When the different numbers of drawer bodies 400 are used, the air inlets 120 corresponding to the drawer bodies 400 are opened, and air flows into the cabinet 100 from the opened air inlets 120, cools the drawer bodies 400, and then flows out from the corresponding air outlets 130. The other unopened air inlets 120 remain closed, so that the cross-sectional area of air flowing in the cabinet 100 is reduced, the air flow rate flowing through the drawer body 400 per unit air volume is increased, and different cooling efficiencies are effectively improved, so that energy sources are effectively saved. It is envisioned that, to reduce air leakage, each of the insertion openings 110 may be provided with a baffle,

Referring to fig. 1 to 5, it will be appreciated that the air distribution device 200 includes a plurality of cover plates 220, the cover plates 220 are larger than the air inlets 120 in size so that the cover plates 220 can close the air inlets 120, the upper ends of the cover plates 220 are hinged to the upper ends of the corresponding air inlets 120 and located in the air inlet covers 210, the cover plates 220 are used for closing the corresponding air inlets 120, and the drawer body 400 can push the cover plates 220 to rotate upwards to open the corresponding air inlets 120 during the process of being inserted into the corresponding insertion openings 110. The cover plate 220 moves to a vertical state under the action of gravity and closes the air inlet 120. Because the cover plate 220 is located at the outer side of the cabinet body 100, the pressure difference received by the two sides of the cover plate 220 in the vertical state can make the cover plate 220 cling to the outer side wall of the cabinet body 100, which is beneficial to improving the tightness between the cover plate 220 and the air inlet 120.

Referring to fig. 1 to 5, it can be understood that the upper end of the air inlet 120 is hinged with a linkage device 500, and the linkage device 500 is partially located in the cabinet 100, and when the linkage device 500 moves, the linkage device can abut against one side of the cover plate 220 close to the cabinet to push the cover plate 220 to rotate. The drawer body 400 can push the linkage device 500 to rotate during the process of being inserted into the corresponding insertion opening 110, so as to automatically push the cover plate 220 to open the corresponding air inlet 120. Opening the air inlet 120 by using the linkage device 500 realizes the function of automatically adjusting the opening and closing of the air inlet 120 according to the position of the inserted drawer body 400, so that the heat dissipation effect of the drawer body 400 is better.

Referring to fig. 1 to 5, it can be understood that the linkage 500 includes a rotating shaft 510, a transmission part 520, and an actuating part 530, the rotating shaft 510 is hinged to the upper end of the air inlet 120, the rotating shaft 510 extends along the front-rear direction, both the actuating part 530 and the transmission part 520 are welded to the rotating shaft 510, the actuating part 530 can rotate to abut against the cover plate 220 to drive the cover plate 220 to rotate and open, the transmission part 520 is located inside the cabinet 100, the drawer body 400 can push the transmission part 520 to rotate around the rotating shaft 510 in the process of being embedded into the corresponding insertion opening 110, the transmission part 520 is a cylinder which is obliquely arranged, and when the drawer body 400 moves backwards, the transmission part 520 drives the rotating shaft 510 to rotate due to the oblique arrangement of the transmission part 520, and the contact point between the drawer body 400 and the transmission part 520 also moves backwards until the cover plate 220 is opened.

Referring to fig. 1 to 5, it can be understood that an air outlet cover 600 is welded to the right side of the cabinet 100, and an air outlet pipe 610 for exhausting air in the cabinet 100 is provided to the air outlet cover 600.

Under the condition of unchanged air inlet quantity, the air flow speed of the cooling drawer body 400 is effectively improved, and the heat dissipation effect is improved.

The embodiments of the present utility model have been described in detail with reference to the accompanying drawings, but the present utility model is not limited to the above embodiments, and various changes can be made within the knowledge of one of ordinary skill in the art without departing from the spirit of the present utility model.
