Abstract
The utility model relates to a new pattern bulb cooling device for a projector which comprises a bulb thermal air channel, an axial-flow fan and a sound-deadening air channel, wherein the bulb is surrounded by the bulb thermal air channel whose both ends are provided with an air inlet and an air outlet separately, the axial-flow fan is arranged between the air outlet of the bulb thermal air channel and the air outlet of the body, the sound-deadening air channel is arranged between the air outlet of the thermal air channel and the axial-flow fan, both ends of the sound-deadening air channel are connected with the air outlet of the thermal air channel and the axial-flow fan separately. The new pattern bulb cooling device for a projector of the utility model is provided with the sound-deadening air channel between the air outlet of the bulb thermal air channel and the axial-flow fan, thereby can greatly decrease the noise produced when the cooling air flows through the body and advance the quality and property of the whole body of the projector.
Description
Technical field
The utility model relates to a kind of projector, relates in particular to a kind of New Projection Display lamp bulb cooling mechanism.
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 air inlet of fan and the turnover wind eddies stream at air outlet place, and a part derives from the vibration of heat dissipation wind channel housing.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 New Projection Display lamp bulb cooling mechanism.
The purpose of this utility model is achieved in that a kind of New Projection Display lamp bulb cooling mechanism, described projector comprises housing and is arranged on the interior photo engine of housing, circuit board, apparatus for lighting up, light source and lamp bulb cooling mechanism, housing is provided with complete machine air inlet and air outlet, described lamp bulb cooling mechanism comprises bulb heat radiation air channel and aerofoil fan, the bulb heat radiation air channel is trapped among bulb wherein, its two ends are respectively equipped with air inlet and air outlet, aerofoil fan is arranged between the air outlet and complete machine air outlet in bulb heat radiation air channel, also comprise the noise elimination air channel of making by deadener, this noise elimination air channel is arranged between the air outlet and aerofoil fan of heat dissipation wind channel, and its two ends link to each other with the air outlet and the aerofoil fan of heat dissipation wind channel respectively.
A kind of New Projection Display lamp bulb cooling mechanism of the utility model is owing to be provided with the noise elimination air channel between the air outlet in bulb heat radiation air channel and aerofoil fan, thereby greatly reduce the noise that is produced when cooling air flows through in the body, improved the complete machine quality and the performance of projector.
Description of drawings
Fig. 1 is the primary structure synoptic diagram that has the projector of a kind of New Projection Display lamp bulb cooling mechanism of the utility model.
Embodiment
A kind of New Projection Display lamp bulb cooling mechanism of the utility model is arranged in the housing of projector, and the bulb that is mainly used in being installed in the housing cools off, and its heat that distributes is in time discharged outside the machine.
Referring to Fig. 1, Fig. 1 is the primary structure synoptic diagram that has the projector of a kind of novel light bulb cooling body of the utility model.Shown in the figure, 1 is projector's housing, and 11 for being arranged on the complete machine air inlet on the housing, and 12 for being arranged on the complete machine air outlet on the housing, and 2 is that photo engine, 3 is light source.Lamp bulb cooling mechanism in the utility model comprises bulb heat radiation air channel 4, aerofoil fan 5 and noise elimination air channel 6.Bulb heat radiation air channel 4 is trapped among light source 3 wherein, its two ends are respectively equipped with air inlet 41 and air outlet 42, wherein air inlet 41 is arranged on a side in bulb heat radiation air channel 4 corresponding to complete machine air inlet 11, air outlet 42 is arranged on the opposite side in bulb heat radiation air channel 4 corresponding to complete machine air outlet 12, aerofoil fan 5 is arranged on to be extracted wind out the bulb heat radiation air channel between the air outlet 42 in bulb heat radiation air channel 4 and the complete machine air outlet 11 and discharges outside machine, noise elimination air channel 6 is arranged between the air outlet 42 and aerofoil fan 5 of heat dissipation wind channel, and its two ends link to each other with the air outlet 42 and the aerofoil fan 5 of heat dissipation wind channel respectively.Noise elimination air channel 5 is made by deadener, and this deadener can be a rubber, also can be that acrylic acid damping material or other have the material of noise elimination effect.
