[0027] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0028] Please refer to Figure 1 and Figure 2 , the heat exchanger 1000 includes a first header 10 and a first positioning member 20. The two first headers 10 are spaced apart from each other. The first positioning member 20 is disposed between the two first headers 10. One side of the first positioning member 20 is connected to one first header 10, and the other side of the first positioning member 20 is connected to the other first header 10. The first positioning member 20 is used to position the two first headers 10.

[0029] The heat exchanger 1000 further includes a second header 30, a second positioning member 40, and flat tubes 50. The two second headers 30 are spaced apart from each other. The second headers 30 are interconnected with the first headers 10 through the flat tubes 50. The second positioning member 40 is disposed between the two second headers 30. One side of the second positioning member 40 is connected to one second header 30, and the other side of the second positioning member 40 is connected to the other second header 30. The second positioning member 40 is used to position the two second headers 30. The following is a specific description of the first header 10, the first positioning member 20, the second header 30, the second positioning member 40, and the flat tubes 50.

[0030] For the above-mentioned first header 10 and first positioning member 20, as Figure 2 and Figure 3As shown, the two first manifolds 10 are spaced apart, and the first positioning member 20 is disposed between the two first manifolds 10. One side of the first positioning member 20 is connected to one first manifold 10, and the other side of the first positioning member 20 is connected to the other first manifold 10. The first positioning member 20 can position the two first manifolds 10. Compared with the related art, in which the manual alignment method is used, the traditional manual alignment method requires multiple adjustments and calibrations, with complex operations and time-consuming processes. In this application, the first positioning member 20 is used to position the two first manifolds 10, which can simplify the installation steps and improve the assembly efficiency. The first positioning member 20 can provide stable support and fixation for the two first manifolds 10, ensuring that the relative positions of the first manifolds 10 remain unchanged during operation, thereby enhancing the overall structural stability of the heat exchanger. It can be understood that the connection method between the first positioning member 20 and the first manifold 10 includes, but is not limited to, clamping, welding, screwing, etc.

[0031] In some embodiments, the two first manifolds 10 are not interconnected with each other, and the interiors of the first positioning member 20 and the first manifolds 10 are not interconnected with each other. The non-interconnection of the two first manifolds 10 means that they can respectively carry different fluids or fluids in different states (such as different phases of the refrigerant), thus realizing more flexible fluid distribution and control. At the same time, the non-interconnection between the interior of the first positioning member 20 and the first manifolds 10 ensures the independence of the fluid in the first manifolds 10, avoiding the mixing of fluids between the first positioning member 20 and the first manifolds 10. The independent fluid channels and non-interconnected design reduce the risk of fluid leakage.

[0032] In some embodiments, the two first manifolds 10 are interconnected with each other, and the interiors of the first positioning member 20 and the first manifolds 10 are interconnected with each other. Through the connectivity between the first positioning member 20 and the interiors of the first manifolds 10, the fluid can flow more smoothly between the heat exchanger components, reducing the flow resistance, thereby improving the heat exchange efficiency. The connectivity between the first positioning member 20 and the first manifolds 10 not only helps with fluid distribution but also enhances the structural stability of the heat exchanger. Such a setting can reduce the structural deformation caused by uneven fluid pressure.

[0033] In some embodiments, the first positioning member 20 includes a plurality of adjacent first arc portions 201 and second arc portions 202. The plurality of first arc portions 201 are arranged in parallel and at intervals, and the plurality of second arc portions 202 are arranged in parallel and at intervals. The first arc portion 201 is provided with a first arc groove 201a, and the second arc portion 202 is provided with a second arc groove 202a. The lower surface of one of the first header pipes 10 abuts at least partially against the bottom of the first arc groove 201a, and the upper surface of the other first header pipe 10 abuts at least partially against the bottom of the second arc groove 202a. The first arc groove 201a and the second arc groove 202a can precisely support the upper and lower surfaces of the two first header pipes 10 respectively, ensuring a stable positional relationship between the two first header pipes 10 during the assembly process. Through the tight fit between the arc grooves and the first header pipes 10, the vibration and displacement of the first header pipes 10 during operation can be effectively reduced, thereby enhancing the overall structural stability of the heat exchanger.

[0034] In some embodiments, a plurality of first arc grooves 201a combine to form a first positioning groove (not labeled), and the first positioning groove is used to position one of the first header pipes 10. A plurality of second arc grooves 202a combine to form a second positioning groove (not labeled), and the second positioning groove is used to position the other first header pipe 10.

[0035] In some embodiments, the opening of the first arc groove 201a faces upward, the opening of the second arc groove 202a faces downward, and the first arc portion 201 and the second arc portion 202 are bent away from each other.

[0036] In some embodiments, please refer to Figure 4 together. A liquid inlet 101 is further provided on the side wall of the first header pipe 10. The liquid inlet 101 communicates with the inside of the first header pipe 10, and the liquid inlet 101 is used for allowing an external fluid to enter the first header pipe 10.

[0037] In some embodiments, a first mounting hole 102 is provided on the side wall of the first header pipe 10 opposite to the second header pipe 30. The first mounting hole 102 is used to mount one end of the flat tube 50, and the first mounting hole 102 communicates with the inside of the flat tube 50.

[0038] For the above-mentioned second header pipe 30, second positioning member 40, and flat tube 50, as Figure 2As shown, two second header pipes 30 are arranged at intervals. The second header pipes 30 are interconnected with the first header pipe 10. One end of the flat pipe 50 is connected to the first header pipe 10, and the other end of the flat pipe 50 is connected to the second header pipe 30. The flat pipe 50 is communicated with the first header pipe 10 and the second header pipe 30. The second positioning member 40 is arranged between the two second header pipes 30. One side of the second positioning member 40 is connected to one second header pipe 30, and the other side of the second positioning member 40 is connected to the other second header pipe 30. The second positioning member 40 can position the two second header pipes 30. Compared with the related art, in the traditional manual alignment method, multiple adjustments and calibrations are required, and the operation is complex and time-consuming. In this application, the second positioning member 40 is used to position the two second header pipes 30, which can simplify the installation steps and improve the assembly efficiency. The second positioning member 40 can provide stable support and fixation for the two second header pipes 30, ensuring that the relative positions of the second header pipes 30 remain unchanged during operation, thereby enhancing the overall structural stability of the heat exchanger. It can be understood that the connection method between the second positioning member 40 and the second header pipe 30 includes but is not limited to clamping, welding, screwing, etc.

[0039] In some embodiments, the two second header pipes 30 are not interconnected with each other, and the interiors of the second positioning member 40 and the second header pipes 30 are not interconnected with each other. The non-interconnection of the two second header pipes 30 means that they can respectively carry different fluids or fluids in different states, so as to achieve more flexible fluid distribution. At the same time, the non-interconnection of the interior of the second positioning member 40 and the second header pipes 30 ensures the independence of the fluid in the second header pipes 30 and avoids the mixing of fluids between the second positioning member 40 and the second header pipes 30. The independent fluid channels and non-interconnected design reduce the risk of fluid leakage.

[0040] In some embodiments, please refer to Figure 5 and Figure 6 , the two second header pipes 30 are interconnected with each other, and the interiors of the second positioning member 40 and the second header pipes 30 are interconnected with each other. Through the interconnected design between the two second header pipes 30, the fluid can be distributed between the two second header pipes 30 to avoid uneven local flow rate, thereby improving the heat exchange efficiency. The connectivity between the second positioning member 40 and the second header pipes 30 not only helps with fluid distribution but also enhances the structural stability of the heat exchanger. Such a setting can reduce the structural deformation caused by uneven fluid pressure.

[0041] In some embodiments, the second positioning member 40 includes a plurality of adjacent third arc portions 401 and fourth arc portions 402. The plurality of third arc portions 401 are arranged in parallel and at intervals, and the plurality of fourth arc portions 402 are arranged in parallel and at intervals. The third arc portion 401 is provided with a third arc groove 401a, and the fourth arc portion 402 is provided with a fourth arc groove 402a. The lower surface of one of the second header pipes 30 abuts at least partially against the bottom of the third arc groove 401a, and the upper surface of the other second header pipe 30 abuts at least partially against the bottom of the fourth arc groove 402a. Among them, the third arc groove 401a and the fourth arc groove 402a can precisely support the upper and lower surfaces of the two second header pipes 30 respectively, ensuring a stable positional relationship between the two second header pipes 30 during the assembly process. Through the close fit between the arc grooves and the second header pipes 30, the vibration and displacement of the second header pipes 30 during operation can be effectively reduced, thereby enhancing the overall structural stability of the heat exchanger.

[0042] In some embodiments, a plurality of third arc grooves 401a are combined to form a third positioning groove (not labeled), and the third positioning groove is used to position one of the second header pipes 30. A plurality of fourth arc grooves 402a are combined to form a fourth positioning groove (not labeled), and the fourth positioning groove is used to position the other second header pipe 30.

[0043] In some embodiments, the notch of the third arc groove 401a faces upward, the notch of the fourth arc groove 402a faces downward, and the third arc portion 401 and the fourth arc portion 402 are bent away from each other.

[0044] In some embodiments, a first liquid flow hole 301 is provided on one of the second header pipes 30, and a second liquid flow hole 302 is provided on the other second header pipe 30. The second liquid flow hole 302 communicates with the third arc groove 401a. A connecting column 4011 extends from the third arc portion 401 in the direction of one of the second header pipes 30. A connecting through hole 4011a penetrating the third arc portion 401 is provided on the connecting column 4011, and the connecting through hole 4011a communicates with the third arc groove 401a. The connecting column 4011 is inserted into the first liquid flow hole 301, and the first liquid flow hole 301, the connecting through hole 4011a, and the second liquid flow hole 302 communicate with each other. Through the communication of the first liquid flow hole 301, the connecting through hole 4011a, and the second liquid flow hole 302, the fluid can be distributed and flow between the two second header pipes 30. Among them, the design of the connecting column 4011 not only realizes the connection of the fluid between the two second header pipes 30, but also enhances the structural stability of the heat exchanger. Such a setting can reduce the vibration and deformation caused by uneven fluid pressure, and at the same time make the overall design more compact.

[0045] It should be noted that: To achieve the mutual connection between the two first manifolds 10, the connection manner between the two first manifolds 10 can refer to the connection manner for the connection between the two second manifolds 30 described above, and details will not be repeated here.

The second mounting hole 303 is disposed opposite to the first mounting hole 102, and the second mounting hole 303 is in communication with the interior of the flat tube 50. It can be understood that: The fluid can flow from the first mounting hole 102 through the flat tube 50 in the direction of the second mounting hole 303, or alternatively, the fluid can flow from the second mounting hole 303 through the flat tube 50 in the direction of the first mounting hole 102.
