Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides various specific processes and examples of materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.

[0047] Reference below Figure 1-Figure 10 Describe the thermal management integrated module 100 according to an embodiment of the present invention:

[0048] like Figure 1-Figure 9 As shown, the thermal management integrated module 100 according to the embodiment of the present invention includes: a first heat exchanger 20 , a second heat exchanger 30 , a manifold 10 , a water pump assembly 40 and a switching valve assembly 50 .

[0049] The first heat exchanger 20 is provided with a first flow channel and a second flow channel that can exchange heat with each other, and the second heat exchanger 30 is provided with a third flow channel and a fourth flow channel that can exchange heat with each other, the first flow channel and the third flow channel are both connected to the external refrigerant system, the second flow channel is provided with a first inlet 21 and a first outlet 22, and the fourth flow channel is provided with a second inlet 31 and a second outlet 32; a plurality of built-in flow channels are provided in the manifold 10, the first heat exchanger 20 and the second heat exchanger 30 are both provided on the manifold 10, and the first inlet 21 and the second inlet 31 are respectively connected to the outlets of different built-in flow channels, and the first outlet 22 and the second outlet 32 ​​are respectively connected to the inlets of different built-in flow channels; the water pump assembly 40 and the switching valve assembly 50 are both installed on the manifold 10, the water pump assembly 40 is connected between the inlet and the outlet of the built-in flow channel, and the switching valve assembly 50 is used to selectively connect different built-in flow channels.

[0050] Therefore, the first heat exchanger 20, the second heat exchanger 30, the water pump assembly 40 and the switching valve assembly 50 are all integrated on the manifold 10, so that when the manifold 10 is assembled to the vehicle 1000, the remaining parts of the thermal management integrated module 100 are already integrated, which makes the assembly process simpler, thereby improving the assembly efficiency. At the same time, since the remaining parts are already integrated on the manifold 10, the overall weight of the thermal management integrated module 100 can also be reduced.

[0051] For example, the busbar 10 can be formed by hot plate welding of 2-3 layers of molded plastic plates containing built-in flow channels. A number of water pipe interfaces are provided on the busbar 10, which are connected to the system through pipelines. At the same time, there are a number of brackets on the busbar 10, and vibration damping pads and metal bushings are installed on the brackets. The busbar 10 is installed on the vehicle 1000 through the brackets, and the first heat exchanger 20 and the second heat exchanger 30 can be plate heat exchangers, both of which are installed on the busbar 10, and a battery cooling electronic expansion valve is provided in the external refrigeration system connected to the third flow channel of the second heat exchanger 30. The built-in flow channel enables the cooling medium to flow directly in the built-in flow channel when the vehicle 1000 cools or heats components such as the battery pack 60 and the electric drive assembly 70, so that the risk of leakage of the cooling medium when flowing in the built-in flow channel is lower, and there is no need to arrange too many pipes in the vehicle 1000, thereby saving internal installation space for the vehicle 1000.

[0052] According to the thermal management integrated module 100 of the embodiment of the present invention, the first heat exchanger 20, the second heat exchanger 30, the water pump assembly 40 and the switching valve assembly 50 are all integrated on the manifold 10 and selectively connected through the built-in flow channels of the manifold 10. In this way, the arrangement of external pipelines can be reduced, thereby simplifying the assembly process of the thermal management integrated module 100, and facilitating the reduction of the weight of the thermal management integrated module 100, which is conducive to realizing its lightweight design. At the same time, the switching valve assembly 50 can selectively connect different built-in flow channels to realize multiple working modes of the thermal management system.

[0053] In some embodiments, Figure 1-Figure 9 As shown, the busbar 10 is provided with a battery pack cooling inlet 112, a battery pack cooling outlet 113, an electric drive cooling inlet 114 and an electric drive cooling outlet 115. The battery pack cooling inlet 112 and the battery pack cooling outlet 113 are respectively connected to the outlet and inlet of the cooling circuit of the battery pack, and the battery pack cooling inlet 112 and the battery pack cooling outlet 113 are connected through a built-in flow channel. The electric drive cooling inlet 114 and the electric drive cooling outlet 115 are respectively connected to the outlet and inlet of the cooling circuit of the electric drive assembly 70, and the electric drive cooling inlet 114 and the electric drive cooling outlet 115 are connected through a built-in flow channel.

[0054] Therefore, when the battery pack 60 and the electric drive assembly 70 are cooled, the cooling medium can flow from the inlet of the busbar 10 into the inlet of the cooling circuit of the battery pack 60 and the electric drive assembly, and the cooling outlet and the cooling inlet of the battery pack 60 and the electric drive assembly 70 are connected through the built-in flow channel, thus forming a complete flow channel, so that the battery pack 60 and the electric drive assembly 70 will not be short-circuited during cooling.

[0055] In some embodiments, Figure 1-Figure 5 As shown, the multiple built-in flow channels include a first built-in flow channel 101, a second built-in flow channel 102, a third built-in flow channel 103, a fourth built-in flow channel 104, a fifth built-in flow channel 105, a sixth built-in flow channel 106, a seventh built-in flow channel 107, an eighth built-in flow channel 108, a ninth built-in flow channel 109 and a tenth built-in flow channel 110; the switching valve assembly 50 includes a nine-way valve 51 and a five-way valve 52, the nine-way valve 51 is provided with a plurality of valve ports, the plurality of valve ports include a first valve port 511, a second valve port 512, a third valve port 513, a fourth valve port 514, a fifth valve port 515, a sixth valve port 516, a seventh valve port 517 and an eighth valve port 518, the five-way valve 52 is provided with a plurality of sub-valve ports, the plurality of sub-valve ports include a first sub-valve port 521, a second sub-valve port 522, a third sub-valve port 523 and a fourth sub-valve port 524, and the two built-in flow channels are connected through two valve ports and / or two sub-valve ports.

[0056] Thus, multiple built-in flow channels are connected through the valve port of the nine-way valve 51, so that two built-in flow channels can be connected together through the nine-way valve 51 to form a complete circuit, or the two built-in flow channels can also be connected together through the two sub-valve ports of the five-way valve 52 to form a complete circuit, or the built-in flow channels can be connected through the valve port of the nine-way valve 51 and the sub-valve port of the five-way valve 52. For example, in this embodiment, the built-in flow channels can be connected through the valve port of the nine-way valve 51 and the sub-valve port of the five-way valve 52, specifically, the two built-in flow channels are connected through two valve ports or two sub-valve ports.

[0057] In some embodiments, Figure 1-Figure 2 As shown, the water pump assembly 40 includes a battery water pump 42. In the battery pack refrigeration circuit, the battery pack cooling inlet 112 is connected to the outlet of the battery pack cooling circuit, the first built-in flow channel 101 is connected between the battery pack cooling inlet 112 and the first valve port 511, the first valve port 511 and the second valve port 512 are connected, the second built-in flow channel 102 is connected between the second valve port 512 and the second inlet 31, the battery water pump 42 is arranged in the second built-in flow channel 102, the third built-in flow channel 103 is connected between the second outlet 32 ​​and the fourth valve port 514, the third valve port 513 and the fourth valve port 514 are connected, the fourth built-in flow channel 104 is connected between the third valve port 513 and the battery pack cooling outlet 113, and the battery pack cooling outlet 113 is connected to the inlet of the battery pack cooling circuit.

[0058] Specifically, when the thermal integration module is in the cooling mode, there are multiple refrigeration circuits. In the battery pack refrigeration circuit, the cooling medium moves from the battery water pump 42 in the second built-in flow channel 102 toward the second inlet 31 under the action of the battery water pump 42, and enters the third built-in flow channel 103 through the second outlet 32 ​​after releasing heat in the second heat exchanger 30. At this time, the fourth valve port 514 will be connected with the third valve port 513, and the cooling medium enters the fourth built-in flow channel 104 through the fourth valve port 514 and the third valve port 513, and then enters the battery pack cooling outlet 113 and then enters the battery pack cooling circuit. After cooling the battery pack 60, it enters the first built-in flow channel 101 through the battery pack cooling inlet 112. At this time, the first valve port 511 is connected with the second valve port 512, and the cooling medium can enter the second built-in flow channel 102 through the first valve port 511 and the second valve port 512, so that the cooling medium can be driven by the battery water pump 42 to exchange heat again.

[0059] It should be noted that the battery pack refrigeration circuit in this embodiment is a circuit existing in the busbar 10, while the battery pack cooling circuit does not exist in the busbar 10. Therefore, in the fourth built-in circuit, the cooling medium first enters the battery pack cooling circuit through the battery pack cooling outlet 113 of the fourth built-in circuit after passing through the check valve, and then enters the first built-in circuit through the battery pack cooling inlet 112 after cooling the battery pack 60.

[0060] Therefore, the battery water pump 42 is arranged in the battery pack refrigeration circuit, so that when the battery pack 60 is cooled, the battery water pump 42 can provide power for the cooling medium in the refrigeration circuit, so that the cooling medium has sufficient power to move in the battery pack refrigeration circuit, thereby better cooling the battery pack 60.

[0061] In some embodiments, Figure 1-Figure 2 As shown, the water pump assembly 40 also includes an electric-driven water pump 41. In the refrigeration circuit of the electric-driven assembly, the electric-driven cooling inlet 114 is connected to the outlet of the cooling circuit of the electric-driven assembly, the fifth built-in flow channel 105 is connected between the electric-driven cooling inlet 114 and the fifth valve port 515, the fifth valve port 515 is connected to the sixth valve port 516, the sixth built-in flow channel 106 is connected between the sixth valve port 516 and the seventh valve port 517, and the sixth built-in flow channel 106 is connected to the external heat dissipation pipeline 80, and a radiator is provided on the external heat dissipation pipeline 80, the seventh valve port 517 is connected to the eighth valve port 518, the seventh built-in flow channel 107 is connected between the eighth valve port 518 and the electric-driven cooling outlet 115, the electric-driven water pump 41 is provided in the seventh built-in flow channel 107, and the electric-driven cooling outlet 115 is connected to the inlet of the cooling circuit of the electric-driven assembly.

[0062] Specifically, when the thermal management integrated module 100 is in the cooling mode, there is also a cooling circuit of the electric drive component, in which an electric drive water pump 41 is provided. The electric drive water pump 41 drives the cooling medium to move in the seventh built-in flow channel 107 toward the electric drive component 70, and enters the cooling circuit of the electric drive component 70 after passing through the electric drive cooling outlet 115. After the cooling medium cools the electric drive component 70, it enters the fifth built-in flow channel 105 from the electric drive cooling inlet 114. At this time, the fifth valve port 515 is connected to the sixth valve port 515. The valve port 516 is connected, and the cooling medium enters the sixth built-in flow channel 106 after passing through the fifth valve port 515 and the sixth valve port 516. The sixth built-in flow channel 106 is connected with an external heat dissipation pipeline 80. The cooling medium can dissipate heat in the external radiator before entering the sixth built-in flow channel 106. At this time, the seventh valve port 517 is connected with the eighth valve port 518, and the cooling medium enters the seventh built-in flow channel 107 through the seventh valve port 517 and the eighth valve port 518, so that the cooling medium is driven by the electric water pump 41 again.

[0063] It should be noted that in the refrigeration circuit of the electric drive component, there is also a flow path flowing to the five-way valve 52. In this flow path, the cooling medium moves in the seventh built-in flow channel 107 toward the fifth sub-valve port 525 under the action of the electric drive water pump 41. At this time, the fifth sub-valve port 525 is connected to the first sub-valve port 521. After passing through the fifth sub-valve port 525 and the first sub-valve port 521, the cooling medium will enter the eighth built-in flow channel 108, wherein the eighth built-in flow channel 108 is also provided with a heating water pump 43, and the cooling medium The medium in the eighth built-in flow channel 108 will move toward the first inlet 21 driven by the heating water pump 43 and enter the first heat exchanger 20 for heat exchange. After the heat exchange is completed, it will enter the eleventh built-in flow channel 111. At this time, the ninth valve port 519 will be connected to the sixth valve port 516. After passing through the ninth valve port 519 and the sixth valve port 516, the cooling medium can enter the sixth built-in flow channel 106. At this time, the movement path of the cooling medium is consistent with the path of flowing through the nine-way valve 51 in the above embodiment, which will not be repeated here.

[0064] Therefore, the electric water pump 41 is arranged in the refrigeration circuit of the electric drive component. When cooling the electric drive component 70, the electric water pump 41 can provide sufficient power for the cooling medium in the refrigeration circuit of the electric drive component, so that the cooling medium has sufficient power to flow when circulating in the refrigeration circuit. At the same time, the cooling medium can exchange heat in the external heat exchanger and the first heat exchanger 20, which can enable the cooling medium to obtain a good heat exchange effect, thereby better cooling the electric drive component 70.

[0065] In some embodiments, Figure 1 and Figure 3As shown, the water pump assembly 40 also includes a heating water pump 43. In the electric drive waste heat recovery circuit, the eighth built-in flow channel 108 is connected between the first sub-valve port 521 and the first inlet 21. The heating water pump 43 is arranged in the eighth built-in flow channel 108. The first outlet 22 is connected to the inlet of the warm air circuit of the vehicle 1000. The outlet of the warm air circuit is connected to the second sub-valve port 522, and the second sub-valve port 522 is connected to the first sub-valve port 521.

[0066] Specifically, the thermal management integrated module 100 also has a battery cold storage and dehumidification waste heat recovery mode. In this mode, the electric drive waste heat recovery circuit in the busbar 10 can be divided into an external circuit and an internal circuit. In the external circuit, the heating water pump 43 located in the eighth built-in flow channel 108 drives the cooling medium to move toward the first inlet 21 of the first heat exchanger 20. After heat exchange through the first heat exchanger 20, the cooling medium enters the warm air circuit of the vehicle 1000 from the first outlet 22. There are PTC and warm air core in the warm air circuit of the vehicle 1000. When the cooling medium flows through the PTC and the warm air core, it can provide warm air to the cockpit of the vehicle 1000. The outlet of the warm air circuit is connected to the second sub-valve port 522 and the second sub-valve port 522 is connected to the first sub-valve port 521. In this way, after flowing out of the warm air circuit, the cooling medium passes through the second sub-valve port 522 and the first sub-valve port 521 into the eighth built-in flow channel 108, so that it can be driven by the heating water pump 43 again.

[0067] Therefore, the heating water pump 43 is arranged in the eighth built-in flow channel 108. When the thermal management integrated module 100 is in the battery cooling and dehumidification waste heat recovery mode, the cooling medium can enter the warm air circuit of the vehicle 1000 to provide warm air for the cockpit of the vehicle 1000.

[0068] In some embodiments, Figure 1 and Figure 3 As shown, in the battery waste heat recovery circuit, the second valve port 512 is connected to the second inlet 31 through the second built-in flow channel 102, the second outlet 32 ​​is connected to the fourth valve port 514 through the third built-in flow channel 103, the fourth valve port 514 is connected to the third valve port 513, the third valve port 513 is connected to the battery pack cooling outlet 113 through the fourth built-in flow channel 104, the battery pack cooling inlet 112 is connected to the first valve port 511 through the first built-in flow channel 101, the first valve port 511 is connected to the eighth valve port 518, the eighth valve port 518 is connected to the electric drive cooling outlet 115 through the seventh built-in flow channel 107, the electric drive cooling inlet 114 is connected to the fifth valve port 515 through the fifth built-in flow channel 105, and the fifth valve port 515 is connected to the second valve port 512.

[0069] Specifically, in the internal loop of the battery waste heat recovery loop, the battery water pump 42 drives the cooling medium to move toward the second heat exchanger 30. After completing heat exchange in the second heat exchanger 30, the cooling medium enters the third built-in flow channel 103, and then enters the fourth built-in flow channel 104 through the fourth valve port 514 and the third valve port 513, and then enters the battery pack cooling loop. After absorbing heat, it passes through the first valve port 511 and the eighth valve port 518 to enter the seventh built-in flow channel 107, and then moves toward the electric drive component 70 driven by the electric drive water pump 41 in the seventh built-in flow channel 107, thereby entering the cooling loop of the electric drive component. After completing heat absorption of the electric drive component 70, the cooling medium enters the fifth built-in flow channel 105 through the electric drive cooling inlet 114, and then passes through the fifth valve port 515 and the third valve port 513 to enter the second built-in flow channel 102, so that it can be driven by the battery water pump 42 again.

[0070] Therefore, in the internal circuit of battery waste heat recovery, the battery water pump 42 can drive the cooling medium to absorb heat from the battery pack 60, and after the heat absorption is completed, it can enter the seventh built-in flow channel 107 and then be driven by the electric drive water pump 41 to absorb heat from the electric drive component 70, and finally enter the side of the battery water pump 42. In this way, waste heat can be utilized for both the battery pack 60 and the electric drive component 70, thereby making the heat absorption efficiency higher.

[0071] In some embodiments, Figure 1 and Figure 4 As shown, in the battery electric drive cooling circuit, the eighth valve port 518 is connected to the electric drive cooling outlet 115 through the seventh built-in flow channel 107, the electric drive cooling inlet 114 is connected to the fifth valve port 515 through the fifth built-in flow channel 105, the fifth valve port 515 is connected to the sixth valve port 516, the sixth valve port 516 is connected to the seventh valve port 517 through the sixth built-in flow channel 106 and the external heat dissipation pipeline 80, the seventh valve port 517 is connected to the third valve port 513, the third valve port 513 is connected to the battery pack cooling outlet 113 through the fourth built-in flow channel 104, the battery pack cooling inlet 112 is connected to the first valve port 511 through the first built-in flow channel 101, and the first valve port 511 is connected to the eighth valve port 518.

[0072] Specifically, the thermal management integrated module 100 also includes a battery electric drive cooling mode. In the battery electric drive cooling circuit, the cooling medium in the seventh built-in flow channel 107 moves toward the electric drive component 70 through the electric drive water pump 41, and enters the cooling circuit of the electric drive component through the electric drive cooling outlet 115 to cool the electric drive component 70. After cooling, the cooling medium enters the fifth built-in flow channel 105 through the electric drive cooling inlet 114, and then enters the sixth built-in flow channel 106 through the fifth valve port 515 and the sixth valve port 516. The cooling After the medium completes heat dissipation in the sixth built-in flow channel 106 through the external radiator, it enters the fourth built-in flow channel 104 through the seventh valve port 517 and the third valve port 513 in the sixth built-in flow channel 106, and then enters the cooling circuit of the battery pack 60 through the battery pack cooling outlet 113 to cool the battery pack 60. After cooling is completed, it enters the first built-in circuit through the battery pack cooling inlet, and then enters the seventh built-in flow channel 107 again through the first valve port 511 and the eighth valve port 518, so as to be driven by the electric water pump 41 again for cooling.

[0073] It should be noted that at this time, the battery water pump 42 will drive the cooling medium to move in the second built-in flow channel 102 toward the second heat exchanger 30, and then enter the third built-in flow channel 103 through the second outlet 32 ​​after completing the heat exchange, and then enter the second built-in flow channel 102 through the fourth valve port 514 and the second valve port 512 to circulate again.

[0074] Therefore, when the thermal management integrated module 100 is in the battery electric drive cooling mode, the electric drive water pump 41 can drive the cooling medium to move in the built-in flow channel to cool the electric drive assembly 70 and the battery pack 60 .

[0075] In some embodiments, Figure 1 and Figure 5 As shown, in the battery heating circuit, the first sub-valve port 521 is connected to the first inlet 21 through the eighth built-in flow channel 108, the first outlet 22 is connected to the inlet of the warm air circuit, the outlet of the warm air circuit is connected to the second sub-valve port 522, the second sub-valve port 522 is connected to the third sub-valve port 523, the third sub-valve port 523 is connected to the battery pack cooling outlet 113 through the ninth built-in flow channel 109, the battery pack cooling inlet 112 is connected to the fourth sub-valve port 524 through the tenth built-in flow channel 110, and the fourth sub-valve port 524 is connected to the first sub-valve port 521.

[0076] Specifically, the thermal management integrated module 100 also includes a heating mode, in which the battery heating circuit can be divided into a heating circuit and an electric drive circuit. In the heating circuit, the cooling medium located in the eighth built-in flow channel 108 moves toward the second heat exchanger 30 driven by the heating water pump 43. The cooling medium enters the first heat exchanger 20 through the first inlet 21 to complete the heat exchange and then enters the warm air circuit from the first outlet 22. The PTC and warm air core in the warm air circuit can provide warm air for the cockpit. The cooling medium then enters the ninth built-in flow channel 109 through the outlet of the warm air circuit, the second sub-valve port 522 and the third sub-valve port 523. In the ninth circuit, the cooling medium can enter the cooling circuit of the battery pack 60 through the battery pack cooling outlet 113. After heating the battery pack 60, the cooling medium enters the tenth built-in flow channel 110 through the battery pack cooling inlet, and then enters the eighth built-in flow channel 108 again through the fourth sub-valve port 524 and the first sub-valve port 521, and is then driven again by the heating water pump 43.

[0077] It should be noted that when the cooling medium is in the second sub-valve port 522, in addition to being connected to the third sub-valve port 523, the second sub-valve port 522 is also connected to the first sub-valve port 521. Part of the cooling medium will directly enter the eighth built-in flow channel 108 through the second sub-valve port 522 and the first sub-valve port 521, which can speed up the circulation of the cooling medium.

[0078] Furthermore, there is an electric drive circuit in the battery heating circuit. In this circuit, the cooling medium in the seventh built-in flow channel 107 moves toward the electric drive component 70 under the drive of the electric drive water pump 41, enters the cooling circuit of the electric drive component 70 through the electric drive cooling outlet 115, and enters the fifth built-in flow channel 105 through the electric drive cooling inlet 114 after completing the cooling of the electric drive component 70. At this time, the fifth valve port 515 is connected to the second valve port 512, and the cooling medium enters the second built-in flow channel 102 through the fifth valve port 515 and the second valve port 512, and moves toward the first built-in flow channel 107 under the drive of the battery water pump 42. The second heat exchanger 30 moves, enters the second heat exchanger 30 through the second inlet 31 to complete the heat exchange, and then enters the third built-in flow channel 103 from the second outlet 32. At this time, the fourth valve port 514 is connected with the sixth valve port 516, and the seventh valve port 517 is connected with the eighth valve port 518. The cooling medium enters the sixth built-in flow channel 106 through the fourth valve port 514 and the sixth valve port 516. After passing through the external heat exchanger in the sixth built-in flow channel 106 for heat exchange again, the cooling medium enters the seventh built-in flow channel 107 again through the seventh valve port 517 and the eighth valve port 518, and is driven to circulate again by the electric water pump 41.

[0079] Therefore, the thermal management integrated module 100 forms a battery heating circuit through the heating circuit and the electric drive circuit, thereby realizing the heating function of the heating mode, thereby realizing the function of providing hot air to the cockpit of the vehicle 1000 and heating the battery pack 60 and the electric drive assembly 70.

[0080] Exemplarily, in this embodiment, the electric water pump 41 and the battery water pump 42 adopt a model with a power of 130W, the heating water pump 43 adopts a model with a power of 60W, and the switching valve assembly 50 includes a five-way valve 52 and a nine-way valve 51, both of which are provided with motors so that the built-in flow channel circulation mode of the manifold 10 can be switched by rotating the valve body angle by the motor.

[0081] Furthermore, when the first heat exchanger 20 is installed on the manifold 10, the flow direction of the cooling medium in the first heat exchanger 20 is perpendicular to the horizontal plane so that the first heat exchanger 20 can better exchange heat for the cooling medium. At the same time, the second heat exchanger 30, the battery cooling electronic expansion valve, the electric drive water pump 41, the battery water pump 42, and the nine-way valve 51 in the above embodiment are all installed on the same side of the manifold 10, and the first heat exchanger 20, the heating water pump 43 and the five-way valve 52 are all installed on the other side of the manifold 10. The axis of the external water pipe on the manifold 10 is parallel to the horizontal plane. At the same time, an electric drive convergence water temperature sensor and a battery circuit water temperature sensor are also installed on the manifold 10, and both are arranged at the electric drive cooling outlet 115 and the battery pack cooling outlet 113.

In this way, the arrangement of external pipelines can be reduced, thereby simplifying the assembly process of the thermal management integrated module 100, and facilitating the reduction of the weight of the thermal management integrated module 100, which is conducive to achieving its lightweight design. At the same time, the switching valve assembly 50 can selectively connect different built-in flow channels to realize multiple working modes of the thermal management system.
