Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings. However, although the embodiments described below have technically preferable limitations for carrying out the present invention, the scope of the invention is not limited to the following. In all the drawings used in the following embodiments, the same reference numerals are given to the same parts unless there is a specific reason. Further, in the following embodiments, repeated explanations may be omitted for similar configurations and operations.

(First Embodiment)
First, the angle adjustment system according to the first embodiment of the present invention will be described with reference to the drawings. The angle adjustment system of the present embodiment is a system that adjusts the mounting angle of an information processing device mounted on a rack installed in a room such as a server room of a data center. The mounting angle is an angle formed by the lower surface of the information processing device and the horizontal plane when the information processing device is tilted. In the following, an example of adjusting the mounting angle of the servers mounted on the racks arranged inside the server room for each server will be described.

FIG. 1 is a block diagram showing an example of the configuration of the angle adjustment system 1 of the present embodiment. As shown in FIG. 1, the angle adjusting system 1 includes a mounting housing 11, a sensor 12, an angle changing mechanism 13, a blower mechanism 14, and a control device 15. The mounting housing 11, the sensor 12, the angle changing mechanism 13, and the blower mechanism 14 constitute the angle adjusting device 10.

FIG. 2 is a perspective view of the angle adjusting device 10. As shown in FIG. 2, the mounting housing 11 and the ventilation mechanism 14 are mounted on the upper surface of the angle changing mechanism 13. In the following, the side surface portion and the bottom surface portion of the ventilation mechanism 14 are also regarded as a part of the mounting housing 11.

The mounting housing 11 is a housing for mounting the server inside. The mounting housing 11 has an intake surface 111 for taking in cold air and an exhaust surface 112 for discharging warm air warmed by the heat generated by the operation of the server. A blower mechanism 14 is installed on the side of the intake surface 111. A sensor 12 is installed on the side of the exhaust surface 112. The cold air sent by the blower mechanism 14 is taken into the inside of the mounting housing 11 from the intake surface 111. The warm air warmed by the heat generated by the operation of the server mounted inside the mounting housing 11 is discharged from the exhaust surface 112.

The sensor 12 is installed on the exhaust surface 112 of the mounting housing 11. The sensor 12 measures the air volume per unit time of the exhaust gas discharged from the exhaust surface 112. The sensor 12 transmits the measured air volume data per unit time to the control device 15. Further, the sensor 12 measures the temperature of the exhaust gas discharged from the exhaust surface 112. The sensor 12 transmits the temperature data regarding the measured temperature to the control device 15. The sensor for measuring the air volume per unit time (air volume sensor) and the sensor for measuring the exhaust temperature (temperature sensor) may be separately configured. Further, the sensor 12 may be configured to measure not only temperature and air volume but also atmospheric pressure and humidity.

The angle changing mechanism 13 is a mechanism for adjusting the mounting angle of the server. The angle changing mechanism 13 adjusts the mounting angle of the mounting housing 11 so that the intake surface 111 of the mounting housing 11 faces downward and the exhaust surface 112 of the mounting housing 11 faces upward.

FIG. 3 is a conceptual diagram showing an example of adjusting the mounting angle of the mounting housing 11 of the angle adjusting system 1. As shown in FIG. 3, the angle changing mechanism 13 has a pedestal 130, a jack portion 131, a support portion 132, and a sliding portion 133.

The pedestal 130 is a pedestal on which the mounting housing 11 is placed. The pedestal 130 is formed with a storage tank 134 for accommodating the jack portion 131 and the support portion 132.

The jack portion 131 is a mechanism for lifting the mounting housing 11 to change the mounting angle. In the example of FIG. 3, the jack portion 131 is a rod-shaped member having a first end rotatably connected to the inside of the storage tank 134 of the pedestal 130 and a second end rotatably connected to the support portion 132. be. When the jack portion 131 is driven according to the control of the control device 15, the side of the second end connected to the support portion 132 is lifted with the first end as a fulcrum. The shape and operating principle of the jack portion 131 are not limited as long as it operates so as to lift the mounting housing 11. For example, the jack portion 131 can be realized by an electro-hydraulic jack driven by hydraulic control.

The support portion 132 is installed on the lower surface of the mounting housing 11 and rotatably supports the second end of the jack portion 131. When the second end of the jack portion 131 is lifted, the connection portion between the second end of the jack portion 131 and the support portion 132 is rotated, and the exhaust surface 112 side of the mounting housing 11 is lifted.

The sliding portion 133 is installed on the pedestal 130 so that the upper surface side protrudes. When the jack portion 131 is driven, the exhaust surface 112 side of the mounting housing 11 is lifted, and the lower end of the mounting housing 11 on the intake surface 111 side slides on the upper surface of the sliding portion 133. On the upper surface of the sliding portion 133, the lower end of the mounting housing 11 on the intake surface 111 side slides as the jack portion 131 is driven, and the mounting angle of the mounting housing 11 can be maintained when the jack portion 131 stops. It is preferable to have a friction coefficient of. For example, the sliding portion 133 may be formed of members in a rail shape.

4 and 5 are conceptual diagrams for explaining an example of adjusting the mounting angle of the mounting housing 11 by operating the angle changing mechanism 13. 4 and 5 show a part of the pedestal 130 seen through for ease of explanation.

FIG. 4 is a conceptual diagram for explaining a state of the angle changing mechanism 13 when the mounting angle of the mounting housing 11 is 0 degrees (also referred to as an initial position). When the mounting angle is 0 degrees, the jack portion 131 and the support portion 132 are housed inside the storage tank 134.

FIG. 5 is a conceptual diagram for explaining the state of the angle changing mechanism 13 when the mounting angle of the mounting housing 11 is θ degree (0 <θ <90). When the mounting angle is set to θ degree, the side of the support portion 132 of the jack portion 131 is lifted according to the control of the control device 15, and the lower end of the mounting housing 11 on the intake surface 111 side slides on the upper surface of the sliding portion 133. .. Then, the mounting housing 11 is held in a state in which the side of the exhaust surface 112 is tilted upward at a set mounting angle (θ degree).

As shown in FIG. 5, when the ventilation mechanism 14 operates with the mounting angle adjusted so that the side of the intake surface 111 faces downward and the side of the exhaust surface 112 faces upward, cold air is taken in from the intake surface 111. The cold air taken in from the intake surface 111 is warmed by the heat generated by the operation of the server. The warmed air is discharged from the exhaust surface 112.

The ventilation mechanism 14 takes in cold air inside the mounting housing 11, and discharges warm air warmed by the heat generated by the operation of the server mounted inside the mounting housing 11 to the outside of the mounting housing 11. It has at least one fan 140 for this purpose (Fig. 2). FIG. 2 shows an example in which the blower mechanism 14 has four fans 140, but the number and specifications of the fan 140s of the blower mechanism 14 can be arbitrarily set. In the present embodiment, an example in which the blower mechanism 14 is arranged on the intake surface 111 side of the mounting housing 11 is shown, but the blower mechanism 14 may be arranged on the exhaust surface 112 side of the mounting housing 11.

The ventilation mechanism 14 may use a server platform management mechanism such as BMC (Baseboard Management Controller) instead of the external system. By using the platform management mechanism, the air volume can be measured by controlling the rotation speed of the fan inside the server.

The control device 15 receives air volume data and temperature data from the sensor 12. The control device 15 controls the angle changing mechanism 13 to adjust the mounting angle of the mounting housing 11. Further, the control device 15 controls the rotational state of the fan 140 included in the blower mechanism 14, and controls the amount of cold air taken into the mounting housing 11. For example, the control device 15 is realized as a microprocessor installed inside the pedestal 130. Further, for example, the control device 15 may be realized as software installed on a server mounted on the mounting housing 11. Further, for example, the control device 15 may be configured as a management device (not shown) that centrally manages a rack on which a plurality of servers are mounted.

The control device 15 executes an angle adjusting process for adjusting the mounting angle of the mounting housing 11. The control device 15 performs an angle adjustment process at a stage before the server mounted on the mounting housing 11 operates or while the server mounted on the mounting housing 11 is operating. In the angle adjustment process, the control device 15 controls the angle changing mechanism 13 so that the mounting angle of the mounting housing 11 on which the server is mounted becomes a preset angle. The control device 15 receives the air volume data from the sensor 12 in a state where the mounting angle of the mounting housing 11 is set. The control device 15 records the value (air volume) of the received air volume data in association with the mounting angle of the mounting housing 11. When the control device 15 records the air volume at a certain mounting angle, the control device 15 controls the angle changing mechanism 13 to change the mounting angle of the mounting housing 11. The control device 15 receives the air volume data from the sensor 12 at the changed mounting angle, and records the value (air volume) of the received air volume data in association with the mounting angle. That is, the control device 15 sets the mounting angles of the mounting housing 11 at a plurality of preset angles, and at each angle, the value (air volume) of the received air volume data is set to the mounting angle of the mounting housing 11. Record in association with. Then, the control device 15 controls the angle changing mechanism 13 so as to adjust the mounting housing 11 to the mounting angle at which the air volume is maximum.

Further, the control device 15 receives temperature data from the sensor 12 at a predetermined timing while the server mounted inside the mounting housing 11 in which the mounting angle is set is in operation. For example, the control device 15 acquires temperature data from the sensor 12 at a predetermined time interval such as a 5-minute interval or a preset predetermined time.

When the control device 15 receives the temperature data, if the temperature data measured at a time preceding a predetermined time (hereinafter, also referred to as a reference time) is recorded, the exhaust temperature measured at the reference time is recorded. Ty is compared with the exhaust temperature Tx measured at a predetermined timing. The control device 15 executes the above-mentioned angle adjustment process when the absolute value of the difference between the exhaust temperature Ty measured at the reference time and the exhaust temperature Tx measured at the predetermined timing is equal to or greater than the predetermined temperature difference. do.

The above is a description of an example of the configuration of the angle adjustment system 1. The configuration of FIGS. 1 to 5 is an example, and the configuration of the angle adjusting system 1 of the present embodiment is not limited to the same configuration.

〔Control device〕
Next, the configuration of the control device 15 will be described with reference to the drawings. FIG. 6 is a block diagram showing an example of the configuration of the control device 15. As shown in FIG. 6, the control device 15 includes an air volume data acquisition unit 151, a setting candidate data storage unit 152, a drive condition setting unit 153, an angle control unit 154, a temperature data acquisition unit 155, a temperature history data storage unit 156, and temperature monitoring. It has a unit 157 and a ventilation control unit 158.

The air volume data acquisition unit 151 acquires air volume data from the sensor 12. The air volume data acquisition unit 151 stores the setting candidate data in which the acquired air volume data and the mounting angle at that time are associated with each other in the setting candidate data storage unit 152.

The setting candidate data storage unit 152 stores the setting candidate data in which the mounting angle of the mounting housing 11 and the air volume data measured at the mounting angle are associated with each other.

FIG. 7 is an example of a table (setting candidate table 162) that summarizes the setting candidate data stored in the setting candidate data storage unit 152. In the setting candidate table 162, the mounting angle is changed from 0 degrees to every 5 degrees, and the setting candidate data in which the air volume (arbitrary unit) measured at each mounting angle and the mounting angle are associated with each other is collected. In the example of FIG. 7, it is assumed that the air volume is maximum (25) when the mounting angle is 50 degrees.

The drive condition setting unit 153 outputs the mounting angle set in the mounting housing 11 to the angle control unit 154 during the execution of the angle adjustment process. When the angle adjustment process is completed, the drive condition setting unit 153 refers to the setting candidate data stored in the setting candidate data storage unit 152 and acquires the mounting angle that maximizes the air volume. The drive condition setting unit 153 outputs the mounting angle at which the air volume is maximized to the angle control unit 154. In the case of the setting candidate table 162 of FIG. 7, the drive condition setting unit 153 outputs the mounting angle (50 degrees) at which the air volume is maximum (25) to the angle control unit 154.

The angle control unit 154 acquires the mounting angle from the drive condition setting unit 153. The angle control unit 154 controls the angle changing mechanism 13 so as to obtain the acquired mounting angle. In the case of the example of FIG. 7, the angle control unit 154 receives the mounting angle (50 degrees) from the drive condition setting unit 153 and adjusts the mounting angle of the mounting housing 11 to that angle (50 degrees).

The temperature data acquisition unit 155 acquires temperature data from the sensor 12. The temperature data acquisition unit 155 stores the acquired temperature data in the temperature history data storage unit 156 in association with the measurement time of the temperature data. In the present embodiment, the temperature data acquisition unit 155 acquires temperature data while the server mounted on the mounting housing 11 is operating.

The temperature history data storage unit 156 stores the temperature history data in which the measurement time of the temperature data and the temperature measured at the measurement time are associated with each other.

FIG. 8 is an example of a table (temperature history table 166) that summarizes the temperature history data stored in the temperature history data storage unit 156. In the temperature history table 166, the temperature history data in which the measurement time of the temperature data and the exhaust temperature measured at the measurement time are associated with each other is collected. FIG. 8 shows an example of recording the temperature measured at the measurement time every 5 minutes from 12:00.

_{When the temperature data (exhaust temperature T x} ) is acquired by the temperature data acquisition unit 155, the temperature monitoring unit 157 refers to the temperature history data storage unit 156. The temperature monitoring unit 157 refers to the temperature history data storage unit 156, and determines whether or not there is _{temperature data (exhaust temperature Ty} ) measured at a time (reference time) that is a predetermined time before the measurement time of the temperature data. Check. _{When the temperature data (exhaust temperature T x} ) measured at the reference time is stored in the temperature history data storage unit 156, the temperature monitoring unit 157 measures the most recently measured exhaust temperature T x and the reference time. Compare with the exhaust temperature T _y. And exhaust temperature Tx which is measured most recently, when the temperature difference between the exhaust temperature T _y, which is measured in the reference time is equal to or higher than the predetermined temperature difference, the angle adjustment processing is executed again to the drive condition setting section 153.

For example, in the example of FIG. 8, the reference time is 12:00 and the predetermined temperature difference is 5 degrees. According to the temperature history table 166 of FIG. 8, 13: exhaust temperature measured at 00 is 35 degrees, and the exhaust temperature T _y, which is measured in the reference time 12:00, 13: 00 was measured in the exhaust The absolute value of the temperature difference from the temperature Tx is 7 degrees. At this time, the temperature monitoring unit 157 causes the drive condition setting unit 153 to execute the angle adjustment process.

The blower control unit 158 controls the rotation speed, the rotation direction, the blower direction, and the like of the fan 140 included in the blower mechanism 14.

The above is the description of the configuration of the control device 15. The configuration of the control device 15 in FIG. 6 is an example, and is not limited to the configuration of the control device 15 included in the angle adjusting system 1 of the present embodiment as it is.

[Installation example]
Next, an example in which the angle adjusting system 1 of the present embodiment is mounted on the rack 100 will be described with reference to the drawings.

FIG. 9 is a conceptual diagram showing an example in which a plurality of angle adjusting systems 1 are mounted on the rack 100. As shown in FIG. 9, the mounting angles of the plurality of angle adjusting systems 1 are adjusted for each angle adjusting system 1.

Next, an example in which the rack 100 equipped with the angle adjusting system 1 of the present embodiment is arranged indoors will be described with reference to the drawings.

FIG. 10 is a conceptual diagram showing an example in which a plurality of racks 100 equipped with the angle adjusting system 1 are arranged inside the server room 170. In the server room 170 of FIG. 10, the upper side is the ceiling side and the lower side is the floor side. On the ceiling of the server room 170, an intake port 171 for taking in cold air inside the server room 170 and an exhaust port 172 for discharging warm air to the outside of the server room 170 are installed.

FIG. 11 is a conceptual diagram for explaining the flow of cold air and warm air inside the server room 170 in which a plurality of racks 100 equipped with the angle adjusting system 1 are arranged. As shown in FIG. 11, the cold air (white arrow) taken in from the intake port 171 is taken in by the angle adjusting system 1 mounted on the rack 100. The cold air (white arrow) taken into the angle adjustment system 1 is warmed by the heat generated by the operation of the server mounted on the angle adjustment system 1 to become warm air (black arrow), and is discharged from the exhaust port 172.

As shown in FIG. 11, in the angle adjusting system 1 of the present embodiment, since the intake surface 111 of the mounting housing 11 is directed downward and the exhaust surface 112 of the mounting housing 11 is directed upward, warm air having a small specific gravity is directed to the ceiling. It is discharged toward. When the exhaust surface 112 of the mounting housing 11 is directed upward, the air pressure inside the mounting housing 11 decreases with the updraft of warm air that is warmer than the surroundings, so that the intake surface 111 having a relatively high air pressure Cold air is easily taken in from the side of. As a result, the rotation speed of the fan 140 of the blower mechanism 14 can be set low, so that the power consumption and noise of the fan can be reduced.

FIG. 12 is a conceptual diagram for explaining the flow of cold air and warm air inside the server room 170 in which a plurality of racks 100 on which the server 1000 is mounted are arranged by a general mounting method (mounting angle 0 degrees). .. In the general method shown in FIG. 12, since the warm air discharged from the server 1000 is discharged in the horizontal direction, the effect as in the present embodiment using the pressure difference between the inside and the outside of the server 1000 cannot be obtained. ..

FIG. 13 is a conceptual diagram showing another example in which a plurality of racks 100 equipped with the angle adjusting system 1 of the present embodiment are arranged inside the server room 170. In the example of FIG. 13, a lid 181 is provided to prevent cold air and warm air from sneaking above the rack 100. Further, in the example of FIG. 13, a rectifying member 182 is provided to close the gap between the upper and lower portions of the rack 100 and the angle adjusting system 1 and between the adjacent angle adjusting systems 1.

FIG. 14 describes the flow of cold air and warm air inside the server room 170 in which a plurality of racks 100 equipped with the angle adjusting system 1 are arranged with the lid 181 and the rectifying member 182 provided as shown in FIG. It is a conceptual diagram for. As shown in FIG. 14, the cold air (white arrow) taken in from the intake port 171 is taken in by the angle adjusting system 1 mounted on the rack 100. The cold air (white arrow) taken into the angle adjustment system 1 is warmed by the heat generated by the operation of the server mounted on the angle adjustment system 1 to become warm air (black arrow), and is discharged from the exhaust port 172.

When the lid 181 and the rectifying member 182 are provided, the cold air that has passed through the inside of the rack 100 without passing through the inside of the mounting housing 11 is not discharged from the exhaust surface 112. Therefore, the cold air that has passed through the inside of the rack 100 without passing through the inside of the mounting housing 11 and the warm air that has passed through the inside of the mounting housing 11 do not mix with each other. That is, if the lid 181 and the rectifying member 182 are provided as shown in FIGS. 13 and 14, the cold air flow path and the warm air flow path are separated inside the server room 17, so that the entire server room 17 is gas. Circulation efficiency is improved. Further, if the lid 181 and the rectifying member 182 are provided, it is possible to reduce the occurrence of turbulence and noise in the server room 17. That is, if the lid 181 and the rectifying member 182 are provided, the power consumption of the air conditioning system in the server room 17 can be reduced.

The above is a description of an example in which the angle adjusting system 1 of the present embodiment is mounted on the rack 100. Note that FIGS. 9 to 14 are examples, and the method of mounting the angle adjusting system 1 of the present embodiment on the rack 100 is not limited to the same form.

Prior to the angle adjustment process of FIG. 15, the angle adjustment system 1 initializes the control device 15 with the server mounted on the mounting housing 11. In initializing the control device 15, the angle adjusting system 1 inspects the communication status with the sensor 12, clears the user area of the internal memory, inspects the set angle of the angle changing mechanism 13, and initially sets the mounting angle of the angle changing mechanism 13. Conversion (0 degree) and so on. When the control device 15 is initialized, the angle adjustment system 1 operates the fan 140 of the blower mechanism 14 at a predetermined rotation speed.

In FIG. 15, first, the control device 15 acquires air volume data from the sensor 12 (step S111).

Next, the control device 15 records the setting candidate data in which the acquired air volume data value (air volume) is associated with the mounting angle of the mounting housing 11 at that time (step S112). For example, the control device 15 measures the air volume at 1-minute intervals at each mounting angle and records the average value of the air volume in 1 minute. For example, when the mounting angle is changed by 5 degrees in the range of 0 to 90 degrees, the control device 15 records the air volume data at 19 patterns of mounting angles.

When the air volume measurement is not completed at all the set angles (No in step S113), the control device 15 changes the mounting angles of the mounting housing 11 (step S114). After step S114, the process returns to step S111.

On the other hand, when the air volume measurement is completed at all the set angles (Yes in step S113), the control device 15 adjusts the mounting angle of the mounting housing 11 to the angle at which the air volume is maximized (step S115).

Then, the control device 15 acquires temperature data from the sensor 12 and records the temperature history data in which the measurement time of the acquired temperature data is associated with the value (initial temperature) of the temperature data (step S116). When the control device 15 records the temperature history data, the control device 15 notifies the user that the angle adjustment process is completed. The method of notifying that the angle adjustment process is completed is not particularly limited.

The above is the description of the angle adjustment process by the angle adjustment system 1. The angle adjustment process according to the flowchart of FIG. 15 is an example, and the angle adjustment process by the angle adjustment system 1 of the present embodiment is not limited to the method as it is.

[Temperature monitoring process]
FIG. 16 is a flowchart for explaining the temperature monitoring process by the angle adjusting system 1. In the description according to the flowchart of FIG. 16, the control device 15 of the angle adjustment system 1 is the main body of operation.

Prior to the temperature monitoring process of FIG. 16, it is assumed that the power of the server mounted on the mounting housing 11 of the angle adjustment system 1 is turned on.

In FIG. 16, first, the control device 15 waits for 5 minutes (step S121).

Next, the control device 15 acquires temperature data from the sensor 12 and measures the value of the temperature data (exhaust temperature Tx) (step S122).

When the control device 15 has a record of the temperature data value (exhaust temperature Ty) measured 60 minutes ago (Yes in step S123), the control device 15 measures the most recently measured exhaust temperature Tx and 60 minutes ago. Compare with the exhaust temperature Ty (step S124). On the other hand, if there is no record of the temperature data value (exhaust temperature Ty) measured 60 minutes ago (No in step S123), the process returns to step S121.

When the temperature difference between the most recently measured exhaust temperature Tx and the exhaust temperature Ty measured 60 minutes ago is 5 degrees or more (Yes in step S124), the control device 15 performs the angle adjustment process of the flowchart of FIG. Is executed (step S125). On the other hand, when the temperature difference between the most recently measured exhaust temperature Tx and the exhaust temperature Ty measured 60 minutes ago is less than 5 degrees (No in step S124), the process returns to step S121.

When continuing the operation of the server (Yes in step S126), the process returns to step S121. On the other hand, when the operation of the server is terminated (No in step S126), the temperature monitoring process according to the flowchart of FIG. 16 is terminated.

The above is the description of the temperature monitoring process by the angle adjustment system 1. The temperature monitoring process according to the flowchart of FIG. 16 is an example, and the temperature monitoring process by the angle adjusting system 1 of the present embodiment is not limited to the method as it is. Further, the waiting time after starting the fan 140, the standby time, the temperature difference, etc. are guidelines and can be set to arbitrary values.

The above is the description of the operation of the angle adjustment system 1 of the present embodiment. The operation of the angle adjustment system 1 according to the flowcharts of FIGS. 15 to 16 is an example, and the operation of the angle adjustment system 1 of the present embodiment is not limited to the method as it is.

As described above, the angle adjusting system of the present embodiment includes a mounting housing, a blower mechanism, a sensor, an angle changing mechanism, and a control device. An information processing device is mounted inside the mounting housing. The blower mechanism is attached to the mounting housing and generates an air flow inside the mounting housing. The sensor is installed on the exhaust side of the mounting housing and measures the air volume and temperature of the exhaust discharged from the mounting housing. The angle changing mechanism is installed below the mounting housing, and the mounting angle of the mounting housing can be adjusted so that the exhaust side of the mounting housing faces upward. The control device controls an angle changing mechanism that executes an angle adjusting process for changing the mounting angle of the mounting housing based on the air volume measured by the sensor.

In one aspect of the present embodiment, in the angle adjustment process, the control device controls the angle changing mechanism to change the mounting angle of the mounting housing in several stages, and the air volume measured by the sensor at each mounting angle. Record in association with the mounting angle. The control device sets the angle changing mechanism at the mounting angle at which the air volume measured by the sensor is maximum.

In one aspect of the present embodiment, the control device records the temperature measured by the sensor in association with the measurement time after the operation of the information processing device is started. The control device executes the angle adjustment process when the absolute value of the difference between the temperature measured most recently by the sensor and the temperature measurement measured by the sensor at the reference time is equal to or greater than a predetermined value.

In one aspect of this embodiment, the angle changing mechanism has a pedestal, a jack portion, a support portion, and a sliding portion. The pedestal has a storage tank whose upper surface side is open, and a mounting housing is placed on the pedestal.

When the server is tilted so that the exhaust side is higher than the intake side as in the present embodiment, the exhaust warmed by the operation of the server is easily discharged, and the air pressure inside the server housing is lowered, so that cold air is produced. Is more likely to be sucked into the server housing. Therefore, compared to the case where the server is mounted horizontally, when the server is mounted at an angle, the rotation speed of the fan can be set lower to maintain the same temperature. Increasing the power consumption of the fan leads to the power consumption of the server. Further, if the rotation speed of the fan can be reduced, the noise generated by the operation of the fan can be reduced.

As described above, the angle adjustment system of the present embodiment sets the mounting angle of the server to an appropriate angle based on the air volume of the exhaust gas discharged from the server mounted on the rack. Further, the angle adjusting system of the present embodiment sets the mounting angle of the server to a more appropriate angle based on the temperature of the exhaust gas discharged from the server during operation. That is, according to the angle adjusting system of the present embodiment, the mounting angle of the information processing device mounted on the rack can be adjusted to an appropriate angle, and the power consumption of the information processing device can be reduced.

(Second embodiment)
Next, the angle adjustment system according to the second embodiment of the present invention will be described with reference to the drawings. The angle adjusting system of the present embodiment has a different configuration of the angle changing mechanism from that of the first embodiment.

FIG. 17 is a conceptual diagram showing an example of adjusting the mounting angle of the mounting housing 21 of the angle adjusting system 2 of the present embodiment. As shown in FIG. 17, the angle adjusting system 2 includes a mounting housing 21, a sensor 22, an angle changing mechanism 23, a blowing mechanism 24, and a control device (not shown). The mounting housing 21, the sensor 22, the angle changing mechanism 23, and the blower mechanism 24 constitute an angle adjusting device. The mounting housing 21 has an intake surface 211 for taking in cold air and an exhaust surface 212 for discharging warm air warmed by the heat generated by the operation of the server. Since the configurations of the mounting housing 21, the sensor 22, the ventilation mechanism 24, and the control device (not shown) are the same as those in the first embodiment, detailed description thereof will be omitted.

Further, as shown in FIG. 17, the angle changing mechanism 23 has a pedestal 230, a jack portion 231 and a support portion 232, and a sliding portion 233. The pedestal 230 is formed with a storage tank 234 for accommodating the jack portion 231 and the support portion 232. Since the configurations of the pedestal 230, the support portion 232, and the sliding portion 233 are the same as those in the first embodiment, detailed description thereof will be omitted. In the following, the jack portion 231 which is different from the first embodiment will be mainly described.

The jack portion 231 is a mechanism for lifting the mounting housing 21 to change the mounting angle. In the example of FIG. 17, the jack portion 231 has a first end rotatably connected to the inside of the storage tank 234 of the pedestal 230 and a second end rotatably connected to the support portion 232, and expands and contracts. It is a possible rod-shaped member. The shape and operating principle of the jack portion 231 are not limited as long as it operates so as to lift the mounting housing 21. For example, the jack portion 231 is realized by a ram cylinder driven by hydraulic control.

When the jack portion 231 is driven according to the control of the control device, the side of the second end connected to the support portion 232 is lifted with the first end as a fulcrum. Then, when the jack portion 231 extends according to the control of the control device, the side of the second end connected to the support portion 232 is further lifted with the first end as a fulcrum.

FIG. 18 is a conceptual diagram for explaining a state of the angle changing mechanism 23 when the mounting angle of the mounting housing 21 is 0 degrees (also referred to as an initial position). When the mounting angle is 0 degrees, the jack portion 231 and the support portion 232 are stored inside the storage tank 234. When the maximum mounting angles are the same, the jack portion 231 can be stored in a contracted state. Therefore, the angle changing mechanism 23 of the present embodiment has a longer length of the storage tank 234 than the angle changing mechanism 13 of the first embodiment. The length in the direction can be shortened.

FIG. 19 is a conceptual diagram for explaining the state of the angle changing mechanism 23 when the mounting angle of the mounting housing 21 is θ _{1 degree (0 <θ 1} <90). The state of FIG. 19 is a case where the jack portion 231 is not extended. When the mounting angle is _{set to θ 1} degree, the side of the support portion 232 of the jack portion 231 is lifted according to the control of the control device, and the lower end of the mounting housing 21 on the intake surface 211 side slides on the upper surface of the sliding portion 233. .. Then, the mounting housing 21 is held in a state in which the side of the exhaust surface 212 is tilted upward at _{a set mounting angle (θ 1 degree).}

FIG. 20 is a conceptual diagram for explaining the state of the angle changing mechanism 23 when the mounting angle of the mounting housing 21 is θ _{2 degrees (θ 1} <θ ₂ <90). When the mounting angle is _{set to θ 2} degrees, the side of the support portion 232 of the jack portion 231 is lifted according to the control of the control device, and the lower end of the mounting housing 21 on the intake surface 211 side slides on the upper surface of the sliding portion 233. .. When the control device reaches the angle at which the jack portion 231 starts to be extended, the control device controls the jack portion 231 to be extended. Then, the mounting housing 21 is held in a state in which the side of the exhaust surface 212 is tilted upward at _{a set mounting angle (θ 2 degrees).} When the lengths of the storage tanks 234 in the longitudinal direction are the same, the jack portion 231 can be further extended even though the lengths are the same at the time of storage. The mounting angle can be set larger for the angle changing mechanism 23 of the form.

As shown in FIG. 20, when the ventilation mechanism 24 operates with the mounting angle adjusted so that the side of the intake surface 211 faces downward and the side of the exhaust surface 212 faces upward, cold air is taken in from the intake surface 211. The cold air taken in from the intake surface 211 is warmed by the heat generated by the operation of the server. The warmed air is discharged from the exhaust surface 212.

The above is the description of the angle adjusting system 2 of the present embodiment. The configuration of the angle adjustment system 2 of FIGS. 17 to 20 is an example, and the configuration of the angle adjustment system 2 of the present embodiment is not limited to the same configuration.

As described above, the angle adjusting system of the present embodiment has a stretchable jack portion.

In one aspect of this embodiment, the jack portion is a stretchable rod-shaped member having a first end connected to a drive mechanism inside the storage tank and a second end rotatably supported by the support portion. .. The control device adjusts the mounting angle of the mounting housing by combining a control of driving the jack portion so as to lift the second end with the side of the first end as a fulcrum and a control of expanding and contracting the length of the jack portion.

According to the angle adjustment system of the present embodiment, when the maximum mounting angles are the same, the jack portion can be stored in a contracted state, so that the length of the storage tank of the pedestal in the longitudinal direction is shorter than that of the first embodiment. can. Further, according to the angle adjustment system of the present embodiment, when the lengths of the storage tanks of the pedestals in the longitudinal direction are the same, the jack portion can be further extended even though the lengths are the same when stored. The mounting angle can be set larger than that of the embodiment of.

FIG. 23 is a side view showing a state of the angle adjusting device 30 when the mounting angle of the mounting housing 31 is 0 degrees (also referred to as an initial position). In FIG. 23, a state in which a part of the blower mechanism 34 is seen through is shown for easy explanation.

The mounting housing 31 and the ventilation mechanism 34 are mounted on the upper surface of the angle changing mechanism 33. In the present embodiment, the relative coordinate system of the mounting housing 31 is set with the longitudinal direction of the bottom surface of the mounting housing 31 as the x-axis, the lateral direction as the y-axis, and the vertical direction as the z-axis.

The ventilation mechanism 34 takes in cold air inside the mounting housing 31, and discharges warm air warmed by the heat generated by the operation of the server mounted inside the mounting housing 31 to the outside of the mounting housing 31. It has at least one fan 340 for the purpose (FIGS. 22-23). Although FIGS. 22 to 23 show an example in which the blower mechanism 34 has four fans 340, the number and specifications of the fan 340 included in the blower mechanism 34 can be arbitrarily set. In the present embodiment, an example in which the blower mechanism 34 is arranged on the intake surface 311 side of the mounting housing 31 is shown, but the blower mechanism 34 may be arranged on the exhaust surface 312 side of the mounting housing 31.

The fan 340 can change the blowing direction according to the control of the control device 35. In the examples of FIGS. 22 and 23, the direction along the z-axis is set as the central axis, and the blowing direction of the fan 340 is changed in a plane parallel to the xy plane. Each fan 340 included in the blower mechanism 34 can change the blower direction independently of each other.

The air volume data acquisition unit 351 acquires air volume data from the sensor 32. The air volume data acquisition unit 351 stores the setting candidate data in which the acquired air volume data and the mounting angle at that time are associated with each other in the setting candidate data storage unit 352. In the present embodiment, with respect to the relative coordinate system shown in FIGS. 22 and 23, the x-axis is rotated in the + y direction with the direction along the z-axis as the central axis, and the x-axis is rotated in the + θ _f and −y directions.

It may be secured in a storage area (not shown) of the device 35. For example, when the drive condition setting unit 353 performs the angle adjustment process, the exhaust temperature is first measured, and the mounting angle of the mounting housing 31 is set to an angle corresponding to the exhaust temperature by referring to the adjustment history list. , The preparation time can be shortened by omitting the measurement of many patterns for angle adjustment. If the exhaust temperature that is not in the adjustment history list is measured, a new angle adjustment process may be performed and the adjustment history obtained at that time may be added to the adjustment history list.

In the adjustment history table 363, the exhaust temperature measured in the past, the mounting angle when the exhaust temperature is measured, and the blowing direction of the fan 340 are recorded in association with each other. The adjustment history table 363 of FIG. 26 is an example, and the data to be recorded in the adjustment history table 363 is not limited as long as the mounting angle and the blowing direction can be set based on the past adjustment history.

The drive condition setting unit 353 outputs the mounting angle set in the mounting housing 31 to the angle control unit 354 and the air blowing direction set in the fan 340 to the air blowing control unit 358 during the execution of the angle adjustment process. When the angle adjustment process is completed, the drive condition setting unit 353 refers to the setting candidate data stored in the setting candidate data storage unit 352, and acquires the blowing direction and the mounting angle of the fan 340 that maximizes the air volume. The drive condition setting unit 353 outputs the mounting angle at which the air volume is maximum to the angle control unit 354, and outputs the air flow direction at which the air volume is maximum to the air blow control unit 358.

The angle control unit 354 acquires the mounting angle from the drive condition setting unit 353. The angle control unit 354 controls the angle changing mechanism 33 so as to obtain the acquired mounting angle.

The temperature data acquisition unit 355 acquires temperature data from the sensor 32. The temperature data acquisition unit 355 stores the acquired temperature data in the temperature history data storage unit 356 in association with the measurement time of the temperature data. In the present embodiment, the temperature data acquisition unit 355 acquires temperature data while the server mounted on the mounting housing 31 is operating.

The temperature history data storage unit 356 stores the temperature history data in which the measurement time of the temperature data and the temperature measured at the measurement time are associated with each other.

_{When the temperature data (exhaust temperature T x} ) is acquired by the temperature data acquisition unit 355, the temperature monitoring unit 357 refers to the temperature history data storage unit 356. The temperature monitoring unit 357 refers to the temperature history data storage unit 356, and determines the presence or absence of _{temperature data (exhaust temperature Ty} ) measured at a time (reference time) that is a predetermined time before the measurement time of the temperature data. Check. _{When the temperature data (exhaust temperature T x} ) measured at the reference time is stored in the temperature history data storage unit 356, the temperature monitoring unit 357 has measured the most recently measured exhaust temperature T x and the reference time. Compare with the exhaust temperature T _y. And exhaust temperature Tx which is measured most recently, when the temperature difference between the exhaust temperature T _y, which is measured in the reference time is equal to or higher than the predetermined temperature difference, the angle adjustment processing is executed again to the drive condition setting section 353.

The blower control unit 158 acquires the blower direction set in the fan 340 from the drive condition setting unit 353. The blower control unit 158 controls the fan 340 in the direction of the blower acquired from the drive condition setting unit 353. Further, the blower control unit 158 controls the rotation state such as the rotation speed and the rotation direction of the fan 340 included in the blower mechanism 34 according to the control of the drive condition setting unit 353.

The above is the description of the configuration of the control device 35. The configuration of the control device 35 in FIG. 24 is an example, and is not limited to the configuration of the control device 35 included in the angle adjusting system 3 of the present embodiment as it is.

Next, the control device 35 records the setting candidate data in which the acquired air volume data value (air volume) is associated with the mounting angle of the mounting housing 31 at that time (step S312). For example, the control device 35 measures the air volume at 1-minute intervals at each mounting angle and records the average value of the air volume in 1 minute.

If the air volume measurement in all the blowing directions is not completed (No in step S313), the blowing directions of the fan 340 are changed (step S314), and the process returns to step S311. On the other hand, when the air volume measurement in all the blowing directions is completed (Yes in step S313), the blowing directions of the fan 340 are returned to the initial positions (step S315).
