[0022] like Figure 1 As shown, a plurality of heat-conducting silicone gaskets 11 are equidistantly installed on the inner wall of the liquid cooling tube 10. By providing the heat-conducting silicone gaskets 11, the heat of the battery can be absorbed more quickly.

[0023] like Figure 2 , 3, 4, and 5, the positioning assembly 2 includes a plurality of guide columns 202 and a plurality of fixing holes 206, wherein the plurality of guide columns 202 are fixedly mounted on both sides of the housing 1, and the plurality of fixing holes 206 are respectively provided on both sides of the mounting frame 8, a guide plate 201 is slidably mounted in the middle of the guide column 202, a plurality of fixing columns 205 are evenly and equidistantly fixedly mounted on the surface of the guide plate 201, the top of the fixing column 205 movably passes through the mounting groove 12 and is arranged inside the fixing hole 206, a plurality of guide columns 202 are provided with threads 203 on the side surfaces, a threaded sleeve 204 is meshedly mounted in the middle of the threaded sleeve 204, and the threaded sleeve 204 is arranged on the upper surface of the guide plate 201, and the threaded sleeve 204 is arranged on the upper surface of the guide plate 201, and the threaded sleeve 204 is arranged on the upper surface of the guide plate 201 by the staff rotating the screw. The threaded sleeve 204 is used to move the threaded sleeve 204 on the thread 203, so that the threaded sleeve 204 moves upward in the middle of the guide column 202. At this time, the threaded sleeve 204 will not press on the upper surface of the guide plate 201, so that the guide plate 201 moves upward on the guide column 202, which can make the fixed column 205 move away from the shell 1, so that the fixed column 205 is disengaged from the fixing hole 206.

[0024] The working principle of a lithium battery shell with a heat dissipation structure:

[0025] When in use, placing the lithium battery between the inner walls of the liquid cooling tube 10 can protect the lithium battery. When the lithium battery needs to dissipate heat, the radiator 4 is filled with coolant. At this time, the water pump 5 works to pump the coolant inside the radiator into the liquid cooling tube 10. The coolant flows inside the liquid cooling tube 10. Because the lithium battery is placed inside the liquid cooling tube 10, the coolant will absorb the heat dissipated by the lithium battery. The coolant will continue to flow forward due to the pressure and flow into the radiator 4. The radiator 4 can cool the coolant with a higher temperature, and circulate it after cooling is completed to dissipate heat for the lithium battery. In addition, by installing a dustproof net 9 on the other side of the shell 1, the air inside the shell 1 can flow, thereby improving the cooling efficiency.

At this time, the threaded sleeve 204 will not press on the upper surface of the guide plate 201, so that the guide plate 201 moves upward on the guide column 202, so that the fixing column 205 can be moved in the direction away from the shell 1, so that the fixing column 205 is disengaged from the fixing hole 206. At this time, the mounting frame 8 is not constrained in the mounting groove 12, and the mounting frame 8 can be disengaged from the mounting groove 12. Otherwise, the mounting frame 8 can be installed in the mounting groove 12. This device can facilitate the disassembly and installation of the dust screen 9, and is convenient for the staff to clean and replace the dust screen 9.
