[0003] Patent No. 6293355

[0004] In Patent Document 1, an air-cooling system is adopted in which servers installed in a server rack are cooled by bringing air into contact with them. However, depending on the amount of heat generated by the electronic devices to be cooled, air-cooling may not be sufficient, and a water-cooling system using a water-cooled heat sink or a liquid-immersion system in which the electronic devices are immersed in a cooling liquid may be required.

[0005] The present disclosure has been made in consideration of the above circumstances, and aims to provide a container-type data center and a control method thereof that can appropriately cool electronic devices according to the amount of heat generated by the electronic devices to be cooled.

Fig. 2 is a perspective view showing the rear side of the container-type data center of Fig. 1. Fig. 3 is a plan view of the container-type data center of Fig. 1. Fig. 4 is a front view schematically showing the flow of cooling air flowing through air-cooled racks and water-cooled racks. Fig. 5 is a schematic view showing a cooling circuit. Fig. 6 is a perspective view showing a modified example.

[0010] Hereinafter, an embodiment according to the present disclosure will be described with reference to the drawings. FIG. 1 shows a container-type data center 1. The container-type data center 1 has a standard container shape that is portable. Note that FIG. 1 shows the container-type data center 1 with the plates that make up the walls removed so that the interior of the container-type data center 1 can be seen.

[0011] The container-type data center 1 includes a container body 2 having an external shape that is, for example, a rectangular parallelepiped. The width direction (longitudinal direction, x direction) of the container body 2 is, for example, 12 ft (3.66 m) or less. The depth direction (y direction) of the container body 2 is smaller than the dimension in the width direction. Each side of the rectangular parallelepiped container body 2 is formed by frame members 4, for example, metal square pillars, and the ends of each frame member 4 are respectively fixed.

[0012] When the container body 2 is viewed from the front FR side, for example, an immersion vessel 5 for performing immersion cooling is provided on the left side, and an air-cooled rack 6 and a water-cooled rack 7 are provided on the right side. A distribution board 8 is provided on the front FR side of the air-cooled rack 6. The central space when viewed from the front FR is used as a work space 9 where workers can enter.

[0013] The immersion vessel 5 is a bottomed vessel that stores a cooling liquid therein. The cooling liquid is an electrically insulating liquid, such as silicone oil. The cooling liquid is filled to a height sufficient to completely immerse the substrate placed in the immersion vessel 5.

[0014] A plurality of substrates are placed inside the immersion vessel 5. Each substrate is, for example, a substrate that constitutes a server, and is arranged at a predetermined interval with its longitudinal direction oriented vertically. A plurality of electronic components that constitute the server, such as a CPU, a power supply unit, memory, storage such as a hard disk or SSD (Solid State Drive), and a communication unit, are mounted on the substrate. These electronic components generate heat during operation of the server and are cooled by the coolant.

[0015] A machinery room 11 is provided on the rear side RR of the container body 2. As shown in Fig. 2, the machinery room 11 is provided with, for example, four air-cooling fans 13, a radiator 14, and an outdoor unit 15 on the ceiling. Note that the number of air-cooling fans 13 is not limited to four and can be changed as needed.

[0016] 3 shows a plan view of the above-described container-type data center 1. As can be seen from the drawing, as viewed from the front side FR, for example, an immersion container 5 is provided on the left side, and air-cooled racks 6 and water-cooled racks 7 are provided on the right side, with a work space 9 provided in the center of these. For example, a machine room 11 is provided on the rear side RR.

[0017] A ceiling rail 18 is provided above the immersion container 5. A crane running on the ceiling rail 18 transports a server (electronic device).

[0018] Above the air-cooled rack 6 and the water-cooled rack 7, an air-cooling water heat exchanger (air-cooling heat exchanger) 20 and an air conditioner indoor unit 21 are provided.

[0019] As shown in Fig. 4, the air-cooling water heat exchanger 20 and the indoor unit 21 are arranged in a cooling flow path 23 through which cooling air flows. Cooling water is introduced from the radiator 14 (see Fig. 2) to the air-cooling water heat exchanger 20, and after cooling the cooling air, the cooling water is returned to the radiator 14. The indoor unit 21 is provided with an indoor unit fan 21a and an evaporator (air-cooling evaporator) 21b.

[0020] The evaporator 21b receives refrigerant that has been decompressed by an expansion valve from the outdoor unit 15 (see FIG. 2), and the evaporated refrigerant is then guided to a condenser in the outdoor unit 15. The outdoor unit 15 is provided with a compressor that compresses the refrigerant, an expansion valve that expands the compressed refrigerant, and a condenser that condenses the evaporated refrigerant. In this way, the indoor unit 21 and the outdoor unit 15 form an air conditioner (vapor compression cooling device).

[0021] After passing through the air-cooling water heat exchanger 20 and the indoor unit 21, the cooled air is guided to the air-cooled rack 6 and the water-cooled rack 7 as indicated by arrow A1, and after cooling the servers on the air-cooled rack 6 and the water-cooled rack 7, it flows out as indicated by arrow A2. The outflowing cooled air is guided again to the air-cooling water heat exchanger 20 and the indoor unit 21 as indicated by arrow A3, and circulates.

[0022] FIG. 5 shows a cooling circuit for performing immersion cooling using the above-mentioned immersion vessel 5, air cooling using an air-cooling rack 6, and water cooling using a water-cooling rack 7.

[0023] The radiator 14 is, for example, a fin-and-tube heat exchanger, and exchanges heat between the air circulating outside (outside air) and the coolant circulating inside the tubes. The air guided to the radiator 14 is drawn by an air-cooling fan 13. The radiator 14 is controlled, for example, to start and stop, by a control unit (not shown).

[0024] An outside air temperature sensor 25 that measures the temperature of outside air is provided near the radiator 14. The output of the outside air temperature sensor 25 is sent to the control unit.

[0025] The coolant cooled by the radiator 14 is guided through a coolant outlet pipe 27 to a coolant tank 29 where it is temporarily stored. A temperature sensor 27T is provided in the coolant outlet pipe 27, and its output value is sent to the control unit. A pressure sensor 29P is provided in the coolant tank 29, and its output value is sent to the control unit.

[0026] Cooling water is guided from the cooling water tank 29 to the immersion water heat exchanger 31 , the air-cooling water heat exchanger 20 , and the water-cooling water heat exchanger 33 .

[0027] A water supply unit 35 and a flow meter 36 are provided between the cooling water tank 29 and the immersion water heat exchanger 31. Two water supply units 35 are provided in parallel, and from the upstream side of the cooling water flow, an automatic on-off valve 35a, a water pump 35b, a pressure sensor 35P, a strainer 35c, and a manual on-off valve 35d are provided. The automatic on-off valve 35a operates in response to a command from the control unit. The outputs of the pressure sensor 35P and the flow meter 36 are sent to the control unit.

[0028] Each system of the water supply unit 35 can be switched by operating an automatic on-off valve 35a in response to a command from the control unit. In other words, when one system is in use, the other system serves as a backup, providing redundancy.

[0029] The cooling water that has passed through the flow meter 36 and been guided to the immersion water heat exchanger 31 undergoes heat exchange in the immersion water heat exchanger 31, and then passes through the return pipe 38 and is guided to the cooling water return tank 40 where it is temporarily stored.

[0030] The coolant stored in the coolant return tank 40 is returned to the radiator 14 through a coolant return pipe 45. A temperature sensor 45T and a pressure sensor 45P are provided in the coolant return pipe 45, and the outputs of each are sent to the control unit.

[0031] In the immersion water heat exchanger 31, heat is exchanged between the cooling water and the cooling liquid introduced into the immersion vessel 5. The cooling liquid cooled by the cooling water in the immersion water heat exchanger 31 is introduced into the immersion vessel 5 through a cooling liquid supply pipe 42. A temperature sensor 42T is provided in the cooling liquid supply pipe 42, and its output is sent to the control unit. A temperature sensor 5T that measures the temperature of the cooling liquid is provided in the immersion vessel 5, and its output is sent to the control unit.

[0032] A coolant return pipe 44 that returns the coolant to the immersion water heat exchanger 31 is connected to the immersion vessel 5. A temperature sensor 44T is provided in the coolant return pipe 44, and the output thereof is sent to the control unit.

[0033] The coolant return pipe 44 is provided with a coolant return unit 46 and a flow meter 47. The coolant return unit 46 is provided in two parallel systems, and is provided with, in order from the upstream side of the coolant flow, an automatic on-off valve 46a, a water pump 46b, a pressure sensor 46P, a strainer 46c, and a manual on-off valve 46d. The automatic on-off valve 46a operates in response to a command from the control unit. The outputs of the pressure sensor 46P and the flow meter 47 are sent to the control unit.

[0034] The cooling liquid return section 46 has its respective systems switched by operating an automatic on-off valve 46a in response to a command from the control section. In other words, when one system is in use, the other system serves as a backup, providing redundancy.

[0035] An air-cooling cooling water supply pipe 48 is provided between the cooling water tank 29 and the air-cooling water heat exchanger 20, and is provided with, in order from the upstream side of the cooling water flow, an automatic on-off valve 48a, a water pump 48b, a pressure sensor 48P, a strainer 48c, a manual on-off valve 48d, a check valve 48e, and a flow meter 49. The automatic on-off valve 48a operates in response to a command from the control unit. The outputs of the pressure sensor 48P and the flow meter 49 are sent to the control unit.

[0036] The cooling water that has passed through the flow meter 49 and been guided to the air-cooling water heat exchanger 20 undergoes heat exchange in the air-cooling water heat exchanger 20, and is then guided through a return pipe 51 to the cooling water return tank 40 where it is temporarily stored. The return pipe 51 is provided with a temperature sensor 51T, a check valve 51a, and an automatic on-off valve 51b. The output of the temperature sensor 51T is sent to the control unit.

[0037] As described with reference to Fig. 4, an indoor unit 21 is provided downstream of the cooling air flow of the air-cooling water heat exchanger 20. The cooling air flowing out of the indoor unit 21 flows through the air-cooling rack 6 on which the servers 52 are mounted, and is returned to the air-cooling water heat exchanger 20.

[0038] Temperature sensors 20T, 21T, and 6T are provided downstream of the air-cooling water heat exchanger 20, the indoor unit 21, and the air-cooling rack 6, respectively, and their outputs are transmitted to the control unit.

[0039] A water-cooling cooling water supply pipe 54 is provided between the cooling water tank 29 and the water-cooling water heat exchanger 33, and is provided with, in order from the upstream side of the cooling water flow, an automatic on-off valve 54a, a water pump 54b, a pressure sensor 54P, a strainer 54c, a manual on-off valve 54d, a check valve 54e, and a flow meter 55. The automatic on-off valve 54a operates in response to a command from the control unit. The outputs of the pressure sensor 54P and the flow meter 55 are sent to the control unit.

[0040] The cooling water that has passed through the flow meter 55 and been guided to the water-cooling water heat exchanger 33 undergoes heat exchange in the water-cooling water heat exchanger 33, and then passes through a return pipe 56 and is guided to the cooling water return tank 40 where it is temporarily stored. The return pipe 56 is provided with a temperature sensor 56T, a check valve 56a, and an automatic on-off valve 56b. The output of the temperature sensor 56T is sent to the control unit.

[0041] In the water-cooling water heat exchanger 33, heat is exchanged between the cooling water and the heat sink coolant that is guided to the water-cooled heat sink of the water-cooled rack 7. The heat sink coolant that has been cooled in the water-cooling water heat exchanger 33 is guided to the inlet header 60 through a coolant supply pipe 58. A temperature sensor 58T and a coolant pump 58a are provided in the coolant supply pipe 58. The output of the temperature sensor 58T is sent to the control unit.

[0042] The coolant in the inlet header 60 is guided via multiple supply flow paths 62 to each water-cooled heat sink of the water-cooled rack 7, where electronic components such as CPUs are water-cooled. After cooling the electronic components in the water-cooled heat sink, the coolant is guided via return flow paths 64 to the outlet header 66. The coolant stored in the outlet header 66 passes through a coolant return pipe 68 and is guided again to the water-cooling water heat exchanger 33. A temperature sensor 68T is provided in the coolant return pipe 68, and its output is sent to the control unit.

[0043] The control unit is composed of, for example, a CPU (Central Processing Unit), RAM (Random Access Memory), ROM (Read Only Memory), and a computer-readable storage medium. A series of processes for realizing various functions is stored in a storage medium, for example, in the form of a program. The CPU reads this program into RAM and executes information processing and arithmetic operations to realize various functions. The program may be pre-installed in a ROM or other storage medium, provided in a state stored in a computer-readable storage medium, or distributed via wired or wireless communication means. Examples of computer-readable storage media include magnetic disks, magneto-optical disks, CD-ROMs, DVD-ROMs, and semiconductor memories.

[0044] The container-type data center 1 of the present embodiment described above is used as follows. The container body 2 is equipped with an immersion vessel 5, allowing servers to be immersion cooled. The air-cooled racks 6 are also equipped, allowing servers to be air-cooled. The water-cooled racks 7 are also equipped, allowing servers to be water-cooled. A user can select from three cooling methods depending on the amount of heat generated by the servers being used. The cooling method may be selected from one, two, or all of the cooling methods. When a cooling method is selected, the automatic on-off valves 35a, 48a, 54a, and 46a are appropriately controlled to open and close by a control unit. Note that the manual on-off valves 35d, 48d, 54d, and 46d are all open when the container-type data center 1 is in use. For example, when only immersion cooling is selected, the automatic on-off valves 35a and 46a are opened, and the automatic on-off valves 48a and 54a are closed.

[0045] When the air-cooling rack 6 is used, the air-cooling water heat exchanger 20 and the indoor unit 21 are controlled as follows.

[0046] When the temperature outside the container body 2 (output value of the outside air temperature sensor 25) is equal to or lower than a predetermined value, the air-cooling water heat exchanger 20 is used to stop the operation of the indoor unit 21. In other words, the operation of the air conditioner is stopped, and the air conditioner is operated with reduced power.

[0047] When the temperature outside the container body 2 exceeds a predetermined value, the operation of the air-cooling water heat exchanger 20 is stopped, and the indoor unit 21 is operated to cool the cooling air to a desired value by the air conditioner.

[0048] The effects of the present embodiment described above are as follows: The immersion vessel 5 for performing immersion cooling, the air-cooled rack 6, and the water-cooled rack 7 are provided inside the container body 2. This makes it possible to select a cooling method in one container-type data center 1 according to the amount of heat generated by electronic devices such as servers.

[0049] The cooling air guided to the air-cooling rack 6 is cooled by the air conditioner's evaporator 21b and the air-cooling water heat exchanger 20. By controlling the operation of the air conditioner's evaporator 21b and the air-cooling water heat exchanger 20, appropriate cooling can be performed according to the heat generation amount of the electronic devices installed on the air-cooling rack 6.

[0050] When the temperature outside the container body 2 is below a predetermined value, the radiator 14 can cool the cooling water to a desired temperature, so cooling is performed using the air-cooling water heat exchanger 20. In this case, the load on the evaporator 21b can be reduced or its operation can be stopped, so the power consumption of the air conditioner can be reduced. When the temperature outside the container body 2 exceeds a predetermined value, cooling by the air-cooling water heat exchanger 20 cannot be expected, so stopping the operation of the air-cooling water heat exchanger 20 can reduce power consumption.

[0051] As shown in FIG. 6, a roof 70 that can be extended outward from the top of the container body 2 may be provided.

[0052] By providing the roof 70, it is possible to protect from rain and sunlight underneath the roof. This makes it easier to carry things into and out of the container-type data center 1. It is preferable that the roof 70 extends outward from the container body 2 only when carrying things in and out, and is otherwise retracted so as not to damage the outer shape of the container body. For example, a tarp with a cloth that can be extended when in use can be used.

[0053] The container-type data center and the control method thereof described in each of the above-described embodiments can be understood, for example, as follows.

[0054] A container-type data center (1) according to a first aspect of the present disclosure comprises a container body (2), a liquid immersion vessel (5) provided inside the container body and storing a cooling liquid for immersing and cooling electronic devices, an air-cooled rack (6) provided inside the container body and through which cooling air passes, and a water-cooled rack (7) provided inside the container body and equipped with a water-cooled heat sink that is attached in contact with heat-generating parts of the electronic devices.

[0055] The container body is equipped with an immersion vessel for immersion cooling, an air-cooled rack, and a water-cooled rack, allowing a single container-type data center to select a cooling method depending on the heat generation of electronic devices such as servers.

[0056] The container-type data center according to the second aspect of the present disclosure is the same as that of the first aspect, and further comprises: a vapor compression cooling device including a compressor that compresses a refrigerant, an expansion valve that expands the compressed refrigerant, an air-cooled evaporator (21b) that evaporates the expanded refrigerant and cools the air, and a condenser that condenses the evaporated refrigerant; a chilled water cooling device including a radiator (14) that cools the cooling water by discharging sensible heat of the cooling water to the outside of the container body, and an air-cooled heat exchanger (20) that cools the air with the cooling water cooled by the radiator; a cooling flow path (23) in which the air-cooled evaporator and the air-cooled heat exchanger are arranged and through which cooled air guided to the air-cooled rack circulates; and a control unit that controls the operation of the air-cooled evaporator and the air-cooled heat exchanger.

[0057] The cooling air introduced into the air-cooled rack is cooled by the air-cooled evaporator of the vapor compression cooling system and the air-cooled heat exchanger of the chilled water cooling system. By controlling the operation of the air-cooled evaporator and the air-cooled heat exchanger, it is possible to provide appropriate cooling according to the heat generation amount of the electronic devices installed in the air-cooled rack.

[0058] A container-type data center according to a third aspect of the present disclosure is the second aspect described above, wherein the control unit operates the air-cooled heat exchanger to cool the cooling air guided to the air-cooled rack when the temperature outside the container body is below a predetermined value.

[0059] When the temperature outside the container body (e.g., outside air temperature) is below a predetermined value, the radiator can cool the cooling water to the desired temperature, so cooling is performed using the air-cooled heat exchanger. In this case, the load on the air-cooled evaporator can be reduced or its operation can be stopped, thereby reducing the power required for the vapor compression cooling system. When the temperature outside the container body exceeds a predetermined value, cooling by the air-cooled heat exchanger cannot be expected, so it is preferable to stop the operation of the air-cooled heat exchanger.

[0060] A container-type data center according to a fourth aspect of the present disclosure is any one of the first to third aspects, and is provided with a roof (70) that can be extended outward from the top of the container body.

[0061] By providing a roof that can be extended outward from the top of the container body, people can be sheltered from rain and sunlight underneath the roof. This facilitates the loading and unloading of items into and out of the container-type data center. It is preferable that the roof only extends outward from the container body when loading and unloading items are required, and is otherwise retracted so as not to damage the external shape of the container body. For example, a tarp that can be extended when in use can be used.

[0062] A method for controlling a container-type data center according to a first aspect of the present disclosure includes a container body, an immersion vessel provided inside the container body and storing a cooling liquid for immersing and cooling electronic devices, an air-cooled rack provided inside the container body and through which cooling air passes, a water-cooled rack provided inside the container body and equipped with a water-cooled heat sink attached in contact with a heat-generating portion of the electronic devices, a compressor for compressing a refrigerant, an expansion valve for expanding the compressed refrigerant, an air-cooled evaporator for evaporating the expanded refrigerant and cooling the air, and an air-cooled evaporator for condensing the evaporated refrigerant. a chilled water cooling system including a vapor compression type cooling system having a condenser that cools the cooling water by discharging sensible heat of the cooling water to the outside of the container body, and an air-cooled heat exchanger that cools the air with the cooling water cooled by the radiator; and a cooling flow path in which the air-cooled evaporator and the air-cooled heat exchanger are arranged and through which cooled air guided to the air-cooled rack flows, wherein when the temperature outside the container body is below a predetermined value, the air-cooled heat exchanger is operated to cool the cooled air guided to the air-cooled rack.
