radiator structure of a kind of portable minisize projector, and this radiator structure can not only rapid heat dissipation, also has the effect of good dustproof and static.

To achieve these goals, the portable minisize of the present utility model projector following technical scheme of getting everything ready: comprise for the image-forming assembly of projection imaging and be used to sealing the movement casing of image-forming assembly, at image-forming assembly one end, be provided with projection light source, the outside in projection light source is provided with heat abstractor, and key point is that surrounding is connected with some heat-conducting blocks by securing member outside the movement casing.Such design be by depending on the outer surrounding of movement casing heat-conducting block by the heat in the movement casing in real time everywhere, give the working environment of building a constant temperature in the movement casing, in heat conduction, also can refuse the derivation with static that enters of dust.

In some embodiments, heat abstractor comprises aluminium sheet heat radiator body, fan and the blast hood that connects fan and aluminium sheet heat radiator body.

In some embodiments, heat-conducting block is that copper coin or aluminium sheet are made, and adopts screw or rivet to be fixedly connected with the movement casing.

In some embodiments, the height of heat-conducting block is identical with the movement box height.

Owing to adopting said structure, the utlity model has: compact conformation, easy to assembly, good heat dissipation effect and dustproof and static are a little.

Embodiment

With specific embodiment, the utility model is described in detail by reference to the accompanying drawings:

Refer to Fig. 1 to Fig. 5; The utility model discloses the radiator structure of a kind of portable minisize projector, this portable minisize projector 5 comprises; For the image-forming assembly of projection imaging and the movement casing 1 that prevents that be used to sealing image-forming assembly travel fatigue from entering, at image-forming assembly one end, be provided with projection light source, projection light source can produce a large amount of heats when work, these heats can be transmitted in movement casing 1, thereby cause the temperature of movement casing 1 to raise; Because movement casing 1 is sealing mechanism, heat can't in time be got rid of; In order to solve heat dissipation problem, the scheme that the utility model solves this technical matters is to be provided with heat abstractor in the outside of projection light source; Heat abstractor comprises the aluminium sheet heat radiator body 2 with multi-disc heat radiator, the blast hood 3 that fan 4 is installed and connects fan 4 and aluminium sheet heat radiator body 2 on aluminium sheet heat radiator body 2, by the heat that fan 4 produces projection light source timely, discharges.

In order to ensure that the image-forming assembly in seal cavity is not damaged by high temperature, is connected with some heat-conducting blocks 11 by securing member on the outer peripheric surface of movement casing 1.These heat-conducting blocks 11 adopt heat conductivility copper coin or aluminium sheet the best preferably; And adopt screw or rivet 110 to be fixedly connected with movement casing 1, in order to take less inner space, the height of heat-conducting block 11 is highly preferably identical with movement casing 1.Such design is by the heat-conducting block 11 that depends on movement casing 1 outer surrounding, the heat in movement casing 1 to be derived in real time, give the working environment of a constant temperature of the interior construction of movement casing 1, in heat conduction, also can refuse entering of dust, the heat-conducting block 11 of metal also can, timely and effectively by the derivation of static, have been guaranteed the normal operation of portable minisize projector 5.Owing to adopting said structure, the utlity model has: compact conformation, easy to assembly, good heat dissipation effect and dustproof and static are a little.

Having applied a concrete example herein sets forth principle of the present utility model and embodiment, the explanation of above embodiment is just in order to help to understand core concept of the present utility model, simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, this description should not be construed as restriction of the present utility model in sum.
