To describe the structure of the first convex bag member 60 in more detail, a specific forming mechanism of the first convex bag member 60 will be explained below.
Referring to fig. 2 and 6, the first convex hull 61 includes a first wall 611 and a second wall 612; the first wall 611 is disposed in a ring shape, the surface of the first wall 611 facing the fluid is provided with a plurality of first rotational flow inhibiting portions 6111, and the second wall 612 is disposed at an end of the first wall 611 far away from the second convex hull 62, that is, the second wall 612 is located at a top end of the first wall 611 and connected with a top portion of the first wall 611, thereby forming a part of an outer wall of the second cavity. Referring to fig. 4 and 6, the second convex hull 62 includes a third wall 621 and a fourth wall 622, the third wall 621 is disposed in a ring shape, a surface of the fourth wall 622 facing the fluid is provided with a plurality of second rotational flow stoppers 6211, and the fourth wall 622 is disposed at an end of the third wall 621 away from the first convex hull 61, that is, the fourth wall 622 is located at a bottom end of the second wall 612 and connected to the bottom end of the second wall 612, thereby forming a portion of an outer wall of the second cavity.
The first convex hull 61 and the second convex hull 62 of such a structure may adopt the same structure, for example, the first convex hull 61 and the second convex hull 62 are both in an elliptical structure, and a first rotational flow suppression portion 6111 and a second rotational flow suppression portion 6211 are formed on the inner surface of the ellipse, wherein the first rotational flow suppression portion 6111 is formed on the first convex hull 61, and the second rotational flow suppression portion 6211 is formed on the second convex hull 62; of course, the first convex hull 61 and the second convex hull 62 may be both provided with regular pentagon structures, and the first rotational flow suppression part 6111 and the second rotational flow suppression part 6211 may be formed at the positions of the corners of the pentagon, respectively, so long as the first convex hull 61 and the second convex hull 62 are non-circular structures, the first rotational flow suppression part 6111 and the second rotational flow suppression part 6211 may be formed on the inner surface, thereby generating the effect of reducing the rotational flow, which is not illustrated here.
In some alternative embodiments, the first wall 611 has a first square structure, and the first swirling flow suppressing portions 6111 are disposed at four corner positions of the first square structure; and/or the third wall 621 is a second square structure, and the second swirling flow suppressing portions 6211 are provided at four corner positions of the second square structure, where the shapes of the first square structure and the second square structure are identical, which is a distinction for convenience of description. By arranging first wall 611 and second wall 612 in a square configuration, connection hole 63 is easily formed at a central position of second wall 612 and/or fourth wall 622, so that fluid can smoothly flow out from the position of connection hole 63.
Specifically, the connection hole 63 is disposed on the second wall 612, and the connection hole 63 is disposed at a central position of the second wall 612, so as to facilitate the fluid flowing out through the pipeline connected with the connection hole 63.
When the first wall body 611 has a square structure, the first swirling flow suppressing portions 6111 at the four corner positions are smoothly connected and transited, and are not in a right-angled shape. Similarly, when the third wall 621 has a square structure, the second swirling flow suppressing portions 6211 at the four corner positions are smoothly connected and transited, and are not in a right-angled shape, and in the drawings of the specification, the position indicated by the first swirling flow suppressing portion 6111 is the outside of the first convex hull 61, or the position indicated by the second swirling flow suppressing portion 6211 is the outside of the second convex hull 62, for the sake of convenience of indication, and actually, the first swirling flow suppressing portion 6111 and the second swirling flow suppressing portion 6211 are both located on the inner surface of the first convex hull member 60.
In some alternative embodiments, the second wall 612 is parallel to the first plate 10, and the fourth wall 622 is parallel to the first plate 10, and since the first plate 10 and the second plate 20 are connected in a covering manner, the first plate 10 and the second plate 20 are formed as a single structure, and the second wall 612 and the fourth wall 622 are both parallel to the first plate 10, which is easy to manufacture.
It should be noted that the structures of the first convex hull 61 and the second convex hull 62 of the pipeline integration module 100 shown in fig. 1 to 6 are the same as a whole, except that the first convex hull 61 forms the connection hole 63 on the second wall 612, the fourth wall 622 of the second convex hull 62 is a flat plate-shaped structure, and the fourth wall 622 and the third wall 621 form a closed cavity.
The present invention further provides another structure of a pipeline integration module 100, which is an improvement of the structure of the pipeline integration module 100 in fig. 1 to 6, and the specific structure is shown in fig. 7 to 10, fig. 7 schematically shows another structural schematic diagram (including a connecting pipe) of the pipeline integration module 100 according to an embodiment of the present invention, fig. 8 is a structural schematic diagram of the pipeline integration module 100 shown in fig. 7 at a second viewing angle, fig. 9 is a structural schematic diagram of the pipeline integration module 100 shown in fig. 7 at a third viewing angle, and fig. 10 is a cross-sectional view taken along a D-D section in fig. 7.
The pipe integration module 100 in this embodiment is modified from the aforementioned arrangement of the fourth wall 622, and 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 the first wall 611 and the second wall 612, except that in the previous embodiment, the fourth wall 622 and the second plate 20 are arranged in parallel, and in this structure of this embodiment, as shown in fig. 10, the fourth wall 622 is arranged obliquely, and the fourth wall 622 is arranged obliquely upward along the flowing direction of the fluid, that is, obliquely toward the side 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, 30 degrees or 35 degrees. The fourth wall 622 plays a role of a flow guide plate at this time, and can play a role of flow guide in the process that the fluid flows from the first cavity to the second cavity, so that the resistance of the fluid is further reduced, and the pressure drop of the pipeline system is reduced.
When the angle α is 45 degrees, the fourth wall 622 has the best flow guiding effect, and the fluid can flow out more smoothly.
In addition, since the fourth wall 622 is disposed obliquely, the shape of the third wall 621 needs to be modified adaptively, that is, a part of the third wall 621 is removed and used in cooperation with the oblique fourth wall 622, at this time, the shape of the fourth wall 622 is changed from the original square plate shape to the rectangular plate shape, and the shape of the third wall 621 is changed from the original regular ring structure to the irregular ring structure.
Whether the pipe integrated module 100 has the structure shown in fig. 1 or the structure shown in fig. 7, after being connected to an external pipe, the pressure drop of the outdoor unit 200 of the air conditioner can be significantly reduced, and the overall performance of the air conditioning system can be greatly improved, thereby improving the cooling and heating capabilities of the air conditioning system.
In some alternative embodiments, the connection hole 63 is a flanged hole, and by setting the connection hole 63 as a flanged hole, the contact area with the connection pipe to be connected to the outside can be increased, and the leakage at the connection position can be prevented.
In some alternative embodiments, the height of the flange of the connecting hole 63 is 1 mm to 4 mm, and when the connecting hole is connected to the connecting pipe, a brazing process is usually adopted, and the connecting hole can be connected by filling brazing filler metal at a contact surface position between the inner surface of the connecting hole 63 and the outer surface of the connecting pipe and then welding. The height of the flanging of the connecting hole 63 is set to be 1-4 mm, so that the contact area between the connecting hole 63 and the connecting pipe is ensured to be moderate, the sealing performance is met, and the using amount of brazing filler metal is saved. For example, the height of the flange of the connecting hole 63 is set to be 2 mm or 3 mm, etc., which can meet the requirement of sealing performance and reduce the consumption of brazing filler metal.
When the height of the flange of the connecting hole 63 is less than 1 mm, for example, the height of the flange is 0.5 mm, the contact area between the connecting hole 63 and the connecting pipe is small, the weld formed after welding is thin, and the condition of fluid leakage is easy to occur when the connecting pipe works under high pressure. On the contrary, if the height of the flange of the connection hole 63 is greater than 4 mm, the contact area between the connection hole 63 and the connection pipe is large, and more brazing filler metal is required to be filled in the contact surface between the connection hole 63 and the connection pipe, so that the amount of the brazing filler metal is increased, and the manufacturing cost of the outdoor unit 200 of the air conditioner is increased.
Optionally, the first plate body 10 is further provided with a second convex bag member 70 at the inlet end of the first integrated pipe 30, and a second connecting pipe 202 is connected to the second convex bag member 70, and the inflow of the fluid is realized through the second connecting pipe 202. The second convex hull element 70 here comprises a third convex hull 71 and a fourth convex hull 72, wherein the third convex hull 71 is circular and the inner surface of the third convex hull 71 is smooth, the fourth convex hull 72 is fitted with the third convex hull 71, and the fourth convex hull 72 is in the shape of a spherical arc.
In the prior art, the inner surface of the third convex hull 71 is in a step surface shape, so that the flow resistance of the fluid is increased.
According to a second aspect of the embodiments of the present invention, there is provided an outdoor unit 200 of an air conditioner, which includes a pipe integrated module 100 mentioned in the above embodiments, and a connecting pipe, which is connected to the pipe integrated module 100. Wherein the connection pipe is connected to the pipe integration module 100 at the position of the connection hole 63.
The outdoor unit 200 includes a compressor, a low pressure tank, an electronic expansion valve, an outdoor heat exchanger, etc., which are common components in the prior art, and will not be described herein.

Specifically, when the pipe integrated module 100 is in the structure shown in fig. 1, that is, the second protruding portion 42, the fourth protruding portion 52 and the first convex hull member 60 are all in a square structure, and the structure is completely consistent, and the second wall 612 of the first convex hull 61 and the first plate body 10 are arranged in parallel, the pipe integrated module 100 can reduce the pressure drop of the first fluid pipe from 631000Pa in the prior art to 50046.9Pa, and reduce the pressure drop by 92.07%, and can reduce the pressure drop of the second fluid pipe from 851000Pa in the prior art to 45489.7Pa, and reduce 94.65%, and significantly reduce the pressure loss of the pipe system.
When the pipe integrated module 100 has the structure shown in fig. 7, the second protruding portion 42, the fourth protruding portion 52 and the first protruding member 60 are all square structures, and the structures are identical, but the sizes may be the same or different. In the case that the second wall 612 of the first convex hull 61 is disposed in an inclined manner, the pipeline integration module 100 can reduce the pressure drop of the first fluid pipeline from 631000Pa in the prior art to 49755Pa, and reduce the pressure drop by 92.11%, and can reduce the pressure drop of the second fluid pipeline from 851000Pa in the prior art to 37294Pa, and reduce the pressure drop by 95.62%, thereby significantly reducing the pressure loss of the pipeline system.
In addition, compared with the structure shown in fig. 1, the structure shown in fig. 7 of the present invention can also achieve the function of guiding the flow while the fourth wall 622 achieves sealing of the second cavity, so that the fluid can flow more smoothly and smoothly out of the position of the connection hole 63. Because the second convex part 42 and the fourth convex part 52 are both of the same structure as the first convex bag part 60, better flow guide effect can be achieved, the pressure drop of the first fluid pipeline and the second fluid pipeline is reduced more obviously, and the effect of reducing pressure loss is better.
