[0050] See also Figure 1 to Figure 14 This embodiment provides a thermal management coolant side integrated board, including: a board body 10 and a flow channel group arranged in the board body 10, the board body 10 has a first side and a second side arranged opposite to each other, and the flow channel group includes a plurality of flow channels.

[0051] Among them, the first side is provided with a first interface 11, a second interface 12 and a third interface 13 which are respectively connected to the flow channel group. The first interface 11 is used to connect with the water inlet of the heater core, the second interface 12 is used to connect with the cooling water inlet of the battery pack, and the third interface 13 is used to connect with the cooling water outlet of the battery pack.

[0053] Each interface is provided on both sides of the plate body 10. The plate body 10 integrates the pipeline on the coolant side, and can connect components on the coolant side of thermal management such as water-to-water heat exchangers, liquid pumps, and battery coolers, reducing the installation of pipeline parts, thereby reducing the assembly process and assembly time. At the same time, since the plate body 10 is in a plate shape, it occupies a small space and has a high degree of integration, which is conducive to reducing the volume of components on the coolant side of thermal management.

[0054] In some embodiments, the plate body 10 can be integrally formed by methods such as additive manufacturing, which has the advantages of fast processing speed and no connection gaps. Figure 1 to Figure 14As shown, the plate body 10 includes a main plate and a sub-plate, the first side is the outer side of the main plate, the second side is the outer side of the sub-plate, and the inner side of the main plate and the inner side of the sub-plate are connected to each other to form various flow channels. Specifically, the main plate and the sub-plate can be obtained by industrial processing such as injection molding, and then connected to each other by welding, etc., which has the advantages of low cost and high strength, and is suitable for industrial production.

[0055] At the same time, for new energy vehicles such as plug-in hybrid electric vehicles, the operating temperature of the thermal management coolant side can reach 125°C, so the plate body 10 needs to have high high temperature resistance and welding performance. In this embodiment, the material of the plate body 10 is PA66-GF30, that is, 70% polyhexamethylene adipamide mixed with 30% glass fiber. PA66-GF30 has the advantages of high strength, good thermal stability, and hydrolysis resistance.

[0056] In this embodiment, the plate body 10 has vertical and horizontal directions which are respectively perpendicular to the thickness direction of the plate body 10, and the vertical and horizontal directions are perpendicular to each other. The first interface 11, the second interface 12 and the third interface 13 are close to the upper edge of the plate body 10 in the vertical direction, and are arranged in sequence in the horizontal direction. At the same time, below the first interface 11, the second interface 12 and the third interface 13, the first liquid pump installation position 31, the water-to-water heat exchanger installation position and the battery cooler installation position are also arranged in sequence in the horizontal direction on the first side, and the second liquid pump installation position 32 and the multi-way valve installation position 33 are also arranged in sequence in the horizontal direction on the second side. The first liquid pump installation position 31 is used to install the first liquid pump, the second liquid pump installation position 32 is used to install the second liquid pump, the multi-way valve installation position 33 is used to install the multi-way valve, the water-to-water heat exchanger installation position is used to install the water-to-water heat exchanger, that is, a plate heat exchanger for heat exchange between liquids, and the battery cooler installation position is used to install the battery cooler.

[0057] Among them, the first liquid pump installation position 31 is set close to the first interface 11, the multi-way valve installation position 33 is set corresponding to the second liquid pump installation position 32, the fifth interface 15 and the sixth interface 16 are set corresponding to the water-to-water heat exchanger installation position, and the fourth interface 14 is set to avoid the multi-way valve installation position 33.

[0058] Specifically, Figure 3 and Figure 5 As shown, in this embodiment, a first secondary interface 21, a second secondary interface 22, a third secondary interface 23 and a fourth secondary interface 24 are provided in the installation position of the water-to-water heat exchanger.

[0059] The first secondary interface 21 is used to connect the hot water inlet of the water-to-water heat exchanger, the second secondary interface 22 is used to connect the cold water outlet of the water-to-water heat exchanger, the third secondary interface 23 is used to connect the cold water inlet of the water-to-water heat exchanger, and the fourth secondary interface 24 is connected to the hot water outlet of the water-to-water heat exchanger.

[0060] Among them, the first secondary interface 21 is arranged corresponding to the fifth interface 15, so that the first secondary interface 21 is directly connected to the fifth interface 15. The second secondary interface 22 is arranged near the second interface 12 relative to the third secondary interface 23 and the fourth secondary interface 24, so as to arrange the flow channel between the second secondary interface 22 and the second interface 12. At the same time, since the battery cooler mounting position and the multi-way valve mounting position 33 are arranged near the lower edge of the board body 10, the third secondary interface 23 and the fourth secondary interface 24 are arranged near the lower edge of the board body 10 relative to the first secondary interface 21 and the second secondary interface 22 in the vertical direction in this embodiment, and the third secondary interface 23 is arranged near the battery cooler mounting position, and the fourth secondary interface 24 is arranged near the multi-way valve mounting position 33, so as to arrange the flow channel between the third secondary interface 23 and the battery cooler mounting position, and the flow channel between the fourth secondary interface 24 and the multi-way valve mounting position 33.

[0061] Specifically, in this embodiment, a fifth secondary interface 25 and a sixth secondary interface 26 are provided in the battery cooler installation position, the fifth secondary interface 25 is used to connect the outlet of the battery cooler, and the sixth secondary interface 26 is used to connect the inlet of the battery cooler. The fifth secondary interface 25 is provided near the water-to-water heat exchanger installation position, so as to facilitate the layout of the flow channel between the fifth secondary interface 25 and the water-to-water heat exchanger installation position, specifically, to facilitate the layout of the flow channel between the fifth secondary interface 25 and the third secondary interface 23. At the same time, the sixth secondary interface 26 is provided near the second liquid pump installation position 32 relative to the fifth secondary interface 25, so as to facilitate the layout of the flow channel between the sixth secondary interface 26 and the second liquid pump installation position 32.

[0062] Specifically, Figures 5 to 14 As shown, in this embodiment, the multi-way valve installation position 33 is provided with a first communication interface 331, a second communication interface 332, a third communication interface 333 and a fourth communication interface 334. The flow channel group includes a first flow channel 1, a second flow channel 2, a third flow channel 3 and a fourth flow channel 4.

[0063] The first flow channel 1 is connected to the first communication interface 331 and the sixth interface 16 respectively. When the sixth interface 16 is connected to the water inlet of the heater core, the coolant in the first flow channel 1 can flow from the first communication interface 331 to the sixth interface 16 and finally enter the heater core. In this embodiment, the sixth interface 16 is higher than the first communication interface 331, and the first flow channel 1 adopts a large rounded transition structure, which reduces the flow resistance of the coolant in the first flow channel 1. At the same time, the coolant in the first flow channel 1 flows from bottom to top, which is conducive to the discharge of gas in the coolant.

[0064] The second flow channel 2 is connected to the second communication interface 332 and the fourth secondary interface 24 respectively. When the fourth secondary interface 24 is connected to the hot water outlet of the water-to-water heat exchanger, the hot water discharged from the water-to-water heat exchanger can flow from the fourth secondary interface 24 to the second communication interface 332. In this embodiment, the fourth secondary interface 24 and the second communication interface 332 have substantially the same height in the vertical direction, and the second flow channel 2 adopts a large rounded structure, which reduces the flow resistance of the coolant in the second flow channel 2.

[0065] The third flow channel 3 is connected to the third communication interface 333 and the first interface 11 respectively. When the first interface 11 is connected to the cooling water inlet of the engine, the coolant in the third flow channel 3 can flow from the third communication interface 333 to the first interface 11 to enter the engine. In this embodiment, the first interface 11 and the third communication interface 333 are substantially at the same height in the vertical direction, so as to prevent the coolant in the third flow channel 3 from flowing from top to bottom, thereby reducing the risk of exhaust.

[0066] A first liquid pump inlet 311 and a first liquid pump outlet 312 are provided in the first liquid pump installation position 31. The first liquid pump inlet 311 is provided corresponding to the fourth connecting interface 334 and is connected to the fourth connecting interface 334. The fourth flow channel 4 is respectively connected to the first liquid pump outlet 312 and the fourth interface 14. When the first liquid pump is installed on the first liquid pump installation position 31, a multi-way valve is installed on the multi-way valve installation position 33, and the fourth interface 14 is connected to the inlet of the water heater, the first liquid pump inlet 311 of the first liquid pump can absorb coolant from the fourth connecting interface 334 of the multi-way valve, and drive the coolant to enter the fourth flow channel 4 from the first liquid pump outlet 312, and enter the water heater from the fourth interface 14 along the fourth flow channel 4 to heat the coolant.

[0067] Specifically, in this embodiment, the cross-sectional area of ​​the fourth flow channel 4 gradually increases from the first liquid pump outlet 312 to the fourth interface 14, that is, the cross-sectional area of ​​the fourth flow channel 4 gradually expands from the inlet to the outlet, so as to avoid an increase in the flow resistance of the fourth flow channel 4 due to a sudden change in the cross-sectional area of ​​the fourth flow channel 4.

[0068] In this embodiment, the flow channel group also includes a fifth flow channel 5, and the fifth flow channel 5 is connected to the second interface 12 and the second secondary interface 22 respectively. When a water-to-water heat exchanger is installed at the water-to-water heat exchanger mounting position, and the second interface 12 is connected to the cooling water inlet of the battery pack, the cold water discharged from the water-to-water heat exchanger can enter the fifth flow channel 5 through the second secondary interface 22, and flow out of the second interface 12 from the fifth flow channel 5, and finally flow into the cooling water inlet of the battery pack to cool the battery pack. In this embodiment, the second interface 12 is higher than the second secondary interface 22, and the fifth flow channel 5 adopts a large fillet transition structure to reduce the flow resistance of the fifth flow channel 5 and optimize the exhaust of the fifth flow channel 5.

[0069] In this embodiment, the flow channel group includes a sixth flow channel 6 and a seventh flow channel 7. A second liquid pump inlet 321 and a second liquid pump outlet 322 are provided in the second liquid pump installation position 32. The sixth flow channel 6 is respectively connected to the third interface 13 and the second liquid pump inlet 321, and the seventh flow channel 7 is respectively connected to the second liquid pump outlet 322 and the sixth secondary interface 26.

[0070] When a second liquid pump is installed on the second liquid pump mounting position 32, and the third interface 13 is connected to the cooling water outlet of the battery pack, and the sixth secondary interface 26 is connected to the inlet of the battery cooler, the cooling water discharged from the battery pack that absorbs the heat of the battery can enter the second liquid pump inlet 321 through the sixth flow channel 6, and then, under the action of the second liquid pump inlet 321, enters the inlet of the battery cooler through the seventh flow channel 7 to cool the coolant.

[0071] In this embodiment, the cross-sectional area of ​​the seventh flow channel 7 gradually increases from the second liquid pump outlet 322 to the sixth secondary interface, that is, the cross-sectional area of ​​the seventh flow channel 7 gradually expands from the inlet to the outlet, so as to avoid an increase in the flow resistance of the seventh flow channel 7 due to a sudden change in the cross-sectional area of ​​the seventh flow channel 7.

[0072] In this embodiment, the flow channel group further includes an eighth flow channel 8, which is respectively connected to the third secondary interface 23 and the fifth secondary interface 25. When the third secondary interface 23 is connected to the cold water inlet of the water-to-water heat exchanger and the fifth secondary interface 25 is connected to the outlet of the battery cooler, the coolant flowing through the battery cooler can flow into the cold water inlet of the water-to-water heat exchanger via the eighth flow channel 8.

[0073] In this embodiment, the fifth secondary interface 25 is higher than the third secondary interface 23 in the vertical direction. When the coolant flows through the eighth flow channel 8, it flows from top to bottom, which is convenient for the flow of the coolant and the discharge of the liquid in the coolant.

[0074] In this embodiment, a refilling port 17 for connecting to a water tank is provided on the second side. When the coolant in the coolant side is lacking, the water tank can refill the coolant to the coolant side through the refilling port 17. In this embodiment, the refilling port 17 is higher than the third interface 13 and the second liquid pump inlet 321 in the vertical direction. The sixth flow channel 6 is also connected to the refilling port 17. From the second liquid pump inlet 321 to the refilling port 17, the sixth flow channel 6 rises continuously in the vertical direction. When the coolant in the third interface 13 flows to the second liquid pump inlet 321 via the sixth flow channel 6, the gas contained in the coolant is separated from the coolant under the action of buoyancy. Since the sixth flow channel 6 is connected to the refilling port 17 and from the second liquid pump inlet 321 to the refilling port 17, the sixth flow channel 6 rises continuously in the vertical direction, the separated gas can move to the refilling port 17 via the sixth flow channel 6 and finally be discharged from the refilling port 17, so as to achieve gas-liquid separation, facilitate exhaust, and reduce flow resistance.

[0075] The present embodiment also provides a thermal management coolant side integrated device, comprising an integrated board as described in any of the above items, and also comprising a water-to-water heat exchanger, a liquid pump, a battery cooler and a multi-way valve. The water-to-water heat exchanger, the liquid pump, the battery cooler and the multi-way valve are respectively connected to the integrated board to be finally assembled into a thermal management coolant side integrated device.

[0076] In this embodiment, the top of the plate body is used to install a water tank, and a support foot 40 is provided at the bottom of the plate body. The thermal management coolant side integrated device can be installed on the whole vehicle through the support foot 40. The support foot 40 is integrally formed on the plate body 10 and does not require additional installation or setting, which is beneficial to reducing the number of cold components and installation costs of the thermal management coolant side integrated device.

[0077] In summary, the present embodiment provides a thermal management coolant side integrated plate and a thermal management coolant side integrated device. Since the flow channel group is arranged in the plate body, the plate body has a first side and a second side arranged opposite to each other. The first interface for connecting to the water inlet of the heater core, the second interface for connecting to the cooling water inlet of the battery pack, and the third interface for connecting to the cooling water outlet of the battery pack are arranged on the first side. The second side is provided with a fourth interface, a fifth interface, and a sixth interface respectively connected to the flow channel group. The fourth interface is used to connect to the water inlet of the water heater, the fifth interface is used to connect to the water outlet of the water heater, and the sixth interface is used to connect to the cooling water inlet of the engine, that is, each interface is respectively arranged on both sides of the plate body. The plate body integrates the pipeline on the coolant side, and can connect the components on the thermal management coolant side such as water-to-water heat exchanger, liquid pump, battery cooler, etc., which reduces the installation of pipeline parts, thereby reducing the assembly process and assembly time. At the same time, since the plate body is in the shape of a plate, it occupies a small space and has a high degree of integration, which is conducive to reducing the volume of the components on the thermal management coolant side and improving the space utilization rate of the whole vehicle.

[0078] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention.
