Description
Technical field
The present invention relates to a kind of projector cooling device, relate in particular to a kind of projector's cooling device that uses solid state light emitter to arrange.
Background technology
The light source that general projector is used, as tungsten halogen lamp, metal halide lamp, ultrahigh pressure mercury lamp or xenon lamp etc., its common characteristic having is overheated, high power consumption, low bulb life, volume is excessive, weight is gently not portable again.Especially produce the part of high temperature, need to dispel the heat with plural cooling fan, to maintain the normal operation of this projector.In recent years, electronic product development is with the trend development of " light, thin, short, little, cost is low ", optical projector product is no exception, adopts at the Lights section the solid state light emitter that small volume and life-span grow, as light emitting diode (LED) or laser is used as light source.But, in projector, just light source does not have high heat generation, the optical module of other common runnings also has the generation of heat, for example, to produce digital micro-mirror device (the Digital Micro-mirror Device of projection image strip, DMD) in the time of running, also can produce heat, all need cooling device to dispel the heat, the effect of heat radiation is better will make the projection usefulness of projector better.The projector heat sink using at present is mainly divided into pyrotoxin light source and non-light source, the running that cooling fan dispels the heat is individually set respectively again, the heat abstractor of this class plural fan composition, is not only unfavorable for that the miniaturization of product but also cost height have again the problem of noise.So how to reduce the use amount of fan in the projector system that adopts solid state light emitter, and promote the radiating efficiency of projector, still need to study again improvement.
Summary of the invention
In view of this, be necessary to provide the projector's cooling device that can assist heat dissipation to promote.
The invention provides a kind of projector cooling device, it comprises a casing, a fan, a light source and an optical module, described fan is arranged in described casing and forms a radiating flow passage, described radiating flow passage is flowed through the inside of described casing with outside, described light source and described optical module are oppositely arranged and are close to described radiating flow passage in described casing, described light source and described optical module have respectively radiating subassembly setting, and described radiating subassembly is positioned at described radiating flow passage.
Compare prior art, projector of the present invention cooling device, inside and the described radiating flow passage of outside formation by described fan at described casing, the described radiating subassembly that described light source and described optical module are had is respectively positioned at described radiating flow passage, thereby can be simultaneously to the running of dispelling the heat of described projector heat generating component, can effectively promote the heat dissipation of described projector, and can reduce costs, quality that noise-decreasing improves described projector.
