[0002] With the popularization of electronic technology in modern production and life, more and more people have the need for data storage. However, due to limitations such as size, their electronic devices cannot store large amounts of data. As a result, big data storage based on network services has emerged. Big data can not only serve the purpose of data storage, but also help people complete certain tasks more quickly and accurately in daily production and life.

However, the mounting tank and the storage casing are connected by multiple sets of through holes, which not only poses a significant risk of leakage but also makes maintenance inconvenient. In view of this, this case was developed after in-depth research into the above problems. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 This utility model provides an implementation scheme: During the high-density operation of big data storage devices, their internal electronic components generate a large amount of heat. If the heat cannot be dissipated effectively and in a timely manner, it will cause the device temperature to rise sharply, leading to performance degradation, data errors, or even hardware damage. The current common heat dissipation solution is to set up an installation slot outside the storage device cabinet, install a heat exchanger inside the slot, and use circulating coolant to absorb the heat generated by the storage device. However, this solution usually requires multiple sets of through holes to be opened between the storage device casing and the external installation slot for connecting coolant pipelines. These through holes not only increase the complexity of the sealing interface and pose a high risk of coolant leakage, but also make the inspection, maintenance, or replacement of the entire cooling system very difficult due to the numerous pipeline connection points and dispersed structure, affecting the reliability and maintenance efficiency of data center operation.

[0021] To address the aforementioned issues, this application discloses a large data storage device, including a cooling tank 1, which is a rectangular cavity shell. A storage support 4 is disposed inside the cooling tank 1 for fixing the memory. The cooling tank 1 contains coolant that directly wraps around or submerges the storage support 4, providing a large-area direct contact cooling for the memory and efficiently absorbing the heat it generates. A heat exchange tank 2 is disposed on one side of the cooling tank 1, and a cooling heat exchange structure 3 is disposed inside the heat exchange tank 2. The heat exchange tank 2 serves as a container for secondary heat exchange, accommodating the cooling heat exchange structure 3 and guiding the flow of coolant to transfer the heat absorbed by the cooling tank 1 to an external cold source.

[0022] Cooling tank 1 and heat exchange tank 2 are connected by a sealed connection controller 5. The sealed connection controller 5 is the key fluid channel and drive unit connecting cooling tank 1 and heat exchange tank 2. It integrates the two into a closed loop system, replacing multiple external connection points and through holes that are scattered in the traditional solution, greatly reducing potential leakage points, and centralizing the fluid drive function.

[0023] According to the instruction manual Figure 1-3As can be seen, the aforementioned sealed connection controller 5 includes a connecting hole, which is the necessary channel for fluid exchange between the cooling tank 1 and the heat exchange tank 2, ensuring that the coolant can flow directionally between the two chambers. A connecting hole is provided at the bottom of the heat exchange tank 2, and a connecting seat 51 extends from the connecting hole. The connecting seat 51 serves as a rigid extension interface of the connecting hole, providing a stable installation base. A conveying pipe 53 is connected to one side of the connecting seat 51 via a flange joint 52. The flange joint 52 provides a quick-disassembly sealed connection method, facilitating the maintenance and replacement of the conveying pipe 53 or the entire sealed connection controller 5, while ensuring reliable sealing at the connection point, significantly reducing the risk of leakage at this critical interface. A control motor 54 is installed on one side of the conveying pipe 53. The control motor 54 provides the power source to drive the coolant circulation. The drive end of the control motor 54 is connected to the drive shaft 55. The drive impeller 56 is connected to the outside of the drive shaft 55. The drive impeller 56 is the core of the pump. The rotation of the drive impeller 56 generates centrifugal force or thrust, which directly pushes the coolant from the heat exchange tank 2 through the conveying pipe 53 to the cooling tank 1, forming a forced circulation power source. A water exchange seat 57 is provided at the head end of the conveying pipe 53. The water exchange seat 57 is the transition interface between the conveying pipe 53 and the cavity of the cooling tank 1, ensuring that the coolant enters the cooling tank 1 smoothly and with low resistance. The water exchange seat 57 is connected to the inside of the cooling tank 1.

[0024] The top of the cooling tank 1 is equipped with an overflow channel 6. The overflow channel 6 has an inverted U-shaped structure and its two ends are connected to the cooling tank 1 and the heat exchange tank 2 respectively. The overflow channel 6 uses the inverted U-shaped siphon principle. When the liquid level in the cooling tank 1 rises above the set height due to thermal expansion or flow fluctuation, the excess coolant can automatically overflow back to the heat exchange tank 2, maintaining the pressure balance and liquid level stability in the system and preventing the cooling tank 1 from being too full. This is an important guarantee for the safe operation of the system.

[0025] As a preferred option, a support frame 7 is welded to the side wall of the cooling tank 1. The support frame 7 provides a sturdy mounting platform for the heat exchange tank 2 and the sealing connection controller 5, ensuring that the heat exchange tank 2 is accurately and stably positioned, and enhancing the rigidity and stability of the overall structure. This assembly relationship makes the heat exchange tank 2 a relatively independent module, which is convenient for overall disassembly and maintenance.

[0026] As a preferred option, the conveying pipe 53 is a hollow shell with a circular cross-section. The circular cross-section design increases the effective cross-sectional area of ​​the fluid channel and reduces the flow resistance. At the same time, the structure is compact and easy to arrange in a limited space. Its hollow shell constitutes the core conveying pipe for the coolant to flow from the heat exchange tank 2 to the cooling tank 1. The flange joint 52 is integrally connected with the conveying pipe 53.

[0027] As a preferred option, the end of the conveying pipe 53 is provided with a sealed bearing 58. The sealed bearing 58 provides a double sealing function while supporting the rotation of the drive shaft 55, preventing the coolant in the conveying pipe 53 from leaking outward along the drive shaft 55 and preventing external impurities from entering the system. The control motor 54 is connected to the drive shaft 55 through a gear box, enabling the motor to operate in the high-efficiency speed range, while matching the speed and torque required by the drive impeller 56, thus optimizing the system energy efficiency.

[0028] As a preferred option, the outer diameter of the drive impeller 56 is matched with the inner diameter of the delivery pipe 53. This close matching design can minimize fluid leakage between the drive impeller 56 and the pipe wall, improve pumping efficiency, and ensure that the coolant flow meets the heat dissipation requirements.

[0029] As a preferred option, the cooling heat exchange structure 3 further includes a plate cooler 31, which is the main heat exchange element. It has a complex flow channel inside for the external cold source to flow, and has a very large specific surface area. Part of the plate cooler 31 is immersed in the heat exchange tank 2. The immersion design allows the large heat exchange surface of the plate cooler 31 to directly contact the coolant in the heat exchange tank 2. Efficient heat conduction is carried out through the metal plate wall, and the heat carried by the coolant is quickly transferred to the cold source fluid flowing through the plate cooler 31.

[0030] Working process: The control motor 54 starts, driving the drive shaft 55 and drive impeller 56 to rotate at high speed through the gearbox. The suction force generated by the drive impeller 56 draws the coolant in the heat exchange tank 2 into the delivery pipe 53 through the connecting hole and connecting seat 51. After being pressurized, it is pumped into the cooling tank 1 through the water exchange seat 57. The coolant in the cooling tank 1 absorbs the heat generated by the storage container on the storage bracket 4 and its temperature rises. The high-temperature coolant circulates in the tank. Its liquid level may rise due to thermal expansion or flow rate. When it exceeds the inlet height of the overflow channel 6, the excess liquid... The coolant automatically flows back to the heat exchange tank 2 through the inverted U-shaped overflow channel 6, maintaining the balance of liquid level and pressure. The high-temperature coolant flowing back to the heat exchange tank 2 exchanges heat with the plate cooler 31 immersed in it. The heat is transferred to the external cold source fluid that flows through the plate cooler 31 and is introduced by the inlet pipe 32. The cooled coolant accumulates at the bottom of the heat exchange tank 2, waiting to be pumped back into the cooling tank 1 by the sealed connection controller 5 to form a closed loop. The heated cold source fluid is discharged to the external cooling system through the outlet pipe 33 for heat dissipation and cooling, completing the entire heat dissipation cycle.

[0031] In summary, this big data storage device, by integrating the cooling tank 1, heat exchange tank 2, and the sealed connection controller 5 with integrated pumping function into a single design, and utilizing the overflow channel 6 to achieve pressure self-balancing, completely eliminates the need for multiple through holes and distributed pipeline connections between the cabinet and the mounting slot in traditional solutions. This significantly reduces the risk of leakage, improves maintenance convenience, and optimizes heat dissipation and reliability.
