Description
Technical field
The utility model relates to LED Display Technique field, especially outdoor LED display module.
Background technology
LED display screen has the advantages such as high brightness, low-power consumption, life-span length, high-weatherability, is widely used in outdoor demonstration.Particularly large-scale display screen, the display module that is arranged with LED luminescence unit by polylith dot matrix forms, and has realized modularization and has installed.Existing LED display module, owing to will solving heat dissipation problem, so conventionally at the heat generating spot place of pcb board coating heat-conducting resin, be then connected with cover plate by heat-conducting resin, then just plays the effect of heat radiation.Present cover plate is all the aluminium horizontal panel of a monoblock, and intensity is low, easily distortion, and also the radiating effect of heat-conducting resin is undesirable, and meanwhile, drain pan is not fine with the sealing of cover plate, occurs the phenomenon of infiltration.
Utility model content
The technical problems to be solved in the utility model is: the Novel outdoor LED module that the convenient heat radiation that a kind of rapid heat dissipation, intensity are high is provided.
In addition, the utility model also requires to improve the sealing of outdoor LED module.
The solution that the utility model solves its technical problem is:
A kind of Novel outdoor LED module of convenient heat radiation, include from inside to outside heat-dissipating cover plate, heat radiation drain pan, pcb board and cover on the face shield outside pcb board, on described pcb board, there is heat generating spot, described heat-dissipating cover plate is provided with the heat conduction convex surface of at least one outwardly convex, and described heat conduction convex surface is against on the heat generating spot of pcb board and is connected with its heat conduction.Described heat conduction connects, and can be direct contact, or add the heat-conducting resin of thin layer.
Further preferred, that described heat radiation drain pan has is corresponding with the heat conduction convex surface of heat-dissipating cover plate, pass and hold its netted hollow hole for it.
Further preferred, described heat generating spot has multiple, and the quantity of heat conduction convex surface and netted hollow hole is all corresponding with heat generating spot.
Further preferred, in described multiple heat conduction convex surfaces, having a heat conduction convex surface at least is to connect with corresponding heat generating spot heat conduction by heat-conducting resin.
Further preferred, described heat radiation drain pan have a circle for hide fluid sealant, round the undercut of heat radiation drain pan periphery.
Further preferred, described heat-dissipating cover plate is the Al-alloy casing of integrated punching moulding.
Further, it must be all that heat conduction convex surface directly contacts with heat generating spot that the invention does not limit described heat conduction connection that must be all, that is to say, allow in described multiple heat conduction convex surfaces, having a heat conduction convex surface at least is to connect with corresponding heat generating spot heat conduction by heat-conducting resin.
The beneficial effects of the utility model are: the utility model is directly connected contact with thermal conductivity points heat conduction by cover plate convex surface, accelerate distributing of heat.
Punching press simultaneously has the Aluminum cover of convex surface, and intensity is also higher, is difficult for flexural deformation.Further, due to the convex surface of cover plate and the hollow hole of drain pan corresponding, make both assemblings tightr, water resistance is better.
The utility model can be widely used in outdoor LED display screen field.
Accompanying drawing explanation
Fig. 1 is the cover plate front view of a kind of embodiment of the present utility model;
Fig. 2 is the side partial sectional view of a kind of embodiment of the present utility model.
The specific embodiment
As shown in Figure 1 and Figure 2, a kind of Novel outdoor LED module of convenient heat radiation, includes from inside to outside heat-dissipating cover plate 1, heat radiation drain pan 2, pcb board 3 and covers on the face shield 4 outside pcb board.By conventional wires design, the drive IC (heat generating spot 31) of the pcb board 3 with dot matrix arrangement is concentrated on to subregion, these regions are all multiple, discontinuous, skewness conventionally.Corresponding described heat generating spot 31, on heat-dissipating cover plate 1, arranges the heat conduction convex surface 11 of outwardly convex, and heat conduction convex surface is directly against on heat generating spot 31, is connected with its heat conduction.Because heat-dissipating cover plate 1 contacts better with heat generating spot 31, accelerate the heat radiation of LED display module.
Preferably, described heat radiation drain pan 2, have corresponding with the heat conduction convex surface 11 of heat-dissipating cover plate 1, pass and hold its netted hollow hole for it; Then be provided with a circle for hiding the undercut of fluid sealant round heat radiation drain pan 2 peripheries.By the linking of heat radiation drain pan 2, heat-dissipating cover plate 1 is installed more firm, sealing effectiveness is better simultaneously.
Preferably, described heat generating spot 31 has multiple, and the quantity of heat conduction convex surface 11 and netted hollow hole is all corresponding with heat generating spot 31.By with heat generating spot 31 heat conduction convex surface 11 one to one, make overall better heat-radiation effect.
Preferably, in multiple heat conduction convex surfaces 11 of the present utility model, having a heat conduction convex surface 11 at least is to connect with corresponding heat generating spot 31 heat conduction by heat-conducting resin.Due to the fabrication error of punching press, likely having one or more heat conduction convex surface 11 can not directly be connected with heat generating spot 31 heat conduction, and need to, at both direct full-filling heat-conducting resins, reach better radiating effect this time.
Preferably, heat-dissipating cover plate 1 is the aluminium alloy plate of an integrated punching moulding.Punching press has the heat-dissipating cover plate 1 of heat conduction convex surface 11, and than existing plane heat conducting cover plate, intensity is higher, and the reliability of integral LED module is larger.
These are only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
