Three power supply bodies 3 are equidistantly distributed on the top of the mounting plate 2. Mounting holes respectively located on the three power supply bodies 3 are opened on the top of the mounting plate 2. A heat exchange pump 4 is slidably installed on the inner side of the mounting hole. An upper pipe 5 is fixedly installed on the inner side of the cabinet 1 for conveying cooled water. A lower pipe 6 fixedly installed on the inner side of the cabinet 1 is arranged below the upper pipe 5 for conveying water that absorbs the heat of the power supply body 3; it also includes: a cooling mechanism for quickly installing and cooling the power supply body 3, and the cooling mechanism is installed on the outer side of the mounting plate 2; a disassembly mechanism for quickly disassembling the heat exchange pump 4, and the disassembly mechanism is installed on the bottom inner wall of the cabinet 1; a leak-proof mechanism for disassembling the heat exchange pump 4 to prevent water leakage, and the leak-proof mechanism is installed on the inner side of the cabinet 1.

[0031] The cooling mechanism includes two plug-in boards 7 symmetrically fixedly installed on the outside of the power supply body 3, an L-shaped plug-in frame 8 is arranged on the outside of the plug-in board 7, three nut seats 9 distributed at equal distances are fixedly installed on the top of the L-shaped plug-in frame 8, bolts 10 are installed on the inner side of the nut seat 9, screw holes matching with the bolts 10 are provided on the top of the plug-in board 7, the plug-in board 7 is fixed in the L-shaped plug-in frame 8 by the bolts 10, the bottom of the plug-in board 7 is in contact with the top of the mounting plate 2, a mounting ring 11 is arranged on the outside of the heat exchange pump 4, and an annular groove for limiting the insertion of the mounting ring 11 is provided on the bottom of the mounting plate 2, and the outside of the heat exchange pump 4 is fixed A positioning ring 12 is installed below the mounting ring 11, and a plurality of support rods 13 are fixedly installed at the bottom of the mounting ring 11, which are centrally symmetrical and slide through the positioning ring 12 to provide guidance for the movement of the heat exchange pump 4. A bottom ring 14 is provided below the mounting ring 11, and the bottom end of the support rod 13 is fixedly installed on the top of the bottom ring 14. A spring 15 is provided on the outside of the support rod 13, and the spring 15 is fixedly installed between the bottom ring 14 and the positioning ring 12, so that the heat exchange pump 4 is close to the bottom of the power supply body 3. The top of the heat exchange pump 4 is an annular inclined surface structure, which is convenient for the power supply body 3 to push the heat exchange pump 4 to move downward;

[0032] The power supply body 3 can be inserted into the inner side of the L-shaped insertion frame 8 through two insertion plates 7, so that the L-shaped insertion frame 8 can provide pre-positioning for the power supply body 3, which is convenient for the bolts 10 on the nut seat 9 to dock with the screw holes on the insertion plate 7, thereby improving the convenience of installing the power supply body 3. When the bottom of the power supply body 3 contacts the annular inclined surface of the heat exchange pump 4, the heat exchange pump 4 can be pushed to move downward. By utilizing the elasticity of the spring 15, the heat exchange pump 4 can be tightly attached to the bottom of the power supply body 3, and can quickly absorb the heat of the power supply body 3, thereby achieving the effect of rapid cooling and installation.

[0033] Working principle: First, the staff opens the cabinet 1, aligns the plug board 7 on the power supply body 3 with the two symmetrical L-shaped plug frames 8, inserts the plug board 7 into the inner side of the L-shaped plug frame 8, and aligns the three screw holes on the plug board 7 with the three nut seats 9 on the L-shaped plug frame 8 respectively, so that the L-shaped plug frame 8 pre-positions the power supply body 3 through the plug board 7. At the same time, the bottom of the power supply body 3 contacts the top of the mounting plate 2, so that the bottom of the power supply body 3 contacts the annular inclined surface on the heat exchange pump 4, and pushes the heat exchange pump 4 to move downward along the mounting hole on the mounting plate 2. The heat exchange pump 4 drives the positioning ring 12 to move downward along the outer side of the support rod 13 at the bottom of the mounting ring 11, and presses the spring 15, and uses the elasticity of the spring 15 to force so that the top of the heat exchange pump 4 is tightly against the bottom of the power supply body 3, and then the staff turns the bolt 10 on the nut seat 9 to fix the bolt 10 on the screw hole of the plug plate 7. Thus, the staff installs the other two power supply bodies 3 in turn to complete the installation of the cabinet 1. The upper pipe 5 can transport cooled water to the heat exchange pump 4, and conduct the temperature of the power supply body 3 to the water in the heat exchange pump 4 through the top of the heat exchange pump 4, and discharge it into the lower pipe 6 to take away the heat. A pair-by-pair cooling method is adopted to make the three heat exchange pumps 4 cool down the three power supply bodies 3 respectively, thereby achieving a rapid cooling effect, and improving the convenience of installation and disassembly of the power supply body 3, ensuring the normal operation of the power supply body 3.

[0034] Example 2: Please refer to Figure 3-Figure 6, this embodiment further explains the first embodiment. The disassembly and assembly mechanism shown in the figure includes wing plates 16 fixedly installed on both sides of the mounting ring 11. The bottom of the mounting plate 2 is provided with a groove for the wing plate 16 to limit and insert. The bottom of the wing plate 16 is provided with a top frame 17. The top frame 17 is used to press the bottom of the wing plate 16 so that the mounting ring 11 is fixed in the annular groove of the mounting plate 2. A moving block 18 is fixedly installed at the bottom end of the top frame 17. A mounting frame 19 is fixedly installed below the moving block 18. A screw 20 that cooperates with the moving block 18 is rotatably installed on the inner side of the mounting frame 19. The moving block 18 is slidably installed on the outer side of the mounting frame 19. The top frame 17 is slidably installed on the top of the mounting frame 19. Rotating the screw 20 can drive the moving block 18 to move upward along the outer side of the mounting frame 19. Three equally spaced butt joints 21 are fixedly installed on the outer side of the upper pipe 5 and the outer side of the lower pipe 6. A butt joint 22 is provided at the end of the butt joint 21 away from the upper pipe 5. The second connecting pipe 22 is an L-shaped structure. A sleeve 23 is slidably installed at one end of the connecting pipe 22 away from the connecting pipe 1 21. The sleeve 23 is fixedly installed at the bottom of the heat exchange pump 4. The heat exchange pump 4 is connected to the two connecting pipes 22 through the two sleeves 23. A limit ring 24 is fixedly installed at one end of the connecting pipe 22 away from the connecting pipe 1 21, so that the connecting pipe 22 can move on the inner side of the sleeve 23 through the limit ring 24. The limit ring 24 is slidably installed on the inner side of the sleeve 23. A convex ring is provided on the outer side of the second 22, and a spring 25 is fixedly installed between the convex ring and the bottom end of the sleeve 23 to facilitate the movement and reset of the second sleeve 22. The bottom end of the screw rod 20 extends to the bottom of the cabinet 1, and three equidistantly distributed adjustment dials 35 are rotatably installed on the bottom inner wall of the cabinet 1. A synchronous belt 36 is rotatably installed between two adjacent screw rods 20 and adjacent adjustment dials 35. The synchronous belt 36 is located at the bottom of the cabinet 1 to facilitate synchronous adjustment of the two adjacent screw rods 20.

[0035] In this embodiment: the staff can rotate the adjusting dial 35 so that the adjusting dial 35 drives the corresponding two screws 20 to rotate synchronously through the synchronous belt 36, so that the screw 20 drives the moving block 18 to move downward along the outer side of the mounting frame 19, and the moving block 18 drives the top frame 17 to move downward, so that the top frame 17 is away from the wing plate 16 on the mounting ring 11. At this time, the staff pulls down the bottom ring 14, so that the bottom ring 14 drives the mounting ring 11 to be pulled out of the annular groove on the mounting plate 2 through the support rod 13, and the heat exchange pump 4 drives the sleeve 23 to move downward along the outer side of the docking pipe 22, so that the heat exchange pump 4 is away from the mounting plate 2, and the heat exchange pump 4 can be removed, which is convenient for the later inspection and maintenance of the heat exchange pump 4, and the normal operation of the power supply body 3 is ensured, thereby achieving the effect of facilitating disassembly and maintenance.

[0036] Example 3: Please refer to Figure 7 and Figure 8, this embodiment further illustrates other embodiments, the leakage prevention mechanism shown in the figure includes a plug 26 fixedly installed on the inner side of the second connecting pipe 22, one end of the plug 26 extends to the outer side of the second connecting pipe 22, a cross bracket 27 is fixedly installed on the inner side of the plug 26, a mounting rod 28 is slidably installed on the inner side of the cross bracket 27, a sealing column 29 is fixedly installed on one end of the mounting rod 28, and the end of the sealing column 29 away from the mounting rod 28 is a hemispherical structure, and a water inlet hole for limiting the insertion of the sealing column 29 is opened on the outer side of the plug 26, and the outer diameter of the water inlet hole is smaller than the outer diameter of the sealing column 29, and a spring three 30 is fixedly installed between the sealing column 29 and the cross bracket 27, so that the sealing column 29 contacts the water inlet hole by the elastic force of the spring three 30, so as to achieve the sealing of the plug 26, and a stopper 31 is fixedly installed on the inner side of the connecting pipe 1 21, and the connecting pipe 1 21 is close to the water inlet hole. A socket for limiting the insertion of the insert pipe 26 is provided at one end near the connecting pipe 22, and a plurality of drainage grooves symmetrically distributed in the center are provided on the outer side of the block 31 to facilitate the water in the connecting pipe 1 21 to flow through the drainage grooves. A push rod 32 is fixedly installed on the end of the block 31 near the connecting pipe 22, and the outer diameter of the push rod 32 is smaller than the inner diameter of the water inlet hole on the insert pipe 26, so that the push rod 32 can push the sealing column 29 to move, and four springs 4 33 symmetrically distributed in the center are fixedly installed on the side of the block 31 near the push rod 32, and four limit blocks 34 symmetrically distributed in the center and in contact with the side of the block 31 away from the spring 4 33 are fixedly installed on the inner side of the connecting pipe 1 21, providing a limit for the movement of the block 31, and the elastic potential energy of the spring 30 is greater than the sum of the elastic potential energy of the four springs 4 33, so that the sealing column 29 can push the block 31 to move through the push rod 32.

[0037] In this embodiment, when the docking pipe 1 21 is docked with the docking pipe 2 22, the insert pipe 26 on the docking pipe 2 22 can be inserted into the insertion hole on the docking pipe 1 21, so that the push rod 32 on the stopper 31 contacts the sealing column 29 in the insert pipe 26. Since the elastic potential energy of the spring 30 is greater than the sum of the elastic potential energy of the four springs 33, the sealing column 29 pushes the stopper 31 to move along the inner side of the docking pipe 1 21 through the push rod 32, so that the stopper 31 is away from the insertion hole of the docking pipe 1 21. Subsequently, the stopper 31 contacts the limit block 34. Under the support of the limit block 34, the push rod 32 pushes the sealing column 29 to compress the spring 30, and the sealing column 29 opens the water inlet hole of the insert pipe 26, so that the docking pipe 1 21 is opened. The water in the connecting pipe 21 can enter the insert pipe 26 through the drainage groove of the block 31 and enter the connecting pipe 22, thereby realizing the rapid opening and docking of the connecting pipe 21 and the connecting pipe 22. When the connecting pipe 21 and the connecting pipe 22 move away from each other, the insert pipe 26 moves along the insertion hole on the connecting pipe 21, and the rebound force of the spring four 33 is utilized to make the insert pipe 26 contact with the insertion hole of the connecting pipe 21 when moving, thereby realizing the sealing of the connecting pipe 21. At the same time, the push rod 32 is away from the sealing column 29, and the rebound force of the spring three 30 is utilized to make the spring three 30 quickly seal the water inlet of the insert pipe 26, thereby achieving the effect of disassembly and leakage prevention, and improving the convenience of installation of the heat exchange pump 4.

[0038] Example 4: Please refer to Figure 4-Figure 8 , this embodiment further illustrates other embodiments. A protrusion is fixedly installed on the top of the top frame 17 in the figure, and a strip opening is opened on the outer side of the wing plate 16 for the protrusion to limit and insert, so as to facilitate the alignment of the top frame 17 and the wing plate 16. The end of the butt joint pipe 22 close to the sleeve 23 is a prismatic structure to prevent the butt joint pipe 22 from swinging in the sleeve 23. A guide rod 37 that slides through the stopper 31 is fixedly installed between the limit block 34 and the inner side of the butt joint pipe 1 21 to provide guidance for the movement of the stopper 31. A rubber ring 38 is fixedly installed on the end of the butt joint pipe 1 21 that contacts the butt joint pipe 2 22 to improve the sealing between the butt joint pipe 1 21 and the butt joint pipe 2 22.

[0039] In this embodiment: when the wing plate 16 is docked with the top of the top frame 17, the strip opening on the wing plate 16 can dock with the protrusion on the top frame 17, thereby improving the convenience of docking the wing plate 16 with the top frame 17 and facilitating the top frame 17 to quickly push the wing plate 16 to move. The prismatic structure on the docking tube 22 can prevent the docking tube 22 from offsetting when moving up and down, thereby facilitating the docking of the docking tube 1 21 with the docking tube 2 22. When the stopper 31 moves, it can move along the outer side of the guide rod 37 to provide guidance for the movement of the stopper 31, thereby improving the stability of the movement of the stopper 31. When the docking tube 1 21 is docked with the docking tube 2 22, the two rubber rings 38 that contact each other can improve the sealing between the docking tube 1 21 and the docking tube 2 22.
