Description

[Technical Field]

[0001] The present invention relates to an exhaust structure for a cabinet that houses electronic devices and electrical equipment that generate heat, such as servers, and more particularly to a door with multiple air deflectors attached to the door, and a cabinet equipped with this door. [Background technology]

[0002] Cabinets that house heat-generating electronic and electrical equipment usually have exhaust windows (openings) on the top or front door of the cabinet to release heated air to the outside. Air heated by the equipment is then expelled upward or forward from the exhaust windows by a fan installed inside the cabinet. An air intake is also installed in the cabinet at a location away from the exhaust windows. Furthermore, when an exhaust window is provided on the front door, the exhaust air is designed to be discharged upward so that the discharged warm air does not enter the cabinet arranged opposite. For example, in Patent Document 1, the entire door is formed with a large opening to serve as an exhaust window, but air direction adjusting fins (air direction plates) are attached to the entire exhaust window to regulate the flow of the released air so that it is not directed toward the cabinet arranged opposite. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2020-205321 Summary of the Invention [Problem to be solved by the invention]

[0004] The technology of Patent Document 1, which uses an airflow direction vane, makes it possible to change the exhaust direction so that the hot air emitted from an opening such as an exhaust window is not directed toward an opposing cabinet. However, because the angle of each airflow direction vane must be adjusted by an operator, it is cumbersome to set all the airflow direction vanes to the same angle, and it is also cumbersome to close unused openings. Furthermore, it is even more cumbersome when different angles need to be set for the lower and upper parts.

[0005] In view of these problems, the present invention aims to provide a door and cabinet with air deflectors that allow the operation of the air deflectors to be performed all at once, and that allow the angle of the upper air deflector and the angle of the lower air deflector to be set to different angles, making it easy to set the direction of air flow to a preferred angle. [Means for solving the problem]

[0006] In order to solve the above problems, the first configuration of the present invention is a door with a wind deflector, which has an opening formed from top to bottom to allow air to pass through, and has multiple wind deflectors arranged in the opening that allow the direction of air flow to be changed in the vertical direction, each wind deflector is a long, horizontal strip, and both left and right ends are supported on vertical frames arranged upright on the left and right of the opening, with a left-right rotation axis, one of the support parts of the wind deflector is provided with a rotation linkage part for rotating the wind deflector, and each rotation linkage part is engaged with an engaging piece of a rotation operating member arranged along one of the vertical frames, and by operating the rotation operating member in a specific manner, the wind deflector is rotated via the rotation linkage part, opening the opening from a closed state to a certain angle to open the opening, and in this case, the rotation linkage part is configured in multiple types so that the angle at which the wind deflector is rotated by operating the rotation operating member differs depending on the wind deflector installation position, and the opening angle of the wind deflector differs at least between the top and bottom of the opening. With this configuration, even if multiple air deflectors for changing the exhaust direction are attached to the opening, the angle of the air deflectors can be changed all at once by operating the rotation operating member, making it easy to change the direction of the intake or exhaust air. Furthermore, because the air deflectors are configured to rotate at different angles at least at the top and bottom of the opening, when the opening on the front of the cabinet is used as an exhaust window, it is possible to set the angle of the air deflectors attached lower to point the exhaust more upward than the air deflectors attached upper. As a result, exhaust air directed toward the front can be reduced, and the released air can be prevented from entering a cabinet installed facing the front.

[0007] Another aspect of the present invention is characterized in that, in the above configuration, the opening is an exhaust window for discharging air from inside the cabinet, and the vertical width of the air deflector varies depending on the type of rotation linkage part provided, and by operating the rotation operating member, it is positioned parallel to the opening and rotates to tilt forward from a state in which the opening is closed, and the width of the air deflector with a small rotation angle and a large angle of elevation after tilting is wider than the width of the air deflector with a large rotation angle and a small angle of elevation after tilting. According to this configuration, the width of the wind direction plate when the rotation angle is set small is larger than the width of the wind direction plate when the rotation angle is set large, so even in a configuration where the air discharge direction is changed significantly due to a small rotation angle, the air discharge direction can be changed well.

[0008] The second configuration of the present invention is a cabinet having an opening on the front or back for discharging air heated by the stored equipment, characterized in that the cabinet has a door with a wind deflector as described in claim 1 or 2 on at least one of the front and back, and has an opening on the front or back for discharging air heated by the stored equipment. With this configuration, if the cabinet is equipped with a fan that forcibly exhausts the air heated by the equipment housed inside, the exhaust direction can be changed with the air deflector. Therefore, even if a cabinet is placed in front of and facing the opening through which the air inside the cabinet is exhausted, the exhaust direction can be adjusted so that the air is not discharged toward the opposing cabinet. [Effects of the Invention]

[0009] According to the present invention, even if multiple airflow direction vanes are attached to an opening to change the direction of the airflow, the angle of the airflow direction vanes can be changed collectively by operating the rotation operating member, making it easy to change the direction of the intake or exhaust air. Furthermore, because the rotation angles of the airflow direction vanes at least at the top and bottom of the opening are configured to be different, when the opening on the front of the cabinet is used as an exhaust window, it is possible to set the angle of the airflow direction vanes attached lower to point the exhaust more upward than the airflow direction vanes attached upper. As a result, exhaust air directed toward the front can be reduced, and the exhausted air can be prevented from entering a cabinet installed facing the front. [Brief explanation of the drawings]

[0011] Hereinafter, embodiments embodying the present invention will be described in detail with reference to the drawings. Figures 1 to 3 show a door with a wind direction plate according to the present invention, with Figure 1 being a perspective view of the door with a wind direction plate with the opening of the door open, Figure 2 being a rear view of the door with a wind direction plate of Figure 1, and Figure 3 being a perspective view of the door with a wind direction plate with the opening closed. Also, Figure 4 is a perspective view of a cabinet equipped with a door with a wind direction plate. The door with air deflector (hereinafter simply referred to as "door") 1 has a rectangular frame body 1a that matches the front opening of the cabinet main body (cabinet) 10, as shown in Figures 1 to 3, and furthermore, a frame-shaped air deflector frame 2 that is slightly smaller than the frame body 1a is arranged inside this frame body 1a and protrudes forward. The inside of this air direction frame 2 is opened widely, forming an opening 3. Here, this opening 3 forms an exhaust window for discharging air from inside the cabinet 10.

[0012] The door 1 has hinges 4 at the top and bottom ends on the right side for attaching to the open front of the cabinet 10 to which it is attached, and a handle 5 at the center of the left side for opening and closing the door. By operating the handle 5, the locking bar 6 located on the back of the door 1 moves up and down, locking / unlocking the upper and lower ends of the door 1 to the cabinet body. By unlocking the door 1, it becomes possible to open and close it freely.

[0013] As shown in Fig. 4, door 1 is attached to the front of cabinet 10, and opening 3 is configured to be used as an exhaust window. Fig. 4 shows the state in which air deflector 11 is closed. An intake window (not shown) is provided on the rear of cabinet 10, and air is drawn in from the rear to cool devices such as electronic devices housed in cabinet 10, and the heated internal air is exhausted from opening 3 of door 1 on the front.

[0014] A plurality of wind direction vanes 11 for changing the flow of exhausted air are attached to the opening 3 of the wind direction frame 2. When all of these wind direction vanes 11 are in an upright position parallel to the opening 3, adjacent wind direction vanes 11 overlap each other, and the opening 3 is closed.

[0015] The shape and operation of the wind direction plate 11 will be specifically described below. Figure 5 is a perspective view illustrating a cross section taken along line AA in Figure 2. As shown in Figure 5, the airflow direction plate 11 has a length that reaches the inner ends of the vertical frames 2a that are arranged upright on the left and right sides of the airflow direction frame 2, and the guide surface 11a that guides the air flow is a strip-shaped piece formed with a constant width (height). At the left and right ends of the wind direction plate 11, pivot support pieces 12 are formed by bending in a direction perpendicular to the guide surface 11a to pivotally support the vertical frame 2a of the wind direction frame 2. Holes 18 forming shafts are formed in the pivot support pieces 12, and rod-shaped support shafts 2c provided on the wind direction frame 2 are inserted into these holes 18 for pivotal support.

[0016] The left and right sides of the air deflector 11 are pivotally supported by the air deflector frame 2 to form a rotation axis, allowing the air deflector 11 to rotate around this rotation axis. The air deflector 11 is attached to the entire air deflector frame 2, and the opening 3 is opened / closed by rotating the air deflector 11.

[0017] Furthermore, one of the pivot support pieces 12 of the wind direction vane 11 is provided with a rotation linkage part 13 for operating the rotation of the wind direction vane 11. The rotation linkage part 13 is formed as a hole with which a rotation operation member 20, which will be described later, engages, and moves up and down by operating the rotation operation member 20, resulting in the wind direction vane 11 rotating. The rotation operation member 20 has a rod-shaped engagement protrusion (engagement piece) 14 that protrudes in the horizontal direction of the wind direction plate 11, that is, in accordance with the position of the support shaft 2c provided on the vertical frame 2a, and is configured to engage with the shaft support piece 12 via the vertical frame 2a. The vertical frame 2a is formed with a vertically long hole 2b through which the engagement protrusion 14 is inserted.

[0018] 6 and 7 are enlarged perspective explanatory views of part B in Fig. 2, showing the state in which the vertical frame 2a constituting part of the air direction frame 2 has been removed to expose the rotation operation member 20. Note that Fig. 6 shows the state in which the opening 3 is open, and Fig. 7 shows the state in which the opening 3 is closed. 6 and 7, the rotation operation member 20 has an engagement protrusion 14 that engages with the pivot support piece 12, which is provided in accordance with the position of the wind direction vane 11, and is inserted into and engaged with the rotation linkage portion 13 of the pivot support piece 12. Due to this engagement, when the rotation operation member 20 is slid up and down along the vertical frame 2a, the pivot support piece 12 rotates, and the wind direction vane 11 that is integrated with the pivot support piece 12 rotates around the support shaft 2c.

[0019] 8 is an enlarged perspective explanatory view of portion C in FIG. 2, and is an explanatory diagram of the operation knob 15 that operates the rotation operation member 20. The operation knob 15 is a bolt-shaped member that is screwed into the rotation operation member 20 through an elongated hole 2d formed in the vertical frame 2a, and its head protrudes toward the rear surface of the door 1 through the vertical frame 2a. The operation knobs 15 are provided in two locations, one above and one below, as shown in FIG. 2. That is, the operation knobs 15 are provided in two locations, one above and one below, on the rear surface of the door 1, and the corresponding vertical frame 2a has a vertically long hole 2d through which the operation knob 15 is inserted to enable vertical movement. By sliding the operation knob 15 up and down, the rotation operation member 20 slides up and down, and the angle of the air direction vane 11 is operated.

[0020] Figure 9 is an explanatory side view of the wind direction vane 11, showing one of the pivot support pieces 12 equipped with the rotation linkage portion 13. Wind direction vanes 11 of different shapes are attached to three locations of the door 1 shown in Figure 2: the upper portion D1, the central portion D2, and the lower portion D3, and the figure shows each of the wind direction vanes 11. Specifically, the shapes of the rotation linkage portion 13 and the width W of the wind direction vanes 11 are different. 9(a) shows the wind direction vane 11 attached to the D1 section, FIG. 9(b) shows the wind direction vane 11 attached to the D2 section, and FIG. 9(c) shows the wind direction vane 11 attached to the D3 section. By changing the shape of the rotation linkage part 13, the rotation angle of the wind direction vane 11, which rotates by operating the rotation operation member 20, can be set to different angles.

[0021] Specifically, the rotation linkage portion 13a (13) of the wind direction vane 11 on the upper portion D1 is a linear elongated hole, and by operating the rotation operation member 20, the engagement protrusion 14 moves through the entire elongated hole, rotating the wind direction vane 11. As a result, the wind direction vane 11 rotates significantly. The rotation linkage portion 13b (13) of the wind direction vane 11 in the center portion D2 is an L-shaped elongated hole with a bent end, and by operating the rotation operation member 20, the engagement protrusion 14 rotates the wind direction vane 11 using only the straight portion of the elongated hole. As a result, the rotation angle is smaller than that of the wind direction vane 11 in the upper portion D1. The rotation linkage portion 13c (13) of the airflow direction vane 11 at the lower portion D3 is a V-shaped elongated hole whose straight portion is shorter than that at the center portion D2, and the straight portion along which the engaging protrusion 14 moves is short. As a result, the rotation angle of the airflow direction vane 11 is smaller than that at the center portion D2. In addition, the maximum rotation angle of each vane 11 from the upright position is 45 degrees (elevation angle 45 degrees) for the upper part D1, 35 degrees (elevation angle 55 degrees) for the central part, and 25 degrees (elevation angle 65 degrees) for the lower part.

[0022] 10 to 12 are explanatory diagrams of the operation of the rotation linkage part 13 of the airflow direction plate 11, with Fig. 10 being an explanatory diagram of the upper part D1, Fig. 11 being an explanatory diagram of the central part D2, and Fig. 12 being an explanatory diagram of the lower part D3. (a) shows the state before rotation in which the opening 3 is closed, and (b) shows the state after rotation in which the opening 3 is opened. As shown in Figures 10 to 12, by sliding the rotation operation member 20 a certain amount, the wind direction vanes 11 are rotated to different angles by the action of the rotation linkage 13. As described above, the wind direction vane 11 in the upper part D1 is tilted (rotated) up to 45 degrees by the rotation linkage 13a consisting of a linear elongated hole. The wind direction vanes 11 in the center part D2 and the lower part rotate a certain amount according to the length of the elongated holes in the rotation linkages 13b and 13c and then stop. As a result, as described above, the wind direction vane 11 in the center part D2 stops after tilting 35 degrees from the upright state, and the wind direction vane 11 in the lower part D3 stops after tilting 25 degrees.

[0023] 9, the width W of the airflow direction vanes 11 varies, with the width W becoming wider as the rotation angle from the upright state becomes smaller. Specifically, the width W1 of the airflow direction vane 11 at the upper portion D1 is, for example, 82 mm, the width W2 of the airflow direction vane 11 at the center portion D2 is, for example, 87 mm, and the width W3 of the airflow direction vane 11 at the lower portion D3 is, for example, 109 mm. In this way, the width W of the lower airflow direction vane 11, which changes the air discharge direction from front to upward more significantly, is wider than that of the upper portion. By widening the width of the air deflector 11, the air discharge direction can be surely changed, and even if the rotation angle is small and the angle of the discharged air is changed significantly from the front direction of the opening 3 as a result, by using the wide air deflector 11, the air can be discharged in the direction matching the orientation of the air deflector 11.

[0024] If the equipment (not shown) housed in cabinet 10 generates heat, it is equipped with a cooling fan, which generates airflow. This airflow is configured to flow in the same direction (from rear to front) within cabinet 10, and the air heated by the equipment is discharged to the outside through opening 3 on the front. The exhaust air generates wind force, which is discharged in the direction set by airflow direction vane 11.

[0025] FIG. 13 is a rear view of the door 1 with the operation knob 15 shown in FIG. 8 further enlarged. As shown in FIG. 13, near the elongated hole 2d in the vertical frame 2a through which the operation knob 15 is inserted, a display is displayed indicating the relationship between the sliding position of the operation knob 15 and the distance to another cabinet 10 located opposite. Here, a scale M of four levels from 0 to 3 is displayed, with scale "0" indicating that the air deflector 11 is closed, scale "1" indicating a distance between the cabinets of 0.8 meters, scale "2" indicating a distance between the cabinets of 0.9 meters, and scale "3" indicating a distance between the cabinets of 1 meter. The optimal angle can be set by adjusting the angle of the air deflector 11 while referring to this scale depending on the installation situation of the cabinets 10. Note that scale 3 is the maximum rotation position, with the wind direction vane 11 at the top D1 rotated 45 degrees, the wind direction vane 11 at the center D2 rotated 35 degrees, and the wind direction vane 11 at the bottom D3 rotated 25 degrees. After setting, by tightening the bolt-shaped operation knob 15, the rotation operation member 20 is fixed in close contact with the vertical frame 2a, and the angle of the wind direction vane 11 is fixed.

[0026] Thus, with the door 1 configured as described above, even if multiple air deflectors 11 for changing the exhaust direction are attached to the opening 3, the angle can be changed all at once by operating the rotation operating member 20, making it easy to change the direction of the intake or exhaust air. Furthermore, because the rotation angles of the air deflectors 11 are configured to be different at least between the upper and lower parts of the opening 3, when the opening 3 provided on the front surface of the cabinet 10 is used as an exhaust window, it is possible to set the angle of the air deflectors 11 attached lower to exhaust air more upward than the air deflectors 11 attached upper. As a result, if cabinet 10 is equipped with a fan that forcibly exhausts air heated by the devices housed therein, the exhaust direction can be changed with air direction plate 11. Therefore, even if a cabinet is placed facing forward of opening 3 that exhausts air from inside cabinet 10, adjustment can be made so that the air is not released toward the cabinet 10 that is placed opposite. Furthermore, since the width W of the wind direction vane 11 when the rotation angle is set small is larger than the width W of the wind direction vane 11 when the rotation angle is set large, the air discharge direction can be changed well even in a configuration in which the air discharge direction is changed significantly due to a small rotation angle.

[0027] In the above embodiment, the door of the cabinet 10 storing electrical equipment is described as a door with a wind deflector 1, but the door with a wind deflector 1 of the present invention can be attached to any standardized box body such as the cabinet 10 or a rack in place of an existing door, and can be used in a wide range of applications. Furthermore, the air deflector 11 is designed to exhaust the warmed air inside the cabinet 10 from the opening 3, and is therefore structured to exhaust air upwards, but contrary to the above configuration, the air deflector 11 may be pivoted to hang down from the air deflector frame 2 and rotated to open the opening 3 downwards, in which case the door 1 can be used for intake air. Furthermore, although the door 1 is attached to the front of the cabinet 10, it may also be attached to the rear. [Explanation of symbols]
