[0009] As shown in Figure 1, the electronic device 10 is, for example, a control device for controlling industrial machinery. Industrial machinery is, for example, a robot, but is not limited to this. The electronic device 10 comprises a housing 12, a power supply unit 14 (see Figure 2), an electrical load 16, a connection board (board) 18, a first fan 20, and a second fan 22 (see Figure 3).

[0010] The housing 12 has, for example, a rectangular parallelepiped shape. The housing 12 comprises a bottom plate 24 (see Figure 3), a top plate 26, and four side plates 28, 30, 32, and 34. As shown in Figure 3, the bottom plate 24, the top plate 26, and the four side plates 28, 30, 32, and 34 are each formed in a rectangular shape. The material of the bottom plate 24, the top plate 26, and the four side plates 28, 30, 32, and 34 is, for example, a metal material.

[0011] In the following description, the front-to-back direction (depth direction) of the enclosure 12 will be referred to as the X direction. The X direction is the shorter side direction of the enclosure 12. The bottom plate 24 is aligned with the X direction. The direction from rear to front will be referred to as the X1 direction. The direction from front to rear (opposite direction to the X1 direction) will be referred to as the X2 direction.

[0012] The direction perpendicular to the X direction and along the bottom plate 24 is referred to as the Y direction. The Y direction is the longitudinal direction (width direction) of the housing 12. The direction from side plate 32 toward side plate 30 is referred to as the Y1 direction. The direction from side plate 30 toward side plate 32 (opposite direction to the Y1 direction) is referred to as the Y2 direction.

[0013] The Z direction is perpendicular to the X and Y directions. The Z direction is the height direction of the housing 12. The direction from the top plate 26 toward the bottom plate 24 is called the Z1 direction. The direction from the bottom plate 24 toward the top plate 26 (opposite direction to the Z1 direction) is called the Z2 direction.

[0014] The side panel 28 is the front panel 38 of the housing 12. The side panel 34 is the rear panel 40 of the housing 12. The bottom plate 24, the front panel 38, and the rear panel 40 are integrally formed. Alternatively, the bottom plate 24 and the rear panel 40 may be integrally formed, and the front panel 38 may be detachable from the bottom plate 24.

[0015] The top plate 26, side plate 30, and side plate 32 are integrally formed. The integrally formed top plate 26, side plate 30, and side plate 32 are detachable from the bottom plate 24 in the Z direction.

[0016] An enclosure space 36 is formed inside the enclosure 12. The bottom plate 24, the top plate 26, the two side plates 30 and 32, the front panel 38, and the rear panel 40 define the enclosure space 36.

[0017] As shown in Figure 2, the connecting board 18 is arranged within the housing space 36. Within the housing space 36, the connecting board 18 is positioned between the center in the Y direction and the side plate 30 on the Y1 direction side. Within the housing space 36, the connecting board 18 is positioned along the direction from the front panel 38 toward the rear panel 40. The connecting board 18 is positioned along the direction intersecting the bottom plate 24. More specifically, the connecting board 18 is positioned along the X and Z directions. The connecting board 18 has a first surface 18a, which is the surface on the Y1 direction side, and a second surface 18b, which is the surface on the Y2 direction side.

[0018] Figure 4 is a schematic front view of the electronic device 10. In Figure 4, the outer shape of the housing 12 is shown by a dashed line. The connecting board 18 divides the housing space 36 into a first partial space 36a and a second partial space 36b.

[0019] The first partial space 36a is the internal space of the housing space 36 on the Y1 direction side of the connection board 18. The first partial space 36a is defined by the first surface 18a of the connection board 18, the bottom plate 24 (see Figure 3), the side plate 30 on the Y1 direction side, the top plate 26, the front panel 38, and the rear panel 40. In addition, in the first partial space 36a, the dimensions in the X direction are larger than the dimensions in the Y direction (see Figures 5 and 6). The X direction is the longitudinal direction of the first partial space 36a. The front panel 38 defines one end of the first partial space 36a in the longitudinal direction. The rear panel 40 defines the other end of the first partial space 36a in the longitudinal direction.

[0020] The second partial space 36b is the internal space of the housing space 36 on the Y2 direction side of the connection board 18. The second partial space 36b is adjacent to the first partial space 36a via the connection board 18. The second partial space 36b is defined by the second surface 18b of the connection board 18, the bottom plate 24, the top plate 26, the side plate 32 on the Y2 direction side, the front panel 38, and the rear panel 40. As described above, the connection board 18 is located on the Y1 direction side within the housing space 36. Therefore, the first partial space 36a is narrower than the second partial space 36b.

[0021] The power supply unit 14 is located within the first partial space 36a. The power supply unit 14 comprises a plurality of power circuit boards (boards) 42. In this embodiment, the power supply unit 14 includes two power circuit boards 42. The two power circuit boards 42 are located within the first partial space 36a with a gap between them in the Z direction. As shown in Figure 2, the two power circuit boards 42 are connected via one or more connecting members 44. Each of the two power circuit boards 42 extends along the X and Y directions. The two power circuit boards 42 are electrically connected to each other by connectors (not shown) without the use of cables.

[0022] As shown in Figure 4, the electrical load 16 is arranged in the second partial space 36b. The electrical load 16 includes a control board (board) 46 and a drive board (board) 48. The control board 46 and the drive board 48 are arranged in the second partial space 36b with a gap in the Z direction. The control board 46 is located on the Z2 direction side (top plate 26 side) of the second partial space 36b. The drive board 48 is located on the Z1 direction side (bottom plate 24 side) of the second partial space 36b. As shown in Figure 2, the control board 46 and the drive board 48 are connected via one or more connecting members 50. Each of the control board 46 and the drive board 48 extends along the X direction and the Y direction, respectively. The control board 46 and the drive board 48 are electrically connected to each other by a connector (not shown) without the use of cables.

[0023] Figures 5 and 6 are plan views of an electronic device 10 according to one embodiment. In Figure 5, the top plate 26 and the two side plates 30 and 32 (see Figure 3) are omitted from the illustration. In Figure 6, the top plate 26, the two side plates 30 and 32, the power circuit board 42 on the Z2 direction side (see Figure 4), and the control board 46 are omitted from the illustration.

[0024] As shown in Figures 5 and 6, the connection board 18 electrically connects the power supply unit 14 and the electrical load 16. Specifically, the connection board 18 has a plurality of first connection connectors 52 and a plurality of second connection connectors 54.

[0025] Multiple first connection connectors 52 are provided on the first surface 18a of the connection board 18. The first connection connectors 52 are male connectors. Each of the two power circuit boards 42 of the power supply unit 14 is provided with multiple power supply side connectors 56. The power supply side connectors 56 are female connectors. The first connection connectors 52 are electrically connected to the power supply side connectors 56 by mating with them. Note that the first connection connectors 52 may be female connectors and the power supply side connectors 56 may be male connectors.

[0026] Multiple second connection connectors 54 are provided on the second surface 18b of the connection board 18. The second connection connectors 54 are male connectors. The control board 46 and drive board 48 of the electrical load 16 are each provided with multiple load-side connectors 58. The load-side connectors 58 are female connectors. The second connection connectors 54 are electrically connected to the load-side connectors 58 by mating with them. Note that the second connection connectors 54 may be female connectors and the load-side connectors 58 may be male connectors.

[0027] The housing 12 has a plurality of ventilation openings 60 that communicate with the first partial space 36a. The plurality of ventilation openings 60 include a first ventilation opening 60a and a second ventilation opening 60b.

[0028] The first vent 60a is provided in the front panel 38. More specifically, the first vent 60a is provided in the portion of the front panel 38 that defines the first partial space 36a. The first vent 60a is a first intake port 62 that communicates with the first partial space 36a.

[0029] The second vent 60b is provided in the portion of the rear panel 40 that defines the first partial space 36a. The second vent 60b is the first exhaust port 64 that communicates with the first partial space 36a.

[0030] The first exhaust port 64 is equipped with a first fan 20. Specifically, the first fan 20 is provided in the portion of the rear panel 40 that defines the first exhaust port 64. The first fan 20 is a fan that cools the power supply unit 14 by circulating cooling air into the first partial space 36a.

[0031] The enclosure 12 further includes a second air intake port 66, a second exhaust port 68, and a second fan 22.

[0032] The second air intake port 66 is provided in the portion of the front panel 38 that defines the second partial space 36b. More specifically, the second air intake port 66 is provided in the Y2 direction portion of the front panel 38. The second air intake port 66 communicates with the second partial space 36b.

[0033] The second exhaust port 68 is provided in the portion of the rear panel 40 that defines the second partial space 36b. The second exhaust port 68 communicates with the second partial space 36b. In this embodiment, the rear panel 40 is provided with a plurality of second exhaust ports 68 (two second exhaust ports 68 in Figures 5 and 6). The two second exhaust ports 68 are spaced apart in the Y direction.

[0034] Each of the two second exhaust ports 68 is equipped with a second fan 22. Specifically, the second fan 22 is provided in the portion of the rear panel 40 that defines the second exhaust port 68. The second fan 22 is a fan for cooling the electrical load 16 by circulating cooling air into the second partial space 36b.

[0035] The front panel 38 is provided with a power connector 70. The power connector 70 is electrically connected to a connector (not shown) on the power circuit board 42 of the power supply unit 14. When the power connector 70 is electrically connected to a power cable (not shown) outside the housing 12, AC power can be supplied to the power supply unit 14 from an external power supply (not shown).

[0036] The operation of an electronic device 10 according to one embodiment will be described.

[0037] When AC power is supplied to the power supply unit 14 from an external power source (not shown), the power circuit board 42 of the power supply unit 14 converts the supplied AC power into DC power. The power circuit board 42 supplies this DC power to the electrical load 16 via the connection board 18. At this time, the connection board 18 functions as a relay board that relays the supply of DC power from the power circuit board 42 to the electrical load 16.

[0038] Specifically, the power circuit board 42 outputs DC power to the connection board 18 via the power supply side connector 56 and the first connection connector 52. The connection board 18 outputs the DC power to the control board 46 via the second connection connector 54 and the load side connector 58. The connection board 18 also outputs the DC power to the drive board 48 via the second connection connector 54 and the load side connector 58.

[0039] The control board 46 operates using DC power supplied from the power circuit board 42 to control an industrial machine (not shown) located outside the electronic device 10. The drive board 48 operates using DC power supplied from the power circuit board 42 to drive a motor provided in the industrial machine.

[0040] The power supply unit 14 and the electrical load 16 each generate heat during operation. The control board 46 drives the first fan 20 by supplying DC power to it in order to cool the power supply unit 14. The control board 46 also drives the two second fans 22 by supplying DC power to them in order to cool the electrical load 16.

[0041] When the first fan 20 is driven, air is taken into the first partial space 36a from the outside of the housing 12 through the first air inlet 62. The connection substrate 18 defines the first partial space 36a and extends along the X direction. Therefore, the air taken into the first partial space 36a flows along the first surface 18a of the connection substrate 18 as cooling air for cooling the power supply unit 14, as indicated by the arrows in FIGS. 5 and 6. The connection substrate 18 guides the cooling air in the X2 direction in the first partial space 36a.

[0042] The power supply unit 14 (two power circuit boards 42) is located between the first air inlet 62 and the first air outlet 64 in the first partial space 36a. Also, the two power circuit boards 42 extend along the X direction. By the cooling air guided to the connection substrate 18 flowing along the X2 direction, the two power circuit boards 42 can be efficiently cooled. The cooling air (air) that has passed through the two power circuit boards 42 is exhausted to the outside of the housing 12 through the first air outlet 64.

[0043] Also, when the second fan 22 is driven, air is taken into the second partial space 36b from the outside of the housing 12 through the second air inlet 66. The air taken into the second partial space 36b flows along the X2 direction as cooling air for cooling the electrical load 16, as indicated by the arrows in FIGS. 5 and 6. In the second partial space 36b, the control board 46 and the drive board 48 are located between the second air inlet 66 and the two second air outlets 68. Also, the control board 46 and the drive board 48 extend along the X direction. By the cooling air flowing along the X2 direction, the control board 46 and the drive board 48 can be efficiently cooled. The cooling air (air) that has passed through the control board 46 and the drive board 48 is exhausted to the outside of the housing 12 through the second air outlets 68.

[0044] FIG. 7 is a front view schematically showing an electronic device 80 according to a comparative example. FIG. 8 is a plan view of the electronic device 80 according to the comparative example. For the same components as those of the electronic device 10 (see FIGS. 1 to 6) according to an embodiment in the electronic device 80 according to the comparative example, the same reference numerals will be used for description.

[0045] In the comparative example electronic device 80, the connection board 18 (see Figure 5) is not located within the housing space 36. Therefore, the housing space 36 is not divided into a first partial space 36a and a second partial space 36b, and the power supply unit 14 and the electrical load 16 are located within a single housing space 36. Furthermore, the power supply unit 14 and the electrical load 16 are electrically connected via a plurality of cables 82. In addition, the comparative example electronic device 80 does not have a first air intake port 62 (see Figure 5) on the front panel 38. Figures 7 and 8 schematically illustrate the power supply unit 14.

[0046] As shown in Figure 8, in the comparative electronic device 80, when the first fan 20 and the second fan 22 are driven, air is drawn into the housing space 36 via the second intake port 66. The drawn-in air flows as cooling air through the housing space 36 toward the first exhaust port 64 and the two second exhaust ports 68. In the comparative electronic device 80, as indicated by the arrows in Figure 8, most of the cooling air flows through the housing space 36 toward the second exhaust ports 68. The cooling air flowing from the second intake port 66 toward the first exhaust port 64 passes through the portion of the power supply unit 14 on the X2 direction side. Therefore, the power supply unit 14 cannot be cooled overall in the comparative electronic device 80. Also, as shown in Figure 7, in the comparative electronic device 80, multiple cables 82 are arranged between the power supply unit 14 and the electrical load 16, so the multiple cables 82 may obstruct the flow of cooling air that cools the power supply unit 14. Thus, the power supply unit 14 cannot be cooled efficiently in the comparative electronic device 80. In the comparative example electronic device 80, the cooling efficiency of the power supply unit 14 decreases.

[0047] In contrast, as shown in Figures 5 and 6, respectively, in the electronic device 10 according to one embodiment, a connection board 18 that electrically connects the power supply unit 14 and the electrical load 16 defines a first partial space 36a where the power supply unit 14 is located. This allows air taken in from the first air intake 62 into the first partial space 36a to be efficiently guided to the power supply unit 14. As a result, the cooling of the power supply unit 14 can be promoted, and the cooling efficiency of the power supply unit 14 can be improved.

[0048] Further, the connection board 18 is electrically connected to the power supply unit 14 via the first connection connector 52 and is also electrically connected to the electrical load 16 via the second connection connector 54. That is, in the electronic device 10, since the cable 82 (see FIG. 7) is not used, it is possible to avoid the air flow being obstructed by the cable 82.

[0049] In addition, in the electronic device 10 according to one embodiment, it is not limited to the case where the first fan 20 is provided at the first exhaust port 64. In the electronic device 10, the first fan 20 may be provided at the first intake port 62. Alternatively, in the electronic device 10, the first fan 20 may be provided at each of the first intake port 62 and the first exhaust port 64.

[0050] In the electronic device 10, it is not limited to the case where the first intake port 62 is provided in the front panel 38 and the first exhaust port 64 is provided in the rear panel 40. In the electronic device 10, the first intake port 62 may be provided in the rear panel 40 and the first exhaust port 64 may be provided in the front panel 38. That is, in the electronic device 10, the first intake port 62 and the first exhaust port 64 may be provided in the housing 12 so as to communicate with the first partial space 36a.

[0051] In the electronic device 10, it is not limited to the case where the second fan 22 is provided at the second exhaust port 68. In the electronic device 10, the second fan 22 may be provided at the second intake port 66. Alternatively, in the electronic device 10, the second fan 22 may be provided at each of the second intake port 66 and the second exhaust port 68.

[0052] In the electronic device 10, it is not limited to the case where the second intake port 66 is provided in the front panel 38 and the second exhaust port 68 is provided in the rear panel 40. In the electronic device 10, the second intake port 66 may be provided in the rear panel 40 and the second exhaust port 68 may be provided in the front panel 38. That is, in the electronic device 10, the second intake port 66 and the second exhaust port 68 may be provided in the housing 12 so as to communicate with the second partial space 36b.

[0053] In the electronic device 10, it is not limited to the case where the electrical load 16 includes both the control board 46 and the drive board 48. In the electronic device 10, the electrical load 16 may include at least either the control board 46 or the drive board 48.

[0054] In the electronic device 10, the longitudinal direction of the first partial space 36a is not limited to the X direction. The longitudinal direction of the first partial space 36a may be the Y direction. Also, in the electronic device 10, the power supply unit 14 is not limited to being arranged in the first partial space 36a along the X direction. The power supply unit 14 may be arranged in the first partial space 36a along the Y direction.
