How to solve the design of outdoor full-color LED display cooling?
With the advent of hot summer, we can not stand the heat every day, let alone the working machinery and equipment. Outdoor LED displays are also more prone to heat, and high temperatures can cause the probability of failure of electronic components to increase rapidly, resulting in a decrease in the reliability of the LED display. In order for Led display to adapt to the high temperature environment can work properly, then manufacturers in the design of products should take more into account the design of this part of heat dissipation.
LED display box radiation design, there are several points to note:
1. the vent shall be mounted near the upper side of the case. The intake holes should be set on the lower side of the box, but not too low so as to prevent dirt and water from entering the box which is installed on the floor.
2. design to ensure that the intake and exhaust port away. Avoid repeated use of cooling air.
3. natural convection should be designed to aid forced convection. The air shall be circulating from the bottom of the box, and a dedicated air inlet or vent shall be used. The cooling air shall flow through the heating and electronic components, and the air flow shall be prevented from short circuited. The filter screen shall be installed in the air inlet and outlet to prevent sundries from entering the box.
4. fan installed in the system, due to structural limitations, the air inlet and outlet are often subject to a variety of barriers, and its performance curve will change. According to the actual experience, the fan inlet and outlet is best to have 40mm distance from the barrier. If there is space limitation, there should be at least 20mm.
5., to ensure that the direction of the radiator with the wind direction parallel, the radiator alveolus can not block the wind road.
The above is Hot Electronics Co.,Ltd of the outdoor LED display, in the production process of heat need to pay attention to a few points, hope to help everyone, welcome to call free consultation.
