[0052] The following is an explanation of the implementation of the present application by means of specific embodiments. People familiar with the technology can easily understand other advantages and effects of the present application from the contents disclosed in this specification.

[0053] It should be noted that, in the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be described in detail below with reference to the drawings and in combination with the embodiments. In order to enable those skilled in the art to better understand the present application scheme, the technical scheme in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only embodiments of a part of the present application, not all embodiments. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in the field without making creative work should fall within the scope of protection of the present application.

[0054] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0055] An embodiment of the present application provides an immersion liquid cooling cabinet, including an inner tank assembly, a chassis and a radiator. The inner tank assembly includes a liquid inlet and a liquid outlet, and accommodates an electronic device including a chassis, and the chassis includes an immersion chamber accommodating a heating element. The radiator is arranged in the chassis, and the radiator includes an inlet and an outlet, the inlet is located above the outlet, the inlet is connected to the liquid inlet and the immersion chamber, and the outlet is connected to the liquid outlet and the immersion chamber. The coolant flows from the inlet to the bottom of the inner tank assembly, and the liquid level of the coolant in the inner tank assembly gradually rises. When the liquid level of the coolant in the inner tank assembly rises to the inlet, the coolant flows from the inlet to the bottom of the immersion chamber, and the coolant absorbs the heat generated by the electronic device. When the liquid level of the coolant in the immersion chamber rises to the outlet after absorbing heat, the coolant flows out from the outlet after absorbing heat, and flows out from the inner tank assembly through the outlet.

[0056] In the embodiments of the present application, the heat generating components in the electronic device are cooled by the mechanism that the heat sink and the coolant enhance the fluidity under the action of gravity, thereby enhancing the heat dissipation performance and improving the heat dissipation uniformity of the electronic device.

[0057] In order to more clearly understand the structure and working principle of the immersion liquid cooling cabinet provided in the embodiments of the present application, a detailed description will be given below in conjunction with the accompanying drawings.

[0058] See also Figure 1 , which is a schematic diagram of an immersion liquid cooling cabinet according to an embodiment of the present application. Figure 1 As shown, the immersion liquid cooling cabinet 1 includes an outer frame assembly 10, an inner tank assembly 20, a chassis 30, and a bracket assembly 40 (see Figure 4 ), a coolant pipe assembly 60 and a hoop 70. The liner assembly 20 includes a connector seat 50.

[0059] See also Figure 2 , which is a schematic diagram of an outer frame assembly according to an embodiment of the present application. Figure 1 and Figure 2 As shown, the outer frame assembly 10 has a receiving space, and the receiving space receives the inner tank assembly 20, the chassis 30 and the bracket assembly 40 (see Figure 4). The outer frame assembly 10 includes an input port 11 and an output port 12. The input port 11 is disposed on the side wall of the outer frame assembly 10, and guides the cooling fluid into the inner tank assembly 20. The cooling fluid absorbs the heat of the heating element in the chassis 30 to cool the heating element. The output port 12 is disposed on the side wall of the outer frame assembly 10 and is located at the bottom of the outer frame assembly 10; in other words, the input port 11 is located above the output port 12. The output port 12 guides the cooling fluid after absorbing heat to flow out of the outer frame assembly 10. For example, the number of the input ports 11 is two, and the number of the output ports 12 is two. The two input ports 11 are respectively disposed on the left and right panels of the outer frame assembly 10, and the two output ports 12 are respectively disposed on the left and right panels of the outer frame assembly 10, and the two input ports 11 are respectively located above the corresponding two output ports 12.

[0060] See also Figure 3 , which is a schematic diagram of an inner container assembly according to an embodiment of the present application. Figure 2 and Figure 3 As shown, the inner liner assembly 20 is disposed in the outer frame assembly 10 and is detachably connected to the outer frame assembly 10. For example, the side wall of the inner liner assembly 20 has a plurality of hooks, and the inner side of the outer frame assembly 10 is provided with a plurality of engaging holes corresponding to the plurality of hooks. The inner liner assembly 20 is connected to the outer frame assembly 10 through the engagement of the plurality of hooks with the plurality of engaging holes, and the bottom of the inner liner assembly 20 abuts against the bottom of the outer frame assembly 10. The inner liner assembly 20 includes a liquid inlet 21 and a liquid outlet 22, and the liquid inlet 21 and the liquid outlet 22 are both located at the bottom of the inner liner assembly 20. The liquid inlet 21 is disposed on the side wall of the inner liner assembly 20 and is connected to the input port 11; the liquid outlet 22 is disposed on the side wall of the inner liner assembly 20 and is connected to the output port 12, and the side wall of the inner liner assembly 20 where the liquid inlet 21 is located is different from the side wall of the inner liner assembly 20 where the liquid outlet 22 is located. For example, the structure of the inner liner assembly 20 is a rectangular parallelepiped, the number of liquid inlets 21 is two, the number of liquid outlets 22 is two, the two liquid inlets 21 are arranged on the front side wall and the rear side wall of the inner liner assembly 20, and the two liquid outlets 22 are arranged on the left side wall and the right side wall of the inner liner assembly 20 and are connected to the corresponding two output ports 12.

[0061] The chassis 30 is used to accommodate the heating element and is arranged in the inner tank assembly 20. The chassis 30 includes an immersion cavity in which the heating element is accommodated. Specifically, the chassis 30 is inserted into the inner tank assembly 20 and is located in the inner tank assembly 20. The chassis 30 is a hollow shell with an immersion cavity in the chassis 30. The immersion cavity accommodates the circuit board and is a space for the cooling fluid to flow in the chassis 30. The heating element is arranged on the circuit board and is an electronic element that generates high temperature and high heat during operation. The heating element is a processor (CPU), a graphics processing unit (GPU) or other communication elements that generate high temperature and high heat.

[0062] The cooling liquid pipeline assembly 60 is disposed in the inner liner assembly 20 and is detachably connected to the liquid inlet 21. Specifically, the cooling liquid pipeline assembly 60 surrounds the inner liner assembly 20, and abuts against the inner liner assembly 20 through a clamp, and connects the liquid inlet 21 and the input port 11 through two joints. The cooling liquid pipeline assembly 60 includes a liquid inlet cavity 61, an input pipeline 62, and a first joint 63. The liquid inlet cavity 61 is disposed on the side wall of the inner liner assembly 20, the first joint 63 is disposed at the upper part of the liquid inlet cavity 61 and connected to the input port 11, and the liquid inlet cavity 61 receives the cooling fluid through the first joint 63; the input pipeline 62 is connected to the liquid inlet cavity 61, and is connected to the liquid inlet 21 through the second joint. The cooling fluid flows from the input port 11 into the first joint 63 and flows through the liquid inlet cavity 61, and then the cooling fluid flows from the liquid inlet cavity 61 into the input pipeline 62, and flows into the liquid inlet 21 through the input pipeline 62. For example, the number of liquid inlet cavities 61 is two, the number of input pipes 62 is two, the two liquid inlet cavities 61 are arranged on the left and right walls of the inner liner assembly 20 and are connected to the two input ports 11, and the two input pipes 62 are arranged on the front and rear side walls of the inner liner assembly 20 and are connected to the two liquid inlets 21.

[0063] For example, there are two hoops 70, and the two hoops 70 are spaced apart and parallel to each other. One of the two hoops 70 surrounds the liner assembly 20 and abuts against the two liquid inlet chambers 61; for example, the hoop 70 abuts against the upper part of the two liquid inlet chambers 61. The other hoop 70 surrounds the liner assembly 20. The two hoops 70 increase the structural strength of the liner assembly 20 by surrounding the liner assembly 20, that is, the two hoops 70 can act as reinforcing ribs. The number of hoops 70 can be adjusted according to the configuration of the liner assembly 20, and the number of hoops 70 is not limited here.

[0064] See also Figure 4 , which is a schematic diagram of a bracket assembly according to an embodiment of the present application. Figure 3 and Figure 4 As shown, the bracket assembly 40 is disposed in the inner liner assembly 20 and is an independent assembly, and is detachably connected to the inner liner assembly 20; specifically, the bracket assembly 40 is fixed to the inner side of the inner liner assembly 20 through a plurality of screws, and abuts against the inner wall of the inner liner assembly 20.

[0065] The chassis 30 is disposed in the bracket assembly 40 and is detachably connected to the bracket assembly 40; in other words, the chassis 30 is disposed in the inner tank assembly 20. For example, a plurality of buckles are disposed on the top of the chassis 30, and a plurality of holes are disposed on the top of the bracket assembly 40 corresponding to the plurality of buckles. The chassis 30 is connected to the bracket assembly 40 through the engagement of the plurality of buckles with the plurality of holes, and the chassis 30 abuts against the side panel of the bracket assembly 40.

[0066] See also Figure 5, which is a schematic diagram of a connector housing according to an embodiment of the present application. Figure 5 As shown, the connector seat 50 is disposed at the bottom of the liner assembly 20, and the connector seat 50 is an independent component and is detachably connected to the chassis 30. Specifically, the connector seat 50 is fixed to the bottom of the liner assembly 20 through a plurality of screws, and abuts against the side wall and bottom of the liner assembly 20 and the side plate of the bracket assembly 40. Further, since the bracket assembly 40 is disposed in the liner assembly 20, the connector seat 50 is also located at the bottom of the bracket assembly 40 and is connected to the bracket assembly 40 through a plurality of screws, the connector seat 50 abuts against the bracket assembly 40, and the chassis 30 abuts against the bracket assembly 40 and the connector seat 50.

[0067] The connector seat 50 includes a fluid connector 51 and a positioning pin 52, which are arranged in parallel. The fluid connector 51 is connected to the liquid outlet 22, and the positioning pin 52 is used to limit the position of the chassis. Specifically, the number of fluid connectors 51 is multiple to form two rows of fluid connectors 51, the number of positioning pins 52 is multiple to form a row of positioning pins 52, a row of positioning pins 52 is arranged between the two rows of fluid connectors 51, and one positioning pin 52 is arranged between two fluid connectors 51. See again Figure 3 , the number of output ports 12 is two, and two rows of fluid connectors 51 connect the two output ports 12. It should be noted that the fluid connector 51 can quickly connect and disconnect the fluid transmission channel (pipeline to pipeline, pipeline to equipment) without tools, and ensure that there will be no leakage of internal fluid during the connection and disconnection process, that is, the fluid connector 51 has a double sealing function.

[0068] It is worth mentioning that since the bracket assembly 40 and the connector housing 50 are independent components and can be adapted according to the specifications and requirements of the chassis 30 and the heating element, a liquid cooling cabinet can be adapted to a variety of heating elements of different specifications by replacing the connector housing 50 of different specifications. In this way, the liquid cooling cabinet can be standardized to significantly improve the applicability of the liquid cooling cabinet, thereby reducing user costs.

[0069] In addition, the outer frame assembly 10, the inner tank assembly 20, the bracket assembly 40 and the connector seat 50 can be assembled separately and simultaneously, thereby improving the assembly efficiency. For example, after the outer frame assembly 10, the inner tank assembly 20, the bracket assembly 40 and the connector seat 50 are assembled, the connector seat 50 and the bracket assembly 40 are fastened with screws to form a new bracket assembly; the new bracket assembly is further fastened to the inner tank assembly 20 with screws to form a new inner tank assembly; finally, the new inner tank assembly is installed in the outer frame assembly to complete the assembly of the liquid cooling cabinet.

[0070] See also Figure 6 as well as Figure 7 , which is a cross-sectional view of an immersion liquid cooling cabinet according to an embodiment of the present application and a schematic diagram of the flow direction of the cooling liquid according to an embodiment of the present application. Figure 6 and Figure 7 As shown, the immersion liquid cooling cabinet 1 includes a radiator 80 , an overflow chamber 90 and an overflow pipe 100 .

[0071] The radiator 80 is disposed in the chassis 30. Specifically, the radiator 80 is disposed in the chassis 30 and is connected to the immersion chamber of the chassis 30. The position of the radiator 80 is higher than the position of the liquid inlet 21 and the position of the liquid outlet 22, but lower than the position of the overflow chamber 90; in other words, the radiator 80 is located between the overflow chamber 90 and the liquid inlet 21, and between the overflow chamber 90 and the liquid outlet 22. In this embodiment, the correspondence between the radiator 80 and the heating element is a many-to-one relationship. For example, two radiators 80 correspond to one heating element; of course, the number of radiators 80 can also be adjusted to more than two according to the heat dissipation requirements of the heating element, and the number of radiators 80 is not limited here. In another embodiment, the correspondence between the radiator 80 and the heating element is a one-to-one relationship; for example, one radiator 80 corresponds to one heating element. According to the above, the radiator 80 is set separately for the heating element, which can ensure the flow of cooling fluid flowing through the heating element.

[0072] Each radiator 80 includes an inlet 81, an outlet 82 and an output pipe 83. The inlet 81 is located above the outlet 82; in other words, the outlet 82 is located below the inlet 81. The inlet 81 is connected to the immersion chamber of the chassis 30, but is not in direct contact with the inner wall of the liner assembly 20. The chassis 30 and the side walls of the liner assembly 20 define a flow space, and the flow space is connected to the inlet 81 and the liquid inlets 21 on both sides. The cooling fluid flows into the flow space from the liquid inlets 21 on opposite sides of the liner assembly 20, and the cooling fluid gradually occupies the flow space; when the liquid level of the cooling fluid in the liner assembly 20 rises to the inlet 81, the cooling fluid flows from the flow space into the immersion chamber, and flows through the heating element to absorb the heat of the heating element.

[0073] The outlet 82 is connected to the immersion chamber and is connected to the fluid connector 51 through the output tube 83. In other words, the output tube 83 connects the fluid connector 51 and the outlet 82, and the outlet 82 is connected to the liquid outlet 22 through the fluid connector 51 and the output tube 83. For example, two outlets 82 correspond to two output tubes 83, and two output tubes 83 correspond to two fluid connectors 51. After absorbing heat, the cooling fluid flows from the two outlets 82 to the two output tubes 83, and flows to the two liquid outlets 22 through the two output tubes 83 and the two fluid connectors 51.

[0074] The overflow chamber 90 is disposed in the inner liner assembly 20 and is located at the top of the inner liner assembly 20. The overflow pipe 100 connects the overflow chamber 90 and the liquid outlet 22. When the liquid level of the cooling fluid in the inner liner assembly 20 rises to the overflow chamber 90, the cooling fluid flows from the overflow chamber 90 into the overflow pipe 100 and flows to the two liquid outlets 22 through the overflow pipe 100.

[0075] See also Figures 8 to 10 , which is a schematic diagram illustrating the cooling liquid entering the immersion liquid cooling cabinet according to an embodiment of the present application. Taking the cooling fluid as the non-conductive cooling liquid CL1 as an example, the mechanism of how the cooling liquid CL1 flows from the liquid inlet 21 into the immersion chamber to cool the heating element is as follows. Figures 8 to 10 Only one chassis 30 is shown, but there may be multiple chassis 30 , which are arranged at intervals, and the number of heating elements accommodated in the immersion cavity of each chassis 30 is at least one. Figures 7 to 9 For the sake of clarity, the heat dissipation mechanism of the immersion liquid cooling cabinet is described using one chassis 30 , but the number of chassis 30 is not limited.

[0076] like Figure 8 As shown, the coolant CL1 flows into the bottom of the inner liner assembly 20 from two liquid inlets 21 on opposite sides of the inner liner assembly 20 , and the coolant CL1 begins to occupy the flow space, and the liquid level of the coolant CL1 in the inner liner assembly 20 gradually rises.

[0077] like Fig. 9 As shown, when the liquid level of the coolant CL1 in the inner tank assembly 20 rises to the inlet 81, the coolant CL1 flows from the inlet 81 to the bottom of the immersion chamber, and the coolant CL1 absorbs the heat generated by the heating element. After absorbing the heat, the liquid level of the coolant CL1 in the immersion chamber gradually rises. Since the position of the radiator 80 is higher than the bottom of the immersion chamber, the gravity accelerates the flow of the coolant CL1 from the top (i.e., the inlet 81) to the bottom (i.e., the bottom of the immersion chamber), and the coolant CL1 strengthens its fluidity under the effect of gravity, so that it can quickly cool the high heat flux density element.

[0078] The heat-absorbing cooling liquid CL1 flows from the two outlets 82 to the two output pipes 83, and flows to the two liquid outlets 22 through the two output pipes 83 and the two fluid connectors 51, so that the heat-absorbing cooling liquid CL1 flows out from the inner tank assembly 20, and no heat-absorbing cooling liquid CL1 remains in the immersion cavity of the chassis 30, thereby avoiding the accumulation of cooling liquid heat caused by the confluence of the hot flow and the cold flow.

[0079] like Fig.10 As shown, when the liquid level of the coolant CL1 in the inner tank assembly 20 rises to the overflow chamber 90 , the coolant CL1 gradually fills the overflow chamber 90 and flows into the overflow pipe 100 , and then the coolant CL1 flows through the overflow pipe 100 to the two liquid outlets 22 .

[0080] In addition, the immersion liquid cooling cabinet 1 may further include a display screen and an electromagnetic exhaust valve. The display screen is arranged on the top cover of the immersion liquid cooling cabinet 1, and a hidden wiring channel is arranged around the top cover of the immersion liquid cooling cabinet 1. The display screen is used to operate the immersion liquid cooling cabinet 1 and monitor the operating conditions of the immersion liquid cooling cabinet 1 and the internal heating elements. Since the immersion liquid cooling cabinet 1 generates a large amount of heat during operation, the pressure inside the immersion liquid cooling cabinet 1 will increase, and the electromagnetic exhaust valve can maintain the pressure inside the immersion liquid cooling cabinet 1 stable in time.

[0081] In summary, in the immersion liquid cooling cabinet of the present application, the coolant flows from the bottom of the inner tank assembly to the inlet higher than the bottom of the inner tank assembly, and then the coolant flows from the inlet to the bottom of the immersion chamber of the chassis under the effect of gravity, thereby improving the fluidity of the coolant. The radiator is set separately for the heating element to ensure the coolant flow to the heating element, and can quickly cool the high heat flux density element.

[0082] In addition, in the immersion liquid cooling cabinet of the present application, the connector seat and the bracket assembly are independent components and can be adjusted according to different specifications of various heating elements, thereby improving the applicability of the liquid cooling cabinet.
