Description

Technical Field

[0001] The present invention relates to the technical field of manufacturing cooling devices, and particularly to an integrated water vector atomization core and a manufacturing method thereof. Background Art

[0002] A water vector atomization core is a component used for installation in a cooling tower. The Chinese patent document with the publication number CN117245070A discloses a manufacturing method of a water vector atomization core. This manufacturing method uses a cast aluminum alloy combined with welding to weld a flange water pipe to a main body seat formed by aluminum alloy casting to obtain a water vector atomization core. The Chinese patent document with the publication number CN117464323A discloses a water vector core and a manufacturing method thereof. In this manufacturing method, a plurality of side enclosing members are enclosed and then welded to obtain a water vector core.

[0003] However, in the prior art, the water vector atomization core is formed into a whole by welding a plurality of components. Since there are many components, it means there are many welds. Moreover, the space between any adjacent components is narrow, and it is difficult for a welding torch to reach into the components unobstructed for welding, resulting in too low welding efficiency and great difficulty in mass production. Secondly, since the core needs to be used under a relatively high water pressure (for example, ≥0.1 MPa), the quality requirements for the welds are high. As the number of welds increases, the risk of incomplete sealing and leakage will increase, and the subsequent maintenance risk is high. Finally, with many components and many welds, the risk of deformation of its overall structure increases. Therefore, in order to solve the above problems, the present application provides an integrated water vector atomization core and a manufacturing method thereof. Summary of the Invention

[0035] To facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Preferred embodiments of the present invention are shown in the drawings.

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0038] In the embodiments of the present invention, unless otherwise clearly defined and limited, the terms "installation", "connection", "linkage", "fixation", etc. shall be understood in a broad sense. For example, it may be a fixed connection or a detachable connection; it may be a mechanical connection or an electrical connection; it may be a direct connection or an indirect connection through an intermediate medium. It may be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0039] As Figures 1 to 4 shown, an integrated water vector atomization core 10 includes a seat body 100. An axial cavity 110 is provided at the axis of the seat body 100. At least two water distribution pipes 200, which are integrally formed on the outer side wall of the seat body 100 and are circumferentially and equally angularly distributed, and the included angle between the axis of each water distribution pipe 200 and the axis of the seat body 100 is α, where 0° < α < 180°. A flange 300 is also integrally formed at one end of the water distribution pipe 200 away from the seat body 100. At least one water outlet hole 210 is provided on each flange 300. Each water outlet hole 210 penetrates through the water distribution pipe 200 to communicate with the axial cavity 110.

[0040] It should be noted that the integrated water vector atomization core 10 of the present application is integrally formed by a seat body 100, at least two water distribution pipes 200, and a flange 300. An axially penetrating axial cavity 110 is provided in the axial direction of the seat body 100. In this way, it is ensured that the casting core can be smoothly withdrawn from the axial cavity 110 after the core is cast. Further, the water distribution pipes 200 are circumferentially and equally angularly distributed on the outer side wall of the seat body 100, and the number of the water distribution pipes 200 is at least two. In this way, it is ensured that the core can maintain balance during rotation. Further, for example, the number of the water distribution pipes 200 can also be set to ten, or sixteen, or eighteen, or twenty-four, and so on. For each water distribution pipe 200, the included angle between the axis of the water distribution pipe 200 and the axis of the axial cavity 110 is greater than 0° and less than 180°. Specifically, for the convenience of description, the seat body 100 is placed vertically. When α = 90°, the water distribution pipe 200 extends radially outward along the seat body 100 and is in a horizontal state; when 0° < α < 90°, the water distribution pipe 200 is in an upward state relative to the seat body 100; when 90° < α < 180°, the water distribution pipe 200 is in a downward state relative to the seat body 100. Further, a flange 300 is formed at the end of each water distribution pipe 200 away from the seat body 100. At least one water outlet hole 210 is axially provided on each flange 300, and each water outlet hole 210 communicates with the axial cavity 110. Among them, the positions of the water outlet holes 210 on each flange 300 are the same. In this way, it is ensured that the integrated water vector atomization core 10 can maintain balance during rotation when in use. In this way, compared with the core formed by welding several components through a welding process in the prior art, the core of the present application is an integrated core formed by a casting process, which can avoid the risks of incomplete sealing and leakage due to welding, has a low subsequent maintenance probability, and is reliable in use; moreover, without welding, it means that the overall structure of the core will not be deformed due to welding, so the manufacturing accuracy is higher; finally, the existing core needs to be formed by a large number of weldings of multiple components, while the integrated water vector atomization core 10 of the present application can be cast and formed through a set of casting molds, removing the welding process and being easy for mass production.

[0041] Such as Figure 1 and Figure 3As shown, in one embodiment, a water outlet hole 210 is formed in each flange 300, and the positions of the water outlet holes 210 on each flange 300 are the same, so that the integrated water vector atomization core 10 is formed into a single-layer water outlet structure. Further, in another embodiment, two water outlet holes 210 are formed in each flange 300, and the two water outlet holes 210 are distributed at intervals along the axis of the axial cavity 110, and the positions of the water outlet holes 210 on each flange 300 are the same, so that the integrated water vector atomization core 10 is formed into a double-layer water outlet structure. Further, in yet another embodiment, three water outlet holes 210 are formed in each flange 300, and the three water outlet holes 210 are distributed at intervals along the axis of the axial cavity 110, and the positions of the water outlet holes 210 on each flange 300 are the same, so that the integrated water vector atomization core 10 is formed into a triple-layer water outlet structure. Thus, when the number of water outlet holes 210 formed in any flange 300 is several, the integrated water vector atomization core 10 is formed into a water outlet structure of the corresponding layer. For the convenience of understanding the technology, this application gives embodiments of the single-layer water outlet structure, the double-layer water outlet structure, and the triple-layer water outlet structure, but it should not be understood that only the integrated water vector atomization core 10 of the single-layer water outlet structure, the double-layer water outlet structure, and the triple-layer water outlet structure is protected, but the integrated water vector atomization core 10 of any layer is protected.

[0042] In one embodiment, the integrated water vector atomization core 10 of this application is made of light alloy material, such as aluminum alloy, magnesium alloy or titanium alloy. Further, in another embodiment, the integrated water vector atomization core 10 can also be zinc alloy, or ferrous metal.

[0043] As Figure 1 、 Figure 2 、 Figure 5 and Figure 6 shown, in one embodiment, the total length of the water distribution pipe 200 and the flange 300 is D, and a reinforcing block 400 is further arranged between any two adjacent water distribution pipes 200, and the length of the reinforcing block 400 is E, where 0mm < E ≤ D.

[0044] It should be noted that in order to enhance the structural strength between the water distribution pipes 200 and the seat body 100, a reinforcing block 400 is further provided between any two adjacent water distribution pipes 200. Since the water distribution pipes 200 extend from the outer side wall of the seat body 100, the reinforcing block 400 also extends from the outer side wall of the seat body 100. The length E of the reinforcing block 400 does not exceed the total length D of the water distribution pipe 200 and the flange 300. In one embodiment, the length E of the reinforcing block 400 is 0 mm, which means that there is no reinforcing block 400 between any two adjacent water distribution pipes 200 at this time. Further, in one embodiment, the length E of the reinforcing block 400 is equal to the length of the water distribution pipe 200, that is, the reinforcing block 400 only extends from the outer side wall of the seat body 100 to the connection position between the flange 300 and the water distribution pipe 200. Further, in one embodiment, the length E of the reinforcing block 400 is equal to the total length D of the water distribution pipe 200 and the flange 300. At this time, the reinforcing block 400 extends from the outer side wall of the seat body 100 to the end face of the flange 300. Further, the thickness of the reinforcing block 400 is not limited, and its thickness only needs to be greater than 0 mm. It should be noted that the reinforcing block 400, the water distribution pipe 200, and the seat body 100 are also integrally formed by casting, so as to ensure sufficient strength between the reinforcing block 400 and the water distribution pipe 200.

[0045] As Figure 1 shown, in one embodiment, a rounded corner portion 220 is provided at the connection position between the water distribution pipe 200 and the seat body 100 / the reinforcing block 400.

[0046] In this way, the connection position between the water distribution pipe 200 and the seat body 100 / the reinforcing block 400 is a smooth transition structure. On the one hand, when the casting mold is demolded, the integrated water vector atomization core 10 can be reliably and stably demolded from the casting mold; on the other hand, the structural strength between the water distribution pipe 200 and the seat body 100 / the reinforcing block 400 can be improved.

[0047] In one embodiment, the inner side wall of the axial cavity 110 and the outer side wall of the seat body 100 are both cylindrical surface structures. Therefore, the inner diameter of the axial cavity 110 remains the same in the direction from one end of the seat body 100 to the other end, and the outer diameter of the seat body 100 remains the same in the direction from the connection with the water distribution pipe 200 to both ends of the seat body 100.

[0048] Further, in another embodiment, in order to facilitate the demolding of the seat body 100, the inner diameter of the axial cavity 110 decreases in the direction from the parting surface to both ends of the seat body, and the outer diameter of the seat body 100 decreases in the direction from the connection with the water distribution pipe 200 to both ends of the seat body 100.

[0049] Specifically, the integrated water vector atomization core 10 of the present application is made by an integral casting process using a casting mold. To facilitate the demolding of the integrated water vector atomization core 10, for the axial cavity 110, any radial surface of the axial cavity 110 can be set as the parting surface according to actual needs, and then it decreases in the direction of both ends of the seat body 100 along this parting surface. In this way, it is convenient to withdraw the casting mold from the axial cavity 110. Further, for the outer side wall of the seat body 100, with the outer diameter of the seat body 100 as the parting surface at the connection position of the main body and the water distribution pipe 200, it decreases in the direction of both ends of the seat body 100. That is, the outer diameter of the middle part of the seat body 100 is relatively large, and the outer diameters of both ends are relatively small. In this way, the seat body 100 can be smoothly demolded from the casting mold. Further, each water distribution pipe 200 / flange 300 takes the plane that passes through its axis and can divide it into two parts along the axis of the seat body 100 as the parting surface. In this way, it is ensured that after the casting mold is opened, the integrated water vector atomization core 10 can be smoothly withdrawn from the mold.

[0050] As Figure 1 and Figure 2 shown, in one embodiment, at least one annular groove 310 is formed on the side surface of the flange 300 away from the water distribution pipe 200. Each annular groove 310 is coaxially distributed with each water outlet hole 210, and the diameter of the annular groove 310 is larger than the diameter of the water outlet hole 210.

[0051] It should be noted that an annular groove 310 coaxially distributed with the water outlet hole 210 is formed on the side surface of the flange 300 away from the water distribution pipe 200. This annular groove 310 is recessed inward. In this way, it is convenient to place a sealing ring in the annular groove 310 during the subsequent installation and use of the integrated water vector atomization core 10 for sealing with other components such as the nozzle. Each water outlet hole 210 corresponds to an annular groove 310, and the annular grooves 310 on the same flange 300 are independent and non - communicating with each other, so as to be able to install a sealing ring for each water outlet hole 210.

[0052] As Figure 1 shown, in one embodiment, a number of through - holes 320 are also formed on the flange 300. Each through - hole 320 is circumferentially distributed around the water outlet hole 210.

[0053] It should be noted that a plurality of through - holes 320 are drilled on each flange 300. Each through - hole 320 is circumferentially distributed around the water outlet hole 210. In this way, it is convenient to pass screws through the through - holes 320 to install and fix the nozzle on the flange 300 during the subsequent installation and use of the integrated water vector atomization core 10.

[0054] As Figure 2As shown, in one embodiment, a bevel surface 330 is provided on a side of the flange 300 close to the water distribution pipe 200, and the perpendicular distance between the bevel surface 330 and the axis of the seat body 100 increases in a direction away from the water distribution pipe 200.

[0055] It should be noted that the surface of the flange 300 is perpendicular to the axis of the water distribution pipe 200, and the diameter of the flange 300 is larger than the outer diameter of the water distribution pipe 200. Therefore, a right-angle structure will be formed between the side of the flange 300 close to the water distribution pipe 200 and the water distribution pipe 200. When the water distribution pipe 200 is in an upward or downward state relative to the seat body 100, in order to ensure that the integrated water vector atomization core 10 can be smoothly demolded, a bevel surface 330 is provided on the side of the flange 300 close to the water distribution pipe 200. The perpendicular distance between the bevel surface 330 and the axis of the seat body 100 gradually increases in the direction of the end of the seat body 100, so that an outward-expanded structure is formed between the bevel surface 330 of the flange 300 and the outer wall of the seat body 100, ensuring smooth demolding.

[0056] As Figure 2 、 Figure 4 、 Figures 7 to 11 shown, a method for manufacturing an integrated water vector atomization core includes the following steps:

[0057] Step S10, obtaining an integrally formed core blank 11 by casting. The core blank 11 includes a seat body 100, at least two water distribution pipes 200 and at least two flanges 300. An axial cavity 110 is provided at the axis of the seat body 100. One end of each water distribution pipe 200 is circumferentially and equally angularly arranged on the outer wall of the seat body 100, and each flange 300 is correspondingly arranged at the other end of each water distribution pipe 200. The included angle between the axis of each water distribution pipe 200 and the axis of the seat body 100 is α, where 0° < α < 180°;

[0058] Step S20, machining at least one water outlet hole 210 from the side of the flange 300 away from the water distribution pipe 200. Each water outlet hole 210 penetrates through the flange 300 and the water distribution pipe 200 to communicate with the axial cavity 110, obtaining the integrated water vector atomization core 10.

[0059] It should be noted that the integrated movement blank 11 is formed by casting with a casting mold. The base body 100 of the movement blank 11 has an axial cavity 110 distributed along the axial direction. Each water distribution pipe 200 is circumferentially and equally angularly distributed on the outer peripheral wall of the base body 100, and each flange 300 is respectively located at the end of each water distribution pipe 200 away from the base body 100. Further, by machining, drilling operations are performed on each water distribution pipe 200 and flange 300 of the movement blank 11, so that through holes 210 are formed on the flange 300 and the water distribution pipe 200, and the through holes 210 extend into the base body 100 to communicate with the axial cavity 110. It should be noted that each water distribution pipe 200 is formed with at least one through hole 210. For example, two independent through holes 210 can be drilled on the water distribution pipe 200, or three independent through holes 210 can be drilled, and so on. Further, it should be noted that the number of through holes 210 formed on each water distribution pipe 200 is the same, and the positions of the through holes 210 formed on the water distribution pipe 200 are also the same. In this way, it is ensured that the manufactured integrated water vector atomization movement 10 can maintain balance during actual rotation. It should be noted that the casting can be gravity casting, investment casting, die casting, and so on. In this application, die casting is used in combination with a die casting mold as an example for illustration, but it should not be construed as being limited to die casting. Further, in the manufacturing method of the integrated water vector atomization movement of this application, the material used to form the integrated water vector atomization movement is not limited to light metal materials, and can also be zinc alloy, iron-based metal, etc.

[0060] As Figure 7 and Figure 8 shown, in one embodiment, in step S10, both the water distribution pipe 200 and the flange 300 are solid structures. In step S20, at least one through hole 210 is formed on the solid flange 300 and the solid water distribution pipe 200 by a drilling machine.

[0061] It should be noted that in order to reduce the complexity of the casting mold, the casting mold is set to a non-core-pulling structure. In this way, the water distribution pipe 200 and the flange 300 are in a solid structure during the casting process. After the movement blank 11 is formed, a drilling machine is used to form through holes on the flange 300 and the water distribution pipe 200.

[0062] As Figure 9 and Figure 10 shown, in one embodiment, in step S10, at least one reserved hole 211 is formed on the flange 300, and the reserved hole 211 extends into the water distribution pipe 200.

[0063] It should be noted that, in this embodiment, by providing a core-pulling structure on the casting mold, when the movement blank 11 is cast and formed, the core-pulling structure forms a reserved hole 211 in the flange 300 and the water distribution pipe 200. Among them, the reserved hole 211 can penetrate the water distribution pipe 200 or not penetrate the water distribution pipe 200. To improve the stability of the casting mold, it is preferably that the reserved hole 211 is a structure that does not penetrate the water distribution pipe 200, that is, the reserved hole 211 is independent of the axial cavity 110. Thus, in step S20, a drilling machine processes the reserved hole 211 to a predetermined size and drills through the reserved hole 211 to form a water outlet hole 210 that penetrates the axial cavity 110. It should be noted that the advantage of the solution in this embodiment is that when the number of water distribution pipes 200 of a single movement blank 11 is large and the output of the movement blank 11 is large, forming the reserved hole 211 during the casting process can effectively reduce the machining amount of the movement blank 11.

[0064] The above-described embodiments merely represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. Among them, the installation / fixing / setting mentioned in the present invention can be understood to include, but not limited to, locking and fixing by using screws / screws and welding, unless otherwise specifically defined. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent should be subject to the appended claims.
