[0007] By using the above-mentioned device, by immersing the target object in the cooling liquid in the immersion cavity, the cooling liquid directly contacts the target object to rapidly absorb and conduct heat. Due to the flow property of the cooling liquid, the heat can be uniformly distributed in the entire immersion cavity, avoiding the problem of local overheating, ensuring the temperature uniformity of the target object in each part, which is particularly important for high-performance computing devices, and can reduce the performance degradation or device damage caused by uneven temperature. Moreover, the water cooling unit is used to condense the steam, transfer the heat of the target object to the cooling liquid, and then return to the liquid cooling tank through the return pipe, which has lower energy consumption.

[0010] Preferably, the liquid cooling box is provided with a sealing cover at the top, the sealing cover is provided with an auxiliary air cooling assembly, the auxiliary air cooling assembly includes a plurality of fans, and the plurality of fans are fixed on the sealing cover through a mounting plate.
[0011] By adopting the above device, when in use, the fan is turned on to transfer cool air to the surface of the cooling liquid, and the air blown by the fan can disturb the cooling liquid, further cooling the cooling liquid, thereby indirectly cooling the target object.
[0012] Preferably, the sealing cover is connected with the liquid cooling box through a connecting piece, and the sealing cover rotates around the liquid cooling box under the action of the connecting piece to open and close.
[0013] By adopting the above device, by setting the sealing cover, the entry of external dust, pollutants and the like into the liquid cooling box is reduced, and the internal target object is protected from damage. In addition, the sealing cover can be opened by rotation, facilitating maintenance, cleaning or replacement of the cooling liquid and the like, and the convenience of maintenance is improved.
[0014] Preferably, the liquid cooling box is provided with a containing cavity at the upper portion, the containing cavity is provided with a condenser, and the position of the condenser corresponds to the liquid outlet.
[0015] By adopting the above device, the high-temperature steam is reduced to liquid phase by the condenser, the condenser ensures the continuous circulation of the cooling liquid, and through the condensation process, the liquid cooling liquid is refluxed to the liquid cooling box to continue to absorb the heat of the target object, and the circulation operation of the entire thermal management system is maintained.

Under normal circumstances, the pressure inside the liquid cooling box is lower than the elastic force of the elastic element. Under the action of the elastic force of the elastic element, the sealing plug is tightly pressed against the side wall of the exhaust valve. When the pressure inside the liquid cooling box gradually increases to exceed the elastic force of the elastic element, the sealing plug is pushed open, and the gas inside the liquid cooling box is discharged from the gap between the sealing plug and the side wall of the exhaust valve, thereby reducing the gas pressure inside the bottle.

[0022] This application has the following beneficial effects:
[0023] 1. In this application, by immersing the target object in the coolant within the immersion chamber, the coolant directly contacts the target object and rapidly absorbs and conducts heat.

This is particularly important for high-performance computing devices, reducing performance degradation or equipment damage caused by uneven temperature. Furthermore, this application utilizes a water-cooled unit to condense steam, transferring the heat from the target object to the coolant, which is then returned to the liquid cooling tank via a return pipe, resulting in lower energy consumption.

[0030] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.
[0031] An immersion heat manager, such as Figures 1-3 As shown, the system includes a liquid cooling tank 1, a water-cooled unit 2, and a transmission pipeline 3. The liquid cooling tank 1 contains an immersion chamber 11 for placing the target object. The immersion chamber 11 is filled with coolant, and the target object is sealed and immersed in the coolant for rapid cooling. The water-cooled unit 2 is connected to one side of the liquid cooling tank 1, and a transmission pipeline 3 connects the liquid cooling tank 1 and the water-cooled unit 2, forming a circulation of coolant between the liquid cooling tank 1, the transmission pipeline 3, and the water-cooled unit 2. The transmission pipeline 3 includes a steam pipe 31 and a return pipe 32. The water-cooled unit 2 reduces the steam in the steam pipe 31 back to the coolant, which then flows back to the liquid cooling tank 1 through the return pipe 32 to reabsorb and conduct heat.
[0032] like Figures 1-3 As shown, the liquid cooling tank 1 has an outlet 12 and an inlet 13 on one side, and the water-cooled unit 2 has an inlet 21 and an outlet 22 on the opposite side of the liquid cooling tank 1. A steam pipe 31 connects the outlet 12 and the inlet 21, and a return pipe 32 connects the inlet 13 and the outlet 22. During operation, the coolant in the immersion chamber 11 absorbs heat and reaches its boiling point, changing from a liquid phase to a gas phase. At this time, the gaseous coolant passes through the outlet 12, the steam pipe 31, and the inlet 21 to reach the water-cooled unit 2. The water-cooled unit 2 restores the gaseous coolant to a liquid phase, allowing it to flow back into the immersion chamber 11 to reabsorb heat from the target object, thus realizing the circulation of the coolant and forming an effective heat exchange cycle. This circulation process greatly improves the heat transfer efficiency.
[0033] like Figures 1-3As shown, the upper part of the liquid cooling box 1 is provided with a containing cavity 15, and the condenser 5 is arranged in the containing cavity 15. The position of the condenser 5 corresponds to the liquid outlet 22, so that the cooling liquid can be rapidly cooled during the backflow process. The condenser 5 adopts a copper pipe fin structure, the cooling liquid flows in the copper pipe, and the fins increase the heat exchange area and improve the heat exchange efficiency. The inlet and outlet of the condenser 5 are provided with filter screens to reduce impurities entering the transmission pipeline 3 and affecting the cooling effect.
[0034] As shown in the figure, Figures 1-3 The top of the liquid cooling box 1 is provided with a sealing cover 14, and the bottom of the sealing cover 14 is provided with an auxiliary air cooling assembly 4. The auxiliary air cooling assembly 4 includes a plurality of fans 41, four in this embodiment, and the plurality of fans 41 are fixed to the sealing cover 14 by a mounting plate 42. In use, the fans 41 are turned on to transfer cool air to the surface of the cooling liquid, and the air blown by the fans 41 can disturb the cooling liquid, further cooling the cooling liquid, thereby indirectly cooling the target object.
[0035] In addition, as shown in the figure, Figures 1-3 The sealing cover 14 is connected with the liquid cooling box 1 through a connecting piece 141, and the sealing cover 14 is rotated to open and close around the liquid cooling box 1 under the action of the connecting piece 141. In this embodiment, the connecting piece 141 adopts a hinge structure. The edge of the sealing cover 14 is provided with a rubber sealing strip to ensure the sealing property of the liquid cooling box 1 when the sealing cover 14 is closed, reducing the entry of external dust, pollutants and the like into the inside of the liquid cooling box 1, and protecting the target object inside from being damaged.
[0036] As shown in the figure, Figures 1-3 The inside wall of the liquid cooling box 1 is provided with a temperature sensor 6, the temperature sensor 6 is immersed in the cooling liquid, a water pump 7 is arranged on the backflow pipe 32, and the temperature sensor 6 is signal connected with the water pump 7. In this embodiment, the temperature sensor 6 adopts a waterproof design and can still work normally after being soaked in the cooling liquid for a long time. The water pump 7 is driven by a brushless DC motor. When the temperature sensor 6 detects that the temperature in the liquid cooling box 1 exceeds a preset value, the water pump 7 starts to increase the circulation speed of the cooling liquid and accelerate heat dissipation, thereby realizing more effective heat management.
[0037] As shown in the figure, Figures 1-3 The sealing cover 14 is provided with a pressure relief valve 16, the pressure relief valve 16 includes a sealing plug 161, an elastic member 162 and a valve cover 163. The valve cover 163 is provided with a vent hole 163a, the cross-sectional shape of the sealing plug 161 is star-shaped, there is a gap between the star-shaped sealing plug 161 and the side wall of the valve body of the pressure relief valve 16, the elastic member 162 is located between the sealing plug 161 and the valve cover 163, and the valve cover 163 is threadedly connected to the outside of the pressure relief valve 16. When the pressure in the liquid cooling box 1 exceeds a safe range, the elastic member 162 is compressed, the sealing plug 161 is opened, and the gas is discharged through the vent hole 163a to release the pressure. In this embodiment, the elastic member 162 is selected as a spring.
[0038] As Figure 2 shown, the bottom of the immersion cavity 11 is provided with two parallel support bars 17 for supporting the target object. In use, the target object is placed on the support bars 17 so that the bottom of the target object can also contact the cooling liquid, further improving the cooling effect of the target object. In addition, a plurality of through holes 171 are formed in the support bars 17 for the circulation of cooling liquid, greatly improving the heat dissipation effect of the target object.
[0039] Working principle: Through the combination of the liquid cooling tank 1, the water cooling unit 2 and the transmission pipeline 3, efficient and stable heat management is achieved. The cooling liquid in the liquid cooling tank 1 can quickly take away the heat of the target object, and the cooling liquid absorbs heat to reach the boiling point and changes from liquid to gas. At this time, the gaseous cooling liquid passes through the gas outlet 12, the steam pipe 31 and the gas inlet 21 to reach the water cooling unit 2, and the water cooling unit 2 reduces the gaseous cooling liquid to liquid phase, so that it flows into the immersion cavity 11 again, realizing the circulation of the cooling liquid. The auxiliary air cooling assembly 4 further enhances the heat dissipation effect, ensuring that good heat dissipation performance can be maintained under high load conditions. The sealing cover ensures the sealing of the device. The linkage control of the temperature sensor 6 and the water pump 7 realizes intelligent adjustment, ensuring that the cooling effect is always in the best state. The pressure relief valve 16 ensures the safety of the device, avoiding safety hazards caused by excessive pressure.
