[0042] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0043] The embodiments of the present application provide a guide device and a cabinet with a fiber coiling function to solve the problem in the related art that a horizontally inserted device with cold air inlet on the left and hot air outlet on the right is placed in the cabinet, and the temperature on the air inlet side increases due to the backflow of hot air, thus affecting the heat dissipation.

[0044] The front door of the following cabinet is marked with B, and the rear door of the cabinet is marked with A. Figure 1 The lighter arrows are cold air, and the darker arrows are hot air.

[0045] See also Figure 2-Figure 7 , a flow guiding device with fiber coiling function, comprising:

[0046] The partition structure 1 has a cabinet rear door fitting surface 11, a cabinet front door fitting surface 12, an air inlet side surface 13 and an air outlet side surface 14;

[0047] Two air guide channels 2 are located in the partition structure 1 and are spaced apart in the direction from the air inlet side 13 to the air outlet side 14; the two ends of one of the channels are respectively passed through the cabinet front door fitting surface 12 and the air inlet side 13, and the two ends of the other connecting channel are respectively passed through the cabinet front door fitting surface 12 and the air outlet side 14.

[0048] In the above structure, the partition structure 1 of the flow guide device with fiber coiling function has a cabinet rear door fitting surface 11, a cabinet front door fitting surface 12, an air inlet side surface 13 and an air outlet side surface 14; two air guide channels 2 are located in the partition structure 1, and are spaced apart in the direction from the air inlet side surface 13 to the air outlet side surface 14; the two ends of one of the channels are respectively penetrated by the cabinet front door fitting surface 12 and the air inlet side surface 13, and the two ends of the other connecting channel are respectively penetrated by the cabinet front door fitting surface 12 and the air outlet side surface 14; when installed in the cabinet Due to the existence of the cabinet rear door fitting surface 11 and the cabinet front door fitting surface 12 of the above partition structure 1, isolation is performed in the direction from cold air to hot air, and isolation is also performed between the horizontally plugged devices in the direction of the cabinet; through the use of the above structure, cold air enters the left side of the horizontally plugged device and the left side of the guide device from the cabinet front door; hot air is discharged from the right side of the horizontally plugged device, part of it is discharged through the air duct on the right side of the cabinet, and part of it is discharged from the cabinet front door through the right front of the guide device, thereby realizing the isolation of cold and hot air and avoiding the problem of affecting heat dissipation.

[0049] It should be understood from the above that the partition structure 1 can be a plastic plate or metal plate of a certain thickness, which has two unconnected air guide channels 2 and a fitting surface that fits the front and back surfaces of the cabinet. In addition, since the plastic plate or metal plate itself does not have through holes on the cold air inlet side and the hot air outlet side, it is isolated in this direction. This solves the problem that when a left-in-right-out horizontal plug-in device is placed in a cabinet, the hot air blown out from the right side of the device is blocked by the right side panel, rear door and front door of the cabinet, and part of the hot air is re-entered into the left air inlet area of ​​the device, causing the temperature of the left air inlet to rise, which has an adverse effect on the heat dissipation of a single disk.

[0050] In some preferred embodiments, there are optical fiber connections between communication devices and between different single trays of the same device, and a fiber tray box is needed to organize the excess length of the optical fiber. The horizontal plug-in device requires a fiber tray box configured outside the device; therefore, the horizontal plug-in device has both a flow guide device and a fiber tray box in the cabinet. The flow guide device and the fiber tray box will occupy the internal space of the cabinet, thereby affecting the number of horizontal plug-in devices installed and reducing the space utilization rate of the cabinet. Therefore, in order to improve the space utilization rate of the cabinet, the following settings are made:

[0051] Also includes a fiber coil box 3;

[0052] join Figure 5 and Figure 6 , a placement space 4 is provided in the partition structure 1 and between the two air guide channels 2; a mounting notch 15 communicating with the placement space 4 is provided on the fitting surface 12 of the cabinet front door;

[0053] The fiber coil box 3 is installed in the placement space 4 and blocks the installation slot 15. The functions of the partition structure and the fiber coil box are combined into one, thereby reducing the space occupied and making the size of the horizontal insertion device larger.

[0054] Furthermore, in order to reduce the overall weight of the partition structure 1 and meet the installation requirements of the fiber tray box 3, the following settings are provided:

[0055] The partition structure 1 includes a bottom plate 100, a top plate 101, a front plate 102, a rear plate 103, a cold air side plate 104 and a hot air side plate 1010 connected to each other; a first partition plate 105 and a second partition plate 108 are arranged between the bottom plate 100 and the top plate 101; two first notches 106 are arranged on the front plate 102, a second notch 107 is arranged on the cold air side plate 104, and a third notch 109 is arranged on the hot air side plate 1010;

[0056] A placement space 4 is formed between the first partition plate 105 and the second partition plate 108;

[0057] The first partition plate 105, the rear plate 103, the bottom plate 100, the top plate 101, the cold air side plate 104, the second notch 107 and one of the first notches 106 form an air guide channel 2 for guiding cold air;

[0058] The second partition plate 108 , the rear plate 103 , the bottom plate 100 , the top plate 101 , the hot air side plate 1010 , the third notch 109 and another first notch 106 form an air guiding channel 2 for guiding hot air.

[0059] In the above structure, the two first slots 106 may only occupy a portion of the front panel 102. Of course, the sum of the areas of the cabinet front door fitting surface 12 of the front panel 102 and the two first slots 106 may be equal to the total area of ​​the corresponding rectangle of the front panel 102. Then, the above structure can reduce the weight to the greatest extent.

[0060] Further, the structure of the fiber tray box 3 is described in detail. Figure 5-Figure 7 ,

[0061] The fiber tray box 3 includes a support plate 300 and a movable box body 301. The movable box body 301 is provided with an optical fiber accommodating space; the support plate 300 is fixed in the placement space 4;

[0062] A guide groove 307 is provided on the support plate 300, and a clamping female part 303 is provided on the support plate 300 at one end of the guide groove 307 away from the cabinet front door fitting surface 12;

[0063] The bottom of the moving box body 301 is provided with a slider 302 slidably connected to the guide groove 307, and the outer side of the moving box body 301 is provided with a clamping sub-component 304 clamped with the clamping female component 303. The clamping female component 303 and the clamping sub-component 304 are respectively a female head of a bead and a male head of a bead.

[0064] The above realizes the stable linear movement of the movable box body 301 in the placement space 4, and after being in place, it is connected by the clamping mother component 303 and the clamping child component 304 to fix its position. The bumping ball realizes the self-locking of the fiber coil box 3.

[0065] Furthermore, after the fiber tray box 3 is inserted into the placement space 4, the fiber tray box 3 contacts the cabinet front door, and the rear end face of the fiber tray box 3 contacts the cabinet, preventing hot air from flowing back to the cold air area, thereby isolating the cold and hot air. Therefore, one side of the movable box body 301 that blocks the installation notch 15 is flush with the cabinet front door fitting surface 12 to ensure the sealing effect.

[0066] Furthermore, the first partition plate 105 and the second partition plate 108 both include a first plate parallel to the guide groove 307, and the first plate is connected to a second plate at a designed angle thereto; it can also be regarded as that the first partition plate 105 and the second partition plate 108 are symmetrically arranged with each other. Such a guide shape allows cold air to enter the left side of the horizontally inserted device and the left side of the guide device from the front door of the cabinet; hot air is discharged from the right side of the horizontally inserted device, part of which is discharged through the air duct on the right side of the cabinet, and part of which is discharged from the front door of the cabinet through the right front of the guide device, thereby realizing the isolation of cold and hot air and avoiding the problem of affecting heat dissipation.

[0067] Further, in order to facilitate the setting and drawing of the optical fiber during the drawing process of the movable box body 301, the following instructions are provided:

[0068] A wire release opening 305 is provided on one side of the movable box body 301 close to the air inlet side surface 13; a fiber winding column 306 is provided in the optical fiber accommodating space; this facilitates the release of the optical fiber.

[0069] The first partition plate 105 is provided with a first wire groove 10500 extending along the moving direction of the movable box body 301; the cold air side plate 104 is provided with a second wire groove 10400; the first wire groove 10500 and the second wire groove 10400 are both connected to the wind guide channel 2 for guiding cold air, so as to facilitate the wiring operation of the optical fiber and block the wind passage. The bottom wall of the wind guide channel 2 for guiding cold air is provided with a fiber inlet fixing block 5 and a fiber outlet fixing block 6; the fiber inlet fixing block 5 and the fiber outlet fixing block 6 are located between the first wire groove 10500 and the second wire groove 10400.

[0070] For the above, please refer to the attached Figure 8 , Fig. 9 and Fig.10 Description, fiber coiling path: To prevent the optical fiber from blocking the air duct, the fiber input and fiber output are placed side by side along the depth direction of the air guide channel 2 and fixed.

[0071] The position of the optical fiber fixing point affects the pulling out and closing of the fiber coil box 3, and in severe cases, it will cause fiber breakage. Determination of the optical fiber fixing point: The position of the optical fiber fixing point must be related to the stroke of the fiber coil box 3. The center of the fiber coil ring when the fiber coil box is closed and fully pulled out is used as the two endpoints to make the median perpendicular line of the fiber coil box stroke, and the optical fiber fixing point is on this median perpendicular line. The tangent length from the optical fiber fixing point to the fiber coil ring when the fiber coil box is closed is equal to the tangent length from the optical fiber fixing point to the fiber coil ring when the fiber coil box is fully pulled out, thereby ensuring that the fiber coil box will not be dragged by the optical fiber during movement. Taking into account the operability of optical fiber bundling, the optical fiber fixing point is determined on the median perpendicular line.

[0072] In some preferred embodiments, a cabinet connection angle 1011 is provided on the rear plate 103. The cabinet connection angle 1011 facilitates the connection between the partition structure 1 and the cabinet.

[0073] refer to Fig.11 , a cabinet comprising:

[0074] A plurality of flow guiding devices with fiber coiling function are arranged at intervals up and down; the distance between the cabinet rear door and the front door is equal to the distance between the cabinet rear door fitting surface 11 and the cabinet front door fitting surface 12 of the flow guiding device with fiber coiling function.

[0075] A transverse insertion device 7 is provided between adjacent flow guiding devices with fiber coiling function, and between the flow guiding device with fiber coiling function and the bottom of the cabinet.

[0076] Therefore, the use of the above-mentioned air guide device cabinet with fiber coiling function can achieve the isolation of cold and hot air, and improve the space utilization, so that the size of the horizontal plug-in equipment can be increased.
