Technical Field

[0001] This application relates to the field of thermal management technology, and more particularly to a thermal management component. Background Technology

[0002] The thermal management assembly comprises several functional components, which are connected and communicated with each other via piping. To reduce piping, at least some of the functional components are integrated together using connectors with internal channels to form the thermal management assembly. In related technologies, the first heat exchanger and the second heat exchanger are fixedly connected to opposite sides of a connecting bridge, and the inner cavities of the first heat exchanger and the second heat exchanger are connected via piping. This requires using relatively long piping to bypass the connecting bridge, resulting in a longer path for connecting the first and second heat exchangers and greater flow resistance. Summary of the Invention

[0003] The purpose of this application is to provide a thermal management component that helps to shorten the connection path between the first heat exchanger and the second heat exchanger and reduce flow resistance.

[0004] To achieve the above objectives, this application adopts the following technical solution:

[0005] A thermal management assembly includes a first heat exchanger, a second heat exchanger, and a connecting bridge, the connecting bridge being at least partially located between the first heat exchanger and the second heat exchanger, the first heat exchanger and the second heat exchanger being fixedly connected to opposite sides of the connecting bridge;

[0006] The connecting bridge has a first channel and a second channel, which are interconnected in the connecting bridge. The first channel connects the inner cavity of the first heat exchanger and the inner cavity of the second heat exchanger, and the second channel is connected to the external space of the thermal management component. The first channel extends along the thickness direction of the connecting bridge and passes through both sides of the connecting bridge.

[0007] In this application, the first channel connects the inner cavity of the first heat exchanger and the inner cavity of the second heat exchanger. The first channel extends along the thickness direction of the connecting bridge and penetrates both sides of the connecting bridge, which helps to shorten the connection path between the first heat exchanger and the second heat exchanger and reduce flow resistance.

[0030] The thermal management component of an exemplary embodiment of this application will now be described in detail with reference to the accompanying drawings. Unless otherwise specified, the features of the following embodiments and implementations can complement or combine with each other.

[0031] According to one possible embodiment of the thermal management component of this application, refer to Figure 4 and Figures 13 to 16A thermal management assembly includes a first heat exchanger 2, a second heat exchanger 3, and a connecting bridge 6. The connecting bridge 6 is at least partially located between the first heat exchanger 2 and the second heat exchanger 3, and the first heat exchanger 2 and the second heat exchanger 3 are fixedly connected to opposite sides of the connecting bridge 6. The connecting bridge 6 has a first channel 614 and a second channel 615, which are interconnected within the connecting bridge 6. The first channel 614 connects the inner cavity of the first heat exchanger 2 and the inner cavity of the second heat exchanger 3, and the second channel 615 communicates with the external space of the thermal management assembly. The first channel 614 extends along the thickness direction of the connecting bridge 6 and penetrates both sides of the connecting bridge 6. Compared with the prior art, this design shortens the connection path between the first heat exchanger 2 and the second heat exchanger 3, reducing flow resistance.

[0032] In some possible embodiments, reference Figure 18 The first channel 614 extends along the thickness direction of the connecting bridge 6 and penetrates both sides of the connecting bridge 6, while the second channel 615 extends along the width direction of the connecting bridge 6 and penetrates one side of the connecting bridge 6. The central axis of the first channel 614 is perpendicular to the central axis of the second channel 615, and the first channel 614 and the second channel 615 form a T-shaped channel. Compared with the prior art, this method is advantageous in shortening the connection path between the first heat exchanger 2 and the second heat exchanger 3, reducing flow resistance, and simplifying the process.

[0033] Reference Figures 13 to 16 The connecting bridge 6 also has a third channel 616, a fourth channel 617, and a fifth channel 618. The third channel 616 communicates with the inner cavity of the first heat exchanger 2, the fourth channel 617 communicates with the inner cavity of the first heat exchanger 2, and the fifth channel 618 communicates with the inner cavity of the second heat exchanger 3. The second channel 615, the third channel 616, the fourth channel 617, and the fifth channel 618 are isolated from each other in the connecting bridge 6. The surface of the connecting bridge 6 has a first connecting port 61, a second connecting port 62, and a third connecting port 63, which are located on different sides of the connecting bridge 6. The second connecting port 62 and the third connecting port 63 are connected through a first channel 614. The second connecting port 62 communicates with the inner cavity of the first heat exchanger 2, and the third connecting port 63 communicates with the inner cavity of the second heat exchanger 3. The first connecting port 61 communicates with the external space of the thermal management assembly.

[0034] The first channel 614 and the second channel 615 are interconnected in the connecting bridge 6. The second channel 615, the third channel 616, the fourth channel 617, and the fifth channel 618 are isolated from each other in the connecting bridge 6. Some channels of the second channel 615, the third channel 616, the fourth channel 617, and the fifth channel 618 can be connected to the external space of the thermal management component. This allows the first heat exchanger 2 and the second heat exchanger 3, located on opposite sides of the connecting bridge 6, to be connected through the internal channels of the connecting bridge 6. This helps to reduce the piping connections between the first heat exchanger 2 and the second heat exchanger 3. Furthermore, the connecting bridge 6, the first heat exchanger 2, and the second heat exchanger 3 constitute multiple pathways for the flow of heat exchange medium. Setting multiple channels to be connected to the external space of the thermal management component can improve the practicality of the thermal management component and enrich its application scenarios.

[0035] Reference Figures 13 to 16 The surface of the connecting bridge 6 has a fourth connecting port 64, a fifth connecting port 65, and a sixth connecting port 66, all located on the same side of the connecting bridge 6. The first connecting port 61, the second connecting port 62, the third connecting port 63, and the fourth connecting port 64 are located on different sides of the connecting bridge 6. The surface of the connecting bridge 6 also has a seventh connecting port 67, an eighth connecting port 68, and a ninth connecting port 69, all located on the same side of the connecting bridge 6. The second connecting port 62, the seventh connecting port 67, and the eighth connecting port 68 are located on the same side of the connecting bridge 6. The third connecting port 63 and the ninth connecting port 69 are located on the same side of the connecting bridge 6. The fourth connecting port 64 and the seventh connecting port 67 are connected through a third channel 616, the fifth connecting port 65 and the eighth connecting port 68 are connected through a fourth channel 617, and the sixth connecting port 66 and the ninth connecting port 69 are connected through a fifth channel 618. The ninth connecting port 69 communicates with the inner cavity of the second heat exchanger 3, the seventh connecting port 67 communicates with the inner cavity of the first heat exchanger 2, and the eighth connecting port 68 communicates with the inner cavity of the first heat exchanger 2. By strategically positioning some of the connecting bridge 6's ports on different sides, it can be used to connect different structural components. Similarly, by strategically positioning some of the connecting bridge 6's ports on the same side, it can be used to connect different interfaces of the same structural component. Furthermore, strategically positioning the connecting bridge 6's ports helps reduce the piping connections of the thermal management components, thereby reducing the space occupied by the thermal management components.

[0036] refer to Figure 13The connecting bridge 6 includes a top surface, bottom surface, left side surface, right side surface, front side surface, and rear side surface. The top and bottom surfaces of the connecting bridge 6 are located on opposite sides along the third direction Z, the left and right sides are located on opposite sides along the second direction X, and the front and rear sides are located on opposite sides along the first direction Y. The length direction of the connecting bridge 6 is parallel to or coincides with the third direction Z, the width direction is parallel to or coincides with the first direction Y, and the thickness direction is parallel to or coincides with the second direction X. The second connecting port 62, the seventh connecting port 67, and the eighth connecting port 68 are located on the right side surface of the connecting bridge 6 and communicate with the inner cavity of the first heat exchanger 2. The first connecting port 61 is located on the front side surface of the connecting bridge 6 and communicates with the external space of the thermal management component. The fourth connecting port 64, the fifth connecting port 65, and the sixth connecting port 66 are located on the top surface of the connecting bridge 6 and communicate with the inner cavity of the valve island 7. The third connecting port 63 and the ninth connecting port 69 are located on the left side of the connecting bridge 6 and are connected to the inner cavity of the second heat exchanger 3.

[0037] Reference Figure 13 and Figure 15The connecting bridge 6 has a first groove 610 and a second groove 611. The openings of the first groove 610 and the second groove 611 are generally elongated and distributed approximately along the length of the connecting bridge 6. The first groove 610 is formed by a portion of the connecting bridge 6 facing the first heat exchanger 2 that is recessed inward. The second groove 611 is formed by a portion of the connecting bridge 6 facing the second heat exchanger 3 that is recessed inward. The cavities of the first groove 610 and the second groove 611 are isolated from each other in the connecting bridge 6. The opening of the first groove 610 faces the first heat exchanger 2, and the opening of the second groove 611 faces the second heat exchanger 3. The cavity of the first groove 610 is located between the side of the first heat exchanger 2 facing the connecting bridge 6 and the connecting bridge 6, and the cavity of the second groove 611 is located between the side of the second heat exchanger 3 facing the connecting bridge 6 and the connecting bridge 6. During assembly, the first heat exchanger 2 and the second heat exchanger 3 are fixedly connected to the connecting bridge 6, respectively. The edge of the opening of the first groove 610 is sealed to the side of the first heat exchanger 2 facing the connecting bridge 6, and the edge of the opening of the second groove 611 is sealed to the side of the second heat exchanger 3 facing the connecting bridge 6. The fourth channel 617 includes the cavity of the first groove 610, and the fifth channel 618 includes the cavity of the second groove 611. The first groove 610 and the second groove 611 can be of any shape and size. The first groove 610 allows the fifth connecting port 65 and the eighth connecting port 68, located on different sides of the connecting bridge 6, to connect, thereby achieving communication between the inner cavity of the first heat exchanger 2 and the inner cavity of the valve island 7, located on different sides of the connecting bridge 6. The second groove 611 allows the sixth connecting port 66 and the ninth connecting port 69, located on different sides of the connecting bridge 6, to connect. By providing the first groove 610 and the second groove 611, the number of holes drilled inside the connecting bridge 6 can be reduced, thereby reducing the manufacturing difficulty of the connecting bridge 6.

[0038] Reference Figure 13 The connecting bridge 6 includes a first notch 612 and a second notch 613, both of which are isolated from the internal channels of the connecting bridge 6. The first notch 612 and the second notch 613 are located on opposite sides of the width direction of the connecting bridge 6. The first notch 612 and the second notch 613 can be of any shape; optionally, they are approximately U-shaped. Alternatively, the first notch 612 and the second notch 613 are symmetrically arranged on the connecting bridge, giving the connecting bridge 6 an approximately "I" shape.

[0039] In optional embodiments, the connecting bridge 6 includes only the first notch 612, or only the second notch 613. By providing the first notch 612 and / or the second notch 613 while ensuring the wall thickness of the internal channels of the connecting bridge 6, i.e., ensuring the pressure resistance of the connecting bridge 6, the weight of the thermal management component can be reduced, thus reducing material costs. In optional embodiments, the connecting bridge 6 may also have holes to reduce the weight of the thermal management component and reduce material costs. It is understood that the shape, number, location, and size of the notches or holes on the connecting bridge 6 are not specifically limited here, as long as the pressure resistance of the connecting bridge 6 is ensured, and can be selected according to actual conditions.

[0040] Reference Figure 4 The connecting bridge 6 has a dimension larger in its length direction than in its width direction, and a dimension larger in its width direction than in its thickness direction. The first heat exchanger 2 and the second heat exchanger 3 are located on opposite sides of the connecting bridge 6 in its thickness direction, and are arranged sequentially along the second direction X. By rationally arranging the first heat exchanger 2, the second heat exchanger 3, and the connecting bridge 6 according to their dimensional characteristics, with the first heat exchanger 2 and the second heat exchanger 3 located on the smaller sides of the connecting bridge 6, space can be effectively utilized, thereby reducing the space occupied by the thermal management components.

[0041] In some possible embodiments, refer to Figures 1 to 3The thermal management assembly includes a first heat exchanger 1 and a base 20. The first heat exchanger 1, a first heat exchanger 2, and a second heat exchanger 3 are fixedly connected to the base 20. The base 20 has several flow paths. The inner cavities of the first heat exchanger 2 and the second heat exchanger 3 are connected through one of the flow paths of the base 20, and the inner cavity of the first heat exchanger 1 is connected to another flow path of the base 20. The projection of the first heat exchanger 1 onto a plane perpendicular to the first direction Y at least partially coincides with the projection of the second heat exchanger 3 onto a plane perpendicular to the first direction Y. The projections of the first heat exchanger 2 onto a plane perpendicular to the second direction X at least partially coincide with the projections of the second heat exchanger 3 onto a plane perpendicular to the second direction X. The first heat exchanger 1 and the second heat exchanger 3 are arranged side by side along the first direction Y and side by side along the second direction X. The dimension of the second heat exchanger 3 in the third direction Z is greater than its dimensions in the second direction X and the first direction Y. The first direction Y, the second direction X, and the third direction Z are perpendicular to each other. The first heat exchanger 1, the first heat exchanger 2, and the second heat exchanger 3 are fixedly connected to different sides of the base 20, respectively. The first heat exchanger 1, the first heat exchanger 2, and the second heat exchanger 3 are arranged in a ring-like pattern, roughly in an L-shape or T-shape. The first heat exchanger 1 and the first heat exchanger 2 are located on the smaller sides of the second heat exchanger 3, making efficient use of the peripheral space of the first heat exchanger 1, the first heat exchanger 2, and the second heat exchanger 3. Communication between the inner cavities of the first heat exchanger 1, the first heat exchanger 2, and the second heat exchanger 3 is achieved through the base 20. The close proximity of the first heat exchanger 1, the first heat exchanger 2, and the second heat exchanger 3, omitting or shortening connecting pipes, reduces flow resistance and helps to minimize the space occupied by the thermal management components.

[0042] In some possible embodiments, refer to Figures 1 to 3 In one embodiment, the first heat exchanger 1 has a larger dimension in the third direction Z than in the second direction X and Y. Similarly, the first heat exchanger 2 has a larger dimension in the third direction Z than in the second direction X and Y. In an optional embodiment, the first heat exchanger 1 has a larger dimension in the first direction Y than in the second direction X, the first heat exchanger 2 has a larger dimension in the first direction Y than in the second direction X, and the second heat exchanger 3 has a larger dimension in the first direction Y than in the second direction X. Furthermore, the second heat exchanger 3 is located on the side with the smaller dimension of the first heat exchanger 1, and the second heat exchanger 2 is located on the side with the smaller dimension of the first heat exchanger 2. This distribution makes the structural arrangement of the first heat exchanger 1, first heat exchanger 2, and second heat exchanger 3 more compact and reasonable, further reducing the space occupied by the thermal management components.

[0043] In some possible embodiments, refer to Figures 1 to 3The thermal management assembly includes a reservoir 4, a first heat exchanger 1, a first heat exchanger 2, a second heat exchanger 3, and a reservoir 4, all of which are fixedly connected to a base 20. The inner cavity of the reservoir 4 communicates with the inner cavity of the base 20. The projection of the reservoir 4 onto a plane perpendicular to the first direction Y at least partially overlaps with the projection of the first heat exchanger 2 onto the same plane. The projection of the reservoir 4 onto a plane perpendicular to the second direction X at least partially overlaps with the projection of the first heat exchanger 1 onto the same plane. The reservoir 4 and the first heat exchanger 2 are arranged side-by-side along the first direction Y, and the reservoir 4 and the first heat exchanger 1 are arranged side-by-side along the second direction X. The reservoir 4 is located within the angle formed by the first heat exchanger 1, the first heat exchanger 2, and the second heat exchanger 3. The first heat exchanger 1, the first heat exchanger 2, the second heat exchanger 3, and the liquid reservoir 4 are fixedly connected to different sides of the base 20. They are arranged in a circular pattern, roughly square or rectangular. By making efficient use of the surrounding space of the first heat exchanger 1, the first heat exchanger 2, the second heat exchanger 3, and the liquid reservoir 4, communication is achieved between the inner cavities of the first heat exchanger 1, the first heat exchanger 2, the second heat exchanger 3, and the liquid reservoir 4 through the base 20. The close proximity of the first heat exchanger 1, the first heat exchanger 2, the second heat exchanger 3, and the liquid reservoir 4 reduces flow resistance and minimizes the space occupied by the thermal management components.

[0044] In an optional embodiment, the dimension of the liquid reservoir 4 in the third direction Z is larger than its dimension in the second direction X, and the dimension of the liquid reservoir 4 in the third direction Z is larger than its dimension in the first direction Y. The first heat exchanger 1 and the first heat exchanger 2 are located on the two sides with smaller dimensions of the liquid reservoir 4, the liquid reservoir 4 is located on the side with smaller dimensions of the first heat exchanger 2, and the liquid reservoir 4 is located on the side with smaller dimensions of the first heat exchanger 1. This distribution makes the structural arrangement of the first heat exchanger 1, the first heat exchanger 2, the second heat exchanger 3, and the liquid reservoir 4 more compact and reasonable, which further helps to reduce the space occupied by the thermal management components.

[0045] Reference Figure 8 and Figure 9The thermal management component includes a base 20, which includes a valve island 7 and a connecting bridge 6. The connecting bridge 6 and the valve island 7 are interconnected, with the valve island 7 located on one side of the connecting bridge 6 along its length. The dimension of the valve island 7 in the third direction Z is smaller than its dimensions in the first direction Y and the second direction X. The dimension of the connecting bridge 6 in the third direction Z is larger than its dimensions in the first direction Y and the second direction X. The connecting bridge 6 is located on the side of the valve island 7 with the smaller dimension, and the valve island 7 is located on the side of the connecting bridge 6 with the larger dimension. The connecting bridge 6 and the valve island 7 are approximately T-shaped, making the structure of the components distributed around the base 20 more compact and reducing the space occupied by the thermal management component. In an optional embodiment, the base 20 may only include the valve island 7. In an optional embodiment, the base 20 may also only include the connecting bridge 6. In an optional embodiment, the base 20 may include both the connecting bridge 6 and the valve island 7. No specific limitation is made here; the choice is made according to the usage requirements of the thermal management component.

[0046] In some possible embodiments, refer to Figure 3 Each structural component of the thermal management assembly includes a top surface, a bottom surface, a left side surface, a right side surface, a front side surface, and a rear side surface. The top and bottom surfaces of each structural component are located on opposite sides of the component along the third direction Z, the left and right sides of each structural component are located on opposite sides of the component along the second direction X, and the front and rear sides of each structural component are located on opposite sides of the component along the first direction Y.

[0047] The dimensions of the first heat exchanger 2, the second heat exchanger 3, and the connecting bridge 6 in the third direction Z are approximately the same. The dimensions of the first heat exchanger 2, the second heat exchanger 3, and the connecting bridge 6 in the first direction Y are also approximately the same. The right side of the connecting bridge 6 is fixedly connected to the left side of the first heat exchanger 2, and the left side of the connecting bridge 6 is fixedly connected to the right side of the second heat exchanger 3. This distribution ensures that the top surfaces of the first heat exchanger 2, the second heat exchanger 3, and the connecting bridge 6 are approximately on the same plane, and the bottom surfaces of the first heat exchanger 2, the second heat exchanger 3, and the connecting bridge 6 are also approximately on the same plane, simplifying the process.

[0048] The dimension of the first heat exchanger 1 in the third direction Z is larger than that of the first heat exchanger 2 and the second heat exchanger 3 in the third direction Z. The bottom surface of the valve island 7 is fixedly connected to the top surface of the connecting bridge 6, and the front side of the first heat exchanger 1 is fixedly connected to the rear side of the valve island 7. The dimension of the liquid receiver 4 in the third direction Z is smaller than that of the first heat exchanger 2 and the second heat exchanger 3 in the third direction Z, and the top surface of the liquid receiver 4 is fixedly connected to the bottom surface of the valve island 7. The liquid receiver 4 is located in the triangular space formed by the first heat exchanger 1, the first heat exchanger 2, and the second heat exchanger 3. Arranging the first heat exchanger 1, the first heat exchanger 2, the second heat exchanger 3, the liquid receiver 4, the connecting bridge 6, and the valve island 7 in an orderly manner according to their own dimensional characteristics is beneficial to the assembly and fixing of the various structural components of the thermal management assembly. It can also effectively utilize space, making the structural layout more compact and reasonable, thereby reducing the space occupied by the thermal management assembly.

[0049] Reference Figures 6 to 7 The first heat exchanger 1 has a first interface 11, a second interface 12, a third interface 13, and a fourth interface 14. The first interface 11, third interface 13, and fourth interface 14 are located on the same side, while the second interface 12 is located on opposite sides of the first interface 11.

Optionally, when applied to a thermal management system, the heat exchange medium flowing in the first flow channel is a refrigerant, and the heat exchange medium flowing in the second flow channel is a coolant. The refrigerant flowing in the first flow channel and the coolant flowing in the second flow channel exchange heat in the first heat exchanger 1.

The first port 21 and the second port 22 are connected through the third flow channel, and the third port 23 and the fourth port 24 are connected through the fourth flow channel. Optionally, when applied to a thermal management system, the heat exchange medium flowing in the third and fourth flow channels is refrigerant. The refrigerant flowing in the third and fourth flow channels is from different sections of the same loop. The two refrigerants exchange heat in the first heat exchanger 2, which can improve the heat exchange efficiency of the thermal management system.

[0051] Reference Figures 6 to 7 The second heat exchanger 3 has a first connection port 31, a second connection port 32, a third connection port 33, and a fourth connection port 34.

The first and second connection ports 31 and 32 are connected through the fifth flow channel, and the third and fourth connection ports 33 and 34 are connected through the sixth flow channel. Optionally, when applied to a thermal management system, the heat exchange medium flowing in the sixth flow channel is a refrigerant, and the heat exchange medium flowing in the fifth flow channel is a coolant. The refrigerant flowing in the sixth flow channel and the coolant flowing in the fifth flow channel exchange heat in the second heat exchanger 3. The structure and working principle of the dual-channel heat exchanger are well known to those skilled in the art, and will not be described in detail here.

In the valve island 7, the second passage 721 is isolated from the first passage 720, the third passage 722, the fourth passage 723, the fifth passage 724, and the sixth passage 725. Some passages in the first passage 720, the second passage 721, the third passage 722, the fourth passage 723, the fifth passage 724, and the sixth passage 725 can communicate with the external space of the thermal management component. The first heat exchanger 1 and the liquid receiver 4 are fixedly connected to the valve island 7. The inner cavity of the first heat exchanger 1 communicates with the internal passages of the valve island 7, and the inner cavity of the liquid receiver 4 also communicates with the internal passages of the valve island 7, which helps reduce the piping connections between the first heat exchanger 1 and the liquid receiver 4. The valve island 7, the first heat exchanger 1, and the liquid receiver 4 constitute multiple passages for the flow of heat exchange media. Having multiple passages communicating with the external space of the thermal management component improves the practicality of the thermal management component and enriches its application scenarios.

A first passage 720 communicates with first channel port 71, a second passage 721 communicates with second channel port 72 and sixth channel port 76, a third passage 722 communicates with third channel port 73, a fifth passage 724 communicates with fifth channel port 75, and a sixth passage 725 communicates with seventh channel port 77. By strategically positioning some of the channel openings of valve island 7 on different sides of valve island 7, they can be used to connect different structural components. By strategically positioning some of the channel openings of valve island 7 on the same side of valve island 7, they can be used to connect different interfaces of the same structural component. Strategically positioning the distribution of the channel openings of valve island 7 helps to reduce the piping connections of the thermal management components, thereby reducing the space occupied by the thermal management components.

[0056] In some embodiments, refer to Figure 3 and Figure 12 The thermal management component includes a valve core assembly 5, which is mounted and sealed together with the valve island 7.

The valve island 7 has at least one of the first mounting cavity 78, the second mounting cavity 79, the third mounting cavity 79, and the fourth mounting cavity 79. Correspondingly, the arrangement of the internal passages and channels of the valve island 7 can be adapted.

[0057] Reference Figure 10 The valve island 7 has a first groove 712 and a second groove 713, which are isolated from each other within the valve island 7. The openings of the first groove 712 and the second groove 713 are located on the same side of the valve island 7. The openings of the first groove 712 and the second groove 713 are approximately L-shaped. The second groove 713 is located on opposite sides of the valve island 7 to the valve core assembly 5. The third passage 722 includes the cavity of the first groove 712, and the second passage 721 includes the cavity of the second groove 713.

[0058] In some embodiments, refer to Figure 8 and Figure 10 The thermal management assembly includes a base plate 715, which has a first hole 716, a second hole 717, a third hole 718, and a fourth hole 719 spaced apart. These holes extend along the thickness direction of the base plate 715 and penetrate both sides of the base plate 715 along its thickness. A first groove 712 and a second groove 713 are formed by inwardly recessing a portion of the side of the valve island 7 facing the base plate 715. During assembly, the base plate 715 is fixedly connected to the valve island 7. The edge of the opening of the first groove 712 is sealed to one side of the base plate 715, and the edge of the opening of the second groove 713 is sealed to the same side of the base plate 715.

The opening 714 can be of any shape; optionally, it is approximately U-shaped. By providing the opening 714 while ensuring the wall thickness of the internal passage of the valve island 7, i.e., ensuring the pressure resistance of the valve island 7, the weight of the thermal management component can be reduced, thus reducing material costs. In an optional embodiment, the valve island 7 can also be provided with holes to reduce the weight of the thermal management component and reduce material costs. It is understood that the shape, number, position, and size of the opening 714 or holes on the valve island 7 are not specifically limited here, as long as the pressure resistance of the valve island 7 is ensured, and the selection is based on actual conditions.

[0060] A thermal management system is primarily used to manage cooling and heating loads to meet specific needs, such as cooling / heating requirements for cabin space, motor cooling, and battery heating / cooling. A portion of the cooling / heating load is supplied through methods such as operating a refrigerant circulation loop, starting heaters, or utilizing the cooling capacity of the coolant itself, while some heat is obtained by recovering cooling / heat from other sources. Integrating certain components of the thermal management system creates a thermal management assembly. It is understood that the components and their positions within this assembly can be adjusted according to actual needs without affecting its functionality.

[0061] The thermal management component of the technical solution of this application can have multiple implementations, at least one of which can be applied to a vehicle thermal management system, at least one of which can be applied to other thermal management systems such as a household thermal management system or a commercial thermal management system. The following description takes the thermal management component applied to a vehicle thermal management system as an example and is illustrated with reference to the accompanying drawings. The fluids are refrigerant and coolant. The refrigerant can be R134a or CO2 or other forms of refrigerant, and the coolant can be a mixture of ethanol and water or other cooling media.

[0062] In one possible embodiment, reference is made to... Figures 17 to 19 , combined Figures 1 to 16 The thermal management system includes the thermal management components of any of the above embodiments, and further includes a compressor 8, a first indoor heat exchanger 9, and a second indoor heat exchanger 10. This embodiment uses the thermal management components as an example. Figures 1 to 3 The following description uses all components as examples. The first heat exchanger 1 serves as a water-cooled condenser, used for heat exchange between the refrigerant and the coolant in the cooling circuit during refrigeration mode. The coolant in the cooling circuit can exchange heat with the atmospheric environment. The first heat exchanger 2 serves as an intermediate heat exchanger, used for heat exchange between high-temperature and low-temperature refrigerant, improving system heat exchange efficiency. The second heat exchanger 3 serves as a battery cooler or waste heat recovery unit, used for heat exchange between the refrigerant and the coolant in the battery coolant circuit. The coolant in the battery coolant circuit exchanges heat with the battery, thereby managing battery thermally. The first indoor heat exchanger 9 serves as a condenser, used to heat the air around it. The second indoor heat exchanger 10 serves as an evaporator, used to cool the air around it. In the diagram, solid lines indicate a connected state, arrows indicate the direction of refrigerant / coolant flow, and dashed lines indicate a closed state. In this application, the cooling circuit and the battery coolant circuit can be connected or isolated from each other, depending on the design of the thermal management system.

[0063] A damper is provided beside the first indoor heat exchanger 9 to control whether air flows through it and the amount of airflow, thereby controlling whether heat exchange occurs at the first indoor heat exchanger 9 and its heat exchange effect. Similarly, a damper can also be provided beside the second indoor heat exchanger 10 to control whether heat exchange occurs at it and its heat exchange effect. In some embodiments, a damper can also be provided between the first and second indoor heat exchangers 9, with the first indoor heat exchanger 9 located downstream of the second indoor heat exchanger 10. The damper controls whether air flows through the first indoor heat exchanger 9 and the amount of airflow. Air can flow through the second indoor heat exchanger 10 regardless of whether the damper is open or closed.

[0064] Reference Figures 1 to 17 The compressor 8, the first indoor heat exchanger 9, and the second indoor heat exchanger 10 are respectively connected to the thermal management assembly, either directly or through pipelines. The outlet of the compressor 8 is connected to the third channel port 73, the inlet of the compressor 8 is connected to the first port 21 of the first heat exchanger 2, the inlet of the first indoor heat exchanger 9 is connected to the first interface 11 of the first heat exchanger 1, the outlet of the first indoor heat exchanger 9 is connected to the first interface 41 of the liquid receiver 4, the inlet of the second indoor heat exchanger 10 is connected to the seventh channel port 77 of the valve island 7, and the outlet of the second indoor heat exchanger 10 is connected to the first connecting port 61 of the connecting bridge 6. The third interface 13 and the fourth interface 14 of the first heat exchanger 1 are connected to the heat dissipation coolant circuit, and the first connection port 31 and the second connection port 32 of the second heat exchanger 3 are connected to the battery coolant circuit.

[0065] In this application, it should be understood that the thermal management system includes a first valve 511, a second valve 521, a third valve 531, and a fourth valve 541. Specifically, the first valve core 51 and the valve island 7 constitute the first valve 511, which has a shut-off state and a throttling state; the second valve core 52 and the valve island 7 constitute the second valve 521, which also has a shut-off state and a throttling state; the third valve core 53 and the valve island 7 constitute the third valve 531, which has a full-open state, a shut-off state, and a throttling state; and the fourth valve core 54 and the valve island 7 constitute the fourth valve 541, which also has a full-open state and a throttling state.

[0066] Reference Figure 17 , combined Figures 1 to 16When only the passenger cabin has a cooling requirement, the thermal management system is in cooling mode, the fourth valve 541 is in the fully open state, the second valve 521 and the third valve 531 are in the closed state, the first valve 511 is in the throttling state, and the compressor 8, the fourth valve 541, the first heat exchanger 1, the first indoor heat exchanger 9, the liquid receiver 4, the first heat exchanger 2, the first valve 511 and the second indoor heat exchanger 10 are connected to form a refrigerant circuit.

[0067] In cooling mode, the refrigerant flow path is as follows: The high-temperature, high-pressure refrigerant discharged from the compressor 8 flows into the thermal management component from the third channel port 73, and then flows out of the thermal management component from the first interface 11; next, the refrigerant flowing out of the first interface 11 flows through the first indoor heat exchanger 9, and then flows into the thermal management component again from the first interface 41. At this time, the damper is closed so that the first indoor heat exchanger 9 does not exchange heat with the air, and then flows out of the thermal management component again from the seventh channel port 77; the refrigerant flowing out of the seventh channel port 77 flows into the second indoor heat exchanger 10, and the second indoor heat exchanger 10 exchanges heat with the air to achieve passenger cabin cooling; the refrigerant after exchanging heat with the air flows into the thermal management component again from the first connecting port 61, and then flows out of the thermal management component from the first port 21, and then flows into the compressor 8, which then compresses the refrigerant into high temperature and high pressure, and so on.

[0068] During the process of flowing from the third channel 73 to the first interface 11, the refrigerant flows sequentially through the fourth mounting cavity 711 where the fourth valve core 54 is located and the first flow channel of the first heat exchanger 1. In the first heat exchanger 1, the refrigerant in the first flow channel exchanges heat with the coolant in the second flow channel, and the refrigerant temperature decreases.

[0069] During the process of refrigerant flowing from the first interface 41 to the seventh channel 77, the refrigerant flows from the first interface 41 into the liquid receiver 4. After flowing through the liquid receiver 4, the liquid refrigerant is stored in the liquid receiver 4, and the gaseous refrigerant flows out of the liquid receiver 4 from the second interface 42. The gaseous refrigerant flows into the fourth channel of the first heat exchanger 2. In the first heat exchanger 2, the refrigerant in the fourth channel exchanges heat with the refrigerant in the third channel, and the temperature of the refrigerant in the fourth channel decreases. Then, the refrigerant flowing out from the fourth port 24 flows through the first valve core 51 and is throttled. Then, the refrigerant flows out of the thermal management component from the seventh channel 77.

[0070] During the process of flowing from the first connecting port 61 to the first inlet 21, the refrigerant flows into the third flow channel of the first heat exchanger 2, then exchanges heat with the refrigerant in the fourth flow channel, and then flows out of the thermal management component.

[0071] Reference Figure 18 , combined Figures 1 to 16When both the passenger compartment and the battery require cooling, the thermal management system operates in a shared cooling mode for both the passenger compartment and the battery. The connection status of the thermal management system in this shared cooling mode is largely the same as in the cooling mode, except that the second valve 521 is in a throttling state, and the coolant in the battery coolant circuit exchanges heat with the refrigerant in the refrigerant system through the second heat exchanger 3. The compressor 8, fourth valve 541, first heat exchanger 1, first indoor heat exchanger 9, receiver 4, first heat exchanger 2, first valve 511, and second indoor heat exchanger 10 are connected to form a refrigerant circuit. The compressor 8, fourth valve 541, first heat exchanger 1, first indoor heat exchanger 9, receiver 4, first heat exchanger 2, second valve 521, and second heat exchanger 3 are also connected to form a refrigerant circuit.

[0072] Specifically, the refrigerant flowing out from the fourth port 24 is divided into two flow paths: one path flows through the first valve core 51 and is throttled, then flows out of the thermal management component from the seventh channel port 77, and flows into the second indoor heat exchanger 10. The second indoor heat exchanger 10 exchanges heat with the air to achieve passenger cabin cooling, and then flows back into the thermal management component from the first connecting port 61, flowing to the third flow channel of the first heat exchanger 2; the other path flows through the second valve core 52 and is throttled, then flows into the sixth flow channel of the second heat exchanger 3. In the second heat exchanger 3, the refrigerant in the sixth flow channel exchanges heat with the coolant in the fifth flow channel, the coolant temperature decreases, and can be used for coolant batteries or motors. Then the refrigerant flows into the third flow channel of the first heat exchanger 2, exchanges heat with the refrigerant in the fourth flow channel, and then flows out of the thermal management component.

[0073] Understandably, when only the battery needs cooling, compared to the mode where the passenger cabin and battery are cooled together, switching the first valve 511 to the shut-off state is sufficient.

[0074] Reference Figure 19 , combined Figures 1 to 16 When the thermal management system is in heating mode, the fourth valve 541 is in the fully open state, the first valve 511 and the third valve 531 are in the closed state, and the second valve 521 is in the throttling state. The compressor 8, the fourth valve 541, the first heat exchanger 1, the first indoor heat exchanger 9, the liquid receiver 4, the first heat exchanger 2, the second valve 521 and the second heat exchanger 3 are connected to form a refrigerant circuit.

[0075] In heating mode, the refrigerant flow path is as follows: the high-temperature and high-pressure refrigerant discharged from the compressor 8 flows into the thermal management component from the third channel port 73, and then flows out of the thermal management component from the first interface 11; then, the refrigerant flowing out from the first interface 11 flows through the first indoor heat exchanger 9, the first indoor heat exchanger 9 exchanges heat with the air to achieve heating of the passenger cabin, and the refrigerant after exchanging heat with the air flows into the thermal management component again from the first interface 41, and then flows out of the thermal management component from the first port 21, and then flows into the compressor 8, the compressor 8 compresses the refrigerant into high temperature and high pressure, and so on.

[0076] During the process of flowing from the third channel port 73 to the first interface 11, the refrigerant flows sequentially through the fourth mounting cavity 711 where the fourth valve core 54 is located and the first flow channel of the first heat exchanger 1, but the first heat exchanger 1 does not participate in heat exchange.

[0077] During the flow from the first interface 41 to the first outlet 21, the refrigerant flows from the first interface 41 into the liquid receiver 4. After passing through the liquid receiver 4, the liquid refrigerant is stored in the liquid receiver 4, while the gaseous refrigerant flows out of the liquid receiver 4 from the second interface 42. The gaseous refrigerant flows into the fourth channel of the first heat exchanger 2. In the first heat exchanger 2, the refrigerant in the fourth channel exchanges heat with the refrigerant in the third channel, causing the temperature of the refrigerant in the fourth channel to decrease. Then, the refrigerant flows through the second valve core 52 and is throttled. Then, the refrigerant flows into the sixth channel of the second heat exchanger 3. In the second heat exchanger 3, the refrigerant in the sixth channel exchanges heat with the coolant in the fifth channel, obtaining heat from the cooling circuit. Then, the refrigerant flows into the third channel of the first heat exchanger 2, then exchanges heat with the refrigerant in the fourth channel, and then flows out of the thermal management component.

[0078] In some possible embodiments, under low-temperature heating conditions, a portion of the refrigerant at a higher temperature is introduced into the sixth channel of the second heat exchanger 3 through the branch where the third valve 531 is located, thereby achieving gas replenishment and enthalpy increase.

[0079] In some possible embodiments, the fourth valve 541 is in a throttling state to enhance the heat exchange capacity of the thermal management system.

[0080] In some possible embodiments, the thermal management system further includes a one-way valve 551, which has the function of forward conduction and reverse cut-off. The one-way valve 551 is disposed between the first connection port 61 and the second indoor heat exchanger 10, with one end of the one-way valve 551 connected to the outlet of the second indoor heat exchanger 10 and the other end connected to the first connection port 61. The one-way valve 551 allows refrigerant to flow from the second indoor heat exchanger 10 to the first connection port 61, but prevents refrigerant from flowing from the first connection port 61 to the second indoor heat exchanger 10.

The two components may only have piping between them, or they may have valves or other components in addition to piping.
