摘要： The present invention discloses a network device, including a shelf in which a first accommodation area, a second accommodation area, a first channel, and a second channel are disposed. The first channel and the second channel are located on two sides of the second accommodation area separately. A front board module and a rear board module are disposed at the first and second accommodation areas respectively. A third channel is formed between adjacent rear board modules or between the rear board module and the shelf. A first fan and a second fan are both disposed at a rear end of the shelf, the first fan faces the third channel, and the second fan faces the second channel. An airflow sequentially passes, from a front end of the shelf, through the front board module in the first accommodation area, the third channel, and the first fan to form a first heat dissipation channel, an airflow sequentially passes through the inside of the rear board module, the second channel, and the second fan after entering the first channel from the outside of the shelf, to form a second heat dissipation channel, and the first heat dissipation channel and the second heat dissipation channel are independent of each other. A heat dissipation air duct of the network device in the present invention is simple, which improves utilization of a fan, and enhances a heat dissipation capability.

摘要翻译： 本发明公开了一种网络设备，包括搁架，其中设置有第一容纳区域，第二容纳区域，第一通道和第二通道。 第一通道和第二通道分别位于第二容纳区域的两侧。 前板模块和后板模块分别设置在第一容纳区域和第二容纳区域处。 第三通道形成在相邻的后面板模块之间或后面板模块与搁架之间。 第一风扇和第二风扇都设置在搁板的后端，第一风扇面向第三通道，并且第二风扇面向第二通道。 气流依次从架子的前端穿过第一容纳区域中的前板模块，第三通道和第一风扇以形成第一散热通道，气流顺序地穿过后部内侧 第二通道和第二风扇在从搁板外部进入第一通道后形成第二散热通道，第一散热通道和第二散热通道相互独立。 本发明网络设备的散热风道简单，提高了风扇的利用率，增强了散热能力。
