[0041] Cabinets house equipment such as servers and switches, ensuring the proper functioning of the equipment. They are essential components of any data center. With the booming global data center industry and rapid socioeconomic growth, data center development and construction are expected to accelerate, creating a significant market opportunity for server cabinets. A multifunctional cabinet ensures optimal server operation. They systematically address the challenges of high-density heat dissipation, extensive cable routing, high-capacity power distribution, and comprehensive compatibility with racks and equipment from various manufacturers, enabling data centers to operate with high stability. A wide variety of cabinet styles can be found in major computer rooms. With the continuous advancements in the computer industry, the functionality of cabinets is increasing. Server cabinets must possess superior technical performance, including resistance to vibration, impact, and corrosion, to ensure stable and reliable operation of the equipment. They should also feature user-friendly and safety-critical features, facilitating operation, installation, and maintenance, while ensuring operator safety.

[0042] The internal environment of the cabinet is directly related to the safe operation of computer equipment. The temperature and cleanliness inside the cabinet are key factors affecting the efficient operation of the server. Currently, a large number of cabinets in use do not have the functions of cooling and dust removal.

[0043] In the related art, the cold air in the cold channel flows directly through the inside of the server through the pressure difference to cool the server. This method has two disadvantages. The first disadvantage is that when the air cleanliness in the computer room does not meet the requirements, there is a risk of dust accumulation when the air flows directly into the server, which may cause server failure. The second disadvantage is that the power for the flow of cold air is provided by the pressure of the computer room air supply outlet and the fan inside the server. The air flowing through the server in the cabinet close to the computer room air supply outlet has a high wind speed and a large air volume, while the air flowing through the server in the cabinet far away has a low wind speed and a small air volume. This will result in a good cooling effect for the server in the cabinet close to the air supply outlet, and a poor cooling effect for the cabinet far away, and low heat exchange efficiency of the server, which in turn affects the power consumption (PUE) of the data center.

[0044] In order to ensure the air cleanliness in the cabinet, improve the heat exchange efficiency of the server and reduce the PUE of the data center, the cabinet and computer room of the embodiment of the present invention are proposed.

[0045] The following combination Figure 1-Figure 5 The cabinet and the computer room of the embodiment of the present invention are described. In the embodiment of the present invention, the cabinet can be a server cabinet or other types of cabinets, and the type of the machine 200 in the present invention can be a server and a switch.

[0046] It is understandable that, referring to Figures 1 to 3In an embodiment of the present invention, the cabinet includes a cabinet body 100, a cabinet door 300 and an air supply mechanism 400. The cabinet body 100 is provided with a cavity 110, which is used to place the machine 200. The cabinet door 300 is movably connected to the cabinet body 100 to open or close the cavity 110. The air supply mechanism 400 is provided on the cabinet door 300 and connected to the cabinet door 300. The air supply mechanism 400 can at least provide power for cold air and guide the cold air to flow into the cavity 110.

[0047] According to the cabinet of the embodiment of the present invention, the air supply mechanism 400 provides power to guide the cold air into the cavity 110. The cold air flows into the cavity 110 and flows through the cavity 110 at an accelerated speed, thereby achieving the effect of cooling the machine 200 and reducing heat accumulation, thereby enhancing the heat exchange efficiency.

[0048] It should be noted that, in the embodiment of the present invention, the cabinet door 300 can be connected to the cabinet body 100 by rotation. Of course, in some embodiments, the cabinet door 300 can also be connected to the cabinet body 100 by sliding, which is not limited here.

[0049] Specifically, refer to Figures 1 to 3 In this embodiment of the utility model, a bracket 500 is provided on the cabinet door 300, and the air supply mechanism 400 includes at least one induced draft fan 410, which is provided on and connected to the bracket 500. Connecting the induced draft fan 410 via the bracket 500 ensures that the induced draft fan 410 is correctly positioned, thereby effectively guiding the flow of cold air into the chamber 110 and improving the efficiency and uniformity of air flow. Positioning the induced draft fan 410 on the bracket 500 effectively utilizes the space on the cabinet door 300, making the overall structure more compact and efficient.

[0050] It should be noted that in the related art, when the cold air from the air supply outlet of the machine room blows into the cold channel of the machine room, the flow direction of the cold air is 90 degrees to the air inlet direction of the cabinet, and the flow of cold air is blocked. However, the flow rate and wind speed of the cold air in the cabinet far away from the air inlet of the machine room are relatively small, which will cause the heat dissipation of the server and other machines 200 to be blocked and form heat accumulation, affecting the operating reliability of the server and other machines 200. The air flow organization of the cold air between the cabinets is poor, which will also lead to a waste of cold resources in the machine room. Therefore, in an embodiment of the present invention, after installing the induced fan 410 on the cabinet door 300 on the cold channel side of the cabinet, the induced fan 410 can improve the air flow organization in the cabinet, and by adjusting the frequency of the induced fan 410, the air supply volume of the cabinet can be adjusted according to the load of each cabinet, so as to ensure that each cabinet can obtain sufficient cooling capacity to cool down the server and other machines 200.

[0051] Specifically, refer to Figures 1 to 3In the embodiment of the present invention, there are multiple induced fans 410, and the multiple induced fans 410 are arranged at intervals along the height and width directions of the cabinet door 300. It can be understood that the height direction of the cabinet door 300 is the up-down direction.

[0052] With the above structure, multiple induced fans 410 arranged at intervals along the height and width directions can help ensure that the cold air is evenly distributed in the cavity 110, thereby improving the overall cooling efficiency; the setting of multiple induced fans 410 can cover a wider area, ensuring that the machines 200 in the entire cavity 110 can benefit from good air flow, thereby enhancing the cooling effect; the induced fans 410 arranged in the height and width directions can generate multi-directional air flow, which helps to avoid the emergence of hot spots and improve the overall heat exchange effect.

[0053] It is understandable that, referring to Figures 1 to 3 In this embodiment of the present invention, each induced air blower 410 is equipped with a corresponding fan frequency control button 600, which is used to adjust the speed of the corresponding induced air blower 410. With this structure, the air supply volume of each cabinet can be adjusted based on the load of each cabinet by adjusting the frequency of the induced air blower 410, thus ensuring that each cabinet receives sufficient cooling capacity to cool the servers and other machines 200.

[0054] It should be noted that, in the embodiment of the present invention, the induced fans 410 in each row can be controlled to start and stop the fans and to change the frequency by a unified switch.

[0055] Specifically, refer to Figures 1 to 3 In an embodiment of the utility model, the induced fan 410 is detachably connected to the bracket 500. The detachable connection makes the induced fan 410 easier to maintain and replace. If the fan needs to be cleaned or replaced, the above can simplify the operation and reduce maintenance time and cost. The number or position of the induced fan 410 can also be easily adjusted as needed, which increases the convenience of operation and enables maintenance personnel to more easily handle problems related to the induced fan 410 and reduce the difficulty of maintenance.

[0056] It should be noted that in this embodiment, the induced fan 410 is fixed to the bracket 500 by means of a nut connection. Of course, in some embodiments, the induced fan 410 can also be fixed to the bracket 500 by means of a snap connection, etc., which is not limited here. It should also be noted that in this embodiment, a fan power cable is provided on one side of the cabinet door 300 to electrically connect the multiple fan frequency conversion buttons 600.

[0057] Specifically, refer to Figure 1 and Figure 2In the embodiment of the present invention, a plurality of partition structures 111 are provided within the container 110. The partition structures 111 are used to divide the container 110 into a plurality of chambers 112. The plurality of chambers 112 are arranged in a vertical direction along the container 110, and each chamber 112 can be used to house a machine 200. Each row of induced blowers 410 is provided in conjunction with each chamber 112. With the above design, each row of induced blowers 410 is provided in conjunction with each chamber 112, and the cooling wind force and direction can be adjusted according to the specific needs of each chamber 112, achieving a customized cooling effect. Each chamber 112 can be operated and maintained independently, making the system more flexible and scalable.

[0058] It is understandable that, referring to Figure 1 and Figure 2 In the embodiment of the present invention, the partition structure 111 cooperates with the inner wall of the cavity 110 to form an air channel 113, and the air channel 113 is connected to the air outlet of the induced fan 410. Through the above arrangement, the cold air is introduced into the air channel 113 through the air supply mechanism 400, and heat is exchanged with the machine 200 through the side wall of the air channel 113. It can be understood that two air flows are accelerated by the induced fan 410. One air flow is the cold air flowing into the server or other machine 200. This part of the cold air directly contacts the internal heat dissipation components of the server or other machine 200 for heat exchange and cooling. The other air flow is the cold air flowing into the air channel 113. This part of the cold air contacts the surface of the server or other machine 200 for heat exchange, achieving the effect of cooling the server or other machine 200. The above structure increases the contact area between the cold air and the surface of the server or other machine 200, and further achieves the effect of enhancing heat exchange.

[0059] Specifically, in the embodiment of the present invention, the partition structure 111 includes two partitions disposed one above the other, which are connected to the inner wall of the cavity 110 to form an air passage 113. Of course, in some embodiments, the side between the two partitions facing the cabinet door 300 can also be blocked by a baffle, which is detachably connected to the two partitions and can be removed or installed as needed, which is not limited here.

[0060] It is understandable that, referring to Figure 1 、 Figure 2 and Figure 4In an embodiment of the present invention, the cabinet further includes a filter structure 700. The filter structure 700 is disposed on the air inlet side of the cabinet door 300 and is connected to the cabinet door 300. The air supply mechanism 400 is located on the air outlet side of the cabinet door 300. The filter structure 700 is used to filter the gas flowing from the air outlet end of the air supply mechanism 400 to the volume chamber 110. Through the above structure, the cold air is filtered by the filter structure 700 before entering the volume chamber 110. After filtering, the cold air is transported by the air supply mechanism 400 to the volume chamber 110 and the machines 200 such as servers for heat exchange and cooling. The use of the filter structure 700 can effectively filter the air entering the air supply mechanism 400, remove impurities such as dust and particulate matter, improve the quality of the air inhaled by the air supply mechanism 400, further improve the cleanliness of the cold air, and improve the reliability of the safe and stable operation of the machines 200 such as servers.

[0061] Specifically, in the embodiment of the present invention, the filter structure 700 is detachably connected to the cabinet door 300. This detachable connection makes the filter structure 700 easier to disassemble and clean, reducing the time and labor costs during maintenance. It should be noted that in the embodiment of the present invention, the filter structure 700 can be detachably mounted to the cabinet door 300 by means of screwing, snapping, or the like.

[0062] Specifically, refer to Figure 1 、 Figure 2 and Figure 4 In this embodiment of the utility model, the filter structure 700 is an air filter. As a form of the filter structure 700, the air filter is easy to clean and replace, making the maintenance process more convenient. It should be noted that in this embodiment, a mezzanine space can be provided on the air inlet side of the cabinet door 300, and the air filter can be removably inserted into the mezzanine space.

[0063] Of course, in some embodiments, the filtering structure 700 may also be an electrostatic precipitator that utilizes the electric field principle to absorb particles and pollutants in the air, and is suitable for removing fine particles and smoke, which is not limited here.

[0064] It is understandable that, referring to Figures 1 to 5 In an embodiment of the present utility model, the computer room includes the above-mentioned cabinets and a hot channel area 800, and the hot channel area 800 is provided with a closed door 810 for closing or opening the hot channel area 800; wherein, a cabinet is provided on at least one side of the hot channel area 800, and the cavity 110 of the cabinet is provided with an air outlet, which is connected to the hot channel area 800.

[0065] It should be noted that in this embodiment, there are multiple cabinets, and multiple cabinets are provided on opposite sides of the hot channel area 800 to make rational use of space; the above-mentioned air outlet can be understood as an air outlet hole or an air outlet channel, and the cavity 110 can be connected to the hot channel area 800 through the arrangement of one or multiple air outlet holes, so that hot air flows into the hot channel area 800.

[0066] It can be understood that the cold air in the cold channel of the computer room first passes through the air filter to remove dust before entering the cabinet. Figure 1 and Figure 2 Arrow A in the middle can be understood as the direction of cold air flow. The induction fan 410 provides power to speed up the cold air speed. The cold air flows into the air channel 113 and the inside of the server and other machines 200, increasing the contact area between the cold air and the server. After the cold air and the server and other machines 200 fully exchange heat, the hot air is formed and flows from the air inlet side to the hot channel area 800 and then discharged from the machine room. You can refer to Figure 5 , arrow B can be understood as the direction of hot air flow.

[0067] It should be noted that, in this embodiment, the power provided by the induced fan 410 can not only accelerate the cold air, but also enhance the heat exchange efficiency between the server and other machines 200 and the cold air after the increase in the cold air speed. The rapid circulation of air can accelerate the flow of heat, solve the problem of heat accumulation around the server and other machines 200, and can also quickly discharge the hot air in the hot channel area 800 out of the computer room, so that the airflow organization in the cabinet has better fluidity.

[0068] Finally, it should be noted that the above embodiments are intended only to illustrate the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art will appreciate that various combinations, modifications, or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and are intended to be covered by the scope of protection of the present invention.
