Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology for electronic devices, specifically an integrated structure for an immersion liquid cooling heat dissipation module. Background Technology

[0002] As electronic devices develop towards higher power and miniaturization, the heat generated per unit volume increases dramatically. Traditional air cooling methods are no longer sufficient to meet the heat dissipation requirements. Immersion liquid cooling has become one of the mainstream directions for heat dissipation of high-power electronic devices due to its advantages such as high heat dissipation efficiency, low noise, and low energy consumption.

[0003] Immersion liquid cooling technology, with its high thermal conductivity, offers 3-5 times the heat dissipation efficiency of air cooling, making it a core solution for high-power equipment cooling. However, existing immersion liquid cooling structures have two major drawbacks: First, the cooling systems are mostly designed as "single air cooling" or "single water cooling," failing to achieve tiered heat dissipation. This results in incomplete cooling of the coolant, leading to slower cooling of electronic equipment within the immersion tank and affecting its operational stability. Second, components such as pumping, cooling, and recirculation are installed separately, requiring dedicated installation space. This results in poor adaptability and a complex assembly process, failing to meet the layout requirements of high-density data centers for "space saving and modular integration."

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides an integrated structure for an immersion liquid cooling heat dissipation module, which has the following beneficial effects:

[0016] 1. This utility model, by setting a liquid extraction component, a primary cooling component, and a secondary cooling component on one side of the mounting plate, allows for tiered circulation cooling of the coolant within the immersion tank. The primary cooling component features an S-shaped water flow channel within its air-cooled chamber, extending the air-cooling time of the coolant.

Detailed Implementation

[0024] 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.

[0025] Example

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, an embodiment of this utility model proposes an integrated structure for an immersion liquid cooling heat dissipation module, including an immersion tank 1, a mounting plate 2 fixedly connected to one side of the immersion tank 1, and a liquid extraction assembly, a primary cooling assembly 6, and a secondary cooling assembly 7 respectively disposed on the mounting plate 2 from top to bottom. The liquid extraction assembly includes a first water pump 4 fixedly connected to one side of the mounting plate 2, and a liquid extraction pipe 3 and a liquid discharge pipe 5 respectively connected to the first water pump 4. The liquid extraction end of the liquid extraction pipe 3 extends to the upper inner side of the immersion tank 1. The primary cooling assembly 6 includes an air-cooled box 601 and... The heat exchange plate 606 and the air-cooled box 601 are fixedly connected to one side of the mounting plate 2. Multiple heat exchange plates 606 are integrally formed on the air-cooled box 601. S-shaped water flow channels 607 are formed between the multiple heat exchange plates 606. The S-shaped design of the water flow channels 607 extends the air-cooling time of the coolant, thereby increasing the cooling effect. The water flow channels 607 penetrate the top and bottom of the air-cooled box 601, and the drain port of the drain pipe 5 is connected to the top of the water flow channels 607. The secondary cooling assembly 7 includes a water distribution plate 701, a water-cooled box 703, and a water collection tank 7. 05. A fixing bracket 709 is fixedly connected between the water distribution plate 701, the water cooling box 703, and the water collection box 705 and the mounting plate 2. A guide pipe connects the drain port at the bottom of the water flow channel 607 and the inlet port at the top of the water distribution plate 701, thereby draining the initially cooled coolant into the water distribution plate 701. The lower surface of the water distribution plate 701 is connected to an array of distributed branch pipes 702, which evenly guide the coolant into each branch pipe 702, increasing the contact area with the cold water and facilitating effective and uniform cooling of the coolant. The branch pipes 702 penetrate the water cooling box. The tank 703 is connected to the water collection tank 705 through the drain outlet 704 at the lower end. The water collection tank 705 collects the coolant for centralized return. The secondary cooling component 7 also includes a second water pump 708 fixedly connected to one side of the mounting plate 2. A water collection pipe 706 is connected between the outlet of the water collection tank 705 and the second water pump 708, and a water delivery pipe 707 is connected between the outlet of the second water pump 708 and the immersion tank 1. The cooled coolant is reintroduced into the inner bottom of the immersion tank 1 through the water delivery pipe 707 to achieve coolant circulation cooling.

[0027] It should be noted that the coolant in the immersion tank 1 directly contacts electronic equipment (such as server chips), and its temperature rises after absorbing the heat generated by the equipment's operation. The first water pump 4 of the pumping assembly provides power to accurately extract the high-temperature coolant through the pumping pipe 3 extending to the upper inner side of the immersion tank 1 (the high-temperature coolant floats to the top due to its lower density). The high-temperature coolant is then transported to the primary cooling assembly 6 through the drain pipe 5, completing the transfer of heat from the tank to the cooling system. The staged cooling logic is as follows: the high-temperature coolant first enters the primary cooling assembly 6 for preliminary air cooling, and then flows into the secondary cooling assembly 7 for deep water cooling. Through the stepped design of "pre-cooling with air cooling followed by fine water cooling", the coolant temperature is ensured to drop to the target range. Low-temperature reflux and circulation: the low-temperature coolant after secondary cooling is transported to the bottom inner side of the immersion tank 1 through the second water pump 708 and the water delivery pipe 707 (the low-temperature coolant has a high density and can form a natural convection of "cooling from the bottom and heating from the top") to reabsorb the heat from the electronic equipment, forming a continuous heat dissipation cycle and maintaining a stable temperature inside the tank.

[0028] like Figure 5 As shown, in some embodiments, a water-cooled inlet pipe is connected to one side of the water-cooled box 703, and a water-cooled outlet pipe is connected to the other side of the water-cooled box 703.

[0029] It should be noted that external low-temperature cooling water enters the interior of the water-cooled box 703 through the water-cooled inlet pipe, filling the gap between the water-cooled box 703 and the branch pipe 702, forming a "cold water environment" surrounding the branch pipe 702; heat exchange process: the coolant flowing in the branch pipe 702 is the coolant after primary cooling. Because the pipe wall is made of a heat-conducting material (such as copper or stainless steel), heat will be transferred from the coolant in the pipe to the external low-temperature cooling water, realizing secondary cooling of the coolant; waste heat discharge: the temperature of the cooling water increases after absorbing heat, and then it is discharged from the water-cooled box 703 through the water-cooled outlet pipe, ensuring that the water-cooled box 703 always maintains a low-temperature environment and ensuring the continuous and efficient secondary cooling.

[0030] like Figure 2 As shown, in some embodiments, the top and bottom of the air-cooled box 601 are fixedly connected to a mounting base 602, and the mounting base 602 is fixedly connected to the mounting plate 2 by bolts.

[0031] It should be noted that the mounting base 602 is fixedly connected to the mounting plate 2 by bolts, which makes the installation stable and removable, convenient and quick.

[0032] like Figure 2 , Figure 3 and Figure 4As shown, in some embodiments, a cooling channel 605 is provided in the heat exchange plate 606, the cooling channel 605 runs through both sides of the cooling box 601, and an outer frame 603 is fixedly connected to one side of the cooling box 601 corresponding to the cooling channel 605, and a fan 604 is installed on the outer frame 603.

[0033] It should be noted that when the fan 604 is running, it generates forced airflow, which is guided through the outer frame 603 to the inlet of the air-cooling channel 605. The airflow passes through both sides of the air-cooling box 601 along the air-cooling channel 605, forming a directional airflow of "air entering from one side of the fan 604 and exiting from the other side". The air-cooling channel 605 is opened inside the heat exchange plate 606, which in turn surrounds the S-shaped water flow channel 607, forming a three-layer structure of "water flow channel 607, heat exchange plate 606, and air-cooling channel 605". The high-temperature coolant in the water flow channel 607 transfers heat to the heat exchange plate 606, and then the forced airflow in the air-cooling channel 605 quickly removes the heat, achieving the initial cooling of the coolant.

[0034] like Figure 1 As shown, in some embodiments, heat dissipation fins 8 are fixedly connected to both sides of the immersion tank 1, and multiple heat dissipation fins 8 are provided and are equidistantly arranged on the immersion tank 1.

[0035] It should be noted that the heat dissipation fins 8 are designed to assist in the heat dissipation of the immersion tank 1 and to help cool the coolant inside the immersion tank 1.

[0036] like Figure 2 and Figure 5 As shown, in some embodiments, a sealing ring is provided at the connection between the branch pipe 702 and the water-cooled box 703; a sealing gasket is provided at the connection between the air-cooled box 601 and the outer frame 603.

[0037] It should be noted that a sealing ring is provided at the connection between the branch pipe 702 and the water-cooled box 703 to prevent cold water leakage; a sealing gasket is provided at the connection between the air-cooled box 601 and the outer frame 603. The sealing gasket is a rubber gasket, which can ensure stability, absorb the vibration generated by the fan 604 during operation, reduce the vibration of the device, and prevent air leakage, thereby ensuring the cooling effect.

[0038] The working principle and usage steps of this utility model are as follows: After the coolant in the immersion tank 1 directly contacts the electronic equipment and absorbs heat, it rises to the upper part of the tank due to the decrease in density; the first water pump 4 drives the liquid extraction pipe 3 to extract the high-temperature coolant, which is then transported to the first-stage cooling component 6 through the liquid discharge pipe 5, completing the transfer of heat from the tank to the cooling system; First-stage air-cooling pre-cooling: The high-temperature coolant enters the S-shaped water flow channel 607 of the first-stage cooling component 6. The S-shaped design extends the residence time of the coolant. The fan 604 generates forced airflow, which is guided by the outer frame 603 into the air-cooling channel 605 inside the heat exchange plate 606. The airflow and the coolant in the water flow channel 607 exchange heat efficiently through the heat exchange plate 606, achieving initial cooling of the coolant; Second-stage water-cooling fine cooling: The initially cooled coolant flows into the second-stage cooling component 7 through the guide pipe. The water distribution plate 701 evenly distributes the coolant to the array of branch pipes 702. The branch pipes 702 pass through the water-cooled tank 703. External cooling water enters the water-cooled tank 703 through the water-cooled inlet pipe and exchanges heat with the coolant in the branch pipes 702 for a second time, completing deep cooling. The cooled water after absorbing heat is discharged from the water-cooled outlet pipe. The cooled coolant flows into the water collection tank 705 through the drain connector 704. Low-temperature reflux circulation: The low-temperature coolant in the water collection tank 705 enters the second water pump 708 through the water collection pipe 706. The second water pump 708 delivers it to the bottom of the immersion tank 1 through the water delivery pipe 707. The low-temperature coolant diffuses from the bottom and forms a "cooler at the bottom and hotter at the top" directional convection with the high-temperature area inside the tank, reabsorbing the heat of the electronic equipment and forming a continuous heat dissipation cycle.

[0039] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
