[0002] With the development of new energy vehicle thermal management technology, the thermal management system is becoming more and more complex. In order to simplify the overall vehicle layout, the cooling liquid side is usually integrated, or the cooling liquid side and the refrigerant side are integrated together to reduce the number of pipeline layout and valve pieces and save layout space.

[0003] The way of only integrating the cooling liquid side still has the problems of too many parts and high layout difficulty.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0059] Example 1

[0060] This embodiment provides a thermal management integrated module, which integrates the coolant side and the refrigerant side. The coolant side and the refrigerant side can be integrated into one body or arranged separately, so that multiple vehicle models can share the thermal management integrated module, reducing development and production costs.

[0061] Specifically, if Figure 1-Figure 5 As shown, the thermal management integrated module includes a coolant side integrated module 100 and a refrigerant side integrated module 200 .

[0062] The cooling liquid side integrated module 100 comprises a cooling liquid base plate 110, and a water pump 120 and a liquid side multi-way valve 130 arranged on a first plate surface of the cooling liquid base plate 110. The cooling liquid base plate 110 is internally provided with a plurality of cooling liquid flow channels, and the water pump 120 and the liquid side multi-way valve 130 are respectively communicated with corresponding cooling liquid flow channels. The refrigerant side integrated module 200 comprises a refrigerant base plate 210, a refrigerant side multi-way valve 220 arranged on a first plate surface of the refrigerant base plate 210, an electronic expansion valve group and an electromagnetic valve 260, and a battery cooler 270, a battery heat exchanger 280 and a gas-liquid separator 290 arranged on a second plate surface of the refrigerant base plate 210. The refrigerant base plate 210 is internally provided with a plurality of refrigerant flow channels, and the refrigerant side multi-way valve 220, the electronic expansion valve group, the electromagnetic valve 260, the refrigerant inlet and the refrigerant outlet of the battery cooler 270, the battery heat exchanger 280 and the gas-liquid separator 290 are respectively communicated with corresponding refrigerant flow channels. In addition, the cooling liquid inlet and the cooling liquid outlet of the battery cooler 270 are communicated with corresponding two cooling liquid flow channels, so as to realize heat exchange between the cooling liquid and the refrigerant.

[0063] As shown in Figure 1 and Figure 2 , the thermal management integrated module can be arranged integrally, and this arrangement is suitable for a pure electric vehicle type with sufficient front cabin space. In this arrangement, the cooling liquid side integrated module 100 and the refrigerant side integrated module 200 can be integrated through the connecting frame 300. Specifically, one end of the connecting frame 300 is detachably connected with the cooling liquid base plate 110, and the other end is detachably connected with the refrigerant base plate 210, which is simple in structure and convenient to install. Alternatively, the connecting frame 300 and the cooling liquid base plate 110, and the connecting frame 300 and the refrigerant base plate 210 can be connected through bolt connection, which is simple in structure, high in connection strength, and convenient to install and detach.

[0064] Alternatively, continuing to refer to Figure 1 and Figure 2 , the connecting frame 300 can be provided with one or multiple. In this embodiment, the connecting frame 300 is provided with two, one of which is arranged at the side of the cooling liquid side integrated module 100 and the refrigerant side integrated module 200, and the other is arranged at the bottom of the cooling liquid side integrated module 100 and the refrigerant side integrated module 200. In other embodiments, the number and arrangement of the connecting frame 300 can also be other, which can be arranged according to actual needs, and the present application does not make specific limitation.

[0065] Optionally, when the coolant-side integrated module 100 and the refrigerant-side integrated module 200 are integrated, the coolant inlet and outlet of the battery cooler 270 can be connected to the corresponding two coolant channels via an adapter plate. Specifically, the adapter plate is provided with two coolant channels, and the coolant inlet and outlet of the battery cooler 270 are respectively plugged into one end of the two coolant channels. The two coolant channels are provided with coolant interfaces, and the two coolant interfaces are respectively plugged into the other ends of the two coolant channels.

[0066] like Figure 3 As shown, the thermal management integrated module can also be arranged separately. This arrangement is suitable for hybrid vehicles with limited front cabin space, where both the coolant-side integrated module 100 and the refrigerant-side integrated module 200 cannot be placed in the vehicle's front cabin. In this arrangement, the coolant inlet and outlet of the battery cooler 270 can be connected to the corresponding two coolant flow channels via pipes 400. This arrangement allows the coolant-side integrated module 100 and the refrigerant-side integrated module 200 to be flexibly arranged according to the vehicle's space, providing high universal adaptability.

[0067] The thermal management integrated module provided in this embodiment integrates the coolant side via a coolant baseplate 110 and a liquid-side multi-way valve 130, and the refrigerant side via a refrigerant baseplate 210 and a refrigerant-side multi-way valve 220. This eliminates the need for piping 400, saving space, and reduces the number of valves, saving costs and layout complexity. Furthermore, the coolant-side integrated module 100 and the refrigerant-side integrated module 200 can be deployed separately or integrated via a connecting frame 300, offering a flexible layout. This makes the thermal management integrated module suitable for both pure electric vehicles with ample front cabin space and hybrid vehicles with limited front cabin space, offering high universality and reducing development and production costs.

[0068] Further, see Figure 1-Figure 3 In this embodiment, the second surface of the coolant substrate 110 is disposed opposite the second surface of the refrigerant substrate 210. Two coolant interfaces are provided on the second surface of the coolant substrate 110, which communicate with the coolant inlet and coolant outlet of the battery heat exchanger 280. With this arrangement, when the coolant-side integrated module 100 and the refrigerant-side integrated module 200 are integrated, the battery cooler 270, the battery heat exchanger 280, and the gas-liquid separator 290 are located between the coolant substrate 110 and the refrigerant substrate 210. This allows the coolant substrate 110 and the refrigerant substrate 210 to protect the battery cooler 270, the battery heat exchanger 280, and the gas-liquid separator 290. Furthermore, the coolant inlet and coolant outlet of the battery heat exchanger 280 can be directly connected to the coolant interfaces, minimizing the communication path. This simplifies the structure of the thermal management integrated module and improves its compactness.

[0069] Further, as shown in Figure 4 and Figure 6 The first plate surface of the cooling liquid substrate 110 is provided with a valve seat 111, and the middle part of the valve seat 111 is provided with a mounting cavity 1111 for mounting the liquid-side multi-way valve 130. A plurality of cooling liquid flow channels are arranged along the circumference of the valve seat 111 and communicate with the mounting cavity 1111. The cooling liquid flow channels are arranged one-to-one with the interfaces of the liquid-side multi-way valve 130. In this way, the plurality of cooling liquid flow channels are arranged around the liquid-side multi-way valve 130, improving the compactness of the cooling liquid side integrated module 100.

[0070] Preferably, among the plurality of cooling liquid flow channels arranged along the circumference of the valve seat 111, two cooling liquid flow channels are arranged in a stacked manner along the thickness direction of the cooling liquid substrate 110. In this way, the thickness direction of the cooling liquid substrate 110 is fully utilized, which is beneficial to reducing the area of the cooling liquid substrate 110.

[0071] It is worth noting that the cooling liquid flow channels arranged in a stacked manner along the thickness direction can be arranged in multiple pairs according to design needs, and the present application does not make specific limitations.

[0072] Further, as shown in Figure 6 and Figure 7 In the present embodiment, the liquid-side multi-way valve 130 is a seven-way valve, and the plurality of cooling liquid flow channels include a first cooling liquid flow channel, a second cooling liquid flow channel, a third cooling liquid flow channel, a fourth cooling liquid flow channel, a fifth cooling liquid flow channel, a sixth cooling liquid flow channel, a seventh cooling liquid flow channel arranged along the circumference of the valve seat 111, and an eighth cooling liquid flow channel and a ninth cooling liquid flow channel arranged on one side of the valve seat 111.

[0073] The one end of the first cooling liquid flow channel is communicated with the first interface a of the seven-way valve, and the other end is communicated with the eighth cooling liquid flow channel. The one end of the second cooling liquid flow channel is communicated with the second interface b of the seven-way valve, and the other end is provided with a first battery interface 112, which is communicated with the liquid outlet of the battery. The one end of the third cooling liquid flow channel is communicated with the third interface c of the seven-way valve, and the other end is provided with a first electric drive interface 113, which is used for being communicated with the liquid inlet of the electric drive. The one end of the fourth cooling liquid flow channel is communicated with the fourth interface d of the seven-way valve, and the other end is provided with a heating water pump interface 114, which is used for being communicated with the outlet of the heating water pump. The one end of the fifth cooling liquid flow channel is communicated with the fifth interface e of the seven-way valve, and the other end is provided with a second battery interface 115, which is used for being communicated with the liquid inlet of the battery. The one end of the sixth cooling liquid flow channel is communicated with the sixth interface f of the seven-way valve, and the other end is communicated with the liquid inlet of the battery cooler 270. The one end of the seventh cooling liquid flow channel is communicated with the seventh interface g of the seven-way valve, and the other end is communicated with the liquid outlet of the battery cooler 270. The one end of the eighth cooling liquid flow channel is communicated with the outlet of the water pump 120, and the other end is provided with a radiator interface 116, which is used for being communicated with the inlet of the radiator. The one end of the ninth cooling liquid flow channel is communicated with the liquid inlet of the water pump 120, and the other end is provided with a second electric drive interface 117, which is used for being communicated with the liquid outlet of the electric drive.

[0074] By setting the liquid side multi-way valve 130 as a seven-way valve, the integration of the cooling liquid side components can be realized through the seven-way valve, which simplifies the structure of the cooling liquid side integrated module 100 and facilitates assembly.

[0075] It is worth noting that the electric drive refers to the motor and its controller.

[0076] It is worth noting that the battery, the electric drive, the heating water pump and the radiator all belong to the components of the thermal management integrated system, and the positions of these components can be flexibly arranged according to the space in the vehicle.

[0077] Optionally, the battery can be communicated with the first battery interface 112 and the second battery interface 115 through a pipeline. The electric drive can also be communicated with the first electric drive interface 113 and the second electric drive interface 117 through a pipeline. The heating water pump can also be communicated with the heating water pump interface 114 through a pipeline. The radiator can also be communicated with the radiator interface 116 through a pipeline.

[0078] Further, continuing to refer to Figure 5 and Figure 8In the embodiment, the refrigerant-side multi-way valve 220 is an eight-way valve, and the first interface a, the second interface b, the third interface c, the fourth interface d and the fifth interface e of the eight-way valve are arranged along the length direction of the eight-way valve. The plurality of refrigerant flow channels include a first refrigerant flow channel, a second refrigerant flow channel, a third refrigerant flow channel, a fourth refrigerant flow channel, a fifth refrigerant flow channel, a sixth refrigerant flow channel, a seventh refrigerant flow channel and an eighth refrigerant flow channel. The electronic expansion valve group includes a first electronic expansion valve 230, a second electronic expansion valve 240 and a third electronic expansion valve 250.

[0079] The first refrigerant flow channel is in communication with the first interface a of the eight-way valve at one end and with the inlet of the gas-liquid separator 290 at the other end. The second refrigerant flow channel is in communication with the second interface b of the eight-way valve at one end and with the first inlet of the battery heat exchanger 280 at the other end. The third refrigerant flow channel is in communication with the third interface c of the eight-way valve at one end and is provided with a first evaporator interface 211 at the other end, the first evaporator interface 211 being used for communication with the inlet of the first evaporator. The third refrigerant flow channel is provided with an electromagnetic valve 260, which is used for controlling the opening and closing of the third refrigerant flow channel. The fourth refrigerant flow channel is in communication with the fourth interface d of the eight-way valve at one end and with the refrigerant inlet of the battery cooler 270 at the other end. The fourth refrigerant flow channel is provided with the first electronic expansion valve 230, which is used for controlling the opening and closing of the fourth refrigerant flow channel. The fifth refrigerant flow channel is in communication with the fifth interface e of the eight-way valve at one end and with the first outlet of the battery heat exchanger 280 at the other end. The sixth refrigerant flow channel is in communication with the third refrigerant flow channel at one end and with the fourth refrigerant flow channel at the other end. The sixth refrigerant flow channel is provided with the second electronic expansion valve 240, which is used for controlling the opening and closing of the sixth refrigerant flow channel.

The sixth interface f of the eight-way valve is used for communication with the inlet of the outdoor heat exchanger. The seventh interface g of the eight-way valve is used for communication with the outlet of the indoor cooler. The eighth interface h of the eight-way valve is used for communication with the outlet of the outdoor heat exchanger.

[0080] By setting the refrigerant-side multi-way valve 220 as an eight-way valve, the integration of the refrigerant-side components can be realized through the eight-way valve, the structure of the refrigerant-side integrated module 200 is simplified, and the assembly is facilitated. Moreover, the eight interfaces of the refrigerant-side eight-way valve can be arranged in two rows, so that the arrangement of the components is more reasonable, and the compactness of the structure of the refrigerant-side integrated module 200 is improved.

[0081] It is worth mentioning that the first evaporator and the second evaporator are both parts of the thermal management system. The positions of these parts can be flexibly arranged according to the space in the vehicle.
