Description

[Technical Field]

[0001] The present invention relates to a storage box for electrical and electronic equipment. [Background technology]

[0002] Electrical and electronic equipment storage boxes are used as racks for mounting electrical and electronic equipment units such as servers, storage devices, network devices, and UPSs. Heat generated by the electrical and electronic equipment mounted in the housing of the electrical and electronic equipment storage box can increase the temperature inside the housing, potentially shortening the lifespan of the mounted electrical and electronic equipment. For this reason, a cooling device using a refrigerant, compressor, evaporator, etc. for cooling the inside of the housing is mounted in the electrical and electronic equipment storage box, providing cooling. The technology disclosed in Patent Document 1 routes wiring from outside the housing and wiring for the electrical and electronic equipment units through a space separate from the housing.

[0004] However, in the above-mentioned document, the exhaust hood is attached to the outside of the housing of the electrical and electronic equipment storage box, and the routing of the wiring inside the housing is not taken into consideration. Furthermore, the cooling device is conceived as a small device attached to the rear surface of the housing. However, in order to improve the cooling performance of the electrical and electronic equipment storage box, it is also possible to enlarge the cooling device. Furthermore, an increase in size may result in an increase in weight. In this case, it is preferable to position the cooling device near the bottom of the housing. Meanwhile, it is preferable to introduce the electric wires that transmit electricity into the housing from near the bottom of the housing.

[0007] Furthermore, it is preferable that the duct portion has a narrowing portion at at least one of the front and rear ends, where the width of the inside left and right gradually decreases, and that the narrowing portion has an inclined surface that gradually shortens the distance between the right and left surfaces toward the end of the duct portion, and that the configuration has a wiring space surrounded by the side of the housing, the inclined surface of the duct portion, and the housing panel.

[0008] Furthermore, it is preferable that the cooling device be configured so that the exhaust port of the duct section is biased to one of the left and right sides of the duct section, a ventilation fan and a heating element are provided inside the duct, the ventilation fan is biased to one of the left and right sides of the duct section so as to face the exhaust port, and at least a portion of the heating element overlaps with the inclined surface when viewed in the front-to-back direction.

[0009] It is also preferable to provide a housing panel with ventilation holes on the surface facing the intake or exhaust port of the duct section, and a wiring panel through which electric wires can be passed is provided next to the housing panel with ventilation holes.

[0012] An embodiment of the invention is described below. The electrical and electronic equipment storage box EB of the embodiment is a rack capable of mounting electrical and electronic equipment units 91 such as a panel unit, server, storage, network equipment, and uninterruptible power supply (UPS) inside a housing 2. This electrical and electronic equipment storage box EB is installed inside a building such as a data center.

[0013] In the electrical and electronic equipment storage box EB of this embodiment, the internal space of the housing 2 is divided into upper and lower sections by a dividing plate 21. Above this dividing plate 21 is provided a unit storage space 20a in which electrical and electronic equipment used for the main purpose of the electrical and electronic equipment storage box EB is stored. Also, below this dividing plate 21 is provided a cooling device storage space 20b in which a cooling device 5 used to cool the unit storage space 20a is stored (see FIGS. 1 and 2).

[0014] In the electric / electronic device storage box EB of the embodiment, a mounting angle 22 on which an electric / electronic device unit 91 can be mounted is provided inside the housing 2. The mounting angle 22 is arranged to extend vertically in the unit storage space 20a, and multiple electric / electronic device units 91 can be fixed in a vertically aligned arrangement (see FIG. 3).

[0015] In this embodiment, a partition 41, which is used to prevent cold air and warm air from mixing in the unit storage space 20a, is attached to the mounting angle 22 so as to fill the gap between the side panel 25 and the mounting angle 22. The partition 41 has multiple wire-passing holes 411, which are arranged at predetermined intervals. Covering the wire-passing holes 411 with an elastically deformable rubber plate or a brush-like blank sheet allows electric wires to pass through the partition 41 while preventing air from passing through the partition 41.

[0016] 1 to 3, an openable / closable door 23 is provided on the front side of the electrical / electronic device storage box EB, and this door 23 corresponds to the unit storage space 20a, and the vertical length of door 23 corresponds to the vertical length of unit storage space 20a. In addition, a front panel 24, which is a housing panel having an air intake hole 241, is provided below door 23. This front panel 24 corresponds to the cooling device storage space 20b, and the vertical length of front panel 24 corresponds to the vertical length of cooling device storage space 20b.

[0017] Therefore, by opening the door 23, it is possible to access the unit storage space 20a, but it is not possible to access the cooling device storage space 20b unless the front panel 24 is opened (see FIG. 3). Similarly, by opening the front panel 24, it is possible to access the cooling device storage space 20b, but it is not possible to access the unit storage space 20a unless the door 23 is opened. In this embodiment, the door 23 is rotatable, and the front panel 24 and a rear panel 27, which will be described later, are fixed with screws. Furthermore, the door 23 in this embodiment is provided with a window portion 231 that is used to view the unit storage space 20a from the outside.

[0018] 1 is configured to expose a display unit 59 that can display the operating status of the cooling device 5. The front panel 24 may also be configured to expose an operation unit that can turn the cooling device 5 on and off.

[0019] The housing 2 is also provided with a wiring lead-in / out section 11 that allows the electric wires and the like (electric wires and communication lines) of the electric / electronic device unit 91 to pass in and out of the housing 2. As shown in Fig. 1, the wiring lead-in / out section 11 can be provided in the upper part of the electric / electronic device storage box EB so that the electric wires and the like can pass in and out from the top surface of the housing 2, but as will be described later, it is also possible to provide the wiring lead-in / out section 11 in the lower part of the electric / electronic device storage box EB.

[0020] The housing 2 of this embodiment has a skeleton formed by a vertical frame 31, a horizontal frame 32, and a depth frame 33. Side panels 25 are attached to the left and right sides of the skeleton so as to cover the left and right sides of the skeleton. The side panels 25 of this embodiment have vertical lengths set to correspond to the combined height of the unit storage space 20a and the cooling device storage space 20b. However, the side panels 25 may also be formed by combining multiple parts. For example, the side panels 25 may be formed by arranging parts in the front-to-back direction, or by arranging parts in the up-to-down direction. Of course, a configuration that combines these may also be used.

[0021] In the example shown in Fig. 1, a ceiling plate 26 is attached so as to cover the top of the framework. Meanwhile, a bottom plate 29 is attached so as to cover the bottom of the framework. The front side of the framework is configured so as to be able to be covered with a door 23 and a front panel 24. Furthermore, the rear side of the framework is configured so as to be able to be covered with a back plate, a rear panel 27, and a wiring panel 28. The back plate may be replaced with a door body.

[0022] A rear panel provided on the rear side of the electrical / electronic device storage box EB corresponds to the unit storage space 20a, and the vertical length of the rear panel corresponds to the vertical length of the unit storage space 20a. In addition, a rear panel 27, which is a housing panel having an exhaust hole 271, is provided below the door 23. This rear panel 27 corresponds to the cooling device storage space 20b, and the vertical length of the rear panel 27 corresponds to the vertical length of the cooling device storage space 20b.

[0023] The housing 2 of this embodiment is provided with a pair of guide rails 42 along the bottom plate 29. These guide rails 42 are used to move the cooling device 5. Specifically, the cooling device 5 can be taken in and out by moving it in the front-to-rear direction along the guide rails 42 provided on the housing 2 (see FIGS. 2 and 4).

[0024] The cooling device 5 of the embodiment is provided with an intake hole 51 used to take in air into the cooling device 5 and an exhaust hole 52 used to exhaust air from the cooling device 5. In the embodiment, the intake hole 51 and the exhaust hole 52 are arranged on the top surface of the cooling device 5 so as to face the unit storage space 20a. The electrical and electronic equipment storage box EB takes in air heated in the unit storage space 20a into the cooling device 5 through the intake hole 51, cools this air inside the cooling device 5, and then returns the air to the unit storage space 20a located outside the cooling device 5 through the exhaust hole 52.

[0025] In order to lower the temperature of the unit housing space 20a using the cooling device 5 arranged in the cooling device housing space 20b, the unit housing space 20a and the cooling device housing space 20b are partially connected via the communication space 20c. To make this possible, in this embodiment, the area of ​​the dividing plate portion 21 in a plan view is configured to be smaller than the area of ​​the housing 2 in a plan view. In this embodiment, the vertical length of the communication space 20c is approximately the same as the vertical length of the dividing plate portion 21.

[0026] In the example shown in FIG. 2, the dividing plate 21 forms an opening on the front end side of the housing 2, forming a communication space 20c. This is to allow air to move between the unit storage space 20a and the cooling device storage space 20b at the front side of the housing 2. On the other hand, although not shown in FIG. 2, the dividing plate 21 extends to the rear end, preventing air from moving between the unit storage space 20a and the cooling device storage space 20b at the rear side of the housing 2. Note that the intake holes 51 and exhaust holes 52 of the cooling device 5 of the embodiment are arranged to overlap with the communication space 20c in a plan view. Alternatively, the communication space 20c may be formed by a configuration in which the dividing plate 21 does not extend to the front end of the housing.

[0027] 5, the exhaust hole 52 is located in front of the intake hole 51. More specifically, the cooling air is sent to the left and right of the housing 2 in front of the partitions 41 extending in the vertical direction, and the air is drawn into the cooling device 5 behind the partitions 41.

[0028] For this reason, air sent forward from the partition 41 can move to the rear side of the partition 41 through the electric / electronic device unit 91. In other words, the electric / electronic device unit 91 has a vent port in front of the partition 41, and also has a vent port behind the partition 41. Note that the electric / electronic device unit 91 does not necessarily have to be of this type, but in order to efficiently cool the electric / electronic device unit 91 with the air sent forward from the partition 41, it is preferable that the electric / electronic device unit 91 have the above-mentioned vent port.

[0029] In this embodiment, an intake and exhaust unit used to restrict the air path is disposed directly above the intake holes 51 and exhaust holes 52 of the cooling device 5. The intake and exhaust unit of this embodiment includes an intake and exhaust panel 61 that can cover both the intake holes 51 and the exhaust holes 52 (see FIG. 6). The intake and exhaust panel 61 of this embodiment includes holes corresponding to the intake holes 51 and the exhaust holes 52 of the cooling device 5.

[0030] The intake and exhaust panel 61 may be made up of a single plate, or may be made up of a combination of multiple plates. For example, the intake and exhaust panel 61 may be made up of a combination of a plate material that will become the intake panel portion 611 and a plate material that will become the exhaust panel portion 612. The intake and exhaust panel portion 611 and the exhaust panel portion 612 may be connected by welding or by using screws or the like. The intake and exhaust panel portion 611 and the exhaust panel portion 612 may also be configured to be spaced apart.

[0031] In addition, in order to reduce the effort required for installation or removal work, it is preferable that the intake and exhaust panel 61 comprises an intake panel portion 611 having a hole corresponding to the intake hole portion 51 of the cooling device 5, and an exhaust panel portion 612 having a hole corresponding to the exhaust hole portion 52, and that the intake panel portion 611 and the exhaust panel portion 612 are configured as one unit.

[0032] The intake and exhaust unit of this embodiment also includes a partition member 62 that extends in the vertical direction above the intake and exhaust panel 61 (see FIG. 7). This partition member 62 is arranged so as to be located between the intake hole and the exhaust hole of the intake and exhaust panel 61 in a plan view. This arrangement makes it possible to prevent the intake air and the exhaust air from crossing directly above the intake and exhaust panel 61. The intake and exhaust unit of this embodiment also includes louvers 63 that are used to adjust the direction of the air coming out of the exhaust hole of the intake and exhaust panel 61 (see FIG. 8).

[0033] In this embodiment, a cover 64 is disposed across the dividing plate 21 and the intake / exhaust panel 61 to guide the air on the dividing plate 21 toward the intake holes of the intake / exhaust panel 61 (see FIG. 9). The cover 64 is configured to ensure an air passage between the cover 64 and the dividing plate 21, and also to ensure an air passage between the cover 64 and the intake panel 611 (see FIG. 10). To enable this, the cover 64 shown in FIG. 8 is configured from a plate material with a U-shaped cross section. In this embodiment, the intake / exhaust unit is the intake / exhaust panel 61, the partition member 62, and the louver 63 (see FIGS. 11 and 12), but the components of the intake / exhaust unit and the cover 64 can be attached from above the dividing plate 21.

[0034] Here, an example of installing the intake and exhaust panel 61 and the like will be described. To fit the cooling device 5 into the cooling device storage space 20b, the cooling device 5 is moved to a predetermined position along the guide rails 42. After the cooling device 5 reaches the predetermined position and is secured in place, the front panel 24 is installed. In this embodiment, the intake holes 51 and exhaust holes 52 of the cooling device 5 when placed in the predetermined position do not overlap with the partition plate 21 in a plan view, but overlap with the communication space 20c interposed between the unit storage space 20a and the cooling device storage space 20b in a plan view. In addition, at this time, the intake holes 51 of the cooling device 5 are located rearward of the mounting angle 22, and the exhaust holes 52 are located forward of the mounting angle 22.

[0035] Once the cooling device 5 has been placed in a predetermined position within the housing 2, the intake / exhaust panel 61 is dropped from the unit storage space 20a side through the communication space 20c toward the cooling device 5 (see FIGS. 13 and 14). At this time, the intake / exhaust panel 61 and the cooling device 5 are brought into contact with each other so as to prevent air from passing between the intake hole 51 and the exhaust hole 52 through the gap between the intake / exhaust panel 61 and the cooling device 5. In this way, it is possible to prevent air cooled by the cooling device 5 from moving along the top of the cooling device 5 and being immediately sucked into the cooling device 5.

[0036] As can be understood from these descriptions, the box EB for storing electrical and electronic equipment has, inside the housing 2, a partition plate portion 21, a unit storage space 20a located above the partition plate portion 21, and a cooling device storage space 20b located below the partition plate portion 21, and is provided with an intake and exhaust panel 61 having a plate-shaped portion, and is provided with an intake hole portion 51 used to draw air into the unit storage space 20a to the cooling device 5 that is slid to a predetermined position in the cooling device storage space 20b, and an exhaust hole portion 52 used to exhaust the air drawn in from the intake hole portion 51 into the unit storage space 20a after cooling, and it is preferable that the intake and exhaust panel 61 be configured so that it can contact the cooling device 5 at a position between the intake hole portion 51 and the exhaust hole portion 52 in a planar view when positioned so as to face the intake hole portion 51 and the exhaust hole portion 52 of the cooling device 5 from the unit storage space 20a side through the communication space 20c interposed between the unit storage space 20a and the cooling device storage space 20b.

[0037] In this way, in the electrical / electronic device storage box EB, which has inside the housing 2 a space above the dividing plate 21 for mounting the electrical / electronic device unit 91 and a space below the dividing plate 21 for storing the cooling device 5 that cools the electrical / electronic device unit 91, it is possible to make it easy to put in and take out the cooling device 5 and to prevent a decrease in the performance of the cooling device 5. Furthermore, even if the intake hole 51 and the exhaust hole 52 are not spaced apart, it is possible to prevent air coming out of the exhaust hole 52 from reaching the intake hole 51 via the cooling device 5. Note that if the cooling device storage space 20b is made large enough to allow the cooling device 5 to slide just as far as possible, it is also possible to prevent the size of the unit storage space 20a inside the housing 2 from becoming smaller.

[0038] In this embodiment, the partition member 62, which is positioned to extend upward from a position between the intake hole 51 and the exhaust hole 52 in a plan view, is positioned to contact the intake / exhaust panel 61, which is in contact with the top surface of the cooling device 5, and is fixed to the mounting angle 22. Fixing the partition member 62 prevents the intake / exhaust panel 61 from moving upward, and as a result, the intake / exhaust panel 61 is also fixed to the cooling device 5. This eliminates the need for a member to fix only the intake / exhaust panel 61, making it possible to reduce the number of parts. Note that in this embodiment, the mounting angle 22 and the partition member 62 are fixed together with the partition member 62 in contact with the front side of the mounting angle 22. This makes it easier to fix the partition member 62.

[0039] As can be understood from these descriptions, it is preferable to have a partition member 62 that is attached so as to span between the mounting angles 22 in the unit storage space 20a, and when the partition member 62 is fixed to the mounting angle 22 while abutting against the upper surface of the intake and exhaust panel 61, the partition member 62 can be positioned so that it extends upward from a position that is between the intake hole portion 51 and the exhaust hole portion 52 in a planar view.

[0040] In the example shown in Figure 11, both the left and right ends of the partition member 62 are provided with fixing portions 621 with through holes, and the partition member 62 is fixed to the mounting angle 22 using screws passed through the through holes of the fixing portions 621.

[0041] Furthermore, in the embodiment, louvers 63 that cover the exhaust holes of the intake and exhaust panel 61 are fixed to the housing 2. More specifically, the louvers 63 that cover the exhaust holes of the intake and exhaust panel 61 are fixed to the dividing plate portion 21. The flow direction of the air coming out of the exhaust holes of the intake and exhaust panel 61 is adjusted by the louvers 63, which can prevent the air coming out of the cooling device 5 from stagnating. As can be understood from these descriptions, it is preferable to place the louvers 63 above the exhaust panel portion 612 of the intake and exhaust panel 61.

[0042] In this embodiment, the blades of the louver 63 are configured to allow air to flow toward the door 23 (see FIGS. 15 and 16). Therefore, even if the electric / electronic device unit 91 is mounted in a state where it protrudes forward from the front surface of the mounting angle 22, the cool air can easily reach the upper part of the housing 2.

[0043] In addition, in the embodiment, a substantially U-shaped cover 64 that covers the intake panel portion 611 of the intake and exhaust panel 61 is fixed to the dividing plate portion 21. Note that the cover 64 may be fixed to the dividing plate portion 21 before the intake and exhaust panel 61 is placed. Because the cover 64 is substantially U-shaped, the intake and exhaust panel 61 can be moved in the space below the cover 64 even when the cover 64 is fixed.

[0044] Furthermore, by installing the cover 64, air from the rear side of the housing 2 can be more easily taken in by the cooling device 5. This makes it possible to create a large amount of air circulation within the housing 2. Furthermore, if the mounted electric / electronic device unit 91 has a front intake / rear exhaust structure, the air exhausted from the electric / electronic device unit 91 tends to move to the rear side of the housing 2. In such a case, it can be expected that the air exhausted from the electric / electronic device unit 91 will be guided to the cooling device 5 quickly.

[0045] As can be understood from these descriptions, it is preferable to provide a cover 64 above the intake panel portion 611 of the intake and exhaust panel 61 so that an intake passage is formed between the dividing plate portion 21 and the cover 64.

[0046] Note that changing from the state before the intake and exhaust unit is installed to the state after installation results in, for example, the state shown in Fig. 13 changing to the state shown in Fig. 14. The intake and exhaust panel 61 is arranged so as to be in contact with the cooling device 5 from above through the communication space 20c. The intake and exhaust panel 61 of the example shown in Fig. 13 is provided with a packing 613 on the side facing the cooling device 5, which makes it difficult for a gap to form between the intake and exhaust panel 61 and the upper surface of the cooling device 5. Note that it is preferable to arrange the packing 613 provided on the intake and exhaust panel 61 so as to be in contact with the cooling device 5 at a position between the intake hole 51 and the exhaust hole 52 in a plan view.

[0047] Furthermore, when the intake / exhaust panel 61 is in contact with the cooling device 5, the intake panel portion 611, which is the surface of the intake / exhaust panel 61 having intake holes, and the exhaust panel portion 612, which is the surface having exhaust holes, are vertically misaligned in height. To make this possible, a wall portion 614 extending in the vertical direction is provided between the two surfaces. This wall portion 614 may be used to suppress air movement along the underside of the intake / exhaust panel 61. In other words, the wall portion 614 provided on the intake / exhaust panel 61 may be positioned so as to be in contact with the cooling device 5 at a position between the intake holes 51 and the exhaust holes 52 in a plan view.

[0048] 13, intake panel section 611 is configured to be located lower than exhaust panel section 612, but the opposite positional relationship is also possible. Note that by differentiating the thickness of packing 613 provided on intake panel section 611 and the thickness of packing 613 provided on exhaust panel section 612 and adjusting them, it is possible to suppress rattling of intake and exhaust panel 61 when placed on cooling device 5, regardless of the difference in height of each panel section.

[0049] 13, a partition member 62 disposed on an intake / exhaust panel 61 is configured to have a crank shape in a side view. This partition member 62 is configured so that its upper portion is positioned further forward than its lower portion, and can function to release air exhausted from the cooling device 5 at a position away from the intake holes.

[0050] As can be seen from these descriptions, the intake and exhaust panel 61 is preferably formed in a crank shape so that the height of the holes in the intake panel portion 611 and the height of the holes in the exhaust panel portion 612 are different.

[0051] 14, the upper end of the partition member 62 is configured to be higher than the upper end of the louver 63. In this way, the partition member 62 can prevent the air released from the louver 63 from moving backward. In the embodiment, the air release direction determined by the louver 63 is a direction away from the partition member 62, and therefore, in this respect as well, the air released from the louver 63 can be prevented from moving backward.

[0052] Furthermore, by providing the electrical / electronic equipment storage box EB with an intake / exhaust unit, the unit storage space 20a can be cooled efficiently even if the exhaust hole 52 and the intake hole 51 of the cooling device 5 are adjacent to each other. Also, if the intake / exhaust panel 61 can be fixed by fixing the partition member 62, the efficiency of the installation work can be improved.

[0053] Incidentally, the cooling device 5 is preferably a compressor-type cooling device 5 equipped with an evaporator, a compressor 58, a heat exchanger, etc. In the example shown in Fig. 15, the front side of the cooling device 5 is equipped with an intake hole 51 that draws air from the unit storage space 20a, a first heat exchanger 54 that comes into contact with the air taken in through the intake hole 51 and exchanges heat with it, an exhaust hole 52 that returns the air cooled by the first heat exchanger 54 to the unit storage space 20a, and a first ventilation fan 56 that creates an air flow from the intake hole 51 to the exhaust hole 52.

[0054] The cooling device 5 also includes a second heat exchanger 55 that is heated by the first heat exchanger 54. The second heat exchanger 55 can dissipate heat by the flow of air moving around the second heat exchanger 55. In this embodiment, the second ventilation fan 57 is driven so that cool air taken in through the intake holes 241 of the front panel 24 of the housing 2 is directed at the second heat exchanger 55 and then released through the exhaust holes 271 of the rear panel 27. With this configuration, the air that has been warmed by contact with the second heat exchanger 55 can be released through the exhaust holes 271 of the rear panel 27 (see FIG. 16 ).

[0055] As can be understood from these descriptions, the cooling device 5 has separate paths connecting the intake hole portion 51 and the exhaust hole portion 52, and paths through which air passing between the housing panels provided in the electrical and electronic equipment storage box EB passes.

[0056] The cooling device 5 of this embodiment has a display unit 59 on its front side (see FIG. 17). The front side of the cooling device 5 also has an exhaust hole 52 and an intake hole 51 that are used to cool the unit storage space 20a. The cooling device 5 also has a duct 53 that creates an air path extending in the front-to-rear direction inside the cooling device storage space 20b. The duct 53 shown in FIG. 17 is used to send air taken in through an intake port 531 located on the front side of the cooling device 5 to an exhaust port 532 located on the rear side of the cooling device 5. For this reason, the rear end of the duct 53 faces the rear panel 27. The air that moves through the duct 53 is exhausted to the outside of the electrical / electronic device storage box EB through an exhaust hole 271 in the rear panel 27.

[0057] In the embodiment, a wiring space 20ba is provided between the duct portion 53 and the side surface of the housing 2, through which electrical wires, communication lines, and the like can be passed. In the example shown in FIG. 18 , the exhaust port 532 of the duct portion 53 is configured to be positioned off to the right, so that the wiring space 20ba is located to the left of the rear of the duct portion 53. Of course, the exhaust port 532 of the duct portion 53 may be configured to be positioned off to the left, so that the wiring space 20ba is located to the right of the duct portion 53, or the wiring space 20ba may be provided on the right or left side of the front of the duct portion 53. In this case, the intake port 531 may be configured to be off to the left or right. In the embodiment, the exhaust hole 271 of the rear panel 27 and the exhaust port 532 of the duct portion are formed to abut or face each other, but they may also abut against the intake hole 241 of the front panel 24.

[0058] As can be understood from these descriptions, the electrical and electronic equipment storage box EB has, inside the housing 2, a partition plate portion 21, a unit storage space 20a located above the partition plate portion 21, and a cooling device storage space 20b located below the partition plate portion 21, and the cooling device 5 stored in the cooling device storage space 20b has an intake hole portion 51 used to draw in air from the unit storage space 20a that stores the electrical and electronic equipment unit 91, an exhaust hole portion 52 used to exhaust the air drawn in from the intake hole portion 51 to the unit storage space 20a after cooling, a duct portion 53 extending forward and backward in the cooling device storage space 20b, The duct portion 53 preferably has an intake port 531 used to draw air outside the cooling device 5 into the cooling device 5 or an exhaust port 532 used to exhaust air inside the cooling device 5 to the outside of the cooling device 5, a housing panel is provided at at least one of the front and rear ends of the housing 2, and at least one of the exhaust port 532 and the intake port 531 of the duct portion 53 is biased to one of the left and right sides of the duct portion 53 and to one of the left and right sides of the housing 2, and a wiring space 20ba surrounded by the side of the housing 2, the duct portion 53, and the housing panel. In this way, it is possible to place the cooling device 5 at the bottom of the electrical and electronic device storage box EB while making it easy to secure a wiring path at the bottom of the electrical and electronic device storage box EB.

[0059] As long as wiring space 20ba is simply ensured, duct portion 53 may have any shape as long as that requirement is met. However, in order to quickly exhaust heated air, it is preferable to avoid creating any areas within duct portion 53 where air is difficult to flow. For this reason, it is preferable to configure duct portion 53 so that it has gradually narrowing constricted portions 533 at locations where the left-to-right width is narrowed. For example, the left-to-right width within duct portion 53 is gradually narrowed by using inclined surfaces 534 that are inclined obliquely relative to the front-to-rear direction in a plan view.

[0060] 18, wiring space 20ba is surrounded by inclined surface 534, side plates 25 forming the sides of housing 2, and rear panel 27. By configuring inclined surface 534, the side surfaces of housing 2, and rear panel 27 to be positioned around wiring space 20ba in a plan view, it is possible to use the corner at the rear end of housing 2 as wiring space 20ba while ensuring an appropriate air flow in duct portion 53.

[0061] As can be understood from these descriptions, the duct portion 53 has a narrowing portion 533 at least on one of the front end side and the rear end side, in which the width of the inside left and right gradually decreases, and the narrowing portion 533 has an inclined surface 534 that gradually shortens the distance between the right side surface and the left side surface toward the end side of the duct portion 53, and it is preferable that the configuration has a wiring space 20ba surrounded by the side surface of the housing 2, the inclined surface 534 of the duct portion 53, and the housing panel.

[0062] 18 to 20, an input / output wiring section 21a through which electric wires and the like can be passed is provided on the rear side of the dividing plate section 21, making it possible to route electric wires and the like across the unit housing space 20a and the cooling device housing space 20b. This makes it possible to route electric wires and the like introduced into the unit housing space 20a from outside the housing 2, or electric wires of the electric electronic device unit 91 provided in the unit housing space 20a, into the cooling device housing space 20b.

[0063] Furthermore, the electric wires routed in the cooling device storage space 20b can be routed outside the housing 2 from the rear side of the housing 2. In the example shown in FIG. 20, the electric wires can be routed outside through the wiring inlet / outlet portion 11 of the rear wiring panel 28, which is provided separately from the rear panel 27. By configuring the electric wires to be routed through the rear wiring panel 28, which is independent of the rear panel 27, it is possible to prevent the electric wires routed out from the rear of the housing 2 from getting in the way when inspecting the second ventilation fan 57, compressor 58, etc. of the cooling device 5. Conversely, when it is desired to inspect only the wiring, the inspection can be performed by removing only the rear wiring panel 28.

[0064] As can be understood from these descriptions, it is preferable to provide a housing panel having ventilation holes, which are intake holes 241 and exhaust holes 271, on the surface facing intake port 531 or exhaust port 532 of duct section 53, and to provide a wiring panel 28, through which electric wires can be passed, next to the housing panel having the ventilation holes.

[0065] In the embodiment, the wires coming out from the lower rear surface of the housing 2 are limited to the location where the rear wiring panel 28 is located, which makes it easier to avoid electric wires passing through the wiring space 20ba getting tangled in the cooling device 5 when the cooling device 5 is pulled out or stored during inspection or replacement (see Figure 21).

[0066] 19 and 22, the second ventilation fan 57 is disposed so as to be biased toward the side where the exhaust port 532 of the duct portion 53 is biased, and the center of the second ventilation fan 57 faces the exhaust port 532 when viewed from the rear. Meanwhile, the compressor 58 that generates heat within the cooling device 5 is disposed so as to be biased toward the side opposite the side where the exhaust port 532 of the duct portion 53 is biased, and is adjacent to the inclined surface 534. This allows the exhaust air from the second ventilation fan 57 that is directed toward the compressor 58 to flow along the inclined surface 534 to the exhaust port 532. This prevents heat from pooling around the compressor 58, which is a heat-generating element. Note that the heat-generating element does not have to be the compressor. A similar effect can be obtained by disposing the heat-generating element next to the inclined surface 534.

[0067] As can be understood from these descriptions, the cooling device 5 is preferably configured such that the exhaust port 532 of the duct portion 53 is biased to one of the left and right sides of the duct portion 53, a ventilation fan and a heating element are provided inside the duct, the ventilation fan is biased to one of the left and right sides of the duct portion 53 so as to face the exhaust port 532, and at least a portion of the heating element overlaps with the inclined surface 534 when viewed in the front-to-rear direction.

[0068] While the present invention has been described above using exemplary embodiments, the present invention is not limited to the above embodiments and can be embodied in various forms. For example, the wiring space does not need to be located adjacent to the location where the wiring enters and exits the housing. In this case, the wiring space can be used as a wiring space through which electric wires connecting electrical and electronic devices arranged within the housing can be passed.
