Embodiments of present invention provide an air guiding subrack and a rack. The air guiding subrack (32) comprises an air inlet panel (21), a first partition board (22), a second partition board (23), and an air channel segmentation board (24). The air inlet panel (21) is disposed on one side of a door where an inlet hole of the rack is located. The first partition board (22) and the second partition board (23) face each other and are disposed at joints of an adjacent service subrack (31) and an air guiding subrack (32). The air channel segmentation board (24) takes one side of multiple sides where the air inlet panel (21) is not in contact with the first partition board (22) and the second partition board (23) as a starting side, and stretches to an ending side, wherein the ending side is disposed on one side of the door where an air outlet of the rack is located. Other sides of the air channel segmenting board (24) are in contact with the first partition board (22) and the second partition board (23). The sidewall of the rack close to the ending side differs from the side wall close to the starting side. With the embodiment of present invention, problems like small air inlet surface area, mutual baking of subracks and hot air backflow in a conventional subrack are effectively solved, and the heat radiation effect of the rack is substantially improved. |
