[0034] The first cabinet 1 and the second cabinet 2 are both rectangular cabinets, and front doors and rear doors are provided on the front and rear middle surfaces of the first cabinet 1 and the second cabinet 2. A sealing strip layer is pasted between the first cabinet 1 and the second cabinet 2 to prevent cold air and noise from overflowing.

[0035] The first cabinet 1 and the second cabinet 2 are assembled with the buckle locks 4 , and the buckle locks 4 are arranged in four groups, which are respectively placed on the upper and lower parts of the two side surfaces between the first cabinet 1 and the second cabinet 2 .

[0036] The first cabinet 1 and the second cabinet 2 are fixedly connected with the double-row silencer wheels 5, the wire holes 6 and the condensate drain pipe 7. The double-row silencer wheels 5 are grouped into four groups and are respectively placed at the four corners of the bottom surfaces of the first cabinet 1 and the second cabinet 2.

[0040] Specifically, its structure consists of a first cabinet 1, a second cabinet 2, an air conditioning control display panel 3, a buckle lock 4, a double-row silencer wheel 5, a wire hole 6, a condensate drain pipe 7, a cooling fan 8, a spring buckle 9, a rack 10, a wire trough 11, a crossbeam 12, a serpentine spiral air duct structure 13, a suspended air conditioner 14, an air conditioner rear fan 15, a cold air input flange 15, a tray 16 and a PDU power supply 17 to form a double-layer air-conditioned noise reduction cabinet. The double-layer air-conditioned noise reduction cabinet is designed with an overall cabinet shell enclosed, and only a cooling fan 8 is provided on the upper rear part to minimize noise overflow, and a top-mounted compressor refrigeration suspended air conditioner 14 is built in to quickly and efficiently supply power to the PDU below. 17 The space of the server is cooled down. At the same time, two ceiling air conditioners 14 are built in the whole cabinet. The ceiling air conditioners 14 have a timer start and stop device through the air conditioning control display panel 3, and can alternately operate the cooling. The whole cabinet is formed by the first cabinet 1 and the second cabinet 2 to protect the internal structure. The inner walls of the first cabinet 1 and the second cabinet 2 are all attached with a sound-absorbing cotton layer. The first cabinet 1 and the second cabinet 2 are both upper and lower layer structures with a hole in the middle. The cold air outlet of the ceiling air conditioner 14 blows cold air downward to cool the cabinet carrying the server. The rear upper doors of the first cabinet 1 and the second cabinet 2 adopt a double-layer sandwich design to play the role of a duct box. The air conditioning control display panel 3 is used to monitor the first cabinet 1 and the first cabinet 2. The temperature inside the second cabinet 2 and the air start and stop temperature are set. The first cabinet 1 and the second cabinet 2 are combined and fixed together by the buckle lock 4. The double-row silencer wheel 5 makes the double-layer air-conditioned noise reduction cabinet movable as a whole and can be braked at any time. The network cable and power cable are placed in the first cabinet 1 and the second cabinet 2 through the wire hole 6. The condensed water drain pipe 7 is used to discharge the condensed water to the specified position. The waste heat generated by the suspended air conditioner 14 is discharged to the outside of the cabinet through the cooling fan 8. The cabinet door is opened and closed by the spring buckle hand 9, the server hanging ear is fixed by the rack 10, the network cable is tied by the wire trough 11 to arrange the wiring neatly, the vertical beam and the cabinet are connected by the crossbeam 12, and the serpentine spiral wind The channel structure 13 increases the physical distance of the noise out of the cabinet, and increases the passing area of ​​the noise through the silencer cotton. The air conditioner 14 is suspended for cooling and cooling. The cold air input flange 15 is used as a cold air channel connecting the upper and lower cabinets. The server equipment is loaded through the tray 16, and the equipment is powered by the PDU power supply 17. The double-layer air-conditioned noise reduction cabinet is designed with a closed cabinet. The cabinet has no heat dissipation holes, and only the rear upper door has a fan hole to block the sound from escaping the cabinet. At the same time, the cabinet is covered with silencer cotton, so that the noise is weakened and absorbed inside the cabinet; at the same time, two industrial refrigeration air conditioners for cooling large equipment are added inside, and a customized start-stop device is installed to alternately cool the equipment to solve the problem of equipment overheating;The rear door is designed with an air duct box, so that the waste heat generated by the air conditioner can be discharged from the cabinet in a winding manner in the top air duct box, which extends the distance of the sound directly overflowing from the cabinet by about 16 times. The final sound discharged is very small. The test results show that the equipment noise of 90-100 decibels can be reduced to about 45-50 decibels, which can be effectively reduced to half of the original. The first cabinet 1 and the second cabinet 2 are divided into two sections, the upper cabinet is the air conditioner space, and the lower cabinet is the server space, which can effectively prevent the heat generated by the air conditioner compressor from entering the cooling space of the server below, and allow the cooling capacity of the air conditioner to strongly cover the heat generated by the server. ;

[0041] Working principle: When in use, the first cabinet 1 and the second cabinet 2 need to be separated for use, but due to their large size, they cannot be carried into the elevator, so the first cabinet 1 and the second cabinet 2 are divided into two left and right cabinets. When arriving at the use site, the first cabinet 1 and the second cabinet 2 can be assembled with a hasp lock 4, with a sealing strip layer in the middle, and two hasp locks 4 on the upper and lower parts of the front and rear cabinet doors, respectively, which can allow the first cabinet 1 and the second cabinet 2 to be quickly and tightly connected, and tighten the sealing strip between the first cabinet 1 and the second cabinet 2 to prevent cold air from overflowing. There is no side door blocking the middle of the first cabinet 1 and the second cabinet 2, and the outermost two sides are closed with side doors, so that the air of the first cabinet 1 and the second cabinet 2 can flow through each other; in the middle of the upper and lower small cabinets, a ventilation cold air input flange 15 with a diameter of φ200mm is installed, and the cold air of the suspended air conditioner 14 passes through the cold air input flange 15, and the low-temperature cold air is sent into the interior of the server cabinet below. By strengthening the isolation of noise, the penetration rate of server noise is greatly reduced; the upper cover, base, front door, rear door, left door, and right door of the first cabinet 1 and the second cabinet 2, six inside the cabinet All directions are covered with sound-absorbing cotton, and high-density sound-absorbing cotton is used to absorb sound, which increases the sound-absorbing area. When the sound energy is transmitted into the interior of the sea porous material, it is quickly consumed by the vibration generated by the friction of the air in the small holes or a considerable part of the sound energy is converted into heat energy and absorbed, reducing the reflectivity and penetration rate. Through the design of the serpentine spiral air duct structure 13, the noise and the waste heat generated by the air conditioner are spiraled inside according to the length. After the noise is further weakened, the noise and the waste heat are discharged from the cabinet from the fan port on the top. The air outlet is designed at the back of the top, and the distance from the transmission to the human ear is far, so the noise will be much smaller. By installing two 3500w compressor refrigeration hoisting air conditioners 14, but since the air conditioning refrigeration compressor must stop working for a period of time to cool down after working for a period of time, in order to prevent the compressor from overheating and damage, the two air conditioners inside are respectively installed with timed start and customized shutdown electronic controllers, and the start and shutdown time is set. The two air conditioners are set to start and work in turn, with an interval of 1 hour. Each air conditioner works alternately for 12 hours a day. This solves the problem that the compressor cannot continue to cool down after stopping working. In this way, there is cold air input for cooling in the cabinet 24 hours a day. The cold air will pass through the air supply port between the upper and lower cabinets, and the low-temperature cold air will be transported to the lower cabinet where the server is located, which can quickly cool the server operation space. Since the air conditioner is also built-in inside the cabinet, the noise of the air conditioner is also weakened and blocked for the most part, effectively solving the problem that the existing technology cannot effectively reduce noise, the heat dissipation efficiency is poor, and the noise of the server is very loud when in use, and effectively improving the overall use efficiency.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
