Multi-channel passive radiator

The multi-channel passive radiator comprises a radiator body, an air flow channel is formed in the radiator body, an air inlet is formed in the bottom of the radiator body, an air outlet is formed in the top of the radiator body, and the two ends of the air flow channel communicate with the air inlet and the air outlet correspondingly; a plurality of electronic equipment installation spaces are sequentially arranged in the radiator body in the circulation direction of the air flow channel. The heat exchanger is suitable for a multi-layer stacking equipment system, and the external heat exchange efficiency of the system can be effectively improved on the premise that the power consumption of the system is not increased and vibration is not brought. 本申请公开了一种多通道被动散热器，包括：散热器本体，散热器本体内设置有空气流道，散热器本体的底部设置有进气口，散热器本体的顶部设置有出气口，空气流道的两端分别与进气口和出气口连通，散热器本体内沿空气流道的流通方向依次设置有多个电子设备安装空间。本发明适用于多层堆叠设备系统，能够在不增加系统功耗和不带来震动的前提下，有效提高系统对外的热交换效率。
