The Work in Heat Dissipation of Outdoor LED Display of the Summer
Heat electronic components and cold air heat exchange area, heat electronic components and cold air temperature difference, a direct impact on the cooling effect. This involves entering the led display box air volume size design, duct design. Ventilation duct design, as far as possible the use of straight pipeline to transport the air, to avoid the use of sharp turning and bending of the pipeline. Ventilation ducts should be avoided from sudden expansion or sudden contraction. The extension of the angle of not more than 20 °, shrink the cone angle should not be greater than 60 °. Ventilation pipes should be sealed as far as possible, all lap should be along the flow direction.
