Detailed Implementation

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0019] The following is for reference. Figures 1-5 This invention describes an integrated thermal management system 100 and a vehicle according to an embodiment of the present invention.

[0020] The integrated thermal management system 100 according to an embodiment of the present utility model includes: The medium flow section 10 has a medium flow channel 20 formed therein. The medium flow section 10 has a plurality of communication interfaces 30, and the plurality of communication interfaces 30 are all connected to the medium flow channel 20. The thermal management module 40 is fixed to the medium flow section 10 and is structurally connected to the medium flow channel 20.

[0021] Among them, such as Figure 1The diagram shows a schematic of the integrated thermal management system 100, which is installed inside the vehicle. Other components connected to the integrated thermal management system 100 are not shown in the diagram. The medium flow section 10 can be constructed as a plate with an internal flow channel structure. Medium flow channels 20 are formed within the medium flow section 10, allowing for the integration of complex piping into the interior. This eliminates a large number of redundant pipe joints, clamps, and excessively long pipes, significantly freeing up space in the engine compartment or under the vehicle. This provides greater flexibility for the arrangement of other components within the vehicle and facilitates a better overall vehicle weight distribution. It greatly simplifies the assembly process, reduces human error, improves overall vehicle production efficiency, and lowers overall vehicle production costs.

[0022] The medium flow section 10 has multiple communication interfaces 30, all of which are connected to the medium flow channel 20. These interfaces 30 can be connected to other components within the vehicle, such as motors, batteries, and condensers. The thermal management module 40 may include components such as a heat exchange device 41, a heating device 42, and a pump assembly 43. The thermal management module 40 is fixed to the medium flow section 10 and structurally connected to the medium flow channel 20. This eliminates the need for mounting brackets, external connecting pipes, joints, and clamps, thus removing redundant pipes and sharp bends between modules. The flow path of the medium (coolant / refrigerant) is shorter and smoother, significantly reducing flow resistance and improving the energy efficiency of the thermal management system. Furthermore, it greatly reduces the size and weight of the integrated thermal management system 100, contributing to vehicle compactness. It also reduces the number of parts, installation steps, and overall vehicle assembly efficiency, thereby lowering production costs and facilitating after-sales maintenance.

[0023] The integrated thermal management system 100 according to this utility model embodiment, by forming a medium flow channel 20 in the medium flow section 10, can integrate complex pipelines into the medium flow section 10, eliminating a large number of redundant pipe joints, clamps, and excessively long pipelines themselves. The thermal management module 40 is fixed to the medium flow section 10, and the thermal management module 40 is structurally connected to the medium flow channel 20, eliminating the need for mounting brackets, external connecting pipes, joints, clamps, and other connecting parts of the thermal management module 40, eliminating redundant pipelines and sharp bends between modules, resulting in a shorter and smoother flow path for the medium, significantly reducing flow resistance, improving the energy efficiency of the thermal management system, and greatly reducing the size and weight of the integrated thermal management system 100, which is beneficial to the compactness of the vehicle, and can also reduce the number of parts, reduce installation procedures, improve the overall assembly efficiency of the vehicle, thereby reducing the production cost of the vehicle, and making after-sales maintenance more convenient.

[0024] According to some embodiments of the present invention, the thermal management module 40 and the medium flow section 10 are detachably connected.

[0025] The thermal management module 40 and the medium flow section 10 are detachably connected. If either the thermal management module 40 or the medium flow section 10 fails, the faulty module can be replaced individually without replacing the entire integrated thermal management system 100, reducing maintenance difficulty and cost. Furthermore, the thermal management module 40 and the medium flow section 10 can be manufactured in parallel, matched to different vehicle models to adapt to various vehicle types without altering the external piping of the integrated thermal management system 100. This enhances the manufacturing and assembly flexibility of the integrated thermal management system 100 and facilitates iterative upgrades of the thermal management module 40 and the medium flow section 10.

[0026] According to some embodiments of the present invention, such as Figure 1 As shown, the thermal management module 40 includes a heat exchange device 41, a heating device 42, and a pump body assembly 43. The heat exchange device 41, the heating device 42, and the pump body assembly 43 are all fixed to the medium flow section 10, and the heat exchange device 41, the heating device 42, and the pump body assembly 43 are all connected to the medium flow channel 20.

[0027] Among them, the heat exchange device 41 can be a heat exchanger, the heating device 42 can be a PTC heater, and the pump body assembly 43 can be an electric water pump. The heat exchange device 41, the heating device 42, and the pump body assembly 43 are integrated into the thermal management module 40, and the heat exchange device 41, the heating device 42, and the pump body assembly 43 are all fixed to the medium flow part 10, so that the integrated thermal management system 100 has the ability to drive, cool, heat, and distribute flow, which greatly compresses the space and releases huge space for the vehicle's front compartment or chassis layout, which is conducive to the compact design of the vehicle.

[0028] Furthermore, the heat exchanger 41, the heating device 42, and the pump assembly 43 are all fixed to the medium flow section 10, so that the connection between the heat exchanger 41, the heating device 42, and the pump assembly 43 can be completed through the medium flow channel 20 in the medium flow section 10. The path is extremely short, almost eliminating external pipelines, forming a highly efficient, short-path heat circulation system, reducing the number of parts, reducing the assembly difficulty and efficiency of the integrated thermal management system 100, and thus reducing the weight and manufacturing cost of the whole vehicle.

[0029] According to some embodiments of the present invention, such as Figures 2-5 As shown, the medium flow channel 20 may include multiple sub-flow channels. The heat exchange device 41, the heating device 42 and the pump body assembly 43 are respectively connected to the corresponding sub-flow channels, and multiple connection interfaces 30 are respectively connected to the corresponding sub-flow channels.

[0030] The medium flow channel 20 includes multiple sub-flow channels. In some embodiments of this invention, the medium flow channel 20 may include two, three, four, five, six, or other numbers of sub-flow channels. However, this invention is not limited to these numbers, and the medium flow channel 20 may also include other numbers of sub-flow channels, as long as the medium flow channel 20 includes multiple sub-flow channels. The number of sub-flow channels can be reasonably set according to the actual situation.

[0031] The heat exchanger 41, heating device 42, and pump assembly 43 are respectively connected to the corresponding sub-channels, and multiple connection interfaces 30 are respectively connected to the corresponding sub-channels. They can be used for different thermal management function loops, realize physical channel isolation and logical function partitioning, and the connection path between multiple sub-channels is more direct and efficient. This avoids the long and winding routes that have to be designed in traditional pipelines to connect various dispersed components, effectively reducing flow resistance, thereby achieving efficient thermal management of the vehicle and improving the vehicle's driving range.

[0032] According to some embodiments of the present invention, such as Figures 2-5 As shown, the multiple sub-channels include: a first sub-channel 21, a second sub-channel 22, and a third sub-channel 23. The pump body assembly 43 includes a first pump body 431, which is connected to the first sub-channel 21. The heat exchange device 41 is connected to the first sub-channel 21 and the second sub-channel 22. The heating device 42 is connected to the second sub-channel 22 and the third sub-channel 23. The multiple connecting interfaces 30 include a first interface 31 and a second interface 32, which are connected to the first sub-channel 21 and the second interface 32 is connected to the third sub-channel 23.

[0033] The first pump body 431 is connected to the first sub-channel 21, the heat exchange device 41 is connected to the first sub-channel 21 and the second sub-channel 22, so that the heat exchange device 41 is connected to the first pump body 431 through the first sub-channel 21, and the heating device 42 is connected to the second sub-channel 22 and the third sub-channel 23, and the heating device 42 is connected to the heat exchange device 41 through the second sub-channel 22.

[0034] Multiple connecting interfaces 30 include a first interface 31 and a second interface 32. The first interface 31 is connected to a first sub-channel 21, allowing the first interface 31 to connect to the first pump body 431 and the heat exchange device 41 via the first sub-channel 21. The second interface 32 is connected to a third sub-channel 23, allowing the second interface 32 to connect to the heating device 42 and the heat exchange device 41 via the third sub-channel 23. Specifically, both the first interface 31 and the second interface 32 can be connected to the battery. The first interface 31 is used for battery liquid return, and the second interface 32 is used for battery liquid inlet. The entire circuit (first pump body 431 - first sub-channel 21 - heat exchange device 41 - second sub-channel 22 - heating device 42 - third sub-channel 23 - battery - return) is dedicated to serving the battery. The first pump body 431, the heat exchange device 41 (cooling), and the heating device 42 (heating) are all connected in series in this circuit. When the first pump body 431 is activated, it can fully propel the coolant to circulate in this circuit, directly acting on the battery, enabling precise and efficient management of the battery temperature.

[0035] According to some embodiments of the present invention, such as Figures 2-5 As shown, the multiple sub-channels also include: a fourth sub-channel 24 and a fifth sub-channel 25, and the multiple connecting interfaces 30 also include a third interface 33 and a fourth interface 34. The fourth sub-channel 24 connects the first sub-channel 21 and the third interface 33, and the fifth sub-channel 25 connects the second sub-channel 22 and the fourth interface 34.

[0036] Both the third interface 33 and the fourth interface 34 can be connected to the expansion tank. The third interface 33 is used for liquid inlet to the expansion tank, and the fourth interface 34 is used for liquid return to the expansion tank. The fourth sub-channel 24 connects the first sub-channel 21 and the third interface 33, allowing the expansion tank to connect to the first pump body 431 and the heat exchange device 41 through the fourth sub-channel 24 and the first sub-channel 21. The fifth sub-channel 25 connects the second sub-channel 22 and the fourth interface 34, allowing the expansion tank to connect to the heating device 42 and the heat exchange device 41 through the fifth sub-channel 25 and the second sub-channel 22. This provides compensation space for the thermal expansion and contraction of the cooling medium. When the temperature of the integrated thermal management system 100 rises, the cooling medium expands, and the excess cooling medium will... The cooling medium is pushed into the expansion tank through the fifth sub-channel 25. When the temperature of the integrated thermal management system 100 decreases, the cooling medium contracts. Under negative pressure, the cooling medium in the expansion tank is drawn back into the integrated thermal management system 100 through the fourth sub-channel 24, keeping the integrated thermal management system 100 always in a full liquid state. This allows the integrated thermal management system 100 to safely cope with the volume changes of the cooling medium across the entire temperature range, maintain the pressure stability of the integrated thermal management system 100, and prevent excessive pressure from damaging components or excessive pressure from causing liquid boiling.

[0037] According to some embodiments of the present invention, such as Figures 2-5As shown, the multiple sub-channels include: a sixth sub-channel 26, multiple connecting interfaces 30 including a fifth interface 35 and a sixth interface 36, the sixth sub-channel 26 connecting the fifth interface 35 and the sixth interface 36, and the pump body assembly 43 including a second pump body 432, the second pump body 432 connecting the sixth sub-channel 26.

[0038] The fifth interface 35 can be connected to the motor for heat dissipation and liquid inlet, the sixth interface 36 can be connected to the condenser, the sixth sub-channel 26 connects the fifth interface 35 and the sixth interface 36, and the pump body assembly 43 includes a second pump body 432, which is connected to the sixth sub-channel 26.

[0039] The second pump body 432, the sixth sub-channel 26, the fifth interface 35, the motor, the condenser, and the sixth interface 36 form a closed-loop cooling circuit for the motor and power electronics (such as the inverter). This prevents the high heat from the motor from "contaminating" the temperature-sensitive battery circuit and also avoids the battery being forced to consume energy to cool the waste heat from the motor. It provides powerful and dedicated cooling capabilities for the motor and electronic control system, ensuring that they do not reduce power due to overheating under continuous high load output, thus guaranteeing the vehicle's acceleration performance. Furthermore, by setting valves, waste heat generated in the motor circuit can be introduced into the battery circuit or the cabin heating circuit, enabling cross-system energy reuse, significantly reducing energy consumption for vehicle heating in winter and improving range.

[0040] Furthermore, the connection between the connection interface 30 and the medium flow channel 20 can be modified according to the vehicle model, such as by adding solenoid valves, which can reduce changes to external pipelines. In addition, the thermal management module 40 can be pre-installed to reduce vehicle assembly time.

[0041] According to some embodiments of the present invention, such as Figure 1 As shown, the integrated thermal management system 100 may further include: a mounting base 50, a medium flow section 10 fixed to the mounting base 50, and the mounting base 50 being adapted to be fixed to an accessory.

[0042] Among them, the adapter can be the vehicle chassis, engine compartment, etc. The medium flow part 10 is fixed to the mounting base 50. The mounting base 50 provides a stable mechanical fixation for the integrated thermal management system 100. The mounting base 50 is suitable for fixing to the adapter, integrating the thermal management module 40 and the medium flow part 10 on the mounting base 50. The mounting base 50 is connected to the same standard mounting point on the vehicle body, eliminating the need for structural components such as mounting brackets and clamps, which can simplify the overall assembly process of the vehicle and improve the production efficiency and production quality of the vehicle.

[0043] According to some embodiments of the present invention, the medium flow section 10 is detachably provided on the mounting base 50.

[0044] The mounting base 50 and the medium flow section 10 are detachably connected. If either the mounting base 50 or the medium flow section 10 fails, the faulty module can be replaced individually without replacing the entire integrated thermal management system 100, reducing maintenance difficulty and costs. Furthermore, the mounting base 50 and the medium flow section 10 can be manufactured in parallel, enhancing the manufacturing and assembly flexibility of the integrated thermal management system 100 and facilitating iterative upgrades of both. Multiple medium flow sections 10 can be matched to different vehicle models, allowing for direct selection of the appropriate medium flow section 10 for each model without redesigning external piping connections or replanning installation locations, thus reducing the development cycle and costs for new vehicle models.

[0045] The vehicle according to the present invention includes the integrated thermal management system 100 of the above embodiment. By forming a medium flow channel 20 in the medium flow section 10, the complex pipelines can be integrated into the medium flow section 10, eliminating a large number of redundant pipe joints, clamps and excessively long pipes themselves. The thermal management module 40 is fixed to the medium flow section 10 and is structurally connected to the medium flow channel 20. The mounting bracket, external connecting pipes, joints and clamps of the thermal management module 40 are eliminated, and the long pipelines and sharp bends connecting the modules are eliminated. The flow path of the medium (coolant / refrigerant) is shorter and smoother, and the flow resistance is significantly reduced, which can improve the energy efficiency of the thermal management system. It can also greatly reduce the volume and weight of the integrated thermal management system 100, which is conducive to the compactness of the vehicle. It can also reduce the number of parts, reduce the installation process, improve the overall assembly efficiency of the vehicle, thereby reducing the production cost of the vehicle and making after-sales maintenance more convenient.
