Description

Technical Field

[0001] The present invention relates to a cooling system for a container-type mining center and a container-type mining center equipped with the cooling system.

Background Art

[0002] Since virtual currency mining consumes a large amount of power, mining in an area with low power costs is suitable. A container-type mining center (also referred to as a container-type data center or a container-type computing center) can be mounted on a vehicle and transported via a general road, so its installation location can be changed flexibly. In addition, compared with a data center installed as a building, it has the characteristic that it can be easily installed at low cost in a short period of time.

[0003] On the other hand, a large number of servers housed in a container generate a lot of heat during operation. The electronic components that make up the server are extremely vulnerable to heat, and there is a risk of runaway or damage to semiconductor chips due to heat stress at high temperatures. Appropriate temperature management of the server is essential to protect precision equipment from such heat damage and perform efficient mining.

[0004] Patent Document 1 discloses a system for managing the temperature of a room (the entire room) in which servers are installed by supplying cold air from a coil unit into the server room.

Summary of the Invention

Problems to be Solved by the Invention

[0006] However, in the cooling system described in Patent Document 1, some servers may not be sufficiently cooled and could become overheated (hot spots) due to factors such as recirculation of hot air caused by turbulent airflow in the room and uneven distribution of processing load. If such overheating occurs, the overall processing performance of the server may decrease, or specific components may be damaged by thermal stress, potentially leading to system shutdown.

[0007] To solve the above problems, this invention provides a cooling system that suppresses uneven cooling and maintains a uniform temperature for multiple servers housed in a containerized mining center, thereby preventing overheating and enabling all servers to operate stably under nearly identical temperature conditions. [Means for solving the problem]

[0008] The container-type mining center of the present invention comprises a container, a plurality of water-cooled servers housed inside the container and mounted on racks, a cooling water supply device that supplies cooling water to the water-cooled servers, and a circulation pump that circulates the circulating cooling water flowing between the water-cooled servers and the cooling water supply device, in a cooling system for a container-type mining center. The main pipe for carrying cooling water, A supply-side branch pipe that branches in parallel from the main pipe and leads the cooling water to the water-cooled server, A drain-side branch pipe for draining the return cooling water after the water-cooled server has cooled, A main drain pipe through which the return cooling water from the drain side branch pipe flows, A supply volume adjustment valve adjusts the amount of cooling water supplied from the supply side branch pipe according to the temperature of the water-cooled server, The water-cooled server is characterized by being equipped with a drain volume adjustment valve that adjusts the amount of return cooling water drained according to the temperature of the water-cooled server. [Effects of the Invention]

[0009] According to this invention, it is possible to suppress uneven cooling of multiple servers housed in a container-type mining center, maintain a uniform temperature to prevent overheating of the servers, and enable all servers to operate stably at nearly the same temperature.

[Figure 5] This is an enlarged view of a water-cooled server in a container-type mining center according to an embodiment of the present invention. [Modes for carrying out the invention]

[0011] The container-type mining center of this invention will be described below based on embodiments. The drawings schematically represent the container-type mining center, its components, and its peripheral components, and the dimensions and dimensional ratios shown in the drawings do not necessarily correspond to the actual dimensions and dimensional ratios. Unless otherwise specified, for convenience, directions such as up and down are indicated based on the orientation of the container-type mining center shown in Figure 1. Duplicate explanations will be omitted as appropriate, and the same reference numerals may be assigned to the same components. Figure 1(a) is a side view of a containerized mining center, and Figure 1(b) is a front view of a containerized mining center. The container 10 consists of a floor section 16, a ceiling section 17, and wall sections 18, which form the interior space of the container 10 and have a door 11 for entering and exiting the container 10.

[0012] A water-cooled server 12 is installed in the server room 19 of the container 10. The container 10 includes transport containers and other types of containers that can be loaded onto vehicles such as trucks for transport, and preferably has an insulated structure that allows for temperature control.

[0013] Figure 2 is a plan view of the server room 19 of a container-type mining center 100 according to an embodiment of the present invention. As shown in Figure 2, racks 13 are provided in the longitudinal direction inside the container 10, and water-cooled servers 12 are placed on the racks 13. The racks 13 are small compared to the floor area inside the container 10, and there are passages 14 between the racks 13. Power lines and communication lines are wired to the water-cooled servers 12 from a power distribution / communication panel 15 via the racks 13.

[0014] Figure 3 is a front view of a container-type mining center 100 according to an embodiment of the present invention. The racks 13 are made of steel, aluminum, fiber-reinforced plastic (FRP), etc. Inside the racks 13, water-cooled servers 12 are installed on each level, and the main piping 20 and main drainage pipe 21, which will be described later, are housed there.

[0015] Figure 4 is a piping diagram of a container-type mining center 100 according to an embodiment of the present invention. Figure 5 is an enlarged view of a water-cooled server 12 in the container-type mining center 100 according to an embodiment of the present invention. As shown in Figures 4 and 5, the container-type mining center 100, which is one embodiment of the present invention, is provided with a main pipe 20 through which cooling water c for cooling a plurality of water-cooled servers 12 flows, a supply-side branch pipe 22 that branches in parallel from the main pipe 20 to supply cooling water c to the water-cooled servers, a drain-side branch pipe 23 that drains the return cooling water rc that has cooled the water-cooled servers 12, and a main drain pipe 21 through which the return cooling water rc from the drain-side branch pipe 23 flows. Cooling water c cooled by a cooling water supply device (not shown) is supplied to the main pipe 20 from a supply port 24. The cooling water c is supplied to the plurality of water-cooled servers 12 through the main pipe 20 by the operation of a circulation pump 27. The return cooling water rc, which has undergone heat exchange in each water-cooled server 12, is ultimately returned to the cooling water supply device from the outlet 30 by a circulation pump, and is recirculated after heat dissipation.

[0016] The circulation pump 27 is equipped with a compensator 31 and a replenishment tank 32. The compensator 31 absorbs expansion and contraction of the piping due to temperature changes and pressure fluctuations, preventing damage to the piping and connections. The replenishment tank 32 stabilizes the cooling water volume, separates bubbles, and mitigates pressure fluctuations. The main drain pipe 21 is equipped with the circulation pump 27, a temperature sensor 25, and a pressure sensor 26. The temperature sensor 25 detects the water temperature and, based on the detection result, controls the operation of the cooling water supply device, which is a cooling system, and adjusts the circulating water volume to ensure that the water-cooled server 12 operates within a predetermined temperature range. The pressure sensor 26 constantly monitors the system pressure and controls or stops the circulation pump 27 in the event of abnormal pressure. The return cooling water from the circulation pump 27 is cooled to a predetermined temperature by a cooling water supply device (not shown) and supplied to the server 12 as cooling water c.

[0017] The supply-side branch pipe 22 branches off from the main pipe 20 in parallel and supplies cooling water c to each of the plurality of water-cooled servers 12. By branching off in parallel from the main pipe 20, each water-cooled server 12 receives the cooling water c directly from the same system, so that all the water-cooled servers 12 can be operated under substantially the same temperature conditions. As described above, the return cooling water rc heat-exchanged in each water-cooled server 12 is collected into the main drain pipe 21 through the drain-side branch pipe 23 and returned to the cooling water supply device from the water outlet 30.

[0018] The supply-side branch pipe 22 is provided with a supply amount adjustment valve 28 for adjusting the supply amount according to the temperature of each water-cooled server 12. The drain-side branch pipe 23 is provided with a drain amount adjustment valve 29 for adjusting the drain amount according to the temperature of each water-cooled server 12. In the container-type mining center 100 according to the embodiment of the present invention, butterfly valves are used for the supply amount adjustment valve 28 and the drain amount adjustment valve 29. The supply amount adjustment valve 28 and the drain amount adjustment valve 29 are adjusted in valve opening degree based on temperature or flow rate during the test run or during operation. By adjusting the valve opening degrees of the supply amount adjustment valve 28 and the drain amount adjustment valve 29, the deviation of the flow rate of the cooling water c due to the difference in pipe length and supply resistance is eliminated, and the cooling water supply amounts supplied to the plurality of water-cooled servers 12 are equalized.

[0019] Thus, in the container-type mining center 100 according to the embodiment of the present invention, by adjusting the supply amount of the cooling water supplied to the water-cooled server 12, overheating of the water-cooled server 12 can be prevented, and all the water-cooled servers 12 can be operated at substantially the same temperature.
