Technical Field

[0001] This invention relates to the field of water circuit technology for liquid coolers, and particularly to a low-resistance water circuit assembly with an integrated water pump. Background Technology

[0002] With the development of new energy technologies, safety has become increasingly important. Lithium-ion batteries are prone to thermal runaway due to overcharging, puncture, or impact, which can lead to smoke, fire, or even explosion. Furthermore, the performance of power lithium batteries, including energy density and lifespan, is affected by temperature changes, further highlighting the importance of thermal management. Current technologies often utilize liquid cooling units for thermal management of lithium batteries.

This arrangement also occupies a large amount of internal space, requiring the chiller to operate at high power to meet the unit's cooling airflow requirements. This contradicts national energy conservation and emission reduction strategies and corporate goals for cost reduction and efficiency improvement. Furthermore, the dispersed water circuit components are complex to install, hindering rapid disassembly and assembly, and impeding equipment assembly, maintenance, and repair.

A quick-connect assembly is fixedly installed between the four-way connector 31 and the pump head 2.

[0039] The quick-connect assembly is used to enable quick assembly and disassembly between the pump head 2 and the four-way connector 31. The quick-connect assembly includes a first connecting pipe 21 and a second connecting pipe 22. The first connecting pipe 21 is fixedly installed in the middle of the pump head 2, and the second connecting pipe 22 is fixedly installed in the middle of the four-way connector 31. A sealing groove 23 is provided at the end of the first connecting pipe 21 and the second connecting pipe 22 that are close to each other.

[0040] Furthermore, the bottom of the sealing groove 23 is provided with an arc-shaped extension groove 231, and both sides of the annular sealing ring 24 are fixedly provided with extension portions 241, and the extension portions 241 correspond to the extension groove 231. During the process of pressing the first connecting pipe 21 and the second connecting pipe 22 together, the two extension portions 241 are squeezed and deformed in the direction of the annular sealing ring 24, so that the annular sealing ring 24 deforms outward and completely seals the gap between the first connecting pipe 21 and the second connecting pipe 22, thereby improving its sealing effect.

[0041] The quick-connect assembly also includes a protrusion 25, a locking block 26, and a pressing block 27. The protrusion 25 is mounted around one end of the first connecting pipe 21, and the outer side of the protrusion 25 is set with an inclined structure. The inner sidewall of the second connecting pipe 22 is provided with multiple slots 261. Multiple locking blocks 26 are provided, and the multiple locking blocks 26 are respectively inserted into the multiple slots 261. The inner side of the locking block 26 is set with an inclined structure corresponding to the protrusion 25. The outer sidewall of the locking block 26 is provided with a pressing part 262 with an inclined structure. The pressing block 27 is slidably mounted on the outer side of the locking block 26, and one end of the pressing block 27 is set with an inclined structure corresponding to the pressing part 262.

[0042] The drive assembly is used to drive the extrusion block 27. The drive assembly includes a transmission rod 271, a guide portion 272, a guide groove 273, a connecting portion 274, and a positioning nut 275.

The connecting part 274 is sleeved and installed on the outside of the second connecting pipe 22. The positioning nut 275 is rotatably installed on one end of the connecting part 274 and threaded on the middle of the second connecting pipe 22. Under the action of the thread, the positioning nut 275 drives the connecting part 274 to move horizontally. The connecting part 274 can drive the pressing block 27 to move through the transmission rod 271. The pressing block 27 presses the pressing part 262 on the outside of the locking block 26, so that the locking block 26 moves toward the protrusion 25 until the locking block 26 locks the position of the protrusion 25.

[0043] The quick-connect assembly also includes a pressure plate 28 and a movable plug 29. The pressure plate 28 is fixedly installed inside the second connecting pipe 22, and the movable plug 29 is slidably installed inside the first connecting pipe 21. One end of the movable plug 29 is fixedly installed with a pressure rod 291 corresponding to the pressure plate 28. The interior of the movable plug 29 is provided with multiple "L"-shaped connecting grooves 292. The other end of the movable plug 29 is installed with a fixing seat 293 by a spring 294, and the fixing seat 293 is fixedly installed inside the first connecting pipe 21.

[0044] The quick-connect assembly also includes a sealing groove 295 and a flow groove 296 formed inside the first connecting pipe 21. The diameter of the movable plug 29 corresponds to that of the sealing groove 295, and the diameter of the movable plug 29 is smaller than that of the flow groove 296. When the first connecting pipe 21 is separated from the second connecting pipe 22, the movable plug 29 slides into the sealing groove 295 under the action of the spring 294. At this time, the first connecting pipe 21 can be sealed to prevent leakage of circulating water during disassembly and maintenance.

[0045] Furthermore, a flow guide block 281 is fixedly installed in the middle of the inner side of the pressure plate 28, and the flow guide block 281 is set as a hemispherical structure. The setting of the hemispherical structure allows the flow guide block 281 to guide the circulating water through the pressure plate 28.

[0046] Plate heat exchanger 4 is fixedly installed on the outside of mounting base 11 by bolts. The input end of plate heat exchanger 4 is fixedly installed on the top inside of flow channel 13, and the output end of plate heat exchanger 4 is fixedly installed inside guide groove 12. PTC heater 5 is fixedly installed on the top of integrated module 1, and the input end of PTC heater 5 is fixedly installed on the top inside of guide groove 12. Water outlet pipe 6 is fixedly installed on the output end of PTC heater 5.

[0047] Furthermore, a first water pressure sensor 34 for monitoring water pressure is fixedly installed between the four-way valve 31 and the expansion tank 33. A second water pressure sensor 35 for monitoring inlet water pressure is fixedly installed in the middle of the inlet pipe 3. A third water pressure sensor 61 for monitoring outlet water pressure is fixedly installed in the middle of the outlet pipe 6. The pressure monitoring of each position inside the water circuit can be achieved through the first water pressure sensor 34, the second water pressure sensor 35 and the third water pressure sensor 61. When the water pressure in the water circuit decreases, circulating water can be replenished into the water circuit through the water replenishment pipe 32 to ensure the stable operation of the water circuit.

[0048] In summary, during use, the water pump is bolted to one end of the pump head 2, and the pump blades are installed inside the pump head 2. The inlet pipe 3 is connected to the input end of the pump head 2 via a quick-connect assembly. The plate heat exchanger 4 and the PTC heater 5 are both installed on the outside of the integrated module 1. The outlet pipe 6 is installed at the output end of the PTC heater 5. During use, circulating water enters the pump head 2 through the inlet pipe 3 and enters the plate heat exchanger 4 under the drive of the pump blades. After heat exchange in the plate heat exchanger 4, the circulating water enters the PTC heater 5 for heating. The heated circulating water is discharged through the outlet pipe 6. By connecting the outlet pipe 6 and the inlet pipe 3 with a connecting water pipe, the water circulation can be realized. During use, the pressure at various locations inside the water circuit can be monitored by the first water pressure sensor 34, the second water pressure sensor 35, and the third water pressure sensor 61. When the water pressure in the water circuit decreases, circulating water can be added to the water circuit through the water replenishment pipe 32 to ensure the stable operation of the water circuit.

[0049] During the assembly of the water system, the pump head 2 and the four-way connector 31 at the bottom of the inlet pipe 3 are connected by a quick-connect assembly. During this process, the first connecting pipe 21 installed in the middle of the pump head 2 and the second connecting pipe 22 installed in the middle of the four-way connector 31 can be spliced ​​together. The first connecting pipe 21 can be inserted into the guide portion 272 at one end of the second connecting pipe 22. During insertion, the protrusion 25 at one end of the first connecting pipe 21 can press against the locking block 26, causing the locking block 26 to slide into the slot 261. When the first connecting pipe 21 is fully inserted into the guide... After the part 272 moves to the inside of the locking block 26, the protrusion 25 moves to the inside of the locking block 26. At this time, the positioning nut 275 is rotated. Under the action of the thread, the positioning nut 275 drives the connecting part 274 to move horizontally. The connecting part 274 can drive the pressing block 27 to move through the transmission rod 271. The pressing block 27 presses the pressing part 262 on the outside of the locking block 26, so that the locking block 26 moves toward the protrusion 25 until the locking block 26 locks the position of the protrusion 25. At this time, the position between the first connecting pipe 21 and the second connecting pipe 22 can be locked.

[0050] During the assembly of the first connecting pipe 21 and the second connecting pipe 22, the pressure plate 28 inside the second connecting pipe 22 presses the pressure rod 291 inside the first connecting pipe 21, causing the pressure rod 291 to drive the movable plug 29 to move until the movable plug 29 slides from the sealed groove 295 into the flow groove 296. At this time, the circulating water in the second connecting pipe 22 can flow into the first connecting pipe 21 through the connecting groove 292 and the flow groove 296 inside the movable plug 29 to realize the connection of the water circuit. When the first connecting pipe 21 and the second connecting pipe 22 are separated, the movable plug 29 slides into the sealed groove 295 under the action of the spring 294, which can seal the first connecting pipe 21 to prevent leakage of circulating water during disassembly and maintenance.

[0051] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
