Abstract

This application provides a vector atomizing mechanism, including a central shaft, a rotating assembly, and a friction-reducing assembly. The central shaft has an internal channel for supplying cooling water. The rotating assembly is fitted onto the central shaft, forming an annular gap between the rotating assembly and the outer circumferential surface of the central shaft. The friction-reducing assembly is fixedly mounted on the rotating assembly and has a smooth contact surface that conforms to the outer circumferential surface of the central shaft. When the cooling water flows through the channel under pressure and drives the rotating assembly to rotate around the central shaft, sliding friction is generated between the smooth contact surface of the friction-reducing assembly and the outer circumferential surface of the central shaft. This structure reduces friction.

Description

Technical Field

[0001] This application relates to the field of cooling devices, and more particularly to a vector atomizing mechanism. Background Technology

[0002] In refrigeration engineering systems, HVAC fields, and various industrial heat exchange scenarios, to ensure efficient and stable system operation, the circulating hot water heated during the heat exchange process must be cooled before it can be reused. Currently, the specialized equipment that performs this function is collectively referred to as a cooling tower.

[0003] In high-heat-load scenarios such as large data centers, steel mills, or chemical plants, cooling towers need to rapidly process massive amounts of circulating hot water. To address this, increasing the rotational speed of the atomizing mechanism is proposed. However, conventional high-speed mechanical rotation relies on oil-lubricated bearings, such as ball bearings, which require grease filling to achieve rotation between stationary and rotating parts. But lubricating oil leakage in the cooling tower will directly contaminate the circulating cooling water.

[0004] Therefore, a vector atomizing mechanism that reduces friction is needed. Utility Model Content

[0005] In view of this, it is necessary to provide a vector atomizing mechanism that reduces friction to solve the above problems.

[0009] A friction-reducing component is fixedly installed on the rotating component, and the friction-reducing component has a smooth contact surface that fits against the outer peripheral surface of the central shaft;

[0010] When cooling water flows through the channel under pressure and drives the rotating assembly to rotate around the central axis, the smooth contact surface of the friction-reducing assembly forms a sliding friction force with the outer peripheral surface of the central axis.

[0027] In at least one embodiment of this application, the first friction-reducing component, the second friction-reducing component, and the third friction-reducing component are made of metal.

[0028] The aforementioned vector atomizing mechanism reduces friction during rotation by forming an annular gap between the rotating component and the outer circumferential surface of the central shaft, thereby reducing the contact area between the rotating component and the outer circumferential surface of the central shaft. Furthermore, by using a friction-reducing component with a smooth contact surface that fits against the outer circumferential surface of the central shaft, the low friction characteristics of the smooth contact surface are utilized to double reduce rotational resistance, enabling high-speed operation in an oil-free environment.

[0036] The embodiments of this application will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0037] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or may also have an intervening component. When a component is considered to be "placed" on another component, it can be directly placed on the other component or may also have an intervening component.

[0038] This application provides a vector atomizing mechanism, including a central shaft, a rotating assembly, and a friction-reducing assembly. The central shaft has a channel for conveying cooling water. The rotating assembly is sleeved on the central shaft, forming an annular gap between the rotating assembly and the outer circumferential surface of the central shaft. The friction-reducing assembly is fixedly mounted on the rotating assembly and has a smooth contact surface that conforms to the outer circumferential surface of the central shaft. When the cooling water flows through the channel under pressure and drives the rotating assembly to rotate around the central shaft, sliding friction is generated between the smooth contact surface of the friction-reducing assembly and the outer circumferential surface of the central shaft.

[0039] The aforementioned vector atomizing mechanism reduces friction during rotation by forming an annular gap between the rotating component and the outer circumferential surface of the central axis, thereby reducing the contact area between the rotating component and the outer circumferential surface of the central axis. Furthermore, by utilizing a friction-reducing component with a smooth contact surface that conforms to the outer circumferential surface of the central axis, the low friction characteristics of the smooth contact surface are doubled to reduce rotational resistance, achieving high-speed operation in an oil-free environment.

[0040] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0041] Please see Figures 1-6 This application provides a vector atomizing mechanism 100, including a central shaft 10, a rotating assembly 20, and a friction-reducing assembly 30. The central shaft 10 has a channel 11 for conveying cooling water. The rotating assembly 20 is sleeved on the central shaft 10, forming an annular gap 13 between the rotating assembly 20 and the outer peripheral surface 12 of the central shaft. The friction-reducing assembly 30 is fixedly mounted on the rotating assembly 20, and has a smooth contact surface 31 that conforms to the outer peripheral surface 12 of the central shaft. When cooling water flows through the channel 11 under pressure and drives the rotating assembly 20 to rotate around the central shaft 10, the smooth contact surface 31 of the friction-reducing assembly 30 forms sliding friction with the outer peripheral surface 12 of the central shaft.

[0042] Specifically, the central shaft 10 is a hollow cylindrical metal rod with a straight channel 11 running through its length. The channel 11 is used to introduce high-pressure cooling water from the device inlet into the internal mechanism, providing a kinetic energy source for subsequent spraying. The central shaft 10 not only serves as a fluid conduit but also as the fixed axis of the rotating component 20, achieving the dual functions of structural support and rotational guidance.

[0043] The rotating assembly 20 consists of at least a rotating body 21, a first fixing member 22, and a second fixing member 23. The rotating body 21 is a hollow sleeve structure with an outer diameter slightly larger than the central shaft 10. The first fixing member 22 and the second fixing member 23 are respectively installed at both ends of the hollow rotating body 21, and the central shaft 10 is located inside the rotating assembly 20. The rotating assembly 20 is installed on the outer periphery of the central shaft 10 by a fitting method, and an annular gap 13 is formed between the inner diameter of the rotating assembly 20 and the outer diameter of the central shaft 10. The annular gap 13 forms a sliding space to prevent wear caused by direct contact and to ensure that the rotating assembly 20 can be driven to rotate freely by water flow.

[0044] The friction-reducing component 30 is fixed to the inner wall or limiting component of the rotating component 20 by any of the following methods: interference fit, screw fixing, or slot assembly. As long as a fixed assembly is achieved, it is acceptable.

[0045] The friction-reducing component 30 can be a one-piece or segmented structure. In the segmented structure, the friction-reducing component 30 includes a first friction-reducing element 32 and a second friction-reducing element 33. Part of the friction-reducing component 30 rotates together with the rotating component 20 and generates sliding frictional contact with the central shaft 10.

[0046] The friction-reducing component 30 has a smooth contact surface 31 on its inner side that fits against the central shaft 10. The surface of the smooth contact surface 31 is a high-gloss machined surface to ensure low friction performance.

[0047] The smooth contact surface 31 is in close contact with the central shaft 10 in practice, but a micro gap is retained to form a water film lubrication layer.

[0048] The smooth contact surface 31 can be annular or segmented arc-shaped.

[0049] When the rotating component 20 drives the friction-reducing component 30 to rotate, the contact surface of the friction-reducing component 30 forms a sliding friction pair with the outer surface of the stationary central shaft 10. Friction is controlled through material selection, clearance control, and water film lubrication, ensuring that the friction is within a balanced range that supports rotation without causing wear. This method replaces traditional ball bearings, eliminating the need for lubrication. It also prevents grease leakage from contaminating the cooling water and supports the long-term operation of the entire rotating component.

[0050] In this application, the first fixing member 22 and the second fixing member 23 are respectively connected to the central shaft 10 with a clearance fit. The first fixing member 22 is located at the water-facing end of the rotating assembly 20 and is used to initially guide the cooling water jet. It also forms a sliding support through the first friction-reducing member 32 and the second friction-reducing member 33. The second fixing member 23 is located away from the cooling water inlet direction F1 and is used for tail limit and axial stability. The clearance between the first fixing member 22 and the second fixing member 23 and the central shaft 10 ensures flexible rotation and avoids jamming problems caused by thermal expansion or scale.

[0051] In one embodiment, the first friction-reducing component 32 is fixedly installed on the surface of the central shaft 10 as a static support, arranged along the cooling water inflow end. One side of it contacts the first fixing component 22 and forms a sliding contact surface, while the other side is fastened to the central shaft 10 by screws, adhesive, or press-fitting, and does not participate in rotation. Its outer surface can be metal, and its outer surface can be a smooth contact surface.

[0052] The second friction-reducing component 33 serves as a rotating friction pair. One side of it is in contact with the outer circumferential surface of the central shaft 10, allowing relative sliding, while the other side is fixedly connected to the first fixing component 22 or the rotating body 21. This structure allows the second friction-reducing component 33 to rotate synchronously with the rotating assembly 20, thereby forming a controllable low-friction rotating pair on the contact surface with the first friction-reducing component 32.

[0053] The above structure achieves a fixed and rotating separate design, which is different from the traditional integral sliding bushing design. It not only has less friction, but also allows for independent replacement of failed parts as needed, thus improving maintenance efficiency.

[0054] To further improve the overall structural stability of the movement, this embodiment also adds a third friction-reducing component 34 at the tail of the central axis 10. One side of this friction-reducing component connects the rotating body 21 and the second fixing component 23, while the other side forms a rotational fit with the outer circumferential surface of the tail end of the central axis 10. This friction-reducing component not only serves as an axial limiter at the rear end but also constitutes an additional sliding support surface, reducing the spindle runout that may be caused by uneven wear at the tail end.

[0055] The third friction-reducing component 34 is made of metal, achieving a smooth contact surface 31. It is assembled using injection molding or elastic nesting. This design further reduces the relative friction between the rotating assembly 20 and the central shaft 10, ensuring balance and stability during high-speed operation.

[0056] An annular rotating groove 321 is specially provided on the axial contact surface of the first friction-reducing member 32. The rotating groove 321 is an annular groove, which is used to accommodate the end face of the first fixing member 22, so that it forms a restricted sliding contact surface and provides a rotating pair structure.

[0057] To improve drive efficiency and accelerate rotation start-up response, multiple hollow sections 14 are provided on the side wall of the central shaft 10 near the sleeve portion 212 of the rotating assembly 20. The hollow sections 14 are multiple axial through holes that connect to the cooling water channel 11 inside the central shaft 10, allowing high-pressure cooling water to be laterally guided from the central shaft 10 into the interior of the rotating assembly 20.

[0058] The rotating body 21 of the rotating assembly 20 has multiple water guide ports 211, which are connected to the internal channel 11 of the central shaft 10 through a hollow portion 14. The water guide ports 211 can be directly connected to the subsequent spray bar 213 structure to guide high-pressure cooling water outward. The design angle and area of ​​the water guide ports 211 directly affect the rotational torque and spray particle size; a tangential water outlet structure is preferred in the design.

[0059] Multiple spray bars 213 are installed on the outside of the rotating body 21, and the spray bars 213 are connected to the water inlet 211. Each spray bar 213 has a slender hollow structure and is installed at a certain angle to the rotating body 21. It sprays water mist in the direction of rotation, forming a reaction force to drive the rotation.

[0060] To achieve a balanced rotational torque, multiple spray bars 213 are evenly arranged around the rotating body 21.

[0061] The nozzles mounted on the spray bar 213 are arranged tangentially to the rotation direction of the rotating assembly 20, forming a tangential flow guidance structure.

[0062] Under high pressure, cooling water is sprayed out through the inner channel 11 of the central shaft 10 to the end of the spray bar 213 or the water guide 211. The reaction force or tangential jet generated by the water flow drives the rotating component 20 to rotate. The rotating component 20 contacts the central shaft 10 through the sliding pair structure of the friction-reducing component 30, forming a rotating structure that supports and restricts friction, thereby achieving oil-free high-speed rotating atomization.

[0063] When the vector atomizing mechanism 100 is in operation, cooling water flows in through the internal channel 11 of the central shaft 10 and enters the rotating assembly 20 through the hollowed-out portion 14 on the side wall of the central shaft 10. The water flow is guided tangentially along the rotation direction into the spray bar 213, and then sprayed out at high speed from the nozzle at the end of the spray bar 213, driving the rotating assembly 20 to rotate at high speed around the central shaft 10. To achieve low-resistance rotation without lubrication, the mechanism is equipped with a multi-stage friction-reducing structure.

[0064] The multi-stage friction reduction structure includes a first friction-reducing component 32 fixed on the central shaft 10, a second friction-reducing component 33 connected to the first friction-reducing component 32, and the two forming an axial sliding pair. The second friction-reducing component 33 is located at the front of the rotating assembly 20, near the cooling water inlet direction F1, and the third friction-reducing component 34 is located at the rear of the rotating assembly 20, forming radial sliding pairs with the central shaft 10 respectively. All contact surfaces are smooth curved surfaces, and water-erosion-resistant low-friction materials such as PTFE or ceramics are used. The structure layout and material selection reduce friction, enabling the rotating assembly 20 to rotate stably, at high speed, and with low consumption for a long time in a water environment.

[0065] Therefore, the vector atomizing mechanism 100 provided above reduces the contact area between the rotating component 20 and the outer peripheral surface 12 of the central shaft by forming an annular gap 13, thereby reducing the friction generated during rotation; and by using the friction-reducing component 30 with a smooth contact surface 31 that fits against the outer peripheral surface 12 of the central shaft, the low friction characteristics of the smooth contact surface 31 are utilized to doubly reduce rotational resistance, thereby achieving high-speed operation in an oil-free environment.

[0066] The above description is merely an embodiment of this application. It should be noted that those skilled in the art can make improvements without departing from the inventive concept of this application, but these improvements all fall within the protection scope of this application.
