DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0021] Reference is made to Figures 1-6 ​The utility model provides a kind of high-efficiency solid-state battery module liquid cooling device, including solid-state battery module body 1, liquid cooling plate assembly 2 is fixedly arranged at the top of solid-state battery module body 1, liquid cooling pipe 3 is arranged in the inside of liquid cooling plate assembly 2, both ends of liquid cooling pipe 3 are from liquid cooling plate assembly 2 and are connected with connecting pipe 4.The rotating ring 42 is arranged on connecting pipe 4, the inner wall of rotating ring 42 is provided with internal thread 43, the end of liquid cooling pipe 3 is adapted to open outer screw groove 33 corresponding to internal thread 43, and the end of liquid cooling pipe 3 is movably provided with a plurality of limiting columns 311, and the rotating ring 42 is adapted to open limiting cavity 421 corresponding to limiting column 311.

[0022] Wherein, the end of liquid cooling pipe 3 is provided with a plurality of springs 32 outward, and the other end of spring 32 is connected with movable ring 31. By the setting of spring 32, movable ring 31 can be pushed outward, so that limiting column 311 can be stably clamped in limiting cavity 421.

[0023] Wherein, limiting column 311 is fixedly installed on movable ring 31, and limiting column 311 is arranged around the center of movable ring 31. When rotating ring 42 is completely rotated and set on outer screw groove 33, limiting column 311 is aligned with limiting cavity 421.

[0024] Wherein, the outer wall of connecting pipe 4 is fixedly provided with fixed ring 41, and rotating ring 42 is located in fixed ring 41 and rotates. A plurality of anti-falling rings 411 are fixedly arranged on the inner wall of fixed ring 41, and corresponding anti-falling rings 411 are adapted to be provided with anti-falling cavities 422 on the outer wall of rotating ring 42. By the adaptive setting between anti-falling ring 411 and anti-falling cavity 422, rotating ring 42 can rotate on the inside of fixed ring 41, and rotating ring 42 can be prevented from falling out of fixed ring 41.

[0025] In the embodiment, liquid cooling plate assembly 2 is installed on the top of solid-state battery module body 1, liquid cooling pipe 3 is arranged in the inside of liquid cooling plate assembly 2, both ends of liquid cooling pipe 3 are from liquid cooling plate assembly 2 and are connected with the pipe of external refrigeration mechanism through connecting pipe 4. The cooling liquid circulation is realized, and the heat exchange cooling of solid-state battery module body 1 is realized. It is worth noting that the specific heat exchange channel of liquid cooling plate assembly 2 and its cooling structure are prior art, and do not belong to the technical problem of facilitating the replacement of connecting pipe 4 required to be solved in the technical scheme, so no more is described.

[0026] Further, when the user needs to install connecting pipe 4 on the end of liquid cooling pipe 3, only need to align internal thread 43 on rotating ring 42 and outer screw groove 33 on liquid cooling pipe 3. Then rotating ring 42 is rotated, so that internal thread 43 and outer screw groove 33 are engaged together.

[0027] Then the user only needs to push the movable ring 31 to the opposite direction of the rotating ring 42 to compress the spring 32. Then continue to rotate the rotating ring 42, when the rotating ring 42 is completely rotated to the outer screw groove 33, the limiting cavity 421 on the rotating ring 42 and the limiting column 311 on the movable ring 31 are matched and aligned. At this time, the user only needs to release the movable ring 31, and the movable ring 31 can be automatically reset by the elastic force of the spring 32, so as to drive the limiting column 311 to be clamped into the limiting cavity 421. In this way, the locking of the rotating ring 42 can be realized by the mutual clamping between the limiting column 311 and the limiting cavity 421, so as to improve the connection effect between the liquid cooling pipeline 3 and the connecting pipe 4.

[0028] Further, when the user needs to remove the connecting pipe 4, the movable ring 31 is pulled again, so that the mutual clamping between the limiting column 311 and the limiting cavity 421 is released. Then the user can rotate the rotating ring 42 in the opposite direction to release the mutual engagement between the inner thread 43 and the outer screw groove 33, so as to realize the removal of the connecting pipe 4.

[0029] Further, since the inner thread 43 and the outer screw groove 33 are matched with each other, when the rotating ring 42 is completely rotated to the outer screw groove 33, the limiting cavity 421 on the rotating ring 42 and the limiting column 311 on the movable ring 31 can be matched and aligned.

[0030] Further, the connecting pipe 4 is provided with a plurality of different specifications, but the connecting pipe 4 of different specifications is provided with the fixed ring 41, the rotating ring 42 and the inner thread 43 matched with the liquid cooling pipeline 3. This makes the user can install the connecting pipe 4 of different sizes on the liquid cooling pipeline 3, and through the modular design, the flexibility of the device can be improved.

[0031] Further, the inner wall of the movable ring 31 is provided with a limiting piece, and the outer wall of the liquid cooling pipeline 3 is provided with a limiting groove matched with the limiting piece. Through the matched arrangement between the limiting piece and the limiting groove, the stability of the movable ring 31 during the movement can be improved.

[0032] In the utility model, through the liquid cooling plate assembly 2, the heat exchange and cooling of the solid-state battery module body 1 can be realized, through the matched engagement between the inner thread 43 and the outer screw groove 33, and the locking between the limiting column 311 and the limiting cavity 421, the connecting pipe 4 can be stably installed on the liquid cooling pipeline 3, through the modular design, the flexibility of the device can be improved, so that the user can replace the connecting pipe 4 of different specifications according to the pipeline of different sizes of refrigeration equipment, so as to improve the assembly efficiency.
