Description
Technical field
The present invention relates to high-pressure sodium lamp technical field, more particularly, to a kind of heat abstractor of high pressure mercury lamp of projector.
Background technology
In projector's manufacturing technology, it is often necessary to using up to upper kilowatt or more power high-pressure sodium lamp light source, it is higher
The light source of power means bigger exposure yield, is conducive to improving the manufacture efficiency of projector.In order to ensure the normal of light source
Operating temperature to high-pressure sodium lamp fluorescent tube, it is necessary to cool down.Traditional high-pressure sodium lamp fluorescent tube has first end, wick and second
The heat that the second end is produced in end, fluorescent tube is more, and traditional high-pressure sodium lamp cooling device is that whole high-pressure sodium lamp is cooled down,
There is no that the radiating in specific aim, fluorescent tube at the second end is not thorough, radiating effect is poor, is easily caused burning for whole fluorescent tube, shadow
Ring the service life of the projector for using and using the high-pressure sodium lamp to be made of high-pressure sodium lamp.
The content of the invention
The technical problem to be solved in the present invention is：In order to overcome traditional high-pressure sodium lamp cooling device to be to whole high-pressure mercury
Lamp is cooled down, without specific aim, and the radiating in fluorescent tube at the second end is not thorough, and radiating effect is poor, is easily caused whole lamp
Pipe burns, influence high-pressure sodium lamp use and use projector that the high-pressure sodium lamp is made there is provided one kind the problem of use
The heat abstractor of high pressure mercury lamp of projector.
The technical solution adopted for the present invention to solve the technical problems is：A kind of heat abstractor of high pressure mercury lamp of projector,
Including fluorescent tube, there is the fluorescent tube fixation on first end, wick and the second end, second end to be covered with the first wind scooper, institute
It is the open circles stage body that small end is closed to state the first wind scooper, and the big end opening of first wind scooper is relative with the wick to be set
Put, be evenly distributed on first wind scooper along its center axis and fix cover on some air inlets, first wind scooper and set
There is the second wind scooper, second wind scooper is open circles stage body, the inner surface of the second wind scooper small end and described first
The outer surface sealing at the big end of wind scooper is set, and big end opening and the wick of second wind scooper be disposed opposite to each other, it is described enter
Air port is respectively positioned in second wind scooper, and the 3rd wind scooper, some described three are installed with second wind scooper
Central axis circumference uniform distribution of the wind scooper along the second wind scooper, some air inlets are located at some 3rd wind scoopers respectively
Interior, the cross section of the 3rd wind scooper is fan-shaped ring, and the big end angle of the 3rd wind scooper is more than the 3rd wind-guiding
The small end angle of cover, the big end of the 3rd wind scooper is disposed opposite to each other with the wick, is fixedly mounted on second wind scooper
There is air-supply arrangement, the big end opening of the air outlet of the air-supply arrangement and second wind scooper is oppositely arranged.
3rd wind scooper is fixedly mounted in the second wind scooper in order to more firm, the 3rd wind scooper has arc surface
And two sides, the arc surface fitted with the inner surface of second wind scooper, and opening is provided with two sides, described
Fitted with the outer surface of second wind scooper bottom surface of opening.
In order that the big end of the 3rd wind scooper is collected into more wind, the big end bottom of two neighboring 3rd wind scooper
Two adjacent sides it is bonded to each other.
In order to simplify the integral installation structure of the present invention, the air-supply arrangement is axial flow blower.
After axial flow blower is opened, the big end opening of the air outlet of axial flow blower and the second wind scooper is oppositely arranged, simultaneously
Also the big end opening with the 3rd wind scooper is oppositely arranged, and the air-flow flowed out from axial flow blower air outlet enters in the 3rd wind scooper,
Because the big end angle of the 3rd wind scooper is more than its small end angle, air inlet is located in the small end of the 3rd wind scooper, can make gas
Flow from the 3rd wind scooper air inlet outflow when, flow velocity and air pressure increase, air outlet is just to the second end on fluorescent tube, Jin Erzeng
Add the radiating efficiency at the heat-transfer rate at the second end, the second end higher；Air-flow enters the first wind scooper from air inlet, due to
The small end of first wind scooper is closing, and air-flow has been only capable of from the big end opening of the first wind scooper outflow, the first wind scooper it is big
End opening is oppositely arranged with the wick on fluorescent tube, is directly blowed to wick from the air-flow of the big end opening outflow of the first wind scooper, is made lamp
Air flow at core is accelerated, and adds the heat-transfer rate at wick, while also accelerating the air flow at first end, also increases
The heat-transfer rate at first end is added.
The beneficial effects of the invention are as follows:The heat abstractor of the high pressure mercury lamp of projector of the present invention, the air outlet of axial flow blower
It is oppositely arranged with the big end opening of the 3rd wind scooper, the air-flow flowed out from axial flow blower air outlet enters in the 3rd wind scooper, by
It is more than its small end angle in the big end angle of the 3rd wind scooper, air inlet is located in the small end of the 3rd wind scooper, and air-flow is from the 3rd
When air inlet in wind scooper flows out, flow velocity and air pressure increase, air outlet is just to the second end on fluorescent tube, and then add second
Radiating efficiency at heat-transfer rate at end, the second end is higher；Air-flow enters the first wind scooper from air inlet, due to the first wind-guiding
The small end of cover is closing, and air-flow is only capable of the big end opening outflow from the first wind scooper, the big end opening and lamp of the first wind scooper
Wick on pipe is oppositely arranged, and is directly blowed to wick from the air-flow of the big end opening outflow of the first wind scooper, is made the air at wick
Flow faster, adds the heat-transfer rate at wick, while also accelerating the air flow at first end, adds at first end
Heat-transfer rate.While second end of the present invention on to fluorescent tube carries out specific aim radiating, wick and first end are also carried out
Radiating, makes the radiating of whole fluorescent tube more uniform, good heat dissipation effect, the service life of high-pressure sodium lamp is longer, uses the high-pressure mercury
The service life for the projector that lamp is made is longer.
