[0049] Furthermore, in the following detailed description, numerous specific details are set forth for ease of explanation to provide a thorough understanding of the embodiments disclosed herein. However, it will be apparent that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and apparatuses are illustrated to simplify the figures.

[0050] See Figures 1 to 13 According to an exemplary embodiment of the present invention, a heat exchanger 1000 includes a manifold assembly 100 and heat exchange tubes 200a and 200b. For example... Figures 1 to 3 As shown, in the heat exchanger 1000 of an exemplary embodiment of the present invention, the manifold assembly 100 is connected to the ends of the heat exchange tubes 200a and 200b and is in fluid communication with the heat exchange tubes 200a and 200b. The heat exchanger 1000 may also include fins 300 disposed between adjacent heat exchange tubes 200a and 200b. In the exemplary embodiment shown, the fins 300 are corrugated fins. In other embodiments not shown, the fins may be insert-type fins, with the heat exchange tubes inserted into the fin holes or fin slots of the fins. Furthermore, as... Figures 1 to 3As shown, according to an exemplary embodiment of the present invention, the heat exchanger 1000 is a dual-loop heat exchanger including a first heat exchanger 200a and a second heat exchanger 200b, wherein the first heat exchanger 200a and the second heat exchanger 200b are arranged alternately, and one end of the first heat exchanger 200a and one end of the second heat exchanger 200b are both connected to a manifold assembly 100, while the other end of the first heat exchanger 200a and the other end of the second heat exchanger 200b are both connected to another manifold assembly 100. More specifically, one end of each first heat exchanger tube 200a is connected to a flow divider 120 (described in detail below) in the manifold assembly 100 and is in fluid communication with a first chamber 111 (described in detail below) in the manifold assembly 100; while one end of each second heat exchanger tube 200b is connected to a flow divider 120 in the manifold assembly 100 and is in fluid communication with a second chamber 112 (described in detail below) in the manifold assembly 100. Furthermore, one manifold assembly 100 has a flow path inlet 1 for the first heat exchanger 200a and a flow path outlet 2 for the second heat exchanger 200b at one end along its axial direction, and the other manifold assembly 100 has a flow path outlet 3 for the first heat exchanger 200a and a flow path inlet 4 for the second heat exchanger 200b at one end along its axial direction. One manifold assembly 100 has end caps 5 and 7 at both ends along its axial direction, and the other manifold assembly 100 has end caps 6 and 8 at both ends along its axial direction.

[0051] See Figures 1 to 13 According to an exemplary embodiment of the present invention, the manifold assembly 100 includes a split tube 110 and a split plate 120.

[0052] Specifically, according to exemplary embodiments of the present invention, see, for example, [reference needed]. Figures 3 to 9 The sub-lumen tube 110 defines a first chamber 111 and a second chamber 112 independent of the first chamber 111, and the first chamber 111 and the second chamber 112 are arranged along the axial direction of the sub-lumen tube 110. According to an exemplary embodiment of the present invention, the sub-lumen tube 110 may be integrally formed, for example, the sub-lumen tube 110 may be formed from the same material by an extrusion process. Of course, in other embodiments, the sub-lumen tube 110 may also be assembled from multiple components.

[0053] Specifically, according to exemplary embodiments of the present invention, see, for example, [reference needed]. Figure 3 , Figures 10 to 13 The flow divider 120 is connected to the branch pipe 110 and fluidly isolates the first chamber 111 and the second chamber 112 from each other. For example, at least a portion of the outer wall surface 121 of the flow divider 120 may co-form the outer peripheral wall surface of the collector assembly 100 with at least a portion of the outer peripheral wall surface of the branch pipe 110. More specifically, according to an exemplary embodiment of the invention, see, for example, [reference needed]. Figures 10 to 11The manifold 120 includes an outer wall surface 121, an inner wall surface 122 opposite to the outer wall surface 121, and a plurality of heat exchange tube receiving portions 123a and 123b penetrating the outer wall surface 121 and the inner wall surface 122. The heat exchange tube receiving portion 123a is used to receive and hold one end of a first heat exchange tube 200a, and the heat exchange tube receiving portion 123b is used to receive and hold one end of a second heat exchange tube 200b. The manifold 120 also includes a protrusion 124 that protrudes from the inner wall surface 122 to define a first flow channel 125 on one side and a second flow channel 126 on the other side. The first flow channel 125 is independent of the second flow channel 126; that is, the two flow channels are independent of each other and do not communicate with each other. The manifold 120 may be formed of the same material as the manifold tube 110, and the protrusion 124 may be formed by performing a stamping process on the manifold 120. Furthermore, the outer wall surface 121 and / or inner wall surface 122 of the manifold 120 may be coated with a solder layer to facilitate the connection and bonding of the manifold 120 with the manifold tube 110. Because the manifold 120 is coated with a solder layer, the manifold tube 110 can adopt a structure without a composite layer, reducing the difficulty of welding and thus saving costs.

[0054] More specifically, according to an exemplary embodiment of the present invention, see, for example, [reference needed]. Figures 4 to 6 and Figures 10 to 11 In the manifold 120, the protrusion 124 defines a first surface 1240; simultaneously, the manifold 110 also includes a partition wall 115, which defines a second surface 1150. The first surface 1240 of the protrusion 124 and the second surface 1150 of the partition wall 115 are fluid-tightly connected together, thereby fluidly isolating the first flow channel 125 and the second flow channel 126 from each other. For example, if the outer wall surface 121 and / or the inner wall surface 122 of the manifold 120 are coated with a solder layer, the first surface 1240 of the protrusion 124 and the second surface 1150 of the partition wall 115 can be fluid-tightly connected together by a brazing process. The fluid-tight connection between the first surface 1240 of the protrusion 124 and the second surface 1150 of the partition wall 115 ensures fluid isolation between the first flow channel 125 and the second flow channel 126.

[0055] Specifically, according to the present invention, see Figures 4 to 6 and Figures 7 to 9 A first passage 113, 113' is defined between the partition wall 115 and the first chamber 111; a second passage 114, 114' is defined between the partition wall 115 and the second chamber 112. For example, in Figures 4 to 6In one exemplary embodiment shown, the first channel may be a first through opening 113 formed between one edge of the partition wall 115 and one inner peripheral wall surface of the partition tube 110; the second channel may be a second through opening 114 formed between the other edge of the partition wall 115 and the other inner peripheral wall surface of the partition tube 110. For example, in... Figures 7 to 9 In another exemplary embodiment shown, the first channel may be a plurality of first through holes 113' formed in the partition wall 115; the second channel may be a plurality of second through holes 114' formed in the partition wall 115. The first and second through holes may have cross-sections of any suitable shape, such as rectangular, circular, elliptical, or semi-circular. According to the present invention, a through-hole form or a plurality of through holes may be used depending on the actual situation to adapt to different fluid flow requirements.

[0056] According to the inventive concept of the present invention, in the manifold assembly 100, after the manifold plate 120 and the manifold tube 110 are assembled and connected together, the first flow channel 125 is in fluid communication with the first chamber 111 only via the first channels 113, 113', while the second flow channel 126 is in fluid communication with the second chamber 112 only via the second channels 114, 114'. Thus, two independent flow channels / chambers are defined in the manifold assembly 100. Furthermore, to facilitate the assembly between the manifold plate 120 and the manifold tube 110, the manifold tube 110 may have a guide portion 116, and the side portion of the manifold plate 120 may be fluid-tightly connected to the guide portion 116. Compared to the prior art heat exchanger structure using four manifolds, two of which require pre-bending, the manifold assembly 100 provided by the present invention simplifies the structure of the heat exchanger, thereby reducing installation space and cost.

[0057] Specifically, according to exemplary embodiments of the present invention, see, for example, [reference needed]. Figures 10 to 13 The protrusion 124 of the flow divider 120 has a wavy cross-section. Specifically, in cross-section, the protrusion 124 includes a crest 1241, a trough 1242, and a connecting portion 1243 connecting the crest 1241 and the trough 1242. Meanwhile, the plurality of heat exchange tube housings include a first set of heat exchange tube housings 123a and a second set of heat exchange tube housings 123b, wherein the first set of heat exchange tube housings 123a is located within a first flow channel 125, and the second set of heat exchange tube housings 123b is located within a second flow channel 126. One end of each first heat exchange tube 200a can be connected to the first heat exchange tube housing 123a of the flow divider 120; one end of each second heat exchange tube 200b can be connected to the second heat exchange tube housing 123b of the flow divider 120. The wave-shaped design, including crests and troughs, not only enhances the structural strength of the manifold 120 but also optimizes the fluid flow path and improves heat exchange efficiency.

[0058] According to exemplary embodiments of the present invention, see, for example, [examples omitted]. Figures 10 to 13 Multiple heat exchanger tube housings 123a and 123b are arranged along the length of the flow divider 120. The heat exchanger tube housings 123a and 123b are respectively disposed between two adjacent connecting portions 1243. The heat exchanger tube housing 123a located on the first side of each connecting portion 1243 along the length of the flow divider 120 belongs to the first group of heat exchanger tube housings 123a, and the heat exchanger tube housing 123b located on the second side of each connecting portion 1243 along the length of the flow divider 120 opposite to the first side belongs to the second group of heat exchanger tube housings 123b. One of the crest portion 1241 and the trough portion 1242 is located on one side of the protrusion 124, and the other of the crest portion 1241 and the trough portion 1242 is located on the other side of the protrusion 124.

[0059] According to the present invention, the number of heat exchange tube receiving portions 123a located on the first side of each connection portion 1243 along the length direction of the flow divider 120 and the number of heat exchange tube receiving portions 123b located on the second side of each connection portion 1243 along the length direction of the flow divider 120 opposite to the first side can be arranged in equal proportions or in different proportions. For example, in Figures 10 to 11 In one exemplary embodiment shown, the number of heat exchange tube accommodating portions 123a and the number of heat exchange tube accommodating portions 123b in the flow divider 120 are arranged in a 1:1 ratio. For example, in... Figures 12 to 13 In another exemplary embodiment shown, the number of heat exchange tube accommodating portions 123a and the number of heat exchange tube accommodating portions 123b in the flow divider 120' are arranged in a 1:2 ratio. Thus, by adjusting the ratio of the number of heat exchange tubes in different flow paths, the needs of different application scenarios can be met.

[0060] The operation mode of the manifold assembly for a heat exchanger and the heat exchanger having the aforementioned manifold assembly according to an embodiment of the present invention is as follows.

[0061] like Figures 1 to 13As shown, the first refrigerant enters the first chamber 111 of a manifold assembly 100 from the flow path inlet 1 for the first heat exchanger 200a, and then enters the first flow channel 125 from the first chamber 111 via the first channels 113, 113'. From the first flow channel 125, it enters the first heat exchanger 200a from one end via the first set of heat exchange tube receiving portions 123a formed in the flow divider 120. The first refrigerant undergoes heat exchange in the first heat exchanger 200a by the fins 300. Subsequently, the first refrigerant flows from the other end of the first heat exchanger 200a into the first flow channel 125 of another manifold assembly 100, and then flows out from the first flow channel 125 of the manifold assembly 100 via the first channels 113, 113' and the first chamber 111 from the flow path outlet 4 for the first heat exchanger 200a. Similarly, the second refrigerant enters the second chamber 112 of a manifold assembly 100 from the flow path inlet 3 for the second heat exchanger 200b, and then enters the second flow channel 126 from the second chamber 112 via the second channels 114, 114'. From the second flow channel 126, it enters the second heat exchanger 200b from one end via the second set of heat exchange tube housings 123b formed in the splitter plate 120. The second refrigerant is heat-exchanged by fins 300 in the second heat exchanger 200b. Subsequently, the second refrigerant flows from the other end of the second heat exchanger 200b into the second flow channel 126 of another manifold assembly 100, and then flows out from the second flow channel 126 of the manifold assembly 100 via the second channels 114, 114' and the second chamber 112 from the flow path outlet 2 for the second heat exchanger 200b. It should be noted that, according to the dual-loop heat exchanger provided by the present invention, the flow of the first refrigerant and the second refrigerant can coexist in both loops, or the flow of the first refrigerant or the second refrigerant can coexist in only one loop.

[0062] The manifold assembly for a heat exchanger and the heat exchanger having the aforementioned manifold assembly, as described in the embodiments of the present invention, have, for example, a more compact structure, better fluid isolation, and improved heat exchange efficiency.

[0063] Furthermore, the manifold assembly for a heat exchanger and the heat exchanger having the aforementioned manifold assembly, as described in the embodiments of the present invention, can, for example, simplify the structure of a dual-loop heat exchanger.

[0064] Those skilled in the art will understand that the embodiments described above are exemplary, and that modifications can be made to them without departing from the general concept and spirit of the invention. The structures described in the various embodiments can be freely combined without structural or principle-related conflicts. The scope of the invention is defined by the claims and their equivalents.
