detailed description

The present disclosure will be described in detail below with reference to the accompanying drawings.

This embodiment provides a wind guide cabinet, which is used in conjunction with a cabinet to dissipate heat from a cabinet. When at least one of the foregoing air guide cabinets is provided for one cabinet, a communication system is formed. Please refer to FIG. 1. FIG. 1 is a schematic view showing the working relationship between the air guiding cabinet and the cabinet provided in the embodiment. The air guiding cabinet 2 is disposed on the side of the cabinet 1. The air guiding cabinet 2 includes a wind guiding cabinet 20 and is disposed in the air guiding body. The air inlet duct 21 and the air outlet duct 22 on the cabinet 2 are used to introduce external cold air into the cabinet 1 to cool the components to be radiators, such as single boards, in the cabinet 1. When the cold air takes away the heat inside the cabinet 1, the temperature of the cabinet gradually rises and becomes hot air. At this time, the hot air enters the air outlet duct 22 of the air guiding cabinet 2 from the cabinet 1, and the air is exhausted from the air outlet duct 22. Cabinet 2.

2, the air outlet 211 of the air inlet duct 21 and the air inlet 221 of the air outlet duct 22 are both disposed on the side of the air guiding cabinet 20, and the air outlet 211 of the air inlet duct 21 is disposed in the cabinet 1. The side air inlet holes cooperate to allow cold air to enter the cabinet 1 from the air guiding cabinet 2;

The air inlet 221 of the air outlet duct 22 cooperates with the air outlet hole provided at the side of the cabinet 1, so that hot air enters the air guiding cabinet 2 from the cabinet 1.

The intake air duct 21 and the air outlet duct 22 in the air duct 2 can be implemented in various ways. For example, a special duct can be provided in the air duct 2 to introduce cold air and exhaust hot air, that is, "pipe type". In this case Next, only the airtightness of the intake air duct 21 and the air outlet duct 22 is required, and the airtightness of the air guiding cabinet 2 does not need to be considered too much. In many cases, the length of the cables in the cabinet 1 may not be exactly the same, but is longer than the actual requirements. In order to make the space in the cabinet 1 more tidy and orderly, these extra cables will be used. Management is required. The most common method in the related art is to provide a fiberizing device in the air guiding cabinet 2 for storing and managing excess cables. When a special pipe is provided in the air guiding cabinet 2 to introduce cold air and discharge hot air, a disk device may be disposed in the air guiding cabinet 2 except for the air duct 21 and the air outlet duct 22, without specializing It is convenient to avoid specific locations. In addition to the implementation of an inlet duct 21 and an outlet duct 22 provided by the above-mentioned "ducted" air duct, an alternative is given below, as shown in FIG. 3, in the air duct 2 In the case of better overall air tightness, the wind guide cabinet 20 can be directly divided into two upper and lower parts, and the upper part and the lower part are separated by a partition 23, and a corresponding air inlet is opened in the air guiding cabinet 2 / After the air outlet, the portion below the partition 23 is referred to as the air inlet duct 21, and the portion above the partition 23 is referred to as the air outlet duct 22, which is referred to as a "separator type". Compared with the “pipeline” air guiding cabinet, the “baffle type” air guiding cabinet has a simpler structure, and the process is simpler in the production stage of the equipment. At the same time, when multiple inlet air ducts or multiple air outlet ducts need to be added, the “separator type” air guiding cabinet only needs to add a new partition in the air guiding cabinet, so that the content chamber of the air guiding cabinet Divided into more parts, it is much simpler than the "pipeline" air ducts need to be arranged to set up new pipes.

Similarly, the air inlet 221 of the air duct of the air duct 2 needs to correspond to the position of the air outlet hole on the cabinet 1 to ensure that the hot air in the cabinet can smoothly pass through and enter the air duct 22 . In the case where the side of the air guiding cabinet 2 is in close contact with the side of the cabinet 1, if it can be ensured that the air outlet 211 of the air inlet duct and the air inlet hole of the cabinet 1 have the same size and completely overlap, a certain time can be guaranteed. The amount of cold air entering the cabinet 1 is the largest. Correspondingly, if the air inlet 221 of the air outlet duct is the same as the size of the air outlet of the cabinet 1 and completely coincides, then in this case, a certain time The amount of hot air discharged from the cabinet 1 is also the largest.

In addition to the above manner of making the side of the air guiding cabinet 2 close to the side of the cabinet 1, there is a second solution, please refer to FIG. 4, which is a perspective view of a communication system provided by the embodiment, the air guiding cabinet 2 and The position of the cabinet 1 is also not limited, and the air outlet 211 of the air inlet duct in the air guiding cabinet 2 and the air inlet hole on the side of the cabinet 1 Pipe connection is also adopted. Similarly, the air outlet hole on the side of the cabinet 1 and the air inlet port 221 of the air outlet duct of the air guide cabinet 2 are also connected by pipes. In this case, the air outlet 211 of the air inlet duct is not required. The positional relationship of the air inlet holes on the side of the cabinet 1 and the positional relationship between the air outlet holes on the side of the cabinet 1 and the air inlet 221 of the air outlet duct are limited. This arrangement is suitable for the cabinet 1 and the air duct 2 A situation that cannot be placed in one place due to external factors. In FIG. 4, the air inlet 221 of the air outlet duct on the air guiding duct 2 and the air outlet 211 of the air inlet duct and the duct are all circular, and the air outlet 211 and the duct may be arranged in a square shape and an ellipse. The shape or the irregular shape, in addition, the air inlet 221 of the air outlet duct, the air outlet 211 of the air inlet duct, the air inlet hole on the side of the cabinet, the size and position of the air outlet hole, and the shape of the duct are not limited.

When the air guiding cabinet 2 provided in this embodiment can simultaneously set a plurality of air inlet ducts and a plurality of air outlet ducts for heat dissipation, as shown in FIG. 5, when the cabinet 1 needs to be dispersed and cooled, the cabinet 1 is internally partitioned. It is divided into two upper and lower parts. At this time, the upper and lower parts can be separately set into the inlet air duct and the outlet air duct for heat dissipation. At this time, the inlet air duct includes the upper inlet air duct 21" and the lower inlet air duct. 21', when the outlet air duct includes the upper air duct 22" and the lower air duct 22', correspondingly, the air inlet hole provided on the side of the cabinet 1 includes an upper air inlet hole, a lower air inlet hole, and an air outlet hole. Includes upper and lower air holes.

It is known to those skilled in the art that in the related art, a special cold air duct is disposed in the equipment room to dissipate heat from the communication system, and the hot air discharged after the heat dissipation is not processed, and the cold air is separated by the cold air duct; or the cold air duct is set. At the same time, special pipes are arranged to collect hot air, and the hot and cold separation is realized through different pipes. Therefore, in order to ensure the convenience of conveying cold air and collecting hot air, the air inlet and the air outlet of the air duct of the air guiding cabinet 2 in this embodiment are not set as much as possible. On the same side, for example, the air inlets are all provided on the front or bottom surface of the cabinet 1, and the air outlets are all disposed on the back or top surface of the cabinet 1.

The air inlet of the lower air inlet duct may be located at the front and/or the bottom surface of the air guiding cabinet 2, and the air outlet of the lower air inlet duct cooperates with the lower air inlet hole provided at the side of the cabinet 1 to allow the lower air inlet duct to The cold air introduced into the bottom of the air duct and/or the front side enters the cabinet to cool the cabinet. The air inlet of the lower air duct is placed at the side of the air duct 2 corresponding to the air outlet of the cabinet 1 and the wind is discharged. The air outlet of the air duct is disposed at the back of the air guiding cabinet 2, and the hot air enters the lower air duct through the lower air outlet hole of the cabinet 1 and the air inlet of the lower air duct, and then is discharged; the upper air inlet duct enters The air outlet is located at the front side of the air guiding cabinet 2, and the air outlet of the upper air inlet duct cooperates with the upper air inlet hole disposed at the side of the cabinet 1 to allow the cold air introduced from the front side of the air guiding duct 2 to enter the cabinet 1 to the cabinet 1 The air inlet of the upper air duct is disposed at a position corresponding to the air outlet of the cabinet, and the air outlet of the upper air duct is disposed at the back and/or the top of the air duct 2 Hot air enters through the upper air outlet on the cabinet 1 and the air inlet on the upper air duct An air damper Road, then dried over The air outlet of the air outlet duct is discharged from the rear and/or top surface of the air guiding cabinet 2.

The structure of the air guiding cabinet in this embodiment will be described below by taking the "separator type" air guiding cabinet as an example. Please refer to FIG. 6:

In this example, the cabinet 1 uses two air guiding cabinets 2 and 2' for heat dissipation, and the air guiding cabinets 2 and 2' are respectively disposed on the left and right sides of the cabinet 1, and the structures of the two air guiding cabinets 2 and 2' are corresponding. Take the left side air duct 2 as the description object:

The inside of the air guiding cabinet 2 is respectively provided with a first partition, a second partition and a third partition from bottom to top, and the three partitions divide the inside of the air guiding cabinet into four chambers, which are respectively from bottom to top a chamber, a second chamber, a third chamber, and a fourth chamber. Referring to FIG. 7, a hole is formed in the front surface of the air guiding cabinet 2 corresponding to the first chamber to form an air inlet 212' of the lower air inlet duct 21'; in the front side of the air guiding cabinet 2 and the third chamber Corresponding place opening, forming and inlet air duct 21" air inlet 212"; please refer to Figure 8, in the back of the air guiding cabinet 2 corresponding to the second chamber to set the opening to form the lower air duct 22's air outlet 222', an opening is provided at a position corresponding to the fourth chamber on the back side of the air guiding cabinet 2, forming an air outlet 222" of the upper air duct 22"; even if the upper and lower portions of the cabinet 1 are separately For heat dissipation, it is not necessary to open two air inlets on the front side of the air guiding cabinet 2, because the lower air inlet duct 21' can enter the air from the bottom surface, so the air inlet of the lower air inlet duct 21' can be set in the air guiding manner. The bottom surface of the cabinet 2; similarly, the upper air outlet 22" can be ventilated from the top surface of the air guiding cabinet 2, therefore, it is not necessary to open two air outlets on the back of the air guiding cabinet 2. In the air guiding cabinet 2 The side surface corresponding to the four chambers is respectively provided with four openings, as shown in Fig. 7, from bottom to top, respectively, the outlet of the lower inlet air duct Port 211 ', the air inlet passage of the air damper 221', aspirant air damper outlet channel 211 ", the air damper on the inlet of the channel 221."

As can be seen from Fig. 6, the interior of the cabinet 1 is divided into two parts from top to bottom, separated by a partition, and the horizontal position of the partition is almost the same as the horizontal position of the second partition in the air guiding cabinet. level. The side of the cabinet 1 adjacent to the air guiding cabinet 2 is also provided with a corresponding air inlet hole/air outlet hole, and the lower air inlet hole, the lower air outlet hole, the upper air inlet hole and the upper air outlet are respectively from bottom to top. The holes, the four inlet holes/outlet holes are respectively connected with the air outlet 211' of the lower air inlet duct on the side of the air guiding cabinet, the air inlet 221' of the lower air duct pair, and the air outlet 211 of the upper inlet air duct. ", the air inlet 221 of the upper air duct is matched" to achieve ventilation.

The first air blower group 71 disposed on the lower side of the inner side of the cabinet 1 allows the air inlet of the lower air inlet duct 21' to introduce cold air from the bottom surface of the air guiding cabinet 2 or the front lower portion of the air guiding cabinet 2, and the air inlet through the lower air inlet duct The air inlet cooperates with the air inlet hole of the cabinet 1 to transport the cold air to the inside of the cabinet 1. The cold air passes through the first PCB (Printed Circuit Board) board group 81, and takes away the heat of the first PCB board group 81. Hot air is formed, and then reaches the partition at the middle of the cabinet 1. The hot air is blocked by the partition and cannot continue upward. It can only pass through the side of the cabinet 1. The lower air outlet of the face enters the lower air duct 22' in the air guiding cabinet 2, and is discharged from the air outlet of the lower air duct provided at the back of the air guiding cabinet 2.

Due to the function of the second fan group 72 disposed on the upper side of the cabinet, the air inlet of the upper air inlet duct introduces cold air from the middle of the front side of the air guiding cabinet 2, and cooperates with the air inlet of the upper air inlet duct and the upper air inlet hole of the cabinet 1 The cold air is delivered to the inside of the cabinet 1 and is blocked by the partition plate. The cold air does not flow to the lower part of the cabinet 1 and can only pass through the second PCB board group 82 and the third PCB board group 83, and the second PCB board group is taken away. After the heat of the 82 and the third PCB board group 83 forms hot air, it reaches the top of the cabinet 1 and passes through the upper and lower air outlet holes on the side of the cabinet 1 to enter the upper and lower air duct 22" in the air guiding cabinet, from the wind guiding cabinet. 2 The air outlet of the upper air outlet of the back and/or top is discharged.

In this embodiment, in order to increase the air volume of the cold air, a hole may be opened in the bottom surface and/or the front surface of the cabinet 1 for introducing cold air. Similarly, in order to quickly discharge hot air, it may also be on the top surface of the cabinet 1 and/or Holes are provided on the back.

In the above example, the air guiding cabinet 2 uses three partitions to form four air ducts, but it is undoubted that the inner side of the air guiding cabinet 2 can also use more partitions to isolate a plurality of chambers, thereby According to the above setting rules, more air inlet/outlet air ducts are formed. Similarly, only one partition plate may be provided to form two air ducts or two partition plates may be provided to form three air ducts. The air duct is two air inlet ducts, one air duct, or one air duct and two air ducts, which can be determined according to actual conditions.

In another example given in this embodiment, the air outlet of the air inlet duct on the side of the air guiding cabinet 2 and the air inlet of the air outlet duct may be disposed as large as the side of the air guiding cabinet, and the side of the cabinet is The size of the air inlet hole and the air outlet hole are set to be as large as the side of the cabinet, that is, the two adjacent sides of the air guiding cabinet and the cabinet are removed, as shown in FIG. 9, in which the setting is set. A partition plate divides the inside of the air guiding cabinet 2 into two parts, and the front side and the back side of the air guiding cabinet 2 respectively open holes, respectively forming an air inlet of the air inlet duct 21 and an air outlet of the air outlet duct 22, and the air guiding cabinet 2 The side panel adjacent to the cabinet is removed. At this time, the area of the air inlet 211 of the air inlet duct and the air inlet 221 of the air outlet duct is determined according to the position of the partition. Compared with other methods, the arrangement of the air inlet of the air inlet duct and the air inlet of the air outlet duct is relatively large, so that it is easier to enter the cabinet and the hot air enters the air duct. At the same time, the solution has the additional advantages: firstly, the side panels of the air guiding cabinet 2 and the side panels of the cabinet are not disposed, which saves materials; secondly, the wind ducts are opened on the side panels of the air guiding cabinet 2 The air outlet, the air inlet air outlet, and the air inlet and outlet air passages are arranged on the side panel of the cabinet. The number of the air inlet duct and the air outlet duct is only based on the air deflector 2 and the partition in the cabinet. The setting is determined. For example, if three partitions are arranged in the air guiding cabinet and a partition is arranged in the cabinet, the upper and lower parts of the cabinet can be separately cooled. This arrangement also saves the production process.

The shape of the air inlet/air outlet on the air guiding cabinet and the air inlet/air outlet on the cabinet are not the only implementation manners, and the principles of the present disclosure are clearly described to make the technology in the field clear. The person understands the concept of the present disclosure, so the shape, size, and the like of the air inlet/air outlet of the air guiding cabinet and the air inlet/air outlet on the cabinet in the drawings should not be limited to the scope of protection of the present disclosure.

Only the description of the left air guiding cabinet 2 is given above, and the right air guiding cabinet 2' has the same principle as the left air guiding cabinet 2, and the structure is symmetrical, and will not be described again here.

The above is a detailed description of the disclosure in connection with the alternative embodiments.
