Description

Technical Field

[0001] This invention relates to the field of vehicle thermal management technology, and more specifically, to a flow channel plate assembly and a thermal management system having therein, and a vehicle. Background Technology

[0002] In existing technologies, thermal management components are usually designed independently, each with its own cooling circuit. This leads to the use of a large number of coolant pipes and interfaces, increasing the complexity of the vehicle and the difficulty of assembly. Too many pipes and interfaces increase the fluid resistance of the thermal management system, resulting in reduced cooling efficiency and increased energy consumption. The complex pipe layout makes it easy for errors to occur during assembly, increasing assembly time and cost. The increase in pipes and interfaces directly increases the number of potential leakage points, reducing the reliability of the system.

[0003] There is currently no effective solution to the aforementioned technical problems. Summary of the Invention

[0004] The main objective of this invention is to provide a flow channel plate assembly and a thermal management system and vehicle having the same, in order to solve the problems of large space occupation and low integration of flow channel plates in the prior art.

[0005] To achieve the above objectives, according to one aspect of the present invention, a flow channel plate assembly is provided, comprising: a flow channel plate body extending along the length direction of a vehicle, the flow channel plate body including a plurality of cooling channels for communicating with at least one of an electric drive cooling circuit, a battery cooling circuit, and a cockpit thermal management circuit; the flow channel plate body including a first plate layer and a second plate layer disposed adjacent to each other along the width direction of the vehicle, the first plate layer and the second plate layer respectively facing the two sides of the vehicle, wherein a portion of the cooling channels are disposed on the first plate layer and another portion of the cooling channels are disposed on the second plate layer.

[0006] Furthermore, an avoidance notch is provided on one side of the main body of the flow channel plate.

[0007] Furthermore, adjacent cooling channels are spaced apart.

[0008] Furthermore, the same cooling medium flows through two adjacent cooling channels, and / or, different cooling media flow through two adjacent cooling channels.

[0009] Furthermore, channel interfaces are provided at both ends of the cooling channel, and valve body assemblies are provided on some of the channel interfaces. The valve body assemblies are used to control the connection and / or disconnection between two adjacent cooling channels, and / or, the valve body assemblies are used to control the connection between the cooling channel and the electric drive cooling circuit, the battery cooling circuit, and the cockpit thermal management circuit.

[0010] Furthermore, the flow channel plate assembly also includes multiple sensor assemblies, which are located at the cooling channel and / or at the channel interface. The sensor assemblies are used at least to collect parameter information of the cooling medium.

[0011] Furthermore, the multiple cooling channels include: a first cooling channel, which is disposed on the first plate and one end of which is connected to the water pump; a second cooling channel, which is disposed on the second plate and one end of which is connected to the water chiller; a third cooling channel, which is disposed on the second plate and one end of which is connected to the water plate thermostat; and a fourth cooling channel, which is disposed on the second plate and one end of which is connected to the compressor.

[0012] Furthermore, the other end of the first cooling channel is connected to a heat exchanger, the other end of the second cooling channel is connected to a heat exchanger, and the other end of the third cooling channel is connected to a heat exchanger. The heat exchanger is used to exchange heat between the cooling media in the different cooling channels.

This makes the arrangement of the flow channel plate assembly more reasonable and saves more space. At the same time, cooling channels are provided on both sides of the main body of the flow channel plate. The cooling channels can be connected to the electric drive cooling circuit, the battery cooling circuit, and the cockpit thermal management circuit.

However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of this application is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art. In the drawings, for clarity, the thickness of layers and regions may be exaggerated, and the same reference numerals are used to denote the same devices, and therefore their description will be omitted.

[0022] Combination Figures 1 to 2 As shown, according to a specific embodiment of this application, a flow channel plate assembly is provided.

[0023] Specifically, such as Figure 1 , Figure 2 As shown, the flow channel assembly includes a flow channel body 10, which extends along the length of the vehicle. The flow channel body 10 includes a plurality of cooling channels 11, which are connected to at least one of the electric drive cooling circuit, the battery cooling circuit, and the cockpit thermal management circuit. The flow channel body 10 includes a first plate layer 101 and a second plate layer 102 arranged adjacent to each other along the width of the vehicle. The first plate layer 101 and the second plate layer 102 face the two sides of the vehicle, respectively. A portion of the cooling channels 11 are disposed on the first plate layer 101, and the other portion of the cooling channels 11 are disposed on the second plate layer 102.

[0024] By applying the technical solution of this embodiment, the main body 10 of the flow channel plate is extended along the length direction of the vehicle, which can make full use of the extra space in the length direction of the vehicle and reduce the use of space in the height direction of the vehicle. This makes the arrangement of the main body 10 of the flow channel plate more reasonable and saves more space. At the same time, cooling channels 11 are provided on both sides of the main body 10 of the flow channel plate. The cooling channels 11 can be connected to the electric drive cooling circuit, the battery cooling circuit, and the cockpit thermal management circuit. This allows the electric drive cooling circuit, the battery cooling circuit, and the cockpit thermal management circuit to be integrated on the main body 10 of the flow channel plate, which greatly reduces the number of pipes, reduces the volume of the thermal management system, and shortens the assembly time.

[0025] It should be noted that in this embodiment, the main body 10 of the flow channel plate is disposed between the two longitudinal beams of the vehicle, and the main body 10 of the flow channel plate is disposed close to the engine, so that the main body 10 of the flow channel plate and the cooling circuit can make full use of the space in the length direction of the vehicle. Part of the main body 10 of the flow channel plate extends along the height direction of the vehicle, so that the first plate layer 101 and the second plate layer 102 on both sides of the main body 10 of the flow channel plate are respectively oriented towards the two sides of the vehicle longitudinal beam in the width direction of the vehicle. This ensures that the cooling circuits of the components arranged on the inner and outer sides of the vehicle longitudinal beam have sufficient space to communicate with the cooling channel 11 of the main body 10 of the flow channel plate. At the same time, it allows the components arranged on the inner and outer sides of the vehicle longitudinal beam to be disposed close to the main body 10 of the flow channel plate, making the integration of the flow channel plate assembly higher and greatly reducing the volume of the thermal management system.

[0026] Specifically, such as Figure 1 , Figure 2 As shown, a clearance notch 100 is provided on one side of the flow channel plate body 10. The clearance notch 100 can form a clearance space with the vehicle's longitudinal beams, integrated components on the longitudinal beams, and the external environment. This clearance space can avoid integrated components or pipelines, preventing interference between the flow channel plate body 10 and other structures on the vehicle. This ensures that the installation of the flow channel plate body 10 and the flow of the cooling medium are unobstructed, improving the installation flexibility of the flow channel plate and the overall layout efficiency of the cooling system. This allows the thermal management system to better adapt to the design requirements of different vehicle models. In vehicle designs with limited space or where compatibility with other systems needs to be considered, such as in vehicles with a compact engine compartment layout, the clearance notch 100 ensures that the installation of the flow channel plate will not affect the normal operation of the engine or other important components.

[0027] It should be noted that the size and shape of the clearance notch 100 can be customized according to the interior space of different vehicles. For example, if the main body 10 of the runner plate needs to be installed next to the engine, and the engine has a protruding camshaft cover, then the clearance notch 100 can be designed to match the shape of the cover, so that the main body 10 of the runner plate can fit snugly without interfering with the operating space of the camshaft cover. Similarly, if the main body 10 of the runner plate needs to bypass the reinforcing beams or other structural components on the frame, the clearance notch 100 can be designed as a large notch so that the runner plate assembly can be installed without cutting or modifying the existing vehicle structure. At the same time, the clearance notch 100 also ensures the convenience of installation, removal, and maintenance of the main body 10 of the runner plate, making it easier for workers to access hard-to-reach parts.

[0028] In one embodiment of this application, adjacent cooling channels 11 are spaced apart. By controlling the distance between two cooling channels 11, heat transfer between different cooling circuits can be effectively reduced, preventing the coolant of critical components such as the battery, electric drive, and cab from affecting their respective operating temperatures due to heat exchange. This ensures that each cooling channel 11 can independently and effectively exchange heat, while also helping to reduce fluid resistance, improve cooling efficiency, and enhance the heat exchange efficiency of the thermal management system and the cooling independence of each component, thereby improving the overall thermal management performance of the system. Furthermore, a reasonable distance helps optimize the flow characteristics of the fluid within the cooling channels. If the cooling channels 11 are too densely packed, the fluid may experience unnecessary disturbances between the channels, increasing fluid resistance and reducing cooling efficiency. The distance between the cooling channels 11 also affects the overall structural strength of the flow channel plate body 10. If the channels are too close together, the plate may deform under high temperature or high pressure conditions, affecting the stability and reliability of the cooling system.

[0029] In another embodiment of this application, the same cooling medium flows through two adjacent cooling channels 11, and / or, different cooling media flow through two adjacent cooling channels 11. The flow channel assembly can be used simultaneously with multiple thermal management systems. For example, the flow channel assembly can be configured with dual cooling systems, where different cooling media can be used for heat exchange and thermal management. Therefore, in the multiple cooling channels 11 of the flow channel body 10, adjacent or nearby cooling channels 11 may have the same or different cooling media flowing through them. Through flexible selection and distribution of cooling media, optimization can be performed for the cooling needs of different components. Using the same cooling medium simplifies system design, while using different cooling media improves the targeting and efficiency of thermal management, enhancing the adaptability and efficiency of the thermal management system and better meeting the cooling needs of different components.

[0030] It should be noted that when the same cooling medium flows through adjacent cooling channels 11, this usually means that these channels belong to the same cooling circuit and serve the same or related thermal management needs. For example, all channels in the battery cooling circuit may flow with a mixture of water and ethylene glycol to ensure that the battery pack operates at a consistent temperature. In this design, the cooling medium is evenly distributed in multiple channels, which helps to improve cooling efficiency and temperature consistency and reduce the risk of local overheating. When different cooling media flow through adjacent cooling channels 11, this indicates that the system adopts a multi-loop design to adapt to the specific cooling needs of different components. For example, the battery may need to be cooled with a mixture of water and ethylene glycol, while the electric drive system may be more suitable for using a special oil-based coolant to provide better lubrication and heat transfer performance. This design allows the system to more flexibly cope with the thermal management challenges of different components and ensure that each system operates in the best condition through precise temperature control.

[0031] Furthermore, such as Figure 2 As shown, both ends of the cooling channel 11 are provided with channel interfaces 12. Some of the channel interfaces 12 are equipped with valve assemblies. The valve assemblies are used to control the connection and disconnection between at least two adjacent cooling channels 11, and / or, to control the connection between the cooling channel 11 and the electric drive cooling circuit, battery cooling circuit, and cockpit thermal management circuit. By setting valve assemblies, the flow path of the cooling medium can be precisely controlled, enabling independent control of different cooling circuits. This optimizes the operating efficiency of the thermal management system, improves its flexibility and efficiency, and allows for adjustments to the cooling strategy according to actual needs. In systems requiring dynamic adjustment of the cooling strategy, such as during vehicle operation, the flow direction and flow rate of the cooling medium can be intelligently adjusted based on the actual temperature and heat load of the battery, electric drive, and cockpit to achieve the best cooling effect.

[0032] In this embodiment, the valve body assembly can dynamically open or close the connection between two adjacent cooling channels 11 according to the vehicle's operating status or thermal management requirements. For example, when the cab does not require additional cooling, the cab thermal management circuit can be isolated by closing the relevant valve body, thereby saving energy and concentrating the coolant in the battery or electric drive system, thus improving cooling efficiency. Conversely, when the cab cooling needs to be enhanced, the corresponding valve body can be opened to control the flow of coolant through the cab thermal management circuit or to control the opening and closing of the cooling channel 11 connected to the compressor, providing the required cooling performance.

[0033] In another embodiment of this application, the valve body assembly is also responsible for managing the liquid flow between the cooling channel 11 on the flow channel plate and the electric drive cooling circuit, the battery cooling circuit, and the cockpit thermal management circuit. By intelligently controlling the opening and closing of the valve body, the distribution of the cooling medium among different circuits can be adjusted to achieve on-demand cooling and avoid resource waste. For example, when the electric vehicle is traveling at high speed, the electric drive system generates a lot of heat. At this time, the valve body assembly can prioritize ensuring the flow rate of the electric drive cooling circuit. When the vehicle is traveling at low speed or stationary, the valve body state can be adjusted to enhance the cooling of the battery or the cockpit.

[0034] It should be noted that the heat exchange mode of the thermal management system can also be controlled through the valve body assembly, pump body and control module. For example, in winter, the heat generated by the electric drive system and engine during operation can be controlled by the valve body and provided to the battery cooling system through heat exchanger to heat the battery, improve battery performance and reduce energy waste. When the battery and electronic control unit need to be cooled, the control module controls the valve body assembly to circulate the coolant to the battery cooling circuit for thermal management.

[0035] Furthermore, the flow channel plate assembly also includes multiple sensor assemblies 13, which are disposed at the cooling channel 11 and / or at the channel interface 12. The sensor assemblies 13 are used at least to collect parameter information of the cooling medium. By monitoring the temperature, pressure, flow rate, and other parameters of the cooling medium in real time, data support is provided for the intelligent control of the thermal management system, ensuring that the system operates in optimal condition, improving the intelligent control level and operating efficiency of the thermal management system, and enabling timely response to the thermal management needs of components.

[0036] Optionally, the sensor assembly 13 includes sensors such as a temperature sensor, a pressure sensor, and a flow meter. The temperature sensor can monitor the temperature of the cooling medium in different cooling channels 11 in real time, as well as the temperature in the cooling channels 11 connected to the battery cooling circuit and the electric drive cooling circuit. The pressure sensor can monitor the pressure of the cooling medium inside and outside the cooling channel 11. The pressure change can reflect whether there is a blockage or leakage problem in the cooling channel 11, which helps to identify and eliminate faults and avoid damage to the cooling channel 11. The flow meter can measure the flow rate of the cooling medium, thereby assessing the cooling capacity and facilitating the adjustment of the pump output.

[0037] It should be noted that sensor components 13 can also be installed at the battery and electric drive to monitor the temperature and other status of the battery and electric drive in real time. The sensor components 13 transmit the parameter information of the battery, electric drive and cooling medium to the control module. The control module can analyze and process the data, and then control the valve body assembly and pump body to adjust the connection selection of the cooling channel 11 and the flow state of the cooling medium in the cooling channel 11, so as to maintain the optimal operating state of the system.

[0038] Furthermore, such as Figure 1 , Figure 2 As shown, the multiple cooling channels 11 include a first cooling channel 111, a second cooling channel 112, a third cooling channel 113, and a fourth cooling channel 114. The first cooling channel 111 is disposed on the first plate 101, and one end of the first cooling channel 111 is connected to the water pump; the second cooling channel 112 is disposed on the second plate 102, and one end of the second cooling channel 112 is connected to the water chiller; the third cooling channel 113 is disposed on the second plate 102, and one end of the third cooling channel 113 is connected to the water plate thermostat; the fourth cooling channel 114 is disposed on the second plate 102, and one end of the fourth cooling channel 114 is connected to the compressor. By connecting components with different cooling requirements to different cooling channels 11, independent and optimized cooling of each component can be achieved. At the same time, the different cooling channels 11 are respectively disposed on the double-layer structure of the flow channel plate body 10, reducing the number of pipes and interfaces, reducing system complexity, improving the efficiency and reliability of the thermal management system, meeting the cooling requirements of different components, and reducing assembly difficulty and maintenance costs.

[0039] Specifically, the other end of the first cooling channel 111 is connected to a heat exchanger, the other end of the second cooling channel 112 is connected to a heat exchanger, and the other end of the third cooling channel 113 is connected to a heat exchanger. The heat exchanger is used to exchange heat between the cooling media in the different cooling channels 11. Through heat exchange, the heat in the different cooling channels 11 can be effectively managed, avoiding heat waste. At the same time, the temperature regulation function of the heat exchanger can achieve precise control of the cooling medium temperature, improving the energy utilization efficiency and temperature control accuracy of the thermal management system, and better meeting the cooling needs of different components.

[0040] In this embodiment, a first cooling channel 111 is disposed on a first plate 101. One end of the first cooling channel 111 is connected to a water pump, and the other end is connected to a heat exchanger. The water pump can drive the cooling medium through the first cooling channel 111 into the heat exchanger, thereby delivering the coolant to the vehicle's heat source for heat exchange. A second cooling channel 112 is disposed on a second plate 102. One end of the second cooling channel 112 is connected to a water-cooled unit, and the other end is connected to a heat exchanger. The water-cooled unit can cool the cooling medium through refrigerant circulation. The water-cooled unit is connected to the heat exchanger through the second cooling channel 112. When the temperature of the cooling medium in step 1 is too high, the cooling medium can be transferred to the water-cooled unit for additional cooling to ensure that the system temperature drops rapidly to a safe range. The third cooling channel 113 is set on the second plate 102. One end of the third cooling channel 113 is connected to the water plate thermostat, and the other end is connected to the heat exchanger. The water plate thermostat can accurately control the temperature of the cooling medium. The fourth cooling channel 114 is set on the second plate 102. One end of the fourth cooling channel 114 is connected to the compressor, and the other end is connected to the heat exchanger. The fourth cooling channel 114 can perform heat exchange on the compressor refrigerant to realize the control of the cockpit thermal management circuit.

[0041] According to another specific embodiment of this application, a thermal management system is provided, which includes a flow channel plate assembly, the same as the flow channel plate assembly in the above embodiment. The thermal management system employs a double-layer flow channel plate design, integrating the cooling circuits of key components such as the battery, electric drive, and cab together, significantly reducing the number of cooling channels 11, thereby reducing system complexity and assembly difficulty, and improving assembly efficiency. Simultaneously, by reducing the number of channel interfaces 12, the number of leakage points is directly reduced, improving system reliability and safety, reducing maintenance costs and potential failure rates. The optimized flow channel design effectively reduces system flow resistance, improves the efficiency of the thermal management system, and reduces energy consumption. Furthermore, in the double-layer flow channel plate design, by rationally arranging the flow channel spacing and control strategies, effective heat isolation between different circuits is achieved, ensuring independent and effective cooling of each component, further improving the overall performance of the thermal management system.

[0042] According to another specific embodiment of this application, a vehicle is also provided, which has a thermal management system, the thermal management system described in the above embodiment. Applying the above thermal management system to a vehicle enables more efficient management of the temperature of various components during operation, improving vehicle performance and reliability, reducing energy consumption, and also facilitating vehicle maintenance and upgrades. The vehicle can be various types of commercial vehicles, passenger vehicles, and special-purpose vehicles.

[0043] As can be seen from the above description, the above embodiments have the following beneficial effects: The flow channel plate body 10 integrates the cooling circuits of key components such as the battery, electric drive, and cab through the design of a double-layer flow channel plate, significantly reducing the number of cooling channels 11, thereby reducing system complexity and installation difficulty, and improving assembly efficiency; The reduction of channel interfaces 12 directly reduces the number of leakage points, improves the reliability and safety of the system, and reduces maintenance costs and potential failure rates; The flow channel design can effectively reduce fluid resistance in the system, making the fluid flow more smoothly in the system, improving the efficiency of the thermal management system, and may also reduce energy consumption; In the double-layer flow channel plate design, effective heat insulation measures are adopted, such as reasonably arranging the spacing of the cooling channels 11 or adopting different on / off control strategies for the cooling channels 11, to prevent the mutual influence of heat between different circuits and ensure that each component is cooled independently and effectively.
