Abstract
The utility model provides a projector bulb cooling device with a novel structure. The utility model comprises a bulb heat radiation duct, an eddy fan and an axial fan. The eddy fan is arranged at the side of air inlet, and the axial fan is arranged at the side of the air outlet; a sound damping fin is stuck on the sideface of the casing of the eddy fan. Because a sound damping fin is stuck on the sideface of the casing of the eddy fan in the projector bulb cooling device with a novel structure, the noise produced by the eddy fan is largely reduced and the overall quality and performance of the projector are improved.
Description
Technical field
The utility model relates to a kind of projector, relates in particular to a kind of mechanism for cooling projector bulb of new structure.
Background technology
Projector is widely used in education, commerce and the family.Common projector generally comprises a housing and is arranged on the interior photo engine of housing, circuit board, apparatus for lighting up, light source and corresponding cooling mechanism.According to what of camera lens used in the photo engine, projector can be divided into single-lens projector and tri-lens projector again.Generally all be earlier the white light that light source produced to be isolated red, green, blue three coloured light in design, by three liquid crystal light valves three coloured light are modulated respectively, three coloured light after the modulation are handled with diverse ways according to different mining single-lens or the three-lens design.In single-lens projector, be with closing that color component is synthesized and by the single lens projection imaging with three coloured light.In tri-lens projector, be that three coloured light are projected to imaging on the same screen via three different camera lenses respectively.Wherein single-lens projector has the advantages that volume is little, be convenient for carrying, but its back focal length is longer, and the bore of camera lens requires bigger, and optical modules such as employed camera lens and spectroscope are very high to the requirement of quality, precision, cause cost higher.And tri-lens projector can project big picture in than short distance, and picture brightness and contrast all improve a lot than single-lens projector.
Projector can produce a large amount of heat in the course of the work, and heat is mainly derived from bulb, the energy of bulb is except that a part becomes luminous energy, most of distribute in projector with the form of heat energy, these heats such as untimely leaving can have a strong impact on the operate as normal and the serviceable life of projector.Therefore in projector, all be provided with the heat radiation cooling body, comprise the lamp bulb cooling mechanism that is mainly used in the LCD cooling down mechanism that liquid crystal is cooled off and is used for bulb is cooled off.The heat radiation cooling body produces another problem again, i.e. noise when solving heat dissipation problem.A this noise part derives from the turnover wind eddies stream at air inlet and air outlet place, and a part derives from the vibration of blower-casting.Generally all there is either large or small noise in the mechanism for cooling projector bulb of prior art owing to its structural reason.
Summary of the invention
The purpose of this utility model is exactly in order to provide a kind of mechanism for cooling projector bulb of new structure.
The purpose of this utility model is achieved in that a kind of mechanism for cooling projector bulb of new structure, described projector comprises housing and is arranged on housing interior photo engine, circuit board, apparatus for lighting up, bulb and power supply and lamp bulb cooling mechanism, described lamp bulb cooling mechanism comprises bulb heat radiation air channel, vortex flow fan and aerofoil fan, vortex flow fan is arranged on the air intake oral-lateral, aerofoil fan is arranged on the air-out oral-lateral, and the amortization sheet is posted in the housing side of described vortex flow fan.
Described damping fin is the damping adhesive tape.
Described damping fin covers whole housing side.
Described damping fin is done and is sticked on the housing side into strips at interval.
The mechanism for cooling projector bulb of a kind of new structure of the utility model greatly reduces the noise that vortex flow fan produces owing to post the amortization sheet in the housing side of vortex flow fan, has improved the complete machine quality and the performance of projector.
