Description

Technology Field

[0001] The present invention relates to the technical field of manufacturing cooling devices, and in particular to an integrated water vector spray core and a method for manufacturing the same. Background Technology

[0002] A water vector spray core is a component mounted on a cooling tower. A Chinese patent document with publication number CN117245070A discloses a method for manufacturing a water vector spray core, wherein the manufacturing method involves using a method combining aluminum alloy casting and welding to manufacture the water vector spray core by welding a water pipe having a flange to a main body base formed by aluminum alloy casting. A Chinese patent document with publication number CN117464323A discloses a water vector core and a method for manufacturing the same, wherein the manufacturing method involves manufacturing the water vector core by surrounding several side perimeter members and then welding.

[0003] However, in existing technologies, water vector spray cores are formed into a single integrated unit by welding multiple parts. Since having many parts implies a large number of weld beads and narrow spaces between adjacent parts, it is difficult for the welding torch to enter the parts without obstruction and weld, resulting in very low welding efficiency and increased difficulty in mass production. Furthermore, because the core must be used under relatively high water pressure (e.g., ≥0.1 MPa), there are high quality requirements for the weld beads. As the number of weld beads increases, the risk of incomplete sealing and leakage increases, leading to a higher risk of subsequent maintenance. Finally, having many parts and a large number of weld beads increases the risk of deformation in the overall structure. Accordingly, to solve the aforementioned problems, an integrated water vector spray core and a method for manufacturing the same are proposed according to the present application. The problem to be solved

[0004] The objective of the present invention is to overcome the disadvantages of the prior art and to provide an integrated water vector spray core with good mass producibility, low maintenance risk, high strength, and high precision, and a method for manufacturing the same, which can significantly reduce the number of parts through integrated molding. means of solving the problem

The angle between the axis of each branch water pipe and the axis of the base body is α, and 0° < α < 180°. A flange plate is further integrally formed at one end of the branch water pipe moving away from the base body. Each flange plate is provided with at least one discharge hole, and each discharge hole penetrates the branch water pipe and communicates with the axial cavity.

[0009] Optionally, at least one annular groove is provided on one side of the flange plate extending away from the branch pipe, each annular groove is distributed coaxially with the outlet hole, and the diameter of the annular groove is larger than the diameter of the outlet hole.

[0010] Optionally, the flange plate is further provided with several through holes, and each of the through holes surrounds the outlet hole and is distributed in a circumferential direction.

[0011] Optionally, an inclined surface is installed on one side of the flange plate near the branch pipe, and the vertical distance between the inclined surface and the axis of the base body increases as it moves away from the branch pipe.

[0012] Optionally, the integrated water vector spray core is made of a lightweight alloy material.

[0013] A method for manufacturing an integrated water vector spray core includes the following steps:

[0014] Step S10, a core blank formed integrally through a casting method is obtained, wherein the core blank comprises a base body, at least two branch pipes, and at least two flange plates, wherein an axial cavity is provided in the axis of the base body, and one end of each branch pipe is installed on the outer wall of the base body at an equal angle along the circumference, and each flange plate is installed in a one-to-one correspondence with the other end of each branch pipe, and the angle between the axis of each branch pipe and the axis of the base body is α, and 0° < α < 180°; and

[0015] In step S20, at least one outlet hole is formed by machining, through a machining method, on one side of the flange plate away from the branch water pipe, so as to penetrate the flange plate and the branch water pipe respectively and communicate with the axial cavity, thereby obtaining an integrated water vector spray core.

[0016] Optionally, in step (S10), the branch pipe and the flange plate are both solid structures.

[0017] A method for manufacturing an integrated water vector spray core, wherein, optionally, in step (S10), at least one preliminary hole is provided in the flange plate, and the preliminary hole extends into the branch water pipe. Effects of the invention

Finally, the integral water vector spray core according to the present application can be cast using a single set of casting molds, which significantly reduces the number of parts and eliminates the need for a large volume of welding processes, making mass production easier.

For example, they may be fixed connections or detachable connections, mechanical connections or electrical connections, direct interconnections or indirect connections through an intermediate medium, or communication within two elements or an interactive relationship between two elements. A person skilled in the art can understand the specific meaning of the terms described above in embodiments of the present invention according to specific circumstances.

[0025] As illustrated in FIGS. 1 to 4, the integrated water vector spray core (10) includes a base body (100), an axial cavity (110) is provided at the axis of the base body (100), at least two branch water pipes (200) are integrally formed on the outer wall of the base body (100) and distributed at equal angles along the circumference, the angle between the axis of each branch water pipe (200) and the axis of the base body (100) is α, 0° < α < 180°, and a flange plate (300) is further integrally formed at one end of the branch water pipe (200) moving away from the base body (100), and at least one discharge hole (210) is provided in each flange plate (300), and each discharge hole (210) penetrates the branch water pipe (200) and communicates with the axial cavity (110).

[0026] It should be explained that the integrated water vector spray core (10) according to the present application comprises a base body (100), at least two branch pipes (200), and a flange plate (300) formed integrally. Here, a through-type axial cavity (110) is provided in the axial direction of the base body (100). In this way, the casting core is ensured to be smoothly withdrawn from inside the axial cavity (110) after the core casting is completed. Furthermore, each branch pipe (200) is distributed at an equal angle along the circumference of the outer wall of the base body (100), and the number of branch pipes (200) is at least two, thereby ensuring that the core maintains balance during rotation. Furthermore, for example, the branch pipes (200) may be installed in the number of 10, 16, 18, or 24, etc. Each branch pipe (200) has an angle between the axis of the branch pipe (200) and the axis of the axial cavity (110) that is greater than 0° and less than 180°. Specifically, for convenience of explanation, the base body (100) is positioned vertically, so that when α=90°, the branch pipe (200) extends outward along the radial direction of the base body (100) to form a horizontal state, when 0°<α<90°, the branch pipe (200) forms an upward inclined state relative to the base body (100), and when 90°<α<180°, the branch pipe (200) forms a downward inclined state relative to the base body (100). Furthermore, a flange plate (300) is formed at one end of each branch pipe (200) that moves away from the base body (100). Each flange plate (300) is provided with at least one discharge hole (210) along the axial direction, and each discharge hole (210) is connected to an axial cavity (110). Here, the positions of each discharge hole (210) of each flange plate (300) coincide with each other, thereby ensuring that the integrated water vector spray core (10) can maintain balance during rotation when in use.As such, compared to a core formed by welding multiple parts through a welding process in existing technology, the core according to the present application is an integral core formed by a casting process, which avoids the risk of incomplete sealing and leakage caused by welding, thus lowering the probability of subsequent maintenance and ensuring reliable use. Furthermore, since the fact that welding is not required means that the entire structure of the core does not undergo deformation due to welding, the manufacturing precision is higher. Finally, while the existing core requires multiple parts to be formed through mass welding, the integral water vector spray core (10) according to the present application can be cast using a single set of casting molds, thereby eliminating the welding process and facilitating mass production.

[0027] As illustrated in FIGS. 1 and 3, in one embodiment, each flange plate (300) is provided with one water outlet hole (210), and the positions of the water outlet holes (210) of each flange plate (300) coincide, thereby forming an integrated water vector spray core (10) as a single-layer water outlet structure. Furthermore, in another embodiment, each flange plate (300) is provided with two water outlet holes (210), and the two water outlet holes (210) are spaced apart along the axial direction of the axial cavity (110), and the positions of each water outlet hole (210) of each flange plate (300) coincide, thereby forming an integrated water vector spray core (10) as a double-layer water outlet structure. Furthermore, in another embodiment, each flange plate (300) is provided with three water outlet holes (210), the three water outlet holes (210) are spaced apart along the axial direction of the axial cavity (110), and the positions of each water outlet hole (210) of each flange plate (300) coincide, thereby forming an integrated water vector spray core (10) into a triple-layer water outlet structure. In this way, when there are multiple water outlet holes (210) provided in any flange plate (300), the integrated water vector spray core (10) is formed with a corresponding layered water outlet structure. For convenience of understanding the technology, the present application presents examples of a single-layer water outlet structure, a double-layer water outlet structure, and a triple-layer water outlet structure, but it should not be understood that only the integrated water vector spray core (10) of the single-layer water outlet structure, double-layer water outlet structure, and triple-layer water outlet structure is protected, but rather any layered integrated water vector spray core (10) is protected.

[0028] In one embodiment, the integral water vector spray core (10) according to the present application is made of a lightweight alloy material, for example, an aluminum alloy, a magnesium alloy, or a titanium alloy. Furthermore, in another embodiment, the integral water vector spray core (10) may be a zinc alloy or an iron-based metal.

[0029] As illustrated in FIGS. 1, 2, 5 and 6, in one embodiment, the total length of the branch pipe (200) and the flange plate (300) is D, and a reinforcing block (400) is further installed between any two adjacent branch pipes (200), the length of the reinforcing block (400) is E, and 0mm < E ≤ D.

[0030] It must be explained that, in order to strengthen the structural strength between the branch pipe (200) and the base body (100), a reinforcing block (400) is further installed between any two adjacent branch pipes (200). Since the branch pipe (200) extends outward from the outer wall of the base body (100), the reinforcing block (400) also extends outward from the outer wall of the base body (100). Here, the length (E) of the reinforcing block (400) does not exceed the total length (D) of the branch pipe (200) and the flange plate (300). In one embodiment, the length (E) of the reinforcing block (400) is 0 mm. This means that there is no reinforcing block (400) between any two adjacent branch pipes (200) at this time. Furthermore, in one embodiment, the length (E) of the reinforcing block (400) is equal to the length of the branch pipe (200), that is, the reinforcing block (400) extends only from the outer wall of the base body (100) to the connection point between the flange plate (300) and the branch pipe (200). Furthermore, in one embodiment, the length (E) of the reinforcing block (400) is equal to the total length (D) of the branch pipe (200) and the flange plate (300), where the reinforcing block (400) extends from the outer wall of the base body (100) to the end surface of the flange plate (300). Furthermore, the thickness of the reinforcing block (400) is not limited, and it only needs to be greater than 0 mm. It should be noted that the reinforcing block (400), the branch pipe (200), and the base body (100) are also integrally cast and molded through a casting method, and that sufficient strength is secured between the reinforcing block (400) and the branch pipe (200) in this way.

[0031] As shown in FIG. 1, in one embodiment, a round portion (220) is installed at the connection location between the branch pipe (200) and the base body (100) / reinforcement block (400).

[0032] In this way, the connection position between the branch pipe (200) and the base body (100) / reinforcement block (400) can be made into a smooth transition structure, and the integral water vector spray core (10) can be reliably and stably removed from the casting mold when the casting mold is demolded, while the structural strength between the branch pipe (200) and the base body (100) / reinforcement block (400) can be improved.

[0033] In one embodiment, since the inner wall of the axial cavity (110) and the outer wall of the base body (100) are both cylindrical surfaces, the inner diameter of the axial cavity (110) is maintained constant from one end of the base body (100) to the other end, and the outer diameter of the base body (100) is maintained constant from the connection point with the branch pipe (200) to both ends of the base body (100).

[0034] Furthermore, in another embodiment, for the convenience of demolding the base body (100), the inner diameter of the axial cavity (110) decreases as it goes toward both ends of the base body from the parting surface, and the outer diameter of the base body (100) decreases as it goes toward both ends of the base body (100) at the connection position with the branch water pipe (200).

[0035] Specifically, the integrated water vector spray core (10) according to the present application is manufactured by an integrated casting process using a casting mold, and for the convenience of demolding the integrated water vector spray core (10), in the case of the axial cavity (110), an arbitrary radial plane of the axial cavity (110) is set as a parting plane according to actual needs, and then the diameter can be reduced as it goes toward both ends of the base body (100) along said parting plane, so that the casting mold can be conveniently withdrawn from inside the axial cavity (110). Furthermore, in the case of the outer wall of the base body (100), the outer diameter of the base body (100) is reduced as it goes toward both ends of the base body (100) by setting the connection position between the main body and the branch water pipe (200) as a parting plane. This corresponds to the outer diameter of the central part of the base body (100) being relatively large and the outer diameters of both ends being relatively small, thereby allowing the base body (100) to be smoothly ejected when demolded from inside the casting mold. Furthermore, each branch water pipe (200) / flange plate (300) passes through its axis and has a plane that can divide it into two parts along the axial direction of the base body (100) as a parting surface, thereby ensuring that the integrated water vector spray core (10) can be smoothly ejected from inside the mold after the casting mold is opened.

[0036] As illustrated in FIGS. 1 and 2, in one embodiment, at least one annular groove (310) is provided on one side of a flange plate (300) away from a branch pipe (200), each annular groove (310) is distributed coaxially 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).

[0037] It must be explained that an annular groove (310) distributed coaxially with the water outlet hole (210) is machined and formed on one side of the flange plate (300) away from the branch water pipe (200), and the annular groove (310) is recessed inward, and thus, when subsequently mounting and using the integrated water vector spray core (10), a sealing ring can be seated inside the annular groove (310) to seal it with other parts such as a spray nozzle, which is convenient. Each water outlet hole (210) corresponds to one annular groove (310), and the annular grooves (310) of the same flange plate (300) are independent of each other and do not communicate, so that one sealing ring can be mounted in each water outlet hole (210).

[0038] As illustrated in FIG. 1, in one embodiment, the flange plate (300) is further provided with several through holes (320), each through hole (320) surrounds the water outlet hole (210) and is distributed along the circumference.

[0039] It should be explained that each flange plate (300) has a plurality of through holes (320) drilled in it, and each through hole (320) is distributed around the discharge hole (210). In this way, when subsequently mounting and using the integrated water vector spray core (10), it is convenient to allow a screw to pass through the through hole (320) to install and fix the spray nozzle to the flange plate (300).

[0040] As illustrated in FIG. 2, in one embodiment, an inclined surface (330) is installed on one side of the flange plate (300) near the branch pipe (200), and the vertical distance between the inclined surface (330) and the axis of the base body (100) increases as it moves away from the branch pipe (200).

[0041] The surface of the flange plate (300) and the axis of the branch water pipe (200) are perpendicular to each other, and the diameter of the flange plate (300) is larger than the outer diameter of the branch water pipe (200), so that one side of the flange plate (300) near the branch water pipe (200) can form a right-angle structure between it and the branch water pipe (200), and in order to ensure that the integrated water vector spray core (10) can be smoothly demolded when the branch water pipe (200) is in an upward or downward inclined state relative to the base body (100), an inclined surface (330) is installed on one side of the flange plate (300) near the branch water pipe (200), and the vertical distance between the inclined surface (330) and the axis of the base body (100) increases as it goes toward the end direction of the base body (100), so that the inclined surface (330) of the flange plate (300) and the base It must be explained that by forming a structure that extends outward between the outer walls of the body (100), it is ensured that the mold can be smoothly demolded.

[0042] As illustrated in FIGS. 2, 4, and FIGS. 7 to 11, a method for manufacturing an integrated water vector spray core is,

[0043] A step (S10) of obtaining a core blank (11) integrally formed through a casting method—the core blank (11) comprises a base body (100), at least two branch pipes (200), and at least two flange plates (300), wherein an axial cavity (110) is provided at the axis of the base body (100), and one end of each branch pipe (200) is installed on the outer wall of the base body (100) at an equal angle along the circumference, and each flange plate (300) is installed in a one-to-one correspondence with the other end of each branch pipe (200), and the angle between the axis of each branch pipe (200) and the axis of the base body (100) is α, and 0° < α < 180°—; and

[0044] The method includes the step (S20) of forming at least one outlet hole (210) through a machining method on one side of a flange plate (300) that is away from a branch pipe (200), penetrating the flange plate (300) and the branch pipe (200) respectively to communicate with an axial cavity (110), and obtaining an integrated water vector spray core (10).

[0045] It must be explained that the core blank (11) is cast and formed using a casting mold. Here, the base body (100) of the core blank (11) is provided with an axial cavity (110) distributed along the axial direction, each branch pipe (200) is distributed at equal angles along the circumference of the outer wall of the base body (100), and each flange plate (300) is located at one end of each branch pipe (200) that is away from the base body (100). Furthermore, a drilling operation is performed on each branch pipe (200) and flange plate (300) of the core blank (11) through a machining method to form a through-type discharge hole (210) in the flange plate (300) and the branch pipe (200), and the discharge hole (210) extends into the interior of the base body (100) and communicates with the axial cavity (110). It should be noted that at least one discharge hole (210) is provided in each branch water pipe (200), and for example, two independent discharge holes (210) can be drilled in the branch water pipe (200), or three independent discharge holes (210) can be drilled. Furthermore, the number of discharge holes (210) formed in each branch water pipe (200) is equal to each other, and the positions of each discharge hole (210) formed in the branch water pipe (200) are also equal to each other. It should be noted that the integral water vector spray core (10) produced in this way is secured to maintain balance during actual rotation. It should be noted that various casting methods are possible, such as gravity casting, precision casting, and die casting. In this application, a combination of a die casting method and a die casting mold is described as an example, but it should not be understood as being limited to the die casting method. Furthermore, in the method for manufacturing an integrated water vector spray core according to the present application, the material for forming the integrated water vector spray core is not limited to a lightweight metal material and may also be a zinc alloy, an iron-based metal, etc.

[0046] As illustrated in FIGS. 7 and 8, in one embodiment, in step (S10), the branch pipe (200) and the flange plate (300) are both solid structures. In step (S20), at least one outlet hole (210) is formed in the solid flange plate (300) and the solid branch pipe (200) through a drilling machine.

[0047] To reduce the complexity of the casting mold, it must be explained that the casting mold is configured to have a structure without a core extraction structure, and that the branch pipe (200) and the flange plate (300) form a solid structure during the casting process. After the core blank (11) is formed, a drilling machine is used to form a water outlet hole in the flange plate (300) and the branch pipe (200).

[0048] As illustrated in FIGS. 9 and 10, in one embodiment, at step (S10), at least one spare hole (211) is provided in the flange plate (300), and the spare hole (211) extends into the branch pipe (200).

[0049] In this embodiment, it must be explained that by providing a core extraction structure in the casting mold, a preliminary hole (211) is formed inside the flange plate (300) and branch pipe (200) by the extraction structure when the core blank (11) is cast. Here, the preliminary hole (211) may penetrate the branch pipe (200) or may not penetrate the branch pipe (200). To improve the stability of the casting mold, preferably, the preliminary hole (211) is structured so as not to penetrate the branch pipe (200), that is, the preliminary hole (211) and the axial cavity (110) are independent of each other. Thus, in step (S20), the preliminary hole (211) is machined to a predetermined size using a drilling machine and the preliminary hole (211) is penetrated to form an outlet hole (210) that penetrates the axial cavity (110). It should be noted that the advantage of the method according to the present embodiment is that when the number of branch pipes (200) of a single core blank (11) is large and the production volume of the core blank (11) is large, the amount of machining of the core blank (11) can be effectively reduced by forming a pre-hole (211) during the casting process.

[0050] The embodiments described above represent only a few embodiments of the present invention. Although the description is relatively specific and detailed, it should not be understood as a limitation on the scope of the patent. Unless otherwise specifically defined, the mounting / fixing / installation mentioned in the present invention may be understood to include, but not be limited to, fastening using screws / bolts and welding. Those skilled in the art should be aware that various modifications and improvements can be made without departing from the spirit of the present invention, and that all of these fall within the scope of protection of the present invention. Accordingly, the scope of protection of the patent for the present invention should be based on the appended claims. Explanation of the symbols
