[0045] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0046] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. Additionally, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0047] The following is for reference. Figures 1-10 Description of the thermal management integrated module 100 according to an embodiment of the present invention:

[0048] like Figures 1-9 As shown, the thermal management integrated module 100 according to an 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. 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 an external refrigerant system. The second flow channel is provided with a first inlet 21 and a first outlet 22. The fourth flow channel is provided with a second inlet 31 and a second outlet 32. The manifold 10 is provided with multiple built-in flow channels. The first heat exchanger 20 and the second heat exchanger 30 are both located on the manifold 10. The first inlet 21 and the second inlet 31 are respectively connected to the outlets of different built-in flow channels. 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. 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. This means 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 simplifies the assembly process and improves 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 manifold 10 can be formed by welding 2-3 layers of molded plastic plates containing built-in flow channels using a hot plate. The manifold 10 has several water pipe interfaces, which are connected to the system through pipes. At the same time, the manifold 10 has several brackets, on which vibration damping pads and metal bushings are installed. The manifold 10 is installed on the vehicle 1000 through the brackets. The first heat exchanger 20 and the second heat exchanger 30 can be plate heat exchangers, both of which are installed on the manifold 10. The third flow channel of the second heat exchanger 30 is connected to an external refrigeration system equipped with a battery cooling electronic expansion valve. The built-in flow channel allows 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. This reduces the risk of leakage when the cooling medium flows in the built-in flow channel and also eliminates the need for excessive piping in the vehicle 1000, thus saving internal installation space in the vehicle 1000.

[0052] According to an embodiment of the present invention, the thermal management integrated module 100 has its first heat exchanger 20, second heat exchanger 30, water pump assembly 40, and switching valve assembly 50 all integrated on the manifold 10 and selectively connected through the built-in flow channels of the manifold 10. This reduces the layout of external pipelines, thereby simplifying the assembly process of the thermal management integrated module 100 and making it easier to reduce the weight of the thermal management integrated module 100, which is conducive to 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, such as Figures 1-9 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 are connected through an internal 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 are connected through an internal 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. The cooling outlet and 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 have an open circuit when cooled.

[0055] In some embodiments, such as Figures 1-5 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 has multiple valve ports, including 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 has multiple sub-valve ports, including 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 loop. Alternatively, two built-in flow channels can be connected together through the two sub-valve ports of the five-way valve 52 to form a complete loop. Or, the built-in flow channels can be connected through the valve port of the nine-way valve 51 and the sub-valve ports 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 ports of the five-way valve 52, specifically, two built-in flow channels are connected through two valve ports or two sub-valve ports.

[0057] In some embodiments, such as Figures 1-2 As shown, the water pump assembly 40 includes a battery water pump 42. In the battery pack cooling circuit, the battery pack cooling inlet 112 and the battery pack cooling circuit outlet are connected. 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 located 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. The battery pack cooling outlet 113 is connected to the battery pack cooling circuit inlet.

[0058] Specifically, when the thermal integration module is in cooling mode, there are multiple cooling circuits. In the battery pack cooling circuit, the cooling medium moves from the battery water pump 42 towards the second inlet 31 in the second built-in flow channel 102 under the action of the battery water pump 42. After releasing heat in the second heat exchanger 30, it enters the third built-in flow channel 103 through the second outlet 32. At this time, the fourth valve port 514 will be connected to the third valve port 513. 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 to the second valve port 512. 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 for heat exchange again.

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

[0060] Therefore, the battery water pump 42 is installed in the battery pack cooling circuit. When the battery pack 60 is being cooled, the battery water pump 42 can provide power to the cooling medium in the cooling circuit, so that the cooling medium has enough power to move in the battery pack cooling circuit, thereby better cooling the battery pack 60.

[0061] In some embodiments, such as Figures 1-2 As shown, the water pump assembly 40 also includes an electric water pump 41. In the cooling circuit of the electric drive assembly, the electric drive cooling inlet 114 is connected to the outlet of the cooling circuit of the electric drive assembly. The fifth internal flow channel 105 is connected between the electric drive cooling inlet 114 and the fifth valve port 515. The fifth valve port 515 is connected to the sixth valve port 516. The sixth internal flow channel 106 is connected between the sixth valve port 516 and the seventh valve port 517. An external heat dissipation pipe 80 is connected to the sixth internal flow channel 106. A radiator is provided on the external heat dissipation pipe 80. The seventh valve port 517 is connected to the eighth valve port 518. The seventh internal flow channel 107 is connected between the eighth valve port 518 and the electric drive cooling outlet 115. The electric water pump 41 is located in the seventh internal flow channel 107. The electric drive cooling outlet 115 is connected to the inlet of the cooling circuit of the electric drive assembly.

[0062] Specifically, when the thermal management integrated module 100 is in cooling mode, there is also a cooling circuit for the electric drive component. An electric water pump 41 is installed in this cooling circuit. The electric water pump 41 drives the cooling medium to move towards the electric drive component 70 in the seventh built-in flow channel 107. After passing through the electric drive cooling outlet 115, it enters the cooling circuit of the electric drive component 70. After cooling the electric drive component 70, the cooling medium enters the fifth built-in flow channel 105 from the electric drive cooling inlet 114. At this time, the fifth valve port 515 and the sixth... When valve port 516 is connected, the cooling medium enters the sixth internal flow channel 106 after passing through the fifth valve port 515 and the sixth valve port 516. The sixth internal flow channel 106 is connected to an external heat dissipation pipe 80. The cooling medium can dissipate heat in the external radiator before entering the sixth internal flow channel 106. At this time, the seventh valve port 517 and the eighth valve port 518 are connected. The cooling medium enters the seventh internal 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 leading to the five-way valve 52. In this flow path, the cooling medium moves towards the fifth sub-valve port 525 in the seventh built-in flow channel 107 under the action of the electric 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 enters the eighth built-in flow channel 108. The eighth built-in flow channel 108 is also equipped with a heating water pump 43 for cooling. The medium in the eighth built-in flow channel 108 will move toward the first inlet 21 under the drive of the heating water pump 43 and enter the first heat exchanger 20 for heat exchange. After the heat exchange is completed, it enters 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 the same as the path through the nine-way valve 51 in the above embodiment, which will not be described again here.

[0064] Therefore, the electric water pump 41 is installed 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 to the cooling medium in the refrigeration circuit of the electric drive component, so that the cooling medium has enough 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, so that the cooling medium can get a good heat exchange effect, thereby improving the cooling effect of the electric drive component 70.

[0065] In some embodiments, such as 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 located in the eighth built-in flow channel 108. The first outlet 22 is connected to the inlet of the heating circuit of the vehicle 1000. The outlet of the heating circuit is connected to the second sub-valve port 522. 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 and utilization 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 the cooling medium exchanges heat through the first heat exchanger 20, it enters the heating circuit of the vehicle 1000 from the first outlet 22. The heating circuit of the vehicle 1000 contains a PTC and a heating core. When the cooling medium flows through the PTC and the heating core, it can provide warm air to the driver's cabin of the vehicle 1000. The outlet of the heating 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 the cooling medium flows out of the heating circuit, it enters the eighth built-in flow channel 108 through the second sub-valve port 522 and the first sub-valve port 521, so that it can be driven by the heating water pump 43 again.

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

[0068] In some embodiments, such as Figure 1 and Figure 3 As shown, in the battery waste heat recovery circuit, the second valve port 512 is connected to the second built-in flow channel 102 and the second inlet 31, 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 circuit of the battery waste heat recovery circuit, the battery water pump 42 drives the cooling medium to move towards 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 circuit. After absorbing heat, it enters the seventh built-in flow channel 107 through the first valve port 511 and the eighth valve port 518. Then, driven by the electric water pump 41 in the seventh built-in flow channel 107, it moves towards the electric drive assembly 70, and then enters the cooling circuit of the electric drive assembly. After absorbing heat from the electric drive assembly 70, it enters the fifth built-in flow channel 105 through the electric drive cooling inlet 114, and then enters the second built-in flow channel 102 through the fifth valve port 515 and the third valve port 513, 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 absorbing heat, it can enter the seventh built-in flow channel 107 and be driven by the electric water pump 41 to absorb heat from the electric drive component 70. Finally, it enters the side of the battery water pump 42. In this way, waste heat can be utilized from both the battery pack 60 and the electric drive component 70, thereby making the heat absorption efficiency higher.

[0071] In some embodiments, such as Figure 1 and Figure 4 As shown, in the battery drive cooling circuit, the eighth valve port 518 is connected to the drive cooling outlet 115 through the seventh built-in flow channel 107, the 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 pipe 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 located in the seventh built-in flow channel 107 moves towards the electric drive component 70 via the electric drive water pump 41. After passing through the electric drive cooling outlet 115, it enters the cooling circuit of the electric drive component 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 for further cooling. After the medium is cooled by the external heat sink in the sixth built-in flow channel 106, 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. Then, it enters the cooling circuit of the battery pack 60 through the battery pack cooling outlet 113 to cool the battery pack 60. After cooling, 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 that it is driven by the electric water pump 41 to cool again.

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

[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 component 70 and the battery pack 60.

[0075] In some embodiments, such as 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 this mode, 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 towards the second heat exchanger 30 under the drive of the heating water pump 43. The cooling medium enters the first heat exchanger 20 through the first inlet 21 to complete 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 to the cockpit. The cooling medium then enters the ninth internal flow channel 109 through the outlet of the heating 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 the battery pack 60 is heated, it enters the tenth internal flow channel 110 through the battery pack cooling inlet, and then enters the eighth internal 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. Some 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 accelerate the circulation of the cooling medium.

[0078] Furthermore, the battery heating circuit also includes an electric drive circuit. In this circuit, the cooling medium located in the seventh internal flow channel 107 moves towards the electric drive assembly 70 under the drive of the electric drive water pump 41, and enters the cooling circuit of the electric drive assembly 70 through the electric drive cooling outlet 115. After completing the cooling of the electric drive assembly 70, it enters the fifth internal flow channel 105 through the electric drive cooling inlet 114. At this time, the fifth valve port 515 is connected to the second valve port 512. The cooling medium then enters the second internal flow channel 102 through the fifth valve port 515 and the second valve port 512, and moves towards the fifth internal flow channel 105 under the drive of the battery water pump 42. The second heat exchanger 30 moves, and the medium enters the second heat exchanger 30 through the second inlet 31 to complete the heat exchange, and then enters the third internal flow channel 103 through the second outlet 32. At this time, the fourth valve port 514 is connected to the sixth valve port 516, and the seventh valve port 517 is connected to the eighth valve port 518. The cooling medium enters the sixth internal flow channel 106 through the fourth valve port 514 and the sixth valve port 516. After being heat-exchanged again by the external heat exchanger in the sixth internal flow channel 106, the cooling medium enters the seventh internal flow channel 107 again through the seventh valve port 517 and the eighth valve port 518, and is then 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, and thus realizing the functions of providing hot air to the cockpit of the vehicle 1000 and heating the battery pack 60 and the electric drive component 70.

[0080] For example, in this embodiment, the electric water pump 41 and the battery water pump 42 are models with a power of 130W, the heating water pump 43 is 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 equipped with motors so that the built-in flow channel circulation mode of the manifold 10 can be switched by rotating the valve body angle through 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 with the cooling medium. At the same time, the second heat exchanger 30, the battery cooling electronic expansion valve, the electric 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, while 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, the electric drive manifold water temperature sensor and the battery circuit water temperature sensor are also installed on the manifold 10, which are located at the electric drive cooling outlet 115 and the battery pack cooling outlet 113.

[0082] The present invention also proposes a vehicle 1000.

This reduces the layout of external pipelines, thereby simplifying the assembly process of the thermal management integrated module 100 and making it easier to reduce 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.
