In the drawings, the thicknesses of layers and regions are exaggerated for clarity, and the same reference numerals are used throughout the drawings to refer to the same components, and thus a description thereof will be omitted.

[0023] In conjunction with Figures 1 to 4As shown, according to the specific embodiments of the present application, a flow channel plate assembly is provided, comprising: a flow channel plate body 101, a plurality of cooling flow channels 102 are arranged on the flow channel plate body 101, the plurality of cooling flow channels 102 are integrally formed, different cooling flow channels 102 are used to perform thermal work on different target components, the plurality of cooling flow channels 102 are coupled to each other to form a complete thermal management loop, the cooling flow channels 102 include an electric drive cooling flow channel 10, a battery cooling flow channel 30 and a cockpit thermal flow channel 20, a cutoff piece is arranged inside the cooling flow channel 102 and / or at the end of the cooling flow channel 102, the cutoff piece has a cutoff position for cutting off the cooling flow channel 102 to shield the cooling flow channel 102 from the complete thermal management loop, and the cutoff piece has an open position for opening at least part of the cooling flow channel 102 to couple the cooling flow channel 102 with the remaining cooling flow channels 102 to form the complete thermal management loop.

[0024] By integrally forming the plurality of cooling flow channels 102 and using different cooling flow channels 102 to perform thermal work on different target components, the application of the technical solution of the present application realizes the integration of the electric drive cooling flow channel 10, the battery cooling flow channel 30 and the cockpit thermal flow channel 20, cancels the existing pipeline distributed design, and further reduces the number of connecting pipelines, shortens the assembly time and reduces the risk of leakage. Moreover, the cutoff piece can shield part of the cooling flow channels in the complete thermal management loop, so that the flow channel plate can be applied to different vehicle models, and only the corresponding flow channels need to be shielded. The present application effectively solves the problem of poor universality of the flow channel plate design in the prior art.

[0025] The technical solution of the present application provides an integrated flow channel plate assembly, which includes a plurality of integrally formed cooling flow channels for the thermal management needs of different target components such as electric drives, batteries and cockpits. These cooling flow channels can be coupled to each other to form a complete thermal management loop, reducing the number of existing soft pipe connections. Further, the number of connecting pipelines can be reduced, the assembly time can be shortened, and the risk of leakage can be reduced, realizing the selective coupling of the electric drive cooling flow channel 10, the cockpit thermal flow channel 20 and the battery cooling flow channel 30, so that the three pipelines can perform heat exchange work in time, improving the energy utilization efficiency of the vehicle. The present application solves the problem of many leakage points of the vehicle thermal management system in the prior art.

[0026] The technical solution of the present application controls the cutoff piece, and the cutoff piece (such as a plug or a cutoff valve) inside or at the end of the cooling flow channel can be detached or controlled to open and close, allowing some cooling flow channels to be shielded, thereby enhancing the flexibility and applicability of the flow channel plate, enabling it to adjust the thermal management strategy in different vehicle models.

[0027] Thermal operation includes heating or warming, and cooling. The interconnection between multiple cooling flow channels includes: direct connection: multiple cooling flow channels are directly connected through valves, tees, heat exchangers or manifold chambers, etc., to form shared fluid passages or branch networks, and the selectivity of different cooling flow channels can be realized by reasonable valve connection control. Thermal coupling: different pipelines exchange heat through heat exchangers (such as plate heat exchangers), heat pipes or shared heat dissipation components (such as front end modules), resulting in mutual influence of temperature fields.

[0028] Further, the flow channel plate body 101 includes: a first plate layer 1 and a second plate layer 3, the first plate layer 1 and the second plate layer 3 are arranged adjacent along a first direction, the second plate layer 3 is located at the bottom of the first plate layer 1, part of the cooling flow channels 102 are located in the first plate layer 1, and another part of the cooling flow channels 102 are located in the second plate layer 3, the cooling flow channels 102 located in the first plate layer 1 are in direct communication with the cooling flow channels 102 located in the second plate layer 3, or the cooling flow channels 102 located in the first plate layer 1 are in indirect communication with the cooling flow channels 102 located in the second plate layer 3 through a thermal management accessory, the thermal management accessory including at least one of a water pump 103, a PTC heater 104 and a heat exchanger 40.

[0029] The flow channel plate body is divided into a first plate layer and a second plate layer, each plate layer contains part of the cooling flow channels, and the flow channels of different plate layers are indirectly connected through a thermal management accessory (such as a water pump, a heater and a heat exchanger), so that modular assembly is realized, the assembly difficulty and the leakage risk are reduced, and the arrangement convenience of the height space in exchange for the horizontal and vertical space can be realized.

[0030] By distributing the cooling flow channels in different plate layers, modular design can be realized, the cooling demand adjustment and optimization of different components are facilitated, the customizability and flexibility of the flow channel plate are improved, and it is beneficial to quickly adapt to the thermal management needs of various vehicle models.

[0031] The direct communication or indirect communication of the first plate layer and the second plate layer through the thermal management accessory reduces the complexity and assembly difficulty brought by the traditional pipeline connection, reduces the risk of leakage, and also simplifies the vehicle assembly process and reduces the production cost.

[0032] The introduction of thermal management accessories such as water pumps, PTC heaters and heat exchangers can be flexibly configured according to actual thermal management needs, such as accelerating the cooling liquid circulation, adjusting the cooling liquid temperature or exchanging heat, so as to effectively improve the overall functionality and heat exchange efficiency of the thermal management system.

[0033] Optionally, more layers of plates are added on the basis of the original two layers of plates, and specific cooling flow channels are designed on each layer of plates to cope with more complex or advanced thermal management needs. The multiple layers of plates can be interconnected through precise valves and pipeline systems to form a highly adjustable thermal management system.

[0034] In addition to the temperature sensor, an intelligent temperature control device such as an electronic expansion valve or a smart thermoelectric cooler (TEC) can be added in each cooling channel 102 to dynamically adjust the cooling intensity according to the real-time monitored temperature, achieve precise temperature control, and thus improve energy utilization efficiency and reduce energy consumption.

[0035] Further, at least one of the first plate layer 1 and the second plate layer 3 comprises a bottom plate 105, and a plurality of channel cover plates are provided one-to-one corresponding to the cooling channels 102, and the opening side of each channel cover plate is connected with the bottom plate 105, and each channel cover plate forms a flow groove, and each flow groove and the bottom plate 105 form a cooling channel 102 corresponding to the channel cover plate.

[0036] Optionally, the bottom plate 105 and the channel cover plate are integrally casted.

[0037] Optionally, since each channel cover plate corresponds to one cooling channel, when maintaining or replacing a part of the cooling channel, the entire system does not need to be disassembled, only the corresponding channel cover plate needs to be removed, which reduces the maintenance cost and time and improves the maintainability of the system.

[0038] In another optional embodiment, the channel cover plate is manufactured separately from the bottom plate 105 and then assembled, which can more easily control the size and shape accuracy of the cooling channel, and also facilitates standardized mass production on the production line, improving manufacturing efficiency.

[0039] The close contact between the bottom plate 105 and the channel cover plate, and the flow grooves formed in the channel cover plate, help to enhance the heat exchange between the cooling liquid and the channel plate body, and improve the overall efficiency of the thermal management system.

[0040] By simply adding or replacing the channel cover plate, the layout of the cooling channel can be expanded or changed to adapt to different vehicle models or future vehicle thermal management upgrade requirements, improving the flexibility and customization ability of the system.

[0041] In another optional embodiment, the channel cover plate can be designed in different shapes and sizes to adapt to the cooling needs of different power or size target components, or even designed with built-in cooling fins to enhance the local heat exchange effect.

[0042] Further, at least one electromagnetic valve is provided on the first plate layer 1, and at least part of the cooling channels 102 are in communication with different ports of the same electromagnetic valve to structureally couple at least part of the cooling channels 102 by the electromagnetic valve.

[0043] At least one electromagnetic valve is arranged on the first plate layer, and part of the cooling flow channels are coupled by the electromagnetic valve, so that the connection mode between the flow channels is optimized, and extra pipelines and interfaces are reduced.

[0044] Further, at least one of the first plate layer 1 and the second plate layer 3 comprises: a fixed plate block connected with the mounting base, the fixed plate block being provided with part of the cooling flow channels 102; a spliced plate block provided with part of the cooling flow channels 102, the spliced plate block having a connection position connected with the fixed plate block and a disconnection position disconnected with the fixed plate block, and when the spliced plate block is in the connection position, the spliced plate block is located on one side of the fixed plate block and the cooling flow channels 102 on the spliced plate block are coupled with the cooling flow channels 102 on the fixed plate block to form a complete thermal management loop.

[0045] The part of the plate layers in the flow channel plate can be the spliced plate block which can be connected or disconnected without affecting the normal work of other cooling flow channels, so that the maintenance and upgrading process is simplified.

[0046] Through the combination of the fixed plate block and the spliced plate block, the layout of the cooling flow channels can be quickly adjusted according to the thermal management requirements of different vehicle models, and only specific plate blocks need to be replaced or spliced, without the need to customize a complete flow channel plate assembly, so that the design flexibility and applicability are greatly improved.

[0047] The arrangement of the spliced plate block allows installation and maintenance without damaging the fixed plate block, reduces the difficulty and cost of maintenance, and also facilitates on-site service and upgrading.

[0048] The fixed plate block and the spliced plate block can be independently produced and then combined during assembly, and such a modular production method helps to improve production efficiency and facilitates quality control and inventory management.

[0049] For different vehicle models, only specific spliced plate blocks need to be customized, and the fixed plate block can be used as a universal component, greatly reducing the customization cost and period caused by changes in vehicle models.

[0050] If it is necessary to increase or modify the cooling flow channels, only the spliced plate block needs to be operated, without the need to change the entire system, so that future system upgrading or function expansion becomes easier.

[0051] A quick locking mechanism such as a buckle, magnetic attraction or a special quick connector is designed at the connection position of the fixed plate block and the spliced plate block to ensure quick installation and disconnection of the spliced plate block and ensure the stability and sealing of the connection.

[0052] Further, the cutoff member includes a plug, the plug is detachably connected with the end opening of the cooling flow channel 102, and the cutoff member is in the cutoff position when the plug is connected with the end opening of the cooling flow channel 102. This design allows the opening or closing of a specific cooling flow channel through a simple physical operation (such as tightening or loosening), so that part of the thermal management system can be selectively enabled or disabled according to actual needs, for example, in a low-temperature environment, the battery cooling flow channel can be closed to save energy. In addition, the detachable feature also facilitates maintenance and troubleshooting, without the need to disassemble the entire system to replace or inspect components. For different vehicle models, the above-mentioned method can also be used to achieve universality.

[0053] Further, the cutoff member includes a cutoff valve, the cutoff valve is located inside the cooling flow channel 102, and the cutoff member is in the cutoff position when the cutoff valve executes the closing instruction sent by the controller.

[0054] Further, at least one of a temperature sensor and a flow sensor is arranged in the cooling flow channel 102, the temperature sensor is used to collect the temperature of the fluid in the cooling flow channel 102, and the flow sensor is used to collect the flow of the fluid in the cooling flow channel 102 per unit time. The integration of temperature sensors and flow sensors inside the cooling flow channel can monitor the temperature and flow of the cooling liquid in real time, providing key data for the thermal management system, which is used to dynamically adjust the cooling strategy, avoid overcooling or overheating, protect vehicle components, and prolong the service life. The integration of sensors also simplifies system design, reduces external connections, and improves the overall reliability and safety of the system.

[0055] Further, the adjacent cooling flow channels 102 are filled with thermal insulation materials, and / or the outer side of the flow channel cover plate is coated with a thermal insulation coating, and / or the inner side of the flow channel cover plate is sprayed with an infrared reflective coating. Filling thermal insulation materials between adjacent cooling flow channels, and using thermal insulation coatings and infrared reflective coatings on the inner and outer sides of the flow channel cover plate, effectively reduces heat conduction and avoids thermal interference between different target components, improving the efficiency and performance of the thermal management system. At the same time, the thermal insulation measures also help to reduce the energy consumption of the entire system, especially for vehicles operating in high-temperature environments, which can effectively reduce the load of the cooling system.

[0056] According to one aspect of the present application, a thermal management system is provided, including a flow channel plate assembly, which is the flow channel plate assembly described above.

[0057] According to one aspect of the present application, a vehicle is provided, including a thermal management system, which is the flow channel plate assembly described above.

[0058] Figure 1The first electromagnetic valve 2 is shown in the middle, the electric drive cooling flow channel 10, the cockpit heat flow channel 20 and the battery cooling flow channel 30 are communicated with different ports of the first electromagnetic valve 2, the electric drive cooling flow channel 10 is selectively communicated with the cockpit heat flow channel 20 through the first electromagnetic valve 2, and the electric drive cooling flow channel 10 is selectively communicated with the battery cooling flow channel 30 through the first electromagnetic valve 2.

[0059] The electric drive cooling flow channel 10 is used for cooling the driving motor, the cockpit heat flow channel 20 is used for heating or cooling the cockpit, and the battery cooling flow channel 30 is used for cooling the battery. The coupling of the three pipelines can supply the heat taken away by the electric drive cooling liquid to the cockpit for heating, and can also guide the heat of the battery into the electric drive cooling flow channel 10 and then discharge.

[0060] In the embodiment, the "selectively communicated" means that by controlling the valve of the first electromagnetic valve, the corresponding circuit can be coupled or disconnected. The integrated molding is preferably cast integrated molding.

[0061] Further, the flow channel plate assembly comprises: a second plate layer 3, the second plate layer 3 is located at the bottom of the first plate layer 1, the upstream end of the second plate layer 3 is communicated with the first plate layer 1, and the downstream end of the second plate layer 3 is re-communicated with the first plate layer 1 through the heat exchange assembly 40.

[0062] The second plate layer 3 can be integrated with the first plate layer 1. The second plate layer 3 is arranged at the bottom of the first plate layer 1, which can realize the exchange of Z-direction space for X and Y-direction space, so that the flow channel plate system is convenient to arrange on the whole vehicle. Figure 3 and Figure 4 As shown in the heat management system, part of it is located inside the longitudinal beam, and the other part is located outside the longitudinal beam. Such arrangement can maximize the convenience of maintenance, reduce the use of pipelines, and reduce the difficulty of whole vehicle arrangement.

[0063] Optionally, the upstream end of the second plate layer 3 is communicated with the first plate layer 1 through a water pump, and the downstream end of the second plate layer 3 is re-communicated with the first plate layer 1 through the heat exchange assembly 40. The water pump pumps the fluid in the first plate layer 1 to the second plate layer 3 and then to the heat exchange assembly 40 for heat exchange and then returns to the first plate layer 1.

[0064] The heat exchange assembly 40 includes a condenser 41 (wcc) and an evaporator 42 (chiller), and the heat exchange assembly (chiller and wcc) is introduced through the second flow channel plate to control the heat of the fluid in the first flow channel plate. The condenser 41 and the evaporator 42 are similar to the condenser / evaporator in the air conditioner, and a closed loop is formed between the condenser 41 and the evaporator 42, and a compressor is arranged on the loop, which is used to compress the fluid in the closed loop to a high-pressure high-temperature state. The refrigerant in the closed loop constantly changes phase to realize the flow of heat. Unlike the air conditioner, the air conditioner is used for heat exchange with the air flow, and the system is used for heat exchange with the fluid to take away the heat of the fluid. As shown in Figure 1 Further, the electrically driven cooling flow channel 10 includes a condenser return water circuit 12, an evaporator return water circuit 11, a first water pump liquid supply circuit 13, and a second water pump liquid supply circuit 14. The heat exchange assembly 40 includes a condenser 41 and an evaporator 42. The upstream end of the second plate layer 3 has a first water pump liquid inlet 31 and a second water pump liquid inlet 32. The downstream end of the second plate layer 3 has a first liquid outlet 33 and a second liquid outlet 34. The first water pump liquid supply circuit 13 is in communication with the first water pump liquid inlet 31 through the first water pump 50. The first water pump liquid inlet 31 is in communication with the first liquid outlet 33. The first liquid outlet 33 is in communication with the condenser return water circuit 12 through the condenser 41. The second water pump liquid supply circuit 14 is in communication with the second water pump liquid inlet 32 through the second water pump 60. The second water pump liquid inlet 32 is in communication with the second liquid outlet 34. The second liquid outlet 34 is in communication with the evaporator return water circuit 11 through the evaporator 42. The cooling path of the fluid is: the first flow channel plate - the first water pump liquid supply circuit 13 - the first water pump 50 - the first water pump liquid inlet 31 - the first liquid outlet 33 - the condenser 41 - the condenser return water circuit 12 - back to the first flow channel plate. The first flow channel plate - the second water pump liquid supply circuit 14 - the second water pump 60 - the second water pump liquid inlet 32 - the second liquid outlet 34 - the evaporator 42 - the evaporator return water circuit 11 - back to the first flow channel plate. Among them, a closed loop is formed between the condenser 41 and the evaporator 42, and a compressor is arranged on the loop. Through the above pipeline design scheme, the heat pipeline path between the electrically driven cooling flow channel 10 and the condenser 41 and the evaporator 42 is realized.

[0065] The one-piece design reduces the connection points between multiple independent pipelines, thereby reducing the potential leakage points of the system during long-term use and improving the reliability of the system.

[0066] Through the arrangement of the condenser 41 and the evaporator 42 and the cooperation of the first water pump 50 and the second water pump 60, the circulation path of the cooling liquid is optimized, so that the cooling liquid can efficiently exchange heat and improve the cooling efficiency.

[0067] The six-way valve provides flexible fluid control, so that the system can selectively connect different pipelines according to different operating states of the vehicle (such as the need for heating or cooling in the cabin, additional cooling of the battery, etc.), achieving precise thermal management.

[0068] Compared with the distributed design, the integrated design can better utilize the internal space of the vehicle, reduce the length of the pipeline, and thus reduce the material cost and assembly cost.

[0069] Through timely heat redistribution, such as using the heat generated by the electric drive for heating the cabin, or providing the battery cooling with the cold energy that the cabin does not need, the energy utilization efficiency of the vehicle is improved, which helps to save energy and reduce emissions.

[0070] Optionally, by integrating temperature sensors and flow sensors, and an intelligent control unit, the fluid temperature and flow of each pipeline can be monitored in real time, and the state of the electromagnetic valve can be automatically adjusted according to the real-time state of the vehicle and the external environment, achieving more intelligent thermal management.

[0071] When designing the fluid channel, a more optimized geometry can be considered, such as increasing the curvature of the flow channel or introducing microchannels, to improve the heat exchange efficiency of the fluid in the pipeline, while reducing the fluid resistance and improving the efficiency of the pump.

[0072] The first plate layer 1 has a backup cooling path, for example, when the main cooling path (such as the condenser 41) fails, the backup cooling path can be activated to ensure the normal operation of the key components (such as the electric drive and the battery).

[0073] Further, the first electromagnetic valve 2 is a six-way valve, and any port of the six-way valve is only connected to a corresponding pipeline. The spool of the six-way valve is controllable, and such a configuration can achieve multiple thermal management modes, so that the fluid in the electric drive cooling flow channel 10 can be controlled to go to the heat dissipation branch or the cabin heat flow channel 20, the battery cooling flow channel 30, and thus perform thermal management tasks. The six-way valve has the characteristic of port switching, so that the pipelines corresponding to different ports can be timely coupled and connected.
