Utility model content
To be solved in the utility model is that outdoor LED display screen is because area is compared with the heat dissipation problem and the windage problem that cause greatly.
For solving the problems of the technologies described above, the utility model provides a kind of outdoor LED display screen that can wind-dispelling heat-dissipating, it includes a plurality of LED modules, described LED module includes shell and is loaded on the circuit board in shell, on LED module, have ventilation slot, the heat radiator that circuit board heat can be led is away posted at the shell back side, and heat radiator is the hardware that is easy to heat conduction, which is provided with dispelling wind hole.
As technique scheme preferably, between described heat radiator and shell, leave gap, stagger in described dispelling wind hole and ventilation slot position.
As technique scheme preferably, the described shell back side is provided with a plurality of cooling vents, staggering in the position in cooling vent and dispelling wind hole, is provided with the heat-conducting resin contacting with circuit board in cooling vent, heat radiator is close to heat-conducting resin.
As technique scheme preferably, described cooling vent is arranged with O-ring seal outward.
As technique scheme preferably, described heat radiator is aluminium matter member.
The disclosed a kind of outdoor LED display screen that can wind-dispelling heat-dissipating of the utility model, include a plurality of LED modules, described LED module is provided with heat radiator, can effectively solve the heat dissipation problem of LED display, and be provided with ventilation slot air is easy to by LED display, reduce windage.The utility model is simple in structure, easily makes, and can be applicable to produce LED light fixture.
