一种带有隐蔽式散热孔的LED显示屏外壳

Abstract

本实用新型公开了一种带有隐蔽式散热孔的LED显示屏外壳，包括：整体单元，其包括屏幕外壳和固定连接在屏幕外壳内的显示屏幕，所述屏幕外壳的背面固定连接有可拆卸的支座，进风单元，其包括开设在所述屏幕外壳底部的多个散热孔，排风单元，其包括固定连接在所述屏幕外壳背面顶部的导流罩，所述导流罩的顶部开设有用于出风的出风缺口，所述屏幕外壳的背面开设有与导流罩相连通的出风口。本实用新型通过将散热孔隐蔽设置于屏幕外壳底部，可从视觉上消除散热孔对外观的破坏，同时，屏幕外壳内部产生的热量经导流罩顶部的出风缺口定向向上排出，使热空气自然上升扩散，避免热量经墙壁扩散至屏幕外壳表面。
