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, the surface of the fourth wall 622 facing the fluid is provided with a plurality of second rotational flow restraining portions 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 disposed at a bottom end of the second wall 612 and connected with the bottom end of the second wall 612, thereby forming a part of an outer wall of the second cavity.

The first convex hull 61 and the second convex hull 62 of this structure may adopt the same structure, for example, the first convex hull 61 and the second convex hull 62 each have an elliptical structure, and a first swirling flow suppressing portion 6111 and a second swirling flow suppressing portion 6211 are formed on the inner surface of the ellipse, wherein the first swirling flow suppressing portion 6111 is formed on the first convex hull 61, and the second swirling flow suppressing portion 6211 is formed on the second convex hull 62; of course, the first convex hull 61 and the second convex hull 62 may each be formed in a regular pentagon structure, and the first swirling flow suppressing portion 6111 and the second swirling flow suppressing portion 6211 may be formed at the positions of the corners of the pentagon, so long as the first convex hull 61 and the second convex hull 62 are formed in a non-circular structure, the first swirling flow suppressing portion 6111 and the second swirling flow suppressing portion 6211 may be formed on the inner surfaces thereof, thereby producing the swirling flow reducing effect, and will not be illustrated here.

The first wall body 611 and the second wall body 612 are both square structures, so that the connecting hole 63 is easily machined at the center position of the second wall body 612 and/or the fourth wall body 622, and fluid can conveniently and smoothly flow out from the position of the connecting 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 that fluid can flow out through a pipeline connected to 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 have a rounded connection transition, and are not rectangular. 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 transition, and are not rectangular, 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, which is for convenience of indication, and in fact, 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 60.

In some alternative embodiments, the second wall 612 is parallel to the first plate 10, the fourth wall 622 is parallel to the first plate 10, and since the first plate 10 and the second plate 20 are in a structure of covering connection, the first plate 10 and the second plate 20 are formed as a single structure, and here, the second wall 612 and the fourth wall 622 are both arranged parallel to the first plate 10, and the processing manner is simple.

It should be noted that the structures of the first convex hull 61 and the second convex hull 62 of the pipeline integrated module 100 shown in fig. 1 to 6 are the same as each other, and the difference is 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 structure, and the fourth wall 622 and the third wall 621 form a closed cavity.

The present utility model further provides another structure of the pipeline integrated module 100, the structure of the pipeline integrated module 100 in fig. 1 to 6 is improved, the specific structure is shown in fig. 7 to 10, fig. 7 schematically shows another schematic structure of the pipeline integrated module 100 (including a connection pipe) according to an embodiment of the present utility model, fig. 8 is a schematic structure of the pipeline integrated module 100 shown in fig. 7 at a second viewing angle, fig. 9 is a schematic structure of the pipeline integrated module 100 shown in fig. 7 at a third viewing angle, and fig. 10 is a cross-sectional view along the D-D section in fig. 7.

The piping integrated module 100 in the present embodiment improves the arrangement of the fourth wall 622 mentioned above, 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, whereas in this structure of the present embodiment, as shown in fig. 10, the fourth wall 622 is arranged obliquely, and the fourth wall 622 is arranged obliquely upward in the flow direction of the fluid, that is, obliquely to the side of the connection hole 63. The fourth wall 622 forms an angle α with the first plate 10, and α is between 0 and 45 degrees, for example, 30 degrees or 35 degrees. The fourth wall 622 at this time serves as a deflector, and may serve as a deflector during the flow of fluid from the first chamber to the second chamber, further reducing the resistance of the fluid, and thus the pressure drop of the pipeline system.

In addition, when the angle α is 45 degrees, the flow guiding effect of the fourth wall 622 is good, and the fluid can flow out more smoothly.

In addition, since the fourth wall 622 is inclined, 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 combination with the inclined fourth wall 622, the shape of the fourth wall 622 is changed from the original square plate shape to the rectangular plate shape, and the third wall 621 is changed from the original regular ring structure to the irregular ring structure.

The pipe integrated module 100, whether it is the structure shown in fig. 1 or the structure shown in fig. 7, can significantly reduce the pressure drop of the air conditioner outdoor unit 200 after being connected with an external pipe, greatly improve the overall performance of the air conditioning system, and further improve the cooling and heating capacities of the air conditioning system.

In some alternative embodiments, the connection hole 63 is a flanging hole, and by providing the connection hole 63 as a flanging hole, the contact area with the external connection pipe to be connected can be increased, thereby preventing leakage at the connection position.

In some alternative embodiments, the flange height of the connection hole 63 is 1 mm to 4 mm, and when connecting with the connection pipe, it is usually a brazing process, and may be connected by filling a brazing material at a contact surface position between an inner surface of the connection hole 63 and an outer surface of the connection pipe and then welding. The flanging height of the connecting hole 63 is set to be 1 to 4 millimeters, so that the moderate contact area between the connecting hole 63 and the connecting pipe can be ensured, the sealing performance is met, and the using amount of brazing filler metal is saved. For example, the flange height of the connecting hole 63 is set to 2 mm or 3 mm, etc. to meet the requirement of sealing performance, and the amount of brazing filler metal is reduced.

When the flange height of the connection hole 63 is less than 1 mm, for example, the flange height is 0.5 mm, the contact area between the connection hole 63 and the connection pipe is small, the weld formed after welding is thin, and fluid leakage is easy 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 connection pipe is larger, more brazing filler metal is required to be filled at the contact surface between the connection hole 63 and the connection pipe, so that the amount of brazing filler metal is increased, and the manufacturing cost of the air conditioner outdoor unit 200 is increased.

Optionally, the first plate body 10 is further provided with a second convex hull part 70 at the inlet end of the first integrated pipe 30, and the second convex hull part 70 is connected with a second connecting pipe 202, so that the inflow of the fluid is realized through the second connecting pipe 202. The second convex hull 70 includes a third convex hull 71 and a fourth convex hull 72, where the third convex hull 71 is in a ring shape, the inner surface of the third convex hull 71 is smooth, the fourth convex hull 72 is matched with the third convex hull 71, and the fourth convex hull 72 is in a spherical arc shape.

In the prior art, the inner surface of the third convex hull 71 is in a stepped shape, which increases the flow resistance of the fluid, and the inner surface of the third convex hull 71 is provided with a smooth curved surface in the present utility model, which can reduce the flow resistance of the fluid.

Specifically, when the pipeline integrated module 100 is in the structure in fig. 1, that is, the second boss 42, the fourth boss 52 and the first convex hull 60 are all square structures, and the structures are completely identical, in the case that the second wall 612 of the first convex hull 61 is disposed in parallel with the first plate 10, the pipeline integrated module 100 can reduce the pressure drop of the first fluid pipeline from 631000Pa in the prior art to 50046.9Pa, reduce the pressure drop by 92.07%, and can reduce the pressure drop of the second fluid pipeline from 851000Pa in the prior art to 45489.7Pa, reduce the pressure drop by 94.65%, and obviously reduce the pressure loss of the pipeline system.

When the pipeline integrated module 100 is in the structure of fig. 7, that is, the second boss 42, the fourth boss 52 and the first boss 60 are all square structures and completely identical in structure, however, the sizes may be the same or different. In the case that the second wall 612 of the first convex hull 61 is obliquely disposed, the pipeline integrated module 100 can reduce the pressure drop of the first fluid pipeline from 631000Pa in the prior art to 49755Pa, reduce the pressure drop by 92.11%, reduce the pressure drop of the second fluid pipeline from 851000Pa in the prior art to 37294Pa, reduce the pressure drop by 95.62%, and obviously reduce the pressure loss of the pipeline system.
