[0021] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation
[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the embodiments of the present invention.
[0023] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.
[0024] Furthermore, in one embodiment of the present invention, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of embodiments of the present invention, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0025] In one embodiment of the present invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in one embodiment of the present invention according to the specific circumstances.
[0026] Furthermore, the technical solutions of the various embodiments of the present invention can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the protection scope required by the embodiments of the present invention.
[0027] Automotive thermal management systems typically consist of multiple independent heat exchange loops and corresponding components. These components are generally distributed across the vehicle's front compartment or related modules, requiring interconnection via piping. This results in a complex layout and scattered component distribution. Particularly in hybrid vehicles, due to the high integration of the powertrain and the extremely limited space in the engine compartment or installation area, the traditional layout of the thermal management system occupies significant installation space, increasing the difficulty of overall vehicle layout and hindering lightweight design and integrated optimization.
[0028] In view of this, embodiments of the present invention provide a vehicle that integrates at least two of the first heat exchanger, dryer tank, and expansion tank onto the same mounting bracket by setting a mounting bracket fixedly connected to the vehicle frame. This changes the traditional thermal management system where components are scattered and require separate mounting brackets, reducing the number of independent brackets and fixing points required for traditional decentralized installation. In other words, it reduces the number of mounting brackets and connecting structures, integrates the originally scattered components into a modular structure, simplifies the overall structure of the thermal management system, effectively reduces the occupation of the limited chassis space of the vehicle, especially hybrid vehicles, and improves the compactness and utilization of the space layout.
[0029] To better understand the above technical solution, the following detailed explanation is provided in conjunction with the accompanying drawings.
[0030] like Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 10 , Figure 13 as well as Figure 14 As shown in the figure, an embodiment of the present invention provides a vehicle, the vehicle comprising: Frame 100; A thermal management system, comprising: a heating system for heating the passenger compartment; a battery thermal management system for heating or cooling the battery pack; a refrigerant system for supplying refrigerant; an expansion tank 400; and a thermal management integration module 200. The expansion tank 400 is connected to the battery thermal management system. The refrigerant system includes a compressor, a first heat exchanger 510, and a dryer 520 connected in sequence. The battery thermal management system can selectively connect to the first heat exchanger 510 and the heating system via the thermal management integration module 200 to switch between corresponding thermal management modes. A mounting bracket 300 is fixedly connected to the vehicle frame 100. At least two of the first heat exchanger 510, the dryer tank 520, and the expansion tank 400 are integrated into the mounting bracket 300. Optionally, the first heat exchanger 510 and the dryer tank 520 can be integrated into the mounting bracket 300, or the first heat exchanger 510 and the expansion tank 400 can be integrated into the mounting bracket 300, or the dryer tank 520 and the expansion tank 400 can be integrated into the mounting bracket 300, or the first heat exchanger 510, the expansion tank 400, and the dryer tank 520 can be integrated into the mounting bracket 300. The optimal configuration can be selected based on the actual situation. In one embodiment, the mounting bracket 300 can be fixed to the vehicle frame 100 by a bolt structure. Furthermore, three bolts are used for better stability.
[0031] Specifically, in this embodiment, the vehicle includes a frame 100 and a thermal management system. The thermal management system is fixed to the frame 100, which can refer to the structure commonly used in current new energy vehicles or hybrid vehicles, and is not limited here. The thermal management system mainly includes a heating system, a battery thermal management system, a refrigerant system, an expansion tank 400, and a thermal management integration module 200. Each subsystem can refer to common vehicle thermal management models, and will not be described in detail. The thermal management integration module 200 enables the on-demand coupling of each subsystem, thereby meeting the vehicle's thermal management needs under different environmental conditions and operating conditions. Optionally, the thermal management integration module 200 may include multiple control valves (such as solenoid valves, electronic expansion valves, four-way valves, or eight-way valves), flow channels, or pipelines. By controlling the opening and closing of different valves, the battery thermal management system can be connected to the first heat exchanger 510, where it exchanges heat with the refrigerant to cool the battery pack. Alternatively, the battery thermal management system can be connected to the heating system, using the high-temperature fluid in the heating system to heat the low-temperature coolant in the battery thermal management system, thereby heating the battery pack. Alternatively, the high-temperature coolant in the battery thermal management system can heat the low-temperature fluid in the heating system, thus utilizing the waste heat from the battery pack to heat the passenger compartment. The specific switching of thermal management modes can also refer to existing methods and will not be detailed further.
[0032] In this embodiment, by setting a mounting bracket 300 fixedly connected to the vehicle frame 100, at least two of the first heat exchanger 510, dryer tank 520, and expansion tank 400 are integrated onto the same mounting bracket 300. This changes the traditional method of dispersing components in a thermal management system and requiring separate mounting via independent brackets. It reduces the number of independent brackets and fixing points required for traditional distributed installation, thus reducing the number of mounting brackets and connecting structures. The previously scattered components are integrated into a modular structure, simplifying the overall structure of the thermal management system. This effectively reduces the occupation of limited chassis space in vehicles, especially hybrid vehicles, and improves the compactness and utilization of the space layout. Furthermore, the modular integrated design fixes the relative positions of the components, avoiding positioning errors during distributed installation and improving assembly efficiency. Simultaneously, by replacing multiple independent brackets with an integrated mounting bracket 300, the amount of metal materials used is reduced, achieving a lightweight design for the thermal management system, which helps reduce the overall vehicle weight and improve fuel economy or energy efficiency. In addition, the battery thermal management system can selectively connect the first heat exchanger 510 and the heating system through the thermal management integration module 200. When the battery needs to be heated, the heat from the heating system can be used; when the battery needs to be cooled, the heat can be dissipated through the first heat exchanger 510. This allows the corresponding thermal management mode to be switched according to the needs, achieving efficient coordination between battery pack thermal management and passenger cabin thermal management.
[0033] In one embodiment of the present invention, reference is made to... Figure 13 and Figure 14 As shown, the vehicle also includes a power mount 610 connected to the frame 100. The mounting bracket 300, the desiccant 520, the expansion tank 400, and the first heat exchanger 510 are integrated above the power mount 610. This reduces the compression deformation of the tower pack during a collision, decreasing the intrusion into the passenger compartment and reducing injury to occupants, thus improving driving safety. Optionally, the integrated module of the mounting bracket 300, expansion tank 400, desiccant 520, and first heat exchanger 510 has a length of less than 185 mm in the longitudinal direction of the frame 100, further reducing the compression deformation of the tower pack during a collision. Furthermore, the integrated module of the mounting bracket 300, expansion tank 400, desiccant 520, and first heat exchanger 510 is adapted to the arc-shaped structure of the vehicle body cavity, allowing the vehicle body cavity structure to protect the integrated module, thereby improving safety.
[0034] It should be noted that, in this application, the length direction refers to the direction of travel of the vehicle.
[0035] In one embodiment of the present invention, the arrangement direction of the drying tank 520 and the first heat exchanger 510 is parallel to the length direction of the vehicle. It can be understood that the drying tank 520 and the first heat exchanger 510 are arranged side-by-side along the length direction. Thus, during installation, the connecting pipeline can be lengthened for redundancy. When it is necessary to remove the power mount 610, the mounting bracket 300 can rotate horizontally on the frame 100 to expose the power mount 610 underneath. This allows for removal of the power mount 610 without disassembling the connecting pipeline, reducing the difficulty of disassembly and improving the convenience of installation and removal.
[0036] In one embodiment of the present invention, reference is made to... Figure 3 and Figure 4 As shown, the mounting bracket 300 includes a mounting base plate 310, which is fixed to the frame 100 by bolts; The mounting base plate 310 is provided with a first mounting support 320, which is bent and connected to the mounting base plate 310. The expansion kettle 400 is bolted to the first mounting support 320. It is understood that the outer circumferential surface of the expansion kettle 400 has a first mounting position protruding, which is fixed to the first mounting support 320 by bolts, thereby fixing the expansion kettle 400 to the mounting base plate 310; and / or, the mounting base plate 310 is provided with a second mounting support 330, which is bent and connected to the mounting base plate 310. The second mounting support 330 is provided with a mounting side support 340, which is bent and connected to the second mounting support 330. The second mounting support 330 is fixedly connected to the frame 100 via a bend connection. The mounting side support 340 is snap-fitted to the expansion tank 400. It is understood that the outer circumferential surface of the expansion tank 400 has a protruding second mounting position, which is fixedly connected to the mounting side support 340 via a snap-fit. Furthermore, integrating the mounting side support 340 onto the second mounting support 330 brings the fixed position of the expansion tank 400 closer to the fixed position of the mounting base plate 310, improving the overall structural stability. Alternatively, the mounting base plate 310 is provided with a mounting bottom support 350. It is understood that the mounting bottom support 350 supports the bottom of the expansion tank 400, further improving the reliability of the expansion tank 400's fixation. The mounting bottom support 350 has a soft pad for supporting the expansion tank 400, which absorbs vibration, further improving the reliability of the expansion tank 400's fixation.
[0037] In one embodiment of the present invention, the mounting base plate 310 is provided with a mounting position for fixing the vehicle frame 100, and the mounting position is offset from the dryer tank 520, the expansion tank 400, and the first heat exchanger 510. It is understood that the mounting base plate 310 can be fixed to the vehicle frame 100 through the provided mounting position. Furthermore, the mounting position is offset from the dryer tank 520, the expansion tank 400, and the first heat exchanger 510, meaning that the dryer tank 520, the expansion tank 400, and the first heat exchanger 510 will not obstruct the mounting position, allowing for direct assembly and disassembly using bolts, thus improving operational convenience.
[0038] In one embodiment of the present invention, the thermal management integrated module 200 is located in the central channel of the vehicle body on the side near the passenger compartment. In this way, it can avoid the collision path of the vehicle's powertrain and catalytic converter 820, reduce the amount of intrusion into the passenger compartment during a vehicle collision, and improve the safety of the occupants.
[0039] In one embodiment of the present invention, the thermal management integration module 200 is located below the area corresponding to the passenger's feet in the front passenger compartment. This area is typically unused or only used for laying a small number of wiring harnesses / pipes in conventional vehicles, and is not effectively utilized. By placing the thermal management integration module 200 in this unused space, the occupation of other spaces can be reduced, further optimizing the overall vehicle space layout. In this embodiment, the area corresponding to the passenger's feet refers to the area where the passenger's feet naturally rest when seated in the front passenger seat.
[0040] In one embodiment of the present invention, reference is made to... Figure 6 , Figure 7 , Figure 12 , Figure 15 as well as Figure 16The heating system includes a connected heater pump, a third heat exchanger 720, an electric heater 710, and a heater unit. The first heat exchanger 510 is connected to the third heat exchanger 720 via a dryer tank 520 and the compressor. The heater unit is connected to the battery thermal management system via the thermal management integration module 200. Specifically, the heater pump drives the liquid in the heating pipes to flow. After being heated by the electric heater 710, the liquid flows into the heater unit, which blows hot air into the passenger compartment. The hot air then flows back to the electric heater 710 for further heating, and the cycle repeats. When it is necessary to use the high-temperature liquid in the heating system to heat the battery pack, the battery thermal management system is connected to the heater unit via the thermal management integration module 200. In addition, when the waste heat of the battery pack needs to be used to heat the liquid in the heating system, the battery thermal management system is connected to the first heat exchanger 510 through the thermal management integration module 200. The refrigerant in the refrigerant system exchanges heat with the liquid in the battery pack pipeline system in the first heat exchanger 510. After absorbing heat, it flows to the third heat exchanger 720. The liquid in the heating system exchanges heat with the high-temperature refrigerant in the third heat exchanger 720, so that the liquid in the heating system is heated and flows to the heating unit.
[0041] In one embodiment of the present invention, reference is made to... Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 12 As shown, the vehicle also includes a front bulkhead crossbeam 620, a powertrain 810, and a catalytic converter 820. The electric heater 710 and the third heat exchanger 720 are located above the plane containing the powertrain 810 and the catalytic converter 820, and behind the plane containing the front bulkhead crossbeam 620. It can be understood that the powertrain 810 and the catalytic converter 820 are located on a first plane extending in the length and width directions of the frame 100, with the electric heater 710 and the third heat exchanger 720 located above this first plane; the front bulkhead crossbeam 620 is located on a second plane extending in the width and height directions of the frame 100, with the electric heater 710 and the third heat exchanger 720 located behind this second plane. In this way, the catalytic converter 820 and the powertrain 810 can be avoided in the height direction of the frame 100. After a collision, the powertrain 810 can drive the exhaust system to compress the front bulkhead, improving driving safety.
[0042] In one embodiment of the present invention, reference is made to... Figure 7 , Figure 15 as well as Figure 16The heating system also includes a controller 730, which is electrically connected to the electric heater 710. The controller 730 is located above the powertrain 810, the catalytic converter 820, and the electric heater 710, and is offset from the catalytic converter 820 and the powertrain in the vehicle's height direction. This further ensures that, after a collision, the powertrain 810 can drive the exhaust system to compress the front bulkhead, thereby improving driving safety.
[0043] In one embodiment, the electric heater 710 includes a heating shell, a heating channel disposed inside the heating shell, a liquid inlet communicating with the heating channel, and a liquid outlet communicating with the heating channel. The liquid inlet and the liquid outlet are located on the same side of the heating shell and are spaced apart along the height direction of the heating shell. This allows the liquid inlet and liquid outlet pipes to be connected in the same area, avoiding the pipes running around the heating shell, reducing pipe bends and connection lengths, and resulting in a more regular and compact pipe layout. For vehicles with limited engine compartment or chassis space, such as hybrid vehicles, this reduces the space occupied by the surrounding area and facilitates the integrated layout of the vehicle's thermal management system. Furthermore, with the liquid inlet at the bottom and the liquid outlet at the top, when the electric heater 710 is working, the coolant flows into the heating channel from below, decreases in density after being heated, and naturally flows upwards, consistent with the pumping circulation direction, which helps reduce flow resistance and lower water pump energy consumption. At the same time, it facilitates the upward aggregation of air bubbles in the heating channel under the action of buoyancy and their discharge from the higher liquid outlet, effectively avoiding the problem of local overheating or uneven heating caused by air bubble retention, thus improving heating efficiency and operational reliability.
[0044] In one embodiment of the present invention, reference is made to... Figure 11 The thermal management integrated module 200 includes a flow channel plate 210, a first flow path switching structure 220, and a second heat exchanger 230. The first flow path switching structure 220 and the second heat exchanger 230 are integrated on the flow channel plate 210, and the flow channel plate 210 is provided with multiple independent flow channels. The second heat exchanger 230 is connected to the first flow path switching structure 220 and the heating system through a corresponding flow channel. The battery thermal management system is connected to the first flow path switching structure 220, the second heat exchanger 230, and the first heat exchanger 510 through a corresponding flow channel. The first heat exchanger 510 is connected to the battery thermal management system and the drying tank 520.
[0045] It is understood that this embodiment integrates the first flow path switching structure 220 and the second heat exchanger 230 onto the flow channel plate 210, and connects them through the internal flow channels of the flow channel plate 210, thereby reducing the number of connecting pipes and further simplifying the structure. Specifically, the first flow path switching structure 220 can be a solenoid valve, a multi-way valve, etc.
[0046] In this embodiment, the flow channel plate 210 is provided with a first interface, a second interface, and a third interface. The first interface connects to the battery water pump and two flow channels. One flow channel connects to the first valve port of the first flow path switching structure 220, and the other flow channel connects to a heat exchange channel of the second heat exchanger 230. This heat exchange channel of the second heat exchanger 230 is connected to the second valve port of the first flow path switching structure 220 via the flow channel. The second interface connects to another heat exchange channel of the second heat exchanger 230 and the heater unit. The third interface connects to the third valve port of the first flow path switching structure 220 and a heat exchange channel of the first heat exchanger 510. This heat exchange channel of the first heat exchanger 510 is connected to the battery water pump via a pipe. When the waste heat from the battery pack needs to provide heat to the heating system, the first and third valve ports of the first flow path switching structure 220 are opened. When the second heat exchanger 230 is used to heat the battery pack, the second and third valve ports of the first flow path switching structure 220 are opened.
[0047] In one embodiment of the present invention, reference is made to... Figure 11 The thermal management integrated module 200 further includes a second flow path switching structure 240, and the thermal management system further includes an engine system. The second flow path switching structure 240 is integrated into the flow channel plate 210. The engine system and the heating system are respectively connected to the second flow path switching structure 240 through corresponding flow channels. The second flow path switching structure 240 is connected to the second heat exchanger 230 through corresponding flow channels.
[0048] It is understood that this embodiment integrates the second flow path switching structure 240 onto the flow channel plate 210 and connects the corresponding engine system through the internal flow channels of the flow channel plate 210, thereby reducing the number of connecting pipes and further simplifying the structure. Specifically, the second flow path switching structure 240 can be a solenoid valve, a multi-way valve, etc.
[0049] In this embodiment, the flow channel plate 210 is provided with a fourth interface, a fifth interface, and a sixth interface. The fourth interface connects to the first valve port of the second flow path switching structure 240 and the heater pump; the fifth interface connects to the second valve port of the second flow path switching structure 240 and the engine; and the sixth interface connects to another heat exchange channel of the second heat exchanger 230. It can be understood that the sixth interface and the heater unit are connected to the same heat exchange channel of the second heat exchanger 230, with one serving as an input and the other as an output. Simultaneously, the third valve port of the second flow path switching structure 240 connects to the flow channel where the second interface is located. When it is necessary to use the engine's waste heat to heat the battery pack, the second valve port and the first valve port of the second flow path switching structure 240 open.
[0050] In this application, the thermal management system may include the following modes: The battery pack is heated by the first heat exchanger 510. Specifically, the high-pressure, high-temperature refrigerant flowing out of the compressor flows directly through the third heat exchanger 720 without exchanging heat with other liquids, and then flows through the external condenser to the first heat exchanger 510. In the first heat exchanger 510, the battery pack thermal management system exchanges heat with the high-temperature, high-pressure refrigerant of the refrigerant system, and the temperature of the coolant in the battery pack thermal management system rises, thereby heating the battery pack.
[0051] The waste heat from the battery pack is used to heat the passenger compartment. Specifically, the high-pressure, high-temperature refrigerant flowing out of the compressor flows into the third heat exchanger 720. The low-temperature liquid in the heating pipes and the high-pressure, high-temperature refrigerant exchange heat in the third heat exchanger 720. The high-pressure, high-temperature refrigerant becomes low-temperature refrigerant and flows to the first heat exchanger 510 after passing through the external condenser. In the first heat exchanger 510, it absorbs the heat from the coolant in the battery thermal management system and then flows back to the compressor, and then to the third heat exchanger 720.
[0052] The battery pack is heated by the heating system. Specifically, the air conditioning unit is connected to the second heat exchanger 230. The high-temperature liquid flowing out of the air conditioning unit exchanges heat with the low-temperature coolant in the battery thermal management system in the second heat exchanger 230. The heated coolant flows to the battery water pump through the first flow path switching structure 220 and the first heat exchanger 510. The cooled liquid in the heating system flows back to the heating water pump through the third valve port and the first valve port of the second flow path switching structure 240. After being heated by the electric heater 710, it flows back to the second heat exchanger 230 through the air conditioning unit.
[0053] The waste heat of the engine is used to heat the liquid in the heating system. Specifically, the high-temperature liquid in the engine system flows into the heating water pump through the second valve port of the second flow path switching structure 240 and the first valve port of the second flow path switching structure 240. After the air conditioning unit blows hot air into the passenger compartment, the liquid flows back to the engine system through the second heat exchanger 230 and the sixth interface.
[0054] In one embodiment of the present invention, the flow path connection ports of the first flow path switching structure 220 and / or the second flow path switching structure 240 are integrated on the flow channel plate 210. This further reduces the use of connecting pipes, resulting in a simpler structure.
[0055] The above description is merely an exemplary embodiment of the present invention and does not limit the scope of protection of the embodiments of the present invention. Any equivalent structural transformations made under the technical concept of the present invention using the description and drawings of the embodiments of the present invention, or direct / indirect applications in other related technical fields, are included within the scope of protection of the embodiments of the present invention.
