A network device includes a shelf in which a first accommodation area, a second accommodation area, a first channel, and a second channel are disposed. 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. A first 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. A second 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. |

1. A network device, comprising:
a shelf, wherein a first accommodation area, a second accommodation area, a first channel, and a second channel are disposed in the shelf, wherein the first accommodation area and the second accommodation area are close to a front end and a rear end of the shelf respectively and communicate with each other, wherein the first channel and the second channel are separately located on two sides of the second accommodation area, wherein the first channel and the second channel are both isolated from the first accommodation area and the second accommodation area, and wherein a third channel is further disposed in the shelf; at least one front board module, wherein the front board module is disposed in the first accommodation area; at least one rear board module, wherein the rear board module is disposed in the second accommodation area, wherein the front board module and the rear board module are electrically connected and are distributed in the shelf in an orthogonal manner, wherein the third channel is disposed between two adjacent rear board modules, and wherein the third channel communicates with the first accommodation area; a first fan, wherein the first fan and the second fan are both disposed at the rear end of the shelf, wherein the first fan faces the third channel, wherein a first airflow sequentially passes, from the 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; and a second fan, wherein the second fan faces the second channel, wherein a second 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 wherein the first heat dissipation channel and the second heat dissipation channel are independent of each other. |
