[0050] Example implementations will now be described more fully with reference to the accompanying drawings. Example implementations may, however, be implemented in many different forms and should not be construed as limited to the implementations set forth herein; rather, these implementations are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the example implementations to those skilled in the art. Like reference numerals refer to like elements throughout the figures, and description of the same elements will be omitted from some descriptions to avoid repetition.

[0051] In the following description of various example embodiments of the present application, reference is made to the accompanying drawings, which form a part hereof, and in which are shown by way of illustration various example structures, systems, and steps in which aspects of the present application can be practiced. It is to be understood that other specific arrangements of parts, structures, example devices, systems, and steps can be utilized and structural and functional modifications can be made without departing from the scope of the present application. Also, while the terms "over," "under," "between," and the like, can be used in this disclosure to describe relationships between various elements, these terms are used liberally to describe all spatial relationships between elements, for example, as oriented in the examples shown in the figures. No mere spatial or temporal limitations are intended or should be inferred; thus, for example, a device described as over another can physically be disposed under the referenced device, and the like.

[0052] It is to be understood that the terms "including", "comprising", "consisting" and "having" and variations thereof when used in this specification and in the following claims, shall be interpreted not to surround exclusivity, that is, these terms are to be interpreted in an inclusive sense. For example, a process, method, system, product or apparatus that comprises a list of steps or elements is not limited to only those steps or elements but can include other steps or elements not expressly listed or inherent to such process, method, system, product or apparatus.

[0053] Relative terms such as "lower" or "bottom" and "upper" or "top" can be used herein to describe one element's relationship to another element as illustrated in the Figures. It will be understood that relative terms are intended to include different orientations of the device in addition to the orientation depicted in the Figures. For example, if the device in one of the figures is turned over, elements described as being on the "lower" side of other elements would then be oriented on "upper" sides of the other elements. The exemplary term "lower" can therefore encompass both an orientation of "lower" and "upper," depending on the particular orientation of the figure. Similarly, if the device in one of the figures is turned over, elements described as "below" or "beneath" other elements would then be oriented "above" the other elements. The exemplary terms "below" or "beneath" can, therefore, encompass both an orientation of "below" and "above," depending on the particular orientation of the figure.

[0054] Referring to Figures 1 to 3 and Figure 14 , a flow path module 1 includes a flow path body 10 and a connector 20. The flow path body 10 is formed by a stack of multiple layers of sheet material, the flow path body 10 including a flow passage 101 and a transition interface 102 in communication with the flow passage 101, the sheet material including a first sheet 11 and a second sheet 12, the first sheet 11 and the second sheet 12 being located at outermost sides of the flow path body 10, the transition interface 102 being formed on the first sheet 11 and the second sheet 12, an end of the connector 20 being connected to the transition interface 102.

The connector 20 includes a first tube 201, a second tube 202, a third tube 203, and a fourth tube 204.

[0055] Figures 4 to 5 Another flow path module 1 is shown, including a flow path body 10 and a connector 20. The flow path body 10 is formed by a stack of multiple layers of sheet material, the flow path body 10 including a flow passage 101 and a transition interface 102 in communication with the flow passage 101, the sheet material including a first sheet 11 and a second sheet 12, the first sheet 11 and the second sheet 12 being located at outermost sides of the flow path body 10, the transition interface 102 being formed on the first sheet 11 and the second sheet 12, an end of the connector 20 being connected to the transition interface 102. At least one third sheet 13 is provided between the first sheet 11 and the second sheet 12, the flow passage 101 being mainly formed by the third sheet 13, the first sheet 11 and the second sheet 12 enclosing the flow passage 101, the transition interfaces 102 on the first sheet 11 and the second sheet 12 being in communication with the flow passage 101. The connector 20 includes a first tube 201, a second tube 202, a third tube 203, and a fourth tube 204.

[0056] Figures 1 to 3 the flow path module 1 of Figures 4 to 5The difference between the flow path module 1 and the one below lies in the specific relative position of the connector 20. See [link / reference]. Figure 2 The first pipe 201 connects to the first plate 11; as shown in the diagram from left to right, the second pipe 202, the third pipe 203, and the fourth pipe 204 connect to the second plate 12. (See diagram) Figure 5 The first pipe 201 connects to the first plate 11; according to the diagram from left to right, the fourth pipe 204, the third pipe 203, and the second pipe 202 connect to the second plate 12. Because the flow path main body 10 of the above two flow path modules 1 has a symmetrical structure, during the assembly of the flow path main body 10 and the connecting pipe 20, a situation will arise where… Figures 1 to 3 The flow path module 1 is assembled into Figures 4 to 5 The flow path module 1. Connector 20 is used to connect to various phases 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. Since the first pipe 201, second pipe 202, third pipe 203, and fourth pipe 204 each correspond to different external devices, an incorrectly assembled flow path module 1 cannot be used and will be scrapped.

[0057] Figure 6 and Figure 7 This illustration shows a first embodiment of the flow path module 1 of this application, wherein the flow path module 1 includes a flow path body 10 and a connecting pipe 20. The flow path body 10 is formed by stacking multiple layers of plates. The flow path body 10 includes a flow cavity 101 and a transition interface 102 communicating with the flow cavity 101. The plates include a first plate 11 and a second plate 12, which are respectively located on the outermost sides of the flow path body 10. The transition interface 102 is formed on the first plate 11 and the second plate 12, and the end of the connecting pipe 20 is connected to the transition interface 102. At least one third plate 13 is disposed between the first plate 11 and the second plate 12. The connecting pipe 20 includes a first tube 201, a second tube 202, a third tube 203, and a fourth tube 204. Both the first plate 11 and the second plate 12 are provided with a foolproof structure 40, which are correspondingly disposed to avoid assembly errors of the first plate 11 and the second plate 12. The corresponding disposal means that the front and rear positions are corresponding in the plate stacking direction.

[0058] The flow path module 1 of this application has a foolproof structure 40 on the first plate 11 and the second plate 12 on the outermost side of the flow path body 10, which can effectively avoid assembly errors of the first plate 11 and the second plate 12.

[0059] In this embodiment, the first pipe 201 is connected to the first plate 11; the second pipe 202, the third pipe 203, and the fourth pipe 204 are connected to the second plate 12, and the positions of the second pipe 202, the third pipe 203, and the fourth pipe 204 relative to the first pipe 201 are... Figures 1 to 3 The flow path module 1 shown is the same. After setting the foolproof structure 40, the flow path body 10 and the connecting pipe 20 will not be misaligned during assembly.Figures 6 to 7 The flow path module 1 shown is assembled such that the positions of the second tube 202, the third tube 203 and the fourth tube 204 relative to the first tube 201 are the same as those shown in Fig. 1. Figures 4 to 5 The flow path module 1 shown is the same as that shown in Fig. 1, that is, the relative positions of the first plate and the second plate are not reversed, thereby improving the convenience of assembly of the flow path module 1, ensuring the correctness of assembly of the flow path module 1, and avoiding the scrapping of the flow path module 1.

[0060] In the present embodiment, the third plate 13 is also provided with the fool-proof structure 40, and the fool-proof structures 40 of the first plate 11, the second plate 12 and the third plate 13 are correspondingly provided to avoid the assembly error of the third plate 13 with the first plate 11 and the second plate 12. In the present embodiment, the number of the third plate 13 is 3, and in some other embodiments, the number of the third plate 13 can be other numbers, which can be selected according to actual needs.

[0061] In the present embodiment, the plate material includes two mutually parallel surfaces and a side surface 14 connecting the two surfaces, the side surface 14 includes a plurality of corners, and the fool-proof structure 40 is arranged on any one corner. The fool-proof structure 40 includes a chamfer, and the structure or size of the chamfer is different from that of the corner. The chamfer is arranged on one of the corners of the plate material, and the chamfer can be obviously distinguished from other corners, which destroys the symmetry of the flow path body 10, so that whether the assembly error occurs can be obviously observed during assembly, thereby ensuring the correctness of assembly and improving the assembly efficiency.

[0062] In the present embodiment, the length of the right angle side of the chamfer is greater than the length of the right angle side of the chamfer of the remaining corners which are not provided with the fool-proof structure 40. In actual processing, the chamfer of the corner of the plate material usually belongs to a process chamfer, which is not obvious when observed by the naked eye. The fool-proof structure 40 of the present application specially processes a larger chamfer at one of the corners, and the length of the right angle side of the chamfer is greater than the length of the right angle side of the similar process chamfer of the remaining corners, for example, the length of the right angle side of the chamfer of the fool-proof structure 40 can be selected to be 2 times, 3 times, 5 times, etc. of the length of the right angle side of the similar process chamfer of the remaining corners.

[0063] In the present embodiment, the adapter 102 is a plurality of, and one connecting pipe 20 is correspondingly welded in each adapter 102. The plurality of adapters 102 can make the flow path module 1 applicable to the flow of multiple fluids.

[0064] The outermost surface of the first plate 11 is connected to the first pipe 201 through the adapter 102, and the outermost surface of the second plate 12 is connected to the second pipe 202, the third pipe 203 and the fourth pipe 204 through multiple adapters 102. In other embodiments, the outermost surface of the first plate 11 can be connected to multiple pipes 20 through multiple adapters 102, and the outermost surface of the second plate 12 can be connected to one pipe 20 through one adapter 102. The outermost surface of the first plate 11 can also be connected to multiple pipes 20 through multiple adapters 102, and the outermost surface of the second plate 12 can be connected to multiple pipes 20 through multiple adapters 102. The number and distribution of the pipes 20 and the adapters 102 can be adjusted as needed.

[0065] In this application, the four corners of the multi-layer plate are provided with locking structures 100, such as bolts, screws and the like. The locking structure 100 can provide a pre-tightening force to press the multi-layer plate together before welding, thereby improving the welding efficiency.

[0066] The flow path module 1 of the present application is applied to an air conditioning system, for example, installed in the outdoor unit of the air conditioning system. The housing of the outdoor unit usually has a compressor, a tank, an outdoor heat exchanger, an oil separator, various valves and other components that constitute the refrigerant circuit, as well as electrical installation units, etc. The flow path module 1 of the present application is usually installed in the indoor unit in a horizontal state of the multi-layer plate, and has a flat overall structure, which can optimize the pipe structure in the indoor unit, improve the pipe integration, reduce the pipe space occupation, and reduce the overall volume of the outdoor unit.

[0067] In this embodiment, the number of pipes of the present application is four, and the air conditioning system includes a stop valve, a tank and a compressor, one pipe is connected to the compressor, one pipe is connected to the stop valve, and the remaining two pipes are connected to the tank. The flow path module of the present application is connected to the air conditioning system, which can make the layout of the connecting pipes in the air conditioning system more reasonable, and can configure connecting pipes with shorter length, thereby simplifying the pipe structure of the entire air conditioning system and improving the efficiency of refrigerant distribution.

[0068] In this embodiment, the flow path body 10 further comprises a soldering sheet 30, which is arranged between two adjacent plates and avoids the flow-through cavity 101. The arrangement of the soldering sheet 30 allows the soldering sheet 30 to melt and the soldering material to be evenly distributed on the entire surface of the plate, so that the connection between the adjacent plates is more firm and the sealing performance is good. After the soldering sheet 30 melts, the soldering material can flow along the plate, further improving the firm sealing performance between the two adjacent plates. The soldering sheet 30 is arranged between the first plate 11 and the third plate 13, between the second plate 12 and the third plate 13, and between multiple third plates 13.

[0069] The flow path module 1 of the present application also has a second embodiment, which is different from the first embodiment in thatFigures 6 to 7 The flow path module 1 of the second embodiment has substantially the same structure as the flow path module 1 of the first embodiment in the basic configuration. Therefore, in the following description of the flow path module 1 of the second embodiment, the structures already described in the first embodiment are not repeated. Figures 6 to 7 The structures already described in the first embodiment are not repeated in the following description of the flow path module 1 of the second embodiment. In addition, the same reference numerals are assigned to the structures that are the same as the structures of the flow path module 1 described in the first embodiment. Therefore, in the following description of the second embodiment, mainly the differences from the flow path module 1 of the first embodiment are described. In the flow path module 1 of the second embodiment, see Figures 6 to 7 , the flow path module 1 differs from the flow path module 1 of the first embodiment in that the fool-proof structure 40 is different. Figures 6 to 7 In the first embodiment, the fool-proof structure 40 is a chamfer on one of the bent corners of the plate. In the second embodiment, see Figures 8 to 9 , the fool-proof structure 40 includes a rounded corner. The structure or size of the rounded corner is different from the bent corner, and in this embodiment, the radius of the rounded corner is larger than the radius of the rounded corner of the remaining bent corners on which the fool-proof structure 40 is not provided. Figures 6 to 7 Figures 8 to 9 In actual processing, the arc of the bent corner of the plate is usually a process arc and is not obvious to the naked eye. In the present application, a large-radius rounded corner is specially processed on one of the bent corners of the plate, and the radius of the rounded corner is larger than the radius of the similar process arc of the remaining bent corners. For example, the radius of the rounded corner of the fool-proof structure 40 can be selected to be 2 times, 3 times, 5 times, or the like of the radius of the similar process arc of the remaining bent corners.

[0070] The flow path module 1 of the present application also has a third embodiment. The flow path module 1 of the third embodiment has substantially the same structure as the flow path module 1 of the first embodiment in the basic configuration. Therefore, in the following description of the flow path module 1 of the third embodiment, the structures already described in the first embodiment are not repeated. The structures already described in the first embodiment are not repeated in the following description of the flow path module 1 of the third embodiment. In addition, the same reference numerals are assigned to the structures that are the same as the structures of the flow path module 1 described in the first embodiment. Therefore, in the following description of the third embodiment, mainly the differences from the flow path module 1 of the first embodiment are described. In the flow path module 1 of the third embodiment, see

[0071] , the flow path module 1 differs from the flow path module 1 of the first embodiment in that the fool-proof structure 40 is different. Figures 6 to 7 In the first embodiment, the fool-proof structure 40 is a chamfer on one of the bent corners of the plate. In the third embodiment, see Figures 6 to 7 , the plate includes two surfaces parallel to each other and a side surface 14 connecting the two surfaces, and the fool-proof structure 40 is provided on the side surface 14 of the plate. Figures 6 to 7 Figures 6 to 7 In actual processing, the arc of the bent corner of the plate is usually a process arc and is not obvious to the naked eye. In the present application, a large-radius rounded corner is specially processed on one of the bent corners of the plate, and the radius of the rounded corner is larger than the radius of the similar process arc of the remaining bent corners. For example, the radius of the rounded corner of the fool-proof structure 40 can be selected to be 2 times, 3 times, 5 times, or the like of the radius of the similar process arc of the remaining bent corners. Figures 6 to 7 Figures 10 to 11 The flow path module 1 of the present application also has a third embodiment. The flow path module 1 of the third embodiment has substantially the same structure as the flow path module 1 of the first embodiment in the basic configuration. Therefore, in the following description of the flow path module 1 of the third embodiment, the structures already described in the first embodiment are not repeated.

[0072] ​​In the third embodiment, the fool-proof structure 40 includes a notch. The notch can be semicircular in shape. The notch can also be V-shaped, U-shaped, or polygonal in shape. The notch is provided on the side surface 14 of the plate member, which destroys the symmetry of the plate member, thereby providing a correct positional relationship of the plate members of the fluid module 1 during assembly, and ensuring that the fluid module is assembled correctly.

[0073] There is also a fourth embodiment of the fluid path module 1 of the present application, which has substantially the same structure as the fluid path module 1 of the embodiment of Figures 6 to 7 . Therefore, in the following description of the fourth embodiment of the fluid path module 1, the structures that have been described in the description of the embodiment of Figures 6 to 7 will not be repeated. In addition, the same reference numerals are used to denote the same structures of the fluid path module 1 described in the description of the embodiment of Figures 6 to 7 . Therefore, in the following description of the present embodiment, the differences between the fluid path module 1 of the present embodiment and the fluid path module 1 of the embodiment of Figures 6 to 7 will mainly be described. In the fourth embodiment, the fool-proof structure 40 is different from the fool-proof structure 40 of the embodiment of Figures 6 to 7 , Figures 6 to 7 which is provided on the chamfer of one of the corners of the plate member. In the fourth embodiment of the fluid path module 1, the fool-proof structure 40 includes a locking position offset structure that moves the position of one of the locking structures 100 of the plurality of plate members, and the locking structure 100 includes a locking hole provided on each plate member, and the locking position offset structure moves the position of the locking hole on each plate member.

[0074] There is also a fifth embodiment of the fluid path module 1 of the present application, which has substantially the same structure as the fluid path module 1 of the embodiment of Figures 6 to 7 . Therefore, in the following description of the fifth embodiment of the fluid path module 1, the structures that have been described in the description of the embodiment of Figures 6 to 7 will not be repeated. In addition, the same reference numerals are used to denote the same structures of the fluid path module 1 described in the description of the embodiment of Figures 6 to 7 . Therefore, in the following description of the present embodiment, the differences between the fluid path module 1 of the present embodiment and the fluid path module 1 of the embodiment of Figures 1 to 3 will mainly be described. In the fifth embodiment of the fluid path module 1, the fool-proof structure 40 is provided on the surface of the plate member, and the fool-proof structure 40 includes a character mark, an alphabetical mark, or a graphic mark.

The fool-proof structure 40 is arranged on the surface of the first plate 11 and the second plate 12, where the text mark, the letter mark or the graphic mark is arranged. The fool-proof structure 40 can be arranged on the surface of the third plate 13, or not.

[0076] In the above embodiments, for example, the positional relationship between the first pipe 201, the second pipe 202, the third pipe 203 and the fourth pipe 204 is described by taking the positional relationship shown in the figure as an example. Actually, the positional relationship between the first pipe 201, the second pipe 202, the third pipe 203 and the fourth pipe 204 in the above embodiments can also be the positional relationship shown in the figure. It can also be other types of positional relationship. The specific type can be selected according to actual needs. Once selected, the fool-proof structure 40 of the present application can avoid errors during assembly of the fluid module 1, and avoid that the assembled fluid module 1 is not the selected type of positional relationship.
