Description

Technical Field

[0001] The utility model relates to the field of heat dissipation in a computer room, in particular to an IDC cabinet heat dissipation structure and an air conditioning system. Background Art

[0002] With the development of the Internet, IDC (Internet Data Center) has become an indispensable and important part of the Internet industry.

[0003] With the rapid progress of information application technology, the development speed of IDC is getting faster and faster. In traditional IDC computer rooms, there is a discrepancy between early planning and later business expansion. The update of highly integrated servers and high-power data storage devices in the cabinets has caused a significant increase in heat dissipation per unit area, and the requirements for computer room environment are becoming increasingly stringent, and the energy consumption of air conditioning systems has increased significantly. According to estimates, the energy consumption of air conditioning equipment in IDC computer rooms accounts for about 45% of the total energy consumption of computer rooms. The airflow organization design of the air conditioning system is one of the keys affecting the energy consumption of the air conditioning system in IDC computer rooms. By reasonably optimizing the airflow organization in the cabinet, the local temperature hotspots in the cabinet can be reduced, the cooling efficiency of the air conditioning system can be improved, the power consumption can be reduced, and the safe and reliable operation of the equipment can be guaranteed.

[0004] In the existing technology, most of the solutions for IDC air conditioning energy saving can be mainly divided into the following categories:

[0005] 1. Lower-cost cooling sources, including natural low-temperature water such as lake water or sea water, or more energy-efficient air conditioning equipment. However, the former has restrictions on the location of IDCs, while the latter faces the bottleneck of air conditioning technology development and has insufficient room for improvement.

[0006] 2. Stronger natural heat dissipation capabilities, including providing lower ambient temperature or stronger heat radiation capabilities. However, the former also restricts the site selection of IDCs, while the latter places extremely high demands on material selection and structural design.

[0007] Therefore, how to provide a low-cost IDC air conditioning system energy-saving solution is a technical problem that those skilled in the art hope to solve. Utility Model Content

[0037] An IDC cabinet heat dissipation structure, such as Figure 1 As shown, including:

[0038] The main air inlet 1 is arranged on the first side of the cabinet, with the bottom being the air inlet 1-1, the top being closed, and the side being provided with a plurality of first openings communicating with the cabinet equipment cavity 2;

[0039] The main air outlet 3 is arranged on the second side of the cabinet, with a closed bottom, an air outlet 3-1 at the top, and a plurality of second openings 3-2 communicating with the cabinet equipment cavity 2 on the side, wherein the first side and the second side are two opposite sides of the cabinet;

[0040] The injection valve 4 is arranged at the bottom of the main air outlet 3, and the direction of the injection port is parallel to the axis of the main air outlet 3. It is used to reduce the air pressure in the main air outlet 3 to drive the gas in the main air inlet 1 into the main air outlet 3 through the equipment cavity 2.

[0041] By setting up the main air inlet 1 and the main air outlet 3, assuming the equipment cavity 2 therein, and combining with the high-pressure airflow provided by the injection valve 4, the ejector principle can be formed, thereby accelerating the low-temperature gas in the main air inlet 1 to pass through the equipment cavity 2 and improving the heat dissipation effect.

[0042] In some embodiments, Figure 1 As shown, the main air outlet 3 is bent toward the equipment cavity 2, and the projection of the air outlet 3-1 on the horizontal plane is completely within the projection area of ​​the equipment cavity 2 on the horizontal plane. The main air outlet 3 is bent toward the equipment cavity 2, so that the air outlet 3-1 is located at the top of the equipment cavity 2. On the one hand, it is convenient to connect the air conditioner host 6, avoid interference with the equipment operation due to the connection of the air conditioner host 6, and improve the utilization rate of the space in the IDC room. On the other hand, it can also form a gas temporary storage cavity, thereby improving the heat exchange efficiency of the gas here and making the temperature of the gas more uniform.

[0043] In some embodiments, the main air inlet duct 1 further includes one or more detachable first plug plates, which are used to block the first opening when loaded. Correspondingly, the main air outlet duct 3 further includes one or more detachable second plug plates, which are used to block the second opening 3-2 when loaded. The first opening and the second opening 3-2 are aligned to reduce flow resistance, thereby improving the ejection efficiency.

[0044] In some embodiments, the direction of the injection port of the injection valve 4 coincides with the axis of the main air outlet 3. Of course, in other embodiments, the axis of the injection port of the injection valve 4 can be located on the inner side of the axis of the main air outlet 3, wherein the inner side is the side close to the equipment cavity 2.

[0045] In this embodiment, the side of the main air outlet 3 provided with the second opening 3-2 is divided into a plurality of side panels 3-3 by the second opening 3-2. Figure 2 As shown, each side panel 3-3 is arranged gradually closer to the equipment cavity 2 from top to bottom. By adjusting the inclination angle, the flow rate of each equipment cavity 2 can be made uniform, and the utilization rate of the low-temperature gas is improved. In this embodiment, the first opening and the second opening 3-2 are still aligned. Alignment specifically refers to that the projection line segments of the first opening and the second opening 3-2 in the numerical direction coincide.

[0046] In addition, the inclination angle of the side plate 3-3 can be set to be adjustable, and the inclination angle is specifically the angle with the numerical direction, so that it can be adjusted according to the actual situation to make the flow rate uniform and have a better injection effect. Of course, in some other embodiments, it can also be directly set to a fixed value, so that the structure is more stable. Specifically, the inclination angle can be set to:

[0047]

[0048] Among them: α is the inclination angle, A and B are coefficients, S is the area of ​​the horizontal section of the main air outlet 3 at the top of the side plate 3-3, h is the height of the second opening 3-2, and P is the outlet pressure of the injection valve 4. And the inclination angle should be at least greater than 2 degrees.

[0049] It has been verified through experiments that under the inclined design, the flow rate can be increased by 50% at the same outlet pressure of the injection valve 4 .

[0050] In addition, based on the above heat dissipation structure, an IDC air conditioning system is designed, such as Figure 3 As shown, it includes an air-conditioning host 6 and multiple cabinets, the cabinets include the heat dissipation structure as mentioned above, the outlet of the air-conditioning host 6 is connected to the air inlet 1-1 of each heat dissipation structure, and the inlet is connected to the air outlet 3-1 of each heat dissipation structure, and a regulating valve for adjusting the flow is provided between the outlet of the air-conditioning host 6 and the air inlet 1-1 of each heat dissipation structure.

[0051] In the present application, a specific air duct is set inside the cabinet to receive the low-temperature gas provided by the air-conditioning host 6, and the heat dissipation holes on the cabinet are sealed and modified, so that an approximately closed air duct is formed between the server and the front door panel of the cabinet. After taking away the heat from the equipment, the hot air is discharged from the top of the cabinet back to the air-conditioning host 6.

[0052] The design scheme of this application optimizes the airflow organization in the cabinet. The cold air is directly sent to the closed passage from the bottom of the cabinet. After the cold air takes away the heat of the equipment, the hot air leaves the cabinet and returns to the air conditioning unit. At this time, the environment in the computer room is at a higher temperature, which improves the cooling efficiency of the air conditioning system. The main principle of optimizing the airflow organization in the cabinet is to isolate the cold and hot air flows. The isolation of cold and hot air flows is to avoid the mixing of the cold air supply of the air conditioning system and the hot air generated by the equipment, thereby ensuring that the air inlet temperature entering the equipment is constant.
