Description

Technical Field

[0001] This application relates to the field of heat exchange technology, and in particular to a manifold assembly and heat exchanger. Background Technology

[0002] Heat exchangers, also known as heat exchangers, are widely used in heat exchange systems (such as air conditioning systems). Heat exchangers can be used for heat exchange between a heat exchange medium and outside air, or for heat exchange between two heat exchange media.

[0003] Air exists inside the heat exchanger, which is difficult to expel with the flow of the heat exchange medium. This air occupies part of the heat exchanger's internal cavity, reducing its size. In related technologies, in addition to the outlet pipe for the heat exchange medium, the heat exchanger also has an exhaust pipe. The cavity of the exhaust pipe is connected to the inner cavity of the heat exchanger's manifold. The exhaust pipe is connected to a pipeline, through which air is transported to the pipeline and then to other parts, thus expelling the air from the heat exchanger. The exhaust pipe and the manifold form a manifold assembly. The heat exchanger's manifold needs an opening for installing the exhaust pipe, and the connections between the exhaust pipe and the manifold, the pipeline and the exhaust pipe, and the pipeline and other components all require consideration of sealing. Therefore, the structure of the manifold assembly and the heat exchanger is relatively complex. Summary of the Invention

[0004] In view of the above-mentioned problems in the related technologies, this application provides a flow collector and heat exchanger with a relatively simple structure.

[0005] To achieve the above objectives, this application adopts the following technical solution: a current collection assembly, including a first current collection element and a piping, the first current collection element including an outlet pipe, the lumen of the outlet pipe communicating with the inner cavity of the first current collection element, the piping including an inlet end and an outlet end, the inlet end being located in the inner cavity of the first current collection element, the outlet end being at least partially located in the lumen of the outlet pipe, the inner cavity of the piping communicating with the lumen of the outlet pipe, and the inner cavity of the piping communicating with the inner cavity of the first current collection element.

[0006] In this application, a portion of the piping is located within the inner cavity of the first manifold, and another portion is located within the cavity of the outlet pipe. The inner cavity of the piping connects the inner cavity of the first manifold and the cavity of the outlet pipe. When the manifold assembly is in operation, the fluid in the inner cavity of the first manifold is guided to the cavity of the outlet pipe through the piping. The fluid flows out of the manifold assembly along with the heat exchange medium flowing out of the outlet pipe. The piping and the outlet pipe share a common outlet, thereby simplifying the structure of the manifold assembly.

[0007] To achieve the above objectives, this application also adopts the following technical solution: a heat exchanger, the heat exchanger including a heat exchange tube and the above-mentioned manifold assembly, the heat exchange tube being sealed to the first manifold assembly, and the inner cavity of the heat exchange tube communicating with the inner cavity of the first manifold assembly.

[0008] In this application, when the heat exchanger is in operation, the fluid in the inner cavity of the first manifold is guided to the cavity of the outlet pipe through the piping. The fluid flows out of the heat exchanger together with the heat exchange medium flowing out of the outlet pipe. The piping and the outlet pipe share the same outlet, thereby simplifying the structure of the heat exchanger. Attached Figure Description

[0025] The heat exchanger 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.

[0026] According to a specific embodiment of the heat exchanger of this application, such as Figures 1 to 9 As shown, the heat exchanger includes a first collector 1, a second collector 2, and a heat exchange core 3. One end of the heat exchange core 3 is connected to the first collector 1, and the other end is connected to the second collector 2. The inner cavity of the heat exchange core 3 is connected to the inner cavity of the first collector 1 and the inner cavity of the second collector 2. The first collector 1 is located on one side of the length direction of the heat exchange core 3, and the second collector 2 is located on the other side of the length direction of the heat exchange core 3.

[0027] This embodiment uses a two-pass heat exchanger as an example for explanation. Specifically, the first manifold 1 has a first cavity 10 and a second cavity 20, which are not interconnected within the first manifold 1. The second manifold 2 has a third cavity 30. The heat exchange core 3 includes heat exchange tubes, which include a plurality of first heat exchange tubes 31 and a plurality of second heat exchange tubes 32. The plurality of first heat exchange tubes 31 are arranged along the length direction of the first manifold 1, and the plurality of second heat exchange tubes 32 are arranged along the length direction of the first manifold 1. The thickness directions of the first heat exchange tubes 31 and the second heat exchange tubes 32 are parallel to or coincide with the length direction of the first manifold 1. The inner cavity of each first heat exchange tube 31 connects the first cavity 10 and the third cavity 30, and the inner cavity of each second heat exchange tube 32 connects the second cavity 20 and the third cavity 30. Side plates 33 may be provided on the outermost sides of both sides in the thickness direction of the heat exchange core 3 to protect the heat exchange core 3. Heat exchange elements 34 may be provided between two adjacent first heat exchange tubes 31, between two adjacent second heat exchange tubes 32, between the first heat exchange tube 31 and the side plate 33, and between the second heat exchange tube 32 and the side plate 33, to enhance the heat exchange effect of the heat exchanger and improve the strength of the heat exchanger.

[0028] The first manifold 1 includes a first component 11, a second component 12, and a first sealing component 13. The first sealing component 13 is located between the first component 11 and the second component 12, and the first sealing component 13 abuts against the first component 11 and the second component 12 respectively. The heat exchange core 3 is sealed to the second component 12. In this embodiment, the first component 11 is made of plastic, the second component 12 is made of metal, and the first sealing component 13 is made of elastic material. The first component 11 and the second component 12 are installed together by a flanged and crimped process. The first sealing component 13 is used to form a sealing effect at the connection between the first component 11 and the second component 12, thereby forming a relatively sealed space in the first manifold 1 and isolating the first cavity 10 and the second cavity 20 from each other within the first manifold 1.

[0029] The first component 11 includes a first recessed portion 113, a second recessed portion 114, and a spacer portion 115. The spacer portion 115 is located between the cavity of the first recessed portion 113 and the cavity of the second recessed portion 114. The spacer portion 115 is both a part of the sidewall of the first recessed portion 113 and a part of the sidewall of the second recessed portion 114. The first cavity 10 is located between the bottom wall of the first recessed portion 113 and the second component 12, and the second cavity 20 is located between the bottom wall of the second recessed portion 114 and the second component 12.

[0030] Reference Figure 3 and Figure 4The first sealing element 13 includes a second segment 133, a third segment 134, a fourth segment 135, a fifth segment 136, and a first segment 137. In this embodiment, the second segment 133, the third segment 134, the fourth segment 135, the fifth segment 136, and the first segment 137 are integral structures. The second segment 133 and the fourth segment 135 both extend along the length direction of the first collector 1, and are located on opposite sides of the width direction of the first collector 1. The third segment 134 and the fifth segment 136 both extend along the width direction of the first collector 1, and are located on opposite sides of the length direction of the first collector 1. The first segment 137 extends along the length direction of the first collector 1, with one end connected to the middle region of the third segment 134 and the other end connected to the middle region of the fifth segment 136. The first segment 137 is located between the second segment 133 and the fourth segment 135. The third segment 134 connects one end of the second segment 133 and one end of the fourth segment 135, and the fifth segment 136 connects the other end of the second segment 133 and the other end of the fourth segment 135. It can be understood that the second segment 133, the third segment 134, the fourth segment 135, and the fifth segment 136 are connected sequentially, forming a roughly square ring structure. The second segment 133, the third segment 134, the fourth segment 135, the fifth segment 136, and the first segment 137 together constitute... Shape structure.

[0031] After the first manifold 1 is assembled, the second segment 133, a portion of the third segment 134, a portion of the fifth segment 136, and the first segment 137 are arranged around the opening of the first recess 113 to prevent the heat exchange medium in the first cavity 10 from flowing out of the heat exchanger through the gap between the first piece 11 and the second piece 12. The fourth segment 135, another portion of the third segment 134, another portion of the fifth segment 136, and the first segment 137 are arranged around the opening of the second recess 114 to prevent the heat exchange medium in the second cavity 20 from flowing out of the heat exchanger through the gap between the first piece 11 and the second piece 12. The spacer portion 115 of the first piece 11 presses against the first segment 137 to form a seal, which is used to isolate the first cavity 10 and the second cavity 20.

[0032] Positioning structures 131 are provided at the connections between the second segment 133 and the third segment 134, the third segment 134 and the fourth segment 135, the fourth segment 135 and the fifth segment 136, and the second segment 133 and the fifth segment 136. These four positioning structures 131 are located at the four corners of the first sealing element 13. Since the first sealing element 13 is made of an elastic material, which is relatively soft and elastic, it is easily curled or bent without external force. The positioning structures 131 are used to initially position the first sealing element 13 before assembling the first part 11 and the second part 12, preventing deformation of the first sealing element 13 from causing it to shift and thus preventing the first manifold 1 from achieving a good sealing effect after installation. Optionally, the positioning structure 131 has positioning holes 132, which cooperate with positioning pins on the tooling to achieve initial positioning of the first sealing element 13.

[0033] The first sealing element 13 is made of an elastic material; optionally, it is made of rubber. The first sealing element 13 is deformed by the compression of the first element 11 and the second element 12, thereby achieving a sealing effect. (Refer to...) Figure 10 and Figure 11The second segment 133, the third segment 134, the fourth segment 135, and the fifth segment 136 all have circular cross-sections in their free state, and waist-shaped cross-sections after compression. Each of these segments has a plane that abuts against the first component 11, and each also has a plane that abuts against the second component 12. All these planes are sealing surfaces. The first segment 137 includes a main body 1370 and several protruding ribs 1371. The protruding ribs 1371 extend outward from the main body 1370 and extend along the length direction of the first collector 1. The length of the protruding ribs 1371 is the same as the length of the first segment 137. In its free state, the first segment 137 has a recess 1372 formed between two adjacent protrusions 1371. The space between the two adjacent protrusions 1371 is the inner cavity of the recess 1372. The protrusions 1371 on both sides of the recess 1372 are the sidewalls of the recess 1372, and the bottom wall of the recess 1372 is the outer wall of the main body 1370. The recesses 1372 include a first recess 1375 and a second recess 1376. During the sealing process, the protrusions 1371 on both sides of the first recess 1375 move away from each other. The first recess 1375 may become straight or remain curved after the first segment 137 is compressed. The protrusions 1371 on both sides of the second recess 1376 move closer to each other, and the inner cavity of the second recess 1376 becomes smaller after the first segment 137 is compressed. It should be understood that "free state" in this application refers to the state in which the first seal 13 is freely placed and not compressed. "Compressed state" in this application refers to the state in which an external force compresses the first seal 13.

[0034] In some specific embodiments, reference is made to Figure 8 , Figure 10 as well as Figure 11 The first segment 137 includes four protruding ridges 1371, which are arranged circumferentially around the first segment 137. Each ridge includes two first protruding ridges 1373 and two second protruding ridges 1374. After the first segment 137 is compressed, the two first protruding ridges 1373 abut against the spacer portion 115, and the two second protruding ridges 1374 abut against the second piece 12. Correspondingly, the first segment 137 has four recessed portions 1372 in its free state. In this embodiment, in the free state, the cross-section of the bottom wall of the recessed portion 1372 is approximately arc-shaped. The cross-section of the first segment 137 in its free state is approximately "X"-shaped, and the cross-section after compression is approximately "I"-shaped. Figure 10Taking the placement direction as an example, the first segment 137 includes the upper side facing the first piece 11, the lower side facing the second piece 12, the left side facing the second segment 133, and the right side facing the fourth segment 135. In the free state, the openings of the four recesses 1372 of the first segment 137 face the upper, lower, left, and right sides, respectively. The four recesses 1372 include two first recesses 1375 and two second recesses 1376. The recesses 1372 with openings facing the upper and lower sides are the first recesses 1375, and the recesses 1372 with openings facing the left and right sides are the second recesses 1376. The two first convex ridges 1373 are located on both sides of one of the first recesses 1375, and the two second convex ridges 1374 are located on both sides of the other first recess 1375. One side of the second recess 1376 is a first convex ridge 1373, and the other side is a second convex ridge 1374.

[0035] During the assembly of the first piece 11 and the second piece 12, the two first protruding ridges 1373 first contact the spacer 115. As the first piece 11 and the second piece 12 gradually approach each other, one of the two first protruding ridges 1373 that are in contact with the spacer 115 shifts to the left and deforms, while the other shifts to the right and deforms. The bottom wall of the first recess 1375 with its opening facing upward gradually stretches. Depending on the design of the first sealing element 13, after the sealing effect is formed, the bottom wall of the first recess 1375 can become completely straight, that is, the bottom wall of the first recess 1375 contacts or presses against the spacer 115. At this time, the bottom wall of the first recess 1375 is not under force, or is only under a small force; or it can still have a certain degree of curvature, that is, there is a gap between the bottom wall of the first recess 1375 and the spacer 115. Similarly, the two second protruding ridges 1374 first contact the second piece 12. As the first piece 11 and the second piece 12 gradually approach each other, one of the two second protruding ridges 1374 in contact with the second piece 12 shifts to the left and deforms, while the other shifts to the right and deforms. The bottom wall of the first recess 1375 with its opening facing downward gradually stretches. Depending on the design of the first sealing member 13, after the sealing effect is formed, the bottom wall of the first recess 1375 can become completely straight, that is, the bottom wall of the first recess 1375 contacts or presses against the second piece 12. At this time, the bottom wall of the recess 1372 is not under force, or is only under a small force; it can also still have a certain degree of curvature, that is, there is a gap between the bottom wall of the first recess 1375 and the second piece 12. Correspondingly, the protruding ridges 1371 on both sides of the second recess 1376 with its opening facing left approach each other but do not contact each other, and the protruding ridges 1371 on both sides of the second recess 1376 with its opening facing right approach each other but do not contact each other. It is understandable that as the first piece 11 and the second piece 12 gradually approach each other, the cross-section of the first segment 137 gradually changes from "X" to "I", and a seal is gradually formed between the first piece 11 and the first sealing element 13, as well as between the second piece 12 and the first sealing element 13.

[0036] After the first piece 11 and the second piece 12 are assembled, the two first protruding ridges 1373 abut against the spacer portion 115 and form a seal, and the two second protruding ridges 1374 abut against the second piece 12 and form a seal. That is, the upper side of the first segment 137 has a double-sealing structure, and the lower side of the first segment 137 also has a double-sealing structure, thereby ensuring the reliability of the sealing effect. Since there is a recess 1372 between two adjacent protruding ridges 1371 in the free state, the rebound force of the first segment 137 after sealing can be reduced, thereby protecting the first piece 11 and reducing the possibility of deformation of the first piece 11.

[0037] In related technologies, the cross-sections of the second segment 133, the third segment 134, the fourth segment 135, the fifth segment 136, and the first segment 137 in their free state are all circular, resulting in a large rebound force after sealing. The flange of the second piece 12 presses against the periphery of the first piece 11. The second segment 133, the third segment 134, the fourth segment 135, and the fifth segment 136 are distributed around the periphery of the first piece 11. The rebound force of the second segment 133, the third segment 134, the fourth segment 135, and the fifth segment 136 interacts with the pressing force of the flange of the second piece 12, forming a good sealing effect. However, since the spacer 115 is located in the middle of the first piece 11, the compressive force of the spacer 115 on the first segment 137 is relatively small. The large rebound force of the first segment 137 will cause the spacer 115 and / or the second piece 12 to deform, thus preventing a seal from being formed at the first segment 137. In some related technologies, the clamping force of the spacer 115 is increased by setting bolt structures or snap-fit ​​structures on or beside the spacer 115, thereby improving the deformation phenomenon caused by the rebound force. However, the above method results in a larger width dimension and a more complex structure for the first collector 1, which is not conducive to the installation and manufacturing of the heat exchanger.

[0038] In this application, the structure of the first segment 137 is improved. In its free state, the first segment 137 has a protruding ridge 1371 and a recessed portion 1372, which can reduce the rebound force of the first segment 137 after compression and protect the spacer portion 115 and / or the second member 12. The upper and lower sides of the protruding ridge 1371 are both double-sealing structures, which can reduce the rebound force of the first segment 137 after compression while ensuring the sealing performance of the first seal 13.

[0039] In some other embodiments, reference is made to Figure 12 The first segment 137 includes four protruding ridges 1371, which are arranged around the circumference of the first segment 137. The cross-section of the bottom wall of the first recess 1375 is approximately straight, and the cross-section of the first segment 137 in the free state is approximately "H" shaped.

[0040] In some other embodiments, reference is made to Figure 13 The first segment 137 includes three protruding ridges 1371, which are arranged circumferentially around the first segment 137. Each of the three ridges 1371 includes two first ridges 1373 and one second ridge 1374. The first sealing member 13 is assembled with the first manifold 1. When the first segment 137 is in its free state, the two first ridges 1373 protrude towards the spacer 115, and a first recess 1375 is formed between the two first ridges 1373. The cross-section of the bottom wall of the first recess 1375 can be straight or curved. The second ridge 1374 protrudes towards the second member 12, and a second recess 1376 is formed between each of the two first ridges 1373 and the second ridge 1374. The cross-section of the first segment 137 in its free state is approximately "V" shaped. During the sealing process, the two first ridges 1373 move away from each other, while the first ridge 1373 and the second ridge 1374 move closer together. After the first piece 11 and the second piece 12 are assembled, a double-sealed structure is formed between the spacer 115 and the first segment 137, while a single-sealed structure is formed between the first segment 137 and the second piece 12. Furthermore, the second piece 12 may have a groove corresponding to the second protrusion 1374, with the second protrusion 1374 at least partially located in the groove. This groove limits the positioning of the first segment 137, ensuring the reliability of its installation and thus improving the sealing effect at the first segment 137.

[0041] In some other embodiments, the first segment 137 may be provided with a greater number of protrusions 1371. In the free state, the first segment 137 has a recess 1372 formed between two adjacent protrusions 1371. This application does not limit the number and shape of the protrusions 1371, as long as the effect of reducing the rebound force of the first segment 137 can be achieved.

[0042] In some other embodiments, the first seal 13 may further include a plurality of sixth segments, which extend along the width direction of the first manifold 1. The sixth segments connect the second segment 133 and the first segment 137, or connect the fourth segment 135 and the first segment 137, to facilitate the limiting of the first seal 13. The cross-section of the sixth segment in its free state may be the same as the cross-section of the first segment 137 or the cross-section of the second segment 133.

[0043] In some other embodiments, the cross-sections of the second segment 133, the third segment 134, the fourth segment 135, and the fifth segment 136 in their free state may be the same as the cross-section of the first segment 137, as long as the sealing requirements can be met, this application does not impose any restrictions.

[0044] In some embodiments, the first member 11 includes an annular protrusion that protrudes outward. The annular protrusion includes a first annular protrusion 116 and a second annular protrusion 117. The first annular protrusion 116 is disposed around the opening of the first recess 113, and the second annular protrusion 117 is disposed around the opening of the second recess 114. A portion of the first seal 13 is located between the first annular protrusion 116 and the second annular protrusion 117. A portion of the first annular protrusion 116 is located between the first seal 13 and the first heat exchange tube 31, and a portion of the second annular protrusion 117 is located between the first seal 13 and the second heat exchange tube 32. Specifically, the first segment 137 is located between the first annular protrusion 116 and the second annular protrusion 117. A portion of the first annular protrusion 116 is located between the second segment 133 and the first heat exchange tube 31. A portion of the first annular protrusion 116 is located between the third segment 134 and the first heat exchange tube 31. A portion of the first annular protrusion 116 is located between the fifth segment 136 and the first heat exchange tube 31. A portion of the second annular protrusion 117 is located between the third segment 134 and the second heat exchange tube 32. A portion of the second annular protrusion 117 is located between the fourth segment 135 and the second heat exchange tube 32. A portion of the second annular protrusion 117 is located between the fifth segment 136 and the second heat exchange tube 32.

[0045] The second component 12 includes a first hole 121 for inserting the first heat exchange tube 31 and a second hole 122 for inserting the second heat exchange tube 32. During processing, burrs may be generated in the first hole 121 and the second hole 122. If the first seal 13 comes into contact with these burrs, it will be damaged, thus affecting its sealing performance. This application provides a first annular protrusion 116 and a second annular protrusion 117, which can both limit the position of the first seal 13, reducing the possibility of poor sealing caused by misalignment of the first seal 13, and isolate the first seal 13 from the first hole 121 and the second hole 122, protecting the first seal 13 and ensuring its sealing effect.

[0046] Reference Figure 4 and Figure 8In some embodiments, the portion of the first annular protrusion 116 located between the first segment 137 and the first heat exchange tube 31 has a toothed structure. Specifically, this portion of the first annular protrusion 116 includes a notch 1161 and an extension 1162 located between two adjacent notches 1161, with the notches 1161 and extensions 1162 arranged alternately. The end face of the notch 1161 facing the second piece 12 is closer to the second piece 12 than the end face of the extension 1162 facing the second piece 12. After the first piece 11 and the second piece 12 are assembled, neither the end face of the notch 1161 facing the second piece 12 nor the end face of the extension 1162 facing the second piece 12 contacts the second piece 12. Similarly, the portion of the second annular protrusion 117 located between the first segment 137 and the second heat exchange tube 32 has a toothed structure. The structure of the second annular protrusion 117 is basically the same as that of the first annular protrusion 116 located between the first segment 137 and the first heat exchange tube 31, as described above. The extensions 1162 of the first annular protrusion 116 and the second annular protrusion 117 limit the first segment 137, preventing poor sealing caused by misalignment of the first segment 137.

[0047] Furthermore, the notch 1161 of the first annular protrusion 116 also has a groove recessed in the direction away from the first heat exchange tube 31, which is used to avoid the first heat exchange tube 31 and the first hole 121; the notch 1161 of the second annular protrusion 117 also has a groove recessed in the direction away from the second heat exchange tube 32, which is used to avoid the second heat exchange tube 32 and the second hole 122. This allows the first heat exchange tube 31 and the second heat exchange tube 32 to be brought closer to each other, thereby reducing the size of the heat exchanger in the width direction of the first manifold 1, which is beneficial for the miniaturization of the heat exchanger.

[0048] The first component 11 includes an inlet pipe 111 and an outlet pipe 112. The inlet pipe 111 guides the heat exchange medium into the heat exchanger, and the outlet pipe 112 guides the heat exchange medium out of the heat exchanger. The cavity of the inlet pipe 111 is connected to the first cavity 10, and the cavity of the outlet pipe 112 is connected to the second cavity 20. The first manifold 1 includes a first side 40 and a second side 50, which are located on opposite sides along the length of the first manifold 1. The inlet pipe 111 and the outlet pipe 112 are both located between the first side 40 and the second side 50, with the inlet pipe 111 and the outlet pipe 112 positioned relatively close to the second side 50. The thickness of the first manifold 1 gradually decreases along the direction from the inlet pipe 111 to the second side 50 and along the direction from the outlet pipe 112 to the second side 50. This arrangement, with its inclined surface, improves the stagnant water phenomenon in the first cavity 10 and the second cavity 20, thereby enhancing the heat exchange efficiency of the heat exchanger.

[0049] The second manifold 2 includes a third component 21, a fourth component 22, and a second sealing component 23. The second sealing component 23 is located between the third component 21 and the fourth component 22, and abuts against both the third component 21 and the fourth component 22. The heat exchange core 3 is sealed to the fourth component 22. In this embodiment, the third component 21 is made of plastic, the fourth component 22 is made of metal, and the second sealing component 23 is made of elastic material. The third component 21 and the fourth component 22 are installed together by a flanged and crimped process. The second sealing component 23 is used to create a sealing effect at the connection between the third component 21 and the fourth component 22, thereby forming a relatively sealed third cavity 30 within the second manifold 2.

[0050] Reference Figure 2 The second seal 23 is roughly "U"-shaped. The rebound force of the second seal 23 interacts with the buckling force of the flange of the fourth part 22 to form a better sealing effect. Similarly, the four corners of the second seal 23 are also provided with positioning structures to initially position the second seal 23 before the third part 21 and the fourth part 22 are assembled.

[0051] The third component 21 includes a third recessed portion 24, and a third cavity 30 is located between the bottom wall of the third recessed portion 24 and the fourth component 22. In some embodiments, the third component 21 includes a third annular protrusion 25, which is arranged around the opening of the third recessed portion 24. The second seal 23 is located between the third annular protrusion 25 and the first heat exchange tube 31, and between the third annular protrusion 25 and the second heat exchange tube 32. Similarly, the third annular protrusion 25 provided in this application can both limit the second seal 23, reducing the phenomenon of poor sealing effect caused by the displacement of the second seal 23, and isolate the second seal 23 from the hole located in the fourth component 22, protecting the second seal 23 and thus ensuring the sealing effect of the second seal 23.

[0052] When the heat exchanger is in operation, the heat exchange medium enters the first chamber 10 through the inlet pipe 111. The heat exchange medium in the first chamber 10 is distributed to several first heat exchange tubes 31, flowing along the tubes and then converging into the third chamber 30. The heat exchange medium in the third chamber 30 is distributed to several second heat exchange tubes 32, flowing along the tubes and then converging into the second chamber 20. Finally, the heat exchange medium flows out of the heat exchanger through the outlet pipe 112. During the flow of the heat exchange medium through the first and second heat exchange tubes 31 and 32, heat exchange occurs between the heat exchange medium inside the heat exchanger and the heat exchange medium outside the heat exchanger.

[0053] Reference Figures 2 to 9The heat exchanger also includes piping 14, a portion of which is located in the second cavity 20, and another portion is located in the cavity of the outlet pipe 112. In this embodiment, piping 14 is made of metal. In other embodiments, piping 14 may also be made of plastic, glass, or rubber, as long as it can serve the function of drainage. This application does not impose any restrictions.

[0054] Pipe 14 includes an inlet end 142, an outlet end 143, a first connecting portion 141, and a second connecting portion 144. The first connecting portion 141 connects to the second connecting portion 144 and is connected to the inlet end 142. The second connecting portion 144 connects the outlet end 143 and the first connecting portion 141. The inner cavity of pipe 14 includes the inner cavity of the inlet end 142, the inner cavity of the outlet end 143, the inner cavity of the first connecting portion 141, and the inner cavity of the second connecting portion 144. The inlet end 142 is disposed near the first side 40 of the first manifold 1, and at least a portion of the outlet end 143 is located in the cavity of the outlet pipe 112.

[0055] In this embodiment, the axial extension direction of the inlet pipe 111 and the axial extension direction of the outlet pipe 112 are both parallel to or coincide with the width direction of the first manifold 1. The inlet end 142 extends along the length direction of the first manifold 1, and the outlet end 143 extends along the width direction of the first manifold 1. The first connecting portion 141 extends along the length direction of the first manifold 1, connecting and communicating the relatively far-separated inlet end 142 and outlet end 143, guiding the air distributed near the first side 40 to the outlet pipe 112 located near the second side 50. The second connecting portion 144 includes a portion extending approximately along the length direction of the first manifold 1 and another portion extending approximately along the width direction of the first manifold 1. Both portions of the second connecting portion 144 are arc-shaped, completing the flow direction change within the piping 14 through the second connecting portion 144. The cross-sections of the inlet end 142, the outlet end 143, and the first connecting portion 141 are all annular, and the inlet end 142, the outlet end 143, and the first connecting portion 141 are all circular pipes. The length direction of the first collector 1 is defined as the height direction. The inlet pipe 111 and the outlet pipe 112 have the same height, while the inlet end 142 and the outlet end 143 have different heights.

[0056] In some embodiments, the thickness direction of the first manifold 1 is defined as the height direction, the inlet end 142 and the outlet end 143 have different heights, the inlet end 142 and the first connection 141 have the same height, and the second connection 144 further includes a portion extending approximately along the thickness direction of the first manifold 1. The second connection 144 is used to realize the flow direction change of the heat exchange medium in the piping 14 and adapt to the change in height difference.

[0057] In some embodiments, refer to Figures 3 to 5The free end of the inlet end 142 has an end face, and the axial extension direction of the inlet end 142 forms an angle with the end face. It can be understood that the inlet of the pipe 14 is a beveled cut, which can increase the inlet area of ​​the pipe 14, facilitate the inflow of gas and heat exchange medium, and improve exhaust efficiency.

[0058] Reference Figures 3 to 5 The heat exchanger also includes a first limiting part 119, which cooperates with the piping 14 to install and limit the piping 14, preventing the piping 14 from falling off or moving. The first limiting part 119 can be provided in the first part 11 or the second part 12, as long as it can install and limit the piping 14, this application does not limit it.

[0059] This embodiment uses the first limiting part 119 located on the first piece 11 as an example for explanation. The first limiting part 119 and the second groove part 114 are integral structures. The material of the first limiting part 119 is the same as that of the first piece 11. The first limiting part 119 extends from the bottom wall of the second groove part 114 toward the second piece 12. The extension direction of the first limiting part 119 is parallel to or coincides with the thickness direction of the first collector 1. The end of the first limiting part 119 away from the bottom wall of the second groove part 114 has a groove 1191. A portion of the pipe 14 is located in the groove cavity of the groove 1191. The groove 1191 and the pipe 14 are fitted by a radius-crossing method. The shape of the cavity of the groove 1191 matches the external shape of the pipe 14. In this embodiment, the cross-section of the pipe 14 is approximately annular, and the bottom and side walls of the groove 1191 are also arc-shaped. The outer diameter of the pipe 14 located within the groove 1191 is less than or equal to the size of the groove 1191, and the outer wall of the pipe 14 fits against the groove wall of the groove 1191. It is understood that the two side walls of the groove 1191 form two opposing claws, and the minimum distance between the two claws is less than the maximum size of the pipe 14 located within the cavity of the groove 1191. The groove 1191 encloses the pipe 14, thereby limiting the displacement of the pipe 14 along the thickness direction of the first manifold 1 and preventing the pipe 14 from falling off the first member 11. In the thickness direction of the first manifold 1, the groove depth of the groove 1191 is greater than half the size of the pipe 14 located within the cavity of the groove 1191.

[0060] The number of first limiting portions 119 is at least one, and the first limiting portions 119 cooperate with the first connecting portions 141. (Refer to...) Figures 3 to 5When there are two or more first limiting parts 119, the two or more first limiting parts 119 are arranged along the axial extension direction of the first connecting part 141. The grooves 1191 of the two or more first limiting parts 119 simultaneously limit the piping 14, which can increase the reliability of installation and protect the first connecting part 141 from bending. The grooves 1191 of the two or more first limiting parts 119 have the same height, so that the first connecting part 141 is parallel to or coincides with the length direction of the first collector 1.

[0061] In some other embodiments, when the first limiting part 119 is located on the second piece 12, the first limiting part 119 extends from the second piece 12 toward the first piece 11, and the material of the first limiting part 119 is the same as that of the second piece 12. In this case, the structure of the first limiting part 119 and the way it cooperates with the pipe 14 can be the same as described above, or other methods can be used. Optionally, the first limiting part 119 can be made of metal, and the pipe 14 can also be made of metal; the pipe 14 and the first limiting part 119 are fixedly connected by brazing.

[0062] The piping 14 also includes a protrusion 145, which extends from the pipe wall of the piping 14 toward the direction away from the pipe cavity of the piping 14. The protrusion 145 is disposed at the first connecting portion 141 and is located outside the cavity of the groove portion 1191. The protrusion 145 can be an integral structure with the pipe wall of the piping 14, or it can be a separate structure and then connected to each other. The protrusion 145 is arranged adjacent to one of the first limiting portions 119. Along the length direction of the first manifold 1, the protrusion 145 is farther away from the outlet end 143 than the adjacent first limiting portion 119, and closer to the inlet end 142 than the adjacent first limiting portion 119. On a plane perpendicular to the length direction of the first manifold 1, the projection of the protrusion 145 coincides with the projection of the adjacent first limiting portion 119. Along the length of the first manifold 1, the minimum distance between the protrusion 145 and the outlet end 143 is greater than or equal to the minimum distance between the outlet pipe 112 and the protrusion 145, while the distance between the protrusion 145 and the outlet end 143 is less than the maximum distance between the outlet pipe 112 and the protrusion 145. It is understood that the outlet end 143 and the protrusion 145 together restrict the displacement of the piping 14 along the length of the first manifold 1. In this embodiment, the protrusion 145 is approximately annular, and the maximum distance between the two groove walls of the groove 1191 is less than the outer diameter of the protrusion 145. In some other embodiments, the protrusion 145 can be a plurality of dispersed structures, distributed circumferentially along the first connecting portion 141.

[0063] Reference Figures 3 to 5The heat exchanger also includes a second limiting part 118, which cooperates with the piping 14 to limit the piping 14 and reduce the risk of the piping 14 falling off due to rotation or swing. The second limiting part 118 can be provided in the first part 11 or the second part 12, as long as it can limit the piping 14, this application does not limit it.

[0064] This embodiment uses the example of a second limiting portion 118 located on the first member 11 for explanation. The second limiting portion 118 and the second groove portion 114 are integral structures. The material of the second limiting portion 118 is the same as that of the first member 11. The second limiting portion 118 extends from the first member 11 toward the second member 12. The second limiting portion 118 is arranged close to the first side 40 and adjacent to the end of the inlet end 142. In the length direction of the first collector 1, a portion of the second limiting portion 118 is located on the side of the inlet end 142 away from the outlet end 143. On a plane perpendicular to the length direction of the first collector 1, the projection of the second limiting portion 118 coincides with the projection of the inlet end 142. In the width direction of the first manifold 1, a portion of the second limiting part 118 is located on the side of the inlet end 142 away from the outlet end 143. On a plane perpendicular to the width direction of the first manifold 1, the projection of the second limiting part 118 coincides with the projection of the inlet end 142. It can be understood that the second limiting part 118 is approximately L-shaped, and the end of the inlet end 142 is located in the L-shaped recessed space, which restricts the displacement of the pipe 14 in both the length direction and the width direction of the first manifold 1.

[0065] In some other embodiments, when the second limiting portion 118 is located in the second piece 12, the second limiting portion 118 extends from the second piece 12 toward the first piece 11, and the material of the second limiting portion 118 is the same as that of the second piece 12. Optionally, the first limiting portion 119 and the second limiting portion 118 can both be provided in the first piece 11, the first limiting portion 119 and the second limiting portion 118 can both be provided in the second piece 12, or one of the first limiting portion 119 and the second limiting portion 118 can be provided in the first piece 11 and the other in the second piece 12.

[0066] The first limiting part 119 engages with the pipe 14 via a radius fit, restricting the displacement of the pipe 14 along the thickness and width directions of the first manifold 1. The protrusion 145 engages with the first limiting part 119, the inlet end 142 engages with the second limiting part 118, and the outlet end 143 engages with the outlet pipe 112, restricting the displacement of the pipe 14 along the length direction of the first manifold 1. The pipe 14 itself is approximately L-shaped, and at least part of the outlet end 143 of the pipe 14 is located within the cavity of the outlet pipe 112. Due to the limitation of the diameter of the outlet pipe 112, the rotatable angle of the outlet end 143 is small. The first limiting part 119 further limits the first connecting part 141, and the second limiting part 118 limits the inlet end 142, thereby restricting the multi-directional rotation of the pipe 14. Specifically, when the outlet end 143 of the pipe 14 rotates about an axis parallel to the length direction of the first manifold 1, the first connecting portion 141 also rotates about another axis parallel to the length direction of the first manifold 1. Due to the action of the first limiting portion 119, the pipe 14 is limited. When the outlet end 143 of the pipe 14 rotates about an axis parallel to the thickness direction of the first manifold 1, the first connecting portion 141 also rotates about another axis parallel to the thickness direction of the first manifold 1. The inlet end 142 swings in a plane perpendicular to the thickness direction of the first manifold 1. Due to the limitation of the outlet pipe 112 and the limitation of the second limiting portion 118, the pipe 14 is limited. When the outlet end 143 of the piping 14 rotates about an axis parallel to the width direction of the first manifold 1, the first connecting portion 141 also rotates about another axis parallel to the width direction of the first manifold 1. The inlet end 142 moves closer to or further away from the bottom wall of the second groove portion 114. Due to the restriction of the second groove portion 114 and the restriction of the first limiting portion 119, the piping 14 is limited. In summary, regardless of the rotation and displacement of the outlet end 143 in any direction, the piping 14 can be limited by the action of the first limiting portion 119, the second limiting portion 118, the outlet pipe 112, the protrusion 145, and the second groove portion 114, thereby improving the reliability of the installation and limiting of the piping 14.

[0067] In practical applications, the first side 40 is farther from the ground than the second side 50. It can be understood that the first manifold 1 is arranged inclined or perpendicular to the ground. Due to gravity and the flow of the heat exchange medium, air accumulates in the area of ​​the second cavity 20 near the first side 40. This application provides a piping 14, with its inlet end 142 located in the second cavity 20 and close to the first side 40, and its outlet end 143 at least partially located within the cavity of the outlet pipe 112. Air enters the piping 14 from the inlet end 142, flows along the inner cavity of the piping 14, and exits into the outlet pipe 112 from the outlet end 143. The air flows out of the heat exchanger along with the heat exchange medium, and the piping 14 guides the air to the outlet pipe 112, where it is discharged from the heat exchanger along with the heat exchange medium. Compared to existing technologies, this application includes a manifold assembly comprising a piping 14 and a first manifold 1. It eliminates the opening on the first manifold 1 for mounting the exhaust pipe, simplifying its structure. It also eliminates the pipe connected to the exhaust pipe, reducing leakage points and lowering the manufacturing cost of the heat exchange system. When air is exhausted, the piping 14 functions as an exhaust pipe. After the air is exhausted, the heat exchange medium flows through the piping 14, preventing heat exchange medium diversion and minimizing its impact on the heat exchanger's performance.

[0068] In some other embodiments, the heat exchanger is a single-pass heat exchanger. Specifically, the first manifold 1 has only a first chamber, and the second manifold 2 has only a second chamber. The heat exchange core 3 includes a plurality of third heat exchange tubes arranged along the length direction of the first manifold 1. The thickness direction of the third heat exchange tubes is parallel to or coincides with the length direction of the first manifold 1, and the inner cavity of each third heat exchange tube connects the first chamber and the second chamber. The first manifold 1 includes an inlet pipe 111, and the second manifold 2 includes an outlet pipe 112. The cavity of the inlet pipe 111 communicates with the first chamber, and the cavity of the outlet pipe 112 communicates with the second chamber. Piping 14 cooperates with the second manifold 2 and is located within the second manifold 2. When the heat exchanger is in operation, the heat exchange medium enters the first chamber through the inlet pipe 111. The heat exchange medium in the first chamber is then distributed to several third heat exchange tubes. The heat exchange medium flows along the lumens of these third heat exchange tubes and then converges into the second chamber. Finally, the heat exchange medium flows out of the heat exchanger through the outlet pipe 112. While flowing through the third heat exchange tubes, the heat exchange medium inside the heat exchanger exchanges heat with the heat exchange medium outside the heat exchanger.

[0069] In some other embodiments, the heat exchanger is a multi-pass heat exchanger. Specifically, the first manifold 1 includes several chambers that are not interconnected within the first manifold 1, and the second manifold 2 includes several chambers that are not interconnected within the second manifold 2. The heat exchange core 3 includes several heat exchange tubes, which are divided into multiple sections. Each section of the heat exchange tubes connects to one chamber of the first manifold 1 and one chamber of the second manifold 2, thereby forming a multi-pass heat exchanger. The piping 14 is located in a chamber that communicates with the outlet pipe 112. Depending on the design of the heat exchanger, this chamber can be located in either the first manifold 1 or the second manifold 2. The first sealing element 13 includes several seventh segments with the same design principle as the first segment 137. The seventh segments are located between two adjacent chambers of the first manifold 1 and also between two adjacent chambers of the second manifold 2.
