[0026] The present invention will be further described in detail below with reference to specific embodiments.

[0027] First embodiment:

[0028] For racks where cold air is less likely to leak, see Figure 1 The system includes a cabinet 1, which has nine mounting positions 100 arranged vertically (only the fifth mounting position from the bottom is shown as a dashed line in the diagram). Each mounting position 100 has two threaded holes 101 on its left and right sides. See [link / details]. Figure 2 When the operator installs server 2 on cabinet 1, first place server 2 into the installation position 100, align the four mounting holes 202 on the left and right sides of server 2 with the four threaded holes 101 on the left and right sides of the installation position 100, and then use four bolts 3 to pass through the four mounting holes 202 and screw them into the four threaded holes 101, thus installing server 2 on the installation position 100.

[0029] See Figure 3, the front end of the cabinet body 1 is provided with an air inlet 103 and is installed with a front cabinet door 104, the middle part of the front cabinet door 104 is a mesh part 1040, and the mesh part 1040 of the front cabinet door 104 is aligned with the air inlet 103 in the closed state. The rear end of the cabinet body 1 is provided with an air outlet 105 and is installed with a rear cabinet door 106, the middle part of the rear cabinet door 106 is a mesh part 1060, and the mesh part 1060 of the rear cabinet door 106 is aligned with the air outlet 105 in the closed state. The cabinet body 1 is placed in a machine room, and the cold air in the machine room passes through the mesh part 1040 of the front cabinet door 104, enters the cabinet body 1 through the air inlet 103, absorbs the heat generated by the server 2 to become hot air, and the hot air is discharged to the outside of the cabinet body 1 through the mesh part 1060 of the rear cabinet door 106.

[0030] See Figure 4 and Figure 8 , the left wall of the cabinet body 1 is provided with a left mounting cavity 11, five support plates 12 are installed in the left mounting cavity 11 in parallel from top to bottom, five first vertical rotating shafts 41 which are the same in structure are respectively installed on the five support plates 12, and five first curtain barriers 51 which are the same in structure are respectively wound on the five first vertical rotating shafts 41, the five first curtain barriers 51 are respectively corresponding to the first, third, fifth, seventh and ninth installation positions 100 from bottom to top in height, and can be respectively expanded horizontally to the right and blocked in front of the five installation positions 100. Figure 8 , the right wall of the cabinet body 1 is provided with a right mounting cavity 15, four support plates 12 are installed in the right mounting cavity 15 in parallel from top to bottom, four second vertical rotating shafts 42 (see Figure 5 , the first vertical rotating shaft 41) which are the same in structure are respectively installed on the four support plates 12, and four second curtain barriers 52 which are the same in structure are respectively wound on the four second vertical rotating shafts 42, the four second curtain barriers 52 are respectively corresponding to the second, fourth, sixth and eighth installation positions 100 from bottom to top in height, and can be respectively expanded horizontally to the left and blocked in front of the installation positions 100. See Figure 6 , in the case that the cabinet 1 is not fully loaded, for example, in the case that the fifth installation position 100 is an empty installation position, the operator only needs to make the first curtain barrier 51 corresponding to the installation position 100 expand horizontally to the right and block in front of the empty fifth installation position 100, as shown in Figure 4 , so that the first curtain barrier 51 can block the cold air, effectively prevent the cold air from directly entering the empty fifth installation position 100 from the air inlet 103, and effectively avoid the cooling efficiency and energy waste caused by the leakage of the cold air. See

[0031] See Figure 8The right cavity wall 111 of the left mounting cavity 11 has an opening 112 at its front end, extending laterally to the right to the front of the fifth mounting position 100. The free end 511 of the first curtain 51 extends laterally to the right from this opening 112 to the outside of the left mounting cavity 11. An anti-shrinkage block 512 is attached to it. The anti-shrinkage block 512 is larger than the opening 112, thus preventing it from retracting laterally into the left mounting cavity 11. The free end 511 of the first curtain 51 and the anti-shrinkage block 512 are located on the left side of the fifth mounting position 100 and do not normally affect the installation of the server 2. The anti-shrinkage block 512 is "U"-shaped and also serves as a buckle, with a latch 513 in its middle. The front wall of the cabinet 1 is like... Figure 7 As shown, there is a corresponding locking block 13 protruding forward. Figure 1 This card block 13 is located to the right of the 5th installation slot 100 and will not normally affect the installation of server 2. See Figure 8 and Figure 9 The left front wall of cabinet 1 is recessed to form a concave cavity 14 with its opening facing forward. An operating opening 116 is located on the front wall of the left mounting cavity 11. This operating opening 116 is aligned with the bottom 411 of the first vertical rotating shaft 41 and connects forward to the concave cavity 14. The bottom 411 of the first vertical rotating shaft 41 is wider than its top 410. Its bottom 411 protrudes forward through the operating opening 116 to the outside of the left mounting cavity 11 and extends into the concave cavity 14. When the front cabinet door 104 is closed, its frame portion 1041 also serves as the door to the concave cavity 14, sealing the opening of the concave cavity 14.

[0032] See Figure 8 and Figure 9 The free end 511 of the first curtain 51 serves as the curtain unfolding operation part. When the fifth installation position 100 is empty, the operator opens the front cabinet door 104 to expose the anti-shrinkage block 512 on the free end 511 of the first curtain 51. Then, the operator grasps the anti-shrinkage block 512 and pulls it horizontally to the right to the right side of the installation position 100, thereby pulling the first curtain 51 horizontally out and unfolding it horizontally. During this process, the first curtain 51 drives the first vertical rotating shaft 41 to rotate. The anti-shrinkage block 512 serves as a snap-fit ​​fixing part. The operator aligns the snap-fit ​​513 of the anti-shrinkage block 512 with the snap-fit ​​block 13 on the cabinet body 1, and then lets the anti-shrinkage block 512... Figure 7 As shown, the first curtain 51 is inserted backward into the locking block 13. During this process, the locking block 13 is inserted forward into the locking slot 513, thus engaging and fixing it together with the anti-shrinkage block 512. With the front cabinet door 104 open, the recessed cavity 14 faces forward and connects to the outside, and the bottom 411 of the first vertical rotating shaft 41, serving as the curtain retraction operation part, is exposed forward. If the length of the first curtain 51 pulled out exceeds the required length, the operator manually rotates the bottom 411 of the first vertical rotating shaft 41 in the opposite direction to retract the excess portion of the first curtain 51. The first curtain 51 in its horizontally unfolded state is as follows... Figure 6 and Figure 9As shown, the barrier positioned in front of the vacant fifth mounting position 100 blocks the cold air, effectively preventing cold air from directly entering the vacant fifth mounting position 100 from the air inlet 103. See Figure 8 and Figure 9 The opening 112 of the right cavity wall of the left mounting cavity 11 matches the vertical cross-sectional shape of the first curtain 51. Therefore, the first curtain 51 can effectively seal the opening 112 by passing through it, preventing cold air from passing through the opening 112. The frame portion 1041 of the front cabinet door 104 normally seals the opening of the recessed cavity 14, making it difficult for cold air to enter the recessed cavity 14.

[0033] See Figure 7 and Figure 9 When the first curtain 51 needs to be retracted: the operator opens the front cabinet door 104, then grabs the anti-shrink block 512 on the free end 511 of the first curtain 51, and pulls the anti-shrink block 512 forward to release the engagement between the anti-shrink block 512 and the locking block 13. Then, the operator rotates the bottom 411 of the first vertical shaft 41 in the opposite direction to retract the unfolded first curtain 51.

[0034] See Figure 8 and Figure 9 The cabinet has two recessed cavities 14, one on the left and one on the right. An opening 112, an operating port 116, and a locking block 13 together form a curtain-blocking structure. The cabinet 1 has a total of nine curtain-blocking structures, corresponding to nine curtains 51 and 52 (see...). Figure 4 Since the specific correspondence between one of the curtain-blocking structures and one of the curtain-blocking structures 51 has been described in detail above, the specific correspondence between the remaining eight curtain-blocking structures and the eight curtain-blocking structures 51 and 52 is also described above and will not be repeated here.

[0035] This embodiment is shown in Figure 7 The free end 511 of the first curtain 51 is attached with an anti-shrinkage block 512. When the first curtain 51 is unfolded, the anti-shrinkage block 512 is snapped and fixed to the cabinet 1. In other embodiments, the free end 511 of the first curtain 51 is provided with a magnet. When the first curtain 51 is unfolded, the magnet is magnetically fixed to the cabinet 1.

[0036] Second embodiment:

[0037] The second embodiment is largely the same as the first embodiment, except that:

[0038] See the second embodiment. Figure 10The first transverse guide rail 61 is used to replace the support plate 12 and the first vertical pivot 41 of the first embodiment, and the second transverse guide rail 62 is used to replace the support plate 12 and the second vertical pivot 42 of the first embodiment. The first and second transverse guide rails 61 and 62 are identical in structure but opposite in direction, and the first and second curtain barriers 51 and 52 are identical in structure but opposite in direction. Taking the first curtain barrier 51 corresponding to the fifth mounting position 100 and the first transverse guide rail 61 corresponding to the first curtain barrier 51 as an example, see Figure 11 and Figure 12 The first curtain barrier 51 comprises seven curtain plates 58 arranged along the first transverse guide rail 61. Each two adjacent curtain plates 58 are hinged together, and the hinge shaft 59 extends into the first transverse guide rail 61 to be guided by the first transverse guide rail 61, so that the first curtain barrier 51 can slide transversely along the first transverse guide rail 61. The first transverse guide rail 61 is located in the left mounting cavity 11 and is mounted on the left wall of the cabinet body 1. The front end portion 611 of the first transverse guide rail 61 faces right, guiding the first curtain barrier 51 to the opening 112, that is, guiding the first curtain barrier 51 to the front side of the fifth mounting position 100. The first end portion 511 of the first curtain barrier 51 corresponds to the free end portion 511 of the first curtain barrier 51 in the first embodiment, which serves as a curtain unfolding operation portion, extends to the right side of the front end portion 611 of the first transverse guide rail 61 and extends out of the left mounting cavity 11 to the right of the opening 112, and is provided with a shrink-proof block 512. In the state that the fifth mounting position 100 is empty, the operator opens the front cabinet door 104 to expose the first end portion 511 of the first curtain barrier 51, and pulls the first end portion 511 of the first curtain barrier 51 to the right to pull out the first curtain barrier 51 to the right and unfold the first curtain barrier 51 to the front side of the fifth mounting position 100, and then fixes the shrink-proof block 512 and the clamping block 13. During this process, the operator needs to pay attention to not accidentally pull out the second end portion 515 of the first curtain barrier 51, and ensure that the second end portion 515 of the first curtain barrier 51 is located on the front end portion 611 of the first transverse guide rail 61 in the unfolded state of the first curtain barrier 51. When the operator needs to fold the first curtain barrier 51, the operator first releases the clamping fixation between the shrink-proof block 512 of the first end portion 511 of the first curtain barrier 51 and the clamping block 13, and then sends the first curtain barrier 51 into the left mounting cavity 11 from the opening 112, and makes the second end portion 515 of the first curtain barrier 51 slide transversely along the first transverse guide rail 61 to the rear end portion 612 thereof until the first curtain barrier 51 is transversely folded.

[0039] The above description is only an embodiment of the present application, and does not limit the scope of patent protection. Those skilled in the art can make non-essential changes or substitutions based on the present application, and still fall within the scope of patent protection.
