The water outlet end of the cooling unit 1 is connected to the water main pipe 1 2, the return water end of the cooling unit 1 is connected to the water main pipe 2 3, the water main pipe 1 2 is connected to a plurality of delivery pipes 1 5, a plurality of delivery pipes 1 5 are provided, adjacent delivery pipes 1 5 are connected through a tee pipe A7, the tee pipe A7 is connected to the branch pipe 1 8, the water main pipe 2 3 is connected to a plurality of delivery pipes 2 6, a plurality of delivery pipes 2 6 are provided, adjacent delivery pipes 2 6 are connected through a tee pipe B10, and the tee pipe B10 is connected to the branch pipe 2 9.

[0035] The cooling assembly includes a side panel 13, a top panel 14 and a bottom panel 15. The branch pipe 1 8 and the branch pipe 2 9 are both connected to the bottom panel 15. The bottom panel 15 is connected to the side panel 13, and the side panel 13 is connected to the top panel 14. A plurality of side panels 13, a plurality of top panels 14 and a plurality of bottom panels 15 form a closed box. An immersion liquid is provided inside the box. The side panel 13 is preferably welded from multiple panels, and the welds between the side panels 13 are preferably provided on the outside of the box. The cooling unit 1 is a common liquid cooling device for cooling liquid. The cooling device is preferably an air-cooled type cooling unit, which has a component for cooling the liquid and a water pump that drives the cooling liquid to flow and provides pressure, so that the water outlet and the water inlet can circulate the cooling liquid. The cooling liquid is preferably one of water, ethylene glycol solution and fluorinated liquid. The immersion liquid is preferably heat transfer oil or fluorinated liquid, such as synthetic oil and silicone oil. It is preferred that only the immersion liquid, the components to be cooled and the connectors for installing the components to be cooled are stored in the box body, and no other structure is added, so that the immersion liquid can be fully cooled and cooled. The cooling components are in contact, and the refrigeration liquid is cooled by the cooling unit 1, and is transmitted to the inside of the bottom plate 15 through the water main pipe 2, the delivery pipe 5, the tee pipe A7 and the branch pipe 8, and is transmitted back to the cooling unit 1 through the branch pipe 2 9, the tee pipe B10, the delivery pipe 2 6 and the water main pipe 2 3, so that the cooled liquid can circulate inside the bottom plate 15 to cool the modules contained in the box body, and an immersion liquid is arranged inside the box body, so that the inside of the box body is filled with heat-conducting liquid, so that the heat can be evenly distributed inside the box body, the heat dissipation effect is improved, the stored components to be cooled can be quickly cooled, and the cooling performance inside the box body is improved. The way of immersing the module has a better effect of uniform cooling around the components to be cooled. The tee pipe A7 and the tee pipe B10 are arranged, multiple tee pipes A7 connect multiple delivery pipes 1 5 in series, and multiple tee pipes B10 connect delivery pipe 2 6 in series. According to the height of the cooling component, the coolant can be transmitted to different positions, adapted to different transmission application environments, and the adaptability of the coolant transmission place is improved.

[0036] Reference Fig. 9 The cooling assembly also includes a reinforcement partition 16. A plurality of reinforcement partitions 16 are connected to the inside of the bottom plate 15. A gap is set between the reinforcement partition 16 and the top plate 14. By setting the reinforcement partition 16, the supporting effect inside the bottom plate 15 is enhanced, the strength of the bottom plate 15 is improved, and the reinforcement partition 16 separates some areas, which is conducive to the transmission of coolant inside the bottom plate 15.

[0037] Reference Figure 1 The refrigeration component also includes a valve 4. The free ends of the water main pipe 2 and the water main pipe 3 are both equipped with a valve 4. Through the setting of the valve 4, when the transmitted coolant is blocked, the valve 4 is opened, which is conducive to clearing the water main pipe 2 and the water main pipe 3 to transmit the coolant.

[0038] Reference Figure 5The cooling assembly also includes a convex pipe 17. The bottom plate 15 is connected to a plurality of convex pipes 17. The branch pipe 1 8 and the branch pipe 2 9 are connected to the corresponding convex pipes 17. Through the arrangement of the convex pipe 17, the branch pipe 1 8 and the branch pipe 2 9 are more conveniently connected to the bottom plate 15, making it easier to disassemble and assemble the liquid transmission part, which is conducive to maintenance.

[0039] Reference Figure 1 and 2 The refrigeration component also includes valve two 11 and valve three 12. Valve two 11 is installed at the connection between delivery pipe two 6 and water main pipe two 3, and valve three 12 is installed at the connection between water main pipe one 2 and delivery pipe one 5. The setting of valve two 11 and valve three 12 is conducive to controlling the transmission of coolant at delivery pipe one 5 and delivery pipe two 6, which facilitates the cooling of the coolant.

[0040] Reference Figure 1 , 3 and 4, the branch pipe 1 8 and the branch pipe 2 9 are located on both sides of the bottom plate 15, and the cooling liquid is transmitted through the two sides, which is conducive to the circulation of the transmitted cooling liquid inside the bottom plate 15.

[0041] The bottom plate 15 and the side panel 13 are connected by full welding, and the side panel 13 and the top plate 14 are connected by full welding. The full welding can improve the sealing effect and reduce the leakage of liquid from the connection.

[0042] As another application form, the side panel 13 and the top panel 14 are connected by multiple screws. The multiple screw connections facilitate the disassembly and assembly of the connection. The provision of multiple screws facilitates the disassembly and assembly of the connection.

[0043] Reference Figure 1 , wherein the free end of the uppermost delivery pipe 1 5 and the free end of the uppermost delivery pipe 2 6 are both connected with a plug 18. The setting of the plug 18 is conducive to blocking the free end of the uppermost delivery pipe 1 5 and the free end of the uppermost delivery pipe 2 6, so that the coolant transmitted inside the delivery pipe 1 5 and the delivery pipe 2 6 can maintain a certain pressure, which is conducive to the circulation of the liquid and reduces the leakage of the liquid from the delivery pipe 1 5 and the delivery pipe 2 6. The plug 18 can block the free end of the uppermost delivery pipe 1 5 and the free end of the uppermost delivery pipe 2 6. The delivery pipe 1 5 and the delivery pipe 2 6 are preferably connected to the plug 18 by threads, and the threaded connection is preferably provided with a sealing tape.

[0045] Preferably, there are multiple boxes in the same longitudinal direction. It is more convenient to transmit the cooling medium.
