Description

Technical Field

[0001] This application relates to the field of automotive thermal management technology, and in particular to a thermal management integrated module. Background Technology

[0002] As the automotive industry moves towards electrification and intelligentization, the complexity of vehicle energy management is gradually increasing, and the requirements for automotive energy management systems are also rising. To more effectively meet the needs of electric vehicles, integrated thermal management systems have become a clear trend.

[0003] For example, Chinese patent application number CN202411743809.3 discloses an integrated module for thermal management of electric vehicles, including a six-way water valve, an expansion tank, a battery cooler, a gas-liquid separator, refrigerant valves, a refrigerant temperature sensor, a refrigerant pressure sensor, a water-side manifold, and a refrigerant manifold.

[0004] Regarding the aforementioned technologies, the inventors believe that the following technical defects exist and require improvement:

[0005] Common thermal management integrated modules typically include an expansion tank, which not only complicates the water piping but also increases the overall size of the module due to the large volume of the expansion tank. Furthermore, since the expansion tank needs to be installed at a high position, the entire thermal management integrated module also needs to be fixed at a relatively high position, resulting in inflexible installation and poor adaptability. Utility Model Content

[0006] This application provides a thermal management integrated module to improve the following technical problems:

[0007] Common thermal management integrated modules typically include an expansion tank, which not only complicates the water piping but also increases the overall size of the module due to the large volume of the expansion tank. Furthermore, since the expansion tank needs to be installed at a high position, the entire thermal management integrated module also needs to be fixed at a relatively high position, resulting in inflexible installation and poor adaptability.

[0008] This application provides a thermal management integrated module, which adopts the following technical solution:

[0009] A thermal management integrated module includes a water-side flow channel plate and a refrigerant-side flow channel plate. The water-side flow channel plate has a first side surface and a second side surface arranged opposite to each other. The refrigerant-side flow channel plate is installed on the first side surface. A plate heat exchanger and a thermal management controller are also installed on the first side surface at a position away from the refrigerant-side flow channel plate. A motor-driven water pump, a battery-driven water pump, a six-way water valve, and multiple water temperature sensors are installed on the second side surface. A kettle interface is also provided on the water-side flow channel plate. The kettle interface is used to connect the water supply pipe of an external expansion kettle. The kettle interface, the motor-driven water pump, the battery-driven water pump, and the six-way water valve are respectively located at the four corners of the water-side flow channel plate.

[0010] In one feasible technical solution of this application, the water-side flow channel plate includes a first plate, an intermediate plate, and a second plate. The intermediate plate is sandwiched between the first plate and the second plate, and the kettle interface is located on the intermediate plate. The first plate, the intermediate plate, and the second plate are fixed together by heat fusion welding. The refrigerant-side flow channel plate, the plate heat exchanger, and the thermal management controller are all installed on the first plate. Multiple water temperature sensors, the motor water pump, the battery water pump, and the six-way water valve are all installed on the second plate.

[0011] In one feasible technical solution of this application, a square mounting grid adapted to the thermal management controller is provided on the first plate, and the square mounting grid has a plurality of adjacent regular hexagonal heat dissipation holes.

[0012] In one feasible technical solution of this application, the kettle interface is integrally formed on the intermediate plate, and the kettle interface is perpendicular to the plane of the intermediate plate.

[0013] In one feasible technical solution of this application, the intermediate plate also has a plurality of first water channels for forming water pipes, and a plurality of grid reinforcement portions are provided on the intermediate plate at positions avoiding the first water channels. The grid reinforcement portions have a plurality of regular hexagonal heat dissipation holes and a plurality of square heat dissipation holes.

[0014] In one feasible technical solution of this application, the side of the intermediate plate is further provided with a plurality of mounting ear plates, and a plurality of reinforcing ribs are further provided between the inner side of the mounting ear plates and the main body of the intermediate plate.

[0015] In one feasible technical solution of this application, the second plate has a plurality of second water channels for forming water pipes. The second plate is also provided with a first mounting seat, a second mounting seat and a water valve mounting seat at a position away from the second water channels. The first mounting seat is used to adapt and install the motor water pump, the second mounting seat is used to adapt and install the battery water pump, and the water valve mounting seat is used to adapt and install the six-way water valve.

[0016] In one feasible technical solution of this application, the second plate also has multiple reinforcing rods, one of which is connected between the first mounting base and the second mounting base, and at least two of which are connected between the first mounting base and the water valve mounting base.

[0017] In one feasible technical solution of this application, the reinforcing rod is provided with a plurality of adjacent heat dissipation and weight reduction holes in the middle.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] The expansion kettle is no longer integrated into the thermal management integrated module. Instead, it is indirectly connected to the kettle interface through the water supply pipe, which greatly reduces the complexity of the water pipeline. Moreover, the thermal management integrated module is also greatly reduced in size without the expansion kettle, making the overall structure more compact and small. Furthermore, freed from the limitations of the expansion kettle, the thermal management integrated module of this application does not need to be installed at a high position, and the installation position does not need to be fixed at a relatively high position, thus making the installation position more flexible and adaptable.

[0038] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0039] This application discloses a thermal management integrated module. (Refer to...) Figure 1-3The thermal management integrated module includes a water-side flow channel plate 1 and a refrigerant-side flow channel plate 2. The water-side flow channel plate 1 has a first side surface and a second side surface arranged opposite to each other. The refrigerant-side flow channel plate 2 is installed on the first side surface. A plate heat exchanger 3 and a thermal management controller 4 are also installed on the first side surface at a position away from the refrigerant-side flow channel plate 2. A motor water pump 5, a battery water pump 6, a six-way water valve 7 and multiple water temperature sensors 9 are installed on the second side surface. A kettle interface 8 is also provided on the water-side flow channel plate 1. The kettle interface 8 is used to connect the water supply pipe of an external expansion kettle. The kettle interface 8, the motor water pump 5, the battery water pump 6 and the six-way water valve 7 are located at the four corners of the water-side flow channel plate 1, respectively.

[0040] In this embodiment, for ease of demolding and manufacturing, the water-side flow channel plate 1 includes a first plate 11, an intermediate plate 12, and a second plate 13. The intermediate plate 12 is sandwiched between the first plate 11 and the second plate 13, and the kettle interface 8 is located on the intermediate plate 12. The first plate 11, the intermediate plate 12, and the second plate 13 are fixed by heat fusion welding. That is, the first plate 11, the intermediate plate 12, and the second plate 13 are all made of PP+GF20 material. The refrigerant-side flow channel plate 2, the plate heat exchanger 3, and the thermal management controller 4 are all installed on the first plate 11. Multiple water temperature sensors 9, motor water pump 5, battery water pump 6, and six-way water valve 7 are all installed on the second plate 13. The refrigerant-side flow channel plate 2 is fixed by bolt locking.

[0041] The first plate 11 is provided with a square mounting grid 111 adapted to the thermal management controller 4. The square mounting grid 111 has multiple adjacent regular hexagonal heat dissipation holes. The kettle interface 8 is integrally formed on the middle plate 12, and the kettle interface 8 is perpendicular to the plane of the middle plate 12. The middle plate 12 also has multiple first water channels 122 for forming water pipes. Multiple grid reinforcement parts 123 are provided on the middle plate 12 at positions avoiding the first water channels 122. The grid reinforcement parts 123 have multiple regular hexagonal heat dissipation holes and multiple square heat dissipation holes.

[0042] The middle plate 12 is also provided with multiple mounting ear plates 124 on its side, and multiple reinforcing rib plates 125 are provided between the inner side of the mounting ear plates 124 and the main body of the middle plate 12.

[0043] The second plate 13 has multiple second water channels 131 for forming water pipes. The second plate 13 also has a first mounting seat 132, a second mounting seat 133 and a water valve mounting seat 134 at a position away from the second water channels 131. The first mounting seat 132 is used to install a motor water pump 5, the second mounting seat 133 is used to install a battery water pump 6, and the water valve mounting seat 134 is used to install a six-way water valve 7. The second plate 13 also has multiple reinforcing rods 135, one of which is connected between the first mounting seat 132 and the second mounting seat 133, and at least two of which are connected between the first mounting seat 132 and the water valve mounting seat 134. The middle of the reinforcing rod 135 is provided with multiple adjacent heat dissipation and weight reduction holes.

[0044] The water-side flow channel plate 1 designed above is not only simple in structure, firmly installed, and has high structural strength, making it not easy to bend or deform, but also has a basically hollow internal structure, making it lightweight and having good heat dissipation, which helps to extend its service life.

[0045] The beneficial technical effects of the thermal management integrated module in this application are roughly as follows:

[0046] The expansion kettle is no longer integrated into the thermal management integrated module. Instead, it is indirectly connected to the kettle interface 8 through the water supply pipe, which greatly reduces the complexity of the water pipeline. Moreover, the thermal management integrated module is also greatly reduced in size without the expansion kettle, making the overall structure more compact and small. Furthermore, it is no longer limited by the expansion kettle. The thermal management integrated module of this application does not need to be installed at a high position, and the installation position does not need to be fixed at a relatively high position, thus making the installation position more flexible and adaptable.

[0047] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
