[0030] Example 1

[0031] The present invention provides an immersion type liquid cooling energy storage cabinet which is easy to maintain. Figure 1-3As shown, it includes: an integrated welded box body 1, the bottom of the inner wall of the integrated welded box body 1 is set as a hollow flow channel 8 structure, and the positioning plate 10 is installed on the bottom of the integrated welded box body 1 by bolts, and a plurality of groups of module positioning components 9 are arranged around the positioning plate 10, and the battery cell 2 is installed in the integrated welded box body 1 through the module positioning components 9, and the upper cover 4 is installed on the top of the integrated welded box body 1 by a plurality of groups of screws 5.

[0032] Preferably, a liquid outlet 6 and a liquid inlet 7 are provided on the outer wall of the integrally welded box body 1 .

[0033] Preferably, a sealing ring 3 is provided between the upper cover 4 and the top of the integrated welded box body 1 .

[0034] Preferably, a gap for the coolant to flow is left between the positioning plate 10 and the inner wall of the integrally welded box body 1 .

[0035] Preferably, a plurality of groups of threaded holes 11 and guide holes 12 are formed on the positioning plate 10 .

[0036] The working principle and beneficial effects of the above technical solution are as follows: after the battery cell 2 is placed into the integrated welded box body 1 and fixed by the module positioning assembly 9, the upper cover 4 is snap-fitted and installed on the top of the integrated welded box body 1 by a number of screws 5 to complete the sealing of the battery cell 2. The coolant enters the integrated welded box body 1 through the liquid inlet 7 and can be discharged through the liquid inlet 7, which can cool the battery cell 2, extend the life of the battery cell 2, and reduce the energy storage cost.

[0037] Among them, the integrated welded box body 1 is welded by aluminum profiles to achieve effective sealing. The bottom of the inner wall of the integrated welded box body 1 is made into a hollow flow channel 8 structure. The coolant enters the bottom of the box body from the liquid inlet 7 at the bottom of the inner wall of the integrated welded box body 1. The liquid inlet 7 at the bottom can be finely designed to ensure that the flow rate of the coolant for each battery cell 2 in the box body remains uniform, thereby ensuring that the temperature difference of the battery cell 2 is close to zero degrees;

[0038] The finely designed internal structure of the utility model improves the heat dissipation efficiency, reduces the temperature difference, prolongs the life of the battery cell 2, and reduces the energy storage cost. The setting of the module positioning component 9 can limit and fix the battery cell 2 to prevent the battery cell 2 from being damaged due to shaking. In addition, the utility model adopts immersion liquid cooling technology, which improves the charging and discharging rate and expands the application field of energy storage.

[0039] Example 2

[0040] Based on Example 1, please refer to Figure 4-8The module positioning assembly 9 includes: an L-shaped support frame 13 and an L-shaped limiter 18. The L-shaped support frame 13 is installed on the frame of the positioning plate 10 by bolts. A rotating shaft 16 is fixed to the top of the vertical section of the L-shaped support frame 13. A rotating sleeve 17 is movably sleeved on the outer wall of the rotating shaft 16, and the rotating sleeve 17 is fixed to the back of the push plate 15.

[0041] Preferably, a guide slot 14 is provided in the middle of the horizontal section of the L-shaped support frame 13 , a guide block 23 is movably disposed in the guide slot 14 , and a right-angle end at the back of the L-shaped limiter 18 is movably connected to the guide block 23 .

[0042] Preferably, the U-shaped end of the U-shaped pad 20 is a hollow structure, and the horizontal section of the L-shaped limiter 18 movably extends into the U-shaped end of the U-shaped pad 20 and is movably connected to the inner wall of the U-shaped end of the U-shaped pad 20 through the rotating shaft 2 19.

[0043] Preferably, two groups of piston sleeves 22 are symmetrically fixed on the back of the L-shaped limit member 18, and springs are installed in the piston sleeves 22. One end of the two groups of piston rods 21 is fixedly connected to the back of the push plate 15, and the other ends of the two groups of piston rods 21 are movably extended into the two groups of piston sleeves 22 and connected to the springs in the piston sleeves 22.

[0044] Preferably, a rectangular groove 24 is formed at the front end of the L-shaped limiting member 18 , and a buffer airbag is provided in the rectangular groove 24 .

[0045] The working principle and beneficial effects of the above technical solution are as follows: when in use, after the battery cell 2 is moved to the top of the positioning plate 10 and aligned, the battery cell 2 is put down, and the battery cell 2 will first contact with the U-shaped pad 20 and press down, so that the horizontal end of the L-shaped limiter 18 rotates around the U-shaped pad 20, and the U-shaped pad 20 can push the L-shaped limiter 18 to slide along the guide groove 14, so that the L-shaped limiter 18 and the U-shaped pad 20 move toward a state parallel to the horizontal section of the L-shaped support frame 13, and at the same time When the push plate 15 is in a vertical position and in contact with the outer wall of the battery cell 2, the battery cell 2 is fixed, thereby realizing rapid positioning of the battery cell 2 and preventing the battery cell 2 from shaking. In the above manner, the battery cell 2 can be limited and fixed, thereby preventing the battery cell 2 from being damaged due to shaking.

[0046] The provision of the airbag in the rectangular groove 24 can protect the battery cell 2, the provision of several groups of guide holes 12 on the positioning plate 10, and the gap between the positioning plate 10 and the inner wall of the integral welded box body 1 can facilitate the flow of the coolant.
