Utility model content
Namely the utility model is the shortcoming for the radiating effect difference existing for current outdoor LED display screen, designs and produces a kind of outdoor electronic government affairs touch-screen with the ventilation structure of great heat radiation effect.
The technical scheme adopted is:
A kind of outdoor electronic government affairs touch-screen of ventilation structure, comprise face shield and the drain pan being arranged on face shield rear end, face shield and drain pan form a cavity, PCB is provided with in this cavity, in this PCB, front is provided with multiple LED lamp bead, the back side is provided with driving power, and this PCB is connected with multiple ventilation duct, each ventilation duct is equipped with multiple first through hole; The plurality of ventilation duct communicates with each other, and is connected with drain pan with face shield, and it comprises left and right ventilation duct, lower airway pipe and cross ventilation pipe, forms three-dimensional radiator structure.
Preferably, the plurality of ventilation duct forms a spherical public domain, and left and right ventilation duct, lower airway pipe are all communicated with this public domain with cross ventilation pipe.
Preferably, described face shield is communicated with ventilation duct by being provided with multiple second through hole, described drain pan is communicated with ventilation duct by being provided with multiple third through-hole.
Preferably, described left and right ventilation duct is 2, and lower airway pipe is 1, and cross ventilation pipe is 1.
Preferably, described left and right ventilation duct is 1, and lower airway pipe is 1, and cross ventilation pipe is 1.
The beneficial effects of the utility model are:
By being connected with multiple ventilation duct on heat sink, each ventilation duct is equipped with multiple first through hole; The plurality of ventilation duct communicates with each other, and be connected with drain pan with face shield, it comprises left and right ventilation duct, lower airway pipe and cross ventilation pipe, form three-dimensional radiator structure, thus the heat-dissipating space of display screen inside is interconnected, add strong convection, make on the one hand the heat that distributes can simultaneously from left and right, up and down, front and back shed space, on the other hand, cold air also can from left and right, up and down, front and back flow into space, therefore good heat dissipation effect.
