The front and rear side plates of the server cabinet are respectively provided with a plurality of heat dissipation holes of the same size, and are at the top or bottom side of the server cabinet. An air conditioning device is provided. When in use, the cooling airflow blown by the air conditioner blows from the front of the server cabinet through the heat dissipation hole on the front side panel to the server and takes away the heat generated by the server to form a high temperature airflow from the server cabinet. The cooling holes on the rear side plate flow out. [0004] At present, the general server cabinets are relatively high, and the flow direction of the cooling airflow is sent up or up and down, and since the size of the heat dissipation holes on the front side of the server cabinet is the same, this will cause Servo 099141134 near air conditioning unit Form No. A0101 Page 4 / 18 pages 0992071578-0 201223392 The cooling airflow at the upper or lower server of the server cabinet is excessive, and is taken to the lower part of the server located away from the air conditioner or The cooling airflow at the upper server is less than 'favorable for proper distribution of cooling airflow and efficient heat dissipation.

[0011] The front side panel 14 has a rectangular plate shape and is sealed at a front end of the server cabinet 1〇. The front side panel 14 is provided with a plurality of venting holes 140, which are respectively arranged neatly along the lateral and longitudinal directions of the front side panel 14 in a plurality of rows and columns of venting holes 140 in the upper region of the front side panel 14. The total area 099141134 Form No. A0101 Page 6 of 18 0992071578-0 201223392 is different from the total area of the vent holes 14〇 of the lower area, that is, the aperture of the vent hole 〇4〇 located at the upper portion of the front side plate 14 is larger or smaller than The aperture of the venting opening 14 of the lower portion of the front side panel ^. In this embodiment, the aperture of the vent hole 4〇 is inclined upward and downward along the height direction of the front side plate 4. The plurality of vent holes 140 are sequentially divided into four parts along the height direction of the front side plate 14. Each portion includes a plurality of rows and a plurality of rows of venting holes 140, and the apertures of the venting holes 140 in the same portion are the same. The aperture of the venting holes 140 in each of the upper and lower portions of the front side plate 14 is smaller than the diameter of the venting holes 140. The aperture of the venting opening 140 of the other portion of the adjacent portion is not limited to the case of the embodiment, and the overall aperture may be from the top end of the front side panel 14 to the bottom thereof. The end gradually increases. Referring to FIG. 3, the inner side of the front side panel 14 is provided with a pivoting portion 18 corresponding to the fixing hole 171 of the supporting portion 170. The pivoting portion 18 includes a rotating shaft 180 extending perpendicularly from the inner side of the front side plate 14 toward the fixing hole i7l of the supporting portion 170, and a locking portion 182 provided at the end of the rotating shaft 180. The rotating shaft 180 is disposed in the fixing hole 1 该 of the supporting portion 170 , and the locking portion 182 is engaged with the fixing hole 171 Ο of the supporting portion 170 . The outer diameter of the rotating shaft 180 is smaller than the diameter of the fixing hole 171 of the supporting portion 170, so that the front side plate 14 can be rotated by the rotating sleeve 180 relative to the supporting portion 170 in the plane in which the front side plate 14 is located. The outer diameter of the locking portion 182 is larger than the fixing hole 171 ′ of the support portion 170 such that the front sleeve 14 does not fall out of the fixing hole 171 when the front side plate 14 is rotated relative to the support portion 170 . In a specific implementation, the front side plate 14 may be provided with only the rotating shaft 180, and after the rotating shaft 180 is inserted into the fixing hole 171 of the branch building 170, the rear end of the rotating shaft 180 may be crushed. The project has its end forming a snap portion 182. 099141134 Form No. A0101 Page 7 of 18 0995 201223392 [0012] The rear side panel 15 has a rectangular plate shape and is sealed at the rear end of the server cabinet 10. The rear side plate 15 is provided with a plurality of heat dissipation holes 150 having the same aperture. One side of the rear side panel 15 is pivotally disposed on the side panel 13 of the server cabinet 10, so that the rear side panel 15 can be opened and closed relative to the receiving space 16. When the rear side panel 15 is opened, the plurality of servers 20 are assembled from the rear side of the server cabinet 10 to the left and right side panels 13 of the server cabinet 10, and the front and rear sides of each server 20 are respectively A plurality of through holes 200 are provided, and a plurality of suction fans 202 are disposed inside (as shown in FIG. 4). [0013] Please also refer to FIG. 4, in use, when an air conditioner 30 is disposed at the top end of the front side of the server cabinet 10, the cold airflow blown by the air conditioner 30 is blown up and down, and the cold airflow is flowing. During the process, the ventilating hole 140 of the front side panel 14 is blown into the server cabinet 10, and then sucked through the through hole 20 of the front side through the suction fan 202 in each server 20 and passed through the rear side thereof. The through holes 200 are blown out to carry away the heat in each of the servos 20. The hot air flow blown by the through holes 200 on the rear side of each of the servos 20 is blown to the outside of the server cabinet 10 through the heat dissipation holes 150 of the rear side plate 15 of the server cabinet 10. Since the air conditioning unit 30 is disposed at the top end of the server cabinet 10, more cold airflow directly flows to the vicinity of the top end of the server cabinet 10, and the front side panel 14 of the server cabinet 10 is ventilated near its top end. The aperture 140 is smaller than the venting opening 140 near its bottom end to reduce the entry of a portion of the cold airflow at its top end position such that the portion of the cold air flow is downwardly along the front side panel 14 from the front side panel 14 near the bottom end of the venting opening. 140 enters, so that the cold airflow blown by the air conditioner 30 is uniformly entered into the server cabinet 10 from the top to the bottom, preventing the server 099141134 from being away from the air conditioner 30. Form No. A0101 Page 8 of 18 0992071578 -0 201223392 [0014] [0015] 2〇 The airflow blown is less and cannot be better dissipated, thereby improving the heat dissipation performance of the entire feeder cabinet 10. Please refer to FIG. 5 at the same time. Similarly, when the bottom end of the front side of the server side is provided with 4 (four) 30, the cold airflow blown by the air conditioner 3{) is ventilated from the bottom side of the front side panel 14 from the bottom. After being blown into the server cabinet 〇, the suction fan 2〇2 in each server 20 is sucked in through the through hole 200 on the front side thereof and blown through the through hole 200 on the rear side thereof, thereby The heat inside the feeder 20 is taken away. Since the air conditioning device 30 is disposed at the bottom end of the server cabinet 10, more cold airflow directly flows to the vicinity of the bottom end of the server cabinet 10 'because the front side panel 14 of the server cabinet 10 is relative to the support The portion 170 is rotated 'the front side plate 丨 4 of the server cabinet 1 旋转 can be rotated 180 degrees, so that the vent hole 14 该 of the front side plate 14 near the bottom end thereof is smaller than the vent hole 140 near the top end thereof, that is, the vent hole 140 The aperture has an increasing trend along the height direction of the front side panel 14, thereby reducing a portion of the cold airflow at the bottom end position of the server slot, so that the portion of the cold airflow is upwardly along the front side panel 14 The vent hole 140 of the side plate 14 near the top end thereof enters, so that the cold airflow blown by the air conditioner 30 is uniformly entered into the server cabinet 10 from the bottom to the top, thereby preventing the server 20 remote from the air conditioner 30 from blowing. There is less airflow and no better heat dissipation. In addition, when the server cabinet 10 is provided with some of the feeders 20 only near the top end or the bottom end thereof as needed, since the front side panel 14 can be rotated relative to the support portion 170, the front side panel 14 can be The portion of the vent hole 140 having a large aperture is rotated to the portion where the servo 20 is provided, so that the heat in the portion of the ventilator can be better distributed to the outside. In summary, the present invention meets the requirements of the invention patent, Form No. A0101, page 9 of 18, and is legally patented 0992071578-0 [0016] 201223392.
