How to effectively dissipate heat for outdoor LED display screens

The heat exchange area between heating electronic components and cold air, as well as the temperature difference between heating electronic components and cold air, directly affect the heat dissipation effect. This involves the design of the air volume and air duct for entering the LED display box. When designing ventilation ducts, it is advisable to use straight pipes to transport air and avoid using pipes with sharp turns and bends. Ventilation ducts should avoid sudden expansion or contraction. The expansion angle should not exceed 20o, and the contraction cone angle should not exceed 60o. Ventilation ducts should be sealed as much as possible, and all overlaps should follow the direction of flow.
