DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0021] In addition, unless contradictory, the embodiments and features in the embodiments in the present application can be combined with each other. Hereinafter, the present application will be described in detail in conjunction with the embodiments with reference to the drawings.

[0022] As shown in Figs. 1 to 11, a first embodiment of the present application provides a collecting tube including a housing 10 having a plurality of collecting channels 11, the plurality of collecting channels 11 being spaced apart. Here, the housing 10 is further provided with a plurality of connecting portions 12 spaced apart. The plurality of connecting portions 12 are provided in one-to-one correspondence with the plurality of collecting channels 11, each connecting portion 12 is connected to the corresponding collecting channel 11, and the connecting portion 12 is used to connect to a heat exchange flat tube. Specifically, the "plurality" in this embodiment includes two or more. The collecting tube in this embodiment is not only applicable to a flat plate heat exchanger, but also to a V-shaped heat exchanger.

[0023] When the collecting tube provided by this embodiment is used, a plurality of collecting channels 11 are provided in the housing 10, and each collecting channel 11 is provided with a corresponding connecting part 12, so that the collecting channels 11 can communicate with the corresponding collecting channels 11 through the connecting parts 12. During installation, a two-flow path or multi-flow path can be realized by simply providing one collecting channel 11 on each end of the heat exchange tube assembly, thereby reducing the number of collecting tubes required for the heat exchanger, simplifying the installation procedure, and making the installation easier. Therefore, the collecting tube provided by this embodiment can solve the technical problem of the complicated installation of a two-flow path or multi-flow path heat exchanger in the prior art.

[0024] Specifically, in this embodiment, each connection portion 12 includes a plurality of connection ports 121, which are spaced apart along the extension direction of the housing 10 so as to facilitate connection to a plurality of heat exchange tubes therethrough.

[0025] In this embodiment, the multiple connection ports 121 of one connection part 12 and the multiple connection ports 121 of the other connection part 12 are staggered along the extending direction of the housing 10. By adopting such a structural installation, the multiple heat exchange tubes are staggered to prevent them from interfering with each other, which is advantageous in terms of structural layout.

[0026] Specifically, the housing 10 in this embodiment includes a first plate 13 and a second plate 14, and the first plate 13 is provided with a plurality of opening grooves, which are spaced apart from one another. The plurality of connection parts 12 are all provided on the second plate 14, which is provided on the first plate 13 and located at the openings of the plurality of opening grooves, such that the first plate 13 and the second plate 14 are surrounded to form a plurality of collecting channels 11. Adopting such a structural installation makes the structure simple and easy to manufacture.

[0027] In this embodiment, the second plate 14 is a flat plate structure, which can easily connect with the heat exchange tube, avoid the interference of the second plate 14 with the heat exchange tube, and optimize the layout of the structure.

[0028] Specifically, the first plate 13 in this embodiment includes a plurality of arc-shaped plates, which are connected together. By adopting this structure, a plurality of arc-shaped opening grooves can be easily formed by the plurality of arc-shaped plates, so that the collecting channel 11 is surrounded. Specifically, when the heat exchanger is a two-passage heat exchanger, the first plate 13 includes two arc-shaped plates, that is, the number of the arc-shaped plates is equal to the number of the passages of the heat exchanger. Specifically, when it is a two-passage heat exchanger, the collecting tube can have a B-type structure, and one end of the heat exchange tube can be provided with a collecting tube, and the other end of the heat exchange tube can be provided with a normal collecting tube structure.

[0029] Preferably, housing 10 in this embodiment is of one-piece construction, thus facilitating manufacture.

[0030] In this embodiment, the connection port 121 has a rod-shaped structure, and the extension direction of the connection port 121 is perpendicular to the extension direction of the housing 10. By adopting such a structure, the heat exchange tube and the flow collector tube can be easily connected, and the communication area of ​​the connection part between the flow collector tube and the heat exchange tube is ensured, while at the same time, the height of the connection port 121 is made as low as possible, making it easy to increase the number of connection ports 121 in the housing 10, and ensuring that the housing 10 can be connected to a plurality of heat exchange tubes.

[0031] Another embodiment of the present application provides a heat exchanger including a heat exchange tube assembly and a collector tube, the collector tube being the above provided collector tube connected to the heat exchange tube assembly.

[0032] Specifically, the heat exchange tube assembly in this embodiment includes a first heat exchange flat tube 20, which includes a first communication segment 21, a main body segment 22, and a second communication segment 23, which are connected in sequence, the first communication segment 21 is provided at a first end of the main body segment 22 and located in the middle of the first end, the second communication segment 23 is provided at a second end of the main body segment 22 and located in the middle of the second end, and the first communication segment 21 and the second communication segment 23 are both used to communicate with the collection channel 11 of the collection tube. By adopting the structure of the first heat exchange flat tube 20 in this embodiment, the layout and the throttling structure of the first communication segment 21 and the second communication segment 23 can be optimized to avoid the first communication segment 21 and the second communication segment 23 from interfering with other structures of the heat exchanger.

[0033] In this embodiment, the collecting tube is provided with a first collecting channel, a second collecting channel, and a third collecting channel, and the first collecting channel is provided between the second collecting channel and the third collecting channel. The heat exchange tube assembly further includes a second heat exchange flat tube 30 and a third heat exchange flat tube 40, and the first heat exchange flat tube 20 communicates with the first collecting channel, the second heat exchange flat tube 30 communicates with the second collecting channel, and the third heat exchange flat tube 40 communicates with the third collecting channel. Specifically, the multiple connection ports 121 of one connecting portion 12 and the multiple connection ports 121 of the other connecting portion 12 are offset from each other, so that the first heat exchange flat tube 20, the second heat exchange flat tube 30, and the third heat exchange flat tube 40 are spaced apart along the extension direction of the housing 10. Specifically, in this embodiment, the first heat exchange flat tube 20 is located between the second heat exchange flat tube 30 and the third heat exchange flat tube 40, which is advantageous for optimizing the layout of the spatial structure. The second heat exchange flat tube 30 and the third heat exchange flat tube 40 in this embodiment have the same structure, and both use an eccentrically drawn structure so as to easily optimize the layout of the structure.

[0034] Specifically, in this embodiment, the first heat exchange flat tube 20, the second heat exchange flat tube 30 and the third heat exchange flat tube 40 form a heat exchange flat tube group, and the first heat exchange flat tube 20 corresponds to the first connection port 121, the second connection port 121 and the third connection port 121, and the first connection port 121, the second connection port 121 and the third connection port 121 are arranged at intervals in a stepped manner.

[0035] Specifically, in this embodiment, the second heat exchange flat tube 30 is provided at both ends with a first eccentric throttle structure and a second eccentric throttle structure, both of which are used to connect to the flow collecting tube. Here, the first eccentric throttle structure and the second eccentric throttle structure are both biased to one side of the second heat exchange flat tube 30, and the second heat exchange flat tube 30 using such a structure is called the second heat exchange flat tube 30 eccentric to the same side. Alternatively, the first eccentric throttle structure is biased to one side of the second heat exchange flat tube 30, and the second eccentric throttle structure is biased to the other side of the heat exchange flat tube, and the second heat exchange flat tube 30 using such a structure is called the second heat exchange flat tube 30 eccentric to the opposite side.

[0036] Specifically, when the heat exchanger in this embodiment has a two-flow path structure, the flow direction of the two-flow path structure differs depending on the structure of the second heat exchange flat tubes 30 used. When the second heat exchange flat tubes 30 eccentric to the same side are used, the liquid flows in from the same side and flows out from the same side, and when the second heat exchange flat tubes 30 eccentric to the opposite side are used, the liquid flows in from one side and flows out from the other side.

[0037] When the heat exchanger in this embodiment has a three-flow path structure, the flow directions of the different circuits of the three-flow path structure differ depending on the structure of the second heat exchange flat tube 30 used. Specifically, the structures of the second heat exchange flat tube 30 and the third heat exchange flat tube 40 are the same, and when the second heat exchange flat tube 30 eccentric to the same side is used, the liquid in the second heat exchange flat tube 30 and the third heat exchange flat tube 40 flows in from the same side and flows out from the same side, and when the second heat exchange flat tube 30 eccentric to the opposite side is used, the liquid in the second heat exchange flat tube 30 and the third heat exchange flat tube 40 flows in from one side and flows out from the other side.
