Problems solved by technology
[0004] Since the LED display screen works by converting electrical energy into light energy during specific work, some heat will inevitably be generated when it is working and transmitting video signals to the outside world. Working at room temperature, too high working temperature will not only shorten its service life, but also may cause the internal electrical components of the LED display to be burned. In order to avoid this situation, as far as the current LED display is concerned Some heat dissipation structures are installed, such as metal heat sinks or fans for heat dissipation. More cautiously, some manufacturers also install independent liquid circulation cooling systems for LED displays. Although the above heat dissipation methods are not suitable for LED displays The heat dissipation has some contribution, but the installation of these heat dissipation devices will not only increase the overall weight of the LED display, but more importantly, it will greatly increase the production cost of the LED display, and this is the main shortcoming of the traditional technology

Embodiment Construction
[0035] Such as Figures 1 to 7 As shown, a ventilation and heat dissipation structure of an LED display screen includes an LED module 100 and a plurality of ventilation holes 200 , and the plurality of ventilation holes 200 are arranged on the LED module 100 .
[0036] Such as Figures 1 to 2 As shown, each of the ventilation holes 200 is set through the LED module 100, and the spaces on both sides of the LED module 100 are connected through the ventilation holes 200, so that the air on one side of the LED module 100 can be The air flows to the other side of the LED module 100 through the ventilation hole 200 .
[0037] When the air flows from one side of the LED module 100 to the other side of the LED module 100 through the ventilation hole 200, the airflow generated by the air flow takes away and dissipates the heat generated in the LED module 100. to the external environment.
[0038] Such as Figures 1 to 7 As shown, the LED module 100 includes a bottom case 10 and a t...

The invention relates to a ventilating and heat-radiating structure and a heat-radiating method of an LED (light-emitting diode) display screen. The ventilating and heat-radiating structure comprises an LED module and a plurality of vent holes, wherein a plurality of the vent holes are formed on the LED module in array, and each vent hole penetrates through the LED module; the spaces on two sidesof the LED module are communicated together through the vent holes so that the air on one side of the LED module can flow to the other side of the LED module through the vent holes; and when the air flows from one side of the LED module to the other side of the LED module through the vent holes, the airflows generated by air flowing take the heat generated in the LED module away and dissipate theheat to the external environment.
Description
technical field [0001] The invention relates to a heat dissipation structure and a heat dissipation method of an LED display screen, in particular to a structure and a method for dissipating heat from an LED display screen by utilizing the air flow generated by air flow. Background technique [0002] As we all know, LED, also known as light-emitting diode, is a solid-state semiconductor device that can directly convert electricity into light energy. Because the LED illuminant has the characteristics of energy saving, long service life, and no harmful substances such as mercury inside for easy recycling, LED has been widely used in people's production and life now. [0003] With the development of LED technology, LED display screens made of LED light sources have been widely used by people. LED display screens are a display method that controls semiconductor light-emitting diodes, which are generally composed of many light-emitting diodes. , Rely on the LED light source ligh...
