Embodiments of the present invention will be described below.
Embodiment 1 of the Invention

  1 to 3 show a first embodiment of the present invention. In the first embodiment, the ISO standard container 2 is used as an example of the casing, and the heat exchanger 17 is used as an example of the heat exchange means. In FIG. 1, illustration of the electronic device 12 is omitted.

  The electronic device housing apparatus 1 according to the first embodiment includes a rectangular parallelepiped ISO standard container 2 as shown in FIG. This ISO standard container 2 is composed of a ceiling 4, a floor 5, a pair of left and right side walls 6, 7 and a pair of front and rear end walls 8, 9, and these ceiling 4, floor 5, side walls 6, 7 and end wall. A sealed space S <b> 1 is formed so as to be surrounded by 8 and 9. And the ISO standard container 2 is equipped with the heat insulation structure which insulates the inside and outside of this sealed space S1. The rear end wall 9 is openable and closable.

  Further, inside the ISO standard container 2, as shown in FIGS. 1 and 2, a plurality of racks 11 having a rectangular parallelepiped (rectangular cross section) are provided in the center of the ISO standard container 2 in the horizontal direction (arrow Y direction) (for example, 8), and are installed in a welded form along the front-rear direction (arrow X direction) of the ISO standard container 2 with no gap therebetween. The internal space of the ISO standard container 2 is divided into two intake areas A1 and A2 by these racks 11.

  2 and 3, each rack 11 includes a plurality of pairs (for example, 40 pairs) of flat (thin rectangular parallelepiped) electronic devices 12 such as servers, routers, communication devices, and storages. 11 is inserted from the front surface (lower side surface in FIG. 2) and rear surface (upper side surface in FIG. 2), and is stored in a stacked manner along the vertical direction (arrow Z direction) of the ISO standard container 2. These electronic devices 12 have a front surface 12a serving as an intake surface of the electronic device 12 located on the front side of the rack 11 in contact with one intake area A1, and an intake surface of the electronic device 12 located on the rear side of the rack 11. The front surface 12a is in contact with the other intake area A2. Further, an exhaust chimney 3 is formed in the vertical direction so as to be sandwiched between the back surfaces 12b serving as exhaust surfaces of the plurality of pairs of electronic devices 12.

  Further, as shown in FIG. 3, each rack 11 uses heat from the outside air to exchange heat in the exhaust chimney 3 to supply cold air to the two intake areas A1 and A2, as shown in FIG. Is equipped.

  Since the electronic device housing apparatus 1 has the above-described configuration, when the electronic device 12 is used in the electronic device housing apparatus 1, the temperature of the electronic device 12 rises. At this time, the electronic device 12 takes in cold air from each of the intake areas A1 and A2 and discharges hot air to the exhaust chimney 3 as shown in FIG. Further, the heat exchanger 17 exchanges hot air in the exhaust chimney 3 to supply cold air to the intake areas A1 and A2. Therefore, the electronic device 12 can be used normally within a specified operating temperature range because the temperature rise associated with its use is efficiently suppressed.

  At this time, as described above, the heat exchanger 17 is provided on a one-to-one basis for each rack 11, so even if a plurality of pairs of racks 11 are installed in the ISO standard container 2, the electronic equipment is in units of the rack 11. Twelve exhaust heat treatments can be performed. As a result, it becomes easy to properly perform the cooling of the heat generated by the electronic device 12.

  Further, in the electronic device housing apparatus 1, as described above, since a plurality of pairs of electronic devices 12 are housed in each rack 11, it is possible to increase the capacity of the entire electronic device housing device 1.

  In addition, as described above, the ISO standard container 2 includes a heat insulating structure that insulates the inside and outside of the sealed space S1, and therefore the operation of the electronic device 12 in the sealed space S1 regardless of the external temperature of the sealed space S1. Can be guaranteed. At the same time, even if the outside temperature of the sealed space S1 is low, it is possible to avoid the occurrence of a situation where condensation occurs inside the sealed space S1. Therefore, the electronic device housing apparatus 1 has a wide allowable temperature range at the place of installation, and thus is highly versatile.

Further, in the electronic device housing apparatus 1, all electronic devices 12, racks 11 and other members are housed in an ISO standard container 2, and this ISO standard container 2 is a kind of cargo container. Therefore, it becomes easy to install the electronic device accommodating apparatus 1 in a desired place by transporting the ISO standard container 2 together using a transportation means such as a vehicle or a ship. Moreover, when the electronic device housing apparatus 1 is used up, the electronic device housing apparatus 1 can be easily removed.
[Embodiment 2 of the Invention]

  4 to 6 show a second embodiment of the present invention. In the second embodiment, as in the first embodiment, the ISO standard container 2 is used as an example of the casing, the heat exchanger 17 is used as an example of the heat exchange means, and the blower fan 21 is used as an example of the blower means. The controller 23 is used as an example of the air blowing control means.

  In the electronic device housing apparatus 1 according to the second embodiment, as shown in FIG. 4, a single-sided rack 11A and a double-sided rack 11B are mixed.

  Here, as shown in FIG. 5, the single-sided rack 11 </ b> A is located slightly to the left of the center in the left-right direction (arrow Y direction) of the ISO standard container 2. Each rack 11A has a plurality (for example, 40) of flat (thin rectangular parallelepiped) electronic devices 12 such as servers, routers, communication devices, and storages, and is inserted into the rack 11A from the front (right side in FIG. 5). As a result, the ISO standard containers 2 are accommodated in a stacked form along the vertical direction (arrow Z direction). The front surface 12a of each rack 11A is in contact with the intake area A1, and the exhaust chimney 3 is formed in the vertical direction on the back surface 12b of each rack 11A.

  On the other hand, the double-sided rack 11B has a configuration similar to that of the first embodiment, as shown in FIG. Further, a rectangular tube-shaped vent pipe 20 is disposed at the lower part of each rack 11B so as to communicate between the two intake areas A1 and A2. The blower fan 21 is attached so as to be rotatable forward and backward. Further, pressure sensors 22 are attached to the two intake areas A1 and A2, respectively, and a controller 23 that drives a pair of blower fans 21 based on output signals of these pressure sensors 22 is provided.

  Further, as shown in FIG. 4, a partition plate 24 such as a curtain that shields the intake area A2 and the exhaust chimney 3 is provided between the single-sided rack 11A and the double-sided rack 11B so as to be openable and closable. It has been.

  Since other configurations are the same as those of the first embodiment, the same members are denoted by the same reference numerals and the description thereof is omitted.

  Therefore, in the second embodiment, the same function and effect as in the first embodiment described above are achieved.

  That is, when the electronic device 12 is used in the electronic device housing apparatus 1, the temperature of the electronic device 12 rises. At this time, in the single-sided rack 11 </ b> A, the electronic device 12 takes in cold air from the intake area A <b> 1 and discharges hot air to the exhaust chimney 3 as shown in FIG. 5. Further, the heat exchanger 17 exchanges hot air in the exhaust chimney 3 by using outside air to supply cold air to the intake area A1. Therefore, the electronic device 12 can be used normally within a specified operating temperature range because the temperature rise associated with its use is efficiently suppressed. On the other hand, in the double-sided rack 11B, the electronic device 12 takes in cold air from each of the intake areas A1 and A2 and discharges hot air to the exhaust chimney 3 as shown in FIG. Further, the heat exchanger 17 exchanges hot air in the exhaust chimney 3 to supply cold air to the intake areas A1 and A2. Therefore, the electronic device 12 can be used normally within a specified operating temperature range because the temperature rise associated with its use is efficiently suppressed.

  Thus, since the heat exchanger 17 is provided for each rack 11 on a one-to-one basis, even if a plurality of racks 11 are installed in the ISO standard container 2, the heat treatment of the electronic device 12 is performed in units of the racks 11. It can be performed. As a result, even when two types of racks with different accommodation methods for the electronic device 12 (that is, the single-sided rack 11A and the double-sided rack 11B) coexist, the heat generated by the electronic device 12 is properly cooled. Easy to implement.

  Other functions and effects are the same as those in the first embodiment.

  In addition to this, in the second embodiment, when there is a difference in air pressure between the two intake areas A1 and A2 during use of the electronic device 12, the controller 23 detects the pressure sensor attached to each of the intake areas A1 and A2. Based on the 22 output signals, the differential pressure between the two intake areas A1, A2 is calculated, and the pair of blower fans 21 are appropriately driven based on the differential pressure. At this time, when calculating the differential pressure between the two intake areas A1, A2, including the sign of plus / minus (positive / negative), the intake area A2 on the low pressure side from the intake area A1 or A2 on the high pressure side is calculated. Alternatively, the rotational direction (forward or reverse) of the blower fan 21 is determined so that the air is sent to A1.

  Specifically, for example, two levels of negative threshold values (from the smallest value, the first threshold value V1, the second threshold value V2) and two levels of positive threshold values (from the smaller value, the third value Threshold value V3, fourth threshold value V4) is set in advance, and when the differential pressure between the two intake areas A1, A2 is less than the first threshold value V1, the differential pressure is large. When the blower fan 21 is reversely rotated at a high speed and the differential pressure is equal to or higher than the first threshold value V1 and lower than the second threshold value V2, the differential fan pressure is present even though the differential pressure is small. Reverse with. Further, when the differential pressure is equal to or higher than the second threshold value V2 and lower than the third threshold value V3, it is considered that the differential pressure is negligibly small, so the blower fan 21 is not driven. Further, when this differential pressure is not less than the third threshold value V3 and less than the fourth threshold value V4, this differential pressure exists even though it is small. Is greater than or equal to the fourth threshold value V4, the differential pressure is large, so the blower fan 21 is rotated forward at high speed.

  As a result, even if there is a difference in air pressure between the two intake areas A1 and A2 due to some cause, the difference is quickly eliminated. Therefore, since all the electronic devices 12 can be cooled almost uniformly, these electronic devices 12 can be used in the best condition.

Further, as described above, the partition plate 24 that shields the intake area A2 and the exhaust chimney 3 is provided between the single-sided rack 11A and the double-sided rack 11B. It is possible to avoid a situation where the heat exchange efficiency decreases due to contact with the exhaust chimney 3. In addition, since the partition plate 24 can be opened and closed, when handling the electronic device 12 accommodated in each of the racks 11A and 11B for inspection and maintenance, it does not hinder the operator who passes through the intake area A2. .

Heat exchange is performed to supply cold air to the two intake areas A1 and A2.

  That is, a plurality of pairs of electronic devices 12 are accommodated in the rack 11 so as to be stacked, and two ducts 26 are formed on both sides of these electronic devices 12 in the vertical direction. Further, as shown in FIG. 7, an underfloor air conditioner 25 is provided below the rack 11 so as to supply cold air to the two ducts 26.

  In addition, as shown in FIGS. 9 and 10, a pair of left and right (for example, 40 pairs of left and right) C-shaped guide rails 27 corresponding to the electronic device 12 are stacked in the rack 11 in the vertical direction without gaps. Each electronic device 12 is in a state of being accommodated in the rack 11 by engaging the locking portions 12 d protruding from the left and right side surfaces of the substantially rectangular parallelepiped device body 12 c with the C-shaped guide rail 27. When a plurality of pairs of electronic devices 12 are accommodated in these C-shaped guide rails 27, four side walls of the exhaust chimney 3 are configured by the back surface 12 b of these electronic devices 12 and the C-shaped guide rails 27.

  About another structure, it is the same as that of Embodiment 1 mentioned above. Therefore, the third embodiment has the same operational effects as the first embodiment described above.

In addition, in the third embodiment, as described above, heat exchange is performed using the underfloor air conditioning instead of the outside air, so that the heat generated by the electronic device 12 is appropriately cooled without being affected by the level of the outside air temperature. be able to. Therefore, it becomes possible to install and use the electronic device housing apparatus 1 even in an area where the outside air temperature is high, and the versatility of the electronic device housing apparatus 1 is improved.
