[0043] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

In addition, the terms "first", "second", and the like are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, features defined as "first", "second", and the like may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0045] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0046] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0047] Bitcoin is a virtual encrypted digital currency in the form of P2P. Point-to-point transmission means a decentralized payment system. Unlike all currencies, Bitcoin does not rely on a specific monetary institution to issue it. It is generated through a large amount of calculations based on a specific algorithm. The Bitcoin economy uses a distributed database composed of many nodes in the entire P2P network to confirm and record all transactions, and uses cryptographic design to ensure the security of all aspects of currency circulation. The decentralized nature of P2P and the algorithm itself can ensure that the currency value cannot be artificially manipulated by producing a large number of Bitcoins. The design based on cryptography can ensure that Bitcoin can only be transferred or paid by the real owner.

[0048] The essence of Bitcoin is actually a special solution generated by a bunch of complex algorithms. A special solution refers to a set of solutions that can be obtained from a finite number of equations, and each special solution can solve the equation and is unique. To use a banknote as an analogy, Bitcoin is the serial number of a banknote. If you know the serial number on a banknote, you own the banknote.

[0049] Computing power (also known as hash rate) is a measure of the processing power of the Bitcoin network. It is the speed at which a computer (CPU) can calculate the output of a hash function. The Bitcoin network must perform intensive mathematical and cryptographic operations for security purposes. For example, when the network reaches a hash rate of 10Th / s, it means that it can perform 10 trillion calculations per second.

[0050] like Figure 1-Figure 5 As shown, the present invention is a liquid-cooled container device, including a box body 20, in which a heat exchange unit 50, a central control cabinet 40, a power distribution cabinet 70, a pure water treatment machine 30 and a cabinet 10 for placing a computing device 80 are arranged;

[0051] The heat exchanger unit 50, the central control cabinet 40 and the pure water treatment machine 30 are arranged at one end of the box body 20, and the cabinet 10 is arranged at the other end. The pure water treatment machine 30 supplies cooling water to the heat exchanger unit 50, and the heat exchanger unit 50 cools down the computing device 80 by liquid cooling. The central control cabinet 40 controls the operation of the electrical components.

[0052] The cabinets 10 are arranged on both sides of the length direction of the container, and the computing equipment 80 is placed inside the cabinets 10 in multiple layers. Each row of cabinets 10 corresponds to a power distribution cabinet 70, and the power distribution cabinet 70 is arranged at one end close to the heat exchange unit 50;

[0053] The maintenance passage 90 is located between two rows of cabinets 10, and the maintenance ports and panels of the computing equipment 80 are all arranged toward the maintenance passage 90. The structure of the present application integrates the heat exchanger unit 50, the central control cabinet 40, the power distribution cabinet 70, the pure water treatment machine 30 and the computing equipment 80 cabinet 10 into one, forming a set of standard products, which is convenient for overall transportation and delivery, and eliminates the on-site construction and assembly links.

[0054] Furthermore, an exhaust fan 60 is provided on one end of the outer side of the box body 20 close to the heat exchanger unit 50, and the computing devices 80 in the cabinet 10 are arranged in rows and columns. The distance between the upper end of the cabinet 10 and the upper top surface of the box body 20 is less than the thickness of a single computing device 80, and the cabinets 10 on both sides are symmetrically arranged; the power distribution cabinet 70 supplies power to the computing device 80 through the PDU power distributor.

[0055] In the actual working process, pure water is used as the liquid cooling medium. The medium is driven by the heat exchange unit 50 and flows into the cooling tower outside the container. After being cooled by the closed cooling tower, the medium flows back to the computing device 80 inside the container. The coolant passes through the liquid cooling plate inside the computing device 80 and undergoes heat exchange, thereby reducing the temperature of the liquid cooling plate. At the same time, the temperature of the liquid cooling medium increases. The high-temperature liquid medium is then driven by the heat exchange unit 50 to enter the closed cooling tower outside the container and cool down. The cycle is repeated in sequence, and the liquid cooling plate undergoes heat exchange with the heat-generating chip attached to the surface, thereby achieving the purpose of reducing the chip temperature.

[0056] Heat exchange formula:

[0057] Q = Δt*m*C;

[0058] C is the specific heat capacity of the coolant; m is the mass of the coolant; Δt is the temperature difference (before and after heating and heat release);

[0059] The cooling liquid absorbs heat Q1=Δt1*m1*C1 when passing through the liquid cooling plate inside the computing device 80, where Δt1 is the temperature difference before and after the cooling liquid passes through the liquid cooling plate.

[0060] The heat dissipated into the air by the coolant after closed cooling is Q2=Δt2*m2*C2, where Δt2 is the temperature difference before and after the coolant passes through the closed tower.

[0061] Since the entire cooling system is a closed-loop system, the flow rate of the coolant flowing through the computing device 80 and the cooling tower outside the container is consistent, and the specific heat capacity is consistent, so m1=m2, C1=C2, and from the principle of conservation of energy: Q1=Q2, it can be concluded that Δt1=Δt2.

[0062] The hot liquid discharged from the computing equipment 80 flows back to the heat exchange unit 50, and then is cooled by the cold source outside the container, and flows back to the computing equipment 80 again, and circulates in sequence; the computing equipment 80 cabinets 10 are arranged in two rows, which can be arranged densely, and the maintenance channel is in the middle of the container, which is convenient for disassembly and maintenance; the whole set of liquid cooling container equipment has complete functional modules, which is a self-contained product, easy to transport, and saves the on-site installation process.

The plurality of computing power modules 3 constitute a computing power center, and a heat dissipation fan 8 with multiple layers stacked up and down is arranged on the other side. The computing power module 3 is cooled by a liquid cooling module 7. The liquid cooling module 7 is a front-to-back pull-out structure relative to the main body 1. The computing power module and the liquid cooling module are conventional modules on the market. According to the structure of the present application, liquid cooling can be adopted.

[0067] A first main water pipe 4 is provided on one side of the front end of the main body 1, and a second main water pipe 5 is provided on the other end; a plurality of parallel hoses 6 are provided on the first main water pipe 4, one end of the hose 6 is connected with the first main water pipe 4, and the other end enters the liquid cooling module 7, and then passes out from the side away from the first main water pipe 4 and is connected with the second main water pipe 5. One liquid cooling module 7 corresponds to one hose 6, and the cooling medium flows through the hose 6 and the liquid cooling module 7 to cool the computing power module 3, thereby realizing the liquid cooling requirement.

[0068] Preferably, a handle 71 for easy pushing and pulling is provided at the front end of each liquid cooling module 7, which is convenient for pushing and pulling and maintenance. During the maintenance process, the operation of other liquid cooling modules 7 is not affected, and the independence is strong. The liquid cooling module 7 is a blade-type liquid cooling module 7, and the cold plate shell in the liquid cooling module 7 is in contact with the chip in the computing power module 3 for heat conduction.

[0069] Preferably, the first main water pipe 4 and the second main water pipe 5 are both vertically arranged, and the lower ends are arc-shaped, and are both connected to a drain valve 9, which extends horizontally to the front end of the main body 1, and the upper end connecting ports of the first main water pipe 4 and the second main water pipe 5 are horizontally arranged. The horizontally arranged structure facilitates the setting and connection of pipelines, and can be directly installed horizontally, reducing operations in the vertical direction and improving work efficiency. It can also be set in other directions, and the structure of the present application can be realized.

[0070] Preferably, multiple hoses 6 are connected in parallel with the first main water pipe 4, and multiple hoses 6 are arranged in parallel up and down. A first valve 61 for controlling the on and off of the hose 6 is provided between the hose 6 and the first main water pipe 4, and a second valve 62 for controlling the passage of the hose 6 is provided between the hose 6 and the second main water pipe 5. The hose 6 is connected to the liquid cooling module 7 through a quick-plug connector 72. The quick-plug connector 72 is provided, and the connection is convenient and fast. The quick-plug connector 72 is a commonly used connector on the market with various specifications, which can meet the matching requirements of hoses 6 of various specifications. In addition, the first hose 6 and the second hose 6 are provided at the same time, and the software on the same layer is controlled, which is convenient for operating the independent liquid cooling modules 7, and they are highly independent of each other.

[0071] Preferably, the hose 6 extends from the first main water pipe 4 in a direction away from the main body 1, then forms a first arch and enters the liquid cooling module 7. The cooling fan 8 is arranged in the area of ​​the first arch. After the hose 6 exits the liquid cooling module 7, it forms a second arch and enters the second main water pipe 5. The first valve 61 is located in the straight section of the first arch, and the second valve 62 is located in the straight section of the second arch. One of the first main water pipe 4 and the second main water pipe 5 serves as an inlet pipe, and the other serves as an outlet pipe. The hoses 6 are both arranged at the front end of the main body 1, do not occupy the internal space of the cabinet, and the pipeline replacement is convenient. In the present application, the terminal box and the computing power module 3 are installed in the front and maintained in the front, eliminating the operating space on the rear side of the cabinet. Moreover, after adopting this structure, it can be set against the wall, occupying less space, with a more compact structure and convenient maintenance.

[0072] Preferably, the structure of the first valve 61 is the same as that of the second valve 62. A driving handle 611 is provided at the upper end of the first valve 61. The driving handle 611 is a fan-type structure, including four vertically and evenly distributed L-shaped sheet metals. This makes it convenient to adjust the position of the driving handle. By inserting a rod-shaped structure and cooperating with two of the L-shaped sheet metals, the driving handle 611 can be rotated to complete the rotation of the first valve 61 or the second valve 62 and adjust the flow of the cooling medium.

[0073] Preferably, the materials of the hose 6 include but are not limited to the following: hydrogenated nitrile rubber, low-temperature resistant fluororubber, low-phenyl silicone rubber, silicone rubber, fluorosilicone rubber, FEP tube, FPA tube, Teflon tube or nylon tube. The main hose 6 can withstand a certain low temperature and has stable chemical properties. The hose 6 can be purchased directly from the market. The inner diameter of the first main water pipe 4 is the same as the specification of the second main water pipe 5, ensuring the same water inlet and outlet, and less prone to medium disorder. The size is stable and the cooling effect is good. The inner diameter of the hose 6 is less than 1 / 3 of the inner diameter of the first main water pipe 4, ensuring the first main water pipe 4 or the second main water pipe 5 to supply the medium of multiple hoses 6.

[0074] Preferably, the cooling medium in the hose 6 is water or low-temperature resistant antifreeze liquid, which is specifically selected according to the local minimum temperature in winter. Currently, it is to prevent the cooling liquid in the internal pipeline of the equipment from freezing and cracking the pipeline.

[0075] Preferably, the cooling fan 8 is responsible for 8%-12% of the heat dissipation, and the rest of the heat is cooled by liquid cooling. The combination of the two greatly reduces the noise of air cooling.

[0076] Preferably, the main body is an assembled frame structure with low cost and high strength.

[0077] In actual use, this application mainly uses air conditioning to cool the existing servers. If a single standard cabinet meets the cooling requirements, the maximum heat generation cannot exceed 20KW. In this application, the coolant can directly enter the liquid cooling heat sink inside the server, that is, the cold plate shell in the liquid cooling module 7 is in contact with the chip in the computing power module 3 for heat conduction, which greatly improves the heat dissipation efficiency.

[0078] The coolant enters through the first main water pipe 4 on the main body 1, and then is diverted to the inside of the blade-type liquid cooling module 7 through the hose 6. The liquid cooling module 7 includes a liquid cooling plate, and a pipe for the circulation of the cooling medium is arranged on the liquid cooling plate. The circulating cooling medium cools the heat-generating chip. After the coolant is heated, it is collected on the second main water pipe 5 through the hose 6, and finally discharged from the cabinet through the upper end of the second main water pipe 5. The residual heat inside the blade-type liquid cooling module 7 is discharged out of the cabinet by the cooling fan 8 arranged on the main body 1. In the present application, the medium can also enter from the second main water pipe 5 and be discharged from the first main water pipe 4. There is no limitation on the direction. It is mainly the process of medium circulation, which can play a role in cooling.

[0079] The blade-type liquid cooling modules 7 are all independent, and their maintenance process is to close the first valve 61 and the second valve 62 on the front and rear inlet and outlet water hoses 6 of the corresponding blade-type liquid cooling modules 7, remove the quick-plug connector 72 connected to the hose 6, pull out the hose, drain the coolant, and remove the blade-type liquid cooling module 7 to be repaired. The blade-type liquid cooling module 7 can be installed in the opposite way to the above process. Maintenance is quick and convenient with low cost. In the present application, the first valve and the second valve can also be replaced by a two-way cut-off quick-plug connector. By adopting the two-way cut-off quick plug solution, the hose and the module do not need to be disassembled, and can be transported, maintained, and installed as a whole. This operation is more convenient; in the present application, manual valves can also be used, or other valves with on-off functions or other equivalent structures can achieve the functions in the present application.

[0080] If the entire cabinet needs drainage and maintenance, you must first close the inlet and outlet valves connecting the two main water pipes to the external water system to ensure that the water flow between the main pipe and the external pipeline is disconnected, open the drain valve 9 at the bottom of the first main water pipe 4 and the second main water pipe 5, that is, close and remove the drain valve 9 connecting the cabinet to the outside world, and all the water inside the cabinet can be discharged from top to bottom, which is convenient for maintenance and discharge of all coolant in the cabinet.

[0081] The overall depth of this application is about 500-600mm, which is relatively shallow and has high heat dissipation efficiency. A single cabinet can achieve a heat dissipation of 80KW. Compared with compressor refrigeration, the cold plate shell is in contact with the chip in the computing power module 3 for heat conduction, eliminating the intermediate air compression link, which is more energy-efficient; the noise is reduced, and the air-cooled server relies on a large air volume fan to reduce the chip temperature. Liquid cooling is used in this application for cooling, and only about 10% of the remaining heat needs to be taken away by the cooling fan 8. The order of magnitude reduction in the wind speed of the cooling fan 8 greatly reduces the noise of the cooling fan 8; the cooling medium in the soft circuit is water, or low-temperature resistant antifreeze, which is specifically selected according to the local minimum temperature in winter. At present, it is to prevent the coolant in the internal pipeline of the equipment from freezing and cracking the pipeline.

[0082] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
