Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
Embodiment one
As shown in Figures 1 and 2, the utility model embodiment one provides a kind of LED display, the LED display module 100 packet
Mould group main body 110 and radiating frame 120 are included, radiating frame 120 is set to the back side of mould group main body 110, in mould group main body 110
Back side form multiple longitudinally disposed heat-insulated air ducts 11, each heat-insulated air duct 11 is provided with bottom side air inlet 12 and top side outlet air
Mouth 13 is separated by between adjacent heat-insulated air duct 11 by partition 14 two-by-two.
In the present embodiment, as shown in Figure 1, in order to enable the heat that mould group main body 110 generates when working can quickly dissipate
Heat into heat-insulated air duct 11, meanwhile, also in order to which heat-insulated air duct 11 generates distinguished and admirable mould group main body 110 back side of can preferably taking away
Heat, using following structure setting, the side side wall in heat-insulated air duct 11 is the back side of mould group main body 110, so that mould group main body 110
Back side be connected directly with heat-insulated air duct 11 it is logical.Meanwhile also several heat release holes can be set in the back side of mould group main body 110, with into
One step enhances its heat dissipation effect.
As shown in Figure 1, integral structure both can be used between mould group main body 110 and radiating frame 120, it can also pass through fastening
Part carries out connected.When being connected between mould group main body 110 and radiating frame 120 by fastener, which is screw
Component or snap component.The section configuration in heat-insulated air duct 11 in non-uniform thickness be distributed, may make mould group main body 110 inner heat and
External environment including solarization inputs heat, high-efficiency heating enclosure interior air, to strengthen air vertical natural convection current
(stack effect) radiates.
As shown in Figure 1, the cross section in the heat-insulated air duct 11 in the present embodiment is quadrangular ring-shaped structure, in addition to this, also
Can be set as circular according to actual needs, be perhaps set as oval ring-type or be set as other than quadrangle other are more
Side shape is cyclic annular.Since metal plate has better heating conduction, the radiating frame 120 in the present embodiment preferably uses metal knot

So, multiple 100 vertical stacks of LED display module, the length in heat-insulated air duct 11 are superimposed therewith, advantageous by this
It influences, stack effect and heat dissipation effect are significantly reinforced therewith.
Embodiment three
The utility model embodiment three provides a kind of LED display, which includes heat-dissipating frame and several LED
Display module, several LED display modules are arranged in arrays, and heat-dissipating frame is installed in the back side of several LED display modules, if with
The back side of dry LED display module forms heat-dissipating frame and is equipped with the heat-insulated air duct in multiple longitudinal directions, each heat-insulated air duct be provided with bottom side into
Air port and top side air outlet are separated by between adjacent heat-insulated air duct by partition two-by-two.
Compared with the LED display of embodiment two, the LED display of the present embodiment, heat-dissipating frame is monolithic construction,
Set on the back side of several LED display modules, and not as documents 2, in the mould group master of every LED display module 100
The back side of body 110 is respectively provided with a radiating frame.In addition to this, the structure with embodiment two of the heat-dissipating frame of the present embodiment is basic
Unanimously, i.e., be similarly in addition to this also can be according to practical need for quadrangular ring-shaped structure for the cross section in its heat-insulated air duct formed
It wants, is set as circular, is perhaps set as oval ring-type or is set as other polygonal ring shapes other than quadrangle.By
There is better heating conduction in metal plate, the radiating frame in the present embodiment preferably uses metal structure, i.e. the present embodiment
In radiating frame by several metal plates it is built-up.
In addition, the back side that the various embodiments described above occur, refer specifically to relative to display plane it is another then, i.e. display plane institute
It is positive side in side, is back side backwards to display plane side.
LED display module and LED display in the utility model embodiment, radiating frame are fixedly arranged on its mould group main body
Back side, multiple longitudinally disposed heat-insulated air ducts are formed with the back side in its mould group main body.So, heat-insulated wind can be utilized
