Description

Technical Field

[0001] This invention relates to the field of cooling equipment technology, and more particularly to a cooling water device and a data center. Background Technology

[0002] Industrial equipment and its supporting data processing equipment generate a large amount of heat during operation. Heat buildup can negatively impact equipment performance, shorten its lifespan, and even cause malfunctions. Taking data processing equipment as an example, excessively high temperatures can lead to decreased computing power, abnormal operation, and in severe cases, system crashes and hardware damage. Therefore, cooling water systems are commonly installed. Conventional cooling water systems operate using an internal and external circulation heat exchange method. The external circulation directly cools the heat-generating equipment, while the internal circulation exchanges heat with the external circulation, ultimately dissipating the heat to the outside through the internal circulation, thus achieving cooling.

[0003] In scenarios such as the start-up of cooling water system transfer pumps and changes in heat exchange load, pressure fluctuations and unstable medium flow are prone to occur. Existing cooling water systems typically have limited pressure stabilization capabilities. When the transfer pump is first started, the pressure in the external circulation pipeline is not yet stable and is prone to sudden rises or falls. When the heat exchange load changes, it can easily cause turbulent medium flow, leading to uneven cooling medium velocity, flow fluctuations, reduced heat exchange efficiency, and impact on cooling performance. These problems often rely on introducing additional buffers or pressure stabilizing structures. However, these structures are usually large and require significant installation space, hindering the overall compact design of the system and making them difficult to implement in space-constrained applications. Furthermore, the connection path between external buffers or pressure stabilizing structures and the internal cooling water system is long, limiting their response speed and effectiveness to transient pressure changes, making it difficult to balance system compactness and operational stability. Therefore, how to achieve pressure stability and volume regulation during pipeline operation without significantly increasing system structural space has become a pressing technical problem in this field.

[0020] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0021] In the description of this invention, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component positioned centrally in the connection.

[0022] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] Example 1: This embodiment provides a cooling water device for cooling external equipment. Figures 1-3 As shown, the cooling water device includes an internal circulation pipeline and a medium delivery pipeline. A second cooling medium flows through the internal circulation pipeline, serving as a heat exchange cooling circuit. A first cooling medium to be cooled flows through the medium delivery pipeline, serving as a heat exchange circuit. The first cooling medium can flow to external equipment to be cooled for cooling. In a specific embodiment, the first cooling medium is one of water, ethylene glycol aqueous solution, propylene glycol aqueous solution, heat transfer oil, and industrial antifreeze. The second cooling medium is also one of water, ethylene glycol aqueous solution, propylene glycol aqueous solution, heat transfer oil, and industrial antifreeze. The internal circulation pipeline and the medium delivery pipeline exchange heat in a heat exchanger 4 to cool the first cooling medium in the medium delivery pipeline. The heat exchanger 4 is a common component of the internal circulation pipeline and the medium delivery pipeline. The heat exchanger 4 has a heat exchange medium inlet 43 and a heat exchange medium outlet 44 located in the medium delivery pipeline, and a heat exchange internal circulation inlet 41 and a heat exchange internal circulation outlet 42 located in the internal circulation pipeline.

[0024] Combination Figure 4As shown, the internal circulation pipeline includes a compressor 1, a condenser 2, a throttle valve 3, and a heat exchanger 4. The heat exchanger internal circulation outlet 42, compressor 1, condenser 2, throttle valve 3, and heat exchanger internal circulation inlet 41 are connected in sequence to form a circulation, thus forming an internal circulation pipeline. The compressor 1 is used to compress the second cooling medium, increasing its pressure and temperature to provide power for the circulation of the second cooling medium in the internal circulation pipeline. The condenser 2 is used to cool and dissipate heat from the high-temperature and high-pressure second cooling medium, causing it to change from a gaseous state to a liquid state. The throttle valve 3 is used to throttle and reduce the pressure of the liquid second cooling medium, making it a low-temperature and low-pressure gas-liquid mixture. The heat exchanger 4 is used to realize the heat transfer between the second cooling medium and the first cooling medium, completing the cooling of the first cooling medium. In a specific embodiment, the heat exchanger 4 is a plate heat exchanger 4, which has high heat exchange efficiency and a compact structure. The cooling water device also includes a fan 21, which is positioned directly opposite the condenser 2. The fan 21 can accelerate the airflow around the condenser 2, enhance the heat dissipation capacity of the condenser 2, and improve the refrigeration cycle efficiency.

[0025] Combination Figures 5-7 As shown, the medium delivery pipeline includes a medium storage tank 5 connected to the heat exchanger 4 and a delivery pump 61 connected to the medium storage tank 5. The delivery pump 61 provides circulation power for the first cooling medium, driving it to flow within the medium delivery pipeline. The upper part of the medium storage tank 5 contains compressible gas, and the lower part stores the first cooling medium. The compressible gas is used to buffer pipeline pressure fluctuations and, in conjunction with pressure pulses, achieve pressure stabilization. In a specific embodiment, the compressible gas can be air or an inert gas; the initial pressure of the compressible gas is greater than or equal to standard atmospheric pressure. The medium storage tank 5 is connected to a replenishment branch 71 for replenishing the first cooling medium into the medium storage tank 5. A diaphragm pump 62 is installed on the replenishment branch 71. The diaphragm pump 62 generates pressure pulses during operation and acts on the medium storage tank 5 to stabilize the pressure in the area where the medium storage tank 5 connects to the delivery pump 61.

[0026] In practice, after the transfer pump 61 starts, the first cooling medium stored in the lower part of the driving medium storage tank 5 flows in the medium delivery pipeline. After passing through the heat exchanger 4 and completing heat exchange with the internal circulation pipeline, it flows back to the medium storage tank 5. When the pressure of the first cooling medium fluctuates during circulation in the pipeline, the compressible gas in the upper part of the medium storage tank 5 can buffer the pipeline pressure fluctuations generated during the circulation of the first cooling medium in real time. At the same time, the diaphragm pump 62 on the replenishment branch 71 starts to operate, and the pressure pulse generated by it acts on the inside of the medium storage tank 5. It is transmitted to the connection point of the transfer pump 61 through the first cooling medium stored in the medium storage tank 5, stabilizing the pressure in the area where the tank is connected to the transfer pump 61. In addition, when the liquid level of the first cooling medium in the medium storage tank 5 is insufficient, the first cooling medium can also be replenished into the tank through the diaphragm pump 62 on the replenishment branch 71 to ensure that the circulation heat exchange of the entire medium delivery pipeline continues. The cooling water device described in this embodiment does not require additional independent pressure stabilizing tanks, accumulators, or other dedicated pressure stabilizing components. It can simultaneously achieve multiple functions such as pressure buffering, pulse pressure stabilization, and medium replenishment simply by cooperating with the medium storage tank 5 and the diaphragm pump 62. This enables multi-purpose utilization of a single structure, simplifies the pipeline structure, and reduces the overall complexity of the device.

[0027] Furthermore, when the transfer pump 61 is first started, the pressure in the medium delivery pipeline has not yet reached a stable state, and unstable situations such as sudden pressure rises or falls are prone to occur. In addition, when the heat exchanger load of the heat exchanger 4 changes or the local resistance of the pipeline fluctuates, it can cause unstable symptoms such as turbulent medium flow and the generation of eddies. Eddies can further cause uneven flow velocity and flow fluctuations of the first cooling medium, and may even cause the compressible gas in the upper part of the medium storage tank 5 to be drawn into the first cooling medium, forming a medium gas mixing phenomenon, which affects the sufficient contact of heat exchange, reduces heat exchange efficiency, and affects the cooling effect. At this time, the buffering effect of the compressible gas, in conjunction with the pressure pulse regulation of the diaphragm pump 62, can quickly balance the pressure in the storage tank, ensuring the stable operation of the transfer pump 61 and the normal progress of heat exchange.

[0028] In one preferred embodiment, the lower side wall of the medium storage tank 5 is provided with a second interface 52 that communicates with the delivery pump 61. Figure 7 As shown, the media storage tank 5 has a fifth interface 55 on its top and a sixth interface 56 on its surface near the second interface 52. The fifth interface 55 and the sixth interface 56 are connected by an auxiliary pipeline 72.

[0029] In practical implementation, the compressible gas at the top of the medium storage tank 5 can directly act on the connection area of ​​the delivery pump 61 near the second interface 52 via the fifth interface 55, auxiliary pipeline 72, and sixth interface 56, quickly balancing the pressure fluctuations in this area. Simultaneously, it suppresses the generation of eddies in the first cooling medium at the interface, preventing gas from being drawn into the delivery pump 61 and further improving the stability of the medium delivery at the inlet of the delivery pump 61. Furthermore, the auxiliary pipeline 72 can transmit the static pressure at the top of the medium storage tank 5 to the sixth interface 56, maintaining the pressure in this area at a constant level equal to the sum of the compressible gas pressure at the top of the medium storage tank 5 and the static pressure of the liquid column in the auxiliary pipeline 72. Even if the delivery pump 61 has a strong suction effect, it can only reduce the pressure to this value and cannot continue to decrease it, preventing the liquid surface at the interface from sinking due to excessively low negative pressure, thus avoiding the formation of eddies.

[0030] The auxiliary pipeline 72 is provided with a transparent section 721. The highest position of the transparent section 721 is not lower than the highest liquid level in the medium storage tank 5, and the lowest position of the transparent section 721 is not higher than the lowest liquid level in the medium storage tank 5. When the cooling water device is running stably, the liquid level in the auxiliary pipeline 72 can be directly observed through the transparent section 721, thereby determining the liquid level height of the first cooling medium in the medium storage tank 5. When the cooling water device is running unstable, the medium flow status, whether air bubbles are entrained, and the liquid level fluctuation can be observed in real time through the transparent section 721, and the working status of the medium storage tank 5 can be monitored in a timely manner. In a specific embodiment, the transparent section 721 is at least partially vertically arranged. It should be noted that the highest liquid level in the medium storage tank 5 refers to the maximum liquid level height of the first cooling medium that can be stored in the medium storage tank 5; the lowest liquid level in the medium storage tank 5 refers to the minimum liquid level height of the first cooling medium that ensures normal suction by the delivery pump 61 and avoids liquid shortage and abnormal delivery in the pipeline.

[0031] The medium delivery pipeline further includes: a return port 81 connected to the heat exchange medium inlet 43 and an outlet 82 connected to the delivery pump 61; the return port 81 is used to return the first cooling medium after heat exchange in the external cooling device to the medium delivery pipeline, and the outlet 82 is used to transport the first cooling medium in the medium storage tank 5 to the outside, providing a medium output channel for the first cooling medium between the medium delivery pipeline and the external cooling device. The medium storage tank 5 is provided with a first interface 51 connected to the heat exchange medium outlet 44; a flow meter 91 is provided at the first interface 51 to monitor the flow rate of the first cooling medium flowing through the first interface 51 in real time and to provide real-time feedback on the circulation heat exchange status of the medium delivery pipeline.

[0032] A third interface 53 is provided on the lower side wall of the medium storage tank 5. A water inlet 83 and a three-way valve 63 are provided on the supplementary branch 71. The water inlet 83, the diaphragm pump 62, the second valve port 632 of the three-way valve 63, the first valve port 631 of the three-way valve 63, and the third interface 53 are sequentially connected to form the supplementary branch 71. A first switching valve 64 is provided at the water inlet 83 to control the opening and closing of the water inlet 83, thereby enabling the addition of the first cooling medium and the closure of the pipeline. The third valve port 633 of the three-way valve 63 is connected to the drain outlet 84 via a pipeline; a second switching valve 65 is provided at the drain outlet 84 to control the opening and closing of the drain outlet 84, thereby enabling the discharge of the medium from the medium storage tank 5 and the closure of the pipeline. The top of the medium storage tank 5 is provided with a fourth interface 54, which is connected to a vent 85 via a pipe. A third switching valve 66 is provided at the vent 85 to control the opening and closing of the vent 85, balance the air pressure inside and outside the medium storage tank 5, and simultaneously achieve tank sealing. When it is not necessary to replenish or discharge the first cooling medium in the medium storage tank 5, the first switching valve 64, the second switching valve 65, and the third switching valve 66 are in the closed state, making the replenishment branch 71 a closed pipeline, providing a sealed transmission environment for the pressure pulse generated by the diaphragm pump 62, and ensuring that the pressure pulse can be transmitted to the inside of the medium storage tank 5.

[0033] In a specific embodiment, the medium storage tank 5 is equipped with a thermometer 92, an electric heating element 93, and a liquid level switch 94. Combined with... Figure 8 As shown, the thermometer 92 and the heating element 93 are both immersed in the first cooling medium at the bottom of the medium storage tank 5. The thermometer 92 is used to monitor the real-time temperature of the first cooling medium; the heating element 93 is used to heat and control the temperature of the first cooling medium. If the temperature of the first cooling medium in the medium storage tank 5 is lower than the working threshold due to heat exchange inertia, or if the first cooling medium needs to be discharged, the heating element 93 can heat the first cooling medium to a suitable working temperature. The liquid level switch 94 is located in the medium storage tank 5 at the highest liquid level corresponding to the first cooling medium. It is used to detect whether the cooling medium has reached the highest liquid level. When the liquid level exceeds the limit, a signal is issued to prevent the first cooling medium from being overfilled and occupying the buffer space of the compressible gas in the upper part of the medium storage tank 5, which would affect the gas pressure stabilization and pressure compensation functions, and at the same time prevent the first cooling medium from overflowing from the top of the tank.

[0034] The cooling water device also includes a housing 10, which is used to install the internal circulation pipeline and the medium conveying pipeline, and at the same time protects the internal pipeline to prevent external collisions from damaging the pipeline. It realizes the integrated installation of various components, making the entire cooling water device more compact and rationally laid out, and facilitating overall transportation, installation and use. In a specific embodiment, the return port 81, outlet 82, injection port 83, drain port 84, and vent 85 are all located on the housing 10, facilitating the connection of these ports to external pipelines and equipment. This also allows for convenient arrangement of the interfaces, making it easier for operators to connect pipelines, perform maintenance, and conduct daily operations, thus improving the ease of use of the device. The transparent section 721 is installed on the housing 10, and an observation window is provided on the housing 10 directly opposite the transparent section 721. This allows operators to directly observe the liquid level changes, medium flow status, and whether air bubbles are trapped within the transparent section 721 without disassembling the housing 10, enabling real-time monitoring of the device's operating status, improving operational convenience, and reducing maintenance costs.

[0035] It should be noted that the cooling water device in this embodiment also includes a circuit section. The cooling water device in this embodiment mainly focuses on the specific design of the internal circulation pipeline and the medium delivery pipeline. As for the specific connection method of the circuit section, those skilled in the art can directly understand it based on common knowledge, and it will not be described in detail here.

[0036] The cooling water device provided in this embodiment achieves cooling of external equipment by using a combined heat exchange cooling system through an internal circulation pipeline and a medium delivery pipeline. This embodiment utilizes the compressible gas in the medium storage tank 5 and the diaphragm pump 62 to achieve pressure buffering and pulse pressure stabilization, eliminating the need for additional pressure stabilizing tanks, accumulators, or other dedicated pressure stabilizing components, thus simplifying the device's piping structure. The compressible gas buffers pipeline pressure fluctuations in real time, and the pressure pulses generated by the diaphragm pump 62 stabilize the pressure at the connection point of the delivery pump 61. Simultaneously, it replenishes the storage tank with the first cooling medium, effectively suppressing pipeline eddies and medium entrainment, and providing a medium replenishment function, ensuring stable operation and heat exchange efficiency of the delivery pump 61.

[0037] Example 2: This embodiment provides a data center for deploying data processing cabinets and providing a temperature-controlled operating environment. The data center includes the data processing cabinets and the cooling water system described in Embodiment 1. The data processing cabinets perform data processing operations; the cooling water system absorbs the heat generated by the data processing cabinets during operation.

[0038] In a specific embodiment, the return port 81 and outlet 82 of the cooling water device are respectively connected to the cooling pipes of the data processing cabinet, forming a closed-loop cooling cycle. In practice, the cooling water device continuously removes the heat generated by the operation of the data processing cabinet by circulating and delivering the first cooling medium, ensuring that the data processing equipment is in a stable operating temperature range.

[0039] The data center provided in this embodiment continuously absorbs the heat generated by the operation of the data processing cabinet through the cooling water device, providing a stable temperature-controlled environment for the data processing cabinet and ensuring its efficient and reliable operation.

[0040] The above-described embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
