Description

Technical Field

[0001] The present application relates to the technical field of liquid cooling equipment, and in particular to a liquid storage tank, a liquid cooling device and a containerized cooling system. Background Art

[0002] With the rapid development of digital technology, the demand for high-performance computing is growing. However, with existing computer hardware, high-performance computing also means high energy consumption, which in turn generates a lot of heat. Data center cooling is a key technology to ensure the continuous and stable operation of electronic equipment within the data center. Electronic equipment such as servers, storage devices, and network hardware generate significant heat during operation. If left uncontrolled, this heat can overheat, impact performance, and even damage the equipment. Therefore, effective cooling measures have a significant impact on the energy efficiency, reliability, and operating costs of data centers.

[0003] Traditional data center cooling systems rely primarily on air cooling, resulting in low energy efficiency. Immersive single-phase liquid cooling significantly improves cooling efficiency and reduces energy consumption. Immersive liquid cooling involves immersing servers in a chamber filled with an insulating coolant (such as transformer oil), which then removes heat through the flow of the coolant.

[0004] At present, after the coolant in the liquid cooling box absorbs the heat of the electronic equipment and is discharged, it can be sent to the liquid storage tank first and then to the heat dissipation module for heat dissipation and cooling before being transported to the liquid cooling box for circulation to cool the electronic equipment. The excess coolant is stored in the liquid storage tank to avoid the problem of unbalanced liquid flow inlet and outlet of the liquid cooling box.

[0005] However, currently the coolant in the tank is directly sucked into the heat dissipation module through the drain port on the tank wall. During this process, air may be drawn in to form bubbles, causing the coolant to emulsify and affecting the heat exchange efficiency. Utility Model Content

[0047] The following describes some embodiments of the present application in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0048] The embodiment of the present application discloses a container-type cooling system, which includes a container and a liquid cooling device located in the container. The liquid cooling device includes a heat dissipation module, a liquid cooling box and a liquid storage tank. The liquid storage tank has a liquid return port 11 and a liquid discharge port 12 running through the wall. The liquid return port 11 is mainly used to connect to the liquid outlet of the liquid cooling box, and the liquid discharge port 12 is used to connect to the inlet of the heat dissipation module. The outlet of the heat dissipation module is connected to the liquid inlet of the liquid cooling box. The heat dissipation module has a power pump to realize the circulation of the coolant through the power pump. The heat dissipation module is mainly used to dissipate heat and cool the coolant and then return it to the liquid cooling box to achieve continuous cooling of electronic equipment such as servers in the liquid cooling box. The liquid storage tank is used to temporarily store the coolant discharged from the liquid cooling box after absorbing heat, so as to avoid the problem of unbalanced liquid inlet and outlet flow of the liquid cooling box.

[0049] Please refer to Figure 1 and Figure 2The liquid storage tank includes a liquid storage tank body 10 and a liquid suction pipeline 20 in the liquid storage tank body 10. A liquid return port 11 and a liquid discharge port 12 are provided on the wall of the liquid storage tank body 10. The liquid suction pipeline 20 is distributed in the internal space of the liquid storage tank body 10 and is connected to the liquid discharge port 12. A plurality of liquid suction holes 23 are provided on the side of the liquid suction pipeline 20 facing the bottom wall of the liquid storage tank body 10.

[0050] In this way, after the coolant enters the internal space of the liquid storage tank 10 from the return liquid port 11, a liquid suction pipe 20 is set in the internal space of the liquid storage tank 10. Since a plurality of liquid suction holes 23 are set on the side of the liquid suction pipe 20 facing the bottom wall of the liquid storage tank 10, the position of the liquid suction holes 23 will basically be maintained below the liquid level of the coolant during the circulation of the coolant. The coolant is sucked to the discharge port 12 through the liquid suction holes 23, thereby avoiding the entrainment of air to form bubbles, thereby improving the emulsification of the coolant and ensuring the heat exchange efficiency.

[0051] Optionally, the liquid suction pipeline 20 includes a connecting pipe 21 and multiple liquid suction pipes 22 connected to the connecting pipe 21; one end of the connecting pipe 21 is connected to the drain port 12, and the other end of the connecting pipe 21 is closed; the end of the liquid suction pipe 22 away from the connecting pipe 21 is closed, and the side of the bottom wall of the liquid suction pipe 22 facing the liquid storage box 10 is provided with multiple liquid suction holes 23, so as to ensure that the coolant at various positions in the liquid storage box 10 is sucked into the connecting pipe 21 through each liquid suction pipe 22 and then discharged from the drain port 12, so as to better avoid being drawn into the space.

[0052] Specifically, the drain port 12 is located on one side of the liquid storage tank body 10 in the length direction, and the connecting pipe 21 extends along the length direction of the liquid storage tank body 10; each suction pipe 22 is arranged at intervals along the length direction of the liquid storage tank body 10, and the length direction of the suction pipe 22 forms an angle with the length direction of the liquid storage tank body 10, so that the suction pipe 22 is more evenly distributed to evenly suck the coolant from various places in the internal space of the liquid storage tank body 10.

[0053] Among them, the two opposite side walls of the liquid storage box 10 in its own width direction are respectively the first side wall 13 and the second side wall 14; the connecting pipe 21 is close to the first side wall 13 and away from the second side wall 14; all the suction pipes 22 are located on the side of the connecting pipe 21 close to the second side wall 14, so that each suction pipe 22 can be evenly distributed in the central area of the liquid storage box 10 to save the material and cost of the suction pipeline 20.

[0054] Of course, the connecting pipe 21 may also be located in the center of the liquid storage box 10, and the connecting pipe 21 may have multiple liquid suction tubes 22 on one side or both sides in the width direction of the liquid storage box 10. In other words, the connecting pipe 21 is located in the middle between the first side wall 13 and the second side wall 14, that is, the distance between the connecting pipe 21 and the first side wall 13 is equal to the distance between the connecting pipe 21 and the second side wall 14, and the connecting pipe 21 may have multiple liquid suction tubes 22 on at least one side in the width direction of the liquid storage box 10, that is, the connecting pipe 21 may have multiple liquid suction tubes 22 on the side close to the first side wall 13 and / or the side close to the second side wall 14.

[0055] Combine Figure 3 and Figure 4 In this embodiment, the liquid suction pipeline 20 further includes a support portion 24. The support portion 24 is provided between the connecting pipe 21 and the bottom wall of the liquid storage box 10, and / or between the liquid suction pipe 22 and the bottom wall of the liquid storage box 10. The support portion 24 thus supports the connecting pipe 21 and the liquid suction pipe 22, thereby improving the fixed stability of the liquid suction pipeline 20 within the liquid storage box 10.

[0056] Optionally, all the suction holes 23 on each suction tube 22 are divided into at least two rows parallel to each other along the circumference of the suction tube 22, and the suction holes 23 in two adjacent rows are staggered along the length direction of the suction tube 22, so that each suction tube 22 can suck coolant at a larger flow rate.

[0057] Of course, in some embodiments, the liquid suction pipeline 20 can also be a serpentine pipeline with multiple curved sections, and a plurality of liquid suction holes 23 are correspondingly provided on the bottom side.

[0058] In this embodiment, the liquid storage tank body 10 is located below the liquid cooling tank, and the liquid return port 11 is located at the top of the liquid storage tank body 10. In this way, the coolant in the liquid cooling tank may be drawn into the air to form bubbles due to the impact of the coolant in the liquid storage tank body 10 after falling from a high place into the liquid return port 11. In order to avoid this problem, the liquid storage tank further includes an elbow 30 located in the internal space of the liquid storage tank body 10. One end of the elbow 30 is connected to the liquid return port 11, and the other end of the elbow 30 is parallel to the bottom wall of the liquid storage tank body 10. The elbow 30 can also change the flow direction of the coolant, so that the coolant can be discharged from the other end of the elbow 30 and can escape to various places in the liquid storage tank body 10 in a direction parallel to the bottom wall of the liquid storage tank body 10.

[0059] In addition, in the present application, an exhaust port 15 is provided on the top of the liquid storage tank body 10, which is connected to an exhaust pipe through the exhaust port 15 to connect to the atmosphere, thereby ensuring that the air pressure in the liquid storage tank body 10 is balanced with the external environment, and the coolant can flow in and out of the liquid storage tank body 10 normally.

[0060] A liquid level display 40 is provided on the side wall of the liquid storage tank body 10. The liquid level display 40 can be a tubular element with scale lines, which is arranged vertically and the bottom end is connected to the internal space of the liquid cooling tank body. In this way, the liquid level display 40 is used to display the coolant level in the liquid storage tank body 10 in real time, which is convenient for users to read.

[0061] In addition, in this embodiment, combined with Figure 2 and Figure 5 A plurality of reinforcing ribs 50 are provided on the inner wall of the liquid storage box body 10, and the reinforcing ribs 50 are arranged at intervals along the length direction of the liquid storage box body 10, thereby improving the overall strength of the liquid storage box body 10 to ensure that the entire liquid storage box has better reliability and mechanical strength.

[0062] Specifically, the reinforcing rib 50 is in a ring shape extending along the circumference of the liquid storage box 10, so that the contact area between the reinforcing rib 50 and the liquid storage box 10 is large, and the reinforcing rib 50 itself as a continuous and uninterrupted ring component can provide greater mechanical strength.

[0063] The portion of the reinforcing rib 50 connected to the bottom wall of the liquid storage tank 10 is provided with multiple flow openings 51. For example, these flow openings 51 extend through the bottom edge of the reinforcing rib 50. This ensures that coolant on both sides of the width of the reinforcing rib 50 can communicate through these flow openings 51, thereby ensuring uniform coolant distribution and avoiding the formation of dead water areas. Furthermore, the portion of the reinforcing rib 50 connected to the top wall of the liquid storage tank 10 can also be provided with multiple flow openings 51. These flow openings 51 extend through the top edge of the reinforcing rib 50. This allows for convection exchange of coolant in the top edge of the liquid storage tank 10 even after the liquid storage tank 10 is fully filled, further avoiding the formation of dead water areas.

[0064] Of course, in some embodiments, the reinforcing rib 50 may also be provided on the first side wall 13 or the second side wall 14 , and may also be a multi-segment structure, as long as it can improve the strength.

[0065] In summary, the embodiments of the present application disclose a liquid storage tank, a liquid cooling device and a container-type cooling system. After the coolant enters the internal space of the liquid storage tank body 10 from the return liquid port 11, a liquid suction pipe 20 is set in the internal space of the liquid storage tank body 10. Since a plurality of liquid suction holes 23 are set on the side of the liquid suction pipe 20 facing the bottom wall of the liquid storage tank body 10, the position of the liquid suction hole 23 will basically be maintained below the liquid level of the coolant during the circulation of the coolant. The coolant is sucked to the discharge port 12 through the liquid suction hole 23, thereby avoiding the entrainment of air to form bubbles, thereby improving the emulsification of the coolant and ensuring the heat exchange efficiency.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
