Abstract
The utility model discloses a heat radiator for LED display screen, the LED display screen is installed on the frame, the LED display screen includes PCB circuit board and installs the LED lamp pearl on PCB circuit board, heat abstractor is including installing the heat conduction silica gel sheet of PCB circuit backboard face, heat conduction silica gel sheet with the size of PCB circuit backboard face is suitable install a heat -conducting plate outside the heat conduction silica gel sheet be provided with a plurality of heat conduction fins on the heat -conducting plate. This heat abstractor simple structure adopts heat conduction silica gel sheet, heat -conducting plate and heat conduction fin to dispel the heat to PCB circuit board, and the radiating effect is good, has guaranteed the normal use of LED display screen.
Description
Technical field
LED display of the present invention, particularly relates to a kind of heat abstractor of LED display.
Background technology
LED display is widely used.But LED display inner heat generating components is more, major heat producing components is LED, drive IC and Switching Power Supply etc., therefore needs to carry out heat dissipation design to LED large-screen.But, existing radiating mode not only complex structure, and cost is higher.
Summary of the invention
For solving above-mentioned problems of the prior art, the purpose of this utility model is to provide the heat abstractor of simple, the lower-cost LED display of a kind of structure.
For this reason, technology of the present utility model solves as follows:
A kind of heat abstractor of LED display, described LED display is arranged on housing, described LED display comprises PCB and is arranged on the LED lamp bead in PCB, described heat abstractor comprises the heat-conducting silica gel sheet being arranged on the described PCB back side, the sizableness at described heat-conducting silica gel sheet and the described PCB back side, one heat-conducting plate is installed outside described heat-conducting silica gel sheet, described heat-conducting plate is provided with multiple heat transmission fin.
Preferably, described heat transmission fin is longitudinally arranged on described heat-conducting plate, is beneficial to the quick transmission of heat.
The beneficial effects of the utility model are as follows:
Adopt heat-conducting silica gel sheet, heat-conducting plate and heat transmission fin to dispel the heat to PCB, good heat dissipation effect, ensure that the normal use of LED display; Its structure is simple, easy to use.
Accompanying drawing explanation
Fig. 1 is provided with the structural representation of the LED display of the utility model heat abstractor.
Embodiment
Be described in detail below in conjunction with the structure of accompanying drawing to LED display heat abstractor of the present utility model.
Figure 1 shows that the LED display being provided with the utility model heat abstractor.LED display is arranged on metal framework usually, the LED lamp bead 11 that LED display comprises PCB 10 and is arranged in PCB 10, and described heat abstractor is arranged on the back side comprising and be arranged on PCB.
As shown in the figure, this heat abstractor comprises the heat-conducting silica gel sheet 12 being arranged on described PCB 10 back side, the sizableness at described heat-conducting silica gel sheet 12 and the described PCB back side, one heat-conducting plate 14 is installed outside described heat-conducting silica gel sheet 12, described heat-conducting plate 14 is provided with multiple heat transmission fin 13.
Preferably, described heat transmission fin 13 is arranged with multirow in parallel at described heat-conducting plate 14 back side, forms gap between adjacent rows heat transmission fin.Each heat transmission fin is all longitudinally arranged, so that heat can upwards scatter and disappear fast.
