[0024] The following combination Figure 1-2 The present invention provides a liquid cooling system for a liquid cooling unit. Figure 1 It is a structural diagram of the liquid cooling pipeline system. Figure 2 It is a structural schematic diagram of the liquid inlet pipeline 1, the three-way pipeline 2 and the liquid replenishment pipeline 3 of the liquid cooling pipeline system in a disassembled state.

[0025] The present application provides a liquid cooling pipeline system of a liquid cooling unit, which is used to cool and heat energy storage components such as battery packs to ensure that they work within an optimal temperature range, thereby improving the life and safety of the battery pack. The cooling medium flowing in the liquid cooling pipeline can be antifreeze or water.

[0026] Specifically, the liquid cooling pipeline system includes a liquid inlet pipeline 1, a three-way pipeline 2 and a liquid replenishing pipeline 3 which are separately arranged. The liquid outlet of the liquid inlet pipeline 1 is connected to the liquid inlet of the three-way pipeline 2 through a first clamp assembly 41, and a filter 11 is provided on the liquid inlet pipeline 1; the first liquid outlet of the three-way pipeline 2 is connected to the liquid replenishing pipeline 3 through a second clamp assembly 42, and the second liquid outlet of the three-way pipeline 2 is used to communicate with the expansion tank 8.

[0027] Specifically, the distance from the filter 11 to the first clamp assembly 41 is greater than or equal to 60 mm. In some possible embodiments, the distance from the filter 11 to the first clamp assembly 41 is 60-150 mm. Preferably, the distance from the filter 11 to the first clamp assembly 41 can be 80 mm, 90 mm, 100 mm, 110 mm, 120 mm, 140 mm or 150 mm. The distance setting between the filter and the first clamp assembly 41 can avoid interference between the filter 11 and the first clamp assembly 41 during disassembly and assembly, ensure the stability of the connection, facilitate the disassembly and assembly of the filter 11 and the first clamp assembly 41, and facilitate maintenance and replacement. When the present application performs maintenance and replacement on the filter 11, it is only necessary to disassemble the liquid inlet pipeline 1 at the first clamp assembly 41, which is simple and convenient, and the replacement cost is low.

[0028] Specifically, a refill valve 31 is provided on the refill pipeline 3, which is used to control the refilling of the liquid cooling pipeline system and ensure the sealing of the system. In the embodiment of the present application, the refill valve 31 is arranged near the liquid outlet of the refill pipeline 3. When the refill valve 31 needs to be maintained and replaced, the refill pipeline 3 only needs to be disassembled at the second clamp assembly 42, which is simple and convenient, and the replacement cost is low. In some possible embodiments, it can be determined whether the liquid cooling pipeline system needs to be refilled according to the monitoring conditions of the pressure, temperature, flow rate, etc. of the liquid cooling pipeline system, so as to control the refill valve to refill and realize precise control of the liquid cooling pipeline system. Specifically, in the embodiment of the present application, a tee 32 and a refill branch pipeline 33 are provided at the liquid outlet of the refill pipeline 3, and the liquid outlet of the refill pipeline 3 and the refill branch pipeline 33 are respectively connected to the tee 32, and the refill valve 31 is arranged on the refill branch pipeline 33. The refill valve 31 is arranged on the refill branch pipeline 33, so that the refill operation is more flexible, and it is convenient for the maintenance and replacement of the refill valve 31, and it is also convenient to choose whether to refill according to needs.

[0029] Specifically, the three-way pipeline 2 includes a three-way liquid inlet section 21, a first liquid outlet section 22 and a second liquid outlet section 23 that are connected to each other, and the three-way liquid inlet section 21 is arranged in parallel with the second liquid outlet section 23. In practical applications, the second liquid outlet section 23 bends to one side from the connection point with the three-way pipeline 2, and the height of the second liquid outlet on the second liquid outlet section 23 is close to the height of the liquid inlet on the liquid inlet section 21. In some embodiments, the height of the liquid inlet of the liquid inlet section 21 is higher than the height of the second liquid outlet on the second liquid outlet section 23. The second liquid outlet on the second liquid outlet section 23 is connected to the expansion tank 8, and the second liquid outlet section 23 is arranged in parallel with the liquid inlet section 21, which is conducive to the installation of the expansion tank 8 and the spatial arrangement of the pipelines in the liquid cooling pipeline system, so that the entire liquid cooling pipeline system is compact and practical, and easy to produce and install.

[0030] The expansion tank 8 of the present application can absorb the expansion or contraction of the liquid when the temperature, pressure fluctuation and flow change in the pipeline system, thereby protecting the pipeline and equipment from damage. When the pressure in the pipeline system exceeds the rated pressure of the expansion tank, the expansion tank will automatically expand to absorb the excess pressure; when the pressure in the pipeline system is lower than the rated pressure of the expansion tank, the expansion tank will automatically contract to release the stored liquid and replenish it into the pipeline system, so as to prevent the pressure in the pipeline system from dropping too sharply and reduce the number of times the refill valve is used for refilling.

[0031] Specifically, the first clamp assembly 41 and the second clamp assembly 42 each include a sealing ring and a clamp 401, and the sealing ring is placed on the inner side of the clamp 401. The combined design of the sealing ring and the clamp 401 can effectively ensure the sealing of the two connecting pipelines and prevent liquid leakage. In some possible embodiments, the first clamp assembly 41 and the second clamp assembly 42 can be a groove clamp assembly, the clamp assembly includes a sealing ring, a clamp and a locking bolt, and the two connected pipelines are provided with a groove structure or a flange structure that cooperates with the clamp. Exemplarily, a groove structure is provided at one end of the liquid inlet pipeline 1 near its liquid outlet, and a groove structure is provided at one end of the three-way pipeline 2 near its liquid inlet. The sealing ring is arranged on the outer side of the liquid outlet of the liquid inlet pipeline 1 and the liquid inlet of the three-way pipeline 2, and is consistent with the groove structure on the liquid inlet pipeline 1 and the three-way pipeline 2. The clamp is buckled on the outer side of the sealing ring and then tightened by the locking bolt. In the embodiment of the present application, a flange structure is provided at one end of the liquid inlet pipeline 1 near its liquid outlet, a flange structure is provided at one end of the three-way pipeline 2 near its liquid inlet, a groove structure is provided on the clamp that cooperates with the flange structure, the sealing ring is matched with the groove structure inside the clamp, and the clamp is tightened by a locking bolt. Connecting the pipelines through the clamp assembly has the characteristics of high connection reliability, good sealing, and high overall strength and safety.

[0032] Specifically, a water pump 34 is provided on the liquid replenishment pipeline 3, and the liquid outlet of the liquid replenishment pipeline 3 is connected to the liquid inlet of the water pump 34, and the liquid outlet of the water pump 34 is connected to the liquid inlet of the heat exchanger 5 through a connecting pipeline. The water pump 34 is provided on the liquid replenishment pipeline 3 and connected to the heat exchanger 5 through the connecting pipeline, so that the circulation and forced convection of the liquid in the liquid cooling pipeline system can be realized, which is conducive to improving the heat exchange efficiency and the cooling effect of the liquid cooling pipeline system.

[0033] Specifically, the liquid cooling pipeline system also includes a liquid outlet pipeline 6, which is used to communicate with the liquid outlet of the heat exchanger 5. The liquid inlet pipeline 1, the three-way pipeline 2, the liquid replenishment pipeline 3, the connecting pipeline, the heat exchanger 5, the liquid outlet pipeline 6 and the energy storage element of the present application form a complete liquid circulation loop, ensuring that the cooling liquid can circulate smoothly to cool the energy storage element.

[0034] In some possible implementations, the heat exchanger of the present application may be a plate heat exchanger, which has the characteristics of high heat exchange efficiency, small heat loss, compact and light structure, and long service life.

[0035] Specifically, the liquid inlet pipeline 1 includes a liquid inlet section 12 of the liquid inlet pipe, and the liquid outlet pipeline 6 includes a liquid outlet section 61 of the liquid outlet pipe. A clamping piece 7 is provided on the liquid inlet section 12 of the liquid inlet pipe, and the liquid inlet section 12 of the liquid inlet pipe and the liquid outlet section 61 of the liquid outlet pipe are fixed by the clamping piece 7 and are arranged at intervals. The arrangement of the clamping piece 7 makes the pipe of the liquid cooling pipe system more firmly fixed, reduces vibration and shaking, and improves the stability of the pipe system.

[0036] Specifically, both the liquid inlet pipeline 1 and the liquid outlet pipeline 6 are provided with temperature sensors and water flow sensors, which can monitor the temperature and liquid flow of the liquid cooling pipeline system in real time, and provide data support for the control and optimization of the liquid cooling pipeline system. The temperature sensor can monitor the liquid temperature in the pipeline system in real time. When the liquid temperature is greater than the preset temperature, the energy storage element can be cooled by replenishing the pipeline system or increasing the flow rate through a water pump to increase the heat exchange efficiency. The water flow sensor can monitor the water flow in the pipeline system in real time to accurately control the water flow in the system.

[0037] In some possible implementations, a pressure sensor is further provided on the liquid cooling pipeline system, through which the pressure of the liquid cooling pipeline can be monitored to maintain the pressure of the pipeline stable and to make the coolant pressure inside the pipeline run at a set value.

[0038] The liquid cooling pipeline system of the present application includes a split-design liquid inlet pipeline, a three-way pipeline and a liquid replenishment pipeline. The filter is arranged on the liquid inlet pipeline, and the liquid replenishment valve is arranged on the liquid replenishment pipeline, so that maintenance and replacement of the filter and the liquid replenishment valve only require disassembly of the corresponding liquid inlet pipeline and the liquid replenishment pipeline. The disassembly is simple and convenient, the replacement cost is low, and the replacement cost-effectiveness is high.
