In figure: the first heat sink 1, thermally conductive adhesive layer 2, thermal conductive silicon rubber mat 3, the second heat sink 4, fan guard 5, rectangle Frame 6, aluminium radiator fin 7, fan drum 8, fan 9, the first threaded hole 10, ventilation cell lyriform pore 11, the second threaded hole 12, combined type Radiator 13, baffle 14, support rod 15, third threaded hole 16, heat release hole 17.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.

Referring to Fig.1-2, a kind of radiator of LED display, including the first heat sink 1, rectangular frame 6 and fan drum 8, the front of fan drum 8 symmetrically equidistantly offers multiple heat release holes 17, the heat dissipation effect of enhancement device.

Baffle 14 is fixedly installed at the dorsal edge of first heat sink 1, the surface of baffle 14 is applied coated with heat loss through radiation Material, heat loss through radiation coating includes nano carbon-base material, so that baffle 14 reaches better heat dissipation effect.

And first heat sink 1 the back side in the middle part of be uniformly fixedly installed with multiple support rods 15, the front of the first heat sink 1 is viscous Thermally conductive adhesive layer 2 is posted, the front of thermally conductive adhesive layer 2 is pasted with the second heat sink 4, the front center position of the second heat sink 4 It is fixedly installed with combined radiator 13, and the positive two sides of the second heat sink 4 are fixedly installed with thermal conductive silicon rubber mat 3, combined Formula radiator 13 includes multiple dismountable superposition radiating fins, forms convection channel between adjacent radiating fin, facilitates sky Gas realizes convection current between radiating fin, accelerates distributing for heat.

The positive four corners of second heat sink 4 offer the second threaded hole 12, and the positive four corners of rectangular frame 6 are opened Equipped with first threaded hole 10 corresponding with the second threaded hole 12, and the inside of rectangular frame 6 is equidistantly fixedly installed with multi-disc aluminium The front of cooling fin 7, fan drum 8 symmetrically offers third threaded hole 16 corresponding with the first threaded hole 10, third screw thread The inside in hole 16, the first threaded hole 10 and the second threaded hole 12 is threaded with fixing bolt, the back side etc. of fan drum 8 jointly Away from offering a plurality of ventilation cell lyriform pore 11, and the internal symmetry of fan drum 8 is equipped with fan 9, and the outside of each fan 9 is all provided with There is fan guard 5, fan guard 5 is fixedly installed in the front of fan drum 8, for protecting fan 9 from external environment Damage.
