[0039] In order to describe the present invention in detail, the thermal management integrated module of the present invention is specifically described below:

[0040] Please combine Figures 1 to 6As shown, the utility model provides a thermal management integrated module, including a main flow channel plate 10, a secondary flow channel plate 20 and an expansion kettle 80, wherein the main flow channel plate 10 has a first inner side surface and a first outer side surface arranged opposite to each other; the secondary flow channel plate 20 has a second inner side surface and a second outer side surface arranged opposite to each other, the second inner side surface of the secondary flow channel plate 20 is connected to the first inner side surface of the main flow channel plate 10, and a plurality of flow channels are formed between the secondary flow channel plate 20 and the main flow channel plate 10; at least one water pump, a battery cooler 40, a heat exchanger 50 and a multi-way valve 70 are arranged on the first outer side surface of the main flow channel plate 10 and / or the second outer side surface of the secondary flow channel plate 20; the expansion kettle 80 is arranged above the main flow channel plate 10 and the secondary flow channel plate 20.

[0041] Specifically, the thermal management integrated module can be divided into a water channel module component and a cold channel module component, wherein the water channel module component includes: a main channel plate 10 and a secondary channel plate 20, an expansion kettle 80, a water pump, a multi-way valve 70, and a heat exchanger 50; the cold channel module component includes at least: a battery cooler 40. The main channel plate 10 is the main support of the entire thermal management integrated module. A flow channel is formed between the secondary channel plate 20 and the main channel plate 10. The coolant inside the main channel plate 10 flows through different channels in different modes and leads to corresponding components under the drive of the water pump and the regulation of the multi-way valve 70, thereby realizing specific functions in specific modes. The second inner side surface of the secondary channel plate 20 is connected to the first inner side surface of the main channel plate 10. The multiple channel design formed between the two not only optimizes the coolant flow path, but also improves the heat exchange efficiency. The expansion kettle 80 is arranged above the main flow channel plate 10 and the secondary flow channel plate 20, and is used for storing liquid, replenishing water, degassing and maintaining pressure. It can not only accommodate the expansion of the coolant and prevent the coolant from overflowing, but also replenish the coolant and balance the system pressure.

[0042] The thermal management integrated module integrates multiple key components together, and improves the overall performance and reliability of the system through compact layout and optimized structural design. The direction of the flow channel is planned by arranging the water pump and the multi-way valve 70, changing the direction of the water flow and providing a power source; the main flow channel plate 10 and the secondary flow channel plate 20 replace the traditional pipelines, which greatly improves the integration; improves the space utilization, reduces the number of pipelines, and improves the overall module performance.

[0043] In some embodiments, see Figures 1 to 4, the first outer side surface of the main flow channel plate 10 is provided with a first water pump 30, a battery cooler 40 and a heat exchanger 50, and the heat exchanger 50 is located between the first water pump 30 and the battery cooler 40; the second outer side surface of the secondary flow channel plate 20 is provided with a second water pump 60 and a multi-way valve 70, and the first water pump 30 and the second water pump 60 are arranged in a staggered manner. Specifically, the main flow channel plate 10 is provided with a medium interface that is respectively connected to the first water pump 30, the heat exchanger 50, and the battery cooler 40, so as to allow the coolant to circulate in the first water pump 30, the heat exchanger 50, and the battery cooler 40 through different flow channels. The secondary flow channel plate 20 is provided with a medium interface that is respectively connected to the second water pump 60 and the multi-way valve 70, so as to allow the coolant to circulate in the second water pump 60 and the multi-way valve 70 through different flow channels.

[0044] See also Figures 1 to 4 In this example, the heat exchanger 50 is located between the first water pump 30 and the battery cooler 40. This layout is compact and ensures their respective working efficiency. The first water pump 30 and the second water pump 60 are staggered. This layout reduces the interference between the two water pumps and ensures the efficiency and stability of their respective work.

[0045] See also Figure 1 In some embodiments, the main runner plate 10 and the secondary runner plate 20 are arranged vertically, the secondary runner plate 20 is connected to the main runner plate 10, the lower part of the main runner plate 10 has an extended support portion 11, and the support portion 11 is provided with a mounting position 12 for connecting to the vehicle body. Specifically, the main runner plate 10 serves as the main support of the overall module, and two support portions 11 arranged opposite to each other at the lower part of the main runner plate 10 are used to provide a stable support for the main runner plate 10 and enhance the overall rigidity of the main runner plate 10. The support portion 11 is conducive to the main runner plate 10 being more stable when installed on the vehicle body, reducing the performance degradation or safety hazards caused by shaking or vibration. The secondary runner plate 20 is directly connected to the main runner plate 10. This design simplifies the installation process, reduces the alignment and debugging work during assembly, and at the same time, the compact structure also saves installation space. The support portion 11 is provided with a mounting position 12 for connecting to the vehicle body. The design of these mounting positions 12 enables the integrated module to be quickly and accurately installed on the vehicle body, thereby improving the integration efficiency. At the same time, the standardized design of mounting position 12 also facilitates the removal and replacement of the module, reducing maintenance costs and time.

[0046] Continue reading Figure 1 and Figure 3In the above embodiment, a plurality of mounting positions 12 are provided, and a shock-absorbing pad 13 is provided at each mounting position 12. Specifically, four mounting positions 12 can be provided, and they are located at the four corners of the support portion 11, which serve as the mounting points of the integrated module and the whole vehicle. By providing a shock-absorbing pad 13 at each mounting position 12, the vibration isolation and noise reduction performance of the module are greatly enhanced. The shock-absorbing pad 13 can effectively absorb and disperse the vibration and impact from the operation of the vehicle or the operation of the equipment, reduce the impact of these vibrations on the internal components of the module, protect the module from damage, and ensure the stable operation of the thermal management system. The use of the shock-absorbing pad 13 can reduce the wear and fatigue of the module in a vibration environment, thereby extending its service life. The use of the shock-absorbing pad 13 can also reduce the vibration and noise transmitted to the passenger compartment, thereby improving the ride comfort.

[0047] See also Figure 2 , Figures 4 to 6 It should be noted that the first water pump 30, the heat exchanger 50 and the battery cooler 40 are arranged in sequence along the transverse direction of the main flow channel plate 10, the second water pump 60 and the multi-way valve 70 are arranged in sequence along the transverse direction of the secondary flow channel plate 20, and the first water pump 30 is arranged corresponding to the multi-way valve 70, and the second water pump 60 is arranged corresponding to the battery cooler 40. Specifically, the first water pump 30, the heat exchanger 50, and the battery cooler 40 are connected to the main flow channel plate 10 through fasteners (such as screws), and the second water pump 60 and the multi-way valve 70 are connected to the secondary flow channel plate 20 through fasteners (such as screws). The first water pump 30, the heat exchanger 50 and the battery cooler 40 are arranged in a row along the transverse direction of the main flow channel plate 10. This layout makes these key components compactly arranged in the horizontal direction, effectively utilizes space, and improves the integration of the thermal management integrated module. The second water pump 60 and the multi-way valve 70 are arranged in a row along the lateral direction of the secondary flow channel plate 20, and there is a gap between the second water pump 60 and the multi-way valve 70, which also realizes the rational use of space and the compact integration of components. The components are arranged in sequence along the lateral direction of the main flow channel plate 10 and the secondary flow channel plate 20, making the installation process more intuitive and convenient; at the same time, this layout method is also convenient for replacing or repairing components when necessary, reducing maintenance costs and time. Through reasonable layout and corresponding settings of components, the structure of the entire thermal management integrated module is more stable, reducing the risk of loosening or damage of components due to vibration or impact. At the same time, the compact layout also reduces the coolant flow resistance caused by too long pipes or too many elbows, improves the stability and reliability of the system, and ensures a compact structure, rational use of space, and minimizes the layout of pipes.

[0048] See also Figure 3In the above embodiment, the expansion kettle 80 is arranged horizontally, and the expansion kettle 80 is connected to the top of the main flow channel plate 10; the top of the expansion kettle 80 is provided with an exhaust port 83, and the bottom of the expansion kettle 80 is provided with a water replenishment port 84, and the water replenishment port 84 is partially located on the secondary flow channel plate 20. Specifically, the expansion kettle 80 is arranged horizontally. This layout can make more effective use of space. Especially in the limited space of a vehicle or other equipment, the horizontally arranged expansion kettle 80 can reduce the occupied space in the vertical direction, making the entire thermal management integrated module more compact. The expansion kettle 80 is connected to the top of the main flow channel plate 10. This design makes the coolant circulation path smoother, reduces unnecessary pipes and joints, and reduces the risk of coolant leakage. At the same time, the top connection is also convenient for installation and disassembly, which improves the maintenance convenience of the module. The expansion kettle 80 includes an upper kettle body 81 and a lower kettle body 82, and a detachably connected kettle cover 811 is provided on the upper kettle body 81. The top of the expansion kettle 80 is provided with an exhaust port 83, which helps to discharge the gas in the kettle in time during the cooling liquid heating process to prevent the accumulation of gas from causing pressure increase or affecting the cooling effect. The bottom of the expansion kettle 80 is provided with a water replenishment port 84. There are two water replenishment ports 84, one for replenishing coolant in the flow channel formed by the main flow channel plate 10 and the secondary flow channel plate 20, and the other for replenishing coolant in the external pipeline (client motor cooling circuit). This design makes the water replenishment operation more convenient. The water replenishment port 84 is partially located on the secondary flow channel plate 20. This layout makes the water replenishment port 84 closer to the core area of ​​the coolant circulation, which is convenient for timely replenishment of coolant and ensures the normal operation of the system.

[0049] See also Figure 1 and Figure 2 and Figure 5It can be understood that a valve block 91 is provided on the side of the battery cooler 40 facing away from the main flow channel plate 10, and an expansion valve 92 is provided on the valve block 91. An air conditioning pipe interface 93 is provided on the same side of the battery cooler 40 and the valve block 91. Specifically, a valve block 91 is provided on the side of the battery cooler 40 facing away from the main flow channel plate 10, and the expansion valve 92 can be installed on the top of the valve block 91. This layout makes the various components of the cooling system more compact, reduces the length of the pipeline and the connector, and improves the cooling efficiency. At the same time, it is also convenient for the installation, commissioning and maintenance of the battery cooler 40 and the valve block 91. An air conditioning pipe interface 93 is provided on the same side of the battery cooler 40 and the valve block 91, and the air conditioning pipe interface 93 is horizontally arranged and faces the side away from the main flow channel plate 10. This design simplifies the connection process of the air conditioning pipeline. By directly connecting the air conditioning pipe to these interfaces, the number of pipeline joints can be reduced, the risk of leakage can be reduced, and the reliability of the system can be improved. A detachable dust plug 94 is provided on the air conditioning pipe interface 93 to prevent dust when not in use. The integrated design of the valve block 91 and the expansion valve 92 with the battery cooler 40 makes the entire cold circuit module assembly more integrated, improving the integration and coordination of the system. This integrated design not only reduces the complexity of the system, but also improves the overall performance of the system.

[0050] See also Figure 1 , Figure 3 and Figure 5 In the above embodiment, the thermal management integrated module also includes a first water pipe interface 101 arranged on the main channel plate 10 and a second water pipe interface 102 arranged on the secondary channel plate 20. The first water pipe interface 101 and the second water pipe interface 102 are each provided with a plurality of them, and are arranged in a staggered manner. Specifically, a plurality of first water pipe interfaces 101 are provided on the main channel plate 10, and a plurality of second water pipe interfaces 102 are provided on the secondary channel plate 20. This design enables the thermal management integrated module to support more diverse water pipe connection requirements, and these water pipe interfaces are used to connect with external devices. According to the actual application scenario, different water pipe interfaces can be selected for connection to achieve a flexible coolant circulation path, thereby improving the flexibility of the system. At the same time, during maintenance, it is also easier to check and replace the water pipe interfaces, reducing maintenance costs and time. The mutually staggered arrangement also reduces interference and conflict between interfaces, and improves the stability and reliability of interface connections.

[0051] It should be noted that each of the first water pipe interfaces 101 is located in the upper area of ​​the first water pump 30, the heat exchanger 50 and the battery cooler 40, some of the second water pipe interfaces 102 are located between the second water pump 60 and the multi-way valve 70, and some of the second water pipe interfaces 102 are located in the upper area of ​​the multi-way valve 70. Specifically, in this embodiment, three first water pipe interfaces 101 are provided on the main flow channel plate 10, and three second water pipe interfaces 102 are provided on the secondary flow channel plate 20. The three first water pipe interfaces 101 are all located in the upper area of ​​the first water pump 30, the heat exchanger 50 and the battery cooler 40, two second water pipe interfaces 102 are located between the second water pump 60 and the multi-way valve 70, and one second water pipe interface 102 is located in the upper area of ​​the multi-way valve 70. By arranging the water pipe interfaces above or near the cooling components, the installer can more conveniently approach and operate the interfaces when installing the water pipes. This layout reduces the inconvenience and complexity during the installation process and improves the installation efficiency. At the same time, it is easier to check and replace the water pipe interface during maintenance, reducing maintenance costs and time. A reasonable layout of the water pipe interface helps reduce the risk of coolant leakage. By arranging the interface in a position that is easy to observe and operate, potential leakage problems can be discovered and dealt with in a timely manner. In addition, the compact layout also helps reduce the risk of loose or damaged interfaces due to vibration or impact, thereby improving the reliability and stability of the cooling system.

[0052] See also Figure 1 and Figure 3 In addition, each of the first water pipe interface 101, the second water pipe interface 102 and the water filling port 84 of the expansion kettle 80 is detachably connected with a dust cover 103, which can prevent dust, dirt and other impurities from entering the water pipe interface and the water filling port 84 when not in use, keep the interface and the water filling port 84 clean, and reduce faults and unstable factors caused by impurities in the cooling system.

[0053] It can be understood that the thermal management integrated module also includes a wiring harness assembly 110 and a main plug 120 connected to the wiring harness assembly 110, the wiring harness assembly 110 includes a first wiring harness 111 connected to the first water pump 30, a second wiring harness 112 connected to the second water pump 60, a third wiring harness 113 connected to the multi-way valve 70, and a fourth wiring harness 114 connected to the expansion valve 92, and the first wiring harness 111, the second wiring harness 112, the third wiring harness 113 and the fourth wiring harness 114 are connected to the expansion kettle 80 through a clamp 130. Specifically, the wiring harness assembly 110 is provided, and the wiring harness assembly 110 is constrained and positioned by means of the clamp 130. This arrangement ensures that each component can obtain stable power supply and signal transmission through a clear division of labor of the wiring harness, realizes the control feedback and mode regulation of the module, and at the same time, makes the electrical connection of the entire module more orderly and reliable. By providing the clamp 130, the clamp 130 can be plugged into the expansion kettle 80, making the layout of the wiring harness more compact and fixed, reducing the inconvenience caused by the messy wiring harness during installation and maintenance, and improving work efficiency. The wiring harness assembly 110 is connected to an external power supply or control system through the main plug 120, so that a quick and safe electrical connection can be achieved.

[0054] In addition, it should be noted that the thermal management integrated module is particularly suitable for hybrid vehicles (such as PHEV plug-in hybrid vehicles), because the temperature of the coolant is high (up to 125 ℃ ), therefore, higher requirements are put forward for the temperature resistance of the flow channel plate, and traditional flow channel plate materials are no longer applicable. The main flow channel plate 10 and the secondary flow channel plate 20 in the thermal management integrated module are both made of PA66-GF30 (polyamide 66 with 30% glass fiber added). PA66-GF30 has the characteristics of high strength, high heat resistance and high toughness, and can meet the high temperature resistance requirements of hybrid vehicle coolant. The expansion kettle 80 can be made of PP-GF20 material (polypropylene with 20% glass fiber added), and based on the consideration of welding process, the main flow channel plate 10 and the secondary flow channel plate 20 are connected by hot air welding, and the expansion kettle 80 is threadedly connected to the main flow channel plate 10 by fasteners (such as screws).

[0055] Based on the same concept, the present application also provides a vehicle thermal management system, including the thermal management integrated module as described above. In this way, the thermal management system can effectively improve space utilization, facilitate vehicle layout, optimize the connection structure, reduce the number of pipeline connections, and effectively reduce the hidden dangers of refrigerant leakage.

[0056] In summary, the thermal management integrated module and vehicle thermal management system provided by the utility model are connected to the first inner side surface of the main flow channel plate 10 through the second inner side surface of the secondary flow channel plate 20, and multiple flow channels are formed therebetween. The expansion kettle 80 is located above the main flow channel plate 10 and the secondary flow channel plate 20, and at least one water pump, a battery cooler 40, a heat exchanger 50, and a multi-way valve 70 are arranged on the first outer side surface of the main flow channel plate 10 and / or the second outer side surface of the secondary flow channel plate 20, so that the complex pipelines of the system are integrated into an integrated module, which not only simplifies the structure, but also improves the space utilization rate of the whole vehicle, facilitates the layout of the whole vehicle, and improves the product performance; and, the connection structure is optimized, and the number and length of pipeline connections are reduced.
