Description

Technical Field

[0001] This invention belongs to the field of heat dissipation in communication equipment, and in particular relates to a hybrid airflow heat dissipation device and method for horizontally inserted equipment. Background Technology

[0002] In existing technologies, when the enclosure is placed in the rack, space is usually reserved at the rear end for the communication equipment inside the horizontal insertion frame to run cables. There is also reserved space between the front end of the enclosure and the inner wall of the rack, as well as between the top and bottom ends of the enclosure and other enclosures. Therefore, when hot air is discharged from the enclosure's exhaust vent, it will either be output towards the rack's exhaust vents or flow from the top and bottom ends of the enclosure and the gaps between the front and rear ends to the vicinity of the air inlet, where it will be re-inhaled, causing hot air recirculation. As the number of communication devices inside the horizontal insertion frame increases and their power consumption increases, the requirements for heat dissipation performance also become more stringent. Under the interference of hot air recirculation, the difference between the air inlet temperature of the horizontal insertion frame and the actual temperature outside the rack can even be as high as ten degrees Celsius. Existing diversion and blocking structures are often incomplete or occupy a large amount of internal rack space, resulting in poor heat dissipation performance or reduced overall rack utilization.

[0003] Therefore, overcoming the shortcomings of the existing technology is an urgent problem to be solved in this technical field. Summary of the Invention

[0057] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

They are only for the convenience of describing this invention and do not require that this invention must be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0059] In this invention, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0060] In this application, unless otherwise expressly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, the term "coupled" can refer to an electrical connection that enables signal transmission.

[0061] Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0062] Example 1:

[0063] Embodiment 1 of the present invention provides a hybrid airflow cooling device for horizontally inserted equipment, such as... Figure 1 As shown, it includes: a housing 1, multiple baffles 2, and a cabinet 3, wherein:

[0064] The cabinet 3 has at least two boxes 1 arranged vertically.

[0065] In this embodiment, the cabinet 3 is provided with multiple equipment layers, and each equipment layer is provided with a box 1. The box 1 is used to set up a horizontal insertion frame, and the horizontal insertion frame is used to set up multiple communication devices and to complete the wiring connection inside the cabinet 3. According to the height of the horizontal insertion frame itself, multiple communication devices can be placed accordingly. The more communication devices there are, the higher the power consumption is usually, and the higher the cooling requirement is also.

[0066] like Figure 1 and Figure 2 As shown, the first end face 13 of the box body 1 is provided with an opening as an air inlet 11, and the second end face 14 of the box body 1 is provided with an opening as an air outlet 12. The first end face 13 and the second end face 14 of the box body 1 are located on both sides of the box body 1, respectively.

[0067] In this embodiment, the horizontal insert frame is in the form of left and right air ducts, that is, a fan is provided on one side of the horizontal insert frame for air intake, and the opposite side is for air exhaust, such as... Figure 1 and Figure 2 As shown, the first end face 13 of the box 1 is located on the left side of the figure, and the second end face 14 of the box 1 is located on the right side of the figure. When the box 1 is in use, the front end face of the box 1 can be opened, and the horizontal insertion frame is inserted from the front of the box 1. After the horizontal insertion frame is inserted into the box 1, the front of the box 1 is closed; the air inlet side of the horizontal insertion frame faces the opening of the first end face 13 of the box 1, and the air outlet side of the horizontal insertion frame faces the opening of the second end face 14 of the box 1. The air inlet 11 draws in the cold air from outside the cabinet 3. The cold air enters the interior of the horizontal insertion frame and exchanges heat with the various communication devices. Then the hot air is discharged from the air outlet 12.

[0068] It should be noted that the front of rack 3 usually has a rack door, and an air intake vent is located on the left side of the rack door near the first end face 13 of the enclosure 1. Figure 1 and Figure 2 As shown, the arrow indicates the direction of airflow transmission. The cold airflow enters through the air inlet hole of the cabinet door, turns right, enters the horizontal insertion frame through the air inlet 11, and exits through the air outlet 12. Since the air outlet 12 is located on the second end face 14 of the box body 1, the exhaust vent on the cabinet 3 should also be located on one side of the second end face 14. The exhaust vent can be located on the front, top, or back of the cabinet 3. Depending on the location of the exhaust vent, the direction of hot airflow discharge is guided accordingly.

[0069] It is important to note that Figure 1 and Figure 2 In the above, it is assumed that the exhaust vent of cabinet 3 is located on the front of cabinet 3, therefore Figure 1 and Figure 2 The hot airflow is output from the front of the cabinet 3, but in actual design, the exhaust vent can also be located on the top or back of the cabinet 3, and the corresponding hot airflow flows upward or backward after being output from the air outlet 12.

[0070] Similarly, in order to block the hot airflow from the top of the box 1, a baffle 2 can also be provided on the upper edge of the first end face 13, which is also perpendicular to the first end face 13.

[0071] like Figure 2 As shown, the baffle 2 is provided at the first preset position of the first end face 13 of the box body 1 and the second preset position of the front end face 15 of the box body 1. The baffle 2 abuts against the inner wall of the corresponding cabinet 3 or the adjacent box body 1. The baffle 2 is used to isolate the airflow of the air inlet 11 and the airflow of the air outlet 12.

[0072] In this embodiment, the plurality of baffles 2 refers to at least four baffles 2.

[0073] It should be noted that in this embodiment, the front face 15 refers to the end face of the box 1 facing the cabinet door opening when the box 1 is installed in the cabinet 3. Similarly, the rear face refers to the end face of the box 1 facing away from the cabinet door opening. In this embodiment, the descriptions of the orientation of the box 1 mentioned below are all based on the premise that the box 1 is installed in the cabinet 3.

[0074] When hot air is discharged from the air outlet 12, without obstruction, and with a large gap between the periphery of the box 1 and the inner wall of the cabinet 3, and other boxes 1, the hot air can flow from the second end face 14 of the box 1 towards the front, top, bottom, and rear end of the box 1, and then flow to the air inlet 11 of the box 1. This causes the hot air to be re-drawn into the horizontal frame by the air inlet 11, resulting in hot air recirculation. Therefore, in this embodiment, baffles 2 are provided at different edges of the first end face 13 and the front end face 15 of the box 1, respectively. The width of each baffle 2 is less than or equal to the width of the box 1. The distance between the inner walls of the cabinet 3 ensures the airflow barrier effect of the baffle 2, and the adjacent baffles 2 are also sealed and abut against each other, preventing too much hot airflow from flowing into the gaps between adjacent baffles 2; and since there are also cases where adjacent boxes 1 in the cabinet 3 are stacked on top of each other, the hot airflow cannot flow from the top of the box 1, so there is no need to set the baffle 2 at the top of the box 1 in this case; and in this embodiment, the height of the baffle 2 is the distance between the surface of the box 1 and the inner wall of the surrounding cabinet 3 or other boxes 1 when the box 1 is normally set, ensuring that the baffle 2 does not occupy too much space.

[0075] In this embodiment, a horizontal insert frame is set in the box body 1, and corresponding openings are provided on both sides of the box body 1 for air intake and exhaust. A baffle 2 is provided on the front end face 15 of the box body 1 and the end face where the air inlet 11 is located to block the hot airflow from the air outlet 12. In this way, the hot airflow in the gaps around the box body 1 is blocked without reducing the utilization rate of the cabinet 3, and excessive hot air recirculation is avoided, which would reduce the heat dissipation efficiency.

[0076] In this embodiment, considering that the various boxes 1 may be stacked in the cabinet 3, it is necessary to prioritize blocking the hot airflow from the bottom, front, and rear of the box 1. Therefore, this embodiment is designed as follows:

[0077] like Figure 3 As shown, the baffle 2 located at the first preset position on the first end face 13 of the box body 1 includes: a first baffle 21 and a second baffle 22; the baffle 2 located at the second preset position on the front end face 15 of the box body 1 includes: a third baffle 23 and a fourth baffle 24, wherein:

[0078] like Figure 3 As shown, Figure 3 The direction of the middle arrow indicates the possible flow direction of the hot airflow after it exits from the air outlet 12. The first preset position is the rear end edge and the lower end edge of the first end face 13. The first baffle 21 is disposed at the lower end edge of the first end face 13, and the second baffle 22 is disposed at the rear end edge of the first end face 13. Both the first baffle 21 and the second baffle 22 are perpendicular to the plane containing the first end face 13. Figure 3 As shown, the first baffle 21 is used to block the airflow from the air outlet 12 from flowing from the lower end of the box 1 to the air inlet 11, and the second baffle 22 is used to block the airflow from the air outlet 12 from flowing from the rear end of the box 1 to the air inlet 11.

[0079] It is important to note that, such as Figure 3 As shown, since the box 1 described in this embodiment is rectangular, each end face of the box 1 is rectangular and has four edges. In this embodiment, the rear edge of the first end face 13 refers to the edge of the first end face 13 facing the back of the cabinet 3. A second baffle 22 is provided on this edge. The second baffle 22 is perpendicular to the first end face 13. Since there is a preset gap between the first end face 13 and the inner wall of the cabinet 3, the height of the second baffle 22 is set according to the distance of the gap to ensure that the second baffle 22 just abuts against the inner wall of the cabinet 3, preventing airflow from leaking through the gap between the second baffle 22 and the inner wall of the cabinet 3, thereby blocking the hot airflow from the back of the box 1.

[0080] In this embodiment, the lower edge of the first end face 13 refers to the edge with the lowest vertical height among the four edges of the first end face 13. A first baffle 21 is provided at the lower edge. The first baffle 21 is perpendicular to the first end face 13. Since there is a preset gap between the first end face 13 and the inner wall of the cabinet 3, the width of the first baffle 21 is set according to the distance of the gap to ensure that the first baffle 21 just abuts against the inner wall of the cabinet 3, preventing airflow from leaking through the gap between the first baffle 21 and the inner wall of the cabinet 3, thereby blocking the hot airflow from the bottom of the box 1.

[0081] like Figure 3 As shown, the second preset position is the lower edge and side edge of the front face 15 of the box body 1. The third baffle 23 is disposed at the lower edge of the front face 15 of the box body 1, and the fourth baffle 24 is disposed at the side edge of the front face 15 of the box body 1. Both the third baffle 23 and the fourth baffle 24 are perpendicular to the plane of the front face 15. Figure 3 As shown, the third baffle 23 is used to block the airflow from the air outlet 12 from flowing from the lower end of the box 1 to the air inlet 11, and the fourth baffle 24 is used to block the airflow from the air outlet 12 from flowing from the front end of the box 1 to the air inlet 11.

[0082] In this embodiment, the side edge of the front face 15 refers to either side of the two sides of the front face 15 of the box body 1. At least one fourth baffle 24 is provided. Since there is a preset gap between the front face 15 of the box body 1 and the cabinet door on the front of the cabinet 3, the hot airflow may flow through the gap between the front face 15 of the box body 1 and the cabinet door after being discharged from the air outlet, and reach the vicinity of the air inlet 11. Therefore, in addition to being provided on the side edge of the front face 15, the fourth baffle 24 only needs to be provided to ensure that the upper end of the fourth baffle 24 is above the upper edge of the front face 15, the lower end of the fourth baffle 24 is below the lower edge of the front face 15, and the height of the fourth baffle 24 is set according to the distance between the front face 15 and the cabinet door, so as to ensure that the fourth baffle 24 abuts against the inner wall of the cabinet door, thereby ensuring that the fourth baffle 24 can block most of the airflow at the front of the box body 1. The third baffle 23 is located at the lower edge of the front face 15 of the box body 1. The height of the third baffle 23 is set according to the distance between the front face 15 and the cabinet door, so as to ensure that the third baffle 23 abuts against the inner wall of the cabinet door, and thus ensure that the third baffle 23 can block most of the airflow at the lower end of the box body 1.

[0083] It is important to note that, such as Figure 4As shown, since both the first baffle 21 and the third baffle 23 are rectangular, and the length of the first baffle 21 is the length of the first end face 13, and the length of the third baffle 23 is the length of the front end face 15, a gap exists between the first baffle 21 and the third baffle 23. Hot airflow from the bottom of the housing 1 reaches the vicinity of the air inlet 11 through this gap, still causing a certain degree of hot air recirculation. Therefore, this embodiment also provides a preferred design, such as... Figure 4 As shown, the length of the first baffle 21 or the third baffle 23 is extended to fill the gap. Figure 4 The dotted circle in the diagram represents the extended portion. When the first baffle 21 is extended, the structure of the third baffle 23 remains unchanged. While maintaining the height of the first baffle 21, the first baffle 21 is extended towards the cabinet door until its front end abuts against the inner wall of the cabinet door, thus blocking the gap and preventing hot air from leaking through. When the third baffle 23 is extended, the structure of the first baffle 21 remains unchanged. While maintaining the height of the third baffle 23, the third baffle 23 is extended towards the inner wall of the cabinet 3 until its front end abuts against the inner wall of the cabinet 3, thus blocking the gap and preventing hot air from leaking through.

[0084] Considering the utilization rate of rack 3, in scenarios with low power consumption, the requirements for heat dissipation performance are even lower, and the impact of hot air recirculation is minimal. Therefore, there is no need to install baffle 2. However, to improve the applicability of the enclosure 1 and increase the overall utilization rate of rack 3, this embodiment sets baffle 2 to be openable or closable. When open, baffle 2 performs normal blocking and airflow diversion functions and occupies a certain space. When closed, baffle 2 is not in an upright state, avoiding the occupation of additional space and improving the overall utilization rate of rack 3. On the other hand, since baffle 2 itself has an airflow diversion function, it can prevent airflow from flowing everywhere inside rack 3 and instead direct it to a preset direction. To divert airflow to different directions, different baffles 2 need to be opened or closed for adjustment. Therefore, setting baffle 2 to be openable and closable can further improve the adaptability of enclosure 1 to different rack 3 structures. Therefore, this embodiment also involves the following design:

[0085] All of the baffles 2 have two states: open and closed.

[0086] When the baffle 2 is opened, the baffle 2 is perpendicular to its own end face, the baffle 2 abuts against the inner wall of the corresponding cabinet 3 or the adjacent box 1, and the opened adjacent baffles 2 are mutually sealed and abut against each other.

[0087] When baffle 2 is closed, the state depends on the connection structure between baffle 2 and box 1. There are different states when baffle 2 is closed, as follows:

[0088] like Figure 5 As shown, the first way to set the baffle 2 is that the baffle 2 is axially connected to the edge of the box body 1.

[0089] When the baffle 2 is closed, the baffle 2 rotates outward from the shaft connection position; when the baffle 2 is open, the baffle 2 rotates inward from the shaft connection position, and the open baffle 2 is perpendicular to the end face where it is located.

[0090] The opening and closing mechanism described above utilizes the folding design of the baffle 2. Specifically, the first baffle 21 folds downwards when closed, the second baffle 22 folds towards the rear of the housing 1 when closed, the third baffle 23 folds downwards when closed, and the fourth baffle 24 folds outwards towards the front face 15 when closed. While this folding closing method is relatively simple, it still occupies space and, in most cases, only serves to guide airflow, failing to improve the utilization rate of the cabinet 3.

[0091] In this embodiment, the term "sealed contact" means that the edges of the two baffles 2 are joined together with virtually no gaps, thus preventing airflow from leaking out through any gaps.

[0092] like Figure 6 As shown, the second way to set the baffle 2 is as follows: pulleys are provided on both sides of the baffle 2, a receiving groove is provided inside the end face of the box body 1, and slide rails are provided on both sides inside the receiving groove. The pulleys cooperate with the slide rails, and the baffle 2 moves in and out of the receiving groove.

[0093] When the baffle 2 is opened, the baffle 2 slides out from inside the receiving groove to outside the receiving groove; when the baffle 2 is closed, the baffle 2 slides in from outside the receiving groove to inside the receiving groove.

[0094] like Figure 6 As shown, the opening and closing mechanism described above is similar to a drawer switch. Each end face of the housing 1 has a recess for accommodating the baffle 2. When the baffle 2 is closed, it slides completely into the recess; when the baffle 2 is open, it slides out of the recess. Figure 6The direction of the middle arrow indicates the sliding direction of the baffle. A handle can be installed on the outer end of the baffle 2, allowing manual removal of the baffle 2 from the receiving slot beforehand. A latch is installed at the lower end of the baffle 2 to secure it after removal, preventing it from sliding back into the receiving slot. Alternatively, the slide rail and pulley can be set as electronic slide rails, controlled by the host, eliminating the need for manual adjustment, but this will further increase the cost. On the other hand, when the box 1 is placed in the cabinet 3, the distance between the rear end of the box 1 and the rear end of the inner wall of the cabinet 3 is usually small, often insufficient for the baffle 2 to fold. In this case, a pull-out method is used to control the opening and closing of the baffle 2.

[0095] It should be noted that when the opening and closing of the baffle 2 is controlled by a pull-out method, for example, if the first baffle 21 and the third baffle 23 need to be extended to fill the gap between the two baffles 2, the extended baffle 2 is longer than the length of the end face of the box body 1. The receiving groove of the end face cannot directly store the extended baffle 2. In this case, the extended part is used as an additional baffle 2. A receiving groove is set at one end of the extended part of the original baffle 2 to accommodate the additional baffle 2. The original baffle 2 is then pulled out of the box body 1, and the additional baffle 2 is then pulled out of the receiving groove of the original baffle 2, thereby realizing the storage of the original baffle 2 in the box body 1.

[0096] When the boxes 1 in the rack 3 are stacked, i.e., the upper box 1 abuts against the adjacent lower box 1, thus saving rack 3 space, the hot air cannot flow from the upper and lower ends of the box 1 to the air inlet 11 because the upper and lower ends of the box 1 are abutted by other boxes 1. It can only flow from the front or rear end of the box 1. In this case, the upper surface of the box 1 does not need to be equipped with a baffle 2. However, when the boxes 1 in the rack 3 are not stacked, but there is a certain gap between the upper and lower adjacent boxes 1, this avoids direct contact between the boxes 1 and reduces mutual heat transfer. At the same time, the hot air from the air outlet 12 can flow from the upper and lower ends of the box 1. The lower end of the box 1 is already blocked by the third baffle 23 and the fourth baffle 24, and the upper end of the box 1 also needs to be blocked by a baffle 2. Therefore, this embodiment also involves the following design:

[0097] like Figure 7 As shown, the baffle 2 further includes a fifth baffle 25, wherein:

[0098] The fifth baffle 25 is disposed on the upper surface of the housing 1. When the fifth baffle 25 is opened, one end of the fifth baffle 25 is sealed against the upper end of the opened second baffle 22, and the other end is sealed against the upper end of the opened fourth baffle 24. The fifth baffle 25 is used to block the airflow from the air outlet 12 from flowing from the upper end of the housing 1 to the air inlet 11. When the fifth baffle 25 is opened, the upper end of the fifth baffle 25 is sealed against the bottom of the upper layer housing 1 or the inner wall of the top layer of the cabinet 3.

[0099] like Figure 8 As shown, when a fifth baffle 25 needs to be installed above the box body 1, the gap between the fifth baffle 25, the second baffle 22, and the fourth baffle 24 needs to be considered. Therefore, one end of the fifth baffle 25 needs to be placed at the rear edge of the first end face 13 of the box body 1, and the gap between the fifth baffle 25 and the second baffle 22 needs to be filled by extending the fifth baffle 25 or the second baffle 22, as shown. Figure 8 As shown, in this embodiment, the second baffle 22 is extended vertically upwards, with the dotted circle representing the extended portion, until it reaches the height of the fifth baffle 25 and seals against one end of the fifth baffle 25; as Figure 8 As shown, the other end of the fifth baffle 25 is positioned vertically to the location of the fourth baffle 24, and similarly, the gap between the fifth baffle 25 and the fourth baffle 24 is filled by extending either the fifth baffle 25 or the fourth baffle 24, as shown. Figure 8 As shown, in this embodiment, the fourth baffle 24 is extended vertically upwards until it reaches the height of the fifth baffle 25. The dotted circle represents the extended portion, which is sealed and abuts against one end of the fifth baffle 25. The extension method described above is consistent with the extension method of the first baffle 21 or the third baffle 23 mentioned above, and will not be elaborated further here.

[0100] In this embodiment, since the upper surface of the box 1 does not have enough vertical space to provide a receiving groove for the fifth baffle 25, the fifth baffle 25 is opened and closed by folding. The fifth baffle 25 is axially connected to the upper surface of the box 1. When the fifth baffle 25 is closed, it folds towards the upper surface of the box 1. When the fifth baffle 25 is open, it folds towards the outside of the box 1 and is perpendicular to the upper surface of the box 1. When the box 1 is in the middle of the cabinet 3, the upper end of the fifth baffle 25 abuts against the bottom of the upper box 1. When the box 1 is at the top of the cabinet 3, the upper end of the fifth baffle 25 abuts against the top of the inner side of the cabinet 3. Figure 7 As shown, the hot airflow is blocked on the right side of the fifth baffle 25.

[0101] Because in the existing technology, the exhaust vents for discharging hot air are located in different positions on racks 3 with different structures. Some exhaust vents are located on the front rack door, some on the top of the rack, and some on the rear of the rack. For exhaust vents in different locations, it is necessary to guide the hot air coming out of the air outlet 12 to accelerate the efficiency of hot air discharge and prevent hot air from stagnating inside the rack 3, which would reduce the sustained high temperature inside the rack and reduce heat dissipation efficiency. Therefore, this embodiment also involves the following design:

[0102] like Figure 9 As shown, the baffle 2 further includes a sixth baffle 26, a seventh baffle 27, and an eighth baffle 28, wherein:

[0103] like Figure 9 As shown, the sixth baffle 26 is disposed at the front edge of the second end face 14, the seventh baffle 27 is disposed at the upper edge of the second end face 14, and the eighth baffle 28 is disposed at the rear edge of the second end face 14. The sixth baffle 26 is used to block the airflow from the air outlet 12 from being discharged from the front end of the housing 1, the seventh baffle 27 is used to block the airflow from the air outlet 12 from being discharged from the upper end of the housing 1, and the eighth baffle 28 is used to block the airflow from the air outlet 12 from being discharged from the rear end of the housing 1. Figure 7 The arrows in the diagram indicate the direction of the hot airflow output, and it can be seen that they are all blocked by the sixth baffle 26, the seventh baffle 27, and the eighth baffle 28.

[0104] By controlling the opening or closing of the sixth baffle 26, the seventh baffle 27 and the eighth baffle 28, the airflow of the air outlet 12 can be controlled to be discharged from the front end, the upper end or the lower end of the second end face 14 of the box body 1.

[0105] It is important to note that Figure 9 The eighth baffle 28 is connected to the rear end edge of the same box 1. Figure 9 The eighth baffle 28 is blocked by the seventh baffle 27, so the eighth baffle 28 is represented by a dashed line. In order to avoid confusion with the seventh baffle 27 when labeling, the number of the eighth baffle 28 is connected to the upper edge of the eighth baffle 28.

[0106] The sixth baffle 26, seventh baffle 27, and eighth baffle 28 can also be switched by flipping or pulling. When the flipping method is used, the sixth baffle 26, seventh baffle 27, and eighth baffle 28 are all connected to the corresponding edges of the second end face 14. When open, the sixth baffle 26, seventh baffle 27, and eighth baffle 28 fold towards the position of the second end face 14 and are perpendicular to the second end face 14. When closed, the sixth baffle 26, seventh baffle 27, and eighth baffle 28 fold outwards towards the second end face 14. When closed, the sixth baffle 26 is perpendicular to the front end face of the box 1, the seventh baffle 27 is perpendicular to the upper end face of the box 1, and the eighth baffle 28 is perpendicular to the rear end face of the box 1. When the pulling method is used for opening and closing, such as Figure 9 As shown, relative to Figure 9 In terms of orientation, receiving slots are respectively provided on the right side of the front end face 15 of the box body 1, the right side of the upper end face of the box body 1, and the right side of the rear end face of the box body 1, for accommodating the sixth baffle 26, the seventh baffle 27, and the eighth baffle 28, and the sixth baffle 26, the seventh baffle 27, and the eighth baffle 28 can be pulled out in them to open and close accordingly.

[0107] Correspondingly, such as Figure 10 As shown, when the sixth baffle 26 and the seventh baffle 27 are opened and the eighth baffle 28 is closed, only the rear end of the second end face 14 is unobstructed. When the hot airflow is discharged from the air outlet 12 of the box body 1, the upper end is blocked by the seventh baffle 27 of the box body 1 itself, the lower end is blocked by the seventh baffle 27 of the lower box body 1, and the front is blocked by the sixth baffle 26. Only the rear end baffle 2 is not opened. Figure 10 As shown, Figure 10 The middle arrow indicates the direction of hot airflow; it can be seen that only the airflow at the rear of cabinet 1 is unobstructed. Therefore, the exhaust vent for rack 3 should be positioned at the rear of rack 3. Figure 8 As shown, the second end face 14 of the box 1 is located on the right side of the figure. Therefore, the exhaust vent is set on the right side of the rear end of the cabinet 3. Since there are multiple boxes 1 in the cabinet 3, exhaust vents are set at the height of each box 1 from top to bottom on the right side of the rear end face of the cabinet 3, so as to exhaust all hot air.

[0108] Correspondingly, such as Figure 11 As shown, when the eighth baffle 28 and the seventh baffle 27 are opened and the sixth baffle 26 is closed, only the front end of the second end face 14 is unobstructed. When the hot airflow is discharged from the air outlet 12 of the box body 1, the upper end is blocked by the seventh baffle 27 of the box body 1 itself, the lower end is blocked by the seventh baffle 27 of the lower box body 1, and the rear side is blocked by the eighth baffle 28. Only the front end baffle 2 is not opened. Figure 11 As shown, Figure 11The middle arrow indicates the direction of hot airflow; it can be seen that only the airflow at the front of box 1 is unobstructed. Therefore, the exhaust vent for rack 3 should be positioned on the front door of rack 3. Figure 11 As shown, the second end face 14 of the box 1 is located on the right side of the figure. Therefore, the exhaust vent is set on the right side of the cabinet door. Since there are multiple boxes 1 in the cabinet 3, exhaust vents are set at the height of each box 1 from top to bottom on the right side of the cabinet door, so as to exhaust all hot air.

[0109] Correspondingly, such as Figure 12 As shown, when the eighth baffle 28 and the sixth baffle 26 are opened and the seventh baffle 27 is closed, only the upper and lower ends of the second end face 14 are unobstructed. When the hot airflow is discharged from the air outlet 12 of the box body 1, the front end is blocked by the sixth baffle 26 and the rear side is blocked by the eighth baffle 28. Only the upper and lower ends are not open by the baffle 2. Figure 12 As shown, Figure 12 The middle arrow indicates the direction of hot airflow. It can be seen that only the upper and lower ends of box 1 are not obstructed. Therefore, the exhaust vents for rack 3 should be positioned at the top of rack 3. Figure 12 As shown, the second end face 14 of the box 1 is located on the right side of the figure. Therefore, the exhaust vent is set on the right side of the top of the cabinet 3. When the hot air is discharged from the air outlet 12 of the box 1, all the hot air from the top to the bottom of the box 1 is concentrated on the right side of the cabinet 3 and discharged from the exhaust vent set on the right side of the top of the cabinet 3.

[0110] Example 2:

[0111] Based on Embodiment 1, Embodiment 2 of the present invention provides a hybrid airflow cooling method for horizontal insertion devices, which is applied to the hybrid airflow cooling device for horizontal insertion devices in Embodiment 1.

[0112] like Figure 13 As shown, the steps include:

[0113] In step 101, the horizontal insertion frame is placed inside the box body 1, with the air inlet side of the horizontal insertion frame facing the air inlet 11 of the first end face 13 and the air outlet side of the horizontal insertion frame facing the air outlet 12 of the second end face 14.

[0114] In step 102, according to the position of the exhaust vent on the cabinet 3, the baffles 2 on the box 1 are opened or closed to block the airflow between the air outlet 12 and the air inlet 11, and the airflow from the air outlet 12 is directed to the position of the exhaust vent.

[0115] The aforementioned adjustments to the baffles 2 on box 1 need to be completed before box 1 is placed into rack 3. The adjustments need to be determined based on the power consumption of the communication equipment in the horizontal insertion frame, the location of the exhaust vents, and whether the boxes 1 are stacked.

[0116] When the power consumption of the communication device in the horizontal insertion frame is too low, such as when the transmission rate is below 100G, there is no need to open the baffle 2. At this time, the device has low requirements for heat dissipation efficiency and there is no need to worry about the impact of hot air recirculation.

[0117] In step 103, the cold air enters from the air inlet 11 on the first end face 13 of the box 1, and the hot air exits from the air outlet 12 on the second end face 14 of the box 1 and is discharged from the exhaust vent on the cabinet 3.

[0118] When the power consumption of the communication equipment in the horizontal insertion frame is high, such as when the transmission rate is above 100G, it is necessary to open the corresponding baffle 2 to block or divert the hot airflow in the cabinet 3, so as to reduce the impact of hot air recirculation on heat dissipation efficiency.

[0119] When the exhaust vent is located on the front end face 15 of the cabinet 3, the first baffle 21 and the second baffle 22 located on the first end face 13 of the box body 1 are opened, the third baffle 23 and the fourth baffle 24 located on the front end face 15 of the box body 1 are opened, the seventh baffle 27 and the eighth baffle 28 located on the second end face 14 of the box body 1 are opened, and the sixth baffle 26 located on the second end face 14 of the box body 1 is closed.

[0120] In this embodiment, the first baffle 21, the second baffle 22, the third baffle 23 and the fourth baffle 24 serve as barrier baffles 2 near the air inlet 11, used to block hot airflow from the front end, rear end and bottom end of the box body 1. The baffles 2 must be opened in the following situations, which will not be described in detail later.

[0121] When the eighth baffle 28 and the seventh baffle 27 are open, and the sixth baffle 26 is closed, only the front end of the second end face 14 is unobstructed. When the hot airflow is discharged from the air outlet 12 of the box body 1, the upper end is blocked by the seventh baffle 27 of the box body 1 itself, the lower end is blocked by the seventh baffle 27 of the lower box body 1, and the rear side is blocked by the eighth baffle 28. Only the front baffle 2 is not open. Figure 11 As shown, Figure 11 The middle arrow indicates the direction of hot airflow; it can be seen that only the airflow at the front of box 1 is unobstructed. Therefore, the exhaust vent for rack 3 should be positioned on the front door of rack 3. Figure 11As shown, the second end face 14 of the box 1 is located on the right side of the figure. Therefore, the exhaust vent is set on the right side of the cabinet door. Since there are multiple boxes 1 in the cabinet 3, exhaust vents are set at the height of each box 1 from top to bottom on the right side of the cabinet door, so as to exhaust all hot air.

[0122] When the exhaust vent is located on the upper surface of the cabinet 3, the first baffle 21 and the second baffle 22 located on the first end face 13 of the box body 1 are opened, the third baffle 23 and the fourth baffle 24 located on the front end face 15 of the box body 1 are opened, the sixth baffle 26 and the eighth baffle 28 located on the second end face 14 of the box body 1 are opened, and the seventh baffle 27 located on the second end face 14 of the box body 1 is closed.

[0123] When the eighth baffle 28 and the sixth baffle 26 are open, and the seventh baffle 27 is closed, only the upper and lower ends of the second end face 14 are unobstructed. When the hot airflow is discharged from the air outlet 12 of the box 1, the front end is blocked by the sixth baffle 26, and the rear side is blocked by the eighth baffle 28. Only the upper and lower baffles 2 are not open. Figure 12 As shown, Figure 12 The middle arrow indicates the direction of hot airflow. It can be seen that only the upper and lower ends of box 1 are not obstructed. Therefore, the exhaust vents for rack 3 should be positioned at the top of rack 3. Figure 12 As shown, the second end face 14 of the box 1 is located on the right side of the figure. Therefore, the exhaust vent is set on the right side of the top of the cabinet 3. When the hot air is discharged from the air outlet 12 of the box 1, all the hot air from the top to the bottom of the box 1 is concentrated on the right side of the cabinet 3 and discharged from the exhaust vent set on the right side of the top of the cabinet 3.

[0124] When the exhaust vent is located on the rear end face of the cabinet 3, the first baffle 21 and the second baffle 22 located on the first end face 13 of the box body 1 are opened, the third baffle 23 and the fourth baffle 24 located on the front end face 15 of the box body 1 are opened, the sixth baffle 26 and the seventh baffle 27 located on the second end face 14 of the box body 1 are opened, and the eighth baffle 28 located on the second end face 14 of the box body 1 is closed.

[0125] When the sixth baffle 26 and the seventh baffle 27 are open, and the eighth baffle 28 is closed, only the rear end of the second end face 14 is unobstructed. When the hot airflow is discharged from the air outlet 12 of the box body 1, the upper end is blocked by the seventh baffle 27 of the box body 1 itself, the lower end is blocked by the seventh baffle 27 of the lower box body 1, and the front is blocked by the sixth baffle 26. Only the rear end baffle 2 is not open. Figure 10 As shown, Figure 10 The middle arrow indicates the direction of hot airflow; it can be seen that only the airflow at the rear of cabinet 1 is unobstructed. Therefore, the exhaust vent for rack 3 should be positioned at the rear of rack 3. Figure 8As shown, the second end face 14 of the box 1 is located on the right side of the figure. Therefore, the exhaust vent is set on the right side of the rear end of the cabinet 3. Since there are multiple boxes 1 in the cabinet 3, exhaust vents are set at the height of each box 1 from top to bottom on the right side of the rear end face of the cabinet 3, so as to exhaust all hot air.

[0126] When two adjacent boxes 1 in the cabinet 3 are in contact with each other, the fifth baffle 25 on the upper surface of the box 1 is closed; when there is a gap between two adjacent boxes 1 in the cabinet 3, the fifth baffle 25 on the upper surface of the box 1 is opened.

[0127] When the boxes 1 in the rack 3 are stacked together, the hot air will not flow from the top of the box 1, so there is no need to open the fifth baffle 25, and there is no space for the fifth baffle 25 to be opened; when the boxes 1 in the rack 3 are spaced apart, the hot air will flow from the top of the box 1, and the fifth baffle 25 needs to be opened to block the hot air on the right side of the fifth baffle 25.

[0128] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
