As the key to ensuring the safe and stable operation of lithium battery systems, thermal management systems are being paid attention to by more and more practitioners. Thermal management technology has also been upgraded from early air cooling solutions to liquid cooling systems with higher heat dissipation efficiency and better temperature balancing. The liquid cooling unit has built-in refrigeration circuits, coolant circuits and fans. The refrigeration circuit cools the coolant circuit through a plate heat exchanger, and the fan is used to dissipate heat from the condenser on the refrigeration circuit.

[0024] The following is combined with Figure 1 -Attached Figure 3 This application is described in further detail.

[0025] The present application embodiment discloses a liquid cooling device for an energy storage system. Figure 1-Figure 3 A liquid cooling device for an energy storage system comprises a liquid cooling device body 1, air inlets 2 are provided on both sides of the liquid cooling device body 1, an air outlet 3 is provided on the other side, a detachable filter screen 5 is installed on the air inlet 2 and the air outlet 3, and a heat dissipation fan 4 is fixed near the air outlet 3 inside the liquid cooling device body 1;

[0026] A fixing box 12 is fixed on both sides of the two air inlets 2 and both sides of the air outlet 3, and a avoidance groove 10 is opened on one side of the three pairs of fixing boxes 12. A moving piece 13 is placed inside the fixing box 12, and a spring 14 is fixed on one side of the moving piece 13. The spring 14 is located between the moving piece 13 and the inner wall of the fixing box 12. Two cylinders 16 are also placed inside the fixing box 12 near the avoidance groove 10. A fixing plate 17 is fixed on both sides of the three filter screens 5, and a plug rod 7 is fixed on one side of the fixing plate 17. The outer wall of the plug rod 7 is provided with two stop grooves 8 for the cylinder 16 to be embedded, and two inclined surfaces are also provided at one end of the plug rod 7. The three pairs of rods 7 all penetrate the liquid cooling device body 1 and the avoidance groove 10 and are located inside the fixed box 12; when in use, first, place the filter 5 on the air inlet 2 or the air outlet 3, and insert the rod 7 into the interior of the fixed box 12. At this time, since one end of the rod 7 is provided with an inclined groove 9, it can pass between the two cylinders 16. At this time, the cylinder 16 will rotate and move slightly, and push the moving piece 13 to move, so that it squeezes the spring 14 and contracts the spring 14. When the rod 7 is inserted into the interior of the fixed box 12, the stop groove 8 will contact the cylinder 16. At this time, the spring 14 will push the moving piece 13 to move. The movable sheet 13 resets the two cylinders 16 and moves them to the inside of the stop groove 8. Through the reset effect of the spring 14, the cylinder 16 on the movable sheet 13 is embedded in the stop groove 8, thereby fixing the filter 5. When the filter 5 needs to be cleaned or replaced, the operator can manually pull the filter 5 outward to move the plug rod 7 inside the fixing box 12. When the plug rod 7 is moving, it will compress the spring 14 and push the movable sheet 13 to move, so that the cylinder 16 on the movable sheet 13 is disengaged from the stop groove 8, thereby releasing the lock of the plug rod 7. At this time, the filter 5 can be removed from the air inlet 2 or the air outlet. 3, for cleaning or replacement. The liquid cooling device in the embodiment of the present application realizes the rapid disassembly and installation of the filter 5 by setting a detachable filter 5 and using the fixing box 12, the movable sheet 13, the spring 14 and the cylinder 16 and other components, thereby facilitating the cleaning and replacement of the filter 5 and improving the maintenance efficiency of the liquid cooling device. In addition, in order to improve the heat dissipation performance of the liquid cooling device body 1, the embodiment of the present application also fixes the heat dissipation fan 4 at a position near the air outlet 3 inside the liquid cooling device body 1. The setting of the heat dissipation fan 4 can speed up the air circulation inside the liquid cooling device body 1, thereby improving the heat dissipation effect. At the same time, in order to prevent the heat dissipation fan 4 from inhaling dust and impurities during operation and affecting its normal operation, the embodiment of the present application also sets a filter 5 on the outside of the heat dissipation fan 4, further improving the stability and reliability of the liquid cooling device.

[0027] Reference Figure 3Two guide rods 15 are fixed on one side of the moving piece 13, and the two guide rods 15 both penetrate the fixed box 12; this can increase the stability of the moving piece 13 when moving, so that it is not easy to shake.

[0028] Reference Figure 3 The sum of the length of the guide rod 15 and the diameter of the cylinder 16 is greater than the length of the fixed box 12; when the spring 14 pushes the movable sheet 13 to reset, the guide rod 15 can be prevented from moving into the interior of the fixed box 12, thereby preventing it from falling off.

[0029] Reference Figure 3 , both sides of the two air inlets 2 and the air outlet 3 are provided with placement grooves 11 for the fixing plate 17 to be embedded in; further increasing the stability of the filter screen 5 and making it less likely to shake.

[0030] Reference Figure 3 The material of the insert rod 7 is metal; it is not easy to break or bend, and its service life is extended.

[0031] Reference Figure 1 and Figure 2 A pull rod 6 is fixed on one side of the filter screen 5 , and an anti-slip sleeve is provided on the outer wall of the pull rod 6 , and the material of the anti-slip sleeve is rubber material; it is convenient for users to pull or push the filter screen 5 .

[0032] Reference Figure 3 when the rod 7 is inserted into the interior of the fixed box 12, one end of the rod 7 can be avoided from abutting against the interior of the fixed box 12, thereby avoiding friction between the rod 7 and the fixed box 12.

[0033] The implementation principle of the liquid cooling device of an energy storage system in the embodiment of the present application is as follows: when installing the filter 5, the filter 5 is first placed on the air inlet 2 or the air outlet 3, and the insertion rod 7 is inserted into the interior of the fixing box 12. At this time, since one end of the insertion rod 7 is provided with an inclined slide groove 9, it can pass through between the two cylinders 16. At this time, the cylinder 16 will rotate and move slightly, and push the moving sheet 13 to move, so that it squeezes the spring 14 and contracts the spring 14. When the insertion rod 7 is inserted into the interior of the fixing box 12, the stop groove 8 will contact the cylinder 16. At this time, the spring 14 will push the moving sheet 13 to reset the two cylinders 16 and move them to the interior of the stop groove 8. Through the reset action of the spring 14, the cylinder 16 on the moving sheet 13 is embedded in the stop groove 8, thereby achieving the fixation of the filter 5.

[0034] When the filter 5 needs to be cleaned or replaced, the operator can manually pull the filter 5 outward to move the rod 7 inside the fixed box 12. When the rod 7 moves, the spring 14 is compressed and the movable sheet 13 is pushed to move, so that the cylinder 16 on the movable sheet 13 is disengaged from the stop groove 8, thereby releasing the lock on the rod 7. At this time, the filter 5 can be removed from the air inlet 2 or the air outlet 3 for cleaning or replacement. The liquid cooling device in the embodiment of the present application realizes the rapid disassembly and installation of the filter 5 by providing a detachable filter 5 and using components such as the fixed box 12, the movable sheet 13, the spring 14 and the cylinder 16, thereby facilitating the cleaning and replacement of the filter 5 and improving the maintenance efficiency of the liquid cooling device.
