一种高散热性能的功放音响

Abstract

本实用新型公开了一种高散热性能的功放音响，涉及功放音响技术领域，包括壳体、设置于壳体内部的控制电路板和散热风扇，所述壳体两侧设有可翻转的翻转散热板，所述翻转散热板与壳体之间通过传动翻转机构连接，所述壳体内部设有用于驱动传动翻转机构运行的驱动机构。本实用新型通过驱动机构带动传动翻转机构，使壳体两侧的翻转散热板打开形成进风口和出风口，且进风口处翻转散热板开口斜向下、出风口处开口斜向上，契合空气自然对流规律，配合内部散热风扇，大幅增加空气流通量，让大量外界冷空气精准流向控制电路板上的发热电子元器件，热空气快速排出，增强热交换效率，满足大功率功放音响高负荷运行时的散热需求。
