Technical Field

[0001] The utility model belongs to the field of pipelines, and relates to the shunt of media in pipelines and the online adjustment of flow rate, in particular to an online heat distribution pipeline structure and a server integration with such a pipeline. Background Art

[0002] In the era of the explosion of big data, especially with the development of AI technology, the amount of data has increased exponentially. Moreover, the stored files occupy more and more memory space. For the security of data, the timeliness of storage, the convenience of calling, etc., most companies have their own enterprise servers for the timely upload, storage and backup of data files, the transfer of data files, etc. Servers are crucial to enterprises, carrying all the electronic data information of enterprises. In the current information era where big data is king, once the server breaks down, it will directly affect the normal operation and management of enterprises. The stable operation of the server is of vital importance.

[0003] Due to the importance of servers, many enterprises set up special areas or rooms for servers and at the same time match corresponding cooling measures to ensure the good continuous operation of highly integrated servers. During the process of high-speed continuous operation and cooling of servers, a large amount of heat is dissipated. At present, most of this heat is directly discharged into the atmosphere, and at the same time, suitable cooling measures need to be matched for cooling. The cooling equipment consumes a large amount of energy, and the dissipated heat is directly discharged, and the heat cannot be recovered in time, resulting in a large amount of energy consumption in the operation of the server. In addition to the cost of the server equipment itself, the operating energy consumption also becomes part of the enterprise cost.

[0004] At present, many enterprises consider recycling and reusing the heat dissipated by servers to meet the daily heat supply demand. During the process of waste heat utilization, multiple pipelines need to be laid, occupying as little space as possible, and it is necessary to meet the usage requirements in different scenarios according to the actual heat source demand situation. However, there is currently no mature pipeline structure for reference. Summary of the Utility Model

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood through specific situations.

[0037] The following will make a detailed description of the specific embodiments of the present utility model in conjunction with the accompanying drawings.

[0038] The working principle of the dry cooler is mainly based on the principle of heat exchange. Specifically, there is a circulating refrigerant flowing through the pipes inside the dry cooler, and these pipes are usually designed with a structure for efficient heat dissipation. When the high-temperature refrigerant flows through these pipes, the fan or natural wind outside the pipes will blow air over the surface of the pipes to form heat exchange. In this process, the refrigerant transfers heat to the outside air through the pipe wall, causing the temperature of the refrigerant to decrease, thereby achieving the cooling effect. The outside air becomes warmer because it absorbs the heat of the refrigerant and is then discharged or naturally dissipated. This heat exchange process continues, and the refrigerant circulates inside the dry cooler, continuously releasing heat, thereby maintaining its temperature at a relatively low level. Therefore, the dry cooler can effectively reduce the temperature of the liquid and achieve the purpose of cooling. It should be noted that there is no water consumption during the operation of the dry cooler, so its water-saving property is very obvious. At the same time, since the heat exchange is carried out through air, the dry cooler will not generate water mist or water droplets during operation, enabling it to be applied in some environments with high humidity requirements. Generally speaking, the dry cooler uses the principle of heat exchange and the temperature difference between air and refrigerant to achieve the cooling effect, and it is an efficient and energy-saving cooling device.

[0039] The plate heat exchanger component is a highly efficient heat exchanger component formed by stacking a series of metal sheets with a certain corrugated shape. It is composed of many stamped corrugated thin plates at a certain interval, sealed around by gaskets, and tightly overlapped and pressed by a frame and a compression spiral. The four corner holes of the plate and the gasket form the fluid distribution pipe and the collecting pipe, and at the same time reasonably separate the hot and cold fluids, allowing them to flow in the flow channels on both sides of each plate respectively, and exchanging heat through the plates. Thin rectangular channels are formed between various plates for heat exchange through the plates. The plate heat exchanger component is an ideal device for heat exchange between liquid-liquid and liquid-vapor. It has high heat exchange efficiency, small heat loss, compact and lightweight structure, small floor area, wide application, and long service life.

[0040] Such as Figures 1-8As shown in the figure, the utility model is an on-line heat distribution pipeline structure and a server integration with this pipeline, which is mainly used in cooperation with a server cabinet to form an integrated server cabinet capable of recovering and utilizing waste heat. For the cabinet-type liquid cooling system, it provides a suitable working environment for liquid-cooled servers, ensuring the stable operation of liquid-cooled servers under good working conditions. The traditional liquid-cooled server cycle is to connect to a cold source and dissipate heat into the atmosphere, while this device can recover and supply heat from the heat generated by the operation of the server. The medium is transported to the heat consumption point through devices such as a water pump and a plate heat exchanger assembly, and the heat supply output is controlled through devices such as a three-way valve, a flow meter, and a frequency converter. The total heat supply is counted through a heat meter.

[0041] An integrated server cabinet capable of recovering and utilizing waste heat, which is mostly used in the independent cabinet structure below 100K, includes multiple servers 1, a cooling distribution unit, and a control component. Multiple servers can be laid out in multiple rows and columns on the computer positions;

[0042] The cooling distribution unit (CDD) includes a primary circulation pipeline, and the waste heat utilization module includes a secondary circulation pipeline. The primary circulation pipeline and the secondary circulation pipeline realize the on-line adjustment of the water flow in the primary circulation pipeline and the secondary circulation pipeline through an electric three-way regulating valve, so as to realize the switching of the whole system among multiple modes such as primary temperature control, waste heat utilization mode, and secondary temperature control.

[0043] The primary circulation pipeline serves as a cooling source, and through the circulation of the medium, it cools and dissipates heat from multiple servers;

[0044] The secondary circulation pipeline, as a bypass branch of the liquid cooling system, is used for waste heat recovery to meet the heat supply requirements of components with external heat source needs;

[0045] It also includes a plate heat exchanger assembly. The medium after the primary circulation pipeline is heated by the server serves as the heat source supply of the plate heat exchanger assembly. After heat exchange through the plate heat exchanger assembly, the cooled medium flows back to the primary circulation pipeline, and at the same time, the heated medium serves as the heat source supply source in the secondary circulation pipeline.

[0046] More preferably, the structure of this application is a cabinet type structure, including a cabinet body, which adopts a highly integrated structure and is divided into upper and lower parts. Multiple servers are located in the upper part. The length and width of the cooling distribution unit are equal to the length and width of the cabinet, and the height is compressed as much as possible to leave space for the layout of the servers, occupying the lower half of the cabinet, and assembled into a skid for convenient and rapid disassembly and assembly.

[0047] The primary circulation pipeline is arranged on the back of the cabinet and is arranged in a return flow pattern. A soft connection is provided between the pipeline and the cooling distribution unit (CDU) to prevent the vibration of the CDU from affecting the stability of the server operation. The control component is mainly electrical, arranged on the upper part of the front of the cabinet, far away from the pipeline and the CDU and isolated and partitioned. The main equipment includes a main switch, branch switches, a frequency converter, a PLC module, a screen, terminal blocks, cables, and busbars.

[0048] The structural layout of this application follows the principles of proximity and non-interference. The principle of proximity is to minimize interfaces, cables, pipelines, etc., and relevant parts should be adjacent. The principle of non-interference is to minimize or eliminate intersections between different partitions. On this basis, make detailed partitions, determine the limit space of each part, and finally arrange and combine according to the limit space to form an integrated and highly integrated cabinet. Then design by partition, design the server, control components, primary circulation pipeline and secondary circulation pipeline separately, and finally assemble. Finally, make combined adjustments, assemble all partitions according to the original plan, check for interference and rationality, and make adjustments.

[0049] For the selection of pipelines, pipe fittings and valve groups in the whole structure, round up according to the flow rate of the primary circulation pipeline and the secondary circulation pipeline, and select pipelines with economic specific frictional resistance. The riser uses square pipes, which can make more effective use of space while having similar specific frictional resistance; the pipe fittings and valve groups are selected with the same pipe diameter.

[0050] In the whole structure, the length and width are equal to or less than the length and width of the cabinet, and the height is compressed as much as possible to leave space for the arrangement of servers. The electric three-way throttle valve is installed at the water inlet of the heat exchange component. Select a diverging three-way valve. If it is installed at the water outlet of the plate heat exchanger component, select a converging three-way valve.

[0051] The structural layout for Embodiment 1 - RACKCAB is as follows: The primary circulation pump and the secondary circulation pump are arranged parallel to each other vertically and are set at one side close to the edge of the cabinet body. The dry cooler fan and the plate heat exchanger component are arranged vertically and parallel to each other on the same side and are located on the side of the cabinet body far from the primary circulation pump. After the primary circulation pump and the secondary circulation pump are arranged vertically at intervals, the total vertical height space occupied is not greater than the total height of the plate heat exchanger component or the air cooler fan, and the middle position on both sides is used for laying pipelines; the primary circulation pump is located above the secondary circulation pump.

[0052] The inlet end and the outlet end are centrally and horizontally laid and arranged in parallel, located at the bottommost of the CDU structure. From left to right, they are the cold water inlet 5 of the primary circulation pipeline, the hot water return port 6 of the primary circulation pipeline, the hot water outlet 7 of the secondary circulation pipeline, and the cold water return port 8 of the secondary circulation pipeline. Path of the primary circulation pipeline: The cooling medium enters the primary circulation pipeline through the cold water inlet of the primary circulation pipeline, cools multiple servers, the medium heats up, and then the medium passes through the electric three-way regulating valve. Part of the heated medium enters the plate heat exchanger assembly, and the other part of the heated medium returns to the dry cooler fan through the three-way valve, thus forming the primary circulation pipeline. Secondary circulation pipeline: The heated medium that enters the plate heat exchanger assembly exchanges heat, and the plate heat exchanger assembly outputs the heated medium, which enters the secondary circulation pipeline as a heat source supply to achieve waste heat recovery and reuse. During the reuse process, the medium in the secondary circulation pipeline cools down and returns to the plate heat exchanger assembly through the secondary circulation pump for heat exchange again, and the part of waste heat utilization forms the secondary circulation pipeline. Further, the upper end of the plate heat exchanger assembly is connected to the hot water return port of the primary circulation pipeline and the hot water outlet of the secondary circulation pipeline, and the lower end is connected to the cold water inlet of the primary circulation pipeline and the cold water return port of the secondary circulation pipeline. The upper end has a heat source inlet and a heat source outlet, and the lower end has a low-temperature inlet and a low-temperature outlet, meeting the maximum heat exchange demand of the upper and lower paths and having a high heat exchange efficiency.

[0053] The structural layout for Embodiment 2-HYDROCAB is as follows: The primary circulation pump and the secondary circulation pump are arranged horizontally in parallel, located at one side of the cabinet close to the edge. The dry cooler fan is arranged horizontally, and the center line in the length direction is parallel to the axis of the primary circulation pump. The plate heat exchanger assembly is arranged above the dry cooler fan, and both are arranged on one side of the cabinet in the length direction. The tails of the primary circulation pump and the secondary circulation pump are close to the rear end of the cabinet. The positions on the side of the plate heat exchanger assembly and the front end of the cabinet are used for laying pipelines.

[0054] The inlet end and the outlet end are centrally and horizontally laid and arranged in parallel, located at the lowermost end of the CDU structure. From left to right, they are the cold water return port of the secondary circulation pipeline, the hot water outlet of the secondary circulation pipeline, the cold water inlet of the primary circulation pipeline, and the hot water return port of the primary circulation pipeline. The path of the primary circulation pipeline: The cooling medium enters the primary circulation pipeline through the cold water inlet of the primary circulation pipeline, cools down multiple servers, and then the medium heats up. The heated medium enters the plate heat exchanger assembly and serves as a heat source for heat exchange. After heat exchange, the high-temperature medium after heat exchange passes through the electric three-way regulating valve. Part of the heated medium enters the plate heat exchanger assembly, and the other part of the heated medium flows back to the dry cooler fan through the three-way valve, thus forming the primary circulation pipeline. The secondary circulation pipeline: The heated medium that enters the plate heat exchanger assembly exchanges heat, and the plate heat exchanger assembly outputs the heated medium, which serves as a heat source and enters the secondary circulation pipeline to realize the recovery and reuse of waste heat. During the reuse process, the medium in the secondary circulation pipeline cools down and flows back to the plate heat exchanger assembly through the secondary circulation pump for re-heat exchange, and the part of waste heat utilization forms the secondary circulation pipeline. Further, the front end of the plate heat exchanger assembly close to the cabinet is connected to the hot water return port of the primary circulation pipeline and the hot water outlet of the secondary circulation pipeline, and the rear end is connected to the cold water inlet of the primary circulation pipeline and the cold water return port of the secondary circulation pipeline. The front end has a heat source inlet and a heat source outlet, and the rear end has a low-temperature inlet and a low-temperature outlet, meeting the maximum heat exchange demand of the path, and having high heat exchange efficiency.

[0055] More preferably, the cabinet body is of a frame structure, with multiple servers installed inside. There are gaps between adjacent servers for the arrangement of the primary circulation water circuit. The primary circulation pipeline includes but is not limited to the dry cooler fan, and other liquid-cooled servers can also be used as long as they can provide a cooling medium supply source. It also includes the primary circulation main inlet pipeline 2 and the primary circulation main return pipeline 3. One server corresponds to one water inlet branch and one water outlet branch. The primary circulation main inlet pipeline simultaneously enters the cooling areas of multiple servers through multiple water inlet branches, and then flows back to the primary circulation main return pipeline through the water outlet branches. Control valves for water flow switches are provided on each water inlet branch and each water outlet branch. The opening and closing of each valve can be determined and adjusted according to the actual number of servers arranged in the cabinet, meeting the cooling requirements of different scales of servers, ensuring targeted and efficient cooling, and avoiding unnecessary energy consumption waste.

[0056] It should be noted that the cooling medium in this application is water, and other cooling media can also be used without specific limitations as long as the cooling requirements are met. The outlet described in this application refers to the liquid outlet end, and water is one of the implementation modes.

[0057] More preferably, in the primary circulation main water inlet pipeline, a first valve V003, a primary water circulation flowmeter FIT01, and a primary water inlet temperature signal meter TT01 are sequentially provided from the dry cooler fan end to the server end. In the primary circulation main water return pipeline, a primary water return temperature signal meter TT02, a primary circulation water pump P01, an electric three-way regulating valve V001, and a second valve V002 are sequentially provided from the server end to the dry cooler fan end. The primary water circulation flowmeter FIT01 feeds back a signal to the control component. The control component compares the feedback value of the primary water circulation flowmeter FIT01 with the set target flow through the PID algorithm module, and then adjusts the frequency of the primary circulation water pump so that the value of the primary water circulation flowmeter FIT01 catches up with the set target flow.

[0058] One connection of the electric three-way regulating valve V001 is connected to one of the secondary circulation water inlet pipes of the secondary circulation pipeline. The secondary circulation pipeline further includes a plate heat exchanger assembly. The water inlet end of the plate heat exchanger assembly includes two inputs. One is a secondary circulation water inlet pipe connected to the electric three-way regulating valve V001, which serves as the heat source for heat exchange. The other is a water source supply pipe connected to the outside, which is the water source after cooling by waste heat utilization. That is, the medium in the secondary circulation pipeline is cooled and then returns to the plate heat exchanger assembly through the secondary circulation water pump for further heat exchange and external supply of hot water. A secondary circulation water pump P02 and a secondary water return temperature signal meter TT11 are provided on the secondary circulation main water inlet pipe. The secondary water return temperature signal meter TT11 feeds back a signal to the control component. At the same time, an outdoor temperature signal meter TT21 and an indoor temperature signal meter TT22 are provided, that is, the temperature in the heating room. The outdoor temperature signal meter TT21 and the indoor temperature signal meter TT22 are both electrically connected to the control component to feed back the real-time temperature to the control component. The water outlet end of the plate heat exchanger assembly is also divided into two branches. One branch returns the cooled medium to the primary circulation main water inlet pipeline in the primary circulation pipeline and is connected between the first valve V003 and the primary water circulation flowmeter FIT01. The other branch is connected to an external heat source demand component. Waste heat utilization can also be used in multiple fields, as detailed below.

[0059] Heating: Any area with heating requirements such as apartments, villas, shopping malls, restaurants, office buildings, stadiums, theaters, factories, warehouses, agricultural greenhouses, fresh air preheating, etc. These areas are mostly areas where people gather, have certain requirements for heating, and in the current social environment, the large data processing volume in areas where people are concentrated, and server cabinets are mostly set up. The technical solution of this application can be adopted to recover waste heat again;

[0060] Hot water: Domestic hot water, pool heating, fish pond heating, etc., to meet the daily water use needs;

[0061] Others: Drying, high-temperature sterilization, steam generator preheating, and other parts that require heat.

[0062] More preferably, when the heat source supply of the primary circulation pipeline cannot meet the heat recovery requirement, the heat source supply pipe connected to the outside can be used as a supplement, so that the entire heat recovery utilization operates well and meets the usage requirements. Of course, there is no external heat source set in the structure of this application, and the heat of the server itself is fully utilized for recovery, which is environmentally friendly.

[0063] For convenience of explanation, each signal or numerical code is described in the following table, and multiple control modes can be realized.

[0064]

[0065] The control method of the primary flow control is as follows:

[0066] Manually set a target flow value FIT91, and this value is required to be displayed on the setting screen.

[0067] Compare the values of FIT91 and FIT01, and adjust the frequency of the primary circulation pump P01 through the PID algorithm module to make FIT01 infinitely close to FIT91.

[0074] The above three modes are in parallel and can be manually switched.

[0075] The terminal temperature control system is as follows:

[0076] Manually set an indoor temperature target value TT96 (±2), and this value and range should be displayed on the setting screen;

[0080] The embodiments are as follows.

[0081] Cabinet external dimensions: Similar to a common server cabinet for placement, width * depth * height = 800 * 1000 * 2200mm

[0082] Server load: 10 - 15 servers, occupying the upper half of the cabinet;

[0083] Cooling Distribution Unit (CDU): The length and width are equal to those of the cabinet, and the height is compressed as much as possible to leave space for server layout. It occupies the lower half of the cabinet and is assembled into a skid to form a skid-mounted structure, which is convenient for quick disassembly and assembly as a component, facilitating quick machine relocation and quick assembly, and also convenient for overall replacement, maintenance and repair. The main equipment includes a primary circulation pump, a secondary circulation pump, a plate heat exchanger assembly, a water storage tank, a make-up water pump, a flow meter, an electric three-way regulating valve, a filter, a valve group and pipelines, etc.

[0084] Pipelines, pipe fittings and valve groups are determined.

[0085] DN50 pipes are selected for the pipelines for the economic specific frictional resistance, and square pipes of 40×40mm should be selected for the risers. While the specific frictional resistance is close, the space can be utilized more effectively. Valves of the same diameter as the pipelines are selected, the flow meters are the same as the valves, and the same pipeline diameter is selected, and the electric three-way regulating valves also select the same pipeline diameter.

[0086] The above structure of the present application can be used for small-scale (below 100kW) liquid-cooled server deployment, i.e., an integrated independent cabinet; it can also be used for large-scale liquid-cooled server deployment, i.e., parallel cabinet operation, and the waste heat utilization can also be used in multiple fields, as detailed below.

[0087] Heating: Any area with heating requirements such as apartments, villas, shopping malls, restaurants, office buildings, stadiums, theaters, factories, warehouses, agricultural greenhouses, fresh air preheating, etc. These areas are mostly places where people gather and have certain requirements for heating. Moreover, in the current social environment, the large data processing volume in areas where people are concentrated requires the installation of server cabinets. The technical solution of this application can be adopted to recover waste heat again;

[0088] Hot water: Domestic hot water, pool heating, fish pond heating, etc., to meet the daily water use needs;

[0089] Others: Other parts that require heat, such as drying, high-temperature sterilization, steam generator preheating, etc.

[0090] During the application process of enterprises, it can meet heating and daily hot water supply, etc. Hot water supply is essential for many office areas or factories. For factories with production workshops or accommodation areas, it can meet the daily bathing needs of employees, especially in winter. At the same time, water heating can be used for office heating, which is especially suitable for areas where heating is not convenient, and there is no additional energy consumption. It fully recovers waste heat and improves the environment.

[0091] Compared with the existing heating products on the market, such as electric boilers and wall-mounted boilers, the advantages of this application are as follows.

[0092] 1. Energy-saving and efficient. Since the overall thermal efficiency is as high as 97%, it can be considered that one portion of energy can meet the two requirements of server operation and heat at the same time;

[0093] 2. Low carbon emissions. The double carbon emissions of server operation + heating are changed to one portion;

[0094] 3. Additional income. Server computing power income can be generated while heating;

[0095] 4. Highly integrated and easy to install. The built-in pump station simplifies the on-site installation process, and it can be put into production immediately after connecting the cables and pipes.

[0096] A detailed description of an embodiment of the present utility model has been given above, but the content described is only the preferred embodiment of the present utility model and cannot be considered as limiting the scope of implementation of the present utility model. All equivalent changes and improvements made according to the scope of the application of the present utility model should still fall within the scope covered by the patent of the present utility model.
