[0061] Please see Figure 1 , Figure 1 A perspective view of an immersion cooling tank 10 and an electronic device 20 according to an embodiment of the present invention is shown. The immersion cooling tank 10 includes an outer tank body 100 and an inner tank body assembly 200. The inner tank body assembly 200 is used to accommodate a plurality of electronic devices 20 and a coolant (not shown), and the inner tank body assembly 200 is inserted into the outer tank body 100. In some embodiments, the electronic device 20 is, for example, a server, and the coolant is, for example, a single-phase coolant or a two-phase coolant.

[0062] One installation method involves first inserting the inner tank assembly 200 into the outer tank 100, and then inserting multiple electronic devices 20 into the inner tank assembly 200. Another installation method involves first inserting multiple electronic devices 20 into the inner tank assembly 200, and then inserting the multiple electronic devices 20 and the inner tank assembly 200 together into the outer tank 100. These two installation methods correspond to two disassembly methods. Therefore, this invention provides multiple installation and disassembly methods to adapt to various operational needs, such as single or batch disassembly and assembly operations. Because the inner tank assembly 200 has an opening O, regardless of whether coolant is injected into the inner tank assembly 200 or the outer tank 100, the coolant can flow between the inner tank assembly 200 and the outer tank 100 through the opening O. When performing batch disassembly operations, that is, when multiple electronic devices 20 and inner tank assembly 200 are moved out of outer tank 100 together, the coolant in inner tank assembly 200 flows downward under the influence of gravity and flows downward through opening O to outer tank 100, so no additional device is needed to recover the coolant.

[0063] Please see Figure 2 , Figure 2An exploded view of the inner tank assembly 200 according to an embodiment of the present invention is shown. The inner tank assembly 200 includes a base plate 210, four side walls 220a, 220b, 220c, and 220d, an assembly frame 230, and a busbar 240. The four side walls 220a, 220b, 220c, and 220d are connected to the base plate 210, and one of the four side walls 220a, 220b, 220c, and 220d forms an opening O. The assembly frame 230 is disposed on the base plate 210. The busbar 240 is slidably assembled to the assembly frame 230 in the X direction via the opening O and is used to supply power to the electronic device 20. When only the busbar 240 needs to be repaired or replaced, multiple electronic devices 20 and inner tank assembly 200 can be moved out of the outer tank 100 together, and then another prepared busbar 240 can be replaced through the opening O. This improves the ease of operation and reduces downtime.

[0064] In some embodiments, the inner tank assembly 200 may further include four inner liner pads 250a, 250b, 250c, and 250d. The four inner liner pads 250a, 250b, 250c, and 250d are respectively disposed within the four sidewalls 220a, 220b, 220c, and 220d. The rigidity of the four inner liner pads 250a, 250b, 250c, and 250d is less than the rigidity of the housing of the electronic device 20. The inner liner pads 250a, 250b, 250c, and 250d are made of a softer material to prevent scratching the housing of the electronic device 20. Furthermore, the inner liner pads 250a, 250b, 250c, and 250d are made of a non-conductive material (e.g., bakelite) to prevent metal debris from floating within the inner tank assembly 200 and causing a short circuit.

[0065] In some embodiments, a first inner liner 250a, comprising four inner liners 250a, 250b, 250c, and 250d, is provided with a plurality of first guide grooves 251a. The plurality of first guide grooves 251a extend along a Z-direction and are used to guide the electronic device 20 into the inner housing assembly 200. The housing of the electronic device 20 is provided with at least one first guide protrusion 21. Operationally, when the first guide protrusion 21 enters the first guide groove 251a, the electronic device 20 is restricted from moving along the Z-direction, thereby preventing the electronic device 20 from wobbling during movement.

[0066] In some embodiments, the inner tank assembly 200 may further include a first compartment 260, a plurality of presence sensing circuits 270, and a plurality of sensing units 280. The first compartment 260 is disposed outside a first sidewall 220a of the four sidewalls 220a, 220b, 220c, and 220d. The plurality of presence sensing circuits 270 are disposed within the first compartment 260. The plurality of sensing units 280 are respectively connected to the plurality of presence sensing circuits 270 and are used to sense the presence of the electronic device 20. A first inner liner 250a has a plurality of receiving grooves 252a. The plurality of receiving grooves 252a are respectively located between two of the plurality of first guide grooves 251a, and the plurality of sensing units 280 are respectively disposed in the plurality of receiving grooves 252a.

[0067] In one embodiment, the presence sensing circuit 270 and the sensing unit 280 can be combined into a limit switch. When the electronic device 20 is not inserted into the inner cavity assembly 200, the sensing unit 280 protrudes from the receiving groove 252a, and the presence sensing circuit 270 is not triggered. Conversely, when the electronic device 20 enters the inner cavity assembly 200, it interferes with the sensing unit 280, causing the sensing unit 280 to retract into the receiving groove 252a, thereby triggering the presence sensing circuit 270. Therefore, when the presence sensing circuit 270 is triggered, the presence of the electronic device 20 inside the inner cavity assembly 200 can be detected.

[0068] In some embodiments, the inner tank assembly 200 may further include a plurality of first wedges 290 and a plurality of first covers 300. The plurality of first wedges 290 are disposed within the first compartment 260 and are used to guide the electronic device 20 into the inner tank assembly 200. The plurality of first covers 300 are respectively disposed between two of the plurality of first wedges 290 and are used to cover the plurality of presence sensing circuits 270.

[0069] In some embodiments, the first inclined surface 291 of the plurality of first wedges 290 is adjacent to the top inclined surface 253a of the first inner liner 250a, and the width of the plurality of first wedges 290 in a Y direction gradually widens from the top to the bottom of the inner groove assembly 200. In other words, the projection of the inner groove assembly 200 in the YZ plane presents a funnel shape, which can guide the electronic device 20 to move into the inner groove assembly 200 along the first inclined surface 291 of the first wedges 290 and the top inclined surface 253a of the first inner liner 250a when the electronic device 20 approaches the inner groove assembly 200.

[0070] Please see Figure 3 , Figure 3An exploded view of the inner tank assembly 200 according to an embodiment of the present invention is shown. In some embodiments, a second inner liner 250b of the four inner liners 250a, 250b, 250c, and 250d is formed with a plurality of second guide grooves 251b. The plurality of second guide grooves 251b extend along the Z direction and are used to guide the electronic device 20 into the inner tank assembly 200. The housing of the electronic device 20 is provided with at least one second guide protrusion 22. In operation, when the second guide protrusion 22 enters the second guide groove 251b, the electronic device 20 is restricted from moving along the Z direction, thereby preventing the electronic device 20 from shaking during movement.

[0071] The first inner liner 250a and the second inner liner 250b are disposed opposite to each other, and the widths of the first guide groove 251a and the second guide groove 251b are different in one X direction. Similarly, the widths of the first guide protrusion 21 and the second guide protrusion 22 on the housing of the electronic device 20 are also different, corresponding to the widths of the first guide groove 251a and the second guide groove 251b, respectively. It is worth noting that, because the widths of the first guide groove 251a and the second guide groove 251b are different, the electronic device 20 can be prevented from being inserted into the bottom busbar 240 in the wrong direction, thus achieving a foolproof effect.

[0072] In some embodiments, the inner tank assembly 200 may further include a second compartment 310, a plurality of second wedges 320, and a plurality of second covers 330. The second compartment 310 is disposed outside a second sidewall 220b of the four sidewalls 220a, 220b, 220c, and 220d. The plurality of second wedges 320 are disposed within the second compartment 310 and are used to guide the electronic device 20 into the inner tank assembly 200. The plurality of second covers 330 are respectively disposed between two of the plurality of second wedges 320.

[0073] In some embodiments, the second inclined surfaces 321 of the plurality of second wedges 320 are adjacent to the top inclined surface 252b of the second inner liner 250b, and the width of the plurality of second wedges 320 in a Y direction gradually widens from the top to the bottom of the inner groove assembly 200. In other words, the projection of the inner groove assembly 200 in the YZ plane presents a funnel shape, which can guide the electronic device 20 to move into the inner groove assembly 200 along the second inclined surfaces 321 of the second wedges 320 and the top inclined surface 252b of the second inner liner 250b when the electronic device 20 approaches the inner groove assembly 200.

[0074] In some embodiments, an opening O is formed in a third sidewall 220c of the four sidewalls 220a, 220b, 220c, 220d and a third inner liner 250c of the four inner liners 250a, 250b, 250c, 250d, and the opening O is located at the bottom of the third sidewall 220c and the third inner liner 250c.

[0075] Please see Figure 4 , Figure 4 A partial perspective view of the inner groove assembly 200 according to some embodiments of the present invention is shown. In some embodiments, the assembly frame 230 is formed with a plurality of guide holes 231, and the plurality of guide holes 231 are used for multiple guide posts 23 of a plurality of electronic devices 20 (e.g., Figure 2 (As shown) Insertion. It is worth noting that before the electronic device 20 is inserted into the busbar 240, the guide post 23 of the electronic device 20 is first inserted into the guide hole 231, so as to perform pre-alignment and improve the accuracy of the electronic device 20 being inserted into the busbar 240.

[0076] In some embodiments, the assembly frame 230 has a plurality of first guide holes 231 and a plurality of second guide holes 232, wherein the busbar 240 is located between the plurality of first guide holes 231 and the plurality of second guide holes 232, and a first distance D1 between the first guide holes 231 and the busbar 240 is different from a second distance D2 between the second guide holes 232 and the busbar 240. This prevents the electronic device 20 from being inserted into the bottom busbar 240 in the wrong direction, thus achieving a foolproof effect.

[0077] In some embodiments, the inner tank assembly 200 may further include a bottom liner 340 and a mesh plate 350. The bottom liner 340 is disposed on the base plate 210, and the assembly frame 230 is fixed to the bottom liner 340. The mesh plate 350 is connected to the assembly frame 230 and is disposed between the bottom liner 340 and the assembly frame 230 to adjust the flow field of the coolant. It is worth noting that the coolant used in single-phase immersion cooling technology has a higher viscosity, and the mesh plate 350 can be used to adjust the flow field of the coolant.

[0078] Please see Figures 5 to 7 . Figures 5 to 7 The process of assembling the electronic device 20 of this embodiment of the invention into the inner tank assembly 200 is illustrated. Figure 5 As shown, firstly, the electronic device 20 can be moved above the inner tank assembly 200 using a gantry crane, and then the electronic device 20 is lowered along the Z direction, so that the bottom of the electronic device 20 passes through multiple first wedges 290 (e.g., Figure 2 (as shown) and multiple second wedges 320 (as shown) Figure 3 As shown, the upper guide provides entry into the inner tank assembly 200.

[0079] like Figure 6As shown, during the movement of the electronic device 20 toward the base plate 210 of the inner tank assembly 200, the first guide protrusion 21 and the second guide protrusion 22 of the electronic device 20 respectively enter the first guide groove 251a and the second guide groove 251b, thereby providing mid-section guidance to the electronic device 200. The combination of different widths of the first guide groove 251a and the second guide groove 251b, and different widths of the first guide protrusion 21 and the second guide protrusion 22, provides a foolproof mechanism to prevent incorrect installation of the electronic device 20.

[0080] In addition, such as Figure 6 As shown, during the movement of the electronic device 20 toward the base plate 210 of the inner tank assembly 200, the electronic device 20 will come into contact with the sensing unit 280, and the presence will be detected via the corresponding presence sensing circuit 270 (e.g., Figure 2 (As shown) The signal is transmitted to a monitoring system to inform the electronic device 20 of its presence.

[0081] like Figure 7 As shown, when the electronic device 20 approaches the bottom plate 210 of the inner tank assembly 200, the guide post 23 of the electronic device 20 inserts into the guide hole 231 of the assembly frame 230, so that the electronic device 20 is guided by the bottom section provided by the inner tank assembly 200 to achieve precise alignment between the electronic device 20 and the busbar 240. In this way, the electronic device 20 can be accurately assembled with the busbar 240. In addition, since the first distance D1 between the first guide hole 231 and the busbar 240 is different from the second distance D2 between the second guide hole 232 and the busbar 240, it can prevent the electronic device 20 from being inserted into the bottom busbar 240 in the opposite direction, which would cause a short circuit.

[0082] In summary, the inner tank assembly and immersion cooling tank of this utility model have the following features: (1) The inner tank assembly and the multiple electronic devices it contains can be moved into or out of the outer tank together, thereby improving assembly convenience. (2) The modular inner tank assembly increases versatility and design efficiency, and is suitable for immersion cooling tanks of any size and single-phase or two-phase liquid cooling systems. (3) The configuration of the assembly rack on the bottom plate of the inner tank assembly through the side wall openings of the inner tank assembly, and the slidable assembly of the busbars to the bottom plate of the inner tank assembly through the openings, facilitates the user's disassembly and assembly of the busbars through the openings. (4) The inner tank assembly provides upper, middle and bottom guides to increase the accuracy of electronic device installation and avoid collision damage. (5) The inner tank assembly provides slot installation detection to detect whether each slot is equipped with an electronic device.
