Block, the side of the block that catchments are equipped with water hole, and the first side of the water hole is connect with external water storage device pipeline.It is described
It is equipped with and the one-to-one bypass channel of cold rinse bank in the opening of the other side of water hole.
In the preferred embodiment of the utility model, the first side opening bore of the water hole is less than its second side opening
Bore.
In the preferred embodiment of the utility model, heat dissipation metal is equipped between each LED lamp bead and the substrate
Piece.
In the preferred embodiment of the utility model, the heat sink is made of copper material.
In the preferred embodiment of the utility model, the cross-sectional layers of the cold rinse bank are semicircle.
Corresponding cold rinse bank is arranged by using water-cooling, and for each column LED lamp bead in the technical solution of the utility model,
Each column LED lamp bead is individually radiated, to guarantee effectively to radiate to each column lamp bead, to improve whole to LED display
The heat dissipation effect of body, and then reduce the probability of LED lamp bead aging.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, the structure that can also be shown according to these attached drawings obtains other attached drawings.
Fig. 1 is the structural schematic diagram for one embodiment of energy-saving LED display screen that the utility model has high heat dispersion；
Fig. 2 is the cross-sectional view of heat sink；
Fig. 3 is the cross-sectional view in Fig. 2 at A-A；
The utility model aim is realized, the embodiments will be further described with reference to the accompanying drawings for functional characteristics and advantage.
Specific embodiment
The utility model proposes a kind of energy-saving LED display screens with high heat dispersion.
Referring to Fig.1-2, Fig. 1 is the knot for one embodiment of energy-saving LED display screen that the utility model has high heat dispersion
Structure schematic diagram, Fig. 2 are the cross-sectional view of heat sink.
As shown in Figs. 1-2, in the utility model embodiment, this has the energy-saving LED display screen packet of high heat dispersion
Include substrate 100 and heat sink 200.The front of substrate 100 is equipped with several regularly arranged LED lamp beads 110.Heat sink 200
The back side of substrate 100 is set, which is provided with cold rinse bank 210 corresponding with each column LED lamp bead 110, the front and back two of heat sink 200
Side is respectively equipped with the block 300 that catchments, and the side for the block 300 that catchments is equipped with water hole 310, the first side of water hole 310 and external storage
The connection of water installations pipeline.It is equipped with and the one-to-one bypass channel 311 of cold rinse bank 210 in the opening of the other side of water hole 310.
When needing cooling, it is passed through cold water from the block 300 that catchments of 200 first side of heat sink, cold water is flowed through from cold rinse bank 210
When, the heat of each column LED lamp bead 110 is taken away respectively, then is flowed out from catchmenting 300 pieces for 200 second side of heat sink, be back to from
External water storage device is expelled directly out.
Corresponding cold water is arranged by using water-cooling, and for each column LED lamp bead 110 in the technical solution of the utility model
Slot 210 is individually radiated each column LED lamp bead 110, to guarantee effectively to radiate to each column lamp bead 110, thus raising pair
The heat dissipation effect of LED display entirety, and then reduce the probability of LED lamp bead aging.Meanwhile it is simple by using the block 300 that catchments
