Embodiments for Carrying Out the Invention

[0016] Hereinafter, the support member and the storage box of the embodiment will be described. In the following description, components having the same or similar functions are denoted by the same reference numerals, and redundant descriptions of these components may be omitted. In the present application, "parallel" or "orthogonal" may each include the case of being "substantially parallel" or "substantially orthogonal". In the present application, based on the direction of viewing the rack from a user standing in front of the front of the rack described later, left, right, up, and down are defined. Also, the side closer to the user standing in front of the front of the rack as viewed from the rack is defined as "front", and the far side is defined as "rear". Hereinafter, "front" may be referred to as "in front" and "rear" may be referred to as "rear side". Also, hereinafter, the front-rear direction may be referred to as the "depth direction" and the up-down direction may be referred to as the "vertical direction".

[0017] (Embodiment) <1. Overall Configuration of the Rack> FIG. 1 is a perspective view showing a rack 1 and an electric device 2. The rack 1 is a structure in which the electric device 2 is housed. The rack 1 is installed in a facility such as a communication facility or a data center, for example. The rack 1 is an example of a "storage box".

[0018] The rack 1 houses, for example, a plurality of electric devices 2. The plurality of electric devices 2 are arranged side by side in the vertical direction within the rack 1, for example. The electric device 2 is an information processing device such as an ICT (Information and Communication Technology) device, for example. The ICT device is, for example, a server device, a network device, or a switch device, but is not limited thereto. Also, the electric device 2 housed in the rack 1 is not limited to an information communication device, and may be a power supply device or other electric device.

[0019] As shown in FIG. 1, the rack 1 includes, for example, a housing 10, a main frame structure 20 (see FIG. 2), left and right mounting angles 30A, 30B, and a plurality of blank panels 91 (see FIG. 5).

[0020] <1.1 Housing> The housing 10 is a box member that forms the outer contour of the rack 1. The housing 10 has, for example, a housing body 10a and a front door 10b. The housing body 10a has, for example, a bottom plate 11, a ceiling plate 12, a left side plate 13, a right side plate 14, and a rear plate 15.

[0021] The bottom plate 11 is a plate portion along the horizontal direction and forms the bottom of the housing 10. The ceiling plate 12 is disposed above the bottom plate 11. The ceiling plate 12 is a plate portion along the horizontal direction and forms the ceiling of the housing 10.

[0022] The left side plate 13 extends vertically between the left end portion of the bottom plate 11 and the left end portion of the ceiling plate 12, connecting the left end portion of the bottom plate 11 and the left end portion of the ceiling plate 12. The left side plate 13 is a plate portion along the depth direction and the vertical direction. The right side plate 14 extends vertically between the right end portion of the bottom plate 11 and the right end portion of the ceiling plate 12, connecting the right end portion of the bottom plate 11 and the right end portion of the ceiling plate 12. The right side plate 14 is a plate portion along the depth direction and the vertical direction.

[0023] The rear plate 15 extends vertically between the rear end portion of the bottom plate 11 and the rear end portion of the ceiling plate 12, connecting the rear end portion of the bottom plate 11 and the rear end portion of the ceiling plate 12. The rear plate 15 is a plate portion along the left - right direction and the vertical direction. The rear plate 15 has a plurality of exhaust holes 10hb (see FIG. 3). The exhaust holes 10hb are through - holes penetrating the rear plate 15. Note that the exhaust holes 10hb may be provided on the ceiling plate 12 instead of / in addition to the rear plate 15.

[0024] In the present embodiment, the housing body 10a is formed in a box shape with an opening O provided on the front side. The opening O is larger than the outer shape of the electric device 2 described later, and the electric device 2 can be inserted. The electric device 2 is housed inside the housing 10 through the opening O.

[0025] The front door 10b is formed by a front plate 16 rotatably connected to the housing body 10a. The front plate 16 can open and close the opening O. The front plate 16 has a plurality of intake holes 10ha. The plurality of intake holes 10ha are provided, for example, at most of the height of the front plate 16.

[0026] Note that instead of the rotatable front door 10b, the housing 10 may have a front plate 16 that is detachable from the housing main body 10a. Further, the housing 10 may not have the front door 10b (front plate 16). In this case, the housing 10 may be formed only by the housing main body 10a.

[0027] <1.2 Main Frame Structure> FIG. 2 is a cross-sectional view showing the rack 1. For convenience of explanation, in FIG. 2, the illustration of the screw 82 for attaching the electrical equipment 2 is omitted.

[0028] The main frame structure 20 is a structure composed of rigid members that enhance the strength of the rack 1. The main frame structure 20 is provided, for example, inside the housing 10. The main frame structure 20 has, for example, a left main frame 21A, a right main frame 21B, and an upper main frame 22.

[0029] The left main frame 21A and the right main frame 21B are a pair of support members provided inside the housing 10. The left main frame 21A and the right main frame 21B are arranged on the back side of the opening O and are spaced apart from each other in the left-right direction. Each of the left main frame 21A and the right main frame 21B is an example of a "rigid member". Each of the left main frame 21A and the right main frame 21B has, for example, higher rigidity than the left side plate 13 or the right side plate 14.

[0030] In the present embodiment, the left main frame 21A is arranged at the left front part inside the housing 10 away from the left side plate 13 and extends in the vertical direction (see FIG. 3). The left main frame 21A extends in the vertical direction, for example, over the entire height of the housing 10. On the other hand, the right main frame 21B is arranged at the right front part inside the housing 10 away from the right side plate 14 and extends in the vertical direction (see FIG. 3). The right main frame 21B extends in the vertical direction, for example, over the entire height of the housing 10.

[0031] Instead of the above example, the left main frame 21A and the right main frame 21B may be provided integrally with the housing 10. For example, the left main frame 21A may be provided integrally with the left side plate 13. Also, the right main frame 21B may be provided integrally with the right side plate 14.

[0032] The upper main frame 22 is a beam member provided inside the housing 10. The upper main frame 22 extends horizontally so as to span between the upper end portions of the left main frame 21A and the right main frame 21B, and connects the upper end portions of the left main frame 21A and the right main frame 21B. Instead of the above example, the upper main frame 22 may be provided integrally with the housing 10. For example, the upper main frame 22 may be provided integrally with the ceiling plate 12.

[0033] In addition to the left main frame 21A, the right main frame 21B, and the upper main frame 22 described above, the main frame structure 20 may also have a reinforcing structure similar to or different from the left main frame 21A, the right main frame 21B, and the upper main frame 22 at the rear inside the housing 10.

[0034] <1.3 Mounting Angle> Next, the left and right mounting angles 30A, 30B will be described. The left and right mounting angles 30A, 30B are a pair of members provided inside the housing 10. The left and right mounting angles 30A, 30B are arranged on the back side of the opening O and are spaced apart from each other in the left-right direction. Hereinafter, when the left mounting angle 30A and the right mounting angle 30B are not distinguished, they are simply referred to as "mounting angle 30". The mounting angle 30 is a member on which the electric device 2 can be mounted at an arbitrary height position. The mounting angle 30 is an example of a "support member".

[0035] The left mount angle 30A is fixed to the left main frame 21A. The left mount angle 30A is disposed at the left front portion within the housing 10 and extends in the vertical direction (see FIG. 3). The left mount angle 30A extends vertically, for example, over the entire height of the housing 10. On the other hand, the right mount angle 30B is fixed to the right main frame 21B. The right mount angle 30B is disposed at the right front portion within the housing 10 and extends in the vertical direction (see FIG. 3). The right mount angle 30A extends vertically, for example, over the entire height of the housing 10.

[0036] The mount angle 30 has, for example, a plurality of mounting holes 30h and a plurality of mounting holes 30hs. The plurality of mounting holes 30hs will be described later.

[0037] The plurality of mounting holes 30h are mounting holes for fixing the electric device 2. The plurality of mounting holes 30h are arranged side by side in one direction (for example, the vertical direction) in the mount angle 30. For example, the plurality of mounting holes 30h are arranged at equal intervals in one direction in the mount angle 30. Each mounting hole 30h is a through hole provided in the mount angle 30. Each mounting hole 30h may be a round hole, a square hole, or other shapes. The shape and arrangement interval of each mounting hole 30h comply with, for example, JIS (Japanese Industrial Standards) or EIA (Electronic Industries Alliance) standards.

[0038] A space for accommodating the electric device 2 is formed between the left mount angle 30A and the right mount angle 30B. The electric device 2 is mounted on one or more (for example, two) mounting holes 30h arbitrarily selected from the plurality of mounting holes 30h. In the present application, "mounted on the mounting hole" is not limited to the case of being mounted on the mounting hole itself, and may also include the case of being mounted on a mounting member (such as a cage nut) attached to the mounting hole. The plurality of electric devices 2 are fixed by using the mounting holes 30h and are arranged so as to overlap each other with no substantial gap between two adjacent electric devices 2 in the vertical direction.

[0039] Figure 3 is a cross-sectional view taken along line F3-F3 of the rack 1 shown in Figure 2. Here, for the sake of convenience of explanation, the configuration of the electrical device 2 will be described. The electrical device 2 has, for example, a main body portion 51 and a pair of projecting portions 52A and 52B. The electrical device 2 is housed in the housing 10 through the opening O with the main body portion 51 on the back side and the projecting portions 52A and 52B on the front side.

[0040] The main body portion 51 is formed in a flat rectangular parallelepiped shape. The main body portion 51 includes, for example, a main body case 61 that forms the outer contour of the main body portion 51, various components 62 housed in the main body case 61, and a cooling fan 63 housed in the main body case. The front end portion 51e1 of the main body portion 51 is arranged to face the opening O of the housing 10. The front end portion 51e1 of the main body portion 51 has a plurality of intake holes 2ha. On the other hand, the rear end portion 51e2 of the main body portion 51 is arranged to face the rear plate 15 of the housing 10. The rear end portion 51e2 of the main body portion 51 has a plurality of exhaust holes 2hb.

[0041] When the cooling fan 63 is driven, the air outside the rack 1 moves forward of the electrical device 2 through the intake holes 10ha of the front plate 16 of the housing 10 and flows into the electrical device 2 through the intake holes 2ha of the front end portion 51e1 of the main body portion 51. The air that has flowed into the electrical device 2 absorbs a part of the heat generated by the components 62 included in the electrical device 2 during the process of passing through the inside of the electrical device 2, and is exhausted into the housing 10 through the exhaust holes 2hb of the rear end portion 51e2 of the main body portion 51. The air exhausted into the housing 10 is exhausted to the outside of the housing 10 through the exhaust holes 10hb of the housing 10. Thereby, the heat dissipation of the electrical device 2 is promoted. Note that the electrical device 2 is not limited to a device including the cooling fan 63, and may be a device that releases the heat of the electrical device 2 into the housing 10 by heat dissipation from the surface of the main body portion 51.

[0042] The pair of projecting portions 52A and 52B are attachment portions for attaching the electrical device 2 to the mounting angle 30. The pair of projecting portions 52A and 52B are provided at the front end portion 51e1 of the main body portion 51.

[0043] One protruding portion 52A protrudes leftward, which is one side in the width direction of the main body portion 51, from the left end portion of the front end portion 51e1 of the main body portion 51. The protruding portion 52A is formed in a plate shape along the left-right direction and the vertical direction. The protruding portion 52A has a screw insertion hole 52h for being attached to the left mounting angle 30A (see FIG. 4). The screw insertion hole 52h is a through hole that penetrates the protruding portion 52A in the front-rear direction and faces the mounting hole 30h of the left mounting angle 30A.

[0044] The other protruding portion 52B protrudes rightward, which is the other side in the width direction of the main body portion 51, from the right end portion of the front end portion 51e1 of the main body portion 51. The protruding portion 52B is formed in a plate shape along the left-right direction and the vertical direction. The protruding portion 52B has a screw insertion hole 52h for being attached to the right mounting angle 30B. The screw insertion hole 52h is a through hole that penetrates the protruding portion 52B in the front-rear direction and faces the mounting hole 30h of the right mounting angle 30B.

[0045] Viewed from another perspective, in the present embodiment, the electric device 2 has a case 71 with an open front side and a front panel 72 attached to the front side of the case 71. The dimension W2 in the width direction of the front panel 72 is larger than the dimension W1 in the width direction of the case 71. For this reason, a part of the front panel 72 protrudes leftward from the left side surface of the case 71 and forms the above-described protruding portion 52A. Also, another part of the front panel 72 protrudes rightward from the right side surface of the case 71 and forms the above-described protruding portion 72B.

[0046] Note that the electric device 2 is not limited to a device having a front panel 72. For example, the electric device 2 may have a case 71 and protruding portions 52A and 52B formed by bending a part of the case 71, and the inside of the case 71 may be exposed forward.

[0047] Next, the mounting angles 30A and 30B will be described in detail. FIG. 4 is a cross-sectional view showing an enlarged periphery of the mounting angles 30A and 30B. First, the left mount angle 30A will be described. The left mount angle 30A has, for example, a fixing portion 35 and a supporting portion 36.

[0048] The fixing portion 35 is a portion for fixing the left mount angle 30A to the left main frame 21A. The fixing portion 35 is plate-shaped along the depth direction and the vertical direction. The fixing portion 35 extends vertically so as to span the entire height of the mount angle 30. The fixing portion 35 has a screw insertion hole 35h penetrating it in the left-right direction. The left main frame 21A has a screw hole 21h communicating with the screw insertion hole 35h of the fixing portion 35. By engaging a screw 81 passed through the screw insertion hole 35h of the fixing portion 35 with the screw hole 21h of the left main frame 21A, the fixing portion 35 is fixed to the right side surface of the left main frame 21A.

[0049] The supporting portion 36 has, for example, a first portion 41, a second portion 42, and a third portion 43. The first portion 41 bends from the front end portion of the fixing portion 35 and extends rightward. That is, the first portion 41 extends from the front end portion of the fixing portion 35 toward the main body portion 51 of the electric device 2. The first portion 41 is plate-shaped along the left-right direction and the vertical direction. The first portion 41 extends vertically so as to span the entire height of the mount angle 30. The mounting holes 30h and 30hs are not provided in the first portion 41. That is, no opening is provided in the first portion 41.

[0050] The second part 42 bends (e.g., bends 90°) from the right end of the first part 41 and extends forward. That is, the second part 42 extends from the right end of the first part 41 toward the opening O of the housing 10. The second part 42 is plate-shaped along the depth direction and the vertical direction. The second part 42 extends vertically over the entire height of the mount angle 30. The second part 42 is along the left side surface of the main body 51 of the electric device 2. In this embodiment, the gap between the second part 42 and the main body 51 of the electric device 2 is small, for example, substantially zero. For example, the gap between the second part 42 and the main body 51 of the electric device 2 is smaller than the plate thickness t of the second part 42. The second part 42 is not provided with the mounting holes 30h and the mounting holes 30hs. That is, the second part 42 is not provided with an opening.

[0051] The third part 43 bends (e.g., bends 90°) from the front end of the second part 42 and extends leftward. That is, the third part 43 extends from the front end of the second part 42 in a direction away from the main body 51 of the electric device 2. The third part 43 is plate-shaped along the left-right direction and the vertical direction. The third part 43 is, for example, parallel to the first part 41. The third part 43 extends vertically over the entire height of the mount angle 30. The third part 43 faces the opening side of the housing 10. In a state where the electric device 2 is mounted on the mount angle 30, the third part 43 is along the rear surface (back surface) of the overhanging part 52A of the electric device 2. A plurality of mounting holes 30h and a plurality of mounting holes 30hs are provided in the third part 43 (see FIG. 2).

[0052] The overhanging portion 52A of the electric device 2 is attached to the third portion 43. For example, a mounting member 85 is attached to the mounting hole 30h of the third portion 43 from the rear surface side of the third portion 43. The mounting member 85 is, for example, a cage nut. The mounting member 85 includes an engaging portion 85a that is inserted into the mounting hole 30h and engages with the mounting hole 30h, and a threaded hole 85h that opens forward of the third portion 43. The electric device 2 is arranged such that the screw insertion hole 52h of the overhanging portion 52A aligns with the threaded hole 85h of the mounting member 85. A screw 82 is inserted through the screw insertion hole 52h of the overhanging portion 52A from the front of the third portion 43, and the screw 82 engages with the threaded hole 85h of the mounting member 85, thereby attaching the electric device 2 to the third portion 43 of the support portion 36. Thus, the overhanging portion 52A of the electric device 2 is attached to one or more (for example, two) mounting holes 30h arbitrarily selected from the plurality of mounting holes 30h.

[0053] Note that, instead of the above example, the mounting hole 30h may be a threaded hole with which the screw 82 directly engages, or may be a screw insertion hole through which the screw 82 passes. The "mounting hole" as used in this application may be any hole used for fixing the electric device 2.

[0054] As shown in FIG. 4, the space S between the first portion 41 and the third portion 43 (the space S located behind the third portion 43) communicates with the opening O only through the region (the first region S1 described later) located closer to the opening O side than the first portion 41 within the housing 10. The space S located behind the third portion 43 is not connected to the second region S2 described later. In other words, the spaces before and after the mounting hole 30h are integral with the space on the front surface side of the mount angle 30A.

[0055] Next, the right mount angle 30B will be described. Note that the right mount angle 30B has a shape that is symmetric to the left mount angle 30A with respect to left and right. Therefore, for the description of the right mount angle 30B, in the above description regarding the left mount angle 30A, simply read it with the left and right reversed, read "left mount angle 30A" as "right mount angle 30B", and read "overhanging portion 52A" as "overhanging portion 52B".

[0056] In addition to the above-described left and right mounting angles 30A and 30B, another mounting angle for supporting the rear end portion of the electric device 2 may be provided inside the housing 10, and a support angle for supporting the side end portion of the electric device 2 may also be provided.

[0057] Next, a plurality of regions (first region S1 and second region S2) formed inside the housing 10 by the electric device 2 and the left and right mounting angles 30A and 30B will be described.

[0058] The first region (first space) S1 is a cold air region where cold air flows in from the outside through the opening O of the housing 10. In the present application, "cold air" means air before being heated by the electric device 2, for example, air at room temperature. The first region S1 is defined by, for example, the front surface of the left main frame 21A, the front surface of the first portion 41 of the left mounting angle 30A, the left side surface of the second portion 42 of the left mounting angle 30A, the front surface of the electric device 2, the front surface of the right main frame 21B, the front surface of the first portion 41 of the right mounting angle 30B, and the right side surface of the second portion 42 of the right mounting angle 30B. The first region S1 is the region in the housing 10 that is not hatched with dots in FIGS. 3 and 4. A plurality of intake holes 2ha of the electric device 2 open into the first region S1. Cold air flows into the interior of the electric device 2 from the first region S1 through the plurality of intake holes 2ha.

[0059] On the other hand, the second region (second space) S2 is a heated region where the air heated by the electric device 2 is located. The second region S2 is, for example, a region behind the first portions 41 of the left and right mounting angles 30A and 30B. Here, in the present embodiment, the gap between the second portions 42 of the left and right mounting angles 30A and 30B and the left and right side surfaces of the main body portion 51 of the electric device 2 is negligibly small (for example, smaller than the plate thickness t of the second portion 42). In this case, the second region S2 is defined by the rear surfaces of the first portions 41 of the left and right mounting angles 30A and 30B and the left and right side surfaces of the main body portion 51 of the electric device 2. Note that when the gap between the second portions 42 of the left and right mounting angles 30A and 30B and the left and right side surfaces of the main body portion 51 of the electric device 2 is large, the second region S2 may include the regions of the second portions 42 of the left and right mounting angles 30A and 30B and the left and right side surfaces of the main body portion 51 of the electric device 2. The second region S2 is the region hatched with dots within the housing 10 in FIGS. 3 and 4. The plurality of exhaust holes 2hb of the electric device 2 open into the second region S2. The air heated by passing through the inside of the electric device 2 is exhausted from the plurality of exhaust holes 2hb of the electric device 2 into the second region S2.

[0060] <1.4 Blank Panel> Next, the blank panel 91 will be described. FIG. 5 is a cross-sectional view showing the rack 1 and the electric device 2 with the blank panel 91 attached. In FIG. 5, for convenience of explanation, the illustration of the screws 82 for attaching the electric device 2 and the blank panel 91 is omitted.

[0061] The blank panel 91 is a member that assists in partitioning the inside of the housing 10 into a first region S1 and a second region S2, and is disposed in the height region of the non-mounted portion of the electric device 2. The blank panel 91 has screw insertion holes 91h similar to the screw insertion holes 52h of the electric device 2, and in the height region of the non-mounted portion of the electric device 2, it is attached to the left and right mounting angles 30A and 30B by screws 82 in the same manner as the electric device 2. Thereby, a wall portion that partitions the first region S1 and the second region S2 is formed in the height region of the non-mounted portion of the electric device 2. As a result, the return of the warm air in the second region S2 to the first region S1 through the height region of the non-mounted portion of the electric device 2 is suppressed.

[0062] By the way, some blank panels 91 have a shape that does not cover some of the mounting holes 30h. Hereinafter, an example of such a blank panel 91 will be described.

[0063] FIG. 6 is a perspective view showing an example of the blank panel 91. The blank panel 91 shown in FIG. 6 has an opening 91a in a portion corresponding to some of the mounting holes 30h. The opening 91a is provided so that, for example, when the blank panel 91 alone lacks rigidity, a reinforcing panel 92 can be additionally attached to the mounting angles 30A and 30B so as to overlap the blank panel 91. The reinforcing panel 92 has screw insertion holes 92h similar to the screw insertion holes 52h of the electric device 2. The screw insertion holes 92h face the mounting holes 30h of the mounting angles 30A and 30B through the opening 91a of the blank panel 91. The reinforcing panel 92 is attached to the left and right mounting angles 30A and 30B by screws 82 in the same manner as the electric device 2. However, the reason why the blank panel 91 has a shape that does not cover some of the mounting holes 30h is not limited to the above example, and may be another reason.

[0064] When such a blank panel 91 that does not cover some of the mounting holes 30h is attached to the mounting angles 30A and 30B (for example, when there is no problem with rigidity only with the blank panel 91 and the reinforcing panel 92 is omitted), some of the mounting holes 30h are not blocked in the state where the electric device 2 is attached to the mounting angles 30A and 30B, and these mounting holes 30h remain in a state where air can pass through. The phenomenon that occurs in this case will be described later.

[0065] <1.5 Side blank panel> Next, the side blank panel 95 will be described. As shown in FIG. 4, the third portion 43 of the support portion 36 of the mounting angle 30 has a plurality of mounting holes 30hs (only one is shown in FIG. 4). In the left mounting angle 30A, the mounting holes 30hs are arranged to the left of the mounting hole 30h. In the right mounting angle 30B, the mounting holes 30hs are arranged to the right of the mounting hole 30h.

[0066] As shown in FIG. 2, the plurality of mounting holes 30hs are arranged side by side in the vertical direction. The side blank panel 95 is attached to the plurality of mounting holes 30hs by, for example, screws (not shown). The side blank panel 95 is a panel arranged on the side of the electric device 2 and on the side of the blank panel 91 in order to further suppress the air heated by the electric device 2 from returning to the front side of the electric device 2. For example, the side blank panel 95 is arranged between the electric device 2 and the left side plate 13 and between the electric device 2 and the right side plate 14 (see FIG. 3). Similarly, the side blank panel 95 is arranged between the blank panel 91 and the left side plate 13 and between the blank panel 91 and the right side plate 14. Note that the side blank panel 95 may be omitted.

[0067] <1.6 Ventilation restricting member> Next, the ventilation restricting member M will be described. The rack 1 has a ventilation restricting member M that restricts the movement of air from the second region S2 to the first region S1 within the rack 1. The ventilation restricting member M is disposed, for example, between the left main frame 21A and the left side plate 13, or between the right main frame 21B and the right side plate 14, and extends in the vertical direction. When there are gaps between the left main frame 21A and the left side plate 13 and between the right main frame 21B and the right side plate 14 respectively, the ventilation restricting member M closes those gaps. In other words, the ventilation restricting member M is a member that forms part of a partition separating the first region S1 and the second region S2. When the ventilation restricting member M is provided, the movement of the warm air in the second region S2 to the space behind the third portion 43 of the support portion 36 of the mount angles 30A, 30B is suppressed. In the present embodiment, when the ventilation restricting member M is provided, the side blank panel 95 is omitted.

[0068] <2. Operation> FIG. 7 is a diagram for explaining the operation of the left and right mount angles 30 of the present embodiment. (a) in FIG. 7 shows an L-shaped mount angle 100 as a comparative example. (b) in FIG. 7 shows the mount angles 30A, 30B of the present embodiment.

[0069] The L-shaped mount angle 100 of the comparative example shown in (a) in FIG. 7 has a first portion 101 that extends forward from a fixing portion 35 fixed to the left and right main frames 21A, 21B, and a second portion 102 that is bent from the front end portion of the first portion 101. The second portion 102 has screw insertion holes 30h, and the overhanging portions 52A, 52B of the electric device 2 are attached thereto.

[0070] In this configuration, the space located behind the second portion 102 where the screw insertion hole 30h opens becomes part of the second region S2, and there is air warmed by the electrical device 2. In this configuration, when a blank panel 91 that does not cover some of the mounting holes 30h of the mount angle 100 is attached, warm air in the second region S2 leaks into the first region S1 through the mounting holes 30h of the mount angle 100 that are not covered by the blank panel 91. As a result, the cold air in the first region S1 is warmed, and there is a possibility that the warm air flows into the interior of the electrical device 2 from the intake hole 2ha of the electrical device 2. In this case, it becomes difficult to promote the cooling of the electrical device 2.

[0071] Also, when mounting holes 30hs are provided in the second portion 102 of the mount angle 100, even when the ventilation restricting member M is attached, warm air in the second region S2 leaks into the first region S1 through the mounting holes 30hs. From this perspective as well, it becomes difficult to promote the cooling of the electrical device 2.

[0072] On the other hand, as shown in (b) of FIG. 7, in the mount angle 30 of the present embodiment, the space S located behind the third portion 43 where the mounting hole 30h opens becomes part of the first region S1, and there is cold air. Therefore, even when a blank panel 91 that does not cover some of the mounting holes 30h of the mount angles 30A and 30B is attached, leakage of warm air in the second region S2 into the first region S1 through the mounting holes 30h of the mount angles 30A and 30B that are not covered by the blank panel 91 is suppressed. As a result, compared with the configuration of the above comparative example, cold air easily flows into the interior of the electrical device 2 from the intake hole 2ha of the electrical device 2. For this reason, the cooling of the electrical device 2 is promoted.

[0073] Also, even when mounting holes 30hs are provided in the third portion 43 of the mount angle 30, if the ventilation restricting member M is provided, leakage of warm air in the second region S2 into the first region S1 through the mounting holes 30hs is suppressed. From this perspective as well, the cooling of the electrical device 2 is promoted.

[0074] <3. Advantages> In this embodiment, the mounting angle 30 includes a fixing portion 35 fixed to the left main frame 21A (or the right main frame 21B), and a plurality of mounting holes 30h arranged side by side in one direction, and an overhanging portion 52A (or overhanging portion 52B) of the electric device 2 can be mounted on one or more mounting holes 30h arbitrarily selected from the plurality of mounting holes 30h. The support portion 36 includes a first portion 41 extending from the fixing portion 35 toward the main body portion 51 of the electric device 2, a second portion 42 bent from the end of the first portion 41 and extending toward the opening O, and a third portion 43 bent from the end of the second portion 42 and extending in a direction away from the main body portion 51 of the electric device 2, provided with a plurality of mounting holes 30h, and the overhanging portion 52A (or overhanging portion 52B) of the electric device 2 is mounted thereon. According to such a configuration, even when there are mounting holes 30h of the mounting angles 30A and 30B not covered by the blank panel 91, it is possible to suppress the warm air in the second region S2 from leaking to the front side of the electric device 2 through the mounting holes 30h. Thereby, the cooling of the electric device 2 can be promoted, and the cooling performance of the electric device 2 can be improved.

[0075] In this embodiment, the second portion 42 of the support portion 36 is along the side surface of the main body portion 51 of the electric device 2. According to such a configuration, when the electric device 2 is inserted into the housing 10, the second portion 42 of the support portion 36 can be used as a guide for guiding the electric device 2 in the depth direction of the housing 10. Thereby, the workability of attaching the electric device 2 can be improved.

[0076] In this embodiment, the third portion 43 of the support portion 36 is along the rear surface of the overhanging portion 52A (or overhanging portion 52B) of the electric device 2. According to such a configuration, the gap between the third portion 43 of the support portion 36 and the overhanging portion 52A (or overhanging portion 52B) of the electric device 2 can be made small (for example, zero). Thereby, it is possible to further suppress the warm air in the second region S2 from leaking to the front side of the electric device 2.

[0077] In this embodiment, the third portion 43 of the support portion 36 is exposed on the opening O side of the housing 10. According to such a configuration, a configuration for suppressing the leakage of the warm air in the second region S2 to the front side of the electric device 2 is realized, and the workability of attaching the electric device 2 to the mounting angle 30 can be improved.

[0078] As described above, the support member and the storage box of one embodiment have been described. However, the configuration of the embodiment is not limited to the above example. The "storage box" referred to in this application is not limited to a rack in which the electric devices 2 are arranged vertically stacked, and may be a storage box in which the electric devices 2 are horizontally arranged side by side (that is, a storage box in which the mounting holes are horizontally arranged side by side).
