Description

Technical Field

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

[0002] A three-way ball valve is a ball valve with three flow channels on its body. In related technologies, the valve core of a three-way ball valve uses an L-shaped channel. The inlet channel connects to one of the two outlet channels by rotating the valve core. The two outlet channels are located on opposite sides of the valve core, i.e., opposite sides of the inlet channel. When this type of three-way ball valve is used in a thermal management system, the inlet channel and the two outlet channels need to be connected to a separate component. These three components are located in three directions of the three-way ball valve, resulting in a relatively large space requirement after the three-way ball valve is connected to the components. Summary of the Invention

[0003] In view of the above-mentioned problems of the related technologies, this application provides a heat exchange component that is beneficial to reducing space occupation.

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

[0005] A heat exchange assembly includes a heat exchange core and a three-way reversing device, the heat exchange core being connected to the three-way reversing device; the three-way reversing device includes a block portion and a core portion, the core portion being assembled within the block portion and rotatable; the block portion has a first channel, a second channel, a third channel, and a mounting hole, the block portion including a first surface, a second surface, and a third surface, the first surface and the second surface being located on opposite sides of the block portion, one side of the third surface being connected to the first surface, and the other side of the third surface being connected to the second surface, the opening of the first channel on the surface of the block portion being located on the first surface, the openings of the second channel and the third channel on the surface of the block portion being both located on the third surface, and the openings of the second channel and the third channel on the surface of the block portion being located on the same side of the block portion; the core portion is located within the mounting hole, the core portion having a flow channel, the second channel and the third channel not communicating within the block portion; the heat exchange core includes a first manifold, a second manifold, and a first... The heat exchange tube and the connecting tube are provided. At least a portion of the third surface is in contact with the outer surface of the first manifold. The two ends of the first heat exchange tube are connected to the first manifold and the second manifold, respectively. The two ends of the connecting tube are connected to the first manifold and the second manifold, respectively. The first manifold includes a first cavity and a second cavity, which are not connected within the first manifold. The second manifold includes a third cavity and a fourth cavity, which are not connected within the second manifold. The inner cavity of the first heat exchange tube is connected to the second cavity and the fourth cavity. The inner cavity of the connecting tube is connected to the first cavity and the third cavity. The second cavity is connected to the second channel, and the first cavity is connected to the third channel. The three-way reversing device has a first working state and a second working state. In the first working state, the first channel, the flow channel, the second channel, and the second cavity are connected. In the second working state, the first channel, the flow channel, the third channel, and the first cavity are connected.

[0006] In this application, the opening of the first channel on the surface of the block is located on the first surface, and the openings of the second and third channels on the surface of the block are located on the third surface. The openings of the second and third channels on the surface of the block are located on the same side of the block, so that the components connected to the first channel, the second channel, and the third channel can be relatively compactly distributed around the three-way reversing device, which helps to reduce the space occupied.

The second channel connects to the second cavity of the first manifold, and the third channel connects to the first cavity of the first manifold. Through the arrangement of the three-way reversing device and the connecting pipe, the pipeline connected to the third channel is integrated into the heat exchange core, making the structure of the heat exchange assembly more compact, which helps to reduce the space occupied.

[0027] The heat exchange component 100 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 may complement or combine with each other.

[0028] According to a specific embodiment of the three-way commutator 3 of this application, referring to... Figure 2 , Figure 7 and Figure 8The three-way reversing device 3 includes a block portion 31, a drive assembly 32, a transmission assembly 33, and a core portion 34, with the core portion 34 assembled within the block portion 31. The transmission assembly 33 includes a rod portion 331, one end of which is connected to the drive assembly 32, and the other end of which is connected to the core portion 34. That is, after assembly, the transmission assembly 33 is partially assembled within the drive assembly 32 and partially within the block portion 31. The drive assembly 32 can drive the rod portion 331 to rotate counterclockwise or clockwise. Because the rod portion 331 is connected to the core portion 34, the rod portion 331 will drive the core portion 34 to rotate counterclockwise or clockwise.

[0029] In this embodiment, the block portion 31 is generally a hexahedral structure, and the block portion 31 includes a first surface 310, a second surface 320, and a third surface 330, so as to... Figure 7 Taking the placement direction as an example, the first surface 310 is the upper side, the second surface 320 is the lower side, and the third surface 330 is the right side. The block part 31 includes a first groove part 314 and a second groove part 317. The block part 31 has a first channel 311, a second channel 312, a third channel 313, a mounting hole 318, and an assembly hole 316. The second channel 312 and the third channel 313 are not connected within the block part 31, and the first channel 311 can selectively connect to the second channel 312 or the third channel 313. The first channel 311, the second channel 312, the third channel 313, the mounting hole 318, and the assembly hole 316 all have openings formed on the outer surface of the block portion 31. The openings of the second channel 312 and the third channel 313 are located on the same side of the block portion 31, i.e., the third side 330. The opening of the first channel 311 is located on another side of the block portion 31, i.e., the first side 310. The opening of the assembly hole 316 is located on yet another side of the block portion 31, and the opening of the mounting hole 318 is located on yet another side of the block portion 31. The core portion 34 is assembled into the block portion 31 through the mounting hole 318, and the opening of the mounting hole 318 is sealed after the core portion 34 is placed into the block portion 31. The opening of the first channel 311 is formed on the bottom wall of the first groove portion 314, and the opening of the assembly hole 316 is formed on the bottom wall of the second groove portion 317. The first groove 314 is formed by a portion of the first surface 310 being recessed into the block portion 31, and the second groove 317 is also recessed into the block portion 31.

[0030] To facilitate the assembly of components communicating with the second channel 312 and the third channel 313, the block portion 31 also includes a mating surface 315. The mating surface 315 can be a part of the third surface 330. The mating surface 315 matches the shape of the component and is mated to the outer surface of the component. For example, the mating surface 315 is a concave arc shape, and the component is partially accommodated in the space formed by the concavity of the mating surface 315, increasing the connection area between the block portion 31 and the component and improving the stability of the connection. The openings of the second channel 312 and the third channel 313 are both formed on the mating surface 315 to facilitate communication.

[0031] Reference Figure 8 The third channel 313 includes a first sub-channel 3131, a second sub-channel 3132, and a third sub-channel 3133. One end of the third sub-channel 3133 is connected to the flow channel 341, and the other end is connected to the second sub-channel 3132. The end of the second sub-channel 3132 away from the third sub-channel 3133 is connected to the first sub-channel 3131. The end of the first sub-channel 3131 away from the second sub-channel 3132 forms an opening on the third surface 330 of the block portion 31. In this embodiment, the second channel 312, the third sub-channel 3133, and the first sub-channel 3131 are arranged in parallel. The third sub-channel 3133 and the second channel 312 are located on opposite sides of the core portion 34, respectively. The second sub-channel 3132 is partially inclined relative to the first sub-channel 3131 and partially perpendicular to the first sub-channel 3131. It is understandable that by setting a two-section second sub-channel 3132, the third sub-channel 3133 can be turned 90 degrees and connected to the first sub-channel 3131, so that the openings of the second channel 312 and the third channel 313 can be formed on the same side of the block part 31.

[0032] In some other embodiments, the second sub-channel 3132 may also be a single-segment structure, with the second sub-channel 3132 perpendicular to the first sub-channel 3131. In some other embodiments, the second sub-channel 3132 may also be a single-segment structure, with the second sub-channel 3132 inclined relative to the first sub-channel 3131.

[0033] The rod portion 331 of the transmission assembly 33 extends into the block portion 31 through the mounting channel 316, thereby connecting with the core portion 34. The portion of the rod portion 331 protruding outside the mounting channel 316 connects to the drive assembly 32, which is partially accommodated in the cavity of the second groove portion 317, thereby improving the stability of the installation between the drive assembly 32 and the block portion 31. A component communicating with the first channel 311 is partially accommodated in the cavity of the first groove portion 314, and this component is fitted or connected to the side wall of the first groove portion 314 to improve the stability of the installation.

[0034] In this embodiment, the core portion 34 is located within the mounting channel 318 and can rotate within the mounting channel 318. The core portion 34 is generally spherical and has a flow channel 341, with a first channel 311 communicating with the flow channel 341. The core portion 34 includes a first hole 342 and a second hole 343, which are perpendicularly arranged and communicate with each other. The cavities of the first hole 342 and the second hole 343 together form the flow channel 341 of the core portion 34, which is generally L-shaped. The rod portion 331 is perpendicular to both the first hole 342 and the second hole 343. It can be understood that when the rod portion 331 drives the core portion 34 to rotate, the first hole 342 and the second hole 343 both rotate counterclockwise or clockwise around the rod portion 331.

[0035] One of the first hole 342 and the second hole 343 communicates with the first channel 311, and the other communicates with the second channel 312 or the third channel 313. In this embodiment, the first channel 311, the second channel 312, and the first sub-channel 3131 are cylindrical channels, and the second channel 312 and the first sub-channel 3131 are arranged in parallel as an example. The axial extension direction of the first channel 311 is defined as the first direction, and the arrangement direction of the second channel 312 and the first sub-channel 3131 is defined as the second direction. The first direction is parallel to or coincides with the second direction, and both the second channel 312 and the first sub-channel 3131 are perpendicular to the first direction. Depending on the state of the core portion 34, when the axial extension direction of the first hole 342 is parallel to or coincides with the first direction, and the axial extension direction of the second hole 343 is perpendicular to the first direction, the first hole 342 is connected to the first channel 311, and the second hole 343 is connected to the second channel 312; when the axial extension direction of the second hole 343 is parallel to or coincides with the first direction, and the axial extension direction of the first hole 342 is perpendicular to the first direction, the second hole 343 is connected to the first channel 311, and the first hole 342 is connected to the third channel 313.

[0036] The three-way reversing device 3 has a first working state and a second working state. In the first working state, the first channel 311, the second channel 312 and the flow channel 341 are connected; in the second working state, the first channel 311, the third channel 313 and the flow channel 341 are connected.

[0037] In this embodiment, the second channel 312 is arranged parallel to the first sub-channel 3131, and the openings of the second channel 312 and the third channel 313 are located on the same surface of the block portion 31. Therefore, when the three-way reversing device 3 is assembled with other components, the components communicating with the second channel 312 and the components communicating with the third channel 313 can be assembled on the same side of the block portion 31, making the structure more compact and occupying less space after assembly. In addition, the first channel 311 is perpendicular to the first sub-channel 3131 and the third channel 313. The components communicating with the first channel 311 can be arranged close to the components communicating with the second channel 312, reducing the space occupied in the first direction, further making the structure more compact after assembly, which is beneficial to reducing the space occupied.

[0038] According to a specific embodiment of the heat exchange component 100 of this application, such as Figures 1 to 6 As shown, the heat exchange assembly 100 includes a heat exchange core 1, a liquid storage assembly 2, and a three-way reversing device 3, with the liquid storage assembly 2, the heat exchange core 1, and the three-way reversing device 3 being fixedly connected in pairs.

[0039] The heat exchange core 1 includes a first manifold 11, a second manifold 12, a second heat exchange tube 132, a first heat exchange tube 131, and a connecting pipe 14. The axial extension directions of the first manifold 11 and the second manifold 12 are parallel to or coincide with a first direction. The two ends of the second heat exchange tube 132 are connected to the first manifold 11 and the second manifold 12, respectively. The two ends of the first heat exchange tube 131 are connected to the first manifold 11 and the second manifold 12, respectively. The two ends of the connecting pipe 14 are connected to the first manifold 11 and the second manifold 12, respectively. The first manifold 11 includes a fifth cavity 113, a second cavity 112, and a first cavity 111. The fifth cavity 113, the second cavity 112, and the first cavity 111 are not connected within the first manifold 11. The second manifold 12 includes a sixth cavity 123, a fourth cavity 122, and a third cavity 121. The sixth cavity 123, the fourth cavity 122, and the third cavity 121 are not connected within the second manifold 12. The inner cavity of the second heat exchange tube 132 is connected to the fifth cavity 113 and the sixth cavity 123. The inner cavity of the first heat exchange tube 131 is connected to the second cavity 112 and the fourth cavity 122. The inner cavity of the connecting tube 14 is connected to the first cavity 111 and the third cavity 121. The fifth cavity 113 is connected to the inner cavity of the liquid storage component 2. The second cavity 112 is connected to the second channel 312. The first cavity 111 is connected to the third channel 313. The contact surface 315 of the three-way reversing device 3 is in contact with the outer wall surface of the first manifold 11. The three-way reversing device 3 is fixedly connected to the first manifold 11.

[0040] The first manifold 11 includes a first end cap 114, a second end cap 115, a first partition 116, and a second partition 117. There is at least one first partition 116 and at least one second partition 117. For ease of understanding, this embodiment uses the example of having only one first partition 116 and one second partition 117. The first end cap 114 and the second end cap 115 are located on opposite sides of the first manifold 11 in the axial direction. The first end cap 114 seals one end of the first manifold 11, and the second end cap 115 seals the other end of the first manifold 11. The first partition 116 and the second partition 117 are both located between the first end cap 114 and the second end cap 115. The first partition 116 and the second partition 117 are inserted into the first manifold 11, and the first partition 116 and the second partition 117 are spaced apart, thereby dividing the inner cavity of the first manifold 11 into three chambers. The chamber between the first end cap 114 and the first partition 116 is the fifth chamber 113, the chamber between the first partition 116 and the second partition 117 is the second chamber 112, and the chamber between the second partition 117 and the second end cap 115 is the first chamber 111. The wall of the first manifold 11 has three through holes, which correspond to the fifth chamber 113, the second chamber 112, and the first chamber 111, respectively, for communication.

[0041] The second manifold 12 includes a third end cap 124, a fourth end cap 125, a third partition 126, and a fourth partition 127. There are at least one third partition 126 and at least one fourth partition 127. For ease of understanding, this embodiment uses the example of having only one third partition 126 and one fourth partition 127. The third end cap 124 and the fourth end cap 125 are located on opposite sides of the second manifold 12 in the axial direction. The third end cap 124 seals one end of the second manifold 12, and the fourth end cap 125 seals the other end of the second manifold 12. The third partition 126 and the fourth partition 127 are both located between the third end cap 124 and the fourth end cap 125. The third partition 126 and the fourth partition 127 are inserted into the second manifold 12, and are spaced apart, thus dividing the inner cavity of the second manifold 12 into three chambers. The chamber between the third end cap 124 and the third partition 126 is the sixth chamber 123; the chamber between the third partition 126 and the fourth partition 127 is the fourth chamber 122; and the chamber between the fourth partition 127 and the fourth end cap 125 is the third chamber 121. The wall of the second manifold 12 has three through holes, corresponding to the sixth chamber 123, the fourth chamber 122, and the third chamber 121, respectively, for communication.

[0042] It should be understood that, in this embodiment, the first manifold 11 is a single pipe, and the first cavity 111, the second cavity 112, and the fifth cavity 113 are formed by separating the single pipe through the first partition 116 and the second partition 117. In some other embodiments, the first manifold 11 may include at least two pipes, each of which is sealed at both ends, and the first cavity 111, the second cavity 112, and the fifth cavity 113 may be located in independent pipes. Similarly, the second manifold 12 may also include at least two pipes, and the sixth cavity 123, the fourth cavity 122, and the third cavity 121 may be located in independent pipes.

[0043] Since the structure of the first end cap 114, the second end cap 115, the third end cap 124, the fourth end cap 125, the first partition 116, the second partition 117, the third partition 126 and the fourth partition 127 and the connection relationship between the partitions and the manifold are well known to those skilled in the art, this application will not describe them in detail.

[0044] Reference Figures 4 to 6 Both the second heat exchange tube 132 and the first heat exchange tube 131 include multiple flat tubes 13. The length of the flat tube 13 is greater than its width, the width of the flat tube 13 is greater than its thickness, and the flat tube 13 has multiple through holes arranged along the width direction of the flat tube 13. All the flat tubes 13 are arranged side by side along the thickness direction of the flat tube 13.

[0045] The connecting pipe 14 and the flat pipe 13 are arranged side by side along the thickness direction of the flat pipe 13, and the cross-sectional area of ​​the connecting pipe 14 is greater than or equal to the cross-sectional area of ​​the flat pipe 13. In this embodiment, the shape of the connecting pipe 14 is similar to that of the flat pipe 13, the length of the connecting pipe 14 is approximately the same as the length of the flat pipe 13, and the width of the connecting pipe 14 is approximately the same as the width of the flat pipe 13, but the thickness of the connecting pipe 14 is greater than the thickness of the flat pipe 13. In some other embodiments, the shape of the connecting pipe 14 and the flat pipe 13 may not be similar; for example, the outer contour of the cross-section of the connecting pipe 14 may be square, circular, or other shapes.

[0046] Reference Figure 5 The connecting pipe 14 includes at least one intermediate rib 141, which is located in the inner cavity of the connecting pipe 14. The inner cavity of the connecting pipe 14 includes at least two chambers, and the intermediate rib 141 is located between two adjacent chambers. The cross-sectional area of ​​the chambers of the connecting pipe 14 is larger than the cross-sectional area of ​​the through hole of the flat pipe 13.

[0047] Integrating the connecting pipe 14, which communicates with the third channel 313, into the heat exchange core 1, and combining it with the aforementioned three-way reversing device 3, makes the entire heat exchange assembly 100 more compact and space-saving. Making the connecting pipe 14 flat, similar in appearance to the flat tube 13, further enhances the compactness of the heat exchange assembly 100. Since the connecting pipe 14 serves only a connecting function, its fabrication is relatively simple and easy to implement.

[0048] In this embodiment, in order to reduce the heat exchange between the first heat exchange tube 131 and the connecting tube 14, the heat exchange assembly 100 also includes an intermediate plate 15. One end of the intermediate plate 15 is connected to the first manifold 11, and the other end is connected to the second manifold 12. The intermediate plate 15 is located between the first heat exchange tube 131 and the connecting tube 14, and is spaced a certain distance from both of them. This can reduce the heat exchange between the first heat exchange tube 131 and the connecting tube 14, and can also increase the strength of the heat exchange assembly 100.

[0049] Refer to 2 and Figure 3 The liquid storage assembly 2 includes a cylinder 28, a cap 25, and a one-way valve 26. The cylinder 28 is fixedly connected to the first manifold 11. The cylinder 28 has a first end 21 and a second end 22 located on opposite sides of the axial direction. The cap 25 is fixed to the first end 21 and seals one end of the liquid storage assembly 2. The second end 22 is sealed to the block portion 31 of the three-way reversing device 3. The second end 22 is at least partially accommodated in the cavity of the first groove portion 314, and the outer wall surface of the second end 22 is fitted against the side wall surface of the first groove portion 314. Optionally, the second end 22 has an external thread, and the side wall surface of the first groove portion 314 has an internal thread, and the two are fixed by threaded engagement. Optionally, they can also be brazed together.

[0050] A one-way valve 26 is located within the inner cavity of the cylinder 28 and is circumferentially sealed and fixed to the inner circumferential wall of the cylinder 28. The one-way valve 26 is spaced apart from the cover 25 and connected to the cover 25. The one-way valve 26 divides the inner cavity of the cylinder 28 into an upper chamber and a lower chamber. The inner cavity between the cover 25 and the one-way valve 26 is the upper chamber, which communicates with the fifth chamber 113. The inner cavity between the cover 25 and the second end 22 is the lower chamber, which communicates with the first channel 311. The upper and lower chambers are connected or disconnected by the valve core of the one-way valve 26. The side wall of the cylinder 28 has two through holes, which correspond to the upper and lower chambers respectively, for communication.

[0051] The cylinder 28 also includes a connecting block 23 and a fixing block 24. The connecting block 23 is positioned closer to the first end 21 than the fixing block 24. The connecting block 23 has a through hole that connects the through hole corresponding to the upper chamber and the through hole corresponding to the fifth chamber 113, thereby connecting the upper chamber and the fifth chamber 113. The connecting block 23 connects the cylinder 28 and the first manifold 11. The connecting block 23 has both connecting and fixing functions, achieving both functions with a smaller structure, which helps to occupy less space and improve the integration of the heat exchange assembly 100. The fixing block 24 is positioned closer to the second end 22 than the connecting block 23. The fixing block 24 connects the cylinder 28 and the first manifold 11. The fixing block 24 and the connecting block 23 are arranged along the axial direction of the cylinder 28, located on opposite sides of the cylinder 28 in the axial direction, thereby achieving a more stable fixation of the cylinder 28 and the first manifold 11 together. In some embodiments, the connecting block 23 and the fixing block 24 may be integrally formed with the cylinder 28, or the connecting block 23 and the fixing block 24 may be integrally formed with the first manifold 11.

[0052] In some other embodiments, the liquid storage component 2 can be connected to the first manifold 11 via a pipeline, or it can be connected to the three-way reversing device 3 via a pipeline, which is not limited in this application.

[0053] The liquid storage assembly 2 may also include a filter drying device 27. The function of the filter drying device 27 is to dry and filter the refrigerant entering the lower chamber, thereby removing moisture and impurities from the refrigerant, ensuring the quality of the refrigerant, and improving the quality of the refrigerant circulation. The filter drying device 27 may include a cavity and a drying particle structure filled in the cavity. Through holes may be formed on the outer wall of the cavity of the filter drying device 27, and a mesh structure is provided at the through holes. The mesh structure can filter impurities in the refrigerant, and the drying particle structure can absorb moisture. The specific structure and working principle of the filter drying device 27 are well known to those skilled in the art, and this application will not elaborate on them further. In some other embodiments, the cylinder 28 may have its own filter drying core.

[0054] When the three-way reversing device 3 is in the first working state, the one-way valve 26 is in the conducting state, and the fifth chamber 113, the upper chamber, the lower chamber, the first channel 311, the second channel 312 and the second chamber 112 are connected; when the three-way reversing device 3 is in the second working state, the one-way valve 26 is in the closed state, the upper chamber and the lower chamber are not connected, the fifth chamber 113 and the second chamber 112 are not connected, and at this time the heat exchange assembly 100 is connected to the outside, the lower chamber, the first channel 311, the third channel 313 and the first chamber 111.

[0055] The heat exchange assembly 100 also includes a four-way device 4, which includes a coil assembly 42 and a base 41. The base 41 is fixedly connected to the second manifold 12, and the coil assembly 42 is fixedly connected to the base 41, with a portion of the coil assembly 42 located within the base 41. To facilitate the assembly and fixation of the base 41 and the second manifold 12, the base 41 includes a first sidewall 411. The shape of the first sidewall 411 matches the shape of the outer wall of the second manifold 12, and the first sidewall 411 is attached to the outer wall of the second manifold 12. For example, the first sidewall 411 is recessed in a direction away from the second manifold 12, i.e., the first sidewall 411 is an inwardly concave arc shape. The pipe wall portion of the second manifold 12 is accommodated within the space formed by the inward concavity of the first sidewall 411, increasing the connection area between the base 41 and the second manifold 12 and improving the stability of the connection.

[0056] The base 41 is generally hexahedral in structure. The base 41 has a first channel 412, a second channel 413, a third channel 414, a fourth channel 415, and a connecting channel 416. The first channel 412, the second channel 413, and the third channel 414 are all connected to the connecting channel 416. The first channel 412, the second channel 413, the third channel 414, the fourth channel 415, and the connecting channel 416 are all formed with openings on the outer surface of the base 41. The openings of the first channel 412 and the second channel 413 are located on the first side wall 411, the opening of the third channel 414 is located on the other side wall, the opening of the fourth channel 415 is located on yet another side wall, and the opening of the connecting channel 416 is located on yet yet another side wall. The first channel 412 communicates with the fourth cavity 122, the second channel 413 communicates with the third cavity 121, and the third channel 414 and the fourth channel 415 communicate with the outside of the heat exchange assembly 100, respectively. The four-way device 4 includes a seal 417, which is at least partially accommodated in the connecting channel 416 and blocks the opening of the connecting channel 416.

[0057] In this embodiment, the axial extension direction of the connecting channel 416 is parallel to or coincides with the first direction. The first channel 412 and the second channel 413 are parallel and spaced apart. The connecting channel 416 is perpendicular to the first channel 412 and the second channel 413. The third channel 414 is perpendicular to the first channel 412, the second channel 413, the fourth channel 415, and the connecting channel 416. The connecting channel 416 is parallel to the fourth channel 415. The coil assembly 42 controls whether the connecting channel 416 and the fourth channel 415 are connected or not connected. The coil assembly 42, in cooperation with the base 41, can control the opening degree of the connection between the connecting channel 416 and the fourth channel 415. It is understood that the coil assembly 42 and the base 41 form an expansion valve, wherein the first channel 412 is the inlet channel and the fourth channel 415 is the outlet channel. The structural design of the expansion valve is well known to those skilled in the art and will not be described in detail here.

[0058] In this application, the openings of the first channel 412 and the second channel 413 are both located on the first side wall 411. The first side wall 411 is in contact with the second manifold 12. Combined with the three-way reversing device 3 and the connecting pipe 14, the refrigerant in the fourth cavity 122 and the refrigerant in the third cavity 121 can both flow out of the heat exchange assembly 100 through the third channel 414, or flow out of the heat exchange assembly 100 through the fourth channel 415 after the refrigerant flow rate is regulated by the coil assembly 42. This makes the heat exchange assembly 100 highly integrated, compact in structure, and occupies less space.

[0059] The heat exchange assembly 100 also includes a first connector 5 and a second connector 6. The first connector 5 is fixedly connected to the cylinder 28 of the liquid storage assembly 2, and is used to connect the liquid storage assembly 2 to other components, thereby enabling communication between the inner cavity of the liquid storage assembly 2 and the inner cavities of other components. The second connector 6 is fixedly connected to the second manifold 12, and is used to connect the second manifold 12 to other components, thereby enabling communication between the inner cavity of the second manifold 12 and the inner cavities of other components. The first connector 5 has a through hole that connects to the outside of the heat exchange assembly 100 and a through hole on the cylinder 28 corresponding to the lower cavity. The second connector 6 has a through hole that connects to the outside of the heat exchange assembly 100 and a through hole on the second manifold 12 corresponding to the sixth cavity 123.

[0060] According to the second embodiment of the heat exchange component 100 of this application, this embodiment has a structure that is substantially the same as that of the first embodiment of the heat exchange component 100, the difference being: (Referring to...) Figure 11 and Figure 12 The heat exchange assembly 100 does not include the four-way device 4, but includes a third connector 7 and a fourth connector 8. Both the third connector 7 and the fourth connector 8 are fixedly connected to the second manifold 12, respectively, for connecting the second manifold 12 to other components. The third connector 7 has a through hole for connecting the fourth chamber 122 to the outside of the heat exchange assembly 100, and the fourth connector 8 has a through hole for connecting the third chamber 121 to the outside of the heat exchange assembly 100. Depending on the application of the heat exchange assembly 100 in the thermal management system, the outlets of the third connector 7 and the fourth connector 8 can be connected to the same expansion valve via pipelines, or respectively to an expansion valve, making the heat exchange assembly 100 suitable for different thermal management system structures and applicable to a wide range of scenarios. In this embodiment, the structures of the first connector 5, the second connector 6, the third connector 7, and the fourth connector 8 are largely the same, and the connector structures are well known to those skilled in the art; therefore, they will not be described in detail here.

[0061] According to the third embodiment of the heat exchange component 100 of this application, this embodiment has a structure that is substantially the same as that of the first embodiment of the heat exchange component 100, the difference being: Referring to Figures 13 to 15The structure of the first connector 5 is different. In this embodiment, the first connector 5 integrates a valve core of a one-way device, and the first connector 5 has a one-way conduction function. Specifically, the first connector 5 includes a main body 51, a valve core 52 and a plug 53. The main body 51 is fixedly connected to the cylinder 28 of the liquid storage assembly 2.

[0062] The valve core 52 is located inside the main body 51 and within the through hole of the first connector 5. The valve core 52 controls the unidirectional flow of refrigerant from the outside of the heat exchange assembly 100 to the inside of the cylinder 28, and stops it in the opposite direction. To facilitate the assembly of the first connector 5, the liquid storage assembly 2, and other components, and to improve the integration of the heat exchange assembly 100, the through hole of the first connector 5 is approximately "Z"-shaped. The liquid storage assembly 2 and other components are respectively assembled on the left and right sides of the first connector 5, with relatively large usable space, making assembly convenient.

[0063] To facilitate the installation of the valve core 52, the first connector 5 has a process hole (not shown in the figure) that is closed at one end and open at the other. The plug 53 blocks the open end of the process hole. At least part of the plug 53 is located inside the main body 51. The plug 53 is sealed to the main body 51 and supports and fixes the valve core 52. The plug 53 can be used to limit the axial displacement of the valve core 52 while sealing the process hole.

[0064] In this embodiment, when the three-way reversing device 3 is in the first working state, the first connecting member 5 is in the closed state, the one-way valve 26 of the liquid storage component 2 is in the open state, the upper chamber and the lower chamber of the liquid storage component 2 are connected, the fifth chamber 113 is connected to the upper chamber, and the lower chamber of the liquid storage component 2 is connected to the second chamber 112 through the three-way reversing device 3. At this time, the outside of the heat exchange component 100 cannot be connected to the lower chamber of the liquid storage component 2 through the first connecting member 5. When the three-way reversing device 3 is in the second working state, the first connecting member 5 is in the open state, the one-way valve 26 of the liquid storage component 2 is in the closed state, the upper chamber and the lower chamber of the liquid storage component 2 are not connected, the lower chamber of the liquid storage component 2 is connected to the first chamber 111 through the three-way reversing device 3, and the outside of the heat exchange component 100 is connected to the lower chamber of the liquid storage component 2 through the first connecting member 5.

[0065] In some thermal management systems, a liquid storage device is connected in series in both the heating and cooling circulation loops. This is used to remove moisture and impurities from the refrigerant, ensuring refrigerant quality and improving the quality of the refrigerant circulation. However, the heating and cooling modes do not operate simultaneously. Therefore, the system design can separate the refrigerant flow paths in the cooling and heating modes, allowing them to flow through the same liquid storage device. This reduces the number of components in the system and simplifies its structure. However, using the same liquid storage device for both heating and cooling modes may lead to refrigerant backflow. If backflow occurs, some refrigerant will be stored in components that do not participate in heat exchange, reducing the amount of refrigerant flowing in the system, which is detrimental to system operation. Related technologies require at least two unidirectional devices to prevent refrigerant backflow. The heat exchange assembly 100 in this application includes a liquid storage assembly 2 integrating a one-way valve 26 and a filter drying device 27, and a first connector 5 integrating a valve core of the one-way device and communicating with the inner cavity of the liquid storage assembly 2. This can be used to reduce the possibility of refrigerant backflow. The one-way valve 26 is disposed inside the cylinder 28, and the core part 52 is disposed inside the first connector 5. In addition, the first connector 5 can also be used as a connecting pressure plate for the heat exchange assembly 100 to connect with pipelines or components, which helps to save system pipeline components and makes the system structure more compact, which is conducive to miniaturization.

[0066] According to the fourth embodiment of the heat exchange component 100 of this application, this embodiment has a structure that is substantially the same as that of the first embodiment of the heat exchange component 100, the difference being: Referring to Figure 16 The heat exchange assembly 100 does not include the four-way device 4, but includes a third connector 7 and a fourth connector 8. Both the third connector 7 and the fourth connector 8 are fixedly connected to the second manifold 12 and are used to connect the second manifold 12 and other components, respectively. The third connector 7 is provided with a through hole to connect the fourth cavity 122 and the outside of the heat exchange assembly 100. The fourth connector 8 is provided with a through hole to connect the third cavity 121 and the outside of the heat exchange assembly 100. The structure of the first connector 5 is the same as that of the first connector 5 in the third embodiment of the heat exchange assembly 100.

[0067] This application repeatedly mentions "the exterior of the heat exchange component 100" and "other components." It is important to understand that when the heat exchange component 100 is used in a thermal management system, it will be connected to many components; that is, there are multiple external spaces connected to the heat exchange component 100. The repeated use of "the exterior of the heat exchange component 100" in this application can refer to the same location or different locations; similarly, the repeated use of "other components" can refer to the same location or different locations; and the repeated use of "the exterior of the heat exchange component 100" and "other components" can also refer to the same location, depending on the specific application of the heat exchange component 100 in the thermal management system.

[0068] This application also provides a thermal management system, referring to... Figure 17 Taking the structure of the heat exchange component 100 as an example of the third embodiment, the thermal management system includes the heat exchange component 100, compressor 200, three-way valve assembly 300, indoor condenser 400, first flow regulating device 500, indoor evaporator 600 and outdoor evaporator 700.

[0069] In this embodiment, the heat exchange assembly 100 is formed by integrating an outdoor condenser 101, a liquid receiver 102, a three-way reversing device 3, a subcooled condenser 103, a communicating vessel 104, a first one-way element 105, a second one-way element 106, and a four-way device 4. The outdoor condenser 101 functions as follows: the fifth chamber 113 of the first manifold 11, the second heat exchange tube 132, and the sixth chamber 123 of the second manifold 12. The liquid receiver 102 functions as the lower chamber of the liquid receiver assembly 2 and the filter drying device 27. The subcooled condenser 103 functions as the second chamber 112 of the first manifold 11, the fourth chamber 122 of the second manifold 12, and the first heat exchange tube 131. The communicating vessel 104 functions as the first chamber 111 of the first manifold 11, the third chamber 121 of the second manifold 12, and the communicating pipe 14. The first one-way element 105 functions as the one-way valve 26. The second one-way element 106 functions as the first connector 5. The three-way valve assembly 300 controls the flow of refrigerant from the compressor 100 to the outdoor condenser 101 or to the indoor condenser 400 according to the different system operating conditions. Optionally, the three-way valve assembly 300 can be a three-way ball valve or a combination of two shut-off valves.

[0070] The thermal management system includes heating mode and cooling mode, and heating mode and cooling mode cannot be executed at the same time.

[0071] In cooling mode, the three-way valve assembly 300 controls the flow of refrigerant from the compressor 100 to the outdoor condenser 101. The first flow regulating device 500 is in a throttling state, and the four-way device 4 is in a throttling or shut-off state. The second connector 6, which is connected to the sixth chamber 123, serves as the refrigerant inlet of the heat exchange assembly 100, and the four-way device 4 serves as the refrigerant outlet of the heat exchange assembly 100. The three-way reversing device 3 is in its first working state, that is, the fifth chamber 113 is connected to the second chamber 112 through the three-way reversing device 3. Taking the four-way device 4 in the shut-off state as an example, the compressor 200, the three-way valve assembly 300, the heat exchange assembly 100, the first flow regulating device 500, and the indoor evaporator 600 in the thermal management system are sequentially connected to form a refrigerant circuit.

[0072] Specifically, the high-temperature, high-pressure refrigerant from compressor 200 enters heat exchange assembly 100 through second connector 6, where it condenses and releases heat in outdoor condenser 101. First one-way element 105 is in the conducting state, and the refrigerant flows into receiver 102 for filtration and drying. In receiver 2, one-way valve 26 is in the conducting state, allowing refrigerant to flow from the upper chamber to the lower chamber via one-way valve 26. In the lower chamber, it flows through filter-drying device 27 for filtration and drying before flowing out. The refrigerant flowing out of receiver 102 is redirected by three-way reversing device 3 and enters subcooled condenser 103 for further condensation and heat release. It then flows out of heat exchange assembly 100 through third channel 414 of four-way device 4, and after being throttled and depressurized by first flow regulating device 500, it enters indoor evaporator 600. In indoor evaporator 600, it exchanges heat with the air, absorbing heat to cool it down, thus achieving the purpose of refrigeration. Finally, it returns to compressor 200, and the cycle continues. In cooling mode, the heat exchange assembly 100 functions as both an outdoor condenser 101 and a subcooling condenser 103, while also drying, filtering, and storing the refrigerant. After the refrigerant flows into the lower chamber of the liquid receiver 2, the refrigerant cannot flow out of the heat exchange assembly 100 from the first connector 5 because the first connector 5 is in a closed state, thus reducing the possibility of refrigerant backflow. When the first connector 5 of the heat exchange assembly 100 does not have a one-way shut-off function, a device with a one-way shut-off function can be connected to the outside of the first connector 5 to achieve the above functions.

[0073] In some other embodiments, the refrigerant flowing out of the subcooled condenser 103 can be divided into two paths. One path flows directly out of the heat exchange assembly 100 from the third channel 414 of the four-way device 4, enters the indoor evaporator 600 after being throttled and depressurized by the first flow regulating device 500, and then returns to the compressor 200. The other path flows out of the heat exchange assembly from the fourth channel 415 of the four-way device 4. In the four-way device 4, the refrigerant enters the fourth channel 415 after being throttled and depressurized by the coil assembly from the connecting channel 416. Then, the refrigerant flows out of the heat exchange assembly 100 from the fourth channel 415 and enters the outdoor evaporator 700. In the outdoor evaporator 700, it exchanges heat with the air or coolant circuit 800, absorbs heat from the air or coolant circuit 800 to cool it down, and finally returns to the compressor 200.

[0074] In heating mode, the three-way valve assembly 300 controls the flow of refrigerant from the compressor 100 to the indoor condenser 400. The first flow regulating device 500 is in the off state, the four-way device 4 is in the throttling state, the first connecting piece 5 serves as the refrigerant inlet of the heat exchange assembly 100, the four-way device 4 serves as the refrigerant outlet of the heat exchange assembly 100, and the three-way reversing device 3 is in the second working state, that is, the first chamber 111 is connected to other components through the three-way reversing device 3. In the thermal management system, the compressor 200, the three-way valve assembly 300, the indoor condenser 400, the heat exchange assembly 100, and the outdoor evaporator 700 are sequentially connected to form a refrigerant circuit.

[0075] Specifically, the high-temperature, high-pressure refrigerant from compressor 200 flows into indoor condenser 400, where it condenses and releases heat, heating the air to achieve the purpose of heating. Then, it enters heat exchange assembly 100 through first connector 5. At this time, second one-way element 106 is in a conductive state, and the refrigerant flows into receiver 102 for filtration and drying. After passing through the reversing action of three-way reversing device 3, the refrigerant flows from the third channel 313 of three-way reversing device 3 into communicating vessel 104. The refrigerant flowing out of communicating vessel 104 enters four-way device 4, where it is throttled and depressurized before flowing out of heat exchange assembly 100. In four-way device 4, the refrigerant enters the fourth channel 415 through communicating channel 416, achieving throttling and depressurization during this process. The refrigerant flowing out of four-way device 4 enters outdoor evaporator 700, where it exchanges heat with air or coolant circuit 800, absorbing heat from the air or coolant circuit 800 to cool it down. Finally, it returns to compressor 200, and the cycle continues. In heating mode, the outdoor condenser 101 and subcooled condenser 102 of the heat exchange assembly 100 do not participate in heat exchange. They dry, filter and store the refrigerant in the lower chamber of the liquid storage assembly 2. After the refrigerant flows into the lower chamber, the one-way valve 26 is in the closed state, so the refrigerant cannot flow into the upper chamber and then into the fifth chamber 113 from the one-way valve 26, thereby reducing the possibility of refrigerant backflow.

[0076] In some other embodiments, the refrigerant flowing out of the communicating vessel 104 can be divided into two paths. One path flows directly out of the heat exchange component from the third channel 414 of the four-way device 4, enters the indoor evaporator 600 after being throttled and depressurized by the first flow regulating device 500, and then returns to the compressor 200. The indoor evaporator 600 is located on the upwind side of the indoor condenser 400. The air first passes through the indoor evaporator 600 to reduce humidity, and then is heated by the indoor condenser 400 before being blown into the passenger cabin to achieve the purpose of heating and dehumidification. The other path flows out of the heat exchange component 100 from the fourth channel 415 of the four-way device 4. In the four-way device 4, the refrigerant enters the fourth channel 415 after being throttled and depressurized by the communicating channel 416, and then flows out of the heat exchange component 100 from the fourth channel 415 to the outdoor evaporator 700, and then returns to the compressor 200. At the outdoor evaporator 700, it can exchange heat with the coolant circuit 800 to achieve cooling of the battery assembly or motor assembly.

[0077] This application integrates an outdoor condenser 101, a liquid receiver 102, a subcooled condenser 103, a communicating vessel 104, a first one-way element 105, a second one-way element 106, a three-way reversing device 3, and a four-way device 4 to form a heat exchange assembly 100. The liquid receiver 102 and the first one-way element 105 are integrated to form a liquid receiver assembly 2, and the second one-way element 106 is integrated to the first connector 5. During both cooling and heating, the refrigerant can be filtered, dried, and stored in the liquid receiver assembly 2. During cooling and heating, the refrigerant in the lower chamber is affected by the first one-way element... Both 105 and the second unidirectional element 106 are unidirectional flow, reducing the possibility of backflow. The pipe connections between the outdoor condenser 101 and the first unidirectional element 105, the first unidirectional element 105 and the liquid receiver 102, the second unidirectional element 106 and the liquid receiver 102, the liquid receiver 102 and the three-way reversing device 3, and the three-way reversing device 3 and the subcooled condenser 103 are eliminated. A connecting device 104 and a four-way device 4 are also provided to reduce the space occupied by the heat exchange components and simplify the system structure. The system is more compact and conducive to system miniaturization.
