Description
Technical field
The present invention relates to heat abstractor, particularly a kind of large-size LCD back forced air cooling device.
Background technology
LCD usable range in electron trade is more and more wider at present, and size is also increasing, and corresponding power consumption also becomes more and more higher, and the heat of generation is also just more and more.If heat can not distribute from LCD timely and effectively, will cause the LCD temperature too high, even surpass the temperature specification of liquid crystal material, thereby influence the LCD reliability.Particularly in interactive multimedia teaching and conference system; in order to protect tangible LCD surface not scratched by hard thing; usually arrange a clear glass (or resin) in LCD the place ahead, in order to guarantee display effect, glass (or resin) can be as far as possible little with the gap on LCD surface simultaneously.In this case, LCD surface heat just is difficult to distribute.Heat dissipating method commonly used at present is to dispel the heat at the LCD back.
Back radiating mode (air-cooled) commonly used at present has three kinds: first kind is natural heat dissipation, and shortcoming is to be not suitable for the big LCD of power consumption; Second kind the fan exhausting is installed above the LCD back, shortcoming is that fan is in high-temperature region work, and serviceable life is short; The third directly installs fan to up-draught below the LCD back, shortcoming is a uneven air, can only local dispel the heat, if LCD is oversize, needs a plurality of fans are installed, thereby causes cost to rise, and total noise of centrifuge is excessive.
Summary of the invention
The objective of the invention is to overcome the shortcoming and defect of above-mentioned prior art, a kind of large-size LCD back forced air cooling device be provided, the present invention has that noise is little, air quantity is big, heat radiation evenly and area of dissipation big.
Purpose of the present invention realizes by following proposal: a kind of large-size LCD back forced air cooling device, comprise fan, also be provided with kuppe at fan outlet, described kuppe, comprise the air delivery duct, distribute the air channel, described air delivery duct, distribute and be provided with splitter between the air channel, the described upper side wall that distributes the air channel offers a plurality of air outlet openings successively, the described wedge shape that is shaped as that distributes the air channel, described air delivery duct and the junction that distributes between the air channel are arc chord angle.
The aperture area of described air outlet opening, middle part to the two ends that distribute the air channel that distribute the air channel certainly become big successively gradually.
Described splitter is made of two circular arc vanes, and its global sections shape is " people " font.
Described fan is a kind of in tubeaxial fan or the eddy current fan.
Large-size LCD back forced air cooling device of the present invention is installed in the below at LCD back, its kuppe has adopted the air delivery duct and has distributed the air channel, kuppe can all be concentrated the air output of fan within it, and air-flow carried out current stabilization, stable air-flow is divided into the air-flow that two plume amounts equate substantially by splitter, flows to the two ends that distribute the air channel by the middle part that distributes the air channel respectively, is upwards discharged equably by air outlet opening at last, the LCD back is cooled off, thereby reach the purpose of heat radiation.
The present invention is with respect to prior art, have following advantage and effect: since air-flow enter distribute the air channel after, can produce along the phenomenon of journey pressure drop and flow velocity reduction, therefore, the air channel section shape that distributes of the present invention has adopted wedge structure, make air-flow through distribute the air channel and get rid of by air outlet opening after still have certain pressure and speed, guaranteed the abundant heat radiation at LCD back; The cross section is that the splitter of circular arc has further reduced the pressure drop of air-flow in kuppe; Because the aperture area of air outlet opening is, middle part to the two ends that distribute the air channel that distribute the air channel certainly become big successively gradually, have guaranteed to distribute the flow unanimity of the air outlet opening air-flow of top, air channel, are dispelled the heat uniformly in the LCD back; Adopt the air cooling equipment of the present invention, under the blast and air quantity prerequisite that guarantee each air outlet opening, the area of dissipation (or weighing up the wind area) of fan can be expanded to the area of dissipation of several times limitedly as large-size LCD back; Noise of the present invention is little, and long service life is simple and compact for structure, and is with low cost, easy to utilize.
Description of drawings
Fig. 1 is the plan structure synoptic diagram of large-size LCD back forced air cooling device of the present invention.
Fig. 2 is the structural representation of facing of large-size LCD back forced air cooling device of the present invention.
Embodiment
Below in conjunction with embodiment and accompanying drawing the present invention is described in further detail, but embodiments of the present invention are not limited thereto.
Embodiment
As shown in Figure 1, large-size LCD back forced air cooling device of the present invention, comprise fan 1, be provided with kuppe at fan 1 air outlet, described kuppe comprises air delivery duct 2, distributes air channel 5, described air delivery duct 2, distribute and be provided with splitter 3 between the air channel 5, the described upper side wall that distributes air channel 5 offers a plurality of air outlet openings 4 successively.
This kuppe can all be concentrated the air-out of fan 1 within it, simultaneously air-flow 6 is carried out the current stabilization effect; Air-flow 6 will be divided into the air-flow 6 that two plume amounts equate substantially through after the splitter 3, respectively to the two ends air-supply that distributes air channel 5.
Because air-flow 6 is to arrive two ends from the middle part that distributes air channel 5, at this moment, the flow of air-flow 6 can reduce gradually, in order to guarantee to distribute the air outlet opening 4 flow unanimities of 5 tops, air channel, the aperture area of this air outlet opening 4, middle part to the two ends that distribute air channel 5 that distribute air channel 5 certainly become big successively gradually.
In order to reduce the pressure drop of air-flow 6, described splitter 3 is made of two circular arc vanes, and its global sections shape is " people " font.
In order further to reduce the pressure drop of air-flow 6, described air delivery duct 2 and the junction that distributes between the air channel 5 are arc chord angle.
Described fan 1 is a tubeaxial fan, but also can adopt eddy current fan.
As shown in Figure 2 and since air-flow 6 enter distribute air channel 5 after, can produce along the journey pressure drop, wind speed also can reduce, and has certain pressure and speed in order to guarantee air-flow 6, will distribute the wedge structure that is shaped as in air channel 5.
Large-size LCD back forced air cooling device of the present invention is installed in the below at LCD back, because its kuppe has comprised air delivery duct 2 and has distributed air channel 5, the air output of fan 1 all can be concentrated within it, and air-flow 6 carried out current stabilization, stable air-flow 6 is divided into the air-flow 6 that two plume amounts equate substantially by splitter 3, flow to the two ends that distribute air channel 5 by the middle part that distributes air channel 5 respectively, upwards be expelled to the back of LCD at last equably by air outlet opening 4, the LCD back is cooled off, thereby reach the purpose of heat radiation.
As mentioned above, just can realize the present invention preferably.The foregoing description only is preferred implementation of the present invention; but embodiments of the present invention are not restricted to the described embodiments; other are any not to deviate from change, the modification done under spirit of the present invention and the principle, substitute, combination, simplify; all should be the substitute mode of equivalence, be included within protection scope of the present invention.
