  The electronic device of the first embodiment will be described in detail based on the drawings.

  As illustrated in FIG. 1, the electronic device 102 according to the first embodiment includes a housing 104. In the example illustrated in FIG. 1, the housing 104 is formed in a box shape. In the drawing, the upper side in the vertical direction of the housing 104, the right side in the width direction, and the back side in the depth direction are indicated by arrows U, R, and D, respectively. Further, the width direction of the housing 104 is indicated by an arrow W.

  The housing 104 has a component housing portion 106 located at the center in the vertical direction. Further, the housing 104 has a lower gap 108 and an air intake 110 on the lower side of the component accommodating portion 106, and an upper gap 112, a fan accommodating portion 114 and an exhaust portion 116 on the upper side of the component accommodating portion 106. Have. The space inside the upper gap 112 is an example of the gap 112G.

  In the present embodiment, a plurality of PIUs (plug-in units, plug-in-units) 118 are mounted in the component housing unit 106. Each of the PIUs 118 includes a board 120 and a mounting component 122 mounted on the board 120. Examples of the mounting component 122 include a main storage device, an integrated circuit such as a processor, various electronic elements, and the like. The PIU may be referred to as a plug-in card, a mountable card, an insertable card, an insertable / removable card, a line card, or the like.

  Each of the PIUs 118 is inserted into the component housing portion 106 in a direction in which the normal direction of the substrate 120 coincides with the width direction (arrow W direction) of the housing 104. The PIU 118 is an example of an electronic component.

  A connection board 172 is disposed on the inner side of the housing 104. In a state where the PIU 118 is mounted at a predetermined position of the component housing unit 106, the connector of each PIU 118 is connected to the connector of the connection board 172. Thereby, transmission / reception of signals between each PIU 118 and the connection board 172 and power supply from the connection board 172 to the PIU 118 are possible.

  As shown in FIG. 2, the component housing portion 106 is provided with a partition plate 124 extending in the vertical direction. The partition plate 124 partitions the component storage unit 106 into a PIU mounting unit 126 in which each of the PIUs 118 is stored. In other words, the corresponding PIU 118 is mounted on the PIU mounting section 126 partitioned by the partition plate 124 in the component housing section 106. The partition plate 124 may be provided in each of the PIUs 118, for example. In this case, in a state where the PIU 118 is mounted on the component storage unit 106, the component storage unit 106 is partitioned into a plurality of PIU mounting units 126 by the partition plates 124 provided on the PIU 118.

  As shown in FIG. 1, the intake section 110 has an intake port 128 that opens to the near side (the direction opposite to the arrow D). In the back of the intake port 128, an inclined wall 130 is provided that inclines upward toward the back side. As will be described later, the air that has flowed into the intake portion 110 from the intake port 128 by driving the fan unit 146 is guided upward by the inclined wall 130. Then, this air flows into the component housing portion 106 through the lower gap portion 108. The near side of the lower gap 108 is closed by a lower lid 132.

  As shown in FIG. 2, a filter 134 is provided in the lower gap 108. Foreign matter in the air flowing into the component housing portion 106 is removed by the filter 134.

  As shown in FIG. 1, the exhaust unit 116 has an exhaust port 136 that opens to the back side (in the direction of arrow D). In front of the exhaust port 136, an inclined wall 138 that is inclined upward toward the back side is provided. The air flowing into the exhaust part 116 from the component housing part 106 through the upper gap part 112 by driving the fan unit 146 is guided to the back side by the inclined wall 138. Then, this air is discharged from the exhaust port 136 to the outside of the housing 104. The front side of the upper gap 112 is closed by the upper lid 140.

  As shown in FIGS. 4A, 5A, and 6A, an upper plate 142 is provided on the upper portion of the fan accommodating portion 114, and the upper plate 142 has a plurality of ventilation holes 144 formed from the fan unit 146. The structure does not affect the wind transmission.

  As shown in FIGS. 2, 4A, 5A, and 6A, a plurality of fan units 146 are mounted in the fan accommodating portion 114 in a state of being arranged in the width direction (the arrow W direction in FIG. 2). In the example shown in FIG. 2, there are three fan units 146. The plurality of fan units 146 are opposed to the PIU 118. 4A, 5A and 6A, only one fan unit 146 is shown.

  As shown in FIG. 3, each fan unit 146 includes a housing 148 and one or a plurality of fan bodies 146B (not shown in FIG. 3, see FIG. 2) held in the holding recess 150 of the housing 148. Have. In one fan unit 146, two holding recesses 150 are formed side by side in the depth direction, and two fan main bodies 146B are also arranged side by side in the depth direction.

  The fan accommodating portion 114 is provided with a partition wall 152 extending in the vertical direction. By the partition wall 152, a fan mounting portion 154 on which each of the plurality of fan units 146 is mounted is formed in the fan housing portion 114. In the example shown in FIG. 2, three fan mounting portions 154 are formed in one-to-one correspondence with the fan units 146, and one of the fan units 146 corresponds to three of the PIU mounting portions 126.

  The opening on the front side of the fan mounting portion 154 is a fan insertion port 156. The fan unit 146 can be inserted into and removed from the fan mounting portion 154 through the fan insertion port 156 from the front side of the fan mounting portion 154 (insertion and removal). The insertion / extraction direction of the fan unit 146 is a direction orthogonal to the flow direction of the wind from the fan unit 146 (arrow F1 direction). In a state where the fan unit 146 is mounted at a predetermined position of the fan mounting portion 154, electric power is supplied from the connection board 172 through the power connector 146C provided in the fan unit 146. In the first embodiment, the electrical connection between the connection board 172 and the power connector 146C can be performed using a power cable or the like (not shown). As another example, the following can be considered. That is, a connector that fits with the power supply unit 146C is provided at an appropriate position on the connection board 172. Then, when the fan unit 146 is inserted, a method is also conceivable in which these connectors are fitted to supply power to the fan unit.

  A partition member 158 is accommodated in each fan mounting portion 154. As shown in FIG. 3, the partition member 158 includes a pair of partition plates 160 located on the left and right sides in the width direction in plan view (viewed from above), and a connecting plate 162 that connects the partition plates 160 on the back side. Have. The partition member 158 may be formed in a shape having a pair of partition plates 160 and a connecting plate 162 by bending a single metal plate material at two predetermined locations, or two separately molded plates. You may join the partition plate 160 and the one connection plate 162. FIG.

  The partition member 158 can slide up and down between a position stored in the fan mounting portion 154 (storage position CP, see FIG. 6B) and a position in the upper gap 112 (partition position DP, see FIG. 4B). is there. At the partition position DP, the partition member 158 partitions the space (gap 112G) inside the upper gap portion 112 at two locations in the width direction (arrow W direction). The partition member 158 is supported by a support member (not shown) of the housing 104 in the state at the partition position DP, and does not fall below the partition position DP.

  The height of the partition member 158 is higher than the height of the upper gap portion 112. In the partition member 158 of the first embodiment, the partition plate 160 and the connecting plate 162 have the same height. Therefore, in the state where the partition member 158 is at the partition position DP, the partition plate 160 reliably partitions the inside of the upper gap portion 112 (gap 112G) in the direction in which wind is generated. As described above, the partition member 158 higher than the upper gap portion 112 suppresses the movement of air in the gap 112G in the arrow W direction (left-right direction).

  The distance D1 between the pair of partition plates 160 is wider than the width W1 of the fan unit 146. Further, the front side of the partition member 158 is open. Therefore, the fan unit 146 can be inserted into and removed from the fan housing portion 114 from the front side of the partition member 158.

  In a state where the fan unit 146 is mounted on the fan mounting portion 154, the partition plate 160 is positioned between the side plate 164 of the fan unit 146 and the side plate 151 or the partition wall 152 of the housing 104.

  As shown in FIG. 3, an inclined plate 168 is provided on each inner surface (surface facing each other) of the pair of partition plates 160. The inclined plate 168 is inclined downward as it goes from the near side end of the partition plate 160 toward the far side end.

  The side plate 164 of the fan unit 146 is provided with support pins 170 that extend outward in the width direction. The support pin 170 supports the partition member 158 by contacting the lower surface of the inclined plate 168, and is an example of a support member.

  As shown in FIG. 6B, when the fan unit 146 is mounted on the fan mounting portion 154, the partition member 158 is inside the fan mounting portion 154 (fan housing portion 114), that is, in the storage position CP.

  As shown in FIG. 5B, the support pin 170 is in contact with the lower surface of the inclined plate 168 even when the fan unit 146 is being inserted into and removed from the fan mounting portion 154.

  As the fan unit 146 is removed from the fan accommodating portion 114, the support pin 170 moves to the near side, and the partition member 158 is lowered by gravity. And if the fan unit 146 is extracted from the fan mounting part 154 (fan accommodating part 114), the support pin 170 will separate from the inclination board 168, Therefore The partition member 158 is not supported. In this state, the partition member 158 moves downward due to gravity and is at the partition position DP.

  As described above, the inclined plate 168 is inclined downward as it goes from the front end of the partition plate 160 toward the back end. Therefore, when the fan unit 146 is moved to the back side with the support pin 170 in contact with the lower surface of the inclined plate 168, a part of the force acting on the inclined plate 168 from the support pin 170 to the back side is Converted to upward force. For this reason, the partition member 158 can be raised as the fan unit 146 is moved to the back side. When the fan unit 146 is accommodated in the fan mounting portion 154, the partition member 158 reaches the storage position CP.

  The partition member 158 is formed in such a width as to contact the partition wall 152 or to face the partition wall 152 with a predetermined slight gap. Thereby, when the partition member 158 moves between the storage position CP and the partition position DP, it is suppressed that the partition member 158 is inadvertently shifted or inclined in the width direction.

  Further, the front end portion of the partition member 158 (partition plate 160) comes into contact with a restriction portion (not shown) formed on the partition wall 152 or the upper lid 140, so that the partition member 158 is displaced from the fan housing portion 114 toward the front side. There is no such thing. The back side of the partition member 158 (connection plate 162) is brought into contact with a restriction portion (not shown) formed in the housing 104 so that the partition member 158 does not shift from the fan housing portion 114 to the back side.

  As a result, a structure is realized in which the partition member 158 can move up and down without inadvertently sliding or tilting in the width direction or depth direction. The friction between the partition member 158 and the target (the upper lid 140, the limiting portion, etc.) that contacts when the partition member 158 moves up and down in this way is lowered so as not to hinder the vertical movement of the partition member 158.

  Next, the operation and cooling method of this embodiment will be described.

  As shown in FIG. 7, when the plurality of fan units 146 are driven in a state where they are accommodated in the fan accommodating portions 114 (corresponding fan mounting portions 154), a low pressure region LA is generated on the upstream side of the fan units 146, and the downstream side A high pressure area HA is produced on the side.

  When compared with the air pressure around the electronic device 102 (for example, atmospheric pressure), the low pressure region LA is a region where the atmospheric pressure is low, and the high pressure region HA is a region where the atmospheric pressure is high. Such a high pressure area HA and a low pressure area LA occur, and the wind generated by the fan unit 146 passes through the outside of the housing 104 and reaches the intake port 128. Then, for example, as shown by an arrow F2 in FIG. 7, the air is sucked in by the air intake unit 110 and is exhausted by the exhaust unit 116 through the lower gap part 108, the component housing part 106 (PIU mounting part 126), and the upper gap part 112. Wind circulation occurs.

  In the state where all of the plurality of fan units 146 are driven, wind flows into the housing 104 from the air inlet 128 as indicated by an arrow F3 in FIG. 2, and further, as indicated by an arrow F4, the wind flows. Flows into the component housing portion 106, and the PIU 118 of the PIU mounting portion 126 can be cooled. Since this wind is a flow of outside air taken in from the intake section 110, for example, compared with the wind after cooling the PIU 118, the effect of cooling the electronic device 102 is high.

  In a state where the fan unit 146 is mounted on the fan accommodating portion 114, the support pins 170 are in contact with the lower surface of the inclined plate 168 on the back side of the inclined plate 168 as shown in FIG. 6B. Thereby, the support pin 170 which is an example of a support member supports the partition member 158. As shown in FIG. 6A, the partition member 158 is maintained at the storage position CP, and does not inadvertently move (lower) to the partition position DP.

  When the fan unit 146 is inspected or replaced, a part of the plurality of fan units 146 may be removed from the fan accommodating portion 114. It is desirable to ensure that the PIU 118 can be cooled even when some fans are removed from the fan accommodating portion 114.

  The electronic device 102 of the first embodiment has a partition member 158. For this reason, at the position between the fan mounting portion 154 with the fan removed (hereinafter referred to as space DS after removal) and the fan mounting portion 154 adjacent on both sides thereof, the inside of the upper gap portion 112 (gap 112G ) Can be partitioned. Specifically, as the fan unit 146 is removed from the fan housing portion 114, the partition member 158 descends due to gravity. The post-extraction space DS is an example of a first fan mounting portion.

  In the electronic device 102 of the first embodiment, when the fan unit 146 is removed from the fan housing portion 114, the support pins 170 are separated from the inclined plate 168. For this reason, the partition member 158 is not supported by the support pins 170 and reaches the partition position DP.

  As shown in FIG. 8, when the partition member 158 is in the partition position DP, the partition plate 160 partitions the inside of the upper gap portion 112 (gap 112G) into two regions 112A and 112B. The area 112A is an area below the space DS after removal. The region 112B is a region below the fan mounting portion 154 where the fan unit 146 is not removed on both sides of the space DS after removal.

  In this state, the fan unit 146 mounted on the fan accommodating portion 114 is driven. As indicated by an arrow F4 in FIG. 9, the fan unit 146 that has not been removed from the fan accommodating portion 114 generates wind in the PIU mounting portion 126 below the fan unit 146, so that the PIU 118 can be cooled.

  As shown by an arrow F5 in FIG. 9, a part of the wind generated by driving the fan unit 146 flows into the space DS after being extracted. In particular, as shown in FIG. 7, a low pressure region LA occurs on the upstream side of the wind generated by the fan unit 146, and a high pressure region HA occurs on the downstream side. By utilizing such an atmospheric pressure distribution, the wind generated using the fan unit 146 can be effectively guided by the partition member 158.

  The inside of the upper gap portion 112 (gap 112G) is partitioned into a plurality of regions 112A and 112B by a partition member 158, and the wind that has flowed into the region 112A does not flow directly from the region 112A to the region 112B. That is, it is possible to suppress the wind from flowing into the fan unit 146 without flowing through the PIU mounting portion 126.

  This wind flows through the PIU mounting portion 126 below the space DS after removal as indicated by an arrow F6. This wind flow is opposite to the wind flow (indicated by arrow F4) of the PIU mounting portion 126 below the fan unit 146. Thus, even when some of the fan units 146 are removed from the fan housing portion 114, the PIU 118 (electronic device) of the PIU mounting portion 126 corresponding to the space DS after removal can be effectively cooled.

  Below, the effect | action of the electronic device 102 of 1st embodiment is demonstrated in the comparison with the electronic device of a 1st comparative example and a 2nd comparative example.

  10 and 11 show the electronic devices 32 and 52 of the first comparative example and the second comparative example, respectively.

  The electronic device 32 of the first comparative example has a structure in which the upper gap portion 112 (see FIG. 2) is not provided between the component housing portion 106 and the fan housing portion 114 as in the first embodiment. Further, the electronic device 32 of the first comparative example has a structure without the partition member 158 (see FIGS. 2 and 3) as in the first embodiment.

  In the electronic device 32 of the first comparative example, it is assumed that the fan units 146 remaining in the fan housing portion 114 are driven in a state where some of the fan units 146 are removed from the fan housing portion 114. In this case, wind is generated in the PIU mounting 126 corresponding to the fan unit 146 as shown by the arrow F11, so that the PIU can be cooled. However, the wind generated in the PIU mounting portion 126 below the space DS after extraction is weak. In particular, if the interior of the component housing portion 106 is partitioned by the partition plate 124, the wind may not be substantially generated in the PIU mounting portion 126 below the space DS after the removal.

  In the electronic device 52 of the second comparative example, the fan accommodating portion 114 is not provided with the partition member 158 (see FIGS. 2 and 3) as in the first embodiment.

  In the electronic device 52 of the second comparative example, when the fan unit 146 remaining in the fan accommodating portion 114 is driven, wind is generated in the PIU mounting portion 126 corresponding to the fan unit 146 as indicated by the arrow F12. Can be cooled.

  However, in the electronic device 52 of the second comparative example, a part of the wind generated by the fan unit 146 flows into the space DS after being extracted, as indicated by an arrow F13. Further, this wind is sucked into the fan unit 146 through the upper gap portion 112 as indicated by an arrow F14. That is, a wind that circulates between the fan unit 146 and the space DS after removal is generated. For this reason, the amount of air that can be supplied to the PIU mounting portion 126 corresponding to the space DS after removal decreases, and it is difficult to send in sufficient air for cooling the electronic device 102.

  In order to suppress such wind circulation (arrow F14), for example, a shutter corresponding to each of the fan units 146 is provided in the upper gap portion 112 (between the fan mounting portion 154 and the component housing portion 106). A structure to be provided is conceivable.

  However, when the shutter is provided between the upper gap portion 112 and the fan accommodating portion 114 and the component accommodating portion 106, even if the shutter is fully opened, a plurality of blades of the shutter are located between the fan accommodating portion 114 and the component accommodating portion 106. Because of the presence of wind resistance.

  In the electronic device 102 of the first embodiment, compared to the electronic devices 32 and 62 of these comparative examples, the PIU 118 corresponding to the space DS after extraction can be effectively cooled with the fan unit 146 removed.

  The wind that has flown backward through some of the PIU mounting portions 126 flows through the PIU mounting portion 126 corresponding to the fan unit 146 from the lower gap portion 108 as shown by an arrow F7 in FIG.

  Since the lower gap portion 108 is provided with the filter 134, foreign substances in the air flowing into the component housing portion 106 from the outside of the housing 104 can be removed.

  This filter acts as a resistance when the wind that has flowed inside the housing 104 as indicated by the arrow F6 goes out. Thereby, the flow of the wind (indicated by the arrow F7) circulating inside the housing 104 can be promoted.

  The housing 104 is provided with a partition plate 124 that partitions the interior of the component housing portion 106 into a plurality of PIU mounting portions 126. Thereby, since the wind flowing through the PIU mounting portion 126 does not mix inadvertently in the width direction, it is possible to maintain the flow of the wind in each region partitioned by the partition plate 124 and effectively cool each PIU 118. .

  When the removed fan unit 146 is inserted into the fan accommodating portion 114 (fan mounting portion 154), the support pin 170 comes into contact with the lower surface of the inclined plate 168 at the initial stage of insertion, as shown in FIG. 4B. Since the inclined plate 168 is inclined downward as it goes from the near side to the deep side, when the fan unit 146 is moved to the deep side, a part of the backward force acting on the inclined plate 168 from the support pin 170 is obtained. Is converted into a force that moves the partition member 158 upward. Therefore, the partition member 158 can be raised against gravity by moving the fan unit 146 further back.

  And if the fan unit 146 is mounted in the predetermined position of the fan accommodating part 114, the partition member 158 will reach the storing position CP. Since the support pin 170 is in contact with the lower surface of the inclined plate 168 in a state where the partition member 158 is at the storage position CP, the partition member 158 is supported by the support pin 170 and does not descend.

  Next, a second embodiment will be described. In the second embodiment, the overall structure of the electronic device is the same as that of the first embodiment, and thus illustration is omitted. Moreover, in 2nd embodiment, the same code | symbol is attached | subjected about the same element, member, etc. as 1st embodiment, and detailed description is abbreviate | omitted.

  As illustrated in FIG. 12, the electronic device 202 according to the second embodiment includes a rotating plate 204. The rotating plate 204 is an example of a rotating member. The rotating plate 204 has a one-to-one correspondence with the fan mounting portion 154 and is rotatably attached to the housing 104 by a support shaft 206 provided on the upper portion. The position of the support shaft 206 is above the moving area of the fan unit 146 inserted into and removed from the fan mounting portion 154.

  In a state where the fan unit 146 is removed from the fan mounting portion 154, the rotating plate 204 takes a substantially vertical posture by gravity and covers the fan insertion port 156 as shown in FIGS. 13A and 13B. When the fan unit 146 is inserted into the fan mounting portion 154, as shown in FIGS. 14A and 14B, the rotating plate 204 is pushed and rotated by the fan unit 146 in the middle of insertion, and the lower end is circular toward the back side and the upper side. Displaces in an arc. As shown in FIGS. 15A and 15B, the rotation plate 204 further approaches a horizontal posture as the fan unit 146 is inserted. When the fan unit 146 reaches a predetermined position of the fan mounting portion 154, the rotating plate 204 takes a substantially horizontal posture as shown in FIGS. 16A and 16B.

  A pair of receiving pins 208 protrudes from the left and right at the bottom of the rotating plate 204. The pair of partition plates 160 of the partition member 158 are formed with elongated holes 210 that extend in the depth direction and each accommodate the accommodation pin 208.

  The position and length of the long hole 210 are such that the partition member 158 is in the retracted position CP when the rotating plate 204 is in a substantially horizontal posture, and the partition member 158 is in the partitioning position when the rotating plate 204 is in a substantially vertical posture. It is set to be in DP.

  In the electronic device 202 of the second embodiment, as shown in FIGS. 13A and 13B, the tip of the fan unit 146 hits the rotating plate 204 while the fan unit 146 is being inserted into the fan mounting portion 154.

  As shown in FIGS. 14A and 14B, when the fan unit 146 is moved to the back side, the rotating plate 204 is pushed by the fan unit 146 and rotates in the direction of the arrow R1, and the receiving pin 208 is formed in an arc shape obliquely upward. Moving. Since the accommodation pin 208 is accommodated in the long hole 210 of the partition member 158, the partition member 158 also rises as the accommodation pin 208 rises. As shown in FIGS. 15A and 15B, when the fan unit 146 is further moved to the back side, the partition member 158 further rises accordingly.

  Then, as shown in FIGS. 16A and 16B, the partition member 158 reaches the storage position CP when the rotating plate 204 is in a substantially horizontal posture. In this state, the tip of the fan unit 146 is separated from the rotating plate 204, so that the fan unit 146 can be further moved to the back side and mounted on the fan mounting portion 154.

  When the fan unit 146 is removed from the fan mounting portion 154, the rotating plate 204 rotates in the direction opposite to the arrow R1 while moving the fan unit 146 to the near side. Since the accommodation pin 208 descends in an arc shape, the partition member 158 also descends. When the fan unit 146 is removed from the fan mounting portion 154, the partition member 158 reaches the partition position DP.

  As described above, the electronic device 202 according to the second embodiment has a structure in which the accommodation pin 208 provided in the rotating plate 204 is accommodated in the long hole 210 provided in the partition member 158. Thereby, the partition member 158 can be moved up and down as the fan unit 146 is inserted and removed.

  In the electronic device 202 of the second embodiment, the rotating plate 204 covers the fan insertion port 156 in a state where the fan unit 146 is removed from the fan mounting portion 154. For this reason, it can suppress that a foreign material mixes into the fan mounting part 154 from the fan insertion port 156 compared with the structure where the fan insertion port 156 is open | released.

  In order for the rotating plate 204 to cover the fan insertion port 156 and prevent foreign matter from entering, the rotating plate 204 is not limited to a structure that covers the entire opening cross section of the fan insertion port 156, and the opening of the fan insertion port 156 is not limited. The structure which covers a part of part may be sufficient.

  In the second embodiment, the rotating member is not limited to the rotating plate 204. For example, a rod-shaped member having the support shaft 206 and the accommodation pin 208 may be used. Such a rod-shaped rotating member has a small area covering the opening cross section of the fan insertion port 156, but is lighter than a plate-shaped rotating member (rotating plate 204).

  Next, a third embodiment will be described. In the third embodiment, the entire structure of the electronic device is the same as that of the first embodiment, and thus illustration is omitted. Moreover, in 2nd embodiment, the same code | symbol is attached | subjected about the same element, member, etc. as 1st embodiment or 2nd embodiment, and detailed description is abbreviate | omitted.

  As illustrated in FIG. 17, the electronic device 302 of the third embodiment includes a rotating plate 304. Similar to the rotating plate 204 of the second embodiment, the rotating plate 304 is rotatably attached to the housing 104 by a support shaft 206. In addition, a pair of accommodation pins 208 on the left and right are respectively accommodated in the long holes 210 of the partition member 158.

  A recess 306 is formed in the rotating plate 304. The recess 306 is an example of a notch formed in the rotating member (the rotating plate 304). Since the concave portion 306 is formed, as shown in FIG. 18, the rotating plate 304 is in a substantially horizontal posture and avoids the passage of the wind from the fan main body 146B.

  Therefore, in the electronic device 302 of the third embodiment, the rotating plate 304 is in a substantially horizontal posture, and the rotating plate 304 becomes a resistance against the wind coming from the fan main body even if the rotating plate 304 is positioned above the fan unit 146. It is suppressed.

  The size of the concave portion 306 can be set by a balance between the effect that the rotating plate 304 covers the fan insertion port 156 and suppresses the entry of foreign matter, and the effect of avoiding the air passage from the fan unit 146 on the upper side of the fan unit 146. Further, the notch formed in the rotating plate 306 is not limited to the fan recess 306, and may be, for example, a through-hole penetrating the rotating plate 306 in the thickness direction.

  Next, a fourth embodiment will be described. In 4th embodiment, since the whole structure of an electronic device is the same as that of 1st embodiment, illustration is abbreviate | omitted. Moreover, in 4th embodiment, the same code | symbol is attached | subjected about the same element, member, etc. as 1st embodiment, and detailed description is abbreviate | omitted.

  As shown in FIG. 19, in the electronic device 402 of the fourth embodiment, an insertion hole 404 is formed in the connecting plate 162 of the partition member 158. A power connector 146 </ b> C is provided on the rear surface of the housing 148 of the fan unit 146. By connecting the power connector 146 </ b> C of the fan unit 146 to the connector of the connection board 172, the fan unit 146 can receive power supply from the connection board 172.

  The insertion hole 404 is formed in a position and shape that avoids the power connector 146 </ b> C of the fan unit 146 when the fan unit 146 is being inserted into the fan mounting portion 154 and in the inserted (mounted) state. In the example shown in FIG. 19, the insertion hole 404 is formed at the center in the width direction of the connecting plate 162 and has a shape that opens downward.

  When the partition member 158 is raised by the operation of inserting the fan unit 146 into the fan mounting portion 154, the connecting plate 162 is positioned between the housing 148 of the fan unit 146 and the connection board 172. In the electronic device 402 of the fourth embodiment, the power connector 146C of the fan unit 146 can be connected to the connector of the connection board 172 even if the connecting plate 162 is positioned between the housing 148 and the connection board 172 as described above. Since the connectors can be connected by the operation of mounting the fan unit 146 on the fan mounting portion 154, connection work such as a cable for supplying power to the fan unit 146 is unnecessary.

  In addition, as shown in FIG. 20, it is also possible to take the structure of a modification in 4th embodiment. In the electronic device 408 of this modification, a bent portion 410 is formed at the center in the width direction of the connecting plate 162. The bending portion 410 is formed by partially bending the plate material of the connecting plate 162 so that the connecting plate 162 is partially recessed toward the near side when viewed from the back (in the direction opposite to the arrow D). Yes.

  The connector of the connection board 172 may protrude forward from the connection board 172. For example, when the gap between the connection board 172 and the connecting plate 162 is narrow, the connector of the connection board 172 is raised while the partition member 158 is raised. It is conceivable that the connecting plate 162 hits. On the other hand, in the structure of the modified example of the fourth embodiment, a connector can be avoided by the bent portion 410. In other words, even if the gap between the connection board 172 and the connection plate 162 is narrow, the partition member 158 can be raised without bringing the connection plate 162 into contact with the connector of the connection board 172.

  In the fourth embodiment, the structure in which the partition member 158 is moved up and down in accordance with the insertion / extraction of the fan unit 146 with respect to the fan mounting portion 154 can adopt any structure of the first to third embodiments.

  In the first to fourth embodiments, the structure of the first modification shown in FIGS. 21 and 22 and the structure of the second modification shown in FIG. 23 can be adopted. In the first modification and the second modification, the partition member 158 is provided with the inclined plate 168 or the long hole 210, but these are not shown in FIGS. Also, the fan unit 146 is not shown in FIGS.

  In the first modified example, one or a plurality of protrusions 512 extending in the vertical direction are formed on the outer surfaces of the partition plate 160 and the connection plate 162. On the other hand, rails 514 into which the protrusions 512 are fitted are provided on the side walls 114S and the back walls 114D of the fan housing part 114 in a one-to-one correspondence with the protrusions 512. The rail 514 also extends in the vertical direction, and the partitioning member 158 is guided so as to slide smoothly in the vertical direction as the protrusion 512 moves in the rail 514. However, the movement of the partition member 158 in the width direction and the depth direction is limited, and the protrusion 512 and the rail 514 are examples of the limit member.

  Thus, by providing the limiting member, when the partition member 158 moves between the storage position CP and the partition position DP, the movement in the width direction and the depth direction can be limited. For this reason, the vertical movement of the partition member 158 between the storage position CP and the partition position DP is possible.

  In the second modification, a roller 612 is provided in the vertical direction instead of the protrusion 512 of the first modification. A plurality of rollers 612 are provided per rail 514 at a position where the rollers 612 are fitted (three in the example of FIG. 23 with an interval in the vertical direction). In the second modification, the rail 514 and the roller 612 are an example of a limiting member.

  Therefore, also in the third embodiment, when the partition member 158 moves between the storage position CP and the partition position DP, the movement in the width direction and the depth direction can be restricted, and the space between the storage position CP and the partition position DP can be limited. Smooth vertical movement is possible. In particular, in the third embodiment, since the roller 612 rotates, the resistance in the vertical movement of the partition member 158 is small.

  In each of the above embodiments, the partition member 158 includes the partition plate 160. When the partition member 158 is in the storage position CP, the partition plate 160 is positioned between the plurality of fan mounting portions 154. Therefore, the upper gap portion 112 can be easily partitioned by the partition plate 160 by the partition member 158 moving to the partition position DP. Since the partition plate 160 is a plate-shaped portion, the upper gap portion 112 can be partitioned with a simple structure. Further, by reducing the plate thickness (thickness in the width direction) of the partition plate 160, a wide cross-sectional area of the flow path of the wind (see arrow F6 in FIG. 9) flowing through the upper gap 112 can be secured.

  The partition plate 160 is provided in the partition member 158 on the left and right in the width direction, that is, in the insertion direction of the fan unit 146. These two partition plates 158 may be separate from each other, but in the structure of each of the above embodiments, the two partition plates 160 are connected by the connecting plate 162. That is, the pair (two sheets) of the partition plates 160 can be moved up and down by the operation of the partition member 158 moving (up and down) between the storage position CP and the partition position DP.

  The fan unit 146 is inserted into and removed from the fan mounting portion 154 in a direction orthogonal to the blowing direction, but the connecting plate 162 is located on the back side when viewed in the insertion direction of the fan unit 146. As a result, the connecting plate 162 does not overlap the range through which the wind sent from the fan unit 146 passes, so that the connecting plate 162 does not act on the wind flow.

  In each of the above embodiments, the fan mounting portion 154 is provided above the PIU 118 (electronic component), and the upper gap portion 112 is located between the PIU 118 and the fan unit 146. Therefore, the partition member 158 faces downward from the storage position CP (position in the fan mounting portion 154) to the partition position (position in the upper gap portion 112), and gravity can be used for this movement. That is, there is no need to provide a member for applying a force for moving the partition member 158 from the storage position CP to the partition position DP.

  On the contrary, for example, when a fan mounting portion is provided between the air intake portion 110 and the lower gap portion 108 in FIG. 2 and the fan is removed from the fan mounting portion, the partition member is moved from the fan mounting portion to the lower gap portion. A sliding structure may be used. In this structure, in order to slide the partition member from the fan mounting portion to the lower gap portion against gravity, an upward force may be applied to the partition member by a spring or the like, for example.

  Further, the structure is not limited to a structure in which the partition member is moved from the storage position CP to the partition position DP using gravity, spring force, or the like. For example, the partition member may be moved from the storage position CP to the partition position DP by manual operation.

  As described above, the electronic device of the present application includes, for example, an electronic device having a structure in which a repeater (transponder), a storage device (storage), and the like are mounted in addition to the structure in which the PIU 118 is mounted.

  The embodiments of the technology disclosed in the present application have been described above. However, the technology disclosed in the present application is not limited to the above, and can be variously modified and implemented in a range not departing from the gist of the present invention.
