[0001] The utility model relates to the technical field of power equipment, in particular to a refrigeration and cooling device for a cabinet in a data center computer room. Background Technique

[0002] The cabinet in the data center computer room is an important part of the data center infrastructure. It is a physical device or container specifically designed for storing, installing, and managing servers, network devices, storage devices, and other key information technology devices. Since the electrical components inside it generate heat during use, if the heat is not discharged in time, it will cause the temperature inside the cabinet to rise, thereby affecting the performance, stability, and lifespan of the devices. However, there are still certain deficiencies in the existing refrigeration and cooling devices inside the cabinet when in use.

[0003] For example, the cabinet with a cooling function disclosed in CN206118295U drives the electric crossbar to move to the heating position, enabling the cooling fan to dissipate heat, thereby improving the heat dissipation performance of the cabinet, reducing the probability of overheat alarm of the cabinet, and ensuring the normal operation of the computer room. However, the electrical components are usually fixedly installed on the fixing parts inside the cabinet, and the heat will be transmitted to the fixing parts, resulting in heat concentration in some areas inside the cabinet while other areas are relatively cool. Even if the cooling fan can strengthen heat dissipation for specific positions, the overall heat dissipation effect may still be uneven. At the same time, it is not convenient to adjust the installation position of the electrical components according to the situation, increasing the difficulty and time cost of maintenance.

[0004] Therefore, we propose a refrigeration and cooling device for a cabinet in a data center computer room to solve the problems mentioned above. Content of the Utility Model

[0013] Preferably, the side plate is arranged in an arc shape, a groove is formed at one end of the side plate close to the first filter screen, and the groove in the middle of the side plate is communicated with the air inlet pipe through a pipeline.

[0014] Preferably, two exhaust holes are symmetrically arranged with respect to the cabinet body, and the exhaust holes are aligned with the air outlet holes.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: The refrigeration and cooling device for the data center computer room cabinet can quickly disassemble the placing plate, facilitate adjusting the position and quantity of the placing plate according to the actual situation, thereby maximizing the utilization of the space inside the cabinet, reducing space waste, and simultaneously can quickly take away the heat inside the cabinet, keep the equipment inside the cabinet operating within a suitable temperature range, and avoid the decline in equipment performance or failure caused by high temperature. The specific content is as follows:

[0016] 1. There is a fixing frame and a clamping block. By fixing the fixing frame in the cabinet with bolts, the fixing frame can be quickly installed. Since there are multiple sliding grooves on the fixing frame, when installing the placement board, the placement board can be slid into the corresponding sliding groove according to the actual situation. Then, press the clamping block, so that the clamping block slides along the inner wall of the placement board while squeezing the compression spring to contract. Then, completely immerse the placement board into the sliding groove, so that the clamping block is aligned with the clamping groove.

At this time, turn on the micro motor, so that the micro motor drives the exhaust fan to rotate, thereby exhausting the temperature in the cabinet. Then, the outside air will enter the adapter sleeve through the first filter, and then enter the cabinet through the adapter sleeve. The gas in the cabinet will pass through the connecting pipe, so that the air circulates and dissipates heat. And a part of the gas in the adapter sleeve will enter the side plate and then enter the placement board through the pipeline, so that it circulates in the placement board, driving the heat of the placement board, effectively reducing the temperature inside the cabinet and protecting the electrical components from high-temperature damage.

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] Embodiment 1: Please refer to Figures 1 - 4 As shown, the present utility model provides a technical solution: a refrigeration and cooling device for a cabinet in a data center computer room, including a cabinet body 1, and a cabinet door 2 is hinged to the outside of the cabinet body 1.

[0025] With the setting of the cabinet body 1 in this technical solution, during use, first place the cabinet body 1 in a designated area, then rotate to open the cabinet door 2, and place the equipment in the data center computer room in the cabinet as required, and carry out wiring work to ensure that the equipment is fixed firmly and the wiring is neat and orderly. After installation, rotate to close the cabinet door 2.

[0026] Embodiment 2: The technical content disclosed in this embodiment is an improvement based on the above Embodiment 1. The existing one is not convenient to adjust the installation position of electrical components according to the situation, increasing the difficulty and time cost of maintenance. This technical solution is as Figure 2 and Figure 3 As shown, an installation component of a cabinet refrigeration device is disclosed. A fixing frame 3 is arranged in the cabinet body 1. An air inlet hole 102 is opened on the cabinet body 1 above the fixing frame 3, and a chute 301 is opened on the fixing frame 3. An air outlet hole 302 is opened on the side wall of the fixing frame 3 below the chute 301. Card slots 303 are opened on the upper and lower sides of the chute 301. A placement plate 4 is arranged in the chute 301. A clamping block 5 is movably connected in the placement plate 4. Two fixing frames 3 are symmetrically arranged with respect to the cabinet body 1, and the chute 301 on the fixing frame 3 is opened on the side walls of the two fixing frames 3 facing each other. The two ends of the placement plate 4 are respectively slidably arranged in the two chutes 301. A plurality of chutes 301 are arranged in an array along the vertical axis of the fixing frame 3. The upper and lower ends of the connecting pipe 7 in the placement plate 4 both penetrate and extend out of the placement plate 4, and a plurality of connecting pipes 7 are arranged in an array. The cavity 6 in the placement plate 4 is communicated with the air inlet pipe 8 and the air outlet pipe 9. The clamping block 5 is arranged in an "L" shape, and two clamping blocks 5 are symmetrically arranged with respect to the placement plate 4. Compression springs 501 are connected between the two clamping blocks 5 and the placement plate 4. The clamping block 5 and the placement plate 4 form an elastic telescopic structure through the compression spring 501, and the clamping block 5 is aligned with the card slot 303.

[0027] In this technical solution, as Figure 2As shown in the figure, by means of the setting of the clamping block 5, when the placing plate 4 is inserted into the sliding groove 301, the clamping block 5 will be inserted into the clamping groove 303 under the elastic action of the compression spring 501, so as to limit and fix the placing plate 4 and prevent the placing plate 4 from shifting and shaking during use, greatly improving the convenience of use.

[0028] It adopts the technical solution as Figure 3 shown. First, place the fixing frame 3 in the cabinet body 1 so that the air outlet holes 302 on the fixing frame 3 are aligned with the exhaust holes 14. Then, fix the fixing frame 3 in the cabinet body 1 through bolts. After the installation is completed, hold the placing plate 4 and slide it into the sliding groove 301. At the same time, press the clamping block 5 so that the clamping block 5 squeezes the compression spring 501 to contract. When the placing plate 4 is completely immersed in the sliding groove 301, at this time, the clamping block 5 is aligned with the clamping groove 303. After releasing the pressed clamping block 5, the clamping block 5 will be inserted into the clamping groove 303 under the elastic action of the compression spring 501, thereby fixing the placing plate 4 on the fixing frame 3. When it is necessary to adjust the placing plate 4, only need to press the clamping block 5 so that the clamping block 5 squeezes the compression spring 501 to contract and separates from the clamping groove 303 at the same time, and then pull out the placing plate 4.

[0029] Embodiment 3: The technical content disclosed in this embodiment is a further improvement based on the above-mentioned Embodiment 1 and Embodiment 2. Since electrical components are usually fixedly installed on the fixing parts in the cabinet, heat will be transmitted to the fixing parts, resulting in heat concentration in some areas of the cabinet and relatively cool in other areas. Even if the cooling fan can strengthen the heat dissipation for specific positions, the overall heat dissipation effect may still be uneven. To further solve this technical problem, the technical solution of this embodiment is as Figure 1 and Figure 4 shown, which discloses a cooling component of the cabinet cooling device. A cavity 6 is opened in the middle of the placing plate 4 provided, and a communicating pipe 7 is fixedly connected in the cavity 6. An air inlet pipe 8 is fixedly connected to the upper end of the placing plate 4, and an air outlet pipe 9 is fixedly connected to the bottom end of the placing plate 4. An fixing plate 10 is fixedly connected to the outer wall of the cabinet body 1 above the air inlet hole 102, and an adapter sleeve 11 is threadedly connected in the fixing plate 10. A first filter screen 12 is fixedly connected in the adapter sleeve 11, and a side plate 13 is fixedly connected to the inner wall of the adapter sleeve 11 below the first filter screen 12. An exhaust hole 14 is opened on the side wall of the cabinet body 1, and a second filter screen 15 is fixedly connected in the exhaust hole 14. A bracket 16 is fixedly connected in the air outlet hole 302, and a micro motor 17 is fixedly connected to the bracket 16. And an exhaust fan 18 is fixedly connected to the output end of the micro motor 17. The side plate 13 is arranged in an arc structure, and a groove is opened at one end of the side plate 13 close to the first filter screen 12. And the groove in the middle of the side plate 13 is communicated with the air inlet pipe 8 through a pipeline. Two exhaust holes 14 are symmetrically arranged about the cabinet body 1, and the exhaust holes 14 are aligned with the air outlet holes 302.

[0030] In this technical solution, as Figure 1 shown, by means of the arrangement of the placement plate 4 and the connecting pipe 7, the gas entering the cabinet will enter the cavity 6, thereby taking away the heat of the placement plate 4, enabling the heat on the placement plate 4 to be quickly taken away by the gas, allowing the heat to dissipate more rapidly, and preventing the performance of the equipment from degrading or being damaged due to high temperature.

[0031] It adopts the technical solution as Figure 4 shown. When the electrical components in the cabinet are used for a long time, the temperature will rise, and then the heat will be transferred to the placement plate 4 in contact with it, causing the temperature of the placement plate 4 to be too high. At this time, the micro motor 17 is turned on, and the micro motor 17 drives the exhaust fan 18 to rotate, causing the exhaust fan 18 to drive the air flow in the cabinet to flow, and then discharge through the exhaust hole 14. Subsequently, the external gas will enter the adapter sleeve 11 through the first filter screen 12, then enter the cabinet through the adapter sleeve 11. Then, the gas entering the cabinet will pass through the connecting pipe 7 and finally be discharged through the exhaust hole 14. This process repeats for heat dissipation. At the same time, a part of the air flow in the adapter sleeve 11 will enter the groove in the side plate 13, enter the intake pipe 8 through the pipeline, and finally enter the cavity 6 through the intake pipe 8, enabling the air flow to circulate in the cavity 6 and be discharged through the outlet pipe 9, thereby driving the heat on the placement plate 4 and further dissipating heat.

[0032] The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0033] Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
