Abstract
The invention discloses a projector heat radiation air guide device, especially a projector bulb heat radiation air guide device. And the invention provides an air guide device able to radiate bulb heat and other parts, comprising: air guide pipe lamp seat and fan, where an angular connection pipe is installed between air inlet of the air guide pipe and air outlet of the fan, and the angular connection pipe's wall is at least made with a side hole. On the condition of not increasing the number of fans, it uses the original heat radiation air guide device to be able to effectively make air feed and heat radiation on other parts such as color wheel, assuring temperature of each key point in the projector accords with the technical requirements. Besides, by setting steps on the air guide pipe, it can achieve the purposes of regulating and controlling air speed, air direction, and air quantity.
Description
Technical field
The present invention relates to radiating treatment, the air ducting of projector, particularly be suitable for projector bulb heat radiation and handle air ducting
Background technology
The reliability of projector depends primarily on the control of internal temperature, and the bulb that projector uses then is wherein topmost thermal source, also is simultaneously the device a little less than reliability is highly brittle.There is harsh use restriction in the manufacturer of bulb to the service condition of bulb, if improper use, then can bringing gently then, bulb life descends, heavy then the serious consequence of quick-fried lamp, so in the entire machine design and later stage production control of projector, aspect reliability, whether the use of everybody more concern bulb meets the requirements.
In projector, also have some devices also relatively more responsive to temperature, such as color wheel motor in the DLP projector, its working temperature must be controlled at below 80 ℃, but because colour wheel is in the bulb front end, the heat that bulb gives off is very big to the color wheel motor influence, also must be by guiding certain distinguished and admirable heat radiation.But increase fan cost and noise are all had certain influence.
Present general way is that guiding is distinguished and admirable blows to bulb inside, but effect always is not fine, and particularly along with the power of present bulb is increasing, temperature control is difficult to take into account.As application number is in No. 200410039674.9 application for a patent for invention open files, provide a kind of and near the fan of projector, guide vane has been installed, guide the distinguished and admirable bulb inside that blows to, the structure of being dispelled the heat in the wick position, guide vane can only be divided into two parts by front and back with wind in this structure, to the rear section blow to the wick place, blow to the lead-in wire place to forward part, just solve the heat dissipation problem at wick place, and can not solve the problem of color wheel motor being carried out efficiently radiates heat, cooling.
Summary of the invention
Technical matters to be solved by this invention provides a kind of can the heat radiation to wick, again the air ducting that can dispel the heat to other positions simultaneously.
The technical solution adopted in the present invention is: projector heat radiation-treatment wind-guiding device, comprise lamp socket, the fan of being with guide duct, between the air inlet of guide duct and fan outlet, the angle connecting pipe is installed, has an other hole on the tube wall of described angle connecting pipe at least; The colour wheel of opening in projector in described other hole.
The air inlet of angle connecting pipe and the axis of air outlet are 90 °～160 ° angle.
Inflow point at guide duct is provided with to the inboard step that extends of lamp socket.
Further improve as of the present invention, the both sides up and down of described step respectively and gapped between the guide duct sidewall form uptake and following air port again, and the top of above-mentioned step and the air inlet of guide duct form preceding air port.
Adopt projector heat radiation-treatment wind-guiding device of the present invention, under the situation that does not increase number of fans, utilize original heat radiation air ducting, just can be effectively to the heat radiation of blowing of other positions such as colour wheel, guaranteed that the temperature of inner each key point of projector reaches technical requirement.And, can reach the purpose of adjustment and controlled wind speed, wind direction, air quantity on guide duct by step is set.This device can shorten the cycle of projecting camera light bulb thermal design greatly, can be applied to follow-up production easily, can make things convenient for, shorten the Change In Design cycle that brings because of the bulb change.

Embodiment
The present invention is described in detail below in conjunction with accompanying drawing.
Projector heat radiation-treatment wind-guiding device, comprise lamp socket 1, the fan 2 of being with guide duct 5, between the air inlet of guide duct 5 and fan 2 air outlets, angle connecting pipe 3 is installed, at least have an other hole 4 on the tube wall of angle connecting pipe 3, the part of the wind of fan 2 generations is dispelled the heat at other positions of need dispelling the heat, as the colour wheel of opening in projector with other hole 4 to projector inside.A plurality of other holes can be set certainly as required.For installation site according to the structural adjustment fan of projector inside, the air inlet 31 of angle connecting pipe 3 and the axis of air outlet 32 are set to be 90 °～160 ° angle, solved in the prior art fan directly has been connected the problem that causes the fan installation site to be restricted with lamp socket.
Be provided with to the lamp socket 1 inboard step 6 that extends in the inflow point of guide duct 5, can adjust and control air intake effectively.
Embodiment:
As shown in Figure 1, in the outlet of fan 2, be connected with angle connecting pipe 3, on the tube wall of this angle connecting pipe 3, have an other hole 4, the colour wheel installation site of the corresponding projector of the direction in other hole 4 inside, the position of colour wheel does not mark in the accompanying drawings.Because other hole can make the air quantity that flows to guide duct reduce, when determining the perforate size, to determine the temperature of the air quantity and the bulb at guide duct place simultaneously.
The distinguished and admirable change direction that can blow out fan by the angle connecting pipe, and guide guide duct into, this angle connecting pipe 3 as shown in Figure 2, air inlet 31 becomes 90 ° of layouts with axis between the air outlet 32, so just fan can be adjusted to the position that helps installing, make inside compact more, conserve space.The band angle connecting pipe 3 of She Zhiing can be convenient to adjust and determine the position of opening in other hole 4 according to the structure of projector inside simultaneously.The air inlet of the guide duct 5 on the air outlet 32 of angle connecting pipe 3 and the lamp socket 1 is connected.
Air inlet at guide duct 5 is provided with step 6, adjusts structure as air intake.In order to reach the effect of transferring wind more efficiently, step 6 is set to stairstepping, the both sides up and down of step 6 respectively and gapped between guide duct 5 sidewalls form uptake 8 and following air port 7, and the ladder top of step 6 and the air inlet of guide duct 5 form preceding air port 9.Preceding air port 9 adopts the top of step 6 to form for extending to lamp socket 1 inner chamfer.In the design adjusting stage, this step 6 can use resistant to elevated temperatures PBS plastic production, is bonded on the lamp socket, and plastics can conveniently cut adjusts size, shape, thereby by adjusting the gap in uptake 8, following air port 7 and preceding air port 9, control is to the air quantity and the wind direction of wick position.After test is passed through, can make, be fixed on then on the lamp socket, can certainly process with the die sinking of lamp socket one of alloy.
