Description

Technical Field

[0001] The utility model relates to the field of heat dissipation technology, and in particular to a drive cabinet and a wind wall system. Background Art

[0002] A drive cabinet is usually arranged in the wind wall system. The drive equipment arranged in the drive cabinet drives the fan of the wind wall system. The drive equipment generates a lot of heat during operation, which needs to be discharged in time, otherwise it will affect the normal operation of the drive equipment. The drive cabinet can be cooled by forced convection through the fan of the drive equipment itself, or it can introduce more air volume for cooling based on the fan of the wind wall system.

[0003] Since the fan of the wind wall system has a stronger wind pressure, in order to avoid interference between the wind field inside the drive cabinet and the wind field of the wind wall, the drive cabinet is usually arranged in the negative wind pressure area of ​​the wind wall system. In order to avoid increase in the thickness of the wind wall system, the drive cabinet is usually arranged horizontally in the wind wall system (that is, the side wall of the drive cabinet faces the air inlet side of the wind wall system). However, this will cause the side wall of the drive cabinet to be perpendicular to the air inlet direction of the wind field of the wind wall system, thereby occupying a larger air inlet area, resulting in increased air inlet resistance and increased fan power consumption. Utility Model Content

[0004] The embodiment of the utility model provides a drive cabinet and a wind wall system, which can solve the technical problems existing in the related technology. Specifically, the technical solution is as follows:

[0005] On the one hand, a drive cabinet is provided, which is applied to a wind wall system, and the drive cabinet includes a cabinet shell and a drive device; the cabinet shell has a connected air inlet and air outlet, and the air inlet and the air outlet are arranged side by side along a first direction, and the first direction intersects with the air inlet direction of the air inlet; the drive device is at least used to drive the first fan of the wind wall system, and the drive device is accommodated inside the cabinet shell.

[0006] The drive cabinet provided by the embodiment of the utility model has a drive device contained in the cabinet shell and located on the air flow path between the air inlet and the air outlet. The cold air entering from the air inlet of the cabinet shell exchanges heat with the drive device and cools it, and is finally discharged from the air outlet. Since the air inlet and air outlet of the cabinet shell are arranged side by side along the first direction, and the first direction intersects with the air inlet direction of the air inlet, the air after heat exchange can be discharged from the air outlet to the area adjacent to the air inlet rather than opposite to it. Such an arrangement is not only conducive to arranging the drive cabinet forward rather than horizontally in the wind wall system, but also conducive to arranging the drive cabinet across wind pressure zones in the wind wall system. For example, the drive cabinet penetrates the negative wind pressure zone of the wind wall system and partially extends into the positive wind pressure zone, and the air inlet and air outlet of the drive cabinet are both located in the negative wind pressure zone, and the windshield side wall of the drive cabinet is parallel to the air inlet direction. This can effectively avoid the following technical problems: the problem of reduced cooling air volume due to "short circuit" of the wind field, the problem of increased wind wall wind resistance due to the drive cabinet occupying the wind field inlet area, and the problem of the drive cabinet being close to the fan of the wind wall system, resulting in the need to shut down the wind wall system for maintenance of the drive cabinet. Moreover, the arrangement of the drive cabinet across wind pressure zones in the wind wall system can also reasonably utilize the space in some positive wind pressure zones of the wind wall system without increasing the thickness of the negative wind pressure zones of the wind wall system, thereby avoiding an increase in the overall thickness of the wind wall system.

[0007] In some possible implementations, the first direction is perpendicular to the air inlet direction of the air inlet.

[0008] In some possible implementations, the cabinet shell includes: a bracket portion and an air guide portion; the bracket portion accommodates the driving device and is provided with the air inlet; the air guide portion is bent and connected to the bracket portion, and the air guide portion is provided with the air outlet. Cold air first enters the interior of the bracket portion from the air inlet and performs heat exchange cooling on the driving device, and then the heat-exchanged air enters the air guide portion and is reversed through the bent structure, and is finally discharged from the air outlet.

[0009] In some possible implementations, the driving device includes: an air inlet end and an air outlet end that are connected and a second fan located at the air inlet end; the air inlet end of the driving device is connected to the air inlet of the cabinet shell, and the air outlet end of the driving device is connected to the air outlet of the cabinet shell.

[0010] In some possible implementations, the air inlet and air outlet of the driving device are arranged opposite to each other, and the air inlet of the driving device faces the air inlet of the cabinet shell. The driving device inhales cold air through the second fan, and the cold air is in turn inhaled through the air inlet of the cabinet shell from its air inlet end for heat exchange cooling, and then enters the air guide portion from the air outlet of the driving device and is discharged from the air outlet of the cabinet shell, thereby achieving forced convection cooling of the driving device based on the second fan.

[0011] In some possible implementations, a projection of the air outlet of the cabinet housing on the driving device is located between an air inlet end and an air outlet end of the driving device.

[0012] In some possible implementations, the air guide portion includes: a first air guide cavity, a second air guide cavity, and a third air guide cavity that are connected in sequence; the first air guide cavity is connected to the air outlet end of the driving device; the second air guide cavity is bent; the third air guide cavity extends along the direction from the air outlet end of the driving device to its air inlet end, and the extended end of the third air guide cavity serves as the air outlet of the cabinet shell.

[0013] In some possible implementations, the bracket portion includes: a first cavity, a second cavity, and a third cavity distributed in sequence along the direction of gravity, the second cavity accommodating the drive device; the drive cabinet also includes at least one wind shield, and the at least one wind shield is located at at least one of the following positions: the end of the first cavity on the same side as the air inlet, the end of the third cavity on the same side as the air inlet, the side of the second cavity facing the first cavity, and the side of the second cavity facing the third cavity.

[0014] In some possible implementations, the air outlet of the cabinet shell has a filter screen. The filter screen is designed to protect the inner cavity of the air guide portion to prevent foreign matter from entering the inner cavity.

[0015] In some possible implementations, the drive cabinet further includes a guide rail structure, which is connected to the inner wall of the cabinet shell and the outer wall of the drive device, and is used to guide the drive device to enter or exit the cabinet shell. The drive device is given a pluggable function, thereby facilitating maintenance of the drive device.

[0016] On the other hand, a wind wall system is provided, comprising: a drive cabinet as described above, a first fan and a wind wall shell; the first fan is located in the wind wall shell so that the air inlet side of the wind wall shell is connected to the air outlet side thereof; the drive cabinet is located inside the wind wall shell and the air inlet and air outlet of the drive cabinet both face the air inlet side of the wind wall shell; the drive device of the drive cabinet is electrically connected to the first fan to drive the first fan.

[0017] The wind wall system provided by the embodiment of the utility model is based on the use of the drive cabinet involved in the embodiment of the utility model, and has all the advantages of the drive cabinet. The drive cabinet performs wind field deflection of the cooling wind through the air guide part, which can realize that the air inlet and air outlet of the drive cabinet are located on the same side (for example, front air inlet and front air outlet). Therefore, the drive cabinet can be arranged alone in the negative wind pressure area, or it can be arranged in the negative wind pressure area and the positive wind pressure area at the same time, so that the drive cabinet can be flexibly arranged in the wind wall system without being affected by the wind pressure area of ​​the installation position. On the premise of ensuring the heat exchange effect of the drive cabinet and the wind wall system, the overall thickness of the wind wall system will not be increased.

[0018] In some possible implementations, the wind wall system also includes a partition located inside the wind wall shell, the partition is used to separate the air inlet side and the air outlet side of the wind wall shell, and the first fan is arranged through the partition; the drive cabinet is arranged through the partition, or is located between the partition and the air inlet side of the wind wall shell.

[0042] In the description of the embodiments of the present invention, it should be understood that the terms "inside", "outside", "up", "down", "front", "back", "vertical", "horizontal", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. When the product is placed in different postures, the direction may change, and therefore it should not be understood as a limitation on the embodiments of the present invention.

[0043] A drive cabinet is usually arranged in the wind wall system to drive the fan of the wind wall system. As a centralized storage and operation place for drive equipment, the drive cabinet is expected to discharge the heat generated by the drive equipment in time, otherwise the temperature inside the drive cabinet will continue to rise. The drive equipment is sensitive to the working temperature, and too high operating temperature will reduce the efficiency of the electronic devices contained therein, and even cause burns and other hazards. It can be seen that timely and effective heat dissipation of the drive cabinet is very necessary.

[0044] The drive cabinet can achieve heat dissipation through forced convection cooling of the fan built into the drive device. However, when the drive cabinet is used in a wind wall system, since the fan built into the wind wall system has a stronger wind pressure, considering the interference between the wind field inside the drive cabinet and the wind field of the wind wall, it is necessary to avoid the drive cabinet being in different wind pressure zones, which may cause the wind field to "short-circuit", thereby reducing the cooling air volume of the drive equipment. Therefore, the drive cabinet is usually arranged in the same wind pressure zone of the wind wall system, for example, only in the negative wind pressure zone.

[0045] When the drive cabinet is arranged in the negative wind pressure area of ​​the wind wall system, if the air inlet end of the drive device itself is faced to the air inlet end of the wind wall system, then the thickness of the negative wind pressure area of ​​the wind wall system must be greater than the thickness of the drive device (wherein, the thickness of the wind wall system and the drive device refers to the dimension along the direction from the air inlet end of the drive device to its air outlet end), thereby increasing the total thickness of the wind wall system.

[0046] In order to avoid increasing the thickness of the wind wall system, the drive cabinet is usually arranged horizontally in the wind wall system (that is, the windproof side wall of the drive cabinet faces the air inlet end of the wind wall system, and the air inlet end of the drive device is perpendicular to the air inlet end of the wind wall system). However, this will cause the side wall of the drive cabinet to be perpendicular to the wind field air inlet direction of the wind wall system, thereby occupying a larger air inlet area, resulting in increased air inlet resistance and increased fan power consumption, thereby reducing the overall efficiency of the wind wall system. In addition, the drive cabinet is arranged horizontally in the wind wall system, so that the drive cabinet and the fan of the wind wall system are relatively close, which makes the maintenance of the drive cabinet more inconvenient. For safety reasons, in order to prevent the fan from sucking in foreign objects during maintenance, the drive equipment and the wind wall system usually need to stop running, which is not suitable for application scenarios such as data centers that require long-term non-stop operation.

[0047] On the one hand, the embodiment of the utility model provides a drive cabinet 100, which is applied to a wind wall system, as shown in the attached Figure 1 As shown, the drive cabinet 100 includes a cabinet shell 1 and a drive device 2. The cabinet shell 1 has an air inlet 101 and an air outlet 102 that are connected to each other. The air inlet 101 and the air outlet 102 are arranged side by side along a first direction D1, and the first direction D1 intersects with the air inlet direction of the air inlet 101. The drive device 2 is at least used to drive the first fan 200 of the wind wall system, and the drive device 2 is accommodated inside the cabinet shell 1.

[0048] The drive cabinet 100 provided by the embodiment of the utility model has a drive device 2 accommodated inside the cabinet shell 1 and located on the wind path between the air inlet 101 and the air outlet 102. The cold air entering through the air inlet 101 of the cabinet shell 1 performs heat exchange cooling on the drive device 2 and is finally discharged from the air outlet 102. Since the air inlet 101 and the air outlet 102 of the cabinet shell 1 are arranged side by side along the first direction D1, and the first direction D1 intersects with the air inlet direction of the air inlet 101, the air after heat exchange can be discharged from the air outlet 102 to the area adjacent to the air inlet 101 instead of the opposite area. Such an arrangement is not only conducive to arranging the drive cabinet 100 forwardly rather than laterally in the wind wall system, but also conducive to arranging the drive cabinet 100 across the wind pressure zone in the wind wall system. For example, the drive cabinet 100 passes through the negative wind pressure zone 001 of the wind wall system and partially extends to The positive wind pressure zone 002, and the air inlet 101 and the air outlet 102 of the drive cabinet 100 are both located in the negative wind pressure zone 001, and the wind-shielding side wall of the drive cabinet 100 is parallel to the wind inlet direction, which can effectively avoid the following technical problems: the problem of reduced cooling air volume due to the "short circuit" of the wind field, the problem of increased wind resistance of the wind wall caused by the drive cabinet 100 occupying the wind field inlet area, and the problem that the drive cabinet 100 is close to the fan of the wind wall system, which requires the wind wall system to be shut down before the drive cabinet 100 can be maintained. Moreover, the cross-wind pressure zone arrangement of the drive cabinet 100 in the wind wall system can also reasonably utilize the space of part of the positive wind pressure zone 002 in the wind wall system, and will not increase the thickness of the negative wind pressure zone 001 of the wind wall system, thereby avoiding an increase in the overall thickness of the wind wall system.

[0049] The “positive arrangement of the drive cabinet 100” mentioned above in the embodiment of the utility model can be considered as the arrangement orientation of the drive cabinet 100 in the wind wall system makes the air inlet 101 of the cabinet shell 1 face the air inlet side of the wind wall system.

[0050] The “transverse arrangement of the drive cabinet” mentioned above in the embodiment of the utility model can be considered to mean that the arrangement orientation of the drive cabinet in the wind wall system makes the wind-shielding side wall of the cabinet shell 1 face the air inlet side of the wind wall system.

[0051] As mentioned above in the embodiment of the utility model, the first direction D1, that is, the side-by-side arrangement direction of the air inlet 101 and the air outlet 102 of the cabinet shell 1 intersects with the air inlet direction of the air inlet 101. Figure 1 As shown, the first direction D1 is perpendicular to the air inlet direction of the air inlet 101, thereby ensuring that the air inlet direction of the air inlet 101 is parallel to and opposite to the air outlet direction of the air outlet 102, that is, the angle between the air inlet direction of the air inlet 101 and the air outlet direction of the air outlet is 180°, which is conducive to realizing front airflow and front outlet of the air in the cabinet shell 1.

[0052] Based on the above technical concept of the embodiment of the utility model, it can be known that compared with the related art that usually makes the air inlet direction and the air outlet direction of the cabinet shell 1 vertically connected (the angle between the two is 0° and the inlet and outlet are opposite), the embodiment of the utility model can not only set the angle between the air inlet direction of the air inlet 101 and the air outlet direction of the air outlet to 180°, but also set the angle between the air inlet direction of the air inlet 101 and the air outlet direction of the air outlet 102 to be slightly less than 180°. For example, when the angle between the two is greater than or equal to 90°, the air after heat exchange can be discharged from the air outlet 102 to the adjacent side of the air inlet 101 instead of the opposite area.

[0053] In some examples, such as the attached Figure 1 -Attached Figure 3 As shown, the cabinet shell 1 includes: a bracket portion 11 and an air guide portion 12; the bracket portion 11 accommodates the driving device 2 and is provided with an air inlet 101; the air guide portion 12 is bent and connected to the bracket portion 11, and is provided with an air outlet 102.

[0054] By accommodating the driving device 2 in the bracket portion 11 and providing the bending structure in the air guide portion 12, it is ensured that the cold air first enters the interior of the bracket portion 11 from the air inlet 101 and performs heat exchange cooling on the driving device 2, and then the air after heat exchange enters the air guide portion 12 and is reversed through the bending structure, and finally discharged from the air outlet 102. Exemplarily, the air guide portion 12 may have a U-shaped bending structure so that the air entering the air guide portion 12 can achieve U-shaped reversal.

[0055] In some examples, such as the attached Figure 3 As shown, the driving device 2 includes: an air inlet end 21 and an air outlet end 22 which are connected and a second fan 23 located at the air inlet end 21; the air inlet end 21 of the driving device 2 is connected to the air inlet 101 of the cabinet shell 1, and the air outlet end 22 of the driving device 2 is connected to the air outlet 102 of the cabinet shell 1.

[0056] Based on the above arrangement of the driving device 2, when in use, the driving device 2 inhales cold air through the second fan 23, and the cold air in turn inhales the cold air through the air inlet of the cabinet shell 1 from its air inlet end 21 to heat exchange and cool it. The heat exchanged air enters the air guide part 12 through the air outlet end 22 of the driving device 2 and is discharged from the air outlet 102 of the cabinet shell 1. Thus, the forced convection cooling of the driving device 2 is achieved based on the second fan 23 (see Figure 3 and Figure 4 ). The “forced convection cooling” referred to herein refers to a solution in which cold air is forced to flow around the drive device 2 to achieve cooling.

[0057] One implementation scheme is as follows Figure 3As shown, the air inlet end 21 and the air outlet end 22 of the driving device 2 are arranged opposite to each other, and the air inlet end 21 of the driving device 2 faces the air inlet 101 of the cabinet shell 1, so that cold air flows through the air inlet 101 of the cabinet shell 1 and the air inlet end of the driving device 2 in a straight-through manner.

[0058] In the embodiment of the utility model, the plane where the air outlet 102 of the cabinet shell 1 is located may be flush with the plane where the air inlet 101 of the cabinet shell 1 is located in the first direction D1, or may not be flush with each other. In some examples, such as the attached Figure 3 As shown, the projection of the air outlet 102 of the cabinet housing 1 on the driving device 2 can be located between the air inlet end 21 and the air outlet end 22 of the driving device 2. In other words, the air outlet 102 of the cabinet housing 1 is arranged concavely relative to the air inlet 101 of the cabinet housing 1, so that there is a gap between the plane where the air outlet 102 of the cabinet housing 1 is located and the plane where the air inlet 101 of the cabinet housing 1 is located.

[0059] When the drive cabinet 100 is used in a wind wall system, the air inlet 101 and the air outlet 102 of the cabinet shell 1 can be arranged facing the air inlet side 301 of the wind wall system, so that the gap width between the air inlet 101 of the cabinet shell 1 and the air inlet side 301 of the wind wall system can be smaller than the gap width between the air outlet 102 of the cabinet shell 1 and the air inlet side 301 of the wind wall system. The "gap width" involved here refers to the dimension along the air flow direction.

[0060] Through the above arrangement, the air entering the drive device 2 through the air inlet 101 of the cabinet shell 1 is finally discharged to the gap between the air outlet 102 of the cabinet shell 1 and the air inlet side 301 of the wind wall system after heat exchange, which effectively avoids part of the air from flowing back to the air inlet 101 of the cabinet shell 1, which is beneficial to improving the heat dissipation effect of the drive cabinet 100. In addition, there is a gap between the plane where the air outlet 102 of the cabinet shell 1 is located and the plane where the air inlet 101 of the cabinet shell 1 is located, which also allows the air after heat exchange of the drive device 2 to be fully mixed with the cold air from the outside, and is sucked into the heat exchange path of the wind wall system under the action of the first fan 200 of the wind wall system, ensuring the heat exchange effect of the wind wall system.

[0061] In the embodiment of the utility model, the gap width between the air outlet 102 of the cabinet shell 1 and the plane where the air inlet 101 of the cabinet shell 1 is located, and the gap width between the air outlet 102 of the cabinet shell 1 and the air inlet side 301 of the wind wall system can be designed according to actual heat exchange requirements.

[0062] The following is an exemplary description of the structure and arrangement of the bracket portion 11 and the air guide portion 12 of the cabinet housing 1.

[0063] The air guide portion 12 has an air guide wall plate and an inner cavity formed by the air guide wall plate. The air guide wall plate of the air guide portion 12 is fixedly connected to the bracket portion 11. The inner cavity of the air guide portion 12 and the wall plate of the bracket portion 11 can cooperate to form an air guide cavity. Since the structure of the bracket portion 11 is usually fixed or universal, the structure and direction of the air guide portion 12 can be adaptively determined according to the structure of the air guide cavity.

[0064] The air after heat exchange with the drive device 2 is reversed by the air guide part 12 and guided to the air outlet 102. It can be seen that the air guide part 12 can have a bending structure to achieve the reversal of the air guide cavity, for example, to achieve the purpose of making the air inlet direction and the air outlet direction of the wind field in the drive cabinet 100 opposite, that is, reversely parallel.

[0065] On the basis that the air guide portion 12 has a bent structure, the structure of the air guide portion 12 can be designed into various types to ensure that the inlet end of the air guide portion 12 is connected to the outlet end 22 of the driving device 2, and the air outlet 102 arranged on the air guide portion 12 extends to be arranged side by side with the air inlet 101 in the first direction D1.

[0066] An exemplary structure of the air guide portion 12 is as follows: Figure 3 and Figure 4 As shown, the air guide part 12 includes: a first air guide cavity 121, a second air guide cavity 122 and a third air guide cavity 123 which are connected in sequence; the first air guide cavity 121 is connected to the air outlet end 22 of the driving device 2; the second air guide cavity 122 is bent; the third air guide cavity 123 extends along the direction from the air outlet end 22 of the driving device 2 to its air inlet end 21, and the extended end of the third air guide cavity 123 serves as the air outlet 102 of the cabinet shell 1.

[0067] For example, the first air guiding cavity 121 faces the air outlet 22 of the driving device 2, so that the heat exchange air discharged from the air outlet 22 of the driving device 2 enters the first air guiding cavity 121 of the air guiding portion 12 without obstruction and low resistance (or even without resistance).

[0068] If the position of the air inlet end 21 of the driving device 2 is defined as the front, and the position of the air outlet end 22 of the driving device 2 is defined as the rear, it can be understood that the first air guide cavity 121 is located at the rear of the bracket part 11. Although this will increase the size (i.e., thickness) of the driving cabinet 100 along the front-to-back direction, due to the position arrangement of the air outlet 102 of the cabinet shell 1, the driving cabinet 100 can be arranged across the wind pressure zone in the wind wall system, and the idle space in the positive wind pressure zone 002 can be reasonably utilized, thereby avoiding increasing the thickness of the wind wall system.

[0069] The structure of the first air guiding cavity 121 may be a regular geometric shape or an irregular geometric shape, for example, including but not limited to: a rectangular shape, an arc shape, etc.

[0070] Further integration Figure 5 The second air guiding cavity 122 is bent (for example, a folded line bending form or a curved bending form), which plays a role of transition and switching. For example, the second air guiding cavity 122 is a U-shaped bending structure.

[0071] The second air guiding cavity 122 may be formed by a part of the outer wall of the cabinet shell 1 and a corresponding air guiding wall plate of the air guiding portion 12. The wall plate of the air guiding portion 12 corresponding to the second air guiding cavity 122 may be a bent straight panel or a curved panel.

[0072] In some examples, the bend of the second air guiding cavity 122 may be designed as a smooth transition structure to reduce air outlet resistance and improve heat dissipation efficiency.

[0073] Further integration Figure 5 The third air guide cavity 123 is arranged side by side with the cabinet shell 1 along the first direction D1, and the third air guide cavity 123 extends from the air outlet end 22 of the driving device 2 to its air inlet end 21, so that the air outlet 102 of the cabinet shell 1 and its air inlet 101 are arranged adjacent to each other along the first direction D1, and further, the air outlet 102 of the cabinet shell 1 is closer to the air inlet end 21 of the driving device 2 relative to the air outlet end 22 of the driving device 2.

[0074] In the embodiment of the utility model, the third air guiding cavity 123 may be a linear cavity (eg, a rectangular cavity) to reduce the probability of collision between the air and the side wall of the third air guiding cavity 123 and ensure rapid air discharge.

[0075] The third air guide cavity 123 may be formed by the outer wall of the cabinet housing 1 and the corresponding air guide wall plate of the air guide portion 12, and the structure of the air guide wall plate corresponding to the third air guide cavity 123 may be designed according to the structure of the third air guide cavity 123. Figure 5 As shown, the third air guide cavity 123 is a rectangular cavity. Accordingly, the air guide wall plate corresponding to the third air guide cavity 123 can be a flat panel, and the air guide wall plate is used to provide three surfaces of the rectangular cavity, and the outer wall of the cabinet shell 1 provides another surface of the rectangular cavity.

[0076] The extended end of the third air guide cavity 123 serves as the air outlet 102 of the cabinet shell 1. In some examples, the area of ​​the extended end of the third air guide cavity 123 can be larger than the area of ​​the starting end of the third air guide cavity 123, thereby achieving the purpose of improving the air outlet efficiency.

[0077] Based on the above, it can be known that the drive cabinet 100 provided in the embodiment of the utility model has an air guiding function by providing an air guiding portion 12 with a bending structure, so that the drive cabinet 100 is placed across the wind pressure zone in the wind wall system, while ensuring that the drive device 2 has excellent cooling capacity under different loads. At the same time, the drive cabinet 100 is placed across the wind pressure zone in the wind wall system, which realizes the flexible installation of the drive cabinet 100 and the convenience of maintenance of the drive device 2. This is because, compared with the horizontal arrangement, the forward arrangement of the drive cabinet 100 makes it away from the wind wall system's own fan and the second fan 23 of the drive device 2 is in the air inlet side area of ​​the wind wall system, so that the drive cabinet 100 can be maintained without stopping the wind wall system, so as to adapt to application scenarios such as data centers that require long-term shutdown.

[0078] The bracket part 11 is used to install the drive device 2 and other related equipment. The bracket part 11 may include a frame part and at least one wall plate part connected to the frame part, and the two cooperate to form the inner cavity of the bracket part 11. Figure 6 and Figure 7 As shown, the bracket portion 11 includes: a first cavity 1101, a second cavity 1102 and a third cavity 1103 distributed in sequence along the direction of gravity, and the second cavity 1102 accommodates the drive device 2; the drive cabinet 100 also includes at least one wind shield 13, and the at least one wind shield 13 is located at at least one of the following positions: the end of the first cavity 1101 on the same side as the air inlet 101, the end of the third cavity 1103 on the same side as the air inlet 101, the side of the second cavity 1102 facing the first cavity 1101, and the side of the second cavity 1102 facing the third cavity 1103.

[0079] Among them, the gravity direction involved above is Figure 6 In the second direction D2 shown in FIG. 1 , the number of driving devices 2 accommodated in the second cavity 1102 is usually multiple. When there are multiple driving devices 2 , the multiple driving devices 2 can be stacked in sequence along the second direction D2 .

[0080] Exemplarily, the plurality of driving devices 2 may include at least a fan driving device, and a communication device and a power supply device (eg, an AC / DC device, a DC / AC device, etc.) matched with the fan driving device.

[0081] For example, Figure 7 In the example, one wind shield 13 is located at the end of the third cavity 1103 on the same side as the air inlet 101 , and the other wind shield 13 is located at the side of the second cavity 1102 facing the first cavity 1101 .

[0082] The wind shield 13 serves as a wind shield. For the wind shield 13 located at the end of the third cavity 1103 on the same side as the air inlet 101, when the drive cabinet 100 is applied to the wind wall system, since the wind shield 13 is located below the drive device 2, this can prevent the cold air sucked in by the first fan 200 of the wind wall system from entering the space below the drive device 2, thereby ensuring that as much cold air as possible sucked in by the first fan 200 of the wind wall system enters the interior of the drive device 2, and no "heat exchange flow field short circuit" occurs, thereby increasing the air volume applied to the drive device 2 and improving the heat exchange amount, which is particularly beneficial for improving the heat exchange effect under high load.

[0083] For another wind shield 13 located on the side of the second cavity 1102 facing the first cavity 1101, the wind shield 13 can be connected to the frame part of the bracket part 11. The wind shield 13 can also ensure that the cold air sucked in by the first fan 200 of the wind wall system enters the interior of the driving device 2 as much as possible, thereby achieving the purpose of increasing the heat exchange capacity of the driving device 2.

[0084] As mentioned above, the second cavity 1102 is used to accommodate the driving device 2, and the first cavity 1101 and the third cavity 1103 can be empty cavities, or they can accommodate other devices, such as other heating devices. For example, the first cavity 1101 can accommodate a heating device with lower heat generation, such as a circuit board, and the third cavity 1103 can be empty, so that the bottom of the driving device 2 is suspended in the air. On the basis of ensuring the heat dissipation effect, it can also prevent the bottom of the driving device 2 from contacting unexpected impurities such as water.

[0085] When the first cavity 1101 accommodates a heat generating device with relatively low heat generation, ventilation and cooling treatment can be performed on the heat generating device. Figure 5 As shown, one of the wall panels of the bracket portion 11 is located at the end of the first cavity 1101 on the same side as the air inlet end 21 of the driving device 2 and serves as a ventilation plate 14; another wall panel of the bracket portion 11 is located at the end of the first cavity 1101 away from the second cavity 1102 and serves as another ventilation plate 14; yet another wall panel of the bracket portion 11 is located at the end of the first cavity 1101 adjacent to the third air guide cavity 123 and serves as yet another ventilation plate 14; yet another wall panel of the bracket portion 11 is located at the end of the third cavity 1103 adjacent to the third air guide cavity 123 and serves as yet another ventilation plate 14.

[0086] The frame in the bracket part 11 plays a supporting role, and its wall plate plays a shielding or protective role. When the wall plate of the bracket part 11 plays the role of a windshield, the wall plate of the bracket part 11 itself is a closed plate, and there is no hollow or hole structure on it to prevent air from passing through. Of course, the wall plate of the bracket part 11 can also be used as a ventilation plate with ventilation function, and there is a hollow or hole structure on it to allow air to pass through.

[0087] In addition, it should be noted that the wall panel of the bracket part 11 located at the end of the second cavity 1102 adjacent to the third air guide cavity 123 can be a closed plate, and the closed plate and the two ventilation plates 14 on the same side can be an integrated plate structure. The bracket part 11 also has a closed plate wall panel located on the side away from the third air guide cavity 123 to ensure that air enters the driving device 2 smoothly and fully.

[0088] In some examples, such as the attached Figure 3 As shown, the air outlet 102 of the cabinet shell 1 has a filter 3. The filter 3 is designed to protect the inner cavity of the air guide part 12 to prevent foreign objects from entering the interior.

[0089] In combination with any of the drive cabinets 100 involved in the above-mentioned embodiments of the utility model, the second fan 23 draws cold air from the front of the cabinet shell 1 and enters the drive device 2 through the air inlet 101 to cool it. The air after heat exchange enters the air guide part 12 through the air outlet end 22 (the air outlet end 22 is also provided with a filter 3) at the rear of the drive device 2. Under the guiding effect of the air guide part 12, the air is filtered by the filter 3 at the air outlet 102 of the cabinet shell 1 and then discharged from the drive cabinet 100.

[0090] In some examples, such as the attached Figure 2 and attached Figure 6 As shown, the drive cabinet 100 involved in the embodiment of the utility model further includes a guide rail structure 4, which is connected to the inner wall of the cabinet shell 1 and the outer wall of the drive device 2, and is used to guide the drive device 2 to enter or exit the cabinet shell 1. For example, the guide rail structure 4 is connected to the inner wall of the bracket part 11 and the outer wall of the drive device 2.

[0091] The drive device 2 performs a pulling and pulling motion based on the guide rail structure 4, so that the drive device 2 enters or exits the cabinet 1, giving the drive device 2 a pluggable function, thereby facilitating maintenance of the drive device 2. When the drive device 2 exits the inner cavity of the bracket part 11 for maintenance, it is further away from the fan of the wind wall system, which is beneficial for performing safe and reliable maintenance operations without stopping the wind wall system.

[0092] The guide rail structure 4 may include a guide rail member and a track member that cooperate with each other, one of which is connected to the inner side wall of the bracket portion 11, and the other is connected to the outer side wall of the drive device 2. The guide rail structure 4 may also include only a track member, which is connected to the inner side wall of the bracket portion 11 and adapted to accommodate the side of the drive device 2.

[0093] In combination with the bracket part 11 involved above, a guide rail structure 4 may be provided at the second cavity 1102. Further, a guide rail structure 4 may be provided at a first side of the bracket part 11 adjacent to the third air guide cavity 123 and a second side opposite to the first side, respectively, and a side wall of the drive device 2 is connected to the guide rail structure 4. When there are multiple drive devices 2, the multiple drive devices 2 may be stacked in sequence along the second direction D2, and a set of guide rail structures 4 may be provided separately for each drive device 2.

[0094] On the other hand, the utility model embodiment provides a wind wall system, as shown in the attached Figure 8 and attached Fig. 9 As shown, the wind wall system includes: any one of the drive cabinets 100 mentioned above, a first fan 200 and a wind wall shell 300; the first fan 200 is located in the wind wall shell 300, so that the air inlet side 301 of the wind wall shell 300 is connected to its air outlet side 302; the drive cabinet 100 is located inside the wind wall shell 200 and the air inlet 101 and the air outlet 102 of the drive cabinet 100 are both facing the air inlet side 301 of the wind wall shell 300; the drive device 2 of the drive cabinet 100 is electrically connected to the first fan 200 to drive the first fan 200.

[0095] It should be noted that a negative wind pressure zone 001 is formed between the air inlet side 301 of the wind wall shell 300 and the air inlet side of the first fan 200, and a positive wind pressure zone 002 is formed between the air outlet side of the first fan 200 and the air outlet side 302 of the wind wall shell 300, wherein the drive cabinet 100 can be located in at least one of the negative wind pressure zone 001 and the positive wind pressure zone 002.

[0096] The wind wall system provided by the embodiment of the utility model is based on the use of the drive cabinet 100 involved in the embodiment of the utility model, and has all the advantages of the drive cabinet 100. The drive cabinet 100 performs wind field deflection of the cooling wind through the air guide 12, which can realize that the air inlet and air outlet of the drive cabinet 100 are located on the same side (for example, front air inlet and front air outlet). Therefore, the drive cabinet 100 can be arranged alone in the negative wind pressure zone 001, or it can be arranged in the negative wind pressure zone 001 and the positive wind pressure zone 002 at the same time, so that the drive cabinet 100 can be flexibly arranged in the wind wall system without being affected by the wind pressure zone of the installation position. On the premise of ensuring the heat exchange effect of the drive cabinet 100 and the wind wall system, the overall thickness of the wind wall system will not be increased.

[0097] The wind wall system provided in the embodiment of the utility model can meet the thermal management of heat-generating equipment such as the drive device 2 in the drive cabinet 100 in different scenarios. For example, the cooling requirements of the drive cabinet 100 are realized when the wind wall system is no-load, light-loaded and fully-loaded. The following is an explanation of each of the different scenarios.

[0098] In the case of high load or full load of the wind wall system, the heat generated by the drive cabinet 100 is relatively large, so a large amount of cold air is required. Figure 8 Or attach Fig. 9 As shown, the first fan 200 of the wind wall system is working. At this time, the cooling of the heat generating equipment such as the drive device 2 in the drive cabinet 100 not only depends on the air volume introduced by the second fan 23 equipped with the drive device 2 itself, but also depends on the larger amount of cold air introduced by the first fan 200 equipped with the wind wall system, and finally realizes the forced convection cooling of the drive device 2 in the drive cabinet 100. Under the suction action of the second fan 23 of the drive device 2, the cold air introduced by the second fan 23 and part of the cold air introduced by the first fan 200 are discharged in sequence through the air inlet side 301 of the wind wall housing 300 - the air inlet 101 of the cabinet housing 1 - the air inlet end 21 of the drive device 2 - the drive device 2 as a whole - the air outlet end 22 of the drive device 2 - the air outlet 102 of the cabinet housing 1, so as to realize the forced convection cooling of the drive device 2. It can be seen that in the high load or full load scenario of the wind wall system, the second fan 23 and the first fan 200 cooperate to provide a large cooling air volume, thereby meeting the cooling demand of the drive device 2 in the drive cabinet 100 in this scenario.

[0099] In the case of no-load or light-load scenarios of the wind wall system, the heat generated by the drive cabinet 100 is relatively small. Fig.10 As shown, the first fan 200 of the wind wall system does not work, and the cooling of the heat generating equipment such as the drive device 2 in the drive cabinet 100 depends on the second fan 23 equipped by the drive device 2 itself, so as to realize forced convection cooling. Since the air inlet 101 and the air outlet of the cabinet shell 1 of the drive cabinet 100 are arranged facing the air inlet side 301 of the wind wall shell 300, the cold air is discharged through the air inlet side 301 of the wind wall shell 300-the air inlet 101 of the cabinet shell 1-the air inlet end 21 of the drive device 2-the whole of the drive device 2-the air outlet end 22 of the drive device 2-the air outlet 102 of the cabinet shell 1 in sequence under the suction action of the second fan 23 of the drive device 2, thereby realizing forced convection cooling of the drive device 2 based on the second fan 23. It can be seen that in the scenario when the wind wall system is unloaded or lightly loaded, the heat generated by the drive device 2 itself is small, and the required amount of cold air is low. Based on its second fan 23, the cooling demand of the drive device 2 when it is in standby can be met.

[0100] As attached Figure 8 -Attached Fig.10 As shown, the wind wall system provided by the embodiment of the utility model also includes: a partition 400 located inside the wind wall shell 300, the partition 400 is used to separate the air inlet side 301 and the air outlet side 302 of the wind wall shell 300, and the first fan 200 is arranged through the partition 300; the drive cabinet 100 is arranged through the partition 400, or is located between the partition 400 and the air inlet side 301 of the wind wall shell 300.

[0101] Attached Figure 8 The example shows that the drive cabinet 100 is arranged to pass through the partition 400, that is, the drive cabinet 100 passes through the negative wind pressure area 001 and partially extends into the positive wind pressure area 002. For example, the air outlet 22 of the drive device 2 in the drive cabinet 100 is located in the positive wind pressure area 002, the first air guide cavity 121 of the air guide part 12 in the drive cabinet 100 can be located in the positive wind pressure area 002, and the third air guide cavity 123 is located in the negative wind pressure area 001.

[0102] For this implementation scheme, cold air enters the drive device 2 from the air inlet side 301 of the wind wall system, undergoes heat exchange, and is finally discharged from the air outlet 102 to the negative wind pressure zone 001 of the wind wall system, and then is sucked in by the first fan 200 of the wind wall system and undergoes further heat exchange, which can effectively avoid the "short circuit" phenomenon in the wind field. At the same time, the cross-wind pressure zone arrangement of the drive cabinet 100 in the wind wall system rationally utilizes the space of part of the positive wind pressure zone 002 in the wind wall system, and will not increase the thickness of the negative wind pressure zone 001 of the wind wall system, thereby avoiding an increase in the overall thickness of the wind wall system. At the same time, it also avoids the problem of occupying the wind wall system's air inlet area caused by the horizontal arrangement of the drive cabinet 100.

[0103] Attached Fig. 9 The example shows that the drive cabinet 100 is located between the partition 400 and the air inlet side 301 of the wind wall shell 300, the drive cabinet 100 is located in the negative wind pressure zone 001, and the partition 400 blocks the rear end back panel of the drive cabinet 100, that is, the drive cabinet 100 is suitable for the scenario where its rear end back panel is blocked.

[0104] For this implementation scheme, the cold air enters the driving device 2 from the air inlet side 301 of the wind wall system, undergoes heat exchange, and is discharged from the air outlet 102 to the negative wind pressure area 001 of the wind wall system, and then is sucked in by the first fan 200 of the wind wall system for further heat exchange.

[0105] In the related art, since the air outlet is usually located on the rear back panel of the drive cabinet, once the partition blocks the rear back panel of the drive cabinet, the air outlet is bound to be blocked. The embodiment of the utility model can solve the technical problems existing in the related art by arranging the air outlet 102 and the air inlet 101 in the drive cabinet 100 side by side along the first direction D1, so as to make it suitable for the scene where the rear back panel of the drive cabinet 100 is blocked.

[0106] The above description is only for the purpose of facilitating the technical solution of the present invention to be understood by those skilled in the art, and is not intended to limit the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
