Detailed implementation manners

[0055] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be fully conveyed to those skilled in the art.

[0056] It should be understood that the terms used herein are for the purpose of describing particular example embodiments only and are not intended to be limiting. Unless the context clearly dictates otherwise, the singular forms "a", "an", and "the" as used herein may also include the plural forms. The terms "comprising", "including", "containing", and "having" are inclusive and thus specify the presence of the stated features, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not to be construed as necessarily requiring them to be performed in the particular order described or illustrated, unless the order of performance is explicitly stated. It should also be understood that additional or alternative steps may be used.

[0057] Although the terms first, second, third, etc. may be used herein to describe multiple elements, components, regions, layers, and / or sections, these elements, components, regions, layers, and / or sections should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or section from another. Unless the context clearly indicates otherwise, terms such as "first" and "second" and other numerical terms used herein do not imply an order or sequence. Thus, the first element, component, region, layer, or section discussed below may be referred to as the second element, component, region, layer, or section without departing from the teachings of the example embodiments.

[0058] For ease of description, spatial relative relation terms may be used in the text to describe the relationship of one element or feature shown in the figure with respect to another element or feature. These relative relation terms are, for example, "inside", "outside", "inner side", "outer side", "below", "beneath", "above", "over", etc. Such spatial relative relation terms are intended to include different orientations of the device during use or operation in addition to the orientations depicted in the figure. For example, if the device in the figure is flipped, then an element described as "below" or "beneath" other elements or features will subsequently be oriented as "above" or "over" other elements or features. Therefore, the exemplary term "below" can include both upward and downward orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative relation descriptors used in the text are interpreted accordingly.

[0059] As Figures 1 to 10 shown, according to the first aspect of an embodiment of the present invention, a pipeline integration module 100 is provided. As Figures 1 to 6 shown, wherein, Figure 1 a schematic structural diagram (including connecting pipes) of the pipeline integration module 100 according to an embodiment of the present invention is schematically shown. Figure 2 is Figure 1 a partial enlarged view of part A in Figure 3 is Figure 1 a schematic structural diagram of the pipeline integration module 100 shown in Figure 4 is Figure 3 a partial enlarged view of part B in Figure 5 is Figure 1 a schematic structural diagram of the pipeline integration module 100 shown in Figure 6 is Figure 5 a cross-sectional view along the C-C section in . The structures described in these six figures are of the same pipeline integration module 100. Specifically, the pipeline integration module 100 includes a first plate body 10 and a second plate body 20. The second plate body 20 cooperates with the first plate body 10 to form a first cavity and a second cavity that are in communication. The first cavity is used to receive fluid, and the second cavity is used to output fluid. Among them, at least one of the first plate body 10 and the second plate body 20 is provided with a first convex member 60. At least part of the second cavity is formed by the first convex member 60. A swirl suppression portion is provided on the first convex member 60, and the fluid outputs outward after passing through the swirl suppression portion.

[0060] In the pipeline integration module 100 of the present invention, by providing a swirl suppression portion on the first convex member 60, when the fluid outputs outward from the second cavity, the swirl of the fluid can be reduced, the fluid resistance can be lowered, and thus the pressure loss of the pipeline system in the air conditioner outdoor unit 200 can be reduced.

[0061] It should be noted that the first convex member 60 in the prior art is usually circular in structure, and vortices are likely to occur in the first cavity, resulting in an increase in the resistance of the fluid. The vortex suppression part here refers to a component that can suppress vortices. It can improve the circular structure in the prior art. Changing the first convex member 60 to a non-circular structure can achieve the effect of suppressing vortices. For example, the first convex member 60 can be set as an elliptical structure, a rectangular structure, or a trapezoidal structure, etc. When the fluid flows through the vortex suppression part of these structures, the vortices can be reduced.

[0062] In some alternative embodiments, at least one of the second plate body 20 and the first plate body 10 is provided with a groove, and the first plate body 10 and the second plate body 20 are connected in a covering manner. The groove forms part of the first cavity; the first convex member 60 includes a first convex portion 61, and the first convex portion 61 and a groove are provided on the same plate body.

[0063] The covering connection here includes various situations such as welding, screw connection, or flange connection, etc. Usually, the first plate body 10 and the second plate body 20 are directly fixedly connected by a brazing process. The first cavity is defined by the groove. The shape of the first cavity here corresponds to the shape of the groove. For example, if the groove is U-shaped, the shape of the first cavity is square-shaped. If the groove is semi-circular, the shape of the first cavity is D-shaped.

[0064] Through this setting method, first cavities of various shapes can be formed, which is convenient for the fluid to flow inside the first cavity. The shape of the groove can be selected according to needs to make the fluid flow smoothly.

[0065] In some alternative embodiments, the first plate body 10 is provided with a first groove 31, and the second plate body 20 is provided with a second groove 32. The second groove 32 and the first groove 31 are arranged opposite to each other. The second groove 32 and the first groove 31 enclose to form the first cavity; the first convex member 60 further includes a second convex portion 62. The second convex portion 62 is provided on one of the first plate body 10 and the second plate body 20, and the first convex portion 61 is provided on the other of the first plate body 10 and the second plate body 20. For example, the first convex portion 61 is provided on the first plate body 10, and the second convex portion 62 is provided on the second plate body 20. It can also be that the second convex portion 62 is provided on the first plate body 10, and the first convex portion 61 is provided on the second plate body 20. The second convex portion 62 and the first convex portion 61 are arranged opposite to each other. The second convex portion 62 and the first convex portion 61 enclose to form the second cavity; one of the second convex portion 62 and the first convex portion 61 is provided with a connection hole 63, and the connection hole 63 is used for outputting the fluid.

[0066] In this embodiment, the flow area of the first cavity formed by enclosing the first groove 31 and the second groove 32 here is relatively large. Correspondingly, the second cavity is also defined by enclosing the second convex hull 62 and the first convex hull 61, thereby reducing the influence on the fluid flow rate and making the fluid output more smoothly from the connection hole 63.

[0067] Here, the first cavity formed by enclosing the first groove 31 and the second groove 32 is preferably a circular channel, which is convenient for fluid flow and has a small flow resistance.

[0068] In some alternative embodiments, the swirl suppression part includes a first swirl suppression part 6111 and a second swirl suppression part 6211. Here, for the sake of distinction, the swirl suppression part formed on the first convex hull 61 is called the first swirl suppression part 6111, and the swirl suppression part formed on the second convex hull 62 is called the second swirl suppression part 6211.

[0069] Optionally, the first convex hull 61 has an annular structure, and the surface of the first convex hull 61 facing the fluid is provided with the first swirl suppression part 6111; the second convex hull 62 also has an annular structure, and the surface of the second convex hull 62 facing the fluid is provided with the second swirl suppression part 6211. In the present invention, by providing the first swirl suppression part 6111 on the first convex hull 61, when the fluid flows through the first swirl suppression part 6111, the swirl of the fluid is reduced. By providing the second swirl suppression part 6211 on the second convex hull 62, when the fluid flows through the second swirl suppression part 6211, the swirl of the fluid is reduced, thereby sufficiently reducing the swirl generated by the fluid and reducing the resistance encountered by the fluid.

[0070] It should be noted that the first swirl suppression part 6111 and the second swirl suppression part 6211 can exist alone or simultaneously. That is to say, the first swirl suppression part 6111 can be provided only on the surface of the first convex hull 61 facing the fluid, or the second swirl suppression part 6211 can be provided only on the surface of the second convex hull 62 facing the fluid, both of which can achieve a certain effect of reducing the swirl of the fluid. Of course, the preferred method is to provide the first swirl suppression part 6111 on the surface of the first convex hull 61 facing the fluid and at the same time provide the second swirl suppression part 6211 on the surface of the second convex hull 62 facing the fluid, which can achieve a better effect of suppressing swirl.

[0071] In order to describe the structure of the first convex hull member 60 in more detail, the specific forming mechanism of the first convex hull member 60 will be elaborated below.

[0072] Refer to Figure 2 and Figure 6As shown, the first convex hull 61 includes a first wall body 611 and a second wall body 612; the first wall body 611 is annularly arranged, and a plurality of first swirl suppression parts 6111 are arranged on the surface of the first wall body 611 facing the fluid. The second wall body 612 is arranged at one end of the first wall body 611 away from the second convex hull 62, that is, the second wall body 612 is located at the top of the first wall body 611 and connected to the top of the first wall body 611, thereby forming a part of the outer wall of the second cavity. Refer to Figure 4 and Figure 6 , the second convex hull 62 includes a third wall body 621 and a fourth wall body 622. The third wall body 621 is annularly arranged, and a plurality of second swirl suppression parts 6211 are arranged on the surface of the fourth wall body 622 facing the fluid. The fourth wall body 622 is arranged at one end of the third wall body 621 away from the first convex hull 61, that is, the fourth wall body 622 is located at the bottom end of the second wall body 612 and connected to the bottom end of the second wall body 612, thereby forming a part of the outer wall of the second cavity.

[0073] The first convex hull 61 and the second convex hull 62 of this structure can adopt the same structure. For example, both the first convex hull 61 and the second convex hull 62 are in an oval structure, and the first swirl suppression part 6111 and the second swirl suppression part 6211 are formed on the inner surface of the oval. Among them, the first swirl suppression part 6111 is formed on the first convex hull 61, and the second swirl suppression part 6211 is formed on the second convex hull 62; of course, the first convex hull 61 and the second convex hull 62 here can also be both set to a regular pentagon structure, and the first swirl suppression part 6111 and the second swirl suppression part 6211 are respectively formed at the corners of the pentagon. As long as the first convex hull 61 and the second convex hull 62 are non-circular structures, the first swirl suppression part 6111 and the second swirl suppression part 6211 can be formed on the inner surface, thereby producing the effect of reducing swirl. No further examples will be given here.

[0074] In some alternative embodiments, the first wall body 611 is in a first square structure, and the first swirl suppression parts 6111 are arranged at the four corner positions of the first square structure; and / or the third wall body 621 is a second square structure, and the second swirl suppression parts 6211 are arranged at the four corner positions of the second square structure. The shapes of the first square structure and the second square structure here are the same, and the distinction is made here for the convenience of description. Setting both the first wall body 611 and the second wall body 612 as square structures makes it easy to process connection holes 63 at the central positions on the second wall body 612 and / or the fourth wall body 622, facilitating the smooth outflow of fluid from the position of the connection holes 63.

[0075] Specifically, the connection hole 63 is arranged on the second wall body 612, and the connection hole 63 is arranged at the central position of the second wall body 612, facilitating the outflow of fluid outward through the pipeline connected to the connection hole 63.

[0076] It should be noted that when the first wall body 611 is of a square structure, the first swirl suppressing portions 6111 at the four corner positions are smoothly connected and transitioned, rather than in a right-angled shape. Similarly, when the third wall body 621 is of a square structure, the second swirl suppressing portions 6211 at the four corner positions are smoothly connected and transitioned, rather than in a right-angled shape. In the accompanying drawings of the specification, the position indicated by the first swirl suppressing portion 6111 is outside the first convex hull 61, or the position indicated by the second swirl suppressing portion 6211 is outside the second convex hull 62. This is for the convenience of indication. In fact, both the first swirl suppressing portion 6111 and the second swirl suppressing portion 6211 are located on the inner surface of the first convex hull member 60.

[0077] In some alternative embodiments, the second wall body 612 is parallel to the first plate body 10, and the fourth wall body 622 is parallel to the first plate body 10. Since the first plate body 10 and the second plate body 20 are in a covering and connecting structure, the first plate body 10 and the second plate body 20 form an integral structure. Here, both the second wall body 612 and the fourth wall body 622 are arranged parallel to the first plate body 10, and the processing method is simple.

[0078] It should be noted that Figures 1 to 6 The structures of the first convex hull 61 and the second convex hull 62 of the pipeline integration module 100 shown in [[ ]] are the same as a whole. The difference is that the first convex hull 61 forms a connection hole 63 on the second wall body 612, while the fourth wall body 622 of the second convex hull 62 is of a flat plate structure, and the fourth wall body 622 and the third wall body 621 form a closed cavity.

[0079] The present invention also provides another structure of the pipeline integration module 100, which improves the structure of the pipeline integration module 100 in [[ ]]. The specific structure is as shown in [[ ]]. Figures 1 to 6 The structure of the pipeline integration module 100 in [[ ]] is improved. The specific structure is as shown in [[ ]]. Figures 7 to 10 As shown, Figure 7 Schematically shows another structural schematic diagram (including connecting pipes) of the pipeline integration module 100 according to an embodiment of the present invention. Figure 8 For Figure 7 The structural schematic diagram of the pipeline integration module 100 shown in [[ ]] from the second perspective. Figure 9 For Figure 7 The structural schematic diagram of the pipeline integration module 100 shown in [[ ]] from the third perspective. Figure 10 For Figure 7 The cross-sectional view of the pipeline integration module 100 shown in [[ ]] along the D-D section.

[0080] In the pipeline integration module 100 of this embodiment, the setting of the fourth wall 622 mentioned above is improved. The structure of the first convex hull 61 is the same as that in the previous embodiment, that is, the first convex hull 61 includes a first wall 611 and a second wall 612. The difference is that in the previous embodiment, the fourth wall 622 is arranged parallel to the second plate 20, while in the structure of this embodiment, as Figure 10 shown, the fourth wall 622 is inclined, and the fourth wall 622 is inclined upward along the flow direction of the fluid, that is, inclined in the direction of the connection hole 63. The included angle formed between the fourth wall 622 and the first plate 10 is α, and α is between 0 and 45 degrees, for example, it can be 30 degrees or 35 degrees, etc. At this time, the fourth wall 622 functions as a flow guide plate, which can play a role in guiding the flow during the process of the fluid flowing from the first cavity to the second cavity, further reducing the resistance of the fluid, thereby reducing the pressure drop of the pipeline system.

[0081] In addition, when the angle of α is 45 degrees, the flow guiding effect of the fourth wall 622 is the best, which can make the fluid flow out more smoothly.

[0082] In addition, due to the inclined setting of the fourth wall 622, the shape of the third wall 621 needs to be modified adaptively, that is, part of the entity of the third wall 621 is removed and used in cooperation with the inclined fourth wall 622. At this time, the shape of the fourth wall 622 changes from the original square plate shape to a rectangular plate shape, and the third wall 621 changes from the original regular ring structure to an irregular ring structure.

[0083] Regardless of the structure shown in Figure 1 or the structure shown in Figure 7 of the pipeline integration module 100, after being connected to the external pipeline, the pressure drop of the air conditioner outdoor unit 200 can be significantly reduced, greatly improving the overall performance of the air conditioner system, and further improving the refrigeration and heating capabilities of the air conditioner system.

[0084] In some alternative embodiments, the connection hole 63 is a flanged hole. By setting the connection hole 63 as a flanged hole, the contact area with the external connection pipe to be connected can be increased, preventing leakage at the connection position.

[0085] In some alternative embodiments, the flanging height of the connection hole 63 is 1 mm to 4 mm. When connecting to the connecting pipe, a soldering process is usually adopted. The solder can be filled at the contact surface between the inner surface of the connection hole 63 and the outer surface of the connecting pipe, and then they are connected by welding. Setting the flanging height of the connection hole 63 to 1 to 4 mm can ensure an appropriate contact area between the connection hole 63 and the connecting pipe, meet the sealing performance, and save the amount of solder. For example, setting the flanging height of the connection hole 63 to 2 mm or 3 mm can meet the sealing performance requirements and reduce the amount of solder.

[0086] When the flanging height of the connection hole 63 is less than 1 mm, such as 0.5 mm, the contact area between the connection hole 63 and the connecting pipe will be relatively small, and the weld formed after welding will be relatively thin, and fluid leakage is likely to occur when working under high pressure. On the contrary, if the flanging height of the connection hole 63 is greater than 4 mm, the contact area between the connection hole 63 and the connecting pipe will be relatively large, and more solder needs to be filled at the contact surface between the connection hole 63 and the connecting pipe, resulting in an increase in the amount of solder used and an increase in the manufacturing cost of the air conditioner outdoor unit 200.

[0087] Optionally, the first plate body 10 is further provided with a second convex member 70 at the inlet end of the first integrated pipe 30. A second connecting pipe 202 is connected to the second convex member 70, and the inflow of fluid is realized through the second connecting pipe 202. The second convex member 70 here includes a third convex part 71 and a fourth convex part 72. Among them, the third convex part 71 is in a circular ring shape, and the inner surface of the third convex part 71 is smooth. The fourth convex part 72 is arranged in cooperation with the third convex part 71, and the fourth convex part 72 is in a spherical arc shape.

[0088] In the prior art, the inner surface of the third convex part 71 is in a stepped surface shape, which will increase the flow resistance of the fluid. In the present invention, the inner surface of the third convex part 71 is set to be smooth, which can reduce the flow resistance of the fluid.

[0089] According to the second aspect of the embodiment of the present invention, an air conditioner outdoor unit 200 is proposed, which includes a connecting pipe and the pipeline integration module 100 mentioned in the above embodiment, and the connecting pipe is connected to the pipeline integration module 100. Among them, the connecting pipe is connected to the pipeline integration module 100 at the position of the connection hole 63.

[0090] In addition to these structures, the air conditioner outdoor unit 200 also includes a compressor, a low-pressure tank, an electronic expansion valve, an outdoor heat exchanger, etc. These are all common components in the prior art and will not be elaborated here.

[0091] Next, the setting of the connecting pipe and the connection structure of the pipeline will be further described with reference to the drawings.

[0092] Continue to refer toFigure 1 As shown in Figure 1 , three pipelines are integrated, namely the first integrated pipe 30, the second integrated pipe 40, and the third integrated pipe 50. Therefore, the number of connecting pipes is multiple. In Figure 1 , the number of connecting pipes is five, all of which play a role in fluid flow. For the convenience of description here, the multiple connecting pipes are divided into the first connecting pipe 201, the second connecting pipe 202, the third connecting pipe 203, the fourth connecting pipe 204, and the fifth connecting pipe 205. Among them, the first connecting pipe 201 is fixedly connected to the first convex part 41 of the second integrated pipe 40. One end of the first connecting pipe 201 is the first inlet 2011 for fluid to flow in. The other end of the second integrated pipe 40 is provided with a second convex part 42, and one end of the third connecting pipe 203 is connected to the second convex part 42; the inlet position of the third integrated pipe 50 is provided with a third convex part 51, and the other end of the third connecting pipe 203 is connected to the third convex part 51. That is to say, the third connecting pipe 203 is used to connect the second integrated pipe 40 and the third integrated pipe 50. The outlet position of the third integrated pipe 50 is provided with a fourth convex part 52, and the fourth connecting pipe 204 is connected to the fourth convex part 52. One end of the fourth connecting pipe 204 is the first outlet 2041, that is, the top end of the fourth connecting pipe 204 is the first outlet 2041. Here, the first convex part 41, the third convex part 51, and the second convex part 70 are all arranged at the inlet ends of the corresponding integrated pipes. Specifically, the first convex part 41 is arranged at the inlet end of the second integrated pipe 40, the third convex part 51 is arranged at the inlet end of the third integrated pipe 50, and the second convex part 70 is arranged at the inlet end of the first integrated pipe 30. The structures of the first convex part 41, the third convex part 51, and the second convex part 70 can be the same or different. And the second convex part 42, the fourth convex part 52, and the first convex part 60 are all arranged at the outlet ends of the corresponding integrated pipes. Specifically, the second convex part 42 is arranged at the outlet end of the second integrated pipe 40, the fourth convex part 52 is arranged at the outlet end of the third integrated pipe 50, and the first convex part 60 is arranged at the outlet end of the first integrated pipe 30. The structures of the second convex part 42, the fourth convex part 52, and the first convex part 60 are the same. That is to say, the structures of the second convex part 42 and the fourth convex part 52 are both the same as the structure of the first convex part 60. Here, the specific structures of the second convex part 42 and the fourth convex part 52 will not be further elaborated.

[0093] In addition, it should be noted that the connecting pipes here include two shapes: straight pipes and bent pipes. Among them, the first connecting pipe 201, the second connecting pipe 202, and the fourth connecting pipe 204 are all straight pipes, while the third connecting pipe 203 is U-shaped, and the fifth connecting pipe 205 is bent. Whether it is a straight pipe or a bent pipe, the cross-section of the connecting pipe is circular, which is a common shape in the prior art and is convenient for connecting with the corresponding connecting holes 63.

[0094] The following are the relevant data of two pipeline integration modules 100 in the present invention during the actual application process and the comparison results with the prior art.

[0095] There are two fluid pipelines involved in the present invention, a first fluid pipeline and a second pipe body pipeline. The first fluid pipeline is the main valve pipeline, and the second fluid pipeline is the four-way valve return air pipeline. As Figure 1 shown, the first fluid pipeline starts from the first inlet 2011 of the first connecting pipe 201, and successively passes through the first connecting pipe 201, the second integrated pipe 40, the third connecting pipe 203, the third integrated pipe 50, and the fourth connecting pipe 204, and ends at the first outlet 2041. The second fluid pipeline starts from the second inlet 2021 of the second connecting pipe 202, and successively passes through the second connecting pipe 202, the first integrated pipe 30, and the fifth connecting pipe 205, and ends at the second outlet 2051 of the fifth connecting pipe 205.

[0096] The first fluid pipeline here includes six sections of pipelines, which are successively the first section, the second section, the third section, the fourth section, the fifth section, and the sixth section according to the flow direction of the fluid. Among them, the first section is between the two ends of the first connecting pipe 201, the second section is between the two ends of the second integrated pipe 40, the third section is the outlet of the second integrated pipe 40 and the inlet of the third connecting pipe 203, the fourth section is between the two ends of the third connecting pipe 203, the fifth section is between the two ends of the third integrated pipe 50, and the sixth section is between the two ends of the fourth connecting pipe 204.

[0097] The second fluid pipeline includes five parts, which are successively the first part, the second part, the third part, the fourth part, and the fifth part according to the flow direction of the fluid. Among them, the first part is between the two ends of the second connecting pipe 202, the second part is between the outlet position of the first connecting pipe 201 and the inlet of the first integrated pipe 30, the third part is between the two ends of the first integrated pipe 30, the fourth part is between the outlet of the first integrated pipe 30 and the inlet of the fifth connecting pipe 205, and the fifth part is between the two ends of the fifth connecting pipe 205.

[0098] In addition, the first inlet 2011 and the first outlet 2041 are the two ends of the first fluid pipeline, and the second inlet 2021 and the second outlet 2051 are the two ends of the second fluid pipeline. This function is realized by the ports of the connecting pipes.

[0099] When the pipeline integration module 100 adopts the Figure 1 structure, the specific results of the simulation test are as follows:

[0100] The pressure drop of the first section in the first fluid pipeline is 86.2 Pa, and the proportion of the pressure drop is 0.2%. The pressure drop of the second section is 5401.9 Pa, and the proportion of the pressure drop is 10.8%. The pressure drop of the third section is 17703 Pa, and the proportion of the pressure drop is 35.4%. The pressure drop of the fourth section is 3744.5 Pa, and the proportion of the pressure drop is 7.5%. The pressure drop of the fifth section is 23008.6 Pa, and the proportion of the pressure drop is 46%. The pressure drop of the sixth section is 103 Pa, and the proportion of the pressure drop is 0.2%. The total pressure drop is 50046.9 Pa.

[0101] In the second fluid pipeline, the pressure drop of the first part is 252.4 Pa, and the proportion of the pressure drop is 0.6%. The pressure drop of the second part is 8001.1 Pa, and the proportion of the pressure drop is 17.6%. The pressure drop of the third part is 8480.5 Pa, and the proportion of the pressure drop is 18.6%. The pressure drop of the fourth part is 19796.2 Pa, and the proportion of the pressure drop is 43.5%. The pressure drop of the fifth part is 8959.5 Pa, and the proportion of the pressure drop is 19.7%. The total pressure drop is 45489.7 Pa.

[0102] When the pipeline integration module 100 adopts the Figure 7 structure, the results of the simulation test are as follows:

[0103] The pressure drop of the first section in the first fluid pipeline is 86 Pa, and the proportion of the pressure drop is 0.2%. The pressure drop of the second section is 2092 Pa, and the proportion of the pressure drop is 4.2%. The pressure drop of the third section is 3375 Pa, and the proportion of the pressure drop is 6.8%. The pressure drop of the fourth section is 18094 Pa, and the proportion of the pressure drop is 36.4%. The pressure drop of the fifth section is 22580 Pa, and the proportion of the pressure drop is 45.4%. The pressure drop of the sixth section is 191 Pa, and the proportion of the pressure drop is 0.4%. The total pressure drop is 49755 Pa.

[0104] In the second fluid pipeline, the pressure drop of the first part is 263 Pa, and the proportion of the pressure drop is 0.7%. The pressure drop of the second part is 7579 Pa, and the proportion of the pressure drop is 20.3%. The pressure drop of the third part is 10694 Pa, and the proportion of the pressure drop is 28.7%. The pressure drop of the fourth part is 15048 Pa, and the proportion of the pressure drop is 40.4%. The pressure drop of the fifth part is 3709 Pa, and the proportion of the pressure drop is 9.9%. The total pressure drop is 37294 Pa.

[0105] In the prior art, the second convex part 42, the fourth convex part 52 and the first convex part 60 all adopt a circular structure. The total pressure drop of the first fluid pipeline is 631000 Pa, the pressure drop of the third section is 64752 Pa, and the proportion of the pressure drop is 69.39%. The total pressure drop of the second fluid pipeline is 851000 Pa, the pressure drop of the fourth part is 655670 Pa, and the proportion of the pressure drop is 80.43%.

[0106] It can be known by comparison that the structures of the pipeline integration module 100 in the present invention can significantly reduce the pressure drop of the first fluid pipeline and the pressure drop of the second fluid pipeline, reduce the proportion of the pressure drop of the fifth section in the first fluid pipeline, and the proportion of the pressure drop of the fourth part in the second fluid pipeline.

[0107] Specifically, when the pipeline integration module 100 is Figure 1 the structure in, that is, the second convex part 42, the fourth convex part 52 and the first convex hull part 60 are all square structures and have exactly the same structure, and when the second wall body 612 of the first convex hull 61 is arranged in parallel with the first plate body 10, the pipeline integration module 100 can reduce the pressure drop of the first fluid pipeline from 631000 Pa in the prior art to 50046.9 Pa, and the pressure drop is reduced by 92.07%. And it can reduce the pressure drop of the second fluid pipeline from 851000 Pa in the prior art to 45489.7 Pa, and the pressure drop is reduced by 94.65%, significantly reducing the pressure loss of the pipeline system.

[0108] When the pipeline integration module 100 is Figure 7 the structure in, that is, the second convex part 42, the fourth convex part 52 and the first convex hull part 60 are all square structures and have exactly the same structure. However, the sizes can be the same or different. When the second wall body 612 of the first convex hull 61 is arranged obliquely, the pipeline integration module 100 can reduce the pressure drop of the first fluid pipeline from 631000 Pa in the prior art to 49755 Pa, and the pressure drop is reduced by 92.11%. And it can reduce the pressure drop of the second fluid pipeline from 851000 Pa in the prior art to 37294 Pa, and the pressure drop is reduced by 95.62%, significantly reducing the pressure loss of the pipeline system.

[0109] In addition, compared with the structure shown in Figure 7 in the present invention, while the fourth wall body 622 realizes the sealing of the second cavity, it can also realize the function of guiding the flow, making the flow of the fluid smoother and flowing out smoothly from the position of the connection hole 63. Since the second convex part 42 and the fourth convex part 52 both adopt the same structure as the first convex hull part 60, they can all achieve a better flow guiding effect, more significantly reducing the pressure drops of the first fluid pipeline and the second fluid pipeline, and having a better effect of reducing the pressure loss.
