[0065] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0066] The embodiments of the present invention are further described in detail below with reference to the accompanying drawings.

[0067] like Figure 1-Figure 4 As shown, in a first aspect, the present invention provides a thermal management integrated module substrate, comprising: a cooling liquid connecting plate 1, a first valve island 2 and a second valve island 4.

[0068] The coolant connecting plate 1 is used to connect the battery cooling circuit, the electric drive and electronic control cooling circuit, the water-cooled condenser coolant circuit and the waste heat recovery device coolant circuit with the multi-way valve 3; the first valve island 2 is connected to the coolant connecting plate 1, and is used to connect the outlet of the water-cooled condenser refrigerant pipeline and the external condenser 5 to the inlet of the liquid storage tank 6, and to connect the outlet of the liquid storage tank 6 to the evaporator 7 and the inlet of the waste heat recovery device refrigerant pipeline; the second valve island 4 is connected to the coolant connecting plate 1, and is used to connect the outlet of the compressor 8 to the built-in condenser 9 and the external condenser 5.

[0069] In this solution, the battery cooling circuit, the electric drive and electronic control cooling circuit, the water-cooled condenser coolant circuit and the waste heat recovery device coolant circuit are connected through the coolant connecting plate 1, and the heat exchange in the above-mentioned coolant circuits is realized through the multi-way valve 3. The coolant connecting plate 1 is used to replace the cooling water pipe that serves as a connection, which can reduce the complexity of the pipeline, reduce the problem of the cooling water pipe crossing the cabin, and improve the utilization rate of the cabin space. The length of the connecting pipeline is greatly reduced, and the heat exchange with the environment is reduced, so that the heat loss of the system is reduced, the energy consumption is reduced, and the pipeline cost of the whole vehicle is reduced; in addition, the use of valves is reduced, so the use of brackets can also be reduced to save costs.

[0070] The first valve island 2 and the second valve island 4 are used to connect the air conditioning pipelines, reducing the heat exchange between the long air conditioning pipelines and the air, and reducing energy consumption at the same time. In addition, the first valve island 2 connects the outlet of the water-cooled condenser refrigerant pipeline and the outlet of the vehicle-outside condenser 5 to the inlet of the liquid storage tank 6, and connects the outlet of the liquid storage tank 6 to the inlet of the evaporator 7 and the waste heat recovery device refrigerant pipeline. The second valve island 4 connects the outlet of the compressor 8 to the built-in condenser 9 and the vehicle-outside condenser 5, realizing the partition of the refrigerant low-temperature area and the high-temperature area. The high and low temperature partition design is adopted in design, which reduces the mutual heat exchange between the high and low temperature refrigerants, reduces the heat loss of the system, and reduces energy consumption.

[0071] In addition, in this embodiment, the first valve island 2 and the second valve island 4 are spaced apart to further reduce the mutual heat transfer between high and low temperature refrigerants and reduce energy loss.

[0072] In addition, the coolant connecting plate 1 is used to connect the coolant pipelines, and the first valve island 2 and the second valve island 4 are used to connect the air-conditioning pipelines. The coolant pipelines and the air-conditioning pipelines are all converged at the thermal management integrated module substrate, thereby facilitating the centralized arrangement of sensors and valves and pumps. This can facilitate the arrangement of the control module 10. Arranging the control module 10 on or next to the thermal management integrated module substrate can reduce the length of the sensor signal line and the control signal line, facilitate the arrangement of the sensor signal line and the control signal line, and further improve the utilization of the space.

[0073] like Figure 5-Figure 10As shown, in some optional embodiments, the coolant connecting plate 1 includes: an upper plate 11, an interlayer plate 12 and a lower plate 13.

[0074] Among them, one side of the upper plate 11 is used to install the multi-way valve 3; the interlayer plate 12 is attached to one side of the upper plate 11, and forms a first flow channel cavity 101 and a fifth flow channel cavity 105 connecting the two ends of the electric drive and electric control cooling circuit, and a second flow channel cavity 102 connecting one end of the battery cooling circuit between the upper plate 11; the lower plate 13 is attached to the other side of the interlayer plate 12, and forms a third flow channel cavity 103 and a fourth flow channel cavity 104 connecting the two ends of the waste heat recovery device coolant circuit, a sixth flow channel cavity 106 and a seventh flow channel cavity 107 connecting the two ends of the water-cooled condenser coolant circuit, and an eighth flow channel cavity 108 connecting the other end of the battery cooling circuit between the interlayer plate 12.

[0075] In this embodiment, the coolant connecting plate 1 is designed as a three-layer plate structure including an upper plate 11, an interlayer plate 12 and a lower plate 13, so that a first flow channel cavity 101, a fifth flow channel cavity 105 and a second flow channel cavity 102 are formed between the upper plate 11 and the interlayer plate 12, and a third flow channel cavity 103, a fourth flow channel cavity 104, a sixth flow channel cavity 106, a seventh flow channel cavity 107 and an eighth flow channel cavity 108 are formed between the interlayer plate 12 and the lower plate 13. This is equivalent to using a three-layer plate to realize a two-layer flow channel design space, which can reduce the occupied area of ​​the entire coolant connecting plate 1, make the design of the flow channel cavity simpler, and make the flow channel cavity structure simpler and more convenient to process. In addition, when the two-layer flow channel design space is realized to design the above-mentioned flow channel cavities, each flow channel cavity can have more design space, providing conditions for integrating sensors and valves into the coolant connecting plate 1.

[0076] The material of the upper plate 11, the sandwich plate 12 and the lower plate 13 is PP-GF20, and the upper plate 11, the sandwich plate 12 and the lower plate 13 are formed by infrared welding, wherein the inner flow channel wall thickness is 3 mm, which greatly reduces the heat transfer loss caused by the temperature difference on the coolant side and reduces the energy loss of the coolant.

[0077] In addition, the first flow channel cavity 101, the fifth flow channel cavity 105, the second flow channel cavity 102, the third flow channel cavity 103, the fourth flow channel cavity 104, the sixth flow channel cavity 106, the seventh flow channel cavity 107 and the eighth flow channel cavity 108 are all formed by splicing flow channel grooves arranged on the plates on both sides thereof. The flow channel grooves can be sink grooves directly excavated on the plates, or can be grooves formed by partitions arranged on the plates.

[0078] Preferably, the upper plate 11 is provided with communicating holes which correspond one-to-one with the communicating ports of the multi-way valve 3 and are arranged circumferentially, including in sequence: a first communicating hole ①, which is connected to the first flow channel cavity 101; a second communicating hole ②, which is connected to the second flow channel cavity 102; a fourth communicating hole ④, which is connected to the fourth flow channel cavity 104; a fifth communicating hole ⑤, which is connected to the fifth flow channel cavity 105; a sixth communicating hole ⑥, which is connected to the sixth flow channel cavity 106; a seventh communicating hole ⑦, which is connected to the seventh flow channel cavity 107; an eighth communicating hole ⑧, which is connected to the eighth flow channel cavity 108; and a third communicating hole ③, which is connected to the third flow channel cavity 103.

[0079] In order to realize the switching connection between different coolant circuits through the multi-way valve 3 to correspond to different working conditions, connecting holes corresponding to the connecting ports of the multi-way valve 3 and arranged circumferentially are provided on the upper plate 11. After the multi-way valve 3 is installed on the upper plate 11, the valve core of the multi-way valve 3 is rotated to switch the connection state between the connecting holes, thereby realizing the ability to switch between 5 modes and having the ability of proportional adjustment, which is applicable to many scenarios; the switching time between adjacent modes is ≤2s, which can realize rapid switching between different modes of the heat pump system and reduce the risk of heat conduction caused by untimely switching.

[0080] The valve core of the multi-way valve 3 used includes a first communication port 31, a second communication port 32, a third communication port 33, a fourth communication port 34 and a fifth communication port 35 which are arranged in a circumferential direction in sequence. The first communication port 31, the second communication port 32, the third communication port 33, the fourth communication port 34 and the fifth communication port 35 are all flow chambers separated by a partition. Among them, the second communication port 32 and the fifth communication port 35 are connected to each other, and the communication holes corresponding to the two positions can be connected. The first communication port 31, the third communication port 33 and the fourth communication port 34 can all connect two adjacent communication holes.

[0081] In this example, the cross-sections of the first connecting port 31, the second connecting port 32, the third connecting port 33, the fourth connecting port 34 and the fifth connecting port 35 are all roughly fan-shaped areas, arranged at circumferential intervals, and separated into flow cavities by partitions, and the second connecting port 32 and the fifth connecting port 35 are connected through the middle area.

[0082] See also Figure 6-Figure 12 As shown, preferably, a blocking plate 111 is provided in the middle of the connection between the upper plate 11 and the multi-way valve 3, and all the connecting holes are arranged circumferentially along the blocking plate 111; the interlayer plate 12 is provided with an eighth flow hole corresponding to the blocking plate 111, a fourth flow hole corresponding to the fourth connecting hole ④, a sixth flow hole corresponding to the sixth connecting hole ⑥, a seventh flow hole corresponding to the seventh connecting hole ⑦ and a third flow hole corresponding to the third connecting hole ③, and an eighth connecting cavity connected to the eighth flow hole is also formed between the upper plate 11 and the interlayer plate, and the eighth connecting cavity corresponds to the position of the eighth connecting hole ⑧.

[0083] In this example, a first flow channel cavity 101, a fifth flow channel cavity 105 and a second flow channel cavity 102 are formed between the upper plate 11 and the interlayer plate 12, and directly extend to the corresponding first connecting hole ①, fifth connecting hole ⑤ and second connecting hole ②, so that the first connecting hole ① is connected with the first flow channel cavity 101, the fifth connecting hole ⑤ is connected with the fifth flow channel cavity 105, and the second connecting hole ② is connected with the second flow channel cavity 102.

[0084] Since the third flow channel cavity 103, the fourth flow channel cavity 104, the sixth flow channel cavity 106, the seventh flow channel cavity 107 and the eighth flow channel cavity 108 are located between the sandwich plate 12 and the lower plate 13, they cannot be directly connected to the corresponding third connecting hole ③, the fourth connecting hole ④, the sixth connecting hole ⑥, the seventh connecting hole ⑦ and the eighth connecting hole ⑧, therefore, a fourth flow hole corresponding to the fourth connecting hole ④, a sixth flow hole corresponding to the sixth connecting hole ⑥, a seventh flow hole corresponding to the seventh connecting hole ⑦ and a third flow hole corresponding to the third connecting hole ③ are provided on the sandwich plate 12, so that the third flow channel cavity 103, the fourth flow channel cavity 104, the sixth flow channel cavity 106 and the seventh flow channel cavity 107 are connected to the corresponding connecting holes on the upper plate 11 through the third flow hole, the fourth flow hole, the sixth flow hole and the seventh flow hole. The correspondence between the above-mentioned flow holes and the connecting holes refers to the position correspondence.

[0085] In order to facilitate the connection between the eighth flow channel cavity 108 and its corresponding cooling circuit, the eighth flow channel cavity 108 is arranged between the fourth flow channel cavity 104 and the sixth flow channel cavity 106. However, the eighth connecting hole ⑧ corresponding to the eighth flow channel cavity 108 is located between the third connecting hole ③ and the seventh connecting hole ⑦, and it is impossible to open a flow hole corresponding to the position of the eighth connecting hole ⑧ on the interlayer plate 12.

[0086] In this solution, a blocking plate 111 is provided in the middle of the connection between the upper plate 11 and the multi-way valve 3, and an eighth flow hole corresponding to the blocking plate 111 is provided on the sandwich plate 12, and an eighth connecting cavity connected to the eighth flow hole is also formed between the upper plate 11 and the sandwich plate, and the eighth connecting cavity corresponds to the position of the eighth connecting hole⑧, and the eighth flow hole is connected to the eighth flow channel cavity 108, so that the eighth flow channel cavity 108, the eighth flow hole, and the eighth connecting cavity to the eighth connecting hole⑧ are connected. Through this structural design, the eighth flow channel cavity 108 is set between the sandwich plate 12 and the lower plate 13, and can be relatively flexibly set between the fourth flow channel cavity 104 and the sixth flow channel cavity 106, so that the eighth flow channel cavity 108 is connected to the eighth connecting hole⑧, and the connecting hole with the cooling circuit can be set on the side of the lower plate 13 away from the sandwich plate, which is convenient for the setting of the interface.

[0087] More specifically, the first connecting hole ①, the second connecting hole ②, the fourth connecting hole ④, the fifth connecting hole ⑤, the sixth connecting hole ⑥, the seventh connecting hole ⑦, the eighth connecting hole ⑧ and the third connecting hole ③ arranged along the circumference of the blocking plate 111 are all fan-shaped with the same curvature.

[0088] In some optional embodiments, a ninth flow channel cavity 109 is further provided between the upper plate 11 and the interlayer plate 12, and the ninth flow channel cavity 109 is used to connect between the low-temperature radiator and the electric drive and electronic control cooling circuit in the electric drive and electronic control cooling circuit, and the connecting hole also includes a ninth connecting hole ⑨ connected to the ninth flow channel cavity 109, and the ninth connecting hole ⑨ is located between the fifth connecting hole ⑤ and the sixth connecting hole ⑥.

[0089] In this example, the fifth connection port 205 corresponding to the fifth flow channel cavity 105 is also arranged on the side of the upper plate 11 away from the sandwich plate 12, and is used to connect to the inlet of the low-temperature radiator in the electric drive and electric control cooling circuit.

[0090] The ninth connecting hole ⑨ and the fifth connecting hole ⑤ are located in the same sector and share a sector-shaped area. A ninth connecting port 2091 connected to the water inlet of the electric drive and electronic control cooling pipeline is arranged on the side of the upper plate 11, and a radiator interface 2092 is arranged on the ninth flow channel cavity 109 for connecting to the outlet of the low-temperature radiator in the electric drive and electronic control cooling circuit. The radiator interface 2092 is located on the side of the upper plate 11 away from the sandwich plate 12. Such a design can connect the ninth flow channel cavity 109 between the low-temperature radiator and the electric drive and electronic control cooling pipeline in the electric drive and electronic control cooling circuit.

[0091] The second communication port 32 and the fifth communication port 35 can be selectively connected to the ninth communication hole ⑨ or the fifth communication hole ⑤. The first communication port 31, the third communication port 33 and the fourth communication port 34 can connect the fourth communication hole ④ with the fifth communication hole ⑤ and the ninth communication hole ⑨ together or connect with the ninth communication hole ⑨ alone, or connect the sixth communication hole ⑥ with the fifth communication hole ⑤ and the ninth communication hole ⑨ together or connect with the fifth communication hole ⑤ alone.

[0130] The vehicle adopting this solution integrates multiple parts on the coolant connecting plate 1, which can reduce the use of pipelines and brackets, save the space occupied by the cabin, and save costs.

[0131] Specifically, the use of the coolant connecting plate 1 to replace the cooling water pipe for connection can reduce the complexity of the pipeline, reduce the problem of cooling water pipes crossing the cabin, improve the utilization rate of the cabin space, greatly reduce the length of the connecting pipeline, reduce the heat exchange with the environment, reduce the heat loss of the system, reduce energy consumption, and reduce the pipeline cost of the whole vehicle; in addition, the use of valves is reduced, so the use of brackets can also be reduced to save costs. In addition, the first valve island 2 connects the outlet of the water-cooled condenser refrigerant pipeline and the external condenser 5 to the inlet of the liquid storage tank 6, and connects the outlet of the liquid storage tank 6 to the inlet of the evaporator 7 and the waste heat recovery device refrigerant pipeline. The second valve island 4 connects the outlet of the compressor 8 to the built-in condenser 9 and the external condenser 5, realizing the partition of the low-temperature area and the high-temperature area of ​​the refrigerant. The high and low temperature partition design is adopted in design, which reduces the mutual heat between the high and low temperature refrigerants, reduces the heat loss of the system, and reduces energy consumption.
