[0011] 1. Electronic equipment (1) Overview of electronic equipment Hereinafter, an overview of an electronic device 100 according to an embodiment of the present invention will be described with reference to the drawings. Figure 1 (a) is a schematic diagram (1) showing the configuration of each device component within the electronic device device involved in the embodiment of the present invention, (b) is a schematic diagram (2) showing the configuration of each device component within the electronic device device involved in the embodiment of the present invention, (c) is a schematic diagram (3) showing the configuration of each device component within the electronic device device involved in the embodiment of the present invention, and (d) is a schematic diagram (4) showing the configuration of each device component within the electronic device device involved in the embodiment of the present invention.

[0012] Electronic device 100 is a device capable of internally accommodating various device components and a cooling device for cooling these components. For example, electronic device 100 is configured to generate various outputs, such as current and voltage, from the various device components disposed therein. For example, electronic device 100 is an evaluation test device for evaluating the output current and output voltage of a developed device. However, electronic device 100 is not limited to an evaluation test device, as long as it is configured to cool the various device components disposed therein.

[0013] Hereinafter, the x direction of the electronic device 100 is referred to as the height direction x, the y direction perpendicular to the height direction x is referred to as the width direction y, and the z direction perpendicular to the height direction x and the width direction y is referred to as the length direction z. In the height direction x, expressions such as upper side, top, upper, lower side, bottom, and lower are used. In the length direction z, the side of the front panel 24e described later is referred to as the front side, front face, and front, and the side of the rear panel 24f is referred to as the rear side, rear face, and rear. In the width direction y, the left and right directions in the front view are referred to as the left side, left, right side, and right.

[0014] The electronic device 100 includes at least one module 10 and an electronic device housing (not shown) for housing the at least one module 10. Figure 1 In the examples (a) to (d) of FIG, a side view of a module 10 taken out from an electronic device housing is shown. The electronic device housing has a frame body (not shown) and an exterior panel (not shown). The frame body is formed by combining a plurality of frame parts, constituting the skeleton of the electronic device housing. The exterior panel is installed in a manner covering the skeleton of the frame body. At least one module 10 is accommodated inside the electronic device housing. The module 10 is formed into a cylindrical shape by combining a plate-like wall body 60, and various device components 30, 40, etc. are accommodated inside it.

[0015] exist Figure 1In the examples (a) to (d), the module 10 has a first equipment component 30, a second equipment component 40, and a fan 50 inside. The fan 50 forms wind inside the module 10. The wind formed by the fan 50 forms a ventilation channel 53 for air flow inside the module 10. The ventilation channel 53 is along the ventilation direction VD of the wind formed by the fan 50. The fan 50 is arranged on the upstream side US (UpStream) of the ventilation channel 53. The first equipment component 30 and the second equipment component 40 are arranged on the downstream side DS (DownStream) of the fan 50. The first equipment component 30 is electrically connected to the second equipment component 40, and the second equipment component 40 is capable of at least either supplying current to the first equipment component 30 or receiving current from the first equipment component 30. Here, the meaning of the second equipment component 40 supplying current to the first equipment component 30 includes at least either the second equipment component 40 itself supplying current to the first equipment component 30, or supplying current to the first equipment component 30 via the second equipment component 40. In addition, the meaning of the second device component 40 receiving current from the first device component 30 includes at least one of the second device component 40 itself receiving current from the first device component 30 and other components receiving current via the second device component 40. Figure 1 In the examples (a) to (d) of FIG. 1 , it is assumed that the second device component 40 transmits current to the first device component 30. Outputs such as voltage and current can be generated by the cooperation of the first device component 30 and the second device component 40. Figure 1 In the examples (a) to (d), the first equipment component 30 and the second equipment component 40 are arranged side by side along the ventilation direction VD. When viewed from the ventilation direction perspective VDview, the first equipment component 30 and the second equipment component 40 are staggered so as to only partially overlap in the height direction x.

[0016] According to the above configuration, when viewed from the ventilation direction perspective VDview, since the first equipment component 30 and the second equipment component 40 only partially overlap in the height direction x and are arranged offset, the wind generated by the fan 50 is supplied to both the first equipment component 30 and the second equipment component 40. Thus, the fan 50 can efficiently cool both the first equipment component 30 and the second equipment component 40. Thus, it is possible to provide an electronic device 100 that can cool the equipment components 30 and 40.

[0017] Furthermore, since the first equipment component 30 and the second equipment component 40 partially overlap in the height direction x, the total height of the first equipment component 30 and the second equipment component 40 can be reduced. This allows the fan 50 for supplying air to both the first equipment component 30 and the second equipment component 40 to be compactly formed. This allows the module 10 integrally including the first equipment component 30, the second equipment component 40, and the fan 50 to be compactly formed.

[0018] The following describes Figure 1 The structures of (a) to (d). Figure 1 In the example of (a), the first equipment component 30 is located closer to the downstream side DS than the second equipment component 40. That is, the fan 50, the second equipment component 40 and the first equipment component 30 are arranged in sequence from the upstream side US to the downstream side DS along the ventilation direction VD. When observed from the ventilation direction perspective VDview, in the width direction y, at least a portion of the fan 50, at least a portion of the second equipment component 40, and at least a portion of the first equipment component 30 overlap. In particular, it is preferred that when observed from the ventilation direction perspective VDview, the center of the width direction y of the fan 50, the center of the width direction y of the second equipment component 40, and the center of the width direction y of the first equipment component 30 are roughly consistent. The second equipment component 40, for example, generates current and transmits the generated current to the first equipment component 30. The first equipment component 30 receives the current transmitted from the second equipment component 40. In addition, the first equipment component 30 is configured to process the current transmitted from the second equipment component 40 and transmit the processed current to the outside of the module 10. Furthermore, when viewed from the ventilation direction perspective VDview, in the height direction x, the first equipment unit 30 is positioned above, and the second equipment unit 40 is positioned below. At this point, when viewed from the ventilation direction perspective VDview, in the height direction x, the lower portion of the first equipment unit 30 overlaps with the upper portion of the second equipment unit 40, and the upper portion of the first equipment unit 30 protrudes upward relative to the second equipment unit 40. That is, when viewed from the ventilation direction perspective VDview, in the height direction x, the first equipment unit 30 has an overlapping portion 30a at its lower portion that partially overlaps with the second equipment unit 40, and a protruding portion 30b above the overlapping portion 30a that protrudes upward relative to the second equipment unit 40.

[0019] According to the above Figure 1In the configuration (a), when viewed from the ventilation direction perspective VDview, the first equipment component 30 overlaps the second equipment component 40 at the overlapping portion 30a, but does not overlap the second equipment component 40 at the protruding portion 30b. Consequently, air from the fan 50 is supplied to substantially the entire second equipment component 40 located on the upstream side US, and at least to the protruding portion 30b of the first equipment component 30. Consequently, the fan 50 can efficiently cool both the first equipment component 30 and the second equipment component 40.

[0020] Furthermore, the second equipment component 40 transmits current to the first equipment component 30, and the first equipment component 30 transmits the processed current to the outside of the module 10. Thus, the current can flow in the order in which the fan 50, the second equipment component 40, and the first equipment component 30 are arranged from the upstream side US to the downstream side DS along the ventilation direction VD. This reduces the need for complex wiring that would otherwise cause the current to detour, allowing the module 10 to be designed simply and compactly as a whole. Specifically, in the above configuration, when current flows in the order of the second equipment component 40 and the first equipment component 30, the second equipment component 40 and the first equipment component 30 are arranged sequentially along the current flow. Consequently, the wiring that transmits current from the second equipment component 40 to the first equipment component 30 simply extends from the second equipment component 40 located upstream to the first equipment component 30 located downstream, eliminating the need for complex, circuitous wiring such as detours. Furthermore, the wiring that transmits current from the first equipment component 30 to the downstream output terminal simply extends from the first equipment component 30 located upstream to the downstream output terminal. In the electronic device 100 according to this embodiment, a relatively large current flows through the first device component 30 and the second device component 40. Therefore, thick wiring, low-flexibility wiring, and the like are used for the wiring between the first device component 30 and the second device component 40, and the wiring between the multiple modules 10. When such relatively rigid and low-flexibility wiring is used, it is difficult to make the wiring circuitous within the module 10 and between the multiple modules 10. From the perspective of simplifying and compacting the structure, it is advantageous to arrange the various device components 30, 40, and the like along the flow of current, as in the electronic device 100 described above.

[0021] In addition, you can also Figure 1 The example of (a) is different, such as Figure 1 The first device component 30 and the second device component 40 are arranged as shown in (b) to (d). Figure 1 (b)~(d), only with Figure 1 The following is a brief description focusing on the different parts of (a).

[0022] exist Figure 1 In the example of (b), Figure 1 Unlike example (a), when observed from the ventilation direction perspective VDview, in the height direction x, the second device component 40 is arranged above and the first device component 30 is arranged below. At this time, when observed from the ventilation direction perspective VDview, in the height direction x, the upper part of the first device component 30 overlaps with the lower part of the second device component 40, and the lower part of the first device component 30 protrudes downward than the second device component 40. That is, when observed from the ventilation direction perspective VDview, in the height direction x, the first device component 30 has an overlapping portion 30a at its upper part that partially overlaps with the second device component 40, and has a protruding portion 30b at the lower part of the overlapping portion 30a that protrudes downward than the second device component 40. In this Figure 1 In the case of (b), Figure 1 Similar to (a), the wind from the fan 50 is also supplied to the substantially entire second equipment component 40 located on the upstream side US, and is supplied to at least the protruding portion 30b of the first equipment component 30. Thus, the fan 50 can be used to efficiently cool both the first equipment component 30 and the second equipment component 40. Figure 1 Similar to (a), the module 10 can be formed simply and compactly along the flow of current.

[0023] exist Figure 1 In the example of (c), Figure 1 Unlike the example (a), the first equipment component 30 is located at the upstream side US relative to the second equipment component 40. That is, the fan 50, the first equipment component 30, and the second equipment component 40 are arranged in sequence from the upstream side US toward the downstream side DS along the ventilation direction VD. Figure 1(a) is the same as that in the case of observing from the ventilation direction perspective VDview, in the height direction x, the first equipment component 30 is arranged above and the second equipment component 40 is arranged below. At this time, when observing from the ventilation direction perspective VDview, in the height direction x, the upper part of the second equipment component 40 overlaps with the lower part of the first equipment component 30, and the lower part of the second equipment component 40 protrudes downward than the first equipment component 30. That is, when observing from the ventilation direction perspective VDview, in the height direction x, the second equipment component 40 has an overlapping portion 40a that overlaps with a part of the first equipment component 30 at its upper part, and a protruding portion 40b that protrudes downward than the first equipment component 30 at the lower part of the overlapping portion 40a. The wind from the fan 50 is supplied to substantially the entire first equipment component 30 located on the upstream side US, and is supplied at least to the protruding portion 40b of the second equipment component 40. As a result, the fan 50 can be used to efficiently cool both the first equipment component 30 and the second equipment component 40. It should be noted that the first device component 30 is configured to process the current transmitted from the second device component 40 and transmit the processed current to the outside of the module 10. Figure 1 In (a), the flow of electric current from the second equipment component 40 toward the first equipment component 30 is from the downstream side DS toward the upstream side US along the ventilation direction VD.

[0024] exist Figure 1 In the example of (d), Figure 1 The same as the example (c) of FIG. 5 , the fan 50, the first equipment component 30 and the second equipment component 40 are arranged in order from the upstream side US to the downstream side DS along the ventilation direction VD. Figure 1 Unlike example (c), when observed from the ventilation direction perspective VDview, in the height direction x, the second device component 40 is arranged above and the first device component 30 is arranged below. At this time, when observed from the ventilation direction perspective VDview, in the height direction x, the lower part of the second device component 40 overlaps with the upper part of the first device component 30, and the upper part of the second device component 40 protrudes upwards than the first device component 30. That is, when observed from the ventilation direction perspective VDview, in the height direction x, the second device component 40 has an overlapping portion 40a at its lower part that partially overlaps with the first device component 30, and has a protruding portion 40b at the upper part of the overlapping portion 40a that protrudes upwards than the first device component 30. In this Figure 1 In case (d), Figure 1Similar to (c), the wind from the fan 50 is also supplied to substantially the entire first equipment component 30 located on the upstream side US, and is also supplied to at least the protruding portion 40b of the second equipment component 40. Thus, the fan 50 can efficiently cool both the first equipment component 30 and the second equipment component 40.

[0025] (2) Specific methods Hereinafter, an example of a specific form of the electronic device 100 according to this embodiment will be described. First, the overall structure of the electronic device 100 will be described.

[0027] The electronic device 100 includes a plurality of modules 10 and an electronic device housing 20. The electronic device 100 is configured such that the plurality of modules 10 are housed within the electronic device housing 20. The electronic device housing 20 includes a frame 21 (described later). Figure 15 ) and an exterior panel 24. In the specific form involved in this embodiment, the electronic device 100, the module 10, and the electronic device housing 20 are in the shape of a cube in which the length direction z is longer than the width direction y, and are square in front and rear views, and are rectangular in side, top, and bottom views.

[0028] The frame body 21 forms the skeleton of the electronic device housing 20 by combining a plurality of frame parts 22, and a plurality of modules 10 are accommodated inside the skeleton. Figures 4 to 7 and the following Figure 15As shown, the frame body 21 has an upper frame portion 22a on the upper side (the first to fourth upper frame portions 22a1 to 22a4), a side frame portion 22b on the side side (the first to fourth side frame portions 22b1 to 22b4), a lower frame portion 22c on the lower side (the first to fourth lower frame portions 22c1 to 22c4), and an auxiliary frame portion 22d (the first to third auxiliary frame portions 22d1 to 22d3).

[0029] The first to fourth lower frame portions 22c1 to 22c4 are sequentially arranged on the left, front, right, and rear sides along the width direction y or the length direction z on the lower side, forming a rectangular frame. The first to fourth upper frame portions 22a1 to 22a4 are sequentially arranged on the left, front, right, and rear sides along the width direction y or the length direction z on the upper side, forming a rectangular frame. The first to fourth lower frame portions 22c1 to 22c4 are each arranged to face each other in the vertical direction with the first to fourth upper frame portions 22a1 to 22a4. The first to fourth side frame portions 22b1 to 22b4 are arranged in sequence along the height direction x on the left front side, right front side, right rear side, and left rear side, between the corners of the first to fourth lower frame portions 22c1 to 22c4 and the corners of the first to fourth upper frame portions 22a1 to 22a4.

[0030] The auxiliary frame portion 22d connects the pair of side frame portions 22b. Specifically, the first auxiliary frame portion 22d1 connects the first and second side frame portions 22b1 and 22b2 at their center in the height direction x along the width direction y. The second auxiliary frame portion 22d2 connects the third and fourth side frame portions 22b3 and 22b4 at their center in the height direction x along the width direction y. The third auxiliary frame portion 22d3 connects the first and third lower frame portions 22c1 and 22c3 at their center in the length direction z along the width direction y.

[0031] like Figure 15 As shown, the plurality of frame portions 22 other than the first upper frame portion 22a1 and the third upper frame portion 22a3 are assembled by welding so that the upper side (the upper panel 24c side) can be opened when viewed from the side of the electronic device housing 20, i.e., in a U-shaped configuration when viewed from the side. The first upper frame portion 22a1 and the third upper frame portion 22a3 are screwed together to the plurality of welded frame portions 22 (the assembly having a U-shaped configuration when viewed from the side) so that the open ends of the openable portions (the U-shaped open portions) of the plurality of welded frame portions 22 are connected to each other. It should be noted that regarding the U-shape in this embodiment, the corners of the U-shape are, for example, approximately right angles.

[0032] The exterior panel 24 covers the space between the frames of the frame body 21 as a skeleton from the outside. The exterior panel 24 has a plate-like shape, and the plate-like surface is supported by the frame body 21. The exterior panel 24 includes a left panel 24a, a right panel 24b, an upper panel 24c, a lower panel 24d, a front panel 24e, and a rear panel 24f. A plurality of slits 54 ( Figures 2 to 5 The plurality of slits 54 are used by the plurality of fans 50 to blow air into the electronic device 100. In addition, the rear panel 24f is provided with a slit 25 ( Figure 3 ), the gap 25 is used to discharge the wind from each of the multiple fans 50 to the outside of the electronic equipment device 100.

[0033] The plurality of modules 10 are each constructed in a state where various equipment components are stored inside, and are in a substantially cubic shape. Figure 2 、 Figures 4 to 7 As shown in the figure, the multiple modules 10 include a first module 10a, a second module 10b, a third module 10c and a fourth module 10d. The above multiple modules 10 are housed inside the electronic device housing 20. Specifically, the first to fourth modules 10a to 10d are arranged in sequence at the upper left, lower left, lower right and upper right of the electronic device housing 20 when viewed from the front. More specifically, the electronic device housing 20 is roughly square in shape when viewed from the front, and the square-shaped partition is roughly divided into four sub-areas, two on the upper and two on the lower. As mentioned above, the first to fourth modules 10a to 10d are respectively housed in the four sub-areas. Here, each module 10a to 10d is arranged in the electronic device housing 20 in such a way that the longitudinal direction of the electronic device housing 20 and the longitudinal direction of the first to fourth modules 10a to 10d are all along the longitudinal direction z.

[0034] At least one module 10 among the plurality of modules 10 includes a fan 50 , a first equipment component 30 , a pair of second equipment components 40 , and a wall 60 .

[0035] The first module 10a is arranged in the upper left of the electronic device 100 in a front view. In the specific method involved in this embodiment, the first module 10a includes a first fan 50a, one or more electrolytic capacitors 35 as a first device component 30, a pair of cooling fins 45 as a pair of second device components 40, and a wall 60. Hereinafter, the case of simply referring to the electrolytic capacitor 35 can be either one electrolytic capacitor 35 or multiple electrolytic capacitors 35. Figures 4 to 7 As shown in FIG. 1 , the wall 60 of the first module 10a is formed into a cubic cylindrical shape by combining a pair of side walls 60a1, an upper wall 60b, and a lower wall 60c1. The interior of the wall 60 of the first module 10a becomes a ventilation passage 53 ( Figure 7 , described later Figure 9 、 Figure 11 The ventilation duct 53 accommodates the first blower 50 a , the electrolytic capacitor 35 , and most or all of the pair of cooling fins 45 .

[0036] The second module 10b is arranged at the lower left of the electronic device 100 when viewed from the front. The second module 10b is formed into a structure substantially the same as that of the first module 10a. In the specific mode involved in this embodiment, the second module 10b includes a second fan 50b, an electrolytic capacitor 35 as a first device component 30, a pair of cooling fins 45 as a pair of second device components 40, and a wall 60. Figures 4 to 7 As shown in FIG. 1 , the wall 60 of the second module 10b is formed by combining a pair of side walls 60a2 and a lower wall 60c2. In the second module 10b, a cubic cylindrical ventilation passage 53 ( Figure 7 The ventilation duct 53 accommodates the second blower 50 b , the electrolytic capacitor 35 , and most or all of the pair of cooling fins 45 .

[0037] The third module 10c is arranged in the lower right corner of the electronic device 100 in a front view. In the specific mode involved in this embodiment, the third module 10c includes a third fan 50c, a transformer 36 as a first device component 30, a pair of reactors 46 as a pair of second device components 40, and a wall 60. Figures 4 to 7 As shown in FIG. 1 , the wall 60 of the third module 10c is formed by combining a pair of side walls 60a3 and a lower wall 60c3. In the third module 10c, the lower wall 60c4 of the fourth module 10d, the pair of side walls 60a3 and the lower wall 60c3 of the third module 10c form a cubic cylindrical ventilation passage 53 ( Figure 7 , described later Figure 12 、 Figure 14 The ventilation duct 53 accommodates the third blower 50 c , the transformer 36 , and most or all of the pair of reactors 46 .

[0038] The fourth module 10d is arranged in the upper right of the electronic device 100 in a front view. In the specific mode involved in this embodiment, the fourth module 10d includes various equipment components and a wall 60 not shown. The various equipment components of the fourth module 10d are relatively difficult to heat. Therefore, no fan is provided in the fourth module 10d. Figures 4 to 7 As shown in FIG. 1 and FIG. 2 , the wall body 60 of the fourth module 10 d is formed by combining a pair of side wall bodies 60 a 4 and a lower wall body 60 c 4 .

[0039] (2-2) Configuration of various equipment components and fans, etc. Next, explain Figures 2 to 8 The specific configuration of the various equipment components 30, 40 and the fan 50 in the electronic device 100 is shown. Hereinafter, the specific configurations 1 and 2 of the various equipment components 30, 40 and the fan 50 in the respective modules 10 will be described, taking the first module 10a and the third module 10c in the electronic device 100 as examples.

[0040] (a) Specific configuration of various equipment components and fans, etc. (a1) Structure of Specific Mode 1 Figure 9 It is a left front upper stereoscopic view of the first module. Figure 10 yes Figure 9 Front view of the first module. Figure 11 It shows Figure 9 A side view showing the positional relationship of multiple equipment components and a fan in the first module.

[0041] The first module 10a includes a first fan 50a, an electrolytic capacitor 35 (an example of the first device component 30), a pair of cooling fins 45 (an example of the second device component 40), and a wall 60. The pair of cooling fins 45 includes an upstream cooling fin 45u and a downstream cooling fin 45d. In addition, the first module 10a includes a pair of electronic components 47 corresponding to the pair of cooling fins 45, namely, an upstream electronic component 47a corresponding to the upstream cooling fin 45u and a downstream electronic component 47b corresponding to the downstream cooling fin 45d. Figures 4 to 7 、 Figure 9 As shown in FIG. 1 , the wall 60 of the first module 10a includes a pair of opposing side walls 60a1, an upper wall 60b, and a lower wall 60c1. In this embodiment, the pair of second equipment components 40 does not include the upstream electronic component 47a and the downstream electronic component 47b, but the pair of second equipment components 40 may also include the upstream electronic component 47a and the downstream electronic component 47b.

[0042] The plate-like surfaces of the pair of side walls 60a1 extend along the xz plane. The plate-like surface of the upper wall 60b extends along the yz plane. The plate-like surface of the lower wall 60c1 extends along the yz plane. Figure 9 As shown, by combining the pair of side walls 60a1, the upper wall 60b and the lower wall 60c1, the wall 60 is formed into a cubic cylindrical shape. Thus, a ventilation channel 53 ( Figure 7 、 Figure 9 、 Figure 11 etc.). Figure 7 、 Figure 9 As shown in FIG. 1 , the lower wall 60c1 of the wall 60 is supported by the first auxiliary frame portion 22d1 and the second auxiliary frame portion 22d2. It should be noted that because the ventilation duct 53 of the first module 10a is separated from the fourth module 10d adjacent in the width direction y, the wind flowing through the ventilation duct 53 of the first module 10a is prevented from flowing out to the fourth module 10d. It should be noted that the fourth module 10d has no or almost no high-heat-generating components, eliminating the need for cooling within the fourth module 10d.

[0043] The ventilation duct 53 of the first module 10a accommodates the first fan 50a, the electrolytic capacitor 35, the pair of cooling fins 45, the upstream electronic components 47a, and the majority of the downstream electronic components 47b. In other words, the ventilation duct 53 is compactly formed to allow the first fan 50a to rotate while accommodating the electrolytic capacitor 35, the pair of cooling fins 45, the upstream electronic components 47a, and the downstream electronic components 47b. A compact ventilation duct 53 is preferred because it allows for a compact design of the first module 10a and the electronic device 100.

[0044] In the ventilation duct 53, the wind generated by the first fan 50a flows along the ventilation direction VD from the upstream side US of the first fan 50a side to the downstream side DS. Along the ventilation direction VD of the ventilation duct 53, the first fan 50a, the upstream cooling fins 45u, the electrolytic capacitor 35, and the downstream cooling fins 45d are arranged in sequence from the upstream side US to the downstream side DS. The upstream cooling fins 45u are one of the pair of cooling fins 45 and are an example of the upstream second device component 41u. The downstream cooling fins 45d are the other of the pair of cooling fins 45 and are an example of the downstream second device component 41d. The upstream electronic components 47a are arranged corresponding to the upstream cooling fins 45u, and the downstream electronic components 47b are arranged corresponding to the downstream cooling fins 45d. In the specific form involved in this embodiment, the upstream electronic components 47a are arranged on the upstream cooling fins 45u, and the downstream electronic components 47b are arranged on the downstream cooling fins 45d. The electrolytic capacitor 35 processes the current transmitted from at least one of the upstream cooling fins 45u and the upstream electronic component 47a, and transmits the processed current to the outside of the first module 10a via at least one of the downstream cooling fins 45d and the downstream electronic component 47b.

[0045] The first fan 50a includes a rotating shaft 51 and a plurality of rotating blades 52. The rotating shaft 51 extends along the ventilation direction VD. The plurality of rotating blades 52 are radially installed with the rotating shaft 51 as the center. Figure 11As shown in FIG. 1 , a plurality of rotating blades 52 are formed with the center 51a ( Figure 10 、 Figure 11 ) is rotated as the center, thereby forming wind flowing from the upstream side US toward the downstream side DS along the ventilation direction VD in the ventilation passage 53.

[0046] The upstream cooling fins 45u mainly cool the upstream electronic components 47a. The upstream electronic components 47a are, for example, various electronic components that generate current to be input to the electrolytic capacitor 35, or units formed by mounting these various electronic components on a substrate. The upstream electronic components 47a receive inputs from, for example, the outside of the electronic device 100 or other modules 10, via or without the upstream cooling fins 45u. Figure 9 、 Figure 10 As shown in FIG. 1 , the upstream cooling fins 45u are formed by arranging a plurality of conductive plate-like components along the XZ plane in the width direction y. The wind from the first blower 50a flows between the plurality of conductive plate-like components along the XZ plane, so that the upstream cooling fins 45u have a heat dissipation effect. By utilizing the upstream cooling fins 45u to cool the upstream electronic components 47a, the heat generation of the upstream electronic components 47a is suppressed, and malfunctions and damages of the upstream electronic components 47a can be suppressed. In addition, malfunctions and damages of the entire electronic device 100 including the upstream electronic components 47a can also be suppressed. The current transmitted from the upstream electronic components 47a is input to the electrolytic capacitor 35 via the upstream cooling fins 45u or without passing through the upstream cooling fins 45u.

[0047] The electrolytic capacitor 35 is a capacitor with a relatively large capacity. Due to its relatively large internal resistance, it is easy to generate heat. The electrolytic capacitor 35 can be used in a power supply circuit, etc., for the electronic device 100 to output various outputs such as current and voltage. In the specific method involved in this embodiment, the electrolytic capacitor 35 receives current from the upstream electronic component 47a, other electronic components, and the outside via the upstream cooling fins 45u or without the upstream cooling fins 45u, and processes the current. In addition, the electrolytic capacitor 35 transmits the processed current to the downstream electronic component 47b and other electronic components via the downstream cooling fins 45d or without the downstream cooling fins 45d, and then transmits it to the outside of the first module 10a.

[0048] The downstream cooling fins 45d primarily cool the downstream electronic components 47b. The downstream electronic components 47b include, for example, various electronic components that process the current supplied from the electrolytic capacitor 35, or units formed by mounting these various electronic components on a substrate. The downstream electronic components 47b receive current from the electrolytic capacitor 35, either through or without the downstream cooling fins 45d. Like the upstream cooling fins 45u, the downstream cooling fins 45d include multiple conductive plate-shaped components extending along the XZ plane. Air that has passed between the multiple conductive plate-shaped components of the upstream cooling fins 45u and air that has passed through the electrolytic capacitor 35 are supplied to the multiple conductive plate-shaped components of the downstream cooling fins 45d. Cooling the downstream electronic components 47b using the downstream cooling fins 45d can suppress heat generation in the downstream electronic components 47b and prevent malfunctions or damage to the downstream electronic components 47b. Furthermore, malfunction or damage of the entire electronic device 100 including the downstream electronic component 47b can be suppressed. The current supplied from the downstream electronic component 47b is supplied to the outside of the electronic device 100 via the downstream cooling fin 45d or without passing through the downstream cooling fin 45d.

[0049] Next, the arrangement of the first fan 50a, the electrolytic capacitor 35, the upstream cooling fins 45u, and the downstream cooling fins 45d will be described. Figure 11 As shown, the first fan 50a, the upstream cooling fins 45u, the electrolytic capacitor 35, and the downstream cooling fins 45d are arranged in this order from the upstream side US toward the downstream side DS along the ventilation direction VD.

[0050] In addition, if Figure 10 、 Figure 11 As shown, when viewed from the ventilation direction perspective VDview, in the height direction x, the electrolytic capacitor 35 is positioned above, and the upstream cooling fin 45u is positioned below. In this case, when viewed from the ventilation direction perspective VDview, in the height direction x, the lower portion of the electrolytic capacitor 35 overlaps with the upper portion of the upstream cooling fin 45u, and the upper portion of the electrolytic capacitor 35 protrudes upward from the upstream cooling fin 45u. That is, when viewed from the ventilation direction perspective VDview, in the height direction x, the electrolytic capacitor 35 has an overlapping portion 30a at its lower portion that partially overlaps with the upstream cooling fin 45u, and a protruding portion 30b above the overlapping portion 30a that protrudes upward from the upstream cooling fin 45u.

[0051] The downstream cooling fins 45d can have a substantially identical structure to the upstream cooling fins 45u and can also be positioned at substantially the same position in the height direction x. In the specific embodiment of this embodiment, the upstream cooling fins 45u and the downstream cooling fins 45d have the same structure and are positioned substantially symmetrically in the length direction z relative to the xy plane located at the center of the electrolytic capacitor 35 in the length direction z. Furthermore, when viewed from the ventilation direction perspective VDview, the upstream cooling fins 45u and the downstream cooling fins 45d are positioned at the same position in the height direction x and the width direction y. Thus, when viewed from the ventilation direction perspective VDview, the electrolytic capacitor 35 is positioned above, and the downstream cooling fins 45d are positioned below. In this case, when viewed from the ventilation direction perspective VDview, the lower portion of the electrolytic capacitor 35 overlaps with the upper portion of the downstream cooling fins 45d in the height direction x, with the upper portion of the electrolytic capacitor 35 protruding upward relative to the downstream cooling fins 45d. That is, when viewed from the ventilation direction perspective VDview, in the height direction x, the electrolytic capacitor 35 has an overlapping portion at its lower portion that partially overlaps with the downstream cooling fin 45d, and has a protruding portion above the overlapping portion that protrudes upward from the downstream cooling fin 45d.

[0052] With the above configuration, air from the first fan 50a is supplied to substantially the entirety of the upstream cooling fins 45u and at least to the protruding portion 30b of the electrolytic capacitor 35. Furthermore, air supplied to the upstream cooling fins 45u and the electrolytic capacitor 35, then passing through the ventilation duct 53, is supplied to the downstream cooling fins 45d. Thus, the first fan 50a can efficiently cool the electrolytic capacitor 35 and the pair of cooling fins 45.

[0053] Furthermore, with the above-described configuration, current flows sequentially from at least one of the upstream cooling fins 45u and the upstream electronic component 47a through the electrolytic capacitor 35 to at least one of the downstream cooling fins 45d and the downstream electronic component 47b, and is then transported to the exterior of the first module 10a. This allows current to flow in the order in which the first fan 50a, upstream cooling fins 45u, electrolytic capacitor 35, and downstream cooling fins 45d are arranged along the ventilation direction VD, from the upstream side US to the downstream side DS. This reduces the need for complex wiring, such as circuitous current routing, and allows for a simple and compact overall design of the first module 10a.

[0054] That is, in the above-described configuration, when current flows sequentially from at least one of the upstream cooling fins 45u and the upstream electronic component 47a to at least one of the downstream cooling fins 45d and the downstream electronic component 47b via the electrolytic capacitor 35, the upstream cooling fins 45u and the upstream electronic component 47a, the electrolytic capacitor 35, and the downstream cooling fins 45d and the downstream electronic component 47b are arranged sequentially from the upstream side US to the downstream side DS along the flow of current. The wiring that transmits current from at least one of the upstream cooling fins 45u and the upstream electronic component 47a to the electrolytic capacitor 35 only needs to extend from the upstream cooling fins 45u and the upstream electronic component 47a arranged on the upstream side toward the electrolytic capacitor 35 arranged on the downstream side, eliminating the need for complicated routing such as detours. Similarly, the wiring that conducts current from the electrolytic capacitor 35 to at least one of the downstream cooling fins 45d and the downstream electronic component 47b can simply extend from the electrolytic capacitor 35 located upstream toward at least one of the downstream cooling fins 45d and the downstream electronic component 47b located downstream, eliminating the need for complex routing such as detours. Furthermore, the wiring that conducts current from at least one of the downstream cooling fins 45d and the downstream electronic component 47b to the downstream output terminal can also simply extend from at least one of the downstream cooling fins 45d and the downstream electronic component 47b located upstream toward the downstream output terminal. In the electronic device 100 according to this embodiment, relatively large current flows through the upstream cooling fins 45u, the upstream electronic component 47a, the electrolytic capacitor 35, the downstream cooling fins 45d, and the downstream electronic component 47b. Consequently, thick wiring or wiring with low flexibility can be used for wiring between components and between multiple modules 10. When using such relatively rigid and inflexible wiring, it is difficult to route the wiring around within the module 10 or between multiple modules 10. From the perspective of simplifying and compacting the structure, it is advantageous to arrange the various device components 30 and 40 along the flow of current, as in the electronic device 100 described above.

[0055] On the other hand, suppose that, unlike the present embodiment, the upstream cooling fins 45u and the upstream electronic component 47a, the downstream cooling fins 45d and the downstream electronic component 47b, and the electrolytic capacitor 35 are arranged in sequence from the upstream side US to the downstream side DS along the ventilation direction VD, and current flows sequentially from at least one of the upstream cooling fins 45u and the upstream electronic component 47a to at least one of the downstream cooling fins 45d and the downstream electronic component 47b via the electrolytic capacitor 35. In this case, the wiring that transmits current from at least one of the upstream cooling fins 45u and the upstream electronic component 47a to the electrolytic capacitor 35 needs to extend from at least one of the upstream cooling fins 45u and the upstream electronic component 47a arranged on the upstream side, bypass the downstream cooling fins 45d and the downstream electronic component 47b, and extend toward the electrolytic capacitor 35 arranged on the downstream side. Furthermore, the wiring that transmits current from the electrolytic capacitor 35 to at least one of the downstream cooling fins 45d and the downstream electronic component 47b must extend from the downstream electrolytic capacitor 35 toward at least one of the upstream downstream cooling fins 45d and the downstream electronic component 47b. Furthermore, the wiring that transmits current from at least one of the downstream cooling fins 45d and the downstream electronic component 47b to the downstream output terminal must bypass the electrolytic capacitor 35 and extend toward the downstream output terminal. This complicates the wiring path. Furthermore, if the wiring is not flexible, it is difficult to reroute the wiring. Furthermore, the increased wiring length can increase resistance.

[0056] Here, when observing from the ventilation direction perspective VDview, as shown in FIG. Figure 10 As shown in FIG. 1 , the rotation range of the first fan 50a, at least a portion of the upstream cooling fin 45u, at least a portion of the electrolytic capacitor 35, and at least a portion of the downstream cooling fin 45d overlap. Here, the rotation range of the first fan 50a is the rotation range of the rotating blades 52 centered about the rotation axis 51. When viewed from the ventilation direction perspective VDview, it is the range of a circle with a rotation diameter 50r centered about the center 51a of the rotation axis. Furthermore, when viewed from the ventilation direction perspective VDview, it is preferable that the center 51a of the rotation axis 51, the center of the upstream cooling fin 45u in the height direction x and the width direction y, the center of the electrolytic capacitor 35 in the height direction x and the width direction y, and the center of the downstream cooling fin 45d in the height direction x and the width direction y are substantially aligned.

[0057] In addition, Figure 10In the example, the distance 35W in the width direction y of the electrolytic capacitor 35 can be designed based on the relationship with the rotation diameter 50r of the rotating blade 52. For example, it can be 0.8≤distance 35W / rotation diameter 50r≤1.7. Figure 10 In the example, the distance in the width direction y of the plurality of electrolytic capacitors 35 is set to a distance 35W. Furthermore, the distance 45W in the width direction y of the cooling fins 45 (upstream cooling fins 45u and downstream cooling fins 45d) can be designed based on the relationship with the rotation diameter 50r of the rotating blades 52. For example, 0.8 ≤ distance 45W / rotation diameter 50r ≤ 1.7 can be achieved. This relationship allows the electrolytic capacitors 35 and the pair of cooling fins 45 to be positioned in a manner corresponding to the rotation range of the first fan 50a. Therefore, the first fan 50a can be compactly formed while efficiently cooling the electrolytic capacitors 35 and the pair of cooling fins 45.

[0058] In the specific mode involved in this embodiment, when viewed from the ventilation direction perspective VDview, the rotation axis 51 (or the center 51a of the rotation axis 51) is located near the upper end 40u of the upstream cooling fin 45u in the height direction x. Figure 10 、 Figure 11 In the example, the rotation shaft 51 is located near and above the upper end 40u of the upstream cooling fin 45u in the height direction x. Alternatively, the rotation shaft 51 may be located near and below the upper end 40u of the upstream cooling fin 45u in the height direction x. Similarly, as shown in the specific mode involved in this embodiment, when viewed from the ventilation direction perspective VDview, the rotation shaft 51 may be located near the upper end of the downstream cooling fin 45d in the height direction x (at Figure 10 、 Figure 11 In the example, it is near and above the upper end).

[0059] In the specific form involved in this embodiment, when viewed from the ventilation direction perspective VDview, the lowest ends 52d of the plurality of rotary blades 52 in the height direction x are located near the lower end 40d of the upstream cooling fin 45u in the height direction x. Figure 10 、 Figure 11In the example of FIG, the lowest end 52d of the plurality of rotating blades 52 in the height direction x is located near and above the lower end 40d of the upstream cooling fin 45u in the height direction x. Alternatively, the lowest end 52d of the plurality of rotating blades 52 in the height direction x may be located near and below the lower end 40d of the upstream cooling fin 45u in the height direction x. Similarly, as shown in the specific method involved in this embodiment, when observed from the ventilation direction perspective VDview, the lowest end 52d of the plurality of rotating blades 52 in the height direction x may be located near the lower end of the downstream cooling fin 45d in the height direction x (at Figure 10 、 Figure 11 In the example, it is near and above the lower end).

[0060] According to the above configuration, when viewed from the ventilation direction perspective VDview, the rotation axis 51 is located near the upper end 40u of the upstream cooling fin 45u in the height direction x, and the lowest end 52d of the plurality of rotating blades 52 in the height direction x is located near the lower end 40d of the upstream cooling fin 45u. In other words, when viewed from the ventilation direction perspective VDview, the rotation ranges of the upstream cooling fin 45u and the plurality of rotating blades 52 substantially overlap. This allows air from the first fan 50a to be supplied to substantially the entirety of the upstream cooling fin 45u located upstream US of the electrolytic capacitor 35, efficiently cooling the upstream cooling fin 45u. Furthermore, since air from the first fan 50a can also be supplied to at least the protruding portion 30b of the electrolytic capacitor 35 that protrudes beyond the upstream cooling fin 45u, the electrolytic capacitor 35 can also be cooled. Furthermore, since the air supplied to the upstream cooling fins 45u and the electrolytic capacitors 35 and then passing through the ventilation duct 53 is supplied to the downstream cooling fins 45d, the downstream cooling fins 45d can also be cooled.

[0061] exist Figure 10 、 Figure 11In the example shown in FIG. 1 , when viewed from the ventilation direction perspective VDview, in the height direction x, in descending order from the highest position, there are the upper end 30u of the electrolytic capacitor 35 (an example of the first equipment component 30 ) in the height direction x, the uppermost end 52u of the rotary blade 52 in the height direction x, the uppermost end 40u of the upstream cooling fin 45u (an example of the second equipment component 40 ) in the height direction x, the lower end 30d of the electrolytic capacitor 35 in the height direction x, the lowermost end 52d of the rotary blade 52 in the height direction x, and the lowermost end 40d of the upstream cooling fin 45u in the height direction x. Here, the distance in the height direction x of the portion of the electrolytic capacitor 35 above the uppermost end 52u of the plurality of rotary blades 52 in the height direction x is referred to as the first distance A1. That is, the first distance A1 is the distance in the height direction x between the upper end 30u and the uppermost end 52u. In addition, the distance in the height direction x of the portion of the upstream cooling fin 45u below the lowest end 52d of the plurality of rotating blades 52 in the height direction x is referred to as the second distance A2. That is, the second distance A2 is the distance in the height direction x between the lowest end 52d and the lower end portion 40d. Figure 10 、 Figure 11 In the example of , the second distance A2 is smaller than the first distance A1. The aforementioned positional relationship and distance relationship can also be applied to the electrolytic capacitor 35, the rotary blade 52, and the downstream cooling fin 45d (an example of the second equipment component 40).

[0062] With this configuration, when viewed from the ventilation direction perspective VDview, the second distance A2 in the height direction x of the upstream cooling fins 45u located outside the rotation range of the plurality of rotating blades 52 is smaller than the first distance A1 in the height direction x of the electrolytic capacitors 35 located outside the rotation range of the plurality of rotating blades 52. This allows air from the first fan 50a to be supplied further to the upstream cooling fins 45u located upstream of the electrolytic capacitors 35, effectively cooling the upstream cooling fins 45u. Furthermore, since the air supplied to the upstream cooling fins 45u and the electrolytic capacitors 35 and then passing through the ventilation duct 53 is supplied to the downstream cooling fins 45d, the downstream cooling fins 45d can also be cooled.

[0063] In addition, if Figure 11 As shown, when viewed from the ventilation direction perspective VDview, the center portion 30m of the electrolytic capacitor 35 in the height direction x may be located above the center 51a of the rotation shaft and the upper end portion 40u of the upstream cooling fin 45u in the height direction x in the height direction x. Similarly, when viewed from the ventilation direction perspective VDview, the center portion 30m may be located above the upper end portion of the downstream cooling fin 45d in the height direction x.

[0064] In addition, if Figure 11 As shown in the figures, the electrolytic capacitor 35 is arranged in the central part of the ventilation direction VD, that is, the longitudinal direction z, in the ventilation duct 53. As a result, it is easy to achieve weight balance of the electrolytic capacitor 35 in the first module 10a, and the electrolytic capacitor 35 can be stably arranged in the first module 10a. In addition, the first module 10a as a whole can achieve stable weight balance. In addition, as mentioned above, the upstream cooling fins 45u and the downstream cooling fins 45d are roughly symmetrical with respect to the xy plane located at the center of the longitudinal direction z of the electrolytic capacitor 35, and are arranged in roughly symmetrical positions. In addition, if the weight of the upstream cooling fins 45u and the downstream cooling fins 45d are roughly the same, the weight balance of the first module 10a as a whole can be achieved by using the electrolytic capacitor 35 arranged in the central part and the upstream cooling fins 45u and the downstream cooling fins 45d that are symmetrically arranged with respect to the electrolytic capacitor 35.

[0065] It should be noted that, in the second module 10b, except for the different structure of the ventilation duct 53 from the first module 10a, the specific configuration of the various equipment components 30, 40, and the fan 50 is substantially the same as that of the first module 10a. For example, in the second module 10b, the second fan 50b, upstream cooling fins 45u (one of the pair of cooling fins 45), electrolytic capacitors 35, and downstream cooling fins 45d (the other of the pair of cooling fins 45) are arranged in sequence along the ventilation direction VD of the ventilation duct 53 from the upstream side US to the downstream side DS. Furthermore, the ventilation duct 53 of the second module 10b can be defined by the lower wall 60c1 of the first module 10a, the pair of side walls 60a2 of the second module 10b, and the lower wall 60c2. Furthermore, the left panel 24a can also contribute to the definition of the ventilation duct 53 of the second module 10b. The side wall 60a2 of the second module 10b may not be used to completely separate the ventilation duct 53 of the second module 10b from the ventilation duct 53 of the third module 10c adjacent in the width direction y. In other words, the air flowing through the ventilation duct 53 of the second module 10b and the air flowing through the ventilation duct 53 of the third module 10c may be mixed before flowing through the ventilation duct 53 of the second module 10b and the ventilation duct 53 of the third module 10c.

[0066] (a2) Structure of a Modification of Specific Mode 1 (i) exist Figure 11In the example shown in FIG. 2 , when viewed from the ventilation direction perspective VDview, the center portion 30m of the electrolytic capacitor 35 in the height direction x is located above the center 51a of the rotation axis and the upper end portion 40u of the upstream cooling fin 45u in the height direction x. Alternatively, the electrolytic capacitor 35 may simply protrude beyond the upstream cooling fin 45u, and the center portion 30m may be located below the center 51a of the rotation axis and the upper end portion 40u in the height direction x. Similarly, the electrolytic capacitor 35 may simply protrude beyond the downstream cooling fin 45d, and the center portion of the downstream cooling fin 45d in the height direction x may be located below the center 51a of the rotation axis and the upper end portion 40u in the height direction x.

[0067] (ii) exist Figures 9 to 11 In the example shown in FIG. 1 , when viewed from the ventilation direction perspective VDview, the rotation axis 51 is located near the upper end 40u of the upstream cooling fin 45u in the height direction x. Alternatively, when viewed from the ventilation direction perspective VDview, the rotation axis 51 (the center 51a of the rotation axis) may be located between the center 40m and the upper end 40u of the upstream cooling fin 45u in the height direction x. That is, when viewed from the ventilation direction perspective VDview, the rotation axis 51 of the first fan 50a can be confined to the range of the upstream cooling fin 45u in the height direction x. Thus, when viewed from the ventilation direction perspective VDview, the upstream cooling fin 45u can be positioned approximately within the rotation range of the plurality of rotating blades 52. Therefore, by supplying air from the first fan 50a to substantially the entire upstream cooling fin 45u, the upstream cooling fin 45u can be efficiently cooled. Similarly, when viewed from the ventilation direction perspective VDview, the rotation shaft 51 may be located between the center portion and the upper end portion of the downstream cooling fin 45d in the height direction x.

[0068] (b) Specific configuration of various equipment components and fans, etc. (b1) Structure of Specific Method 2 Figure 12 It is a right front perspective view of the third module. Figure 13 yes Figure 12 Front view of the third module. Figure 14 It shows Figure 12 A side view showing the positional relationship of multiple equipment components and the fan in the third module.

[0069] The main difference between the third module 10c and the first module 10a is that a transformer 36 is used as an example of the first device component 30, and a pair of reactors 46 is used as an example of a pair of second device components 40. The transformer 36 can be used as a power conversion device. The reactor 46 can be used to generate reactance. The configuration of the various device components 30, 40 and the third fan 50c in the third module 10c is roughly the same as the configuration of the various device components 30, 40 and the first fan 50a in the first module 10a. It should be noted that the structure of the third fan 50c is the same as that of the first fan 50a. The following is a brief description of the structure of the third module 10c.

[0070] The third module 10c includes a third fan 50c, a transformer 36 (an example of the first equipment component 30), a pair of reactors 46 (an example of the second equipment component 40), and a wall 60. Figures 6 and 7 、 Figure 12 As shown in FIG. 1 , the wall 60 of the third module 10c includes a pair of side walls 60a3 extending along the xz plane and facing each other, and a lower wall 60c3 extending along the yz plane. The ventilation passage 53 ( 51.5 mm) of the third module 10c can be formed by the lower wall 60c4 of the fourth module 10d, the pair of side walls 60a3 of the third module 10c, and the lower wall 60c3. Figure 7 、 Figure 12 、 Figure 14 In addition, the right panel 24b can also participate in dividing the ventilation channel 53 of the third module 10c. Figure 7 、 Figure 12 As shown in FIG. 1 , the lower wall 60c3 is supported by the second lower frame portion 22c2 and the fourth lower frame portion 22c4. Figure 6 、 Figure 12 In the example shown in FIG, the upper portion and side portions of one of the pair of reactors 46 (the downstream reactor 46d) are covered by the partition wall 61. It should be noted that the second module 10b and the third module 10c, which are adjacent in the width direction y, do not need to be completely separated, and the side walls 60a3 and 60a2 located between the second module 10b and the third module 10c are relatively low in the height direction x.

[0071] In the ventilation duct 53, air generated by the third fan 50c flows along the ventilation direction VD from the upstream side US of the third fan 50c to the downstream side DS. The third fan 50c, the upstream reactor 46u, the transformer 36, and the downstream reactor 46d are arranged in this order along the ventilation direction VD of the ventilation duct 53, from the upstream side US to the downstream side DS. The transformer 36 receives and processes the current transmitted from the upstream reactor 46u. Furthermore, the transformer 36 is configured to transmit the processed current to the exterior of the third module 10c via the downstream reactor 46d.

[0072] In addition, if Figure 13 、 Figure 14 As shown, when viewed from the ventilation direction perspective VDview, in the height direction x, transformer 36 has an overlapping portion 30a at its lower portion that partially overlaps with upstream reactor 46u, and a protruding portion 30b above the overlapping portion 30a that protrudes upward from upstream reactor 46u. It should be noted that downstream reactor 46d can also have a substantially similar structure to upstream reactor 46u and be positioned at substantially the same position in the height direction x. That is, when viewed from the ventilation direction perspective VDview, in the height direction x, transformer 36 has an overlapping portion at its lower portion that partially overlaps with downstream reactor 46d, and a protruding portion above this overlapping portion that protrudes upward from downstream reactor 46d.

[0073] Here, when observing from the ventilation direction perspective VDview, as shown in FIG. Figure 13 As shown in FIG. 5 , the rotation range of the third fan 50c, that is, the rotation range of the rotor blades 52 about the rotation axis 51, at least a portion of the upstream reactor 46u, at least a portion of the transformer 36, and at least a portion of the downstream reactor 46d overlap. Furthermore, when viewed from the ventilation direction perspective VDview, it is preferable that the center 51a of the rotation axis 51, the centers of the upstream reactor 46u and the downstream reactor 46d in the height direction x and the width direction y, and the centers of the transformer 36 in the height direction x and the width direction y are substantially aligned.

[0074] In addition, Figure 13 In the example, the distance 36W in the width direction y of the transformer 36 is greater than the rotation diameter 50r of the rotor blade 52. For example, the relationship 1.3 ≤ distance 36W / rotation diameter 50r ≤ 1.9 can be satisfied. Furthermore, the distance 46W in the width direction y of the reactor 46 (upstream reactor 46u and downstream reactor 46d) is greater than the rotation diameter 50r of the rotor blade 52. For example, the relationship 1.5 ≤ distance 46W / rotation diameter 50r ≤ 2.1 can be satisfied.

[0075] In addition, Figure 13 In the example shown in FIG. 4 , when viewed from the ventilation direction perspective VDview, the rotary shaft 51 is located near the upper end 40u of the upstream reactor 46u in the height direction x, and the lowest ends 52d of the plurality of rotary blades 52 in the height direction x are located near the lower end 40d of the upstream reactor 46u. The same arrangement as described above can also be applied to the positional relationship of the downstream reactor 46d.

[0076] In addition, Figure 13 、 Figure 14In the example, the distance in the height direction x of the portion of the transformer 36 above the uppermost end 52u of the plurality of rotating blades 52 in the height direction x is defined as a first distance A1. Furthermore, the distance in the height direction x of the portion of the upstream reactor 46u below the lowermost end 52d of the plurality of rotating blades 52 in the height direction x is defined as a second distance A2. The second distance A2 is smaller than the first distance A1. The same arrangement as described above can also be applied to the downstream reactor 46d.

[0077] In addition, if Figure 14 As shown, when viewed from the ventilation direction perspective VDview, the center portion 30m of the transformer 36 in the height direction x may be located above the center 51a of the rotation axis and the upper end portion 40u of the upstream reactor 46u in the height direction x. The same arrangement as described above can also be applied to the downstream reactor 46d.

[0078] In addition, if Figure 14 As shown in FIG. 1 , the transformer 36 is arranged in the central portion of the ventilation duct 53 in the ventilation direction VD, i.e., the longitudinal direction z. As a result, the transformer 36 can be arranged at a position away from the third fan 50c, thereby suppressing adverse effects such as the third fan 50c stopping due to electromagnetic noise from the transformer 36. In addition, it is easy to achieve weight balance of the transformer 36 in the third module 10c, and the transformer 36 can be stably arranged in the third module 10c. In addition, the third module 10c as a whole can achieve stable weight balance. In addition, as Figure 8 as well as Figure 15 As shown, a third auxiliary frame portion 22d3 is disposed in the center portion of the longitudinal direction z where the transformer 36 is disposed. Thus, the transformer 36 is stably supported by the third auxiliary frame portion 22d3 via the lower wall 60c3. Furthermore, the upstream inductor 46u and the downstream inductor 46d are symmetrically shaped with respect to the xy plane located at the center of the longitudinal direction z of the transformer 36 and are disposed in symmetrical positions. Furthermore, if the upstream inductor 46u and the downstream inductor 46d have approximately the same weight, the overall weight of the third module 10c can be balanced by the transformer 36 disposed in the center and the upstream inductor 46u and the downstream inductor 46d disposed symmetrically with respect to the transformer 36.

[0079] (b2) Structure of a modified example of specific embodiment 2 exist Figure 14In the examples shown in FIG. 1 , the transformer 36 is positioned in the center of the ventilation duct 53 in the ventilation direction VD, i.e., in the longitudinal direction z. However, as long as the transformer 36 is positioned to suppress the electromagnetic noise from the transformer 36 on the third fan 50c, its location need not be in the center in the longitudinal direction z. For example, the transformer 36 may be positioned anywhere between the third fan 50c and the downstream end DS of the third module 10c in the longitudinal direction z.

[0080] 2. Assembly method of electronic equipment Figure 15 : is a left upper rear perspective view showing the assembly process of the frame body. Figure 15 As shown, the side frame portion 22b (first to fourth side frame portions 22b1 to 22b4), the lower frame portion 22c (first to fourth lower frame portions 22c1 to 22c4), the second upper frame portion 22a2, the fourth upper frame portion 22a4, and the auxiliary frame portion 22d (first to third auxiliary frame portions 22d1 to 22d3) are assembled by welding their ends. Figure 15 As shown, part of the frame body 21 excluding the first upper frame portion 22a1 and the third upper frame portion 22a3 is formed.

[0081] The part of the frame body 21 assembled in this manner includes a left-side U-shaped portion (an example of a U-shaped portion) 21a when viewed from the left, and a right-side U-shaped portion (an example of a U-shaped portion) 21b when viewed from the right. The left-side U-shaped portion 21a is assembled by welding the first side frame portion 22b1, the fourth side frame portion 22b4, and the first lower frame portion 22c1. The right-side U-shaped portion 21b is assembled by welding the second side frame portion 22b2, the third side frame portion 22b3, and the third lower frame portion 22c3. Thus, the left-side U-shaped portion 21a and the right-side U-shaped portion 21b are formed into a U-shape with the upper side (upper panel 24c side) open. It should be noted that, with respect to the U-shape in this embodiment, the corners of the U-shape are, for example, approximately right angles.

[0082] The aforementioned portion of the frame body 21 includes a front lattice portion 21c when viewed from the front, a rear lattice portion 21d when viewed from the rear, and a lower lattice portion 21e when viewed from above. The front lattice portion 21c is assembled by welding the second upper frame portion 22a2, the first side frame portion 22b1, the second side frame portion 22b2, the second lower frame portion 22c2, and the first auxiliary frame portion 22d1. The first auxiliary frame portion 22d1 connects the middle portion of the first side frame portion 22b1 in the height direction x with the middle portion of the second side frame portion 22b2 in the height direction x. This creates a B-shaped front lattice portion 21c.

[0083] Furthermore, the rear lattice-like portion 21d is assembled by welding the fourth upper frame portion 22a4, the third side frame portion 22b3, the fourth side frame portion 22b4, the fourth lower frame portion 22c4, and the second auxiliary frame portion 22d2. The second auxiliary frame portion 22d2 connects the middle portion of the third side frame portion 22b3 in the height direction x with the middle portion of the fourth side frame portion 22b4 in the height direction x. This forms the rear lattice-like portion 21d into a B-shape.

[0084] The lower lattice section 21e is assembled by welding the first to fourth lower frame sections 22c1 to 22c4 and the third auxiliary frame section 22d3. The third auxiliary frame section 22d3 connects the middle portion of the first lower frame section 22c1 in the longitudinal direction z with the middle portion of the third lower frame section 22c3 in the longitudinal direction z. This forms the lower lattice section 21e in a B-shape.

[0085] Next, a plurality of modules 10 (specifically, first to fourth modules 10a to 10d in this embodiment) are arranged and installed at predetermined positions on a portion of the frame body 21 where the first upper frame portion 22a1 and the third upper frame portion 22a3 have not yet been installed.

[0086] Next, wiring connections etc. are performed between the modules 10. After the wiring connections etc. are completed, Figure 15 As shown, the first upper frame portion 22a1 and the third upper frame portion 22a3 are screwed to a portion of the aforementioned frame body 21. The first upper frame portion 22a1 is screwed to the left side ends of the second upper frame portion 22a2 and the fourth upper frame portion 22a4, as well as the upper ends of the first side frame portion 22b1 and the fourth side frame portion 22b4, by inserting screws (not shown) through screw holes 26. Thus, the first upper frame portion 22a1 is connected to the open end of the left U-shaped portion 21a (the portion where the upper ends of the first side frame portion 22b1 and the fourth side frame portion 22b4 are separated from each other), thereby forming the frame body on the left side. Furthermore, the third upper frame portion 22a3 is screwed to the right side ends of the second upper frame portion 22a2 and the fourth upper frame portion 22a4, as well as the upper ends of the second side frame portion 22b2 and the third side frame portion 22b3, by inserting screws (not shown) through screw holes 26. Thus, the right side frame is formed by connecting the third upper frame portion 22a3 to the open end portion of the right side U-shaped portion 21b (the portion where the upper ends of the second side frame portion 22b2 and the third side frame portion 22b3 are separated from each other).

[0087] Thereafter, the left panel 24a, right panel 24b, upper panel 24c, lower panel 24d, front panel 24e, and rear panel 24f are attached to form the electronic device 100 including the plurality of modules 10 and the electronic device housing 20.

[0088] As described above, since the frame body 21 is partially welded except for the first upper frame portion 22a1 and the third upper frame portion 22a3, the deformation of the frame body 21 can be suppressed compared to the case where each frame portion 22 is screwed, and the strength can be improved. Thus, an electronic device device 100 can be provided that can accommodate and support heavy equipment components in the electronic device housing 20. In particular, the U-shaped portion 21a on the left side and the U-shaped portion 21b on the right side of the frame body 21 are joined by welding. Thus, compared to the case where each frame portion 22 is formed into a U-shaped portion by screwing, the deformation of the U-shaped portion can be suppressed, and the strength can be improved.

[0089] In addition, since the local U-shaped parts 21a and 21b of the frame body 21 are open at the top, it is easy to perform various tasks such as wiring connection, maintenance and inspection, such as wiring between modules 10 and wiring within the module 10, from the open side (upper part) of the U-shaped parts 21a and 21b when the module 10 is partially configured on the frame body 21.

[0090] Furthermore, by screwing the first upper frame portion 22a1 and the third upper frame portion 22a3 to the open ends of the U-shaped portions 21a and 21b, the frame body 21 is formed into a cubic shape. This cubic shape is preferred because it offers greater strength than a shape with oblique edges. Furthermore, this, in conjunction with the aforementioned partial welding of the frame body 21, can enhance the strength of the frame body 21.

[0091] Furthermore, as in the above-described structure, auxiliary frame portion 22d is used to connect the intermediate portions of the opposing frame portions 22 in the extending direction. This increases the number of connecting locations between opposing frame portions 22, compared to simply connecting the ends of opposing frame portions 22. Consequently, the strength of frame body 21 can be increased.

[0092] Furthermore, the plurality of cubic modules 10 are arranged inside the cubic frame 21 along the framework of the frame 21. Thus, the plurality of modules 10 and the frame 21 support each other, thereby increasing the strength of both.

[0093] It should be noted that, although the embodiments of the present invention have been disclosed in the above description, the present invention is not limited thereto. That is, various changes can be made to the above-described embodiments in terms of mechanism, shape, material, number, position, arrangement, etc. without departing from the scope of the technical concept and purpose of the present invention, and these modifications are also included in the present invention.

[0094] 3. Modifications About modules In the specific aspects of the above embodiments, Figure 4 The electronic device 100 shown in FIG. 1 includes four modules 10a to 10d. However, the number of modules 10 is not limited to this number and may be one or more and three or fewer, or five or more. Furthermore, while the structures and configurations of the various equipment components 30, 40, and the fan 50 are identical in the first and second modules 10a, 10b, the structures and configurations of the various equipment components may differ in each module 10. The shapes of the electronic device housing 20 and the electronic device 100 may also be modified accordingly based on the shapes and configurations of the modules 10.

[0095] Furthermore, the first and second modules 10a and 10b are equipped with electrolytic capacitors 35 and a pair of cooling fins 45, while the third module 10c is equipped with a transformer 36 and a pair of reactors 46. This allows the third module 10c, which includes the transformer 36, which generates more heat and weighs more, to be positioned at the bottom of the electronic device 100. However, the placement of the modules 10 is not limited to this. For example, the third module 10c, which includes the transformer 36 and a pair of reactors 46, can also be positioned at the top of the electronic device 100.

[0096] About equipment parts In the specific embodiment described above, an electrolytic capacitor 35 is used as one example of the first equipment component 30, and a transformer 36 is used as another example. However, the first equipment component 30 is not limited to these, and may be, for example, a resistor. Furthermore, in the specific embodiment described above, a cooling fin 45 is used as one example of the second equipment component 40, and a reactor 46 is used as another example. However, the second equipment component 40 is not limited to these.

[0097] For example, the second device unit 40 may also include electronic components 47 in addition to the cooling fins 45. In this case, when viewed from the ventilation direction perspective VDview, the electrolytic capacitor 35 is positioned above in the height direction x, and the combination of the upstream cooling fins 45u and the upstream electronic component 47a is positioned below. In this case, when viewed from the ventilation direction perspective VDview, the lower portion of the electrolytic capacitor 35 overlaps with the upper portion of the combination of the upstream cooling fins 45u and the upstream electronic component 47a in the height direction x, and the upper portion of the electrolytic capacitor 35 protrudes upward from the combination of the upstream cooling fins 45u and the upstream electronic component 47a. In other words, when viewed from the ventilation direction perspective VDview, the electrolytic capacitor 35 has an overlapping portion at its lower portion in the height direction x that partially overlaps with the combination of the upstream cooling fins 45u and the upstream electronic component 47a, and a protruding portion above the overlapping portion protrudes upward from the combination of the upstream cooling fins 45u and the upstream electronic component 47a. With this configuration, air from the first blower 50a is supplied to substantially the entire assembly of the upstream cooling fins 45u and the upstream electronic components 47a, and is also supplied to at least the protruding portion of the electrolytic capacitor 35. Furthermore, air supplied to the assembly of the upstream cooling fins 45u and the upstream electronic components 47a, along with the electrolytic capacitor 35, and then passing through the ventilation duct 53 is supplied to the assembly of the downstream cooling fins 45d and the downstream electronic components 47b. This allows the first blower 50a to efficiently cool the electrolytic capacitor 35, the pair of cooling fins 45, and the pair of electronic components 47. The positional relationship between the assembly of the upstream cooling fins 45u and the upstream electronic components 47a and the blower 50 is similar to that of the above-described embodiment.

[0098] Alternatively, the second equipment component 40 may include an upstream electronic component 47a and a downstream electronic component 47b instead of a pair of cooling fins 45. That is, the pair of electronic components 47 constitutes the second equipment component 40. In this case, the positional relationship between the upstream and downstream electronic components 47a, 47b and the electrolytic capacitor 35, and the positional relationship between the upstream and downstream electronic components 47a, 47b and the fan 50, etc., can be said to be the same as in the above-described embodiment.

[0099] In the specific embodiment described above, a combination of an electrolytic capacitor 35 and cooling fins 45, and a combination of a transformer 36 and a reactor 46 are used as the first equipment component 30 and the second equipment component 40. The combination of equipment components 30 and 40 is not limited to this, and the equipment components can be combined in various ways. For example, a transformer 36 and cooling fins 45 can be combined within a single module 10.

[0100] <C>About fans In the above embodiment, Figure 4 The electronic device 100 shown in FIG. 1 has first to third fans 50a to 50c disposed in the first to third modules 10a to 10c, respectively. The module 10 in which the fans 50 are disposed can be adjusted according to the types of equipment components disposed in the module 10. In addition, the number of fans 50 provided in each module 10 is not limited, and a plurality of fans 50 may be provided in each module 10. In addition, the size of the fan 50, the number of the rotary blades 52, etc. are not limited. Description of Reference Numerals
