In the present embodiment, the first plate 11 and the second plate 12 are provided with the adapter interfaces 102, and the annular piece 15 is not provided with the adapter interfaces 102.

[0064] In the present embodiment, the annular piece 15 is formed by bending a plate piece and welding the first end to the tail end. The plate piece can be cut by laser cutting or punched. The annular piece 15 is welded after being bent from a plate piece, and the processing technology is simple, and the sealing performance of the flow passage 101 can be improved. The laser cutting or punching has high precision and good surface quality.

[0065] The first plate 11 and the second plate 12 can also be processed by laser cutting or punching, so that the first plate 11 and the second plate 12 have smooth surfaces and high dimensional accuracy, and the overall appearance of the flow path module 1 is more beautiful.

In the flow path module 1 of the sixth embodiment, see Figures 1 to 7 Figures 13 to 14 The annular member 15 is formed by welding four plates together. The upper and lower ends of the rectangular tube are welded to the first plate 11 and the second plate 12, respectively, to form the flow path main body 10. The middle cavity of the four plates after being welded together forms the flow passage 101.

This second manufacturing method has roughly the same basic steps as the first method described above. Therefore, the steps already described in the first method will not be repeated in the following description of this second manufacturing method. Therefore, the following description mainly focuses on the differences from the first manufacturing method. Specifically, in step 2, this second manufacturing method does not use a press-fit method. Instead, it uses spot welding to connect the first component, the second component, and the annular component 15, followed by laser welding, argon arc welding, or furnace brazing. Spot welding is used to position the first component, the second component, and the annular component 15, ensuring the shape and dimensions of the flow path module 1.

[0085] The number of spot welds must be at least two, and the spot welds must be performed using cold welding, laser welding, or argon arc welding. (See also...) Figure 6 When spot welding the annular part 15 to the first plate 11 and the second plate 12, spot welding can be performed in the order of ACBD weld points.

[0086] In this second manufacturing method, the annular part 15 is spot welded to the first plate 11 and the second plate 12. Laser spot welding or argon arc spot welding can be used. After spot welding, solder paste can be applied to the gap between the annular part 15 and the first plate 11 and the gap between the annular part 15 and the second plate 12. Then, in-furnace brazing is performed to complete the flow path module 1.

[0087] See Figures 9 to 12The application further provides a manufacturing method of the flow path module 1, comprising: step S1: welding the first plate 11 and the corresponding connector 20 to form a first assembly; welding the second plate 12 and the corresponding connector 20 to form a second assembly. Step S2: welding the first assembly to one end opening of the annular member 15; welding the second assembly to the other end opening of the annular member 15 to form the flow path module 1. Wherein, when the annular member 15 is a rectangular tube formed integrally, it can also be a circular tube, and step S1 further comprises: welding and connecting the annular member 15 and the corresponding connector 20.

[0088] The manufacturing method of the flow path module 1 provided by the application can simplify the welding operation and improve the sealing performance of the welding of the flow path main body 10 by welding the connector 20 first and then welding the flow path main body 10.

[0089] In the embodiment, step S2 comprises: after the first assembly, the second assembly and the annular member 15 are pressed together, laser welding or argon arc welding is performed. The pressing can realize more accurate positioning between the first assembly, the second assembly and the annular member 15, ensure that dislocation does not occur during the welding process, and ensure the accuracy of the connection position of the whole after welding, thereby improving the quality of the whole flow path module 1 and improving the product qualification rate.

[0090] In the embodiment, the gap between the first assembly, the second assembly and the annular member 15 after being pressed together is less than or equal to 0.2 mm. The smaller gap can further ensure the positioning accuracy between the first assembly, the second assembly and the annular member 15. In the embodiment, the annular member 15 pressed with the first assembly and the second assembly is an annular member 15 which has been welded with the corresponding connector 20.

[0091] The above manufacturing method is a first manufacturing method of the flow path module 1 of the application Figures 9 to 12 The manufacturing method of the flow path module 1 of the application Figures 9 to 12 The manufacturing method of the flow path module 1 of the application further has a second type, and the second manufacturing method has substantially the same steps in the basic steps compared with the above first manufacturing method. Therefore, in the following description of the second manufacturing method, the steps already described in the first manufacturing method will not be repeated. Therefore, in the following description, mainly the differences from the first manufacturing method will be described. Wherein, in the second manufacturing method, in step 2, the pressing method is not used, but the first assembly, the second assembly and the annular member 15 are spot welded together, and then laser welding, argon arc welding or furnace brazing is performed. Wherein, the number of spot welding points is greater than or equal to 2, and the spot welding adopts cold welding, laser welding or argon arc welding. Referring to Figure 12 , when the annular member 15 is spot welded with the first plate 11 and the second plate 12, the spot welding can be performed in the order of ACBD spot welding points. In the embodiment, the annular member 15 spot welded with the first assembly and the second assembly is an annular member 15 which has been welded with the corresponding connector 20.

[0092] In the second manufacturing method, the annular member 15 is spot-welded with the first plate 11 and the second plate 12, which can be cold-weld spot-welding, laser spot-welding or argon arc spot-welding. After spot-welding, furnace brazing is performed to complete the manufacturing of the flow path module 1.

[0093] In the second manufacturing method, the annular member 15 is spot-welded with the first plate 11 and the second plate 12, which can be cold-weld spot-welding, laser spot-welding or argon arc spot-welding. After spot-welding, continuous welding is performed at the gap between the annular member 15 and the first plate 11 and at the gap between the annular member 15 and the second plate 12 to complete the manufacturing of the flow path module 1. The continuous welding can be laser welding or argon arc welding.

[0094] Referring to Figures 13 to 14 The application further provides a manufacturing method of the flow path module 1, which comprises the following steps: S1. welding the first plate 11 and the corresponding connector 20 to form a first assembly, and welding the second plate 12 and the corresponding connector 20 to form a second assembly; S2. welding the first assembly to one end opening of the annular member 15, and welding the second assembly to the other end opening of the annular member 15 to form the flow path module 1. The annular member 15 is welded by four plates (at least three plates). In step S1, the annular member 15 is further welded and connected with the corresponding connector 20.

[0095] The manufacturing method of the flow path module 1 provided by the application can first weld the connector 20 and then weld the flow path body 10, so that the welding operation is simple and the welding sealing performance of the flow path body 10 is better.

[0096] In the embodiment, step S2 comprises: after the first assembly, the second assembly and the annular member 15 are pressed together, laser welding or argon arc welding is performed. The pressing can realize more accurate positioning between the first assembly, the second assembly and the annular member 15, ensure that no misalignment occurs during the welding process, and guarantee the accuracy of the connection position of the whole after welding, thereby improving the quality of the whole flow path module 1 and improving the product qualification rate.

[0097] In the embodiment, the gap between the first assembly, the second assembly and the annular member 15 after being pressed together is less than or equal to 0.2 mm. The smaller gap can further guarantee the positioning accuracy between the first assembly, the second assembly and the annular member 15. In the embodiment, the annular member 15 pressed with the first assembly and the second assembly is the annular member 15 which has been welded with the corresponding connector 20.

[0098] The above manufacturing method is the first manufacturing method of the flow path module 1 of the application Figures 13 to 14 The manufacturing method of the flow path module 1 provided by the application can first weld the connector 20 and then weld the flow path body 10, so that the welding operation is simple and the welding sealing performance of the flow path body 10 is better.

Therefore, in the following description of the second manufacturing method, the steps already described in the first manufacturing method will not be repeated. Therefore, in the following description, mainly the differences from the first manufacturing method will be described. In the second manufacturing method, mainly in step 2, instead of using the press-fitting method, the first assembly, the second assembly and the annular member 15 are connected by spot welding, and then laser welding, argon arc welding or furnace brazing is performed. In this embodiment, the annular member 15 spot welded with the first assembly and the second assembly is an annular member 15 that has already been welded with the corresponding connecting pipe 20, wherein the number of spot welding points is greater than or equal to 2, and the spot welding uses cold welding, laser welding or argon arc welding.

[0099] In this Figures 13 to 14 In the second manufacturing method of the flow path module 1, at least three plates of the annular member 15 are spot welded before the first assembly, the second assembly and the annular member 15 are spot welded. The spot welding of the plates can be similar to Figure 12 When the annular member 15 is spot welded with the first plate 11 and the second plate 12, the spot welding can be performed in the order of ACBD spot welding points.

[0100] In addition, the annular member 15 is welded from multiple plates, and regardless of the manufacturing method, the multiple plates need to be welded into the annular member 15 first, and the difference is only that one is welded into the annular member 15 first, and then welded and assembled; wherein the welded and assembled can be welded after press-fitting, or welded after spot welding. The other does not explicitly distinguish whether the annular member 15 is welded first, and is only suitable for the welded and assembled method of spot welding, and the multiple plates of the annular member 15 can be spot welded first, and then the annular member 15 and the first plate 11 and the second plate 12 are spot welded, and then the whole is welded.
