Abstract
The utility model provides a projector bulb cooling mechanism comprising a bulb heat dissipating duct, a vortex flow fan and an axial flow fan. The bulb heat dissipating duct is transversely arranged to surround a bulb and the two ends of the bulb heat dissipating duct are respectively provided with an air outlet and an air inlet which is arranged at the inner side while the air outlet is arranged at the outer side and corresponds to the air outlet of the whole machine. The vortex flow fan is arranged at the side of the air inlet and is connected with the air inlet to provide cooling air. The axial flow fan is arranged between the air outlet and the air outlet of the whole machine to exhaust air out of the machine after extracting air from the heat dissipating duct. The heat, which is emitted by the main heat source of the projector, can be effectively exhausted out of the machine in time by the projector bulb cooling mechanism of the utility model, and the heat influence on an optical element, especially a liquid crystal panel of an optical engine is reduced as much as possible, so the projector bulb cooling mechanism of the utility model greatly improves cooling effect, ensures the normal work of the liquid crystal panel and prolongs the service life.
Description
Technical field
The utility model relates to a kind of projector, relates in particular to a kind of mechanism for cooling projector bulb.
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, make a noise by three liquid crystal light respectively three coloured light are modulated, 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 factory of camera lens directly 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 cooling mechanism, be used for the heat that the course of work produces is in time left, this cooling mechanism generally comprises many fans that vary in size and corresponding wind channels, be used for sucking force air at work from the outside and ventilate, heat is in time discharged from air outlet.
The utility model content
The technical problems to be solved in the utility model provides a kind of heat that main thermal source distributed of projector can the discharge outside the machine timely and effectively, has improved cooling effect greatly, can guarantee the lamp bulb cooling mechanism of the operate as normal of liquid crystal board.
For solving above technical matters, a kind of mechanism for cooling projector bulb of the present utility model, comprise housing and be arranged on housing interior photo engine, circuit board, apparatus for lighting up, bulb and power supply, on housing, be provided with the complete machine air outlet, an independent modified lamp bulb cooling mechanism that is provided with, described modified lamp bulb cooling mechanism comprises bulb heat radiation air channel, vortex flow fan and aerofoil fan; Described bulb heat radiation air channel horizontally set is trapped among bulb wherein, and its two ends are respectively equipped with air inlet and air outlet; Described air inlet is arranged on the inboard, and air outlet is arranged on the outside corresponding to the complete machine air outlet; Described vortex flow fan is arranged on the air intake oral-lateral and links to each other with air inlet; Described aerofoil fan is arranged between air outlet and the complete machine air outlet.
Described bulb heat radiation air channel air outlet is provided with the light that stops bulb and drains to shutter outside the projector.
The distance of described bulb heat radiation air channel air outlet and aerofoil fan is not less than 10 millimeters.
Between described bulb heat radiation air channel air outlet and the aerofoil fan wind output channel is arranged, this wind output channel can be totally-enclosed air channel or partially enclosed air channel.
The advantage of the utility model mechanism for cooling projector bulb is: because this cooling body is provided with radiator fan and heat dissipation wind channel at bulb specially, thereby discharge the heat that main thermal source distributed of projector outside the machine timely and effectively, reduced it as much as possible to the particularly heat affecting of liquid crystal board of the optical element in the photo engine, improved cooling effect greatly, can guarantee the operate as normal of liquid crystal board, prolong its serviceable life.
Description of drawings
Figure is a structural representation of the present utility model.
Embodiment
The utility model mechanism for cooling projector bulb 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.
As shown in the figure, 1 is projector's housing, and door is for being arranged on the complete machine air outlet on the housing, and 2 is that photo engine, 3 is bulb.The utility model lamp bulb cooling mechanism comprises bulb heat radiation air channel 4, vortex flow fan 5 and aerofoil fan 6, bulb heat radiation air channel 4 horizontally sets are trapped among bulb 3 wherein, its two ends are respectively equipped with air inlet 41 and air outlet 42, wherein air inlet 41 is arranged on the inboard in bulb heat radiation air channel 4, air outlet 42 is arranged on the outside in bulb heat radiation air channel 4 corresponding to complete machine air outlet 11, on air outlet 42, be provided with shutter, drain to outside the projector with the light that stops bulb.Vortex flow fan 5 is arranged on the air intake day side and link to each other with air inlet 41 the cooling air intake is provided in bulb heat radiation air channel 4, aerofoil fan 6 is arranged on the air outlet 42 in bulb heat radiation air channel 4 and extracts wind out the bulb heat radiation air channel between complete machine air-out day 11 and discharge outside machine, aerofoil fan 6 and the distance between bulb heat radiation air channel air-out day 42 are not less than 10 millimeters, to guarantee fan efficiency.At aerofoil fan 6 and between bulb heat radiation air channel air-out day 42 wind output channel 7 can also be set, come out from the bulb heat radiation air channel to guarantee the wind that aerofoil fan is discharged.This wind output channel 7 can be totally-enclosed air channel, also can part not seal, and the purpose of not sealing is and the hot-air of his part in the machine can be discharged.
