[0032] Furthermore, the cold liquid enters the liquid cooling inlet pipe 6 through the liquid cooling host 4 and the high-pressure box 5, and then enters the battery pack 3. The cold liquid flows out of the battery pack 3 through the liquid cooling outlet pipe 7, and the liquid cooling outlet pipe 7 flows back to the liquid cooling host 4.

[0033] More specifically, the present invention also includes a flow regulating assembly 8, wherein the flow regulating assembly 8 includes a flow regulating box 8.1, a diverter baffle 8.2, a first liquid cooling port 8.3, a second liquid cooling port 8.4, an adjusting groove 8.5, a diverter regulating plate 8.6, a first liquid cooling sub-tube 8.7, a second liquid cooling sub-tube 8.8, an expansion cylinder 8.9, a connecting pipe 8.10, an expansion and telescopic rod 8.11 and a connecting plate 8.12. The flow regulating box 8.1 is fixedly mounted on the battery pack 3, the diverter baffle 8.2 is fixedly mounted inside the flow regulating box 8.1, the first liquid cooling port 8.3 is provided on the diverter baffle 8.2, the second liquid cooling port 8.4 is provided on the diverter baffle 8.2, and the adjusting groove 8.5 is provided on the diverter baffle. Inside 8.2, a diverter adjustment plate 8.6 is slidably mounted inside diverter baffle 8.2. Diverter adjustment plate 8.6 is located within adjustment slot 8.5. The sliding of diverter adjustment plate 8.6 within diverter baffle 8.2 is used to control the opening sizes of the first liquid cooling port 8.3 and the second liquid cooling port 8.4. A first liquid cooling sub-tube 8.7 is fixedly mounted on diverter baffle 8.2, with the end of the first liquid cooling sub-tube 8.7 facing the first liquid cooling port 8.3. A second liquid cooling sub-tube 8.8 is mounted on diverter baffle 8.2, with the end of the second liquid cooling sub-tube 8.8 facing the second liquid cooling port 8.4. The flow regulating assembly 8 is used to automatically adjust the flow rate of the coolant for the corresponding battery pack 3.

[0034] One end of an expansion cylinder 8.9 is fixedly mounted on the flow regulating box 8.1. The expansion cylinder 8.9 contains mercury liquid. The other end of the expansion cylinder 8.9 extends into the battery pack 3. One end of a connecting tube 8.10 is fixedly mounted on the expansion cylinder 8.9. The other end of the connecting tube 8.10 is fixedly mounted on the expansion cylinder 8.9. The expansion cylinder 8.9 is connected to the connecting tube 8.10 and the expansion cylinder 8.11. The expansion cylinder 8.9 is connected to the connecting tube 8.10 and the expansion cylinder 8.11. The expansion cylinder 8.9 is connected to the connecting tube 8.10 and the expansion cylinder 8.11.

[0035] The end of the first liquid cooling sub-tube 8.7 away from the diverter baffle 8.2 extends into the battery pack 3, the second liquid cooling sub-tube 8.8, the telescopic end of the expansion and telescopic rod 8.11 extends to the end of the second liquid cooling sub-tube 8.8 away from the diverter baffle 8.2 and extends into the liquid cooling inlet pipe 6, and the connecting plate 8.12 is located in the second liquid cooling sub-tube 8.8.

[0036] Furthermore, the coolant enters the flow regulating box 8.1 from the liquid cooling inlet pipe 6, and the coolant is then diverted from the first liquid cooling port 8.3 and the second liquid cooling port 8.4 of the diverter baffle 8.2. The diverter adjustment plate 8.6 slides in the adjustment groove 8.5 of the diverter baffle 8.2 to control the opening size of the first liquid cooling port 8.3 and the second liquid cooling port 8.4. When the diverter adjustment plate 8.6 moves toward the first liquid cooling port 8.3, the first liquid cooling port 8.3 gradually becomes smaller and the second liquid cooling port 8.4 gradually becomes larger; when the diverter adjustment plate 8.6 moves toward the second liquid cooling port 8.4, the first liquid cooling port 8.3 gradually becomes larger and the second liquid cooling port 8.4 gradually becomes smaller.

[0037] The expansion cylinder 8.9 is affected by the temperature of the battery pack 3, causing the mercury liquid inside the expansion cylinder 8.9 to overflow and enter the connecting tube 8.10 and the expansion and telescopic rod 8.11. The overflowing mercury liquid pushes out the telescopic end of the expansion and telescopic rod 8.11, which drives the diverter adjustment plate 8.6 to move. The higher the temperature inside the battery pack 3, the greater the distance the diverter adjustment plate 8.6 moves. The second liquid cooling port 8.4 is gradually blocked by the diverter adjustment plate 8.6 until it is completely closed. At this time, the first liquid cooling port 8.3 is fully open, and the other end of the diverter adjustment plate 8.6 no longer blocks the first liquid cooling port 8.3.

[0038] The expansion cylinder 8.9 is affected by the temperature inside the battery pack 3. When the temperature is high, more mercury liquid overflows from the expansion cylinder 8.9, and the telescopic end of the expansion and telescopic rod 8.11 drives the diverter adjustment plate 8.6 to move a larger distance. The expansion cylinder 8.9 is affected by the temperature inside the battery pack 3. When the temperature is low, the mercury liquid inside the expansion cylinder 8.9 retracts, and the expansion and telescopic rod 8.11 is affected by the negative pressure inside the expansion cylinder 8.9, causing the telescopic end of the expansion and telescopic rod 8.11 to retract, and the telescopic end of the expansion and telescopic rod 8.11 drives the diverter adjustment plate 8.6 to move a smaller distance.

[0039] The cooling liquid of the first cooling port 8.3 flows from the first cooling sub-pipe 8.7 into the battery pack 3, and the cooling liquid of the second cooling port 8.4 flows from the second cooling sub-pipe 8.8 back into the cooling inlet pipe 6.

[0040] More specifically, the battery pack 3 also includes a water inlet plate 3.3, a liquid cooling plate 3.4, a water outlet plate 3.5 and a liquid return plate 3.6, wherein the water inlet plate 3.3 is installed in the battery pack 3, the liquid cooling plate 3.4 is installed in the battery pack 3, and the water outlet plate 3.5 is installed in the battery pack 3. The water inlet plate 3.3 is fixedly installed on the top of the liquid cooling plate 3.4, and the water outlet plate 3.5 is fixedly installed on the side of the liquid cooling plate 3.4 away from the water inlet plate 3.3, and the water inlet plate 3.3 is parallel to the water outlet plate 3.5. One end of the liquid return plate 3.6 is fixedly installed on the water outlet plate 3.5, and the other end of the liquid return plate 3.6 is installed on the liquid cooling outlet pipe 7. The liquid return plate 3.6 is located on the inner wall of the battery pack 3 away from the expansion cylinder 8.9.

[0041] A water transfer cavity 3.3.1 is defined within the water inlet plate 3.3, a diversion hole 3.3.2 is defined on the outer surface of the water inlet plate 3.3, a connection hole 3.4.1 is defined on the outer surface of the liquid cooling plate 3.4, a liquid cooling collection cavity 3.4.2 is defined within the liquid cooling plate 3.4, a liquid cooling diversion cavity 3.4.3 is defined within the liquid cooling plate 3.4, a side cooling plate 3.4.4 is provided within the liquid cooling plate 3.4, a curved cooling groove 3.4.5 is defined within the side cooling plate 3.4.4, a water outlet cavity 3.5.1 is defined within the water outlet plate 3.5, and a return hole 3.5.2 is defined on the outer surface of the water outlet plate 3.5.

[0042] Furthermore, the first liquid cooling sub-pipe 8.7 flows into the battery pack 3, then enters the water inlet plate 3.3, the liquid cooling plate 3.4, the water outlet plate 3.5 and the liquid return plate 3.6, and then flows back to the liquid cooling host 4 through the liquid cooling outlet pipe 7.

[0043] The cold liquid enters the water delivery cavity 3.3.1 of the water inlet plate 3.3. The cold liquid in the water delivery cavity 3.3.1 enters the liquid cooling plate 3.4 through the diversion hole 3.3.2. After the cold liquid flows into the liquid collecting cold cavity 3.4.2, it is diverted to the liquid diversion cold cavity 3.4.3. Part of the cold liquid in the liquid diversion cold cavity 3.4.3 enters the side cold plate 3.4.4. The cold liquid in the side cold plate 3.4.4 returns to the liquid diversion cold cavity 3.4.3 from the other end. The cold liquid in the liquid diversion cold cavity 3.4.3 enters the water outlet plate 3.5, and then enters the liquid return plate 3.6 from the water outlet plate 3.5. The cold liquid then enters the liquid cooling outlet pipe 7 from the liquid return plate 3.6, and the cold liquid flows back to the liquid cooling host 4 through the liquid cooling outlet pipe 7.
