Abstract
The utility model provides an advertising board with an LED display screen, comprising a box body, a postpositive exhaust fan, a postpositive fan bracket and a postpositive fan cover, wherein the postpositive fan cover is arranged on the back surface of the box body; the postpositive fan bracket is welded on the postpositive fan cover; and the postpositive exhaust fan is arranged on the postpositive fan bracket. The advertising board has the benefits that the existing postpositive fan cover changes a driven exhaust mode into an active exhaust mode so as to lead the radiating effect thereof to be best; furthermore, the lateral fans are added, so that the radiating effect is enhanced and the advertising board can be ensured to work normally under high temperature, especially under the daylight environments of summer, and the advertising board has good displaying effect.
Description
Technical field
The utility model relates to a kind of billboard, especially relates to the billboard that LED shows.
Background technology
In recent years, the manufacture craft level of led chip and display technique are constantly progressive, make it show in large tracts of land, obtain promotion and application widely day by day in fields such as physical culture, advertisement, finance, theater, exhibition, airport and traffic especially, and at present just towards high brightness more, littler density, better homogeneity, more excellent color representation ability and more full functional promotion aspect development, the DEVELOPMENT PROSPECT of all kinds of display screens is very wide.
There is following defective in present most of ground LED display casing: outward appearance heaviness, water resistance are general, it is bad to dispel the heat, especially greatly usually cause screen flower (the screen Show Color is undesired) because of its thermal value daytime in summer, interior environment temperature is too high not only to influence image effect, but also has seriously shortened the life-span of product.
LED display a kind of of the prior art as shown in Figure 1, its rearmounted fan guard are double-deck water proof type window shutter, though its water resistance can satisfy round-the-clock requirement of shelter, are passive exhaust after all, and its heat sinking function is obvious not as the active heat removal effect.
The utility model content
The utility model is in order to overcome above-mentioned the deficiencies in the prior art, and the utility model provides a kind of LED display billboard of good heat dissipation effect.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of LED display billboard, it comprises casing, rearmounted extraction fan, rearmounted blower tray and rearmounted fan guard, described rearmounted fan guard is arranged on the back side of this casing, described rearmounted blower tray is welded on this postposition fan guard, and described rearmounted extraction fan is arranged on this postposition blower tray.
The scheme that the utility model solves further technical matters is: pass through screw retention between described rearmounted extraction fan and this postposition blower tray.
The scheme that the utility model solves further technical matters is: described rearmounted fan guard is welded on this casing and sealing setting fully.
The scheme that the utility model solves further technical matters is: it further comprises side fan guard and side fan, and described side fan guard is arranged on the side of described casing, and described side fan is arranged on this side fan guard.
The scheme that the utility model solves further technical matters is: described side fan guard and side fan are symmetricly set on the side of this casing.
Compared to prior art, LED display billboard of the present utility model is for being improved to initiatively exhaust with former rearmounted fan guard by passive exhaust, make its radiating effect perform to the best, and increased the side fan, more strengthened the effect of heat radiation, guaranteed it at high temperature, especially still can operate as normal in the environment on daytime in summer, display effect is good.
Description of drawings
Fig. 1 is the structural representation of LED display billboard of the prior art.
Fig. 2 is the structural representation of LED display billboard of the present utility model.
Fig. 3 is the part-structure decomposing schematic representation of LED display billboard of the present utility model.
Embodiment
Following content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
Because the LED screen needs all weather operations, its thermal value is very big, and ventilation and heat is required height, especially greatly usually causes screen flower (the screen Show Color is undesired) because of its thermal value daytime in summer.
See also Fig. 2 to Fig. 3, the utility model provides a kind of LED display billboard, and it comprises casing 10, side fan guard 11, side fan 12, rearmounted extraction fan 13, rearmounted blower tray 14 and rearmounted fan guard 15.
Described side fan guard 11 is arranged on the side of described casing 10, and described side fan 12 is arranged on this side fan guard 11.Described side fan guard 11 and side fan 12 are symmetricly set on the side of this casing 10.
Described rearmounted fan guard 15 is arranged on the back side of this casing 10, and described rearmounted blower tray 14 is welded on this postposition fan guard 15, and described rearmounted extraction fan 13 is arranged on this postposition blower tray 14.
Pass through screw retention between described rearmounted extraction fan 13 and this postposition blower tray 14.
Described rearmounted fan guard 15 is welded on this casing 10 and sealing setting fully.
Compared with prior art, the beneficial effects of the utility model are, former rearmounted fan guard is improved to initiative exhaust by passive exhaust, make its radiating effect perform to the best, and increased the side fan, and more strengthened the effect of heat radiation, guaranteed that it is at high temperature, especially still can work in the environment on daytime in summer, display effect is good.
