  As shown in FIG. 1A and FIG. 1B, the rack body 200 is constituted by a rectangular parallelepiped housing. The inside of the rack body 200 is hollow and is provided so that a plurality of storage chambers 100 are stacked. The rack body 200 includes a front door 210, a midpiece 220, and a rear door 230. The front door 210 and the rear door 230 are attached to the midpiece 220.

  As shown in FIG. 1A and FIG. 1B, the air inlet 300 is provided on the front side (front door 210 side) of each storage chamber 100 of the rack body 200. The air inlet 300 sucks air outside the rack body 200.

  As shown in FIG. 1A, the exhaust port 400 is provided on the back side (rear door 230 side) of each storage chamber 100 of the rack body 200. The exhaust port 400 discharges the air sucked from the intake port 300 to the outside of the storage chamber 100 on the back side of each of the storage chambers 100.

  As shown in FIGS. 1A and 1B, the intake side temperature sensor 500 is provided on the front side of each storage chamber 100 of the rack body 200. The intake side temperature sensor 500 measures the intake air temperature, which is the temperature of the air drawn from the intake port 300. In FIG. 1A and FIG. 1B, the intake side temperature sensor 500 is described as “sensor” because of the description space in the drawing.

  As shown in FIG. 1A, the exhaust side temperature sensor 600 is provided on the back side of each storage chamber 100 of the rack body 200. The exhaust side temperature sensor 600 measures the exhaust temperature, which is the temperature of the air discharged to the exhaust port 400. In FIGS. 1A and 1B, the exhaust-side temperature sensor 600 is expressed as “sensor” because of the description space in the drawing.

  As shown in FIG. 1A and FIG. 1B, the intake opening ratio control unit 700 is provided on the front side of each storage chamber 100 of the rack body 200. However, the intake opening ratio control unit 700 may be provided at a location other than the front side of each accommodation chamber 100 as long as it is provided for each accommodation chamber 100. Each intake opening ratio control unit 700 controls the opening ratio of the intake port 300 for each storage chamber 100. At this time, the intake opening ratio control unit 700 sets the filter 800 described later to the intake port based on the difference value between the exhaust temperature measured by the exhaust side temperature sensor 600 and the intake temperature measured by the intake side temperature sensor 500. By installing in 300, the aperture ratio of the inlet 300 is controlled.

  As shown in FIG. 1A and FIG. 1B, the filter 800 is provided on the front side of each storage chamber 100 of the rack body 200. The filter 800 is preset to a predetermined aperture ratio.

  Here, the configuration of the filter 800 will be described in detail. FIG. 2 is an enlarged view showing a detailed configuration of the filter 800. FIG. 2A shows an example in which the aperture ratio of the filter 800 is set high. FIG. 2B shows an example in which the aperture ratio of the filter 800 is set low.

  As shown in FIGS. 2A and 2B, the filter 800 includes a first opening panel 810 and a second opening panel 820. The first opening panel 810 and the second opening panel 820 are arranged to overlap each other. At this time, the first opening panel 810 is fixed to the air inlet 300. On the other hand, the second opening panel 820 is held in the storage chamber 100 so that it can move in a direction substantially parallel to the surface of the first opening panel 810 by the power of the panel driving unit 900 described later. Here, it has been described that the first opening panel 810 is fixed to the air inlet 300 and the second opening panel 820 is movably held in the storage chamber 100. On the other hand, the second opening panel 810 may be fixed to the air inlet 300, and the first opening panel 820 may be movably held in the storage chamber 100.

  The first panel 810 includes a plurality of first through holes 811 arranged at a predetermined interval. Similarly, the second opening panel 820 includes a plurality of second through holes 821 arranged at a predetermined interval. At this time, the first through hole 811 and the second through hole 821 have the same shape and the same size. The interval between the first through holes 811 adjacent to each other and the interval between the second through holes 821 adjacent to each other are set to be the same.

  Next, a case where the aperture ratio of the filter 800 is changed will be described.

  First, an example in which the aperture ratio of the filter 800 is set high will be described with reference to FIG. As shown in FIG. 2A, when the aperture ratio of the filter 800 is set high, the first opening panel 810 and the second opening panel 820 include the first through-hole 811 and the second through-hole 821. Are placed so that they are completely opposite each other. Thereby, the aperture ratio of the filter 800 can be set high. Here, the aperture ratio is 80%.

  Next, an example in which the aperture ratio of the filter 800 is set low will be described with reference to FIG. As shown in FIG. 2B, when the aperture ratio of the filter 800 is set low, the first opening panel 810 and the second panel 820 have the first through hole 811 and the second through hole 821. They are stacked so that they are placed completely opposite each other. That is, the first through-hole 811 and the second through-hole 821 are shifted from each other on the surfaces of the first opening panel 810 and the second opening panel 820. Thereby, the aperture ratio of the filter 800 can be set lower than the example of FIG. Here, the aperture ratio is set to 60%.

  Next, the configuration of the control system of the electronic device housing rack 1000 will be described. FIG. 3 is a block diagram illustrating a configuration of a control system of the electronic device housing rack 1000.

  As shown in FIG. 3, the control system of the electronic device housing rack 1000 includes an intake side sensor 500, an exhaust side sensor 600, an intake opening ratio control unit 700, a filter 800, and a panel drive unit 900. Composed.

  As shown in FIG. 3, the intake side sensor 500 and the exhaust side sensor 600 are connected to an intake opening ratio control unit 700. Also, an intake opening ratio control unit 700 and a panel drive unit 900 are connected.

  At this time, the intake opening ratio control unit 700 calculates a difference value between the exhaust temperature measured by the exhaust side temperature sensor 600 and the intake air temperature measured by the intake side temperature sensor 500. Thereby, the temperature that rises due to heat dissipation of the electronic device 10 is calculated.

  Then, the intake opening ratio control unit 700 is configured such that the first opening panel 810 and the second opening panel 820 are relative to the panel driving unit 700 based on the measured value of the difference value between the exhaust temperature and the intake temperature. A command signal for changing the position is output. At this time, a predetermined threshold is set for the difference value between the exhaust gas temperature and the intake air temperature.

  When the difference measurement value between the exhaust temperature and the intake air temperature is larger than the threshold value, the intake opening ratio control unit 700 performs panel driving on a command signal for moving the second opening panel 820 so that the opening ratio of the intake port 300 increases. Output to the unit 700. More specifically, as shown in FIG. 2A, the intake opening ratio control unit 700 is arranged so that the first through hole 811 and the second through hole 821 are completely opposed to each other. A command signal for moving the second opening panel 820 is output to the panel driving unit 700.

  On the other hand, when the difference measurement value of the exhaust temperature and the intake air temperature is smaller than the threshold value, the intake opening ratio control unit 700 sends a command signal for moving the second opening panel 820 so that the opening ratio of the intake port 300 becomes small. Output to the panel drive unit 700. More specifically, as shown in FIG. 2B, the intake opening ratio control unit 700 is arranged so that the first through hole 811 and the second through hole 821 do not completely face each other. A command signal for moving the second opening panel 820 is output to the panel driver 700.

  The panel driving unit 900 moves the second opening panel 820 in a substantially parallel direction with respect to the first opening panel 810 surface and the second opening panel 820 surface based on a command signal from the intake opening ratio control unit 700. Thus, the relative positions of the first opening panel 810 and the second opening panel 820 are changed.

  That is, when the difference measurement value between the exhaust temperature and the intake air temperature is larger than the threshold value, the panel drive unit 900 determines that the opening rate of the intake port 300 is increased based on the command signal of the intake opening rate control unit 700. The two opening panels 820 are moved. More specifically, as shown in FIG. 2A, the panel drive unit 900 opens the second opening panel 820 so that the first through hole 811 and the second through hole 821 are completely opposed to each other. Move. As a result, the opening ratio of the intake port 300 is set as large as 80%.

  On the other hand, when the difference measurement value between the exhaust temperature and the intake air temperature is smaller than the threshold value, the panel drive unit 900 determines that the opening ratio of the intake port 300 is small based on the command signal of the intake opening ratio control unit 700. The two opening panels 820 are moved. More specifically, as shown in FIG. 2B, the panel driving unit 900 includes the second opening panel 820 so that the first through hole 811 and the second through hole 821 do not completely face each other. Move. Thereby, the opening ratio of the inlet 300 is set to be as small as 60%.

  In this way, the intake opening ratio control unit 700 adjusts the relative positions of the first opening panel 811 and the second opening panel 821 based on the difference value between the exhaust temperature and the intake air temperature, thereby The aperture ratio of the mouth 300 is controlled.

  The configuration of the electronic device accommodation rack 1000 has been described above.

  Next, the operation of the electronic device accommodation rack 1000 will be described.

  FIG. 4 is a diagram illustrating an operation flow of the electronic device housing rack 1000. FIG. 5 is a diagram illustrating a control example of the electronic device housing rack 1000.

  As shown in FIG. 4, first, the intake side temperature sensor 500 measures the intake temperature on the front side of the rack body 200 (S401). Note that the intake air temperature is the temperature of the air drawn from the intake port 300 as described above. The intake-side temperature sensor 500 passes the intake air temperature measurement data to the intake opening ratio control unit 700.

  Next, the exhaust side temperature sensor 600 measures the exhaust temperature on the back side of the rack body 200 (S402). The exhaust temperature is the temperature of the air discharged to the exhaust port 400. The exhaust-side temperature sensor 600 passes the exhaust temperature measurement data to the intake opening ratio control unit 700.

  Next, the intake opening ratio control unit 700 compares the temperature difference (difference measured value of the exhaust gas temperature and the intake air temperature) with the set temperature (S404). More specifically, first, the intake opening ratio control unit 700 calculates a temperature difference (difference measurement value of the exhaust gas temperature and the intake air temperature), and then compares the temperature difference with a set temperature (threshold value).

  In the example shown in FIG. 5, the temperature difference of the third storage chamber 100 from the top is equal to or lower than the set temperature (temperature difference ≦ set temperature), while the temperature difference of the other storage chambers 100 is It is assumed that the temperature is higher than the set temperature (temperature difference> set temperature).

  When the temperature difference is larger than the set temperature (temperature difference> set temperature), the intake opening rate control unit 700 performs control to improve the opening rate of the intake port 300 (S405, Yes). Specifically, when the difference measurement value between the exhaust temperature and the intake air temperature is larger than the threshold value, the intake opening ratio control unit 700 moves the second opening panel 820 so that the opening ratio of the intake port 300 increases. A command signal is output to the panel driving unit 700. In other words, as shown in FIG. 2A, the intake opening ratio control unit 700 has the second opening so that the first through hole 811 and the second through hole 821 are disposed so as to face each other completely. A command signal for moving the panel 820 is output to the panel drive unit 700.

  When the difference measurement value between the exhaust temperature and the intake air temperature is larger than the threshold value, the panel drive unit 900 determines that the opening rate of the intake port 300 is increased based on the command signal of the intake opening rate control unit 700. The two opening panels 820 are moved. That is, the panel driving unit 900 moves the second opening panel 820 so that the first through hole 811 and the second through hole 821 completely face each other, as shown in FIG. As a result, the opening ratio of the intake port 300 is set as large as 80%. As a result, the amount of outside air supplied to the electronic device 10 is increased. In general, the electronic device 10 having a relatively high load has a large temperature rise from the intake air temperature to the exhaust gas temperature because the internal temperature of the apparatus is high. Therefore, when the temperature rise from the intake air temperature to the exhaust gas temperature is large, it is presumed that the electronic device 10 having a relatively high load when operating is housed in the housing chamber 100. Therefore, this control is suitable for cooling the electronic device 10 having a relatively large load when operating.

  On the other hand, when the temperature difference is equal to or lower than the set temperature (temperature difference ≦ set temperature), the intake opening ratio control unit 700 performs control to suppress the opening ratio of the intake port 300 (No in S406). Specifically, when the measured difference value between the exhaust temperature and the intake air temperature is equal to or less than the threshold value, intake air opening ratio control unit 700 moves second opening panel 820 so that the opening ratio of air inlet 300 is reduced. A command signal is output to the panel driving unit 700. That is, as shown in FIG. 2B, the intake opening ratio control unit 700 is arranged such that the first through hole 811 and the second through hole 821 are arranged so as not to face each other completely. A command signal for moving the opening panel 820 is output to the panel driving unit 700.

  When the difference measurement value between the exhaust temperature and the intake air temperature is smaller than the threshold value, the panel drive unit 900 determines that the opening ratio of the intake port 300 is small based on the command signal of the intake opening ratio control unit 700. The two opening panels 820 are moved. More specifically, as shown in FIG. 2B, the panel driving unit 900 includes the second opening panel 820 so that the first through hole 811 and the second through hole 821 do not completely face each other. Move. Thereby, the opening ratio of the inlet 300 is set to be as small as 60%. In general, in the electronic device 10 having a relatively low load, the temperature rise from the intake air temperature to the exhaust gas temperature is small because the internal temperature of the apparatus is low. Therefore, when the temperature rise from the intake air temperature to the exhaust gas temperature is small, it is presumed that the electronic device 10 having a relatively low load when operating is housed in the housing chamber 100. Therefore, this control is suitable for cooling the electronic device 10 having a relatively small load when operating.

  In addition, each process of S401-S406 is performed continuously.

  The operation of the electronic device accommodation rack 1000 has been described above.

  As described above, the electronic device housing rack 1000 according to the first embodiment of the present invention includes the plurality of housing chambers 100, the rack body 200, the air inlet 300, the air outlet 400, the air intake side temperature sensor 500, An exhaust-side temperature sensor 600, an intake opening ratio control unit 700, and a filter 800 are provided. The accommodation room 100 accommodates the electronic device 10. The rack body 200 has a plurality of storage chambers 100. The intake port 300 is provided on the front side of each of the accommodation chambers 100. The air inlet 300 sucks air outside the rack body 200. The exhaust port 400 is provided on the back side of each of the storage chambers 100. The exhaust port 400 discharges the air sucked from the intake port 300 to the outside of the storage chamber 100 on the back side of each of the storage chambers 100. The intake side temperature sensor 500 is provided on the front side of each of the accommodation chambers 100. The intake-side temperature sensor 500 measures the intake air temperature, which is the temperature of air drawn from the intake port 300. The exhaust side temperature sensor 600 is provided on the back side of each of the accommodation chambers 100. The exhaust side temperature sensor 600 measures the exhaust temperature, which is the temperature of the air discharged to the exhaust port 400. The intake opening ratio control unit 700 controls the opening ratio of the intake port 300 for each storage chamber 100. The filter 800 is set to have a predetermined aperture ratio. The intake opening ratio control unit 700 controls the opening ratio of the intake port 300 by disposing the filter 800 at the intake port 300 based on the difference value between the exhaust gas temperature and the intake air temperature.

  Thus, the intake side temperature sensor 500 measures the intake air temperature on the front side of each of the accommodation chambers 100. The exhaust side temperature sensor 600 measures the exhaust temperature on the back side of each of the accommodation chambers 100. And the intake opening ratio control part 700 arrange | positions the filter 800 set to the predetermined | prescribed opening ratio in the inlet 300 based on the difference value of exhaust temperature and intake temperature for every some storage chamber 100, The opening ratio of the inlet 300 is controlled. Thereby, in the electronic device accommodation rack 1000, the air sucked from the intake port 300 can be adjusted according to the difference value between the exhaust temperature and the intake air temperature.

  For example, when the difference value between the exhaust temperature and the intake air temperature of a certain storage chamber 100 is relatively large, the electronic device 10 in the storage chamber 100 has a relatively high load when operated. In this case, the intake opening ratio control unit 700 arranges the filter 800 set at a predetermined opening ratio at the intake opening 300 so that the opening ratio of the intake opening 300 is increased. Thereby, the cooling air having a relatively large air volume can be supplied to the electronic device 10. On the other hand, when the difference value between the exhaust temperature and the intake air temperature of a certain storage chamber 100 is relatively small, the electronic device 10 in the storage chamber 100 has a relatively low load when operated. In this case, the intake opening ratio control unit 700 arranges the filter 800 set to a predetermined opening ratio at the intake port 300 so that the opening ratio of the intake port 300 is reduced. Thereby, the cooling air having a relatively small air volume can be supplied to the electronic device 10. In this way, the opening rate of the air inlet 300 is controlled according to the load state of the plurality of electronic devices 10, and the amount of cooling air supplied to the electronic device 10 is set for each electronic device 10 (accommodating chamber 100). Can be adjusted. That is, the cooling air having an appropriate air volume is distributed and provided to both the electronic device 10 having a relatively high load when operating and the electronic device 10 having a relatively low load when operating. Can do. Therefore, the cooling capacity of the cooling facility of the server room in which the electronic device accommodation rack 1000 is installed can be used appropriately and effectively.

  As explained in the background art, in general, server room cooling equipment is set to a constant environmental temperature in accordance with more demanding electronic equipment, that is, electronic equipment with a lower maximum temperature in the guaranteed operating temperature range. Yes. For this reason, there is a problem that an electronic device having a high upper limit temperature in the guaranteed operating temperature range is excessively cooled, and cooling by the cooling facility does not function effectively.

  On the other hand, in the electronic device housing rack 1000 of the present invention, as described above, both the electronic device 10 having a relatively high load when operating and the electronic device 10 having a relatively low load when operating. On the other hand, it is possible to distribute and provide cooling air having an appropriate air volume. For this reason, it is possible to control to distribute the cooling air for providing the electronic device 10 having a relatively low load when operating to the electronic device 10 having a relatively high load when operating. Thereby, since the setting temperature of the cooling equipment of a server room can be set high, the power consumption of a cooling equipment can be suppressed.

  Moreover, in the electronic device housing rack 1000 of the present invention, unlike the technique described in Patent Document 1, it is not necessary to arrange a plurality of louvers having a complicated configuration. Therefore, the electronic device 10 can be appropriately cooled with a simpler configuration as compared with the technique described in Patent Document 1.

  As described above, according to the electronic device housing rack 1000 according to the present invention, the power consumption of the cooling facility in the room where the electronic device 10 is installed is suppressed, and the electronic device 10 is appropriately configured with a simple configuration. Can be cooled.

  Further, the electronic device housing rack 1000 according to the first embodiment of the present invention includes a first opening panel 810 and a second opening panel 820. In the first opening panel 810, a plurality of first through holes 811 are arranged at predetermined intervals. A plurality of second through holes 921 are arranged in the second opening panel 820 at a predetermined interval. The second opening panel 820 is overlaid on the first opening panel 810. The intake opening ratio control unit 700 adjusts the relative positions of the first opening panel 810 and the second opening panel 820 based on the difference value between the exhaust temperature and the intake temperature, thereby opening the opening ratio of the intake port 300. To control. As described above, the aperture ratios of the plurality of intake ports 300 can be set by overlapping the two aperture panels and moving their relative positions according to the control of the intake aperture ratio control unit 700. .

  In the electronic device housing rack 1000 according to the first embodiment of the present invention, the intervals between the plurality of first through holes 811 and the intervals between the plurality of second through holes 821 are the same. Thereby, when the first opening panel 810 and the second opening panel 820 are overlapped so that the first through hole 811 and the second through hole 821 face each other, the opening ratio of the air intake 300 is set to the first opening ratio. This corresponds to the aperture ratio of both the aperture panel 810 and the second aperture panel 820. Therefore, the opening ratio of the intake port 300 can be set more easily.

  In addition, the electronic device storage rack 1000 according to the first embodiment of the present invention includes a panel drive unit 900. The panel driving unit 900 moves the first opening panel 810 or the second opening panel 820 in a substantially parallel direction with respect to the first opening panel 810 surface and the second opening panel 820 surface, thereby The relative positions of the aperture panel 810 and the second aperture panel 820 are changed. The intake opening ratio control unit 700 causes the panel drive unit 900 to change the relative position of the first opening panel 810 or the second opening panel 820 based on the difference value between the exhaust temperature and the intake air temperature, thereby The aperture ratio of the mouth 300 is controlled. As a result, the relative position of the first opening panel 810 or the second opening panel 820 can be reliably changed by the power of the panel drive unit 900, and the opening ratio of the predetermined inlet 300 can be more reliably set. Can be set to

  In the electronic device storage rack 1000 according to the first embodiment of the present invention, the plurality of storage chambers 100 are arranged in the rack body 200 so as to be stacked. Thereby, the installation space of the electronic device accommodation rack 1000 can be made small.

<Second Embodiment>
The configuration of the electronic device housing rack 1000A according to the second embodiment of the present invention will be described with reference to the drawings.

  FIG. 6 is a diagram illustrating a configuration of the electronic device housing rack 1000A. FIG. 6A is a side perspective view of the electronic device housing rack 1000A. FIG. 6B is a front perspective view of the electronic device accommodation rack 1000A, and is a view showing an arrow B in FIG.

  In FIG. 6, constituent elements equivalent to those shown in FIGS. 1 to 4 are denoted by the same reference numerals as those shown in FIGS. 1 to 4.

  As shown in FIGS. 6A and 6B, the electronic device housing rack 1000A includes a housing chamber 100, a rack body 200, an intake port 300, an exhaust port 400, an intake-side temperature sensor 500, and the like. The exhaust-side temperature sensor 600, the intake opening ratio control unit 700A, and the filter 800A are provided.

  Here, the electronic device housing rack 1000 shown in FIGS. 1 (a) and 1 (b) is compared with the electronic device housing rack 1000A shown in FIGS. 6 (a) and 6 (b).

  As shown in FIG. 1A and FIG. 1B, the electronic device housing rack 1000 includes an intake opening ratio control unit 700 and a filter 800. On the other hand, as shown in FIG. 6A and FIG. 6B, the electronic device housing rack 1000A includes an intake opening ratio control unit 700A and a filter 800A. That is, the intake opening ratio control unit and the filter are different from each other.

  As shown in FIGS. 6A and 6B, the intake opening ratio control unit 700 </ b> A is provided on the front side of each storage chamber 100 of the rack body 200. However, the intake opening ratio control unit 700 </ b> A may be provided at a location other than the front side of each accommodation chamber 100 as long as it is provided for each accommodation chamber 100. Each intake opening ratio control unit 700 </ b> A controls the opening ratio of the intake port 300 for each of the plurality of storage chambers 100. At this time, the intake opening ratio control unit 700A sets the filter 800A to the intake port 300 based on the difference value between the exhaust temperature measured by the exhaust side temperature sensor 600 and the intake air temperature measured by the intake side temperature sensor 500. By installing, the opening ratio of the inlet 300 is controlled. The control method of the intake opening ratio control unit 700A will be described in detail later with reference to FIG.

  As shown in FIGS. 6A and 6B, the filter 800 </ b> A is provided on the front side of each storage chamber 100 of the rack body 200. Filter 800A is preset to a predetermined aperture ratio. In the first embodiment, it has been described that the filter 800 includes the first opening panel 810 and the second opening panel 820. On the other hand, the filter 800A in the present embodiment is configured by a single flexible sheet.

  Next, the configuration of the control system of the electronic equipment housing rack 1000A will be described. FIG. 7 is a block diagram illustrating a configuration of a control system of the electronic device housing rack 1000A.

  In FIG. 7, constituent elements that are equivalent to the constituent elements shown in FIGS. 1 to 6 are assigned the same reference numerals as those shown in FIGS. 1 to 6.

  As shown in FIG. 7, the control system of the electronic equipment housing rack 1000A includes an intake side sensor 500, an exhaust side sensor 600, an intake opening ratio control unit 700A, a filter 800A, and a filter drive unit 900A. Composed.

  As shown in FIG. 7, the intake side sensor 500 and the exhaust side sensor 600 are connected to the intake opening ratio control unit 700A. Further, an intake opening ratio control unit 700A and a filter driving unit 900A are connected.

  The filter driving unit 900A moves the filter 800A so that the area covered with the inlet 300 by the filter 800A can be changed. As shown in FIG. 6B, the entire surface of the intake port 300 at the fourth stage from the top is covered with a filter 800A. On the other hand, only a part of the intake port 300 is covered except for the intake port 300 other than the fourth stage from the top. The intake opening ratio control unit 700A adjusts the opening ratio of the intake port 300 according to the area covered by the filter 800A.

  More specifically, the functions of the intake opening ratio control unit 700A and the filter driving unit 900A will be described.

  That is, the intake opening ratio control unit 700A calculates a difference value between the exhaust temperature measured by the exhaust side temperature sensor 600 and the intake air temperature measured by the intake side temperature sensor 500. Thereby, the temperature that rises due to heat dissipation of the electronic device 10 is calculated.

  Then, based on the measured value of the difference between the exhaust gas temperature and the intake air temperature, intake opening ratio control unit 700A outputs a command signal for changing the area covered with intake port 300 by filter 800A to filter drive unit 900A. To do. At this time, a predetermined threshold value is set for the difference value between the exhaust gas temperature and the intake air temperature, as in the first embodiment.

  When the difference measurement value between the exhaust temperature and the intake air temperature is larger than the threshold value, the intake opening ratio control unit 700A commands to reduce the area covered with the intake port 300 by the filter 800A so that the opening ratio of the intake port 300 is increased. The signal is output to the filter driver 900A.

  On the other hand, when the difference measurement value between the exhaust temperature and the intake air temperature is smaller than the threshold value, the intake opening ratio control unit 700A increases the area where the inlet port 300 is covered by the filter 800A so that the opening ratio of the intake port 300 becomes smaller. The command signal to be output is output to the filter driver 900A.

  Filter drive unit 900A moves filter 800A based on a command signal from intake opening ratio control unit 700A.

  That is, when the difference measurement value between the exhaust temperature and the intake air temperature is larger than the threshold value, the filter driving unit 900A has a larger area in which the intake port 300 is covered by the filter 800A based on the command signal from the intake opening ratio control unit 700A. Thus, the filter 800A is moved. Thereby, the opening ratio of the inlet 300 is set relatively large.

  On the other hand, when the difference measurement value between the exhaust temperature and the intake air temperature is smaller than the threshold value, the filter drive unit 900A reduces the area where the intake port 300 is covered by the filter 800A based on the command signal of the intake opening ratio control unit 700A. Thus, the filter 800A is moved. Thereby, the opening ratio of the inlet 300 is set to be relatively small.

  In this way, intake opening ratio control unit 700A controls the opening ratio of intake port 300 by moving filter 800A based on the difference value between the exhaust gas temperature and the intake air temperature.

  The configuration of the electronic device accommodation rack 1000A has been described above.

  Next, the operation of the electronic device housing rack 1000A will be described.

  Since the operation flow of the electronic device housing rack 1000A conforms to the content shown in FIG. 4, the operation of the electronic device housing rack 1000A will be described with reference to FIG.

  As shown in FIG. 4, first, the intake side temperature sensor 500 measures the intake temperature on the front side of the rack body 200 (S401). Then, intake-side temperature sensor 500 delivers intake air temperature measurement data to intake opening ratio control unit 700A.

  Next, the exhaust side temperature sensor 600 measures the exhaust temperature on the back side of the rack body 200 (S402). Then, the exhaust-side temperature sensor 600 delivers the exhaust temperature measurement data to the intake opening ratio control unit 700A.

  Next, the intake opening ratio control unit 700A compares the temperature difference (difference measured value of the exhaust gas temperature and the intake air temperature) with the set temperature (S404). More specifically, first, the intake opening ratio control unit 700A calculates a temperature difference (difference measurement value of the exhaust gas temperature and the intake air temperature), and then compares the temperature difference with the set temperature (threshold value).

  When the temperature difference is larger than the set temperature (temperature difference> set temperature), the intake opening ratio control unit 700A performs control to improve the opening ratio of the intake port 300 (S405, Yes). Specifically, when the difference measurement value between the exhaust temperature and the intake air temperature is larger than the threshold value, the intake opening ratio control unit 700A filters the command signal for moving the filter 800A so that the opening ratio of the intake port 300 increases. Output to the drive unit 900A. That is, the intake opening ratio control unit 700A outputs a command signal for moving the filter 800A to the filter driving unit 900A so that the area covered with the intake port 300 is increased.

  When the difference measurement value between the exhaust temperature and the intake air temperature is larger than the threshold value, the filter driving unit 900A filters the intake port 300 so that the opening rate of the intake port 300 is increased based on the command signal of the intake opening rate control unit 700A. Move 800A. Thereby, the opening ratio of the inlet 300 is set relatively large. As a result, the amount of outside air supplied to the electronic device 10 is increased. In general, the electronic device 10 having a relatively high load has a large temperature rise from the intake air temperature to the exhaust gas temperature because the internal temperature of the apparatus is high. Therefore, when the temperature rise from the intake air temperature to the exhaust gas temperature is large, it is presumed that the electronic device 10 having a relatively high load when operating is housed in the housing chamber 100. Therefore, this control is suitable for cooling the electronic device 10 having a relatively large load when operating.

  On the other hand, when the temperature difference is equal to or lower than the set temperature (temperature difference ≦ set temperature), the intake opening ratio control unit 700A performs control to suppress the opening ratio of the intake port 300 (No in S406). Specifically, when the difference measurement value between the exhaust temperature and the intake air temperature is equal to or smaller than the threshold value, the intake opening ratio control unit 700A filters the command signal for moving the filter 800A so that the opening ratio of the intake port 300 becomes small. Output to the drive unit 900A. That is, the intake opening ratio control unit 700A outputs a command signal for moving the filter 800A to the filter driving unit 900A so that the area covered with the intake port 300 is reduced.

  Then, when the difference measurement value between the exhaust temperature and the intake air temperature is smaller than the threshold value, the filter driving unit 900A filters the intake port 300 so that the opening ratio of the intake port 300 becomes small based on the command signal of the intake opening ratio control unit 700A. Move 800A. Thereby, the opening ratio of the inlet 300 is set to be relatively small. In general, in the electronic device 10 having a relatively low load, the temperature rise from the intake air temperature to the exhaust gas temperature is small because the internal temperature of the apparatus is low. Therefore, when the temperature rise from the intake air temperature to the exhaust gas temperature is small, it is presumed that the electronic device 10 having a relatively low load when operating is housed in the housing chamber 100. Therefore, this control is suitable for cooling the electronic device 10 having a relatively small load when operating.

  In addition, each process of S401-S406 is performed continuously.

  The operation of the electronic device accommodation rack 1000 has been described above.

  As described above, the electronic device housing rack 1000A according to the second embodiment of the present invention includes the filter driving unit 900A. The filter driving unit 900A moves the filter 800A so that the area covered with the inlet 300 by the filter 800A can be changed. The intake opening ratio control unit 900A controls the opening ratio of the intake port 300 by causing the filter driving unit 900A to change the area where the intake port 300 is covered by the filter 800A based on the difference value between the exhaust temperature and the intake air temperature. To do. Accordingly, the filter 800A can be reliably moved by the power of the filter drive unit 900A, and can be set so that the opening ratio of the predetermined intake port 300 is more reliably obtained.

  In the above-described embodiment, the interior of the rack body 200 is divided into partitions and the storage chamber 100 is provided. And the opening ratio of the inlet 300 was controlled for every storage chamber 100. On the other hand, a method in which the inside of the rack body 200 is not divided into partitions can be considered. In this case, the plurality of storage chambers 100 are not provided. For example, in the rack body 200, only one intake temperature sensor 300, one exhaust temperature sensor 400, and one intake opening ratio control unit 900 are provided. The air inlet 300 is formed so as to open substantially the entire front side of the rack body 200. The intake opening ratio control unit 900 controls the opening ratio of the intake port 300 corresponding to the entire front surface of the rack body 200. Thereby, detailed temperature control cannot be performed for each electronic device 10. However, with respect to the rack body 200 that has a relatively low load when all of the electronic devices 10 in the rack body 200 are operated, the rack body 200 as a whole suppresses the opening ratio of the air inlet 300, thereby reducing the rack body 200. It is possible to effectively use the cooling facility of the server room where the computer is installed.

  Further, a temperature sensor is provided on the front side or the back side of the rack body 200, and the opening ratio of the intake port 300 is not controlled using the measured value of the temperature sensor. It is also possible to provide a system in which 10 can communicate wirelessly remotely. In this case, the intake opening ratio control unit 900 directly reads the load of the electronic device 10. According to this, it is possible to have functions and effects equivalent to those of the present invention without using a temperature sensor.

  The present invention is not limited to a rack body on which an electronic device is mounted, but by controlling the inflow of air in a device or a housing that sucks air from the front surface of the rack body and discharges air from the back surface of the rack body. The present invention can also be applied to a device having a mechanism capable of realizing optimum temperature control.

  In addition, the present invention can be used not only to cool an electronic device but also to warm an electronic device. Also in this case, optimal temperature control can be realized. Thereby, this invention can be widely applied with respect to an environment with high predominance.

  The present invention has been described above based on the embodiment. The embodiment is an exemplification, and various modifications, increases / decreases, and combinations may be added to the above-described embodiments without departing from the gist of the present invention. It will be understood by those skilled in the art that modifications to which these changes, increases / decreases, and combinations are also within the scope of the present invention.
