DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0041] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0042] The existing double-sided cooling equipment inside the communication room, such as optical transport network (ONT) equipment, has many brands and models, and various styles, resulting in different depths of such equipment in the communication room, and complicated styles of air inlet and outlet. There are two cooling methods for such equipment: single-sided cooling and double-sided cooling. Among them, the double-sided cooling equipment is to install two single-sided cooling equipment back to back and combine them into one. Among them, double-sided refers to the front and rear areas inside the network rack or cabinet along the depth direction.

[0043] When the equipment is cooled on one side, in order to ensure that the internal boards of the equipment can absorb cold air flow to achieve the heat dissipation effect, the equipment is generally installed side by side with the network rack, and the front of the equipment is flush with the front of the network rack to ensure that the cabinets in the same row can absorb cold air flow from the same side. However, because the depth of such equipment is generally much smaller than the depth of the network rack in the same row, it is easy to reduce the utilization rate of the plane resources in the room. Some manufacturers design this type of single-row shallow depth equipment to be installed back-to-back as an integrated form of double-sided cooling, and then install it in the same row with the network rack. This ensures that the depth of the double-sided cooling equipment is close to that of the network rack, and improves the utilization type of plane resources in the communication room. However, the network rack generally absorbs cold air from the front and discharges hot air to the back. This type of integrated double-sided cooling equipment is easy to absorb the hot air discharged from the back of the same row of network racks, which is not conducive to the heat dissipation of its internal boards.

[0044] However, the current cooling solution in the communication room mainly uses room-level air conditioning for diffuse air supply to fill the entire communication room with cold air flow, thereby ensuring that each single-sided and double-sided cooling equipment can operate under reasonable temperature conditions. However, it cannot solve the problem of air flow disorder between various types of equipment in the communication room, and it is also easy to cause mixing of cold and hot air flows in the communication room, waste of cold air flow, etc., which is not conducive to energy saving inside the communication room.

[0045] In view of this, a combination cabinet is provided in an embodiment of the present application. Figure 1 This is a schematic diagram of the structure of a combined cabinet according to an embodiment of the present application. Figure 2 This is a top view of a cabinet according to an embodiment of the present application.

The combined cabinet also includes a hood 300, the equipment cabinet 110 includes a third surface 01c, the third surface 01c is provided with a first air outlet 02a, the hood 300 and the cabinet 100 and the air duct cabinet 200 are arranged to form a return air channel 30 extending along the second direction, and the return air channel 30 is connected to the first air outlet 02a.

[0046] Figure 4 This is a schematic diagram of the structure of an equipment cabinet of an embodiment of the present application. Please refer to Figures 2 to 4 , the first direction D1 is the depth direction of the equipment cabinet 110. The first enclosure 120 is a metal frame independently attached to the first surface 01a of the equipment cabinet 110. Along the first direction, one side of the metal frame can be fixed to the equipment with the door panel 111 and hinge removed, for example, fixedly connected to the column 112 of the equipment cabinet 110, and the other side of the metal frame is closed. The door panel 111, hinge removed from the equipment cabinet 110 or the door panel 111, hinge designed separately can be installed on the other side of the metal frame to prevent the airflow from directly diffusing into the communication room, so that the airflow entering the first air duct 04 can flow along the second direction D2 and can enter the equipment cabinet 110 through the first air inlet 03a of the first surface 01a to cool the equipment cabinet 110.

[0047] Continue to refer to Figures 2 to 4, the second enclosure 130 is a metal frame independently attached to the second surface 01b of the equipment cabinet 110. Along the first direction, one side of the metal frame can be fixed to the equipment with the door panel 111 and hinge removed, for example, fixedly connected to the column 112 of the equipment cabinet 110, and the other side of the metal frame is closed. The door panel 111 and hinge removed from the equipment cabinet 110 or the door panel 111 and hinge designed separately can be installed on the other side of the metal frame to prevent the airflow from directly diffusing into the communication room, so that the airflow entering the second air duct 07 can flow along the second direction and can enter the equipment cabinet 110 through the second air inlet of the second surface 01b to cool the equipment cabinet 110.

[0048] It should be noted that the equipment cabinet 110 in the present application is a double-sided cooling device, which can be an independent device or a combination of two single-sided cooling devices installed back to back. To avoid redundant description, the following content takes the double-sided cooling equipment cabinet 110 formed by assembling two single-sided air inlet devices installed back to back and with a small depth as an example for relevant description.

[0049] The cabinet 100 may include one, two or more equipment cabinets 110, which are specifically configured according to actual conditions. Preferably, each cabinet 100 includes 2-4 equipment cabinets 110 arranged along the second direction.

[0050] It is understandable that the position of the first air inlet 03a of the equipment cabinet 110 on the first surface 01a is not limited in the present application, and the position of the first air inlet 03a is set according to the actual needs of the equipment cabinet 110. Figure 4 As shown, the first air inlet 03 a is disposed in the middle of the first surface 01 a of the equipment cabinet 110 . Figure 5 This is a schematic diagram of the structure of an equipment cabinet in another embodiment of the present application. Figure 5 As shown, the first air inlet 03 a is disposed at the lower portion of the first surface 01 a of the equipment cabinet 110 . Figure 6 This is a structural diagram of an equipment cabinet in another embodiment of the present application. Figure 6 As shown, the upper, middle and lower parts of the first surface 01a of the equipment cabinet 110 are each provided with a first air inlet 03a.

[0051] Similarly, the present application does not limit the position of the second air inlet of the equipment cabinet 110 on the second surface 01b. The second air inlet can be located at the upper, middle or lower part of the second surface 01b, depending on the actual needs of the equipment cabinet 110.

[0052] Among them, the first partition 140 can be moved along the height direction D3 of the cabinet 100, and the specific position of the first partition 140 is set according to the position of the first air inlet 03a on the first surface 01a, so that the first air inlet 03a is only connected to the first area 05 of the first air duct 04, so that the cold air flow is directed into the first area 05, and then enters the interior of the equipment cabinet 110 through the first air inlet 03a, avoiding the cold air flow from flowing in other areas of the first air duct 04, thereby improving the utilization rate of the cold air flow. Similarly, the second partition 150 can be moved along the height direction D3 of the cabinet 100, and the specific position of the second partition 150 is set according to the position of the second air inlet on the second surface 01b, so that the second air inlet is only connected to the third area 08 of the second air duct 07, so that the cold air flow is directed into the third area 08, and then enters the interior of the equipment cabinet 110 through the second air inlet, avoiding the cold air flow from flowing in other areas of the second air duct 07, thereby improving the utilization rate of the cold air flow.

[0053] like Figure 5 As shown, when the first air inlet 03a of the equipment cabinet 110 is located at the lower part of the first surface 01a, correspondingly, along the height direction of the equipment cabinet 110, as shown in FIG. Figure 3 As shown, the first partition 140 can be arranged at the lower part of the first enclosure 120. It can be understood that the position of the first partition 140 is higher than the position of the first air inlet 03a, so that the first area 05 corresponds to the first air inlet 03a at the lower part of the equipment cabinet 110, and the specific position is adjusted according to the position of the first air inlet 03a. Figure 6 This is a structural diagram of an equipment cabinet in another embodiment of the present application. Figure 6 As shown, when the first air inlet 03a is provided at the upper, middle and lower parts of the first surface 01a of the equipment cabinet 110, the first partition plate 140 can be provided at the upper part of the first frame 120, specifically, it needs to be higher than the first air inlet 03a at the upper part of the first surface 01a. Figure 7 FIG. 1 is a schematic diagram of a cabinet having a hood on the top in another embodiment of the present application. Figure 7 As shown, the first partition plate 140 moves to the upper part of the first air duct 04 according to the position of the first air inlet 03a.

[0054] Similarly, the position of the second partition 150 can be higher than the position of the second air inlet, so that the third area 08 corresponds to the second air inlet on the equipment cabinet 110. For the description of the specific position of the second partition 150, please refer to the description of the first partition 140 above, which will not be repeated here.

[0055] It should be noted that, along the height direction of the air duct cabinet 200, the first area 05 in the first air duct 04 may be located below the second area 06, and the first area 05 may also be located below the second area 06, which is specifically divided according to the position of the first air inlet 03a. Figure 4As shown, when the first air inlet 03a is disposed in the middle of the first surface 01a of the equipment cabinet 110, Figure 8 This is a schematic diagram of the structure of a cabinet with a hood on the top of another embodiment of the present application, referring to Figure 8 The first partition plate 140 is disposed at the lower part of the first air duct 04 , and the first area 05 is located above the second area 06 . The second partition plate 150 is disposed at the lower part of the second air duct 07 , and the third area 08 is located above the fourth area 09 .

[0056] In some optional embodiments, the first surface 01a of the equipment cabinet 110 is further provided with a second air outlet 02b, and the second area 06 is connected to the second air outlet 02b. The second surface 01b is provided with a third air outlet, and the fourth area 09 is connected to the third air outlet. Figure 4 As shown, the second air outlet 02b may be located at the lower portion of the first surface 01a. Similarly, the third air outlet may be located at the lower portion of the second surface 01b.

[0057] Continue to refer to Figure 8 The first area 05 is provided with a third partition 160 that can move along the height direction D3 of the cabinet 100. The third partition 160 is used to separate the first area 05 into a first sub-area 05a and a second sub-area 05b. The first air inlet 03a is only connected to the first sub-area 05a. The cabinet 100 of the above structure is provided at the middle of the first surface 01a of the equipment cabinet 110 corresponding to the first air inlet 03a, which can prevent the cold air flow from flowing into the second sub-area 05b, thereby improving the utilization rate of the cold air flow.

[0058] Similarly, a fourth partition 170 is provided in the third area 08 and can move along the height direction of the cabinet 100. The fourth partition 170 is used to separate the third area 08 into a third sub-area 08a and a fourth sub-area 08b, and the second air inlet is only connected to the third sub-area 08a. The cabinet 100 of the above structure corresponds to the second air inlet being arranged in the middle of the second surface 01b of the equipment cabinet 110, which can prevent the cold air flow from flowing into the fourth sub-area 08b, thereby improving the utilization rate of the cold air flow.

[0059] When the first air duct 04 is provided with a first partition 140 and a third partition 160, and the second air duct 07 is provided with a second partition 150 and a fourth partition 170, the positions of the first partition 140, the third partition 160, the second partition 150 and the fourth partition 170 can be adjusted to adapt to the equipment cabinet 110 with different air inlet and air outlet structures. For example, when the upper part, the middle part and the lower part of the first surface 01a of the equipment cabinet 110 are provided with a first air inlet 03a, the first partition 140 and the third partition 160 can be moved upward to a position higher than the first air inlet 03a on the upper part of the first surface 01a of the equipment cabinet 110, and the second partition 150 and the fourth partition 170 can be moved upward to a position higher than the second air inlet on the upper part of the second surface 01b of the equipment cabinet 110. Fig. 9 1 is a schematic diagram of the structure of a cabinet according to an embodiment of the present application. In order to clearly see the internal structure of the cabinet 100, the door panel on the side of the first enclosure 120 away from the equipment cabinet 110 is removed from the figure. Fig. 9 As shown, the positions of the first partition plate 140 , the third partition plate 160 , the second partition plate 150 and the fourth partition plate 170 are all moved to the upper part of the cabinet 100 .

[0060] The first partition 140 can be detachably connected to the first enclosure 120, or the two can be slidably connected, as long as the first partition 140 can be moved along the height direction of the cabinet 100. For example, the first partition 140 is detachably connected to the frame of the first enclosure 120 by bolts. The configuration of the third partition 160, the second partition 150 and the fourth partition 170 is referred to the first partition 140, and will not be described in detail.

[0061] Continue to refer to Figure 1 The function of the air duct cabinet 200 is to change the flow direction of the airflow entering the air duct cabinet 200 so that the airflow flows into the preset area.

The first baffle plate 231 is located at the bottom of the first air guide plate 232 and is vertically connected to the first air guide plate 232. The first baffle plate 231 is flush with the first partition 140; the second baffle plate 241 is located at the bottom of the second air guide plate 242 and is vertically connected to the second air guide plate 242. The second baffle plate 241 is flush with the second partition 150. When the first plate body 230 and the second plate body 240 are separated, the first air guide plate 232, the first baffle plate 231, the second air guide plate 242 and the second baffle plate 241 are arranged to form a guide air duct A extending along the second direction. Along the first direction, the maximum size of the guide air duct A is larger than the size of the equipment cabinet 110, so that the external cold air flow can pass through the guide air duct A in the direction indicated by the arrow B in the figure, and then flow into the first area 05 and the third area 08 in a directed manner.

[0070] In some optional embodiments, along the first direction, the size of the first plate body 230 and the second plate body 240 are both 1 / 2 of the size of the equipment cabinet 110 to better match the size of the equipment cabinet 110 .
