Description

Technical Field

[0001] This application relates to the field of refrigeration technology, and in particular to a flow path module and its manufacturing method. Background Technology

[0002] Air conditioning systems typically use flow path modules for refrigerant distribution. These modules mainly consist of a fluid inlet connector, a flow path body, and a fluid outlet connector. Both the inlet and outlet connectors must connect to external connectors, allowing a portion of the fluid from the external connectors to flow through the flow path body from the inlet connector to the outlet connector, and then be distributed to another portion of the external connectors. The connections between the inlet connector, flow path body, outlet connector, and external connectors are usually made by welding.

[0003] The existing flow path modules have complex structures, and the fluid flow chambers inside the flow path modules are irregularly shaped or contain multiple flow chambers. The flow velocity of the refrigerant in the flow path module is affected, resulting in untimely refrigerant distribution and poor fluid stability, which is not conducive to the operation of the air conditioning system. Summary of the Invention

[0062] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, they are provided so that the invention will be thorough and complete, and the concept of the exemplary embodiments will be fully conveyed to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0063] In the following description of various exemplary embodiments of the invention, reference is made to the accompanying drawings, which form part of the invention, and which illustrate by way of example different exemplary structures, systems, and steps that can implement various aspects of the invention. It should be understood that other specific embodiments of the components, structures, exemplary devices, systems, and steps may be used, and structural and functional modifications may be made without departing from the scope of the invention. Furthermore, while the terms “above,” “between,” “within,” etc., may be used in this specification to describe various exemplary features and elements of the invention, these terms are used herein for convenience only, such as the orientation according to the examples shown in the drawings. Nothing in this specification should be construed as requiring a specific three-dimensional orientation of the structure to fall within the scope of the invention.

[0064] It is understood that the terms "comprising" and "having," and any variations thereof, in the embodiments of this invention are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or components inherent to such processes, methods, products, or devices.

[0065] Relative terms such as “down” or “bottom” and “up” or “top” may be used herein to describe the relationship of one element to another, as illustrated in the figures. It should be understood that relative terms are intended to include different orientations of the device beyond those shown in the figures. For example, if a device in one of the figures is flipped, an element described as “down” or “bottom” of another element will be oriented “up” or “top” of that element. Thus, the exemplary term “down” can include both “down” and “up” orientations, and the term “bottom” can include both “bottom” and “top” orientations, depending on the specific orientation of the figure. Similarly, if a device in one of the figures is flipped, an element described as “down” or “bottom” of another element will be oriented “up” or “top” of that element. Thus, the exemplary term “bottom” or “below” can include both “up” and “down” orientations.

[0067] See Figures 1 to 6 This application provides a flow path module 1, including a flow path body 10 and a connecting pipe 20. The flow path body 10 includes a first plate 11, a second plate 12, and an annular member 15 disposed between the first plate 11 and the second plate 12. The annular member 15 has openings at both ends, with one end connected to the first plate 11 and the other end connected to the second plate 12. The first plate 11, the second plate 12, and the annular member 15 form a flow cavity 101. An adapter 102 is provided on the flow path body 10, and the adapter 102 communicates with the flow cavity 101. The connecting pipe 20 is connected to the flow path body 10 through the adapter 102.

[0068] In the flow path module 1 of this application, an annular member 15 is provided between the first plate 11 and the second plate 12. The two ends of the annular member 15 are respectively connected to the first plate 11 and the second plate 12 to form a flow cavity 101. The structure is simple and easy to process and manufacture. The flow cavity 101 is defined by the annular member 15 and the two plates. The flow path module 1 only provides one flow cavity 101. The flow cavity 101 has a simple shape and a large size, which is beneficial to improving the fluid stability when the fluid passes through the flow cavity 101. Compared with multiple flow cavities 101 and flow cavities 101 with complex shapes, the flow cavity 101 of the flow path module 1 of this application has a high efficiency in distributing fluid, and the fluid is more uniform, resulting in a better cooling effect.

[0069] In this embodiment, the shapes of the first plate 11 and the second plate 12 are adapted to the external shape of the annular member 15. The annular member 15 has a hollow interior forming a flow cavity 101. The first plate 11 and the second plate 12 cover the upper and lower ends of the annular member 15, sealing the flow cavity 101. The length and width dimensions of the first plate 11 and the second plate 12 are approximately the same; the thickness dimensions of the first plate 11 and the second plate 12 can be the same, different, or significantly different. In this embodiment, the first plate 11 has four connecting pipes 20, and the second plate 12 has one connecting pipe 20. In other embodiments, the number of connecting pipes 20 can be four, with three connecting pipes 20 on the first plate 11 and one connecting pipe 20 on the second plate 12. Of course, the number of connecting pipes 20 can be adjusted according to actual needs.

[0070] Multiple connecting pipes 20 are used to connect to various components in the compressor, storage tank, outdoor heat exchanger, oil separator, various valves (four-way valve, electronic expansion valve, shut-off valve, etc.), and other piping in the refrigerant flow path. The flow path body 10 consists of a first plate 11, a second plate 12, and an annular component 15. The first plate 11 and the second plate 12 are located on the outermost side of the flow path body 10 and are provided with multiple adapters 102. The multiple connecting pipes 20 are respectively connected to the first plate 11 and the second plate 12 through the multiple adapters 102. The shape of the flow cavity 101 can be adjusted according to actual needs. Fluid can flow in from at least one of the multiple connecting pipes 20, pass through the flow cavity 101 of the flow path body 10, and then flow out from the remaining connecting pipes 20.

[0071] The flow path module 1 of this application is used in air conditioning systems, for example, installed inside the outdoor unit of an air conditioning system. The outdoor unit typically houses components forming the refrigerant circuit, such as a compressor, storage tank, outdoor heat exchanger, oil separator, and various valves, as well as electrical installation units. The flow path module 1 of this application is typically installed horizontally on the outdoor unit with the first plate 11 and the second plate 12, exhibiting a flat overall structure. This optimizes the piping structure within the outdoor unit, improves piping integration, reduces piping space requirements, and decreases the overall size of the outdoor unit.

[0072] In other embodiments, the number of pipes is four. The air conditioning system includes a shut-off valve, a storage tank, and a compressor. One pipe connects to the compressor, one pipe connects to the shut-off valve, and the remaining two pipes connect to the storage tank. The flow path module of this application is connected to the air conditioning system, which allows for a more rational layout of the connecting pipes in the air conditioning system. Shorter connecting pipes can be configured, so that the connecting pipes of the entire air conditioning system will not cross, thereby improving the efficiency of refrigerant distribution.

[0073] See Figure 3 and Figure 4 In this embodiment, the first plate 11 has multiple adapter ports 102, and the second plate 12 has one adapter port 102. In other embodiments, the second plate 12 may also have multiple adapter ports 102. The number of adapter ports 102 can be adjusted according to the number of connecting pipes 20. Both the first plate 11 and the second plate 12 are approximately rectangular, with rounded corners at the four corners. There are multiple adapter ports 102, and each adapter port 102 corresponds to a connecting pipe 20 welded to it. The size of the adapter port 102 can be adjusted according to the size of the connecting pipe 20. In this embodiment, the first plate 11 and the second plate 12 are provided with adapter ports 102, while the annular component 15 is not provided with adapter ports 102.

[0074] In this embodiment, the annular component 15 is formed by bending a plate and welding the ends together. The plate can be laser-cut or punched. The annular component 15 is formed by bending and welding a plate, which simplifies the manufacturing process and improves the sealing performance of the flow cavity 101. Laser cutting or punching offers high precision and good surface quality.

[0075] The first plate 11 and the second plate 12 can also be processed by laser cutting or punching, which can make the surfaces of the first plate 11 and the second plate 12 smooth and have high dimensional accuracy, so that the overall appearance of the flow path module 1 is more beautiful.

[0076] In this embodiment, see Figure 5 and Figure 6 The annular member 15 has a butt joint 151 along its circumference, and the width W of the butt joint 151 is ≤0.2mm. For example, 0.05mm, 0.2mm, 0.15mm, etc. In some other embodiments, the annular member 15 may also have two or more butt joints 151. The width W of each butt joint 151 is ≤0.2mm, which allows the butt joints 151 to be welded firmly and sealed, thereby ensuring good sealing performance of the flow cavity 101 formed by the annular member 15.

[0077] In this embodiment, the annular component 15 has a rectangular orthographic projection onto a plane perpendicular to its own axis, with two opposing first sides 152 and two opposing second sides 153, connected by a transition fillet. The length of the first side 152 is greater than the length of the second side 153, and a butt joint 151 is located on the second side 153. The butt joint 151 can be located on either of the second sides 153, or on both. The butt joint 151 is typically located approximately at the midpoint of the second side 153, but it can also be located at other positions on the second side 153. In other embodiments, the length of the first side 152 can be equal to the length of the second side 153, making the annular component 15 resemble a square ring. Correspondingly, the shapes of the first plate 11 and the second plate 12 are typically also designed as squares. Because the butt joint 151 is located on the shorter side of the rectangle, the heat-affected zone during welding is smaller, and the annular component 15 is less prone to thermal deformation.

[0078] like Figures 5 to 7 As shown, in this embodiment, the annular component 15 has a first surface 154 facing the first plate 11 and a second surface 155 facing the second plate 12. The distance between the first surface 154 and the second surface 155 is the height H of the annular component 15, where 1mm ≤ H ≤ 30mm. For example, 2mm, 5mm, 10mm, 15mm, 20mm, 24mm, 28mm, etc. The distance between the inner and outer surfaces of the annular component 15 is the wall thickness T of the annular component 15, where 0.5mm ≤ T ≤ 20mm. For example, 1mm, 2mm, 5mm, 8mm, 10mm, 12mm, 15mm, 18mm, etc. In this embodiment, the flow path module 1 is formed by furnace brazing, laser welding, or argon arc welding.

[0079] The flow path module 1 of this application also has a second embodiment, in which the flow path module 1 of the second embodiment is related to... Figures 1 to 7 Compared to the flow path module 1 of the second embodiment, it has a substantially the same structure in its basic construction. Therefore, in the following description of the flow path module 1 of this second embodiment, it will not be described again. Figures 1 to 7 The structure has already been described in the implementation method. Additionally, regarding... Figures 1 to 7 The structures described in the embodiments are identical to those of the flow path module 1, and are labeled with the same reference numerals. Therefore, in the following description of this embodiment, the structures are mainly those of the same type. Figures 1 to 7 The differences between the flow path module 1 in the second embodiment and the previous embodiment will be explained. For the flow path module 1 in this second embodiment, see [link to relevant documentation]. Figure 8The annular component 15 has two opposing first sides 152 and two opposing second sides 153, wherein the length of the first side 152 is greater than the length of the second side 153. The butt joint 151 is located on the first side 152, that is, on the side with the longer length. The butt joint 151 can be located on either of the first sides 152, or on both of the first sides 152. The position of the butt joint 151 is usually set at approximately the midpoint of the first side 152, but it can also be set at other positions on the first side 152.

[0080] In fact, the butt joint 151 of the annular component 15 can also be set at the first side 152 and the second side 153 respectively. The position of the butt joint 151 is usually set at approximately the midpoint between the first side 152 and the second side 153, but it can also be set at other positions.

Therefore, in the following description of this embodiment, the structures are mainly those of the same type. Figures 1 to 7 The differences between the flow path module 1 in this third embodiment and the previous one will be explained. In this third embodiment, the annular member 15 has a circular orthographic projection on a plane perpendicular to its own axis. In this embodiment, the annular member 15 is a ring, and the mating seam 151 of the annular member 15 can be located at any position on the ring. Correspondingly, the shapes of the first plate 11 and the second plate 12 are also designed to be circular, that is, the first plate 11 and the second plate 12 are circular plates, but this is not a limitation, and they can also be other shapes, as long as they can close the flow cavity 101 formed by the annulus.

[0082] The flow path module 1 of this application also has a fourth embodiment, in which the flow path module 1 of the fourth embodiment is related to... Figures 1 to 7 Compared to the flow path module 1 of the previous embodiment, it has a substantially similar structure in its basic construction.

For the flow path module 1 in this fourth embodiment, see [link to relevant documentation]. Figures 9 to 12 The annular part 15 is a rectangular tube integrally formed. 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 main body of the flow path 10, while the cavity in the middle of the rectangular tube forms the flow cavity 101.

[0083] In this embodiment, see Figures 11 to 12 An adapter 102 is also provided on the annular component 15, and the adapter 102 connects to the connecting pipe 20. Multiple adapters 102 can be provided, and they can be respectively provided on different surfaces of the annular component 15. The height H of the annular component 15 must be greater than the maximum size of the adapter 102 provided on the annular component 15. The rectangular tube is formed by laser cutting or punching.

[0084] The flow path module 1 of this application also has a fifth embodiment, which is related to the flow path module 1 of the fifth embodiment. Figures 1 to 7 Compared to the flow path module 1 of the previous embodiment, it has a substantially similar structure in its basic construction. Therefore, in the following description of the flow path module 1 of this fifth embodiment, it will not be described again. Figures 1 to 7 The structure has already been described in the implementation method. Additionally, regarding... Figures 1 to 7 The structures described in the embodiments are identical to those of the flow path module 1, and are labeled with the same reference numerals. Therefore, in the following description of this embodiment, the structures are mainly those of the same type.

See also: Figures 9 to 12 , Figures 9 to 12 In one embodiment, the annular component 15 is a rectangular tube; in this fifth embodiment, the annular component 15 is a circular tube, integrally formed. The upper and lower ends of the circular tube are welded to the first plate 11 and the second plate 12 respectively to form the flow path body 10. The cavity in the middle of the circular tube forms the flow cavity 101. The shapes of the first plate 11 and the second plate 12 can be adaptively adjusted to be circular. The circular tube is formed using laser cutting or punching processes.

[0085] In this embodiment, an adapter 102 is also provided on the annular component 15, and the adapter 102 connects to the connecting pipe 20. The height H of the annular component 15 must be greater than the maximum size of the adapter 102 provided on the annular component 15. There can be multiple adapters 102, which can be respectively provided at different positions on the annular component 15.

[0086] Based on the fourth and fifth embodiments described above, the annular component 15 can also be designed as an irregularly shaped tube, such as a D-shape or other irregularly shaped tube with a cavity. It can be integrally formed by casting. In this case, the corresponding first plate 11 and second plate 12 are also irregularly shaped.

[0087] The flow path module 1 of this application also has a sixth embodiment, in which the flow path module 1 of the sixth embodiment is related to... Figures 1 to 7Compared to the flow path module 1 of the previous embodiment, it has a substantially similar structure in its basic construction. Therefore, in the following description of the flow path module 1 of this sixth embodiment, it will not be described again. Figures 1 to 7 The structure has already been described in the implementation method. Additionally, regarding... Figures 1 to 7 The structures described in the embodiments are identical to those of the flow path module 1, and are labeled with the same reference numerals. Therefore, in the following description of this embodiment, the structures are mainly those of the same type. Figures 1 to 7 The differences between the flow path module 1 in the implementation of this sixth embodiment will be explained. For the flow path module 1 in this sixth embodiment, see [link to relevant documentation]. Figures 13 to 14 The annular component 15 is welded from four plates. 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 main body of the flow path 10. The central cavity after the four plates are spliced ​​and welded forms the flow cavity 101. The four plates are connected by laser welding, argon arc welding or furnace brazing to form the annular component 15.

[0088] In this embodiment, see Figures 13 to 14 An adapter 102 is also provided on the annular component 15, and the adapter 102 connects to the connecting pipe 20. There can be multiple adapters 102, which can be respectively provided on different surfaces of the annular component 15. The height H of the annular component 15 must be greater than the maximum size of the adapter 102 provided on the annular component 15.

[0089] The annular component 15 can be made by welding three plates or five plates. Alternatively, it can be made by welding multiple plates depending on the actual requirements.

[0090] The foregoing is a detailed description of several exemplary embodiments of the flow path module 1 proposed in this application. Additionally, see [link to relevant documentation]. Figures 1 to 8 This application also provides a method for manufacturing a flow path module 1, comprising: Step S1: welding a first plate 11 and a corresponding connecting pipe 20 to form a first assembly; welding a second plate 12 and a corresponding connecting pipe 20 to form a second assembly. Step S2: welding the first assembly to an opening at one end of an annular member 15; welding the second assembly to an opening at the other end of the annular member 15 to form the flow path module 1. The annular member 15 is formed by laser cutting or punching followed by bending and has at least one butt joint 151. Before step S2, the butt joint 151 of the annular member 15 is welded first.

[0091] The manufacturing method of the flow path module 1 proposed in this application involves welding the connecting pipe 20 first, and then welding the flow path body 10, which simplifies the welding operation and improves the welding sealing performance of the flow path body 10.

[0092] In this embodiment, step S2 includes: pressing the first component, the second component, and the annular component 15 together, and then performing laser welding or argon arc welding. Pressing allows for more accurate positioning of the first component, the second component, and the annular component 15, ensuring that misalignment does not occur during welding, and guaranteeing the overall connection accuracy after welding, thereby improving the quality of the entire flow path module 1 and increasing the product qualification rate.

[0093] In this embodiment, the gap between the first component, the second component, and the annular component 15 after being press-fitted together is less than or equal to 0.2 mm. This smaller gap further ensures the positioning accuracy between the first component, the second component, and the annular component 15.

[0094] The above manufacturing method is the subject of this application. Figures 1 to 8 The first manufacturing method of the flow path module 1 of this application Figures 1 to 8 There is also a second type of manufacturing method for the flow path module 1. 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.

[0095] The number of spot welds must be at least two, and the spot welding methods include 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.

[0096] 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.

[0097] See Figures 9 to 12This application also provides a method for manufacturing a flow path module 1, comprising: Step S1: welding a first plate 11 and a corresponding connecting pipe 20 to form a first assembly; welding a second plate 12 and a corresponding connecting pipe 20 to form a second assembly. Step S2: welding the first assembly to one end opening of an 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 an integrally formed rectangular tube, it can also be a circular tube. Step S1 further includes: welding the annular member 15 to the corresponding connecting pipe 20.

[0098] The manufacturing method of the flow path module 1 proposed in this application involves welding the connecting pipe 20 first, and then welding the flow path body 10. This simplifies the welding operation and improves the sealing performance of the flow path body 10.

[0099] In this embodiment, step S2 includes: pressing the first component, the second component, and the annular component 15 together, and then performing laser welding or argon arc welding. Pressing allows for more accurate positioning of the first component, the second component, and the annular component 15, ensuring that misalignment does not occur during welding, and guaranteeing the overall connection accuracy after welding, thereby improving the quality of the entire flow path module 1 and increasing the product qualification rate.

[0100] In this embodiment, the gap between the first component, the second component, and the annular component 15 after being press-fitted together is less than or equal to 0.2 mm. This smaller gap further ensures the positioning accuracy between the first component, the second component, and the annular component 15. In this embodiment, the annular component 15 press-fitted with the first component and the second component is an annular component 15 that has already been welded with a corresponding connecting pipe 20.

[0101] The above manufacturing method is the subject of this application. Figures 9 to 12 The first manufacturing method of the flow path module 1 of this application Figures 9 to 12 There is a second type of manufacturing method for flow path module 1. 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. In this second manufacturing method, step 2 is different from press-fitting. Instead, the first component, the second component, and the annular part 15 are spot-welded together, followed by laser welding, argon arc welding, or furnace brazing. The number of spot welds is greater than or equal to two, and the spot welding uses cold welding, laser welding, or argon arc welding. See [link to documentation]. Figure 12 When the annular component 15 is spot-welded to the first plate 11 and the second plate 12, the spot welding can be performed in the order of ACBD weld points. In this embodiment, the annular component 15 that is spot-welded to the first component and the second component is an annular component 15 that has already been welded with the corresponding connecting pipe 20.

[0102] In this second manufacturing method, the annular component 15 is spot-welded to the first plate 11 and the second plate 12, which can be done by cold spot welding, laser spot welding, or argon arc spot welding. After spot welding, in-furnace brazing is performed to complete the manufacturing of the flow path module 1.

[0103] In this second manufacturing method, the annular component 15 can also be spot-welded to the first plate 11 and the second plate 12, using cold spot welding, laser spot welding, or argon arc spot welding. After spot welding, continuous welding can be performed at the gaps between the annular component 15 and the first plate 11, and at the gaps between the annular component 15 and the second plate 12 to complete the flow path module 1. Continuous welding can be performed using laser welding or argon arc welding.

[0104] See Figures 13 to 14 This application also provides a method for manufacturing a flow path module 1, comprising: Step S1: welding a first plate 11 and a corresponding connecting pipe 20 to form a first assembly; welding a second plate 12 and a corresponding connecting pipe 20 to form a second assembly. Step S2: welding the first assembly to an opening at one end of an annular member 15; welding the second assembly to an opening at the other end of the annular member 15 to form the flow path module 1. The annular member 15 is formed by welding four plates (at least three plates). Step S1 further includes: welding the annular member 15 to the corresponding connecting pipe 20.

[0105] The manufacturing method of the flow path module 1 proposed in this application involves welding the connecting pipe 20 first, and then welding the flow path body 10, which simplifies the welding operation and improves the welding sealing performance of the flow path body 10.

[0106] In this embodiment, step S2 includes: pressing the first component, the second component, and the annular component 15 together, and then performing laser welding or argon arc welding. Pressing allows for more accurate positioning of the first component, the second component, and the annular component 15, ensuring that misalignment does not occur during welding, and guaranteeing the overall connection accuracy after welding, thereby improving the quality of the entire flow path module 1 and increasing the product qualification rate.

[0107] In this embodiment, the gap between the first component, the second component, and the annular component 15 after being press-fitted together is less than or equal to 0.2 mm. This smaller gap further ensures the positioning accuracy between the first component, the second component, and the annular component 15. In this embodiment, the annular component 15 press-fitted with the first component and the second component is an annular component 15 that has already been welded with a corresponding connecting pipe 20.

[0108] The above manufacturing method is the subject of this application. Figures 13 to 14 The first manufacturing method of the flow path module 1 of this application Figures 13 to 14There is also a second type of manufacturing method for the flow path module 1. This second manufacturing method has roughly the same basic steps as the first manufacturing method described above. Therefore, in the following description of this second manufacturing method, the steps already described in the first manufacturing method will not be repeated. Therefore, the following description mainly focuses on the differences from the first manufacturing method. In this second manufacturing method, the main difference is that in step 2, instead of press fitting, the first component, the second component, and the annular part 15 are spot-welded together, followed by laser welding, argon arc welding, or furnace brazing. In this embodiment, the annular part 15 spot-welded to the first component and the second component is an annular part 15 that has already been welded with the corresponding connecting pipe 20. The number of spot welds is greater than or equal to two, and the spot welding is performed using cold welding, laser welding, or argon arc welding.

[0109] In Figures 13 to 14 In the second manufacturing method of flow path module 1, at least three plates of the annular component 15 are spot-welded and positioned before the first component, the second component, and the annular component 15 are spot-welded. This can be compared to... Figure 12 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.

[0110] Furthermore, the annular component 15 is welded from multiple plates. Regardless of the manufacturing method, the multiple plates must first be welded into the annular component 15. The only difference is that one method involves welding the annular component 15 first, and then assembling it. This assembly can be done by pressing followed by welding, or by spot welding followed by welding. The other method does not explicitly distinguish whether the annular component 15 is welded first, and it is only applicable to welding assembly methods that require spot welding. In this method, the multiple plates of the annular component 15 can be spot welded together first, and then the annular component 15 can be spot welded to the first plate 11 and the second plate 12, before the entire assembly is welded together.

[0111] In this second manufacturing method, the annular component 15 is spot-welded to the first plate 11 and the second plate 12, which can be done by cold spot welding, laser spot welding, or argon arc spot welding. After spot welding, in-furnace brazing is performed to complete the manufacturing of the flow path module 1.

[0112] The above describes the manufacturing method of the flow path module 1 of this application. The following will describe in detail the usage process of the flow path module 1 proposed in this application.

[0113] Users can weld the connector 20 of the flow path module 1 to the external connector 20 of the external device that provides or receives fluid, according to actual needs, thereby connecting the flow path module 1 to the air conditioning system. When the fluid inflow device is started, the fluid can flow from a part of the connector 20 of the flow path module 1 through the adapter 102 into the flow cavity 101 of the flow path module 1, and then through other adapters 102 into other connectors 20, thereby flowing to the device that receives the fluid.

[0114] In summary, the flow path module 1 proposed in this application includes a flow path body 10 and a connecting pipe 20. The flow path body 10 includes a first plate 11, a second plate 12, and an annular member 15 disposed between the first plate 11 and the second plate 12. The annular member 15 has openings at both ends, with one end connected to the first plate 11 and the other end connected to the second plate 12. The first plate 11, the second plate 12, and the annular member 15 form a flow cavity 101. An adapter 102 is provided on the flow path body 10, and the adapter 102 communicates with the flow cavity 101. The connecting pipe 20 is connected to the flow path body 10 through the adapter 102.

[0115] The flow path module 1 of this application has an annular component 15 disposed between the first plate 11 and the second plate 12. The two ends of the annular component 15 are respectively connected to the first plate 11 and the second plate 12 to form a flow cavity 101. The structure is simple and easy to manufacture. The flow path module 1 has only one flow cavity 101, and the flow cavity 101 has a simple shape and a large size, which is beneficial to improving the fluid stability when the fluid passes through the flow cavity 101. Compared with multiple flow cavities 101 and flow cavities 101 with complex shapes, the flow path module 1 of this application has a higher efficiency in distributing fluid and a better cooling effect.

[0116] The flow path module 1 of this application is applied to an air conditioning system, which can improve the cooling efficiency of the air conditioning system and increase the refrigerant utilization rate.

[0117] This application also proposes a method for manufacturing the flow path module 1, comprising: step S1: welding a first plate 11 and a corresponding connecting pipe 20 to form a first assembly; welding a second plate 12 and a corresponding connecting pipe 20 to form a second assembly; step S2: welding the first assembly to an opening at one end of an annular member 15; and welding the second assembly to an opening at the other end of the annular member 15 to form the flow path module 1. The manufacturing method of the flow path module 1 of this application simplifies the welding operation and improves the welding sealing performance of the flow path body 10.
