Abstract
The invention relates to a cooling mechanism of a projector lamp bulb. The cooling mechanism of the projector lamp bulb comprises the lamp bulb (1). An air inlet (3) is formed in the tail of the lamp bulb (1). A vortex fan (2) is arranged on one side of the air inlet (3), a radiating air flue (4) is arranged on the periphery in the rear of the lamp bulb (1), the lamp bulb (1) is surrounded by the radiating air flue (4), a plurality of air outlets (6) are formed in the outer side of the lamp bulb (1), axial fans (5) are arranged on the inner sides of the air outlets (6), blind windows are arranged on the outer sides of the air outlets (6), and noise-abatement devices are arranged on the air inlet (3) and the air outlets (6). According to the cooling mechanism of the projector lamp bulb, the cooling effect of the projector lamp bulb is improved, and the noise produced during cooling of the projector lamp bulb is reduced.
Description
Technical field
The present invention relates to a kind of cooling body of projecting camera light bulb, belong to projector's technical field.
Background technology
Due to making rapid progress of science and technology, the application of projector is all the more extensive life with convenient people also.Common projector generally comprises housing and is arranged on photo engine, circuit board, apparatus for lighting up, light source and the corresponding cooling mechanism in housing.According to the number of camera lens used in photo engine, projector can be divided into single-lens projector and tri-lens projector again.Generally all that the white light first light source being produced is 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 modulation adopt diverse ways to process according to difference single-lens or three-lens design.In single-lens projector, be with closing that color component is synthesized and by single lens projection imaging by three coloured light.In tri-lens projector, be that three coloured light are projected to imaging on 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 larger, and the optical module such as the camera lens using and spectroscope is very high to the requirement of quality, precision, causes cost higher.And tri-lens projector can project larger picture in compared with short distance, picture brightness and contrast all improve a lot than single-lens projector.
Projector in the course of the work bulb can produce a large amount of heats, the energy of bulb is except a part becomes luminous energy, major part is distributed in projector with the form of heat, and these heats, as left not in time, can have a strong impact on the normal work and use life-span of projector.Therefore in projector, be all provided with cooling mechanism, generally establish the cooling body that has plenty of projecting camera light bulb.But in general projector, the cooling body radiating effect of bulb is not fine.
Chinese utility model patent instructions CN 101046611 A disclose a kind of like this mechanism for cooling projector bulb, this mechanism for cooling projector bulb comprises bulb heat radiation passage, vortex flow fan and aerofoil fan, bulb heat radiation air channel horizontally set is trapped among bulb wherein, its two ends are respectively equipped with air inlet and air outlet, air inlet is arranged on inner side, air outlet is arranged on outside corresponding to complete machine air outlet, vortex flow fan is arranged on air inlet side and is connected with air inlet provides cooling air intake, aerofoil fan is arranged on to be extracted wind out heat dissipation channel between air outlet and complete machine air outlet and discharges outside machine.The heat that the main thermal source of this invention mechanism for cooling projector bulb Neng Jiang projector distributes is discharged outside machine timely and effectively, reduced as much as possible it to the particularly heat affecting of liquid crystal board of the optical element in photo engine, greatly improved cooling effect, can the preserve value normal work of liquid crystal board, extends its serviceable life.But this mechanism for cooling projector bulb is not fine because air outlet only has one and air outlet to be arranged on bulb one side radiating effect, and can produce noise at work.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of cooling body of projecting camera light bulb, and the cooling body of this projecting camera light bulb has solved the problem that the poor and projecting camera light bulb of projecting camera light bulb cooling effect produces noise when cooling.
In order to solve the problems of the technologies described above, the cooling body of multi-projector bulb of the present invention, comprise bulb, bulb tail is provided with air inlet, and air inlet one side arranges vortex fan, bulb rear portion arranges heat dissipation wind channel around, heat dissipation wind channel is trapped among bulb wherein, and bulb outside is provided with several air outlets, and air outlet inner side is provided with aerofoil fan, air outlet arranged outside window shutter, arranges noise-abatement equipment on air inlet and air outlet.Adopt the cooling body of such projecting camera light bulb, because bulb outside is provided with several air outlets and aerofoil fan, the heat that bulb is produced that can be faster and better in projector's work discharges, and has improved and has discharged the efficiency of bulb heat and the serviceable life of bulb.Owing on air inlet and air outlet, noise-abatement equipment being set, can reduce the noise producing in discharging bulb heat process again.
Described air outlet is provided with two.Because bulb is not very large, two air outlets are set, saved resource.
Described noise-abatement equipment is silencing net.Silencing net is installed fairly simple, and soundproof effect is good.
Described vortex fan shell and aerofoil fan shell are provided with amortization sheet.Amortization sheet is installed more convenient, and soundproof effect is good.
Described amortization sheet is made by elastomeric material.Make simply, cost compare is low.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is the schematic diagram of the cooling body of projecting camera light bulb of the present invention.
Wherein have: 1. bulb; 2. vortex fan; 3. air inlet; 4. heat dissipation wind channel; 5. aerofoil fan; 6. air outlet.
Embodiment
The cooling body of projecting camera light bulb shown in Fig. 1 comprises bulb 1, bulb 1 afterbody is provided with air inlet 3, air inlet 3 one sides arrange vortex fan 2, bulb 1 rear portion arranges heat dissipation wind channel 4 around, heat dissipation wind channel 4 is trapped among bulb 1 wherein, bulb 1 outside is provided with several air outlets 6, air outlet 6 inner sides are provided with aerofoil fan 5, air outlet 6 arranged outside window shutters, on air inlet 3 and air outlet 6, silencing net is set, vortex fan 2 shells and aerofoil fan 5 shells are provided with amortization sheet, and amortization sheet is made by rubber.
Because conventional projecting camera light bulb volume and power are not very large, so the cooling body of projecting camera light bulb arranges two air outlets 6.On air inlet 3 and air outlet 6, silencing net is set, the noise of the cooling body that can further reduce projecting camera light bulb when work, at vortex fan 2 shells and aerofoil fan 5 case surface, be provided with amortization sheet, the vibrations and the noise that in the time of can further reducing work when vortex fan 2 shells and aerofoil fan 5 work, produce.When heat is discharged from air outlet 6, can by adjusting louver window, change the water conservancy diversion direction of air-out, further improve cooling effect.Arrow in Fig. 1 is from air outlet 6, to discharge the flow direction of heat.
The cooling body of projecting camera light bulb also can arrange a plurality of air outlets 6, and the heat that the number of air outlet 6 produces according to bulb goes to determine.
