[0036] 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, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0037] The directional terms used in this invention, such as "up," "down," "front," "back," "left," "right," "inner," "outer," and "side," are merely for reference to the accompanying drawings. Therefore, the directional terms used are for explanation and understanding of this invention, and not for limiting it. Furthermore, in the accompanying drawings, structures that are similar or identical are indicated by the same reference numerals.

[0038] Reference Figures 1 to 3 This utility model provides an immersion liquid-cooled chassis. The structure and working principle of the immersion liquid-cooled chassis are described in detail below with reference to the accompanying drawings. The immersion liquid-cooled chassis includes: a chassis body 10, the upper and lower sides of which are hollow, and a strip-shaped opening 101 extending along the side direction on its side wall; and a PCB motherboard 20, detachably assembled inside the chassis body 10, and fully exposed on the upper and lower sides of the chassis body 10.

[0039] In specific implementation, the chassis body 10 is a hollow box structure with open top and bottom sides, meaning the top and bottom of the chassis body 10 are open, directly leading to the interior of the chassis body 10. The interior of the chassis body 10 can be used to accommodate and install various components. A strip-shaped opening 101 is formed on the side wall of the chassis body 10, extending along the side of the chassis body 10. The outside can access the interior of the chassis body 10 through the strip-shaped opening 101. The strip-shaped opening 101 can be set on at least any one side wall of the chassis body 10. To improve heat exchange efficiency, a strip-shaped opening 101 can be formed on the left, right, and rear side walls of the chassis body 10. The PCB motherboard 20 is assembled inside the chassis body 10, fully exposed on the top and bottom sides of the chassis body 10. The PCB motherboard 20 is the main heat dissipation target inside the chassis and can be the motherboard of IT equipment such as a server or switch. In practical applications, since the upper and lower sides of the chassis body 10 are hollow and completely open to the outside, the coolant can circulate through the upper and lower sides of the chassis body 10 and the strip opening 101. The coolant can flow smoothly and unobstructed, and the overall convective heat transfer capacity of the chassis is greatly improved, thus effectively improving the heat dissipation efficiency of the chassis.

[0040] In one embodiment, reference is made to Figures 1 to 4The chassis body 10 includes a front panel 11, a rear fixing plate 12, and two parallel side panels 13. The front panel 11 is fixed to the front ends of the two side panels 13, and the rear fixing plate 12 is detachably connected to the rear ends of the two side panels 13. The PCB motherboard 20 is assembled between the two side panels 13. The front panel 11, the rear fixing plate 12, and the two side panels 13 are all provided with the strip-shaped opening 101. In a specific implementation, the chassis body 10 is composed of a front panel 11, a rear panel, and two side panels 13. The two side panels 13 are arranged parallel to each other. The front panel 11 is fixed together with the front ends of the two side panels 13 to form a U-shaped frame structure. The rear fixing plate 12 is detachably connected to the rear ends of the two side panels 13, that is, the rear fixing plate 12 can be removed from the rear ends of the two side panels 13. The rear fixing plate 12 can enhance the structural strength and stability of the chassis. The PCB motherboard 20 is mounted between the two side panels 13, with both sides perpendicular to the inner sides of the side panels 13. In addition to the front panel 11, the two side panels 13 and the rear mounting plate 12 all have strip-shaped openings 101, thus forming three convection heat exchange channels. The coolant can circulate through the strip-shaped openings 101 on the two side panels 13 and the rear mounting plate 12, greatly improving the overall convection heat exchange capacity of the chassis.

[0041] Furthermore, referring to Figure 5 Both side panels 13 have longitudinal mounting grooves 131 on their inner sides. These grooves extend vertically along the short side of the side panel 13 and penetrate its top. The two ends of the rear fixing plate 12 are located within these longitudinal mounting grooves 131. Specifically, each side panel 13 has a longitudinal mounting groove 131 on its inner side. These grooves extend vertically along the short side of the side panel 13 and penetrate its top. The grooves face each other, with corresponding lengths and positions. The groove width is slightly greater than the thickness of the edges of the rear fixing plate 12, and the groove length is greater than or equal to the width between the upper and lower sides of the rear fixing plate 12. The two ends of the rear fixing plate 12 are located within the longitudinal mounting grooves 131, thus connecting with the two side panels 13. In actual installation, the rear fixing plate 12 can be installed by inserting both ends longitudinally from top to bottom into the longitudinal mounting groove 131. When disassembling, simply pull both ends of the rear fixing plate 12 upward from the longitudinal mounting groove 131 to achieve tool-free installation and disassembly of the rear fixing plate 12.

[0042] Furthermore, referring to Figure 5Each of the two side panels 13 has a transverse mounting groove 132 on its inner side. The transverse mounting groove 132 extends straight along the long side of the side panel 13 and passes through the rear end of the side panel 13. The two sides of the PCB motherboard 20 are located in the transverse mounting groove 132. In a specific implementation, each of the two side panels 13 has a transverse mounting groove 132 on its inner side. The transverse mounting grooves 132 on the two side panels 13 extend straight along the long side of the side panel 13 and pass through the rear end of the side panel 13. The transverse mounting grooves 132 on the two side panels 13 face each other, and their lengths and positions correspond to each other. The groove width is slightly greater than the thickness of the two edges of the PCB motherboard 20, and the groove length is greater than or equal to the length between the front and rear sides of the PCB motherboard 20. The two sides of the PCB motherboard 20 are respectively located in the transverse mounting grooves 132 on the inner side of the two side panels 13, thereby forming a connection with the two side panels 13. In actual installation, the PCB motherboard 20 can be installed by inserting both sides horizontally into the horizontal mounting slot 132. When disassembling, first remove the rear fixing plate 12, and then pull the two sides of the PCB motherboard 20 outward along the horizontal mounting slot 132. Tool-free installation and disassembly of the PCB motherboard 20 can be achieved.

[0043] Furthermore, referring to Figures 4 to 9 The inner side of the side plate 13 is provided with a fixing component 30, which is disposed adjacent to the longitudinal mounting groove 131. Both ends of the rear fixing plate 12 are provided with mounting holes 201. The fixing component 30 is inserted into the mounting holes 201 to connect and fix both ends of the rear fixing plate 12 to the inner sides of the two side plates 13. In a specific implementation, fixing components 30 are provided on the inner sides of both side plates 13, and the fixing components 30 are fixed together with the inner sides of the side plates 13. The number of fixing components 30 on each side plate 13 can be multiple. The fixing component 30 is arranged adjacent to the longitudinal mounting groove 131. Mounting holes 201 are provided at both ends of the rear fixing plate 12. The fixing component 30 connects and fixes the two ends of the rear fixing plate 12 to the inner sides of the two side plates 13 by inserting it into the mounting holes 201. Specifically, after the fixing component 30 is inserted into the mounting holes 201 at both ends of the rear fixing plate 12, the movement of the rear fixing plate 12 is restricted, so it cannot move along the longitudinal mounting groove 131, thereby enhancing the connection stability between the rear fixing plate 12 and the two side plates 13.

[0044] Furthermore, referring to Figures 4 to 9The inner side of the side plate 13 is provided with a fixing component 30, which is adjacent to the transverse mounting groove 132. Mounting holes 201 are provided on both sides of the PCB motherboard 20. The fixing component 30 is inserted into the mounting holes 201 to connect and fix both sides of the PCB motherboard 20 to the inner sides of the two side plates 13. In specific implementation, fixing components 30 are provided on the inner sides of both side plates 13, and the fixing components 30 are fixed together with the inner sides of the side plates 13. Multiple fixing components 30 are provided on each side plate 13, and all fixing components 30 are evenly distributed along the direction of extension of the transverse mounting groove 132, with each fixing component 30 adjacent to the transverse mounting groove 132. The two sides of the PCB motherboard 20 are provided with mounting holes 201 corresponding to the number of fixing components 30. The fixing components 30 are inserted into the mounting holes 201 to connect and fix the two sides of the PCB motherboard 20 to the inner sides of the two side plates 13. Specifically, after the fixing components 30 are inserted into the mounting holes 201 on the two sides of the PCB motherboard 20, the movement of the PCB motherboard 20 is restricted, so that it cannot move along the transverse mounting groove 132, so that the PCB motherboard 20 is fixed together with the two side plates 13 and there will be no shaking.

[0045] In one embodiment, reference is made to Figures 10 to 16The fixing component 30 includes a housing 31 and a pin 32. The housing 31 is fixed to the inner side of the side plate 13. The housing 31 has a through hole 301, which is axially aligned with the mounting hole 201. The pin 32 is movably inserted into the through hole 301 and is used to insert into the mounting hole 201. In a specific implementation, the fixing component 30 includes a housing 31 and a pin 32. The housing 31 is fixed to the inner side of the side plate 13 and serves as the main structure for mounting the pin 32. For the fixing component 30 used to install the rear fixing plate 12, its housing 31 is adjacent to the longitudinal mounting groove 131. For the fixing component 30 used to install the rear PCB motherboard 20, its housing 31 is adjacent to the transverse mounting groove 132. A through hole 301 is provided on the housing 31. The through hole 301 is a through-hole structure with open ends. The through hole 301 is axially aligned with the mounting hole 201. Specifically, for the fixing component 30 used to install the rear fixing plate 12, the through hole 301 on the housing 31 is axially aligned with the mounting hole 201 on the rear fixing plate 12. For the fixing component 30 used to install the rear PCB motherboard 20, the through hole 301 on the housing 31 is axially aligned with the mounting hole 201 on the PCB motherboard 20. A pin 32 is movably inserted into the through hole 301. The length of the pin 32 is greater than the length of the through hole 301. Both ends of the pin 32 can extend from both sides of the housing 31. The pin 32 as a whole can move along the axial direction of the through hole 301 to be inserted into the mounting hole 201. Specifically, for the fixing component 30 of the rear fixing plate 12, the corresponding pin 32 is inserted into the mounting hole 201 on the rear fixing plate 12 through its end, thereby restricting the movement of the rear fixing plate 12 and fixing the rear fixing plate 12 to the two side plates 13. When it is necessary to remove the rear fixing plate 12, the pin 32 is moved axially away from the mounting hole 201 along the through hole 301, and the end of the pin 32 is pulled out from the mounting hole 201. Then, the entire rear fixing plate 12 can be pulled out along the longitudinal mounting groove 131. The fixing component 30 for mounting the PCB motherboard 20 has corresponding pins 32 that are inserted into the mounting holes 201 on both sides of the PCB motherboard 20, thereby restricting the movement of the PCB motherboard 20 and fixing the PCB motherboard 20 to the two side plates 13. When it is necessary to remove the PCB motherboard 20, the pins 32 are moved axially away from the mounting holes 201 along the through holes 301, and the ends of the pins 32 are pulled out from the mounting holes 201. Then, the entire PCB motherboard 20 is pulled out along the transverse mounting groove 132. When installing the mounting plate 12 or the PCB motherboard 20, first adjust the position of the mounting plate and the PCB motherboard 20 so that the mounting holes 201 and the pins 32 are aligned. Then, the pins 32 are moved so that their ends are inserted into the mounting holes 201 to complete the installation. This truly achieves tool-free installation of the mounting plate 12 and the PCB motherboard 20.

[0046] Furthermore, referring to Figure 12 and Figure 13 as well as Figure 15 and Figure 16 The fixing component 30 also includes a spring 33. The inner wall of the through hole 301 is recessed away from the axis to form a limiting notch 311. The outer radial side of the pin 32 is provided with a limiting flange 321. A locking portion 322 extends outward from the limiting flange 321. The inner wall of the through hole 301 near the mounting hole 201 protrudes towards the axis to form a first stop portion 312. The inner wall of the through hole 301 away from the mounting hole 201 protrudes towards the axis to form a second stop portion 313. The limiting flange 321 is movably disposed between the first stop portion 312 and the second stop portion 313. 3. The limiting flange 321 is blocked. The spring 33 is sleeved on the pin 32, with one end elastically pressing against the limiting flange 321 and the other end elastically pressing against the first stop portion 312. The locking portion 322 is movably disposed in the limiting notch 311. The limiting notch 311 restricts the pin 32 from moving away from the mounting hole 201 along the axial direction of the through hole 301 by blocking the locking portion 322. When the pin 32 rotates at a certain angle, the locking portion 322 disengages from the limiting notch 311, allowing the pin 32 to move away from the mounting hole 201 along the axial direction of the through hole 301. In specific implementations, such as... Figure 13 and Figure 16As shown, the fixing assembly also includes a spring 33. The inner wall of the through hole 301 is recessed away from the axis to form a limiting notch 311. The spring 33 is sleeved on the part of the pin 32 located in the housing 31. The limiting flange 321 protrudes on the outside of the pin 32. The locking part 322 is a part of the limiting flange 321 extending outward. The inner wall of the through hole 301 near the mounting hole 201 protrudes towards the axis to form a first stop portion 312, and the inner wall of the through hole 301 away from the mounting hole 201 protrudes towards the axis to form a second stop portion 313. Specifically, the first stop portion 313 and the second stop portion 313 are structures in which the two ends of the through hole 301 protrude inward, so that the diameter at both ends of the through hole 301 is smaller than the diameter of the middle part. The space between the first stop portion 312 and the second stop portion 313 in the through hole 301 can allow the limiting flange 321, the locking portion 322 and the spring 33 to move. The limiting flange 321 is movably disposed between the first stop portion 312 and the second stop portion 313, that is, the limiting flange 321 can move between the first stop portion 312 and the second stop portion 313 in the through hole 301. The second stop 313 blocks the limiting flange 321, preventing the limiting flange 321 from disengaging from the through hole 301, thus preventing the pin 32 from disengaging from the housing 31. The spring 33 is entirely sleeved on the pin. When the pin 32 is inserted into the mounting hole 201, the spring 33 is in an elastically compressed state. One end of the spring 33 elastically presses against the limiting flange 321, and the other end of the spring 33 elastically presses against the first stop 312. The locking part 322 is movably disposed in the limiting notch 311. Under the elastic force of the spring 32, the locking part 322 on the pin 32 elastically presses against the side wall of the limiting notch 311. The limiting notch 311 restricts the pin 32 from moving away from the mounting hole 201 along the axial direction of the through hole 301 by blocking the locking part 322, thereby locking the pin 32 and keeping the end of the pin 32 in a locked state inserted into the mounting hole 201. When the pin 32 rotates at a certain angle, the locking part 322 disengages from the limiting notch 311 and is no longer blocked by the limiting notch 311. Under the elastic force of the spring 33, the limiting flange 321 moves toward the second stop part 313. Since the second stop part 313 blocks the limiting flange 321, the limiting flange 321 finally abuts against the second stop part 313. The movement of the limiting flange 321 causes the pin 32 to move outward along the axial direction of the through hole 301 away from the mounting hole 201, so that the end of the pin 32 is disengaged from the mounting hole 201, thereby releasing the fixation between the rear fixing plate 12 or PCB main board 20 and the two side plates 13. At this time, the fixing plate or PCB main board 20 can be removed.When it is necessary to fix the rear fixing plate 12 or the PCB motherboard 20, the pin 32 is moved along the axial direction of the through hole 301 towards the mounting hole 201, so that the end of the pin 32 is inserted into the mounting hole 201. When the locking part 322 reaches the position of the limiting notch 311, the pin 32 is rotated to make the locking part 322 in the limiting notch 311. Under the elastic force of the spring 33, the locking part 322 on the pin 32 is elastically pressed against the side wall of the limiting notch 311 to achieve locking, so that the pin 32 as a whole remains stable, thereby firmly fixing the PCB motherboard 30, the rear fixing plate 12 and the side plate 13.

[0047] Furthermore, to facilitate the installation of the pin 32 and the spring 33, the housing 31 of the fixing assembly 30 is obtained by splicing two parts together. The splicing surface of the housing 31 passes through the central axis of the through hole 301. The housing 31 is divided into two halves, and the through hole 301 is located on the two halves of the housing 31 respectively. When installing the pin 32 and the spring 33, first open the housing 31 to expose one half of the through hole 301. Then, put the spring 33 onto the pin 32 so that one end of the spring 33 abuts against the limiting flange 321 on the pin 32. Then, insert the pin 32 with the spring 33 onto the through hole 301 of the other half of the housing 31 and adjust the pin 32 and the spring 33 to the correct position. Then, splice the other half of the housing 31. Finally, weld the two halves of the housing 31 together or fix them together with glue.

[0048] In one embodiment, reference is made to Figure 17 The front panel 11 has multiple first openings 102 and second openings 103, with the first openings 102 and second openings 103 adjacent to each other, and the area of ​​the first opening 102 being larger than the area of ​​the second opening 103. In a specific implementation, the front panel 11 of the chassis body 10 has multiple first openings 102 and second openings 103, and the external interfaces of the PCB motherboard 20 are led out through the first openings 102 and second openings 103 on the front panel 11, without the need for additional adapter cables. Multiple first openings 102 are distributed vertically, horizontally, and vertically. Second openings 103 are located to one side of the first openings 102. Depending on their function, the area of ​​the first openings 102 is larger than that of the second openings 103. The first openings 102 are mainly used to connect the hard drive or expansion card interface of the PCB motherboard 20.
