[0002] IT equipment is centrally managed in the computer room. The heat generated by each device during operation may cause equipment failure. The upward delivery of cold air can effectively dissipate heat for the cabinets in the computer room. Specifically, cold air is blown out from the precision air conditioner in the computer room. The cold air is transported to the inside of the cabinet through the air intake duct deployed above the cabinet and through the cold air inlet on the top of the cabinet to dissipate heat for the equipment. Multiple identical cabinets are used in the computer room. The cold air is uniformly supplied to each cabinet by the same air conditioner, and each cabinet receives the cold air through its own cold air inlet. Some cabinets store equipment that generates less heat, while some cabinets store equipment that generates more heat. The former receives the same amount of cold air as the latter, resulting in waste, or even causing the latter to not get enough cold air. Utility Model Content

DETAILED DESCRIPTION
[0019] The present invention is further described in detail below in conjunction with specific implementation methods.
[0020] Cabinet 1 Figure 1As shown, the top surface is provided with a cold air inlet 2, and the bottom of the cabinet 1 is provided with a heat dissipation hole 3. The cold air is blown from the air intake duct of the air conditioner into the cabinet 1 to cool down the equipment and then becomes warm air, which is discharged through the heat dissipation hole 3 at the bottom of the cabinet 1. The top surface of the cabinet 1 is provided with front and rear longitudinal guide rails 4 on both sides of the cold air inlet 2. The cold air inlet 2 is covered with two sliding cover plates 5, namely the front sliding cover plate 51 and the rear sliding cover plate 52. Figure 2 As shown, the sliding cover plate 5 is provided with feet 6 on the left and right sides, and the feet 6 are transversely embedded in the guide rail 4. The cold air inlet 2 is exposed between the two sliding cover plates 51 and 52. The installer operates the sliding cover plate 5 to slide along the guide rail 4 to adjust the size of the exposed area of the cold air inlet 2.
[0021] The guide rail is provided with six rear threaded through holes 41, 42, 43, 44, 45, 46 from front to back. The front sliding cover plate 51 is provided with a front threaded through hole 8 on the foot 6. Figure 3 In the state shown, the front sliding cover plate 51 has slid forward to the end along the guide rail 4, and the front threaded through hole 8 is aligned with the front rear threaded through hole 41; the rear sliding cover plate 52 is also provided with a front threaded through hole 8 on the right foot 6 at the front. Figure 3 In the state shown, the rear sliding cover plate 52 has slid backward along the guide rail 4 to the end, and the front threaded through hole 8 is aligned with the rear threaded through hole 46 at the end. In this state, the exposed area of the cold air inlet 2 is the largest, so the largest dustproof net 10 is selected and placed on the guide rail 4 to cover the cold air inlet 2. Figure 3 As shown, the dustproof net 10 has a front fixing threaded through hole 101 at the front corner and a rear fixing threaded through hole 102 at the rear corner. The distance from the front fixing threaded through hole 101 to the rear fixing threaded through hole 102 is equal to the distance from the rear threaded through hole 41 to the rear threaded through hole 46. The front fixing threaded through hole 101 is aligned with the rear threaded through hole 41, and the rear fixing threaded through hole 102 is aligned with the rear threaded through hole 46. Then, a hexagonal bolt is passed through the front fixing threaded through hole 101 of the dustproof net 10, the rear threaded through hole 41 of the guide rail 4 and the front threaded through hole 8 of the sliding cover plate 5 from top to bottom in sequence. Then, a hexagonal bolt is passed through the rear fixing threaded through hole 102 of the dustproof net 10, the rear threaded through hole 46 of the guide rail 4 and the front threaded through hole 8 of the sliding cover plate 5 from top to bottom in sequence, and the dustproof net 10 is fixed to the guide rail 4 and the foot 6.
[0022] If it is necessary to reduce the exposed area of the cold air inlet 2, the front sliding cover plate 51 is slid forward to align the front threaded through hole 8 with the rear threaded through hole 42, and the rear sliding cover plate 52 is slid backward to align the front threaded through hole 8 with the rear threaded through hole 45. In this state, the exposed area of the cold air inlet 2 is medium, so a medium-sized dustproof net is selected, the distance between the front fixed threaded through hole and the rear fixed threaded through hole of the dustproof net is equal to the distance between the rear threaded through hole 42 and the rear threaded through hole 45, the front fixed threaded through hole is aligned with the rear threaded through hole 42, the rear fixed threaded through hole 102 is aligned with the rear threaded through hole 45, and then the hexagonal bolt is passed through the front fixed threaded through hole of the dustproof net, the rear threaded through hole 42 of the guide rail 4 and the front threaded through hole 8 of the sliding cover plate 5 from top to bottom in sequence, and the hexagonal bolt is passed through the rear fixed threaded through hole of the dustproof net, the rear threaded through hole 45 of the guide rail 4 and the front threaded through hole 8 of the sliding cover plate 5 from top to bottom in sequence, and the medium-sized dustproof net is fixed on the guide rail 4 and the foot 6.
[0023] If the exposed area of the cold air inlet 2 needs to be adjusted to the minimum, the front sliding cover plate 51 is slid forward again to align the threaded through hole 8 with the rear threaded through hole 43, and the rear sliding cover plate 52 is slid backward again to align the front threaded through hole 8 with the rear quasi-threaded through hole 44. In this state, the exposed area of the cold air inlet 2 is the smallest, so the smallest dustproof net is selected, the distance from the front fixed threaded through hole to the rear fixed threaded through hole of the dustproof net is equal to the distance from the rear threaded through hole 43 to the rear threaded through hole 44, the front fixed threaded through hole is aligned with the rear threaded through hole 43, and the rear fixed threaded through hole is aligned with the rear quasi-threaded through hole 44. Use hexagonal bolts to pass through the front fixed threaded through hole of the dustproof net, the rear threaded through hole 43 of the guide rail 4, and the front threaded through hole 8 of the sliding cover plate 5 from top to bottom in sequence; use hexagonal bolts to pass through the rear fixed threaded through hole, then through the rear threaded through hole 44, and then through the front threaded through hole 8, and the smallest dustproof net is fixed on the guide rail 4 and the foot 6.
[0024] When cold air passes through the space between the dust screen 10 and the cold air inlet 2, it is easy to leak forward or backward. For this reason, a transverse sealing portion 7 is extended upward from the rear edge of the front sliding cover plate 51, and a transverse sealing portion 7 is also extended upward from the front edge of the rear sliding cover plate 52. The top surface of the sealing portion 7 is flush with the top surface of the guide rail 4, plugging the gap between the dust screen and the cold air inlet 2 to prevent cold air from leaking out.
[0025] like Figure 4 As shown, the guide rail 4 has positioning protrusions 9 extending downward on both sides of the rear threaded through holes 41, 42, 43, 44, 45, and 46, and the sliding cover plate 5 has positioning grooves 11 correspondingly opened on both sides of the front threaded through holes 8. The positioning protrusions 9 of the guide rail 4 are embedded in the positioning grooves 11 of the sliding cover plate 5, so that the front threaded through holes 8 of the sliding cover plate 5 are aligned with the rear threaded through holes of the guide rail 4 and will not deviate left or right.
[0026] The above is only an implementation method of the invention, and does not limit the scope of patent protection. Those skilled in the art can make non-substantial changes or substitutions based on the invention, which still fall within the scope of patent protection.
