[0010] Hereinafter, embodiments of 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.

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 composed of frame members 4, for example, metal square pillars, and the ends of each frame member 4 are 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 an operator can enter.

The cooling liquid is filled to a height sufficient to immerse the entire substrate placed in the immersion container 5.

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

In the machine room 11, for example, four air-cooling fans 13, a radiator 14, and an outdoor unit 15 are provided on the ceiling as shown in Fig. 2. Note that the number of air-cooling fans 13 is not limited to four and may be changed appropriately as necessary.

As can be seen from the figure, as viewed from the front side FR, for example, an immersion container 5 is provided on the left side, an air-cooled rack 6 and a water-cooled rack 7 are provided on the right side, and a work space 9 is 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 that travels on the ceiling rail 18 transports a server (electronic device).

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

[0019] As shown in Fig. 4, the air-cooling water heat exchanger 20 and the indoor unit 21 are disposed in a cooling flow path 23 through which cooling air flows. Cooling water is guided from a radiator 14 (see Fig. 2) to the air-cooling water heat exchanger 20, and the cooling water after cooling the cooling air 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 is guided to the refrigerant after being decompressed by an expansion valve from the outdoor unit 15 (see FIG. 2), and the evaporated refrigerant is guided to a condenser of 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 cooling air is guided to the air-cooling rack 6 and the water-cooling rack 7 as indicated by arrow A1, and flows out as indicated by arrow A2 after cooling the servers on the air-cooling rack 6 and the water-cooling rack 7. The flowing out cooling 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 container 5, air cooling using an air-cooling rack 6, and water cooling using a water-cooling rack .

[0023] The radiator 14 is, for example, a fin-tube type heat exchanger, and exchanges heat between the air (outside air) circulating outside and the cooling water circulating inside the tubes. The air guided to the radiator 14 is drawn by an air-cooling fan 13. The start / stop control of the radiator 14 is performed 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 cooling water cooled by the radiator 14 is guided through a cooling water outlet pipe 27 to a cooling water tank 29 where it is temporarily stored. A temperature sensor 27T is provided in the cooling water outlet pipe 27, and its output value is sent to the control unit. A pressure sensor 29P is provided in the cooling water 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. The water supply unit 35 is provided in two systems 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 according 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 is switched by operating the automatic on-off valve 35a according 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 is then guided through the return pipe 38 to the cooling water return tank 40 where it is temporarily stored.

[0030] The cooling water stored in the cooling water return tank 40 is returned to the radiator 14 through a cooling water return pipe 45. A temperature sensor 45T and a pressure sensor 45P are provided in the cooling water 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 guided to the immersion vessel 5. The cooling liquid cooled by the cooling water in the immersion water heat exchanger 31 is guided to the immersion vessel 5 through the 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.

[0033] The coolant return pipe 44 is provided with a coolant return section 46 and a flow meter 47. The coolant return section 46 is provided in two systems in parallel, and is provided with an automatic on-off valve 46a, a water pump 46b, a pressure sensor 46P, a strainer 46c, and a manual on-off valve 46d in this order from the upstream side of the coolant flow. The automatic on-off valve 46a operates according 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] Each system of the coolant return unit 46 is switched by operating the automatic on-off valve 46a according 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.

[0035] Between the cooling water tank 29 and the air-cooling water heat exchanger 20, an air-cooling cooling water supply pipe 48 is provided, which is provided with 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 in this order from the upstream side of the cooling water flow. The automatic on-off valve 48a operates according 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 flowmeter 49 and been guided to the air-cooling water heat exchanger 20 is heat exchanged in the air-cooling water heat exchanger 20, and then is guided through the 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 opening and closing 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 server 52 is mounted, and is returned to the air-cooling water heat exchanger 20 again.

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

[0039] Between the cooling water tank 29 and the water-cooling water heat exchanger 33, a cooling water supply pipe 54 for water cooling is provided, which is provided with an automatic opening / closing valve 54a, a water pump 54b, a pressure sensor 54P, a strainer 54c, a manual opening / closing valve 54d, a check valve 54e, and a flow meter 55 in this order from the upstream side of the cooling water flow. The automatic opening / closing valve 54a operates according 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 flowmeter 55 and been guided to the water-cooling water heat exchanger 33 is heat exchanged in the water-cooling water heat exchanger 33, and then is guided through the return pipe 56 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 opening and closing 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 the coolant supply pipe 58. The coolant supply pipe 58 is provided with a temperature sensor 58T and a coolant pump 58a. The output of the temperature sensor 58T is sent to the control unit.

[0042] The coolant in the inlet header 60 is guided to each water-cooled heat sink of the water-cooled rack 7 via multiple supply flow paths 62, where electronic components such as a CPU are water-cooled. After cooling the electronic components in the water-cooled heat sink, the coolant is guided to the outlet header 66 via a return flow path 64. 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), a RAM (Random Access Memory), a ROM (Read Only Memory), and a computer-readable storage medium. A series of processes for realizing various functions is stored in a storage medium or the like in the form of a program, for example, and the CPU reads this program into the RAM or the like and executes information processing and arithmetic processing to realize various functions. The program may be installed in a ROM or other storage medium in advance, may be provided in a state stored in a computer-readable storage medium, or may be distributed via a wired or wireless communication means. The computer-readable storage medium may be a magnetic disk, a magneto-optical disk, a CD-ROM, a DVD-ROM, a semiconductor memory, or the like.

[0044] The container-type data center 1 of the present embodiment described above is used as follows. The container body 2 is provided with an immersion container 5 inside, so that the servers can be immersion cooled. The air-cooled rack 6 is also provided, so that the servers can be air-cooled. Furthermore, the water-cooled rack 7 is also provided, so that the servers can be water-cooled. The user can select three cooling methods according to the amount of heat generated by the server to be used. The cooling method may be selected from any one of the cooling methods, or may be selected from two or all of the cooling methods. When the cooling method is selected, the automatic opening and closing valves 35a, 48a, 54a, and 46a are appropriately controlled to be opened and closed by the control unit. Note that the manual opening and closing valves 35d, 48d, 54d, and 46d are all opened when the container-type data center 1 is in use. For example, when only immersion cooling is selected, the automatic opening and closing valves 35a and 46a are opened, and the automatic opening and closing 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 and the operation of the indoor unit 21 is stopped. In other words, the operation of the air conditioner is stopped and the power of the air conditioner is reduced.

[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. Inside the container body 2, there are provided an immersion vessel 5 for performing immersion cooling, an air-cooled rack 6, and a water-cooled rack 7. 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, it is possible to appropriately cool the electronic devices installed in the air-cooling rack 6 according to the amount of heat generated.

[0050] When the temperature outside the container body 2 is below a predetermined value, the cooling water can be cooled to a desired temperature by the radiator 14, 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 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 by stopping the operation of the air-cooling water heat exchanger 20, power consumption can be reduced.

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

[0052] By providing the roof 70, it is possible to avoid rain and sunlight under the roof, which makes it easier to carry things in 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 loading and unloading is being performed, and is otherwise retracted so as not to impair 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 container (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] Inside the container body, an immersion vessel for immersion cooling, an air-cooled rack, and a water-cooled rack are installed, making it possible to select a cooling method according to the amount of heat generated by electronic devices such as servers in a single container-type data center.

[0056] The container-type data center according to the second aspect of the present disclosure, in the above-mentioned first aspect, is equipped with a vapor compression type cooling device having a compressor for compressing a refrigerant, an expansion valve for expanding the compressed refrigerant, an air-cooled evaporator (21b) for evaporating the expanded refrigerant and cooling the air, and a condenser for condensing the evaporated refrigerant, a cooled water type cooling device having a radiator (14) for discharging sensible heat of the cooling water to the outside of the container body to cool the cooling water, and an air-cooled heat exchanger (20) for cooling 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 the cooling air guided to the air-cooled rack flows, and a control unit for controlling 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 device and the air-cooled heat exchanger of the chilled water cooling device. By controlling the operation of the air-cooled evaporator and the air-cooled heat exchanger, it is possible to appropriately cool the electronic devices installed in the air-cooled rack according to the amount of heat generated by the electronic devices.

[0058] A third aspect of the present disclosure relates to a container-type data center in the above-mentioned second aspect, 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 cooling water can be cooled to a desired temperature by the radiator, so that 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, so the power of the vapor compression cooling device can be reduced. When the temperature outside the container body exceeds a predetermined value, cooling by the air-cooling heat exchanger cannot be expected, so it is preferable to stop the operation of the air-cooling 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, further comprising a roof (70) that can be extended outward from an upper portion of the container body.

[0061] By providing a roof that can be extended outward from the top of the container body, workers can stay under the roof to avoid rain and sunlight, which makes it easier to carry things in and out of the container-type data center. It is preferable that the roof extends outside the container body only when loading and unloading is performed, and is otherwise stowed away so as not to damage the outer shape of the container body. For example, a tarp that can be extended when in use can be used.

[0062] A control method for a container-type data center according to a first aspect of the present disclosure includes a container body, a liquid 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 that compresses a refrigerant, an expansion valve that expands the compressed refrigerant, an air-cooled evaporator that evaporates the expanded refrigerant and cools the air, and a cooling device that condenses the evaporated refrigerant. a cooling water type cooling device including a vapor compression type cooling device having a condenser that discharges sensible heat of the cooling water to the outside of the container body to cool the cooling water, and an air-cooled heat exchanger that cools 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 cooling 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 cooling air guided to the air-cooled rack.
