A horizontal subrack includes a ventilation box, a fan box and a board area. The ventilation box is located on the top and/or at the bottom of the board area, and includes an air partition plate, an air inlet, and a first air outlet; the air partition plate is set inside the ventilation box, and divides the ventilation box into an air-in chamber and an air-out chamber; the fan box is installed in the air-in chamber, and a fan is installed on the fan box; the air inlet is set on the front wall of the ventilation box; and the first air outlet is set on the rear wall of the ventilation box. The board area includes board slots, an air-in duct and an air-out duct. The air-in duct is located on one side of the board slots, and the air-out duct is located on the other side of the board slots. The air-in duct is linked to the air-in chamber, and the air-out duct is linked to the air-out chamber. The horizontal subrack extends the trail between the fan box and the board area, improves the evenness of the air volume distributed to the slots of the horizontal subrack, and overcomes the bottleneck of enhancing the heat dissipation capability of the horizontal subrack.
