Description

[0002] In an air-conditioning heat pump system, the pipeline is a key part for connecting each core component, transporting refrigerant, and maintaining the system pressure and flow rate.

Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0048] This embodiment provides a pipeline vibration damping device for an air-conditioning heat pump system, which can extend the service life; save installation space and cost, and improve the compactness of the layout of the air-conditioning heat pump system.

[0049] As Figure 1 、 Figure 2 and Figure 8 shown, the pipeline vibration damping device for the air-conditioning heat pump system mainly includes a pipe body 100 and a vibration damping assembly. Among them, the pipe body 100 includes a body portion 110, two limiting portions 120 and two flared portions 130. The two limiting portions 120 are respectively arranged at both ends of the body portion 110, and each flared portion 130 is connected to a limiting portion 120; and the flared portion 130 is communicated with the body portion 110 through the limiting portion 120; the flared portion 130 is configured to be communicated with the pipeline 600 of the air-conditioning heat pump system. The vibration damping assembly is arranged in the body portion 110 and the limiting portion 120, and one end of the vibration damping assembly is located in one of the limiting portions 120, and the other end is located in the other limiting portion 120; there are activity gaps between both ends of the vibration damping assembly and the inner wall of the limiting portion 120, and the activity gaps are configured to enable the vibration damping assembly to generate an adaptive swinging motion under the excitation of vibration; the limiting portion 120 is configured to limit the vibration damping assembly.

[0050] Based on the above design, in this embodiment, by connecting the flared portion 130 of the pipe body 100 to the air-conditioning heat pump system pipeline 600, when mechanical vibration or flow vibration occurs in the air-conditioning heat pump system pipeline 600, the energy generated by the vibration can be transmitted to the vibration damping component. Since there are movable gaps between both ends of the vibration damping component and the inner wall of the limiting portion 120, at this time, the vibration damping component can generate an adaptive swinging motion under the excitation of the vibration. Through the swinging of the vibration damping component, this part of the vibration energy is absorbed, dissipated, inertia-canceled, and dynamically tuned to transfer, so as to achieve the purpose of energy conversion and dynamic balance, and further achieve the vibration damping effect. Thus, there is no need for the vibration damping rubber pad in the prior art, solving the problem that rubber is prone to aging and failure in high-temperature, ultraviolet, and oil-pollution environments, and extending the service life of the vibration damping device for the air-conditioning heat pump system pipeline. At the same time, there is no need to set the large-arc elbow in the prior art, saving the installation space, improving the compactness of the layout of the air-conditioning heat pump system, saving costs, and reducing the installation difficulty.

[0051] In this embodiment, the diameter of the flared portion 130 is larger than the diameter of the main body portion 110. The limiting portion 120 is connected between the flared portion 130 and the main body portion 110, and the flared portion 130 and the main body portion 110 form a stepped structure, which not only provides a vibration space for the vibration damping component, but also can limit the vibration damping component, reducing the phenomenon of offset and dislocation of the vibration damping component.

[0052] As Figures 1-6 shown, in this embodiment, the vibration damping component includes a counterweight shuttle 200, two elastic members 300, and two limiting members 400; one end of one elastic member 300 is respectively connected to one end of the counterweight shuttle 200 and one of the limiting members 400, and the two ends of the other elastic member 300 are respectively connected to the other end of the counterweight shuttle 200 and the other limiting member 400. The two limiting members 400 are respectively arranged in the limiting portion 120, and the limiting portion 120 is used to limit the limiting members 400.

[0053] When the air-conditioning heat pump system pipeline 600 generates vibration, the vibration is transmitted to the vibration damping component through the pipe body 100. The counterweight shuttle 200 swings under the action of the elastic member 300. The elastic force of the elastic member 300 can buffer and absorb the vibration energy. At the same time, the mass of the counterweight shuttle 200 can generate an inertial force, which is opposite to the vibration direction, thus achieving the vibration damping effect. The two limiting members 400 are respectively arranged in the limiting portion 120, and the limiting portion 120 limits the limiting members 400, thereby restricting the movement range of the counterweight shuttle 200 and the elastic member 300, preventing them from detaching from the pipe body 100, ensuring the stability and reliability of the vibration damping component, and further improving the vibration damping effect.

[0054] Furthermore, as Figure 1 、 Figure 2 and Figure 4As shown, the counterweight shuttle 200 includes a shuttle body 210. First internal threaded holes 220 are provided at both ends of the shuttle body 210, and one end of the elastic member 300 is threadedly connected to the first internal threaded hole 220. Optionally, the shuttle body 210 is in an olive shape. The olive-shaped shuttle body 210 has a streamlined structure, can swing freely within the pipe body 100, and reduce the resistance to fluid flow. At the same time, the internal fluid will also form an air flow barrier on the surface of the counterweight shuttle 200 to prevent the counterweight shuttle 200 from swinging excessively and hitting the inner wall of the pipe body 100 during use, thereby avoiding the generation of secondary vibration and further improving the vibration damping effect.

[0055] In addition, the first internal threaded holes 220 at both ends of the counterweight shuttle 200 facilitate the connection with the elastic member 300, ensuring the firmness and stability of the connection.

[0056] Exemplarily, in this embodiment, the counterweight shuttle 200 is processed from a metal material with a relatively high density. For example, it can be processed from stainless steel material, and its shape is a component with pointed ends, slightly thicker in the middle, and a smooth surface.

[0057] As Figure 1 、 Figure 2 and Figure 5 As shown, the elastic member 300 in this embodiment includes a spring body 310 and two straight sections 320. The two straight sections 320 are respectively connected to the opposite ends of the spring body 310. External threads 330 are provided on the straight sections 320. One of the straight sections 320 is connected to the limiting member 400, and the other straight section 320 is threadedly connected to the first internal threaded hole 220 of the shuttle body 210. By means of threaded connection, the installation and disassembly of the elastic member 300 are convenient, facilitating the replacement and maintenance of the elastic member 300, and ensuring the long-term effective operation of the vibration damping component.

[0058] As Figure 1 、 Figure 2 and Figure 6 As shown, in this embodiment, the limiting member 400 includes a limiting body 410 and a support frame 420. The support frame 420 is located inside the limiting body 410 and is connected to the inner wall of the limiting body 410. The limiting body 410 is located in the limiting portion 120. Such a design enables the limiting member 400 not only to limit the elastic member 300, but also to enhance its own structural strength through the support frame 420, ensuring the stable limitation of the excessive displacement of the elastic member 300 in a vibration environment, thereby improving the reliability of the entire vibration damping component. For example, during the operation of an air-conditioning heat pump system, the pipeline will generate multi-directional vibration impacts. The combination of the limiting body 410 and the support frame 420 can effectively prevent the elastic member 300 from shifting or twisting due to external forces, ensuring that the vibration damping component continuously exerts its vibration damping effect.

[0059] The support frame 420 is provided with a second internal thread hole 430 which is coaxially arranged with the limiting body 410. The second internal thread hole 430 is used for threadedly connecting with one of the straight sections 320 of the elastic member 300. This coaxial connection method ensures uniform force transmission and avoids premature failure of the elastic member 300 due to uneven force caused by eccentric connection. When vibration is transmitted to the elastic member 300, the elastic member 300 can uniformly transmit the received vibration energy to the limiting member 400 and disperse it to the pipe body 100 through the limiting member 400, effectively improving the vibration damping efficiency and prolonging the service life of the vibration damping assembly. In addition, through the threaded connection method, the installation and disassembly of the elastic member 300 and the limiting body 410 are convenient, facilitating the replacement and maintenance of the elastic member 300 and the limiting body 410, and ensuring the long-term effective operation of the vibration damping assembly.

[0060] Furthermore, the cross-sections of both the limiting body 410 and the limiting portion 120 are conical, and the limiting body 410 is adapted to the limiting portion 120. The conical limiting body 410 and the limiting portion 120 can be closely fitted to ensure the stability of the limiting member 400 in the limiting portion 120, preventing the limiting member 400 from shifting or loosening during vibration, thereby ensuring the limiting effect of the vibration damping assembly.

[0061] Specifically, the cross-sections of both the limiting body 410 and the limiting portion 120 are conical and adapted to each other, enabling the limiting body 410 to be closely embedded in the limiting portion 120. During vibration, the contact area between the conical limiting body 410 and the limiting portion 120 increases, and the friction force also increases, thereby more effectively restricting the axial and radial movement of the limiting member 400 and ensuring the stable position of the vibration damping assembly within the pipe body 100. For example, when the pipeline undergoes axial vibration, the close fit between the conical limiting body 410 and the limiting portion 120 can prevent the limiting member 400 from axially moving, thereby avoiding damage to the elastic member 300 due to excessive stretching or compression and ensuring the normal operation of the vibration damping assembly.

[0062] In addition, the conical structure has the functions of automatic guiding and centering. During the installation process, the limiting body 410 can be smoothly introduced into the limiting portion 120 and automatically adjust its position to be coaxial with the limiting portion 120. This not only facilitates the assembly of the vibration damping assembly, improves production efficiency, but also ensures the correct installation position of the vibration damping assembly within the pipe body 100, guarantees the consistency of its vibration damping performance, and reduces performance differences caused by installation errors.

[0063] In some alternative embodiments, a first through-hole 440 is formed between the inner wall of the support frame 420 and the limiting body 410, and / or a second through-hole (not shown in the figure) is provided on the support frame 420. Both the first through-hole 440 and the second through-hole are configured to allow fluid to flow through. In the air-conditioning heat pump system pipeline 600, fluids such as refrigerant need to flow smoothly inside the pipeline to ensure the heat exchange efficiency of the system. By providing the first through-hole 440 and / or the second through-hole, the obstruction of the limiting member 400 to fluid flow is reduced, the flow resistance of the fluid inside the pipeline is lowered, thereby improving the operating efficiency of the entire air-conditioning heat pump system and reducing energy loss. For example, when the air-conditioning heat pump system is operating, the fluid can flow smoothly through the limiting member 400 via the first through-hole 440 and the second through-hole, avoiding local fluid eddies and pressure losses caused by the obstruction of the limiting member 400.

[0064] In addition, providing the second through-hole on the support frame 420 can reduce the weight of the limiting member 400, which is particularly important for large air-conditioning heat pump systems that require a large number of vibration damping devices to be arranged. Reducing the weight not only facilitates installation and transportation but also lowers the requirements for the pipeline support structure. At the same time, by reasonably designing the shape and position of the second through-hole, lightweighting can be achieved on the premise that the limiting member 400 has sufficient strength, enabling it to improve the economy and operating stability of the entire system without affecting the vibration damping effect.

[0065] As Figure 1 、 Figure 2 and Figure 7 shown, the vibration damping device for the air-conditioning heat pump system pipeline in this embodiment further includes a fixing member 500. The end of the straight section 320 passes through the second internal thread hole 430, the fixing member 500 is provided on the straight section 320, and the fixing member 500 is located on the side of the limiting body 410 away from the elastic member 300. Such a design can further fix the connection between the elastic member 300 and the limiting member 400. Specifically, during vibration, the elastic member 300 is prone to loosening under alternating stress, while the setting of the fixing member 500 can effectively prevent the axial displacement of the elastic member 300, ensuring that the connection between the elastic member 300 and the limiting member 400 remains tight at all times, enhancing the reliability of the vibration damping assembly in a vibrating environment and avoiding a reduction or even failure of the vibration damping effect due to loose connection.

[0066] In addition, when the air-conditioning heat pump system pipeline 600 is subjected to a large vibration impact, the fixing member 500 can also disperse and buffer this part of the impact force, reducing the stress concentration borne by the elastic member 300 and the limiting member 400, thereby improving the structural strength of the entire vibration damping assembly, extending its service life, and reducing the maintenance and replacement frequency.

[0067] Specifically, the fixing member 500 includes a retaining ring body 510, a slot 520, a center hole 530 and a tool hole 540. The slot 520, the center hole 530 and the tool hole 540 are all arranged on the retaining ring body 510 and penetrate the opposite sides of the retaining ring body 510; the center hole 530 is interference fit with the straight section 320. The center hole 530 is coaxially arranged with the retaining ring body 510, and the diameter of the center hole 530 is smaller than the diameter of the straight section 320, so that the center hole 530 clamps the straight section 320. This interference fit design can generate a large friction force, effectively prevent the axial movement and rotation of the straight section 320 during use, ensure that the connection between the elastic member 300 and the limit member 400 is firm and reliable, and provide a strong guarantee for the stable operation of the vibration reduction assembly.

[0068] One end of the slot 520 is connected to the center hole 530, and the other end of the slot 520 passes through the peripheral side wall of the retaining ring body 510. The width of the slot 520 is smaller than the diameter of the center hole 530. Two tool holes 540 are provided, and the two tool holes 540 are respectively located on both sides of the slot 520.

[0069] The design of the slot 520 and the tool hole 540 makes it easier to install and remove the fixing member 500. During installation, the center hole 530 can be inserted into the straight section 320 by inserting a tool into the tool hole 540 and opening the slot 520 at a certain angle, and then the slot 520 can be loosened, and the center hole 530 can be tightly clamped on the straight section 320; during removal, the fixing member 500 can be easily removed by inserting a tool into the tool hole 540 again and opening the slot 520. This design does not require complicated tools and processes, and can quickly complete the installation and removal operations without damaging the fixing member 500 and the elastic member 300, thereby improving the efficiency of on-site installation and maintenance.

[0070] There are two tool holes 540, which are respectively located on both sides of the slot 520, making the structure of the entire fixing member 500 more symmetrical. This symmetrical design helps to balance the force of the fixing member 500 during use, avoid deformation or damage caused by uneven force, and further improve the stability and reliability of the fixing member 500.

[0071] The width of the groove 520 is smaller than the diameter of the center hole 530, so that the center hole 530 has a certain elastic deformation space when clamping the straight section 320, and can adapt to the straight sections 320 of different diameters, thereby increasing the versatility and flexibility of the fixing part 500. The operator can select the appropriate fixing part 500 according to the specifications of the elastic part 300 actually used, thereby improving the scope of application and interchangeability of the air-conditioning heat pump system pipeline vibration reduction device.

[0072] The installation steps of the pipeline vibration reduction device of the air conditioning heat pump system in this embodiment are as follows:

[0073] First, the elastic member 300 is installed by threading at both ends of the counterweight shuttle 200. The specific operation is to thread and tighten the straight section 320 of the elastic member 300 with the first internal threaded holes 220 at both ends of the counterweight shuttle 200 to ensure a firm and reliable connection.

[0074] Then, one end of the optional weight shuttle 200 equipped with the elastic member 300 is connected to the second internal threaded hole 430 of the limiting member 400. The specific operation is to tightly screw the straight section 320 of the elastic member 300 with the second internal threaded hole 430 of the limiting member 400 by the same threaded connection method. After the connection is completed, a tool is inserted into the tool hole 540 to open the groove 520 of the fixing member 500 to a certain angle so that the center hole 530 is inserted into the external thread 330 of the elastic member 300. At this time, the small diameter surface of the tapered limiting body 410 should face the elastic member 300. Such a design is helpful to effectively limit the elastic member 300 during vibration.

[0075] Afterwards, the vibration reduction assembly consisting of the connected counterweight shuttle 200, the elastic member 300, the stopper 400 and the fixing member 500 is placed into the tube body 100 from the flared portion 130 at one end of the tube body 100. The stopper 400 is also placed into the flared portion 130 at the other end of the tube body 100 and connected to the straight section 320 of the elastic member 300 through threads. Then, the slot 520 of the fixing member 500 is opened at an angle so that the center hole 530 thereof is inserted into the external thread 330 of the elastic member 300.

[0076] Finally, the entire air conditioning heat pump system pipeline vibration reduction device is connected to the air conditioning heat pump system pipeline 600 through the flared portion 130 of the pipe body 100. The design of the flared portion 130 facilitates docking with the system pipeline, ensuring the sealing and reliability of the connection, thereby ensuring that the refrigerant and other fluids flow normally in the pipeline, while the air conditioning heat pump system pipeline vibration reduction device can effectively play a vibration reduction role.

[0077] The working principle of the pipeline vibration reduction device of the air conditioning heat pump system in this embodiment is as follows:

[0078] When the pipeline 600 of the air-conditioning heat pump system vibrates, the kinetic energy of the vibration is transmitted to the counterweight shuttle 200 and the elastic member 300. The counterweight shuttle 200 together with the elastic member 300 will swing left and right or up and down. During this process, the counterweight shuttle 200 and the elastic member 300 generate reaction forces and interaction forces, thereby absorbing and dissipating the vibration energy, and transferring the external energy through inertial cancellation and dynamic tuning methods, so as to reduce the vibration. In this way, energy conversion and dynamic balance are achieved to achieve the purpose of vibration reduction. At the same time, the rugby shape design of the counterweight shuttle 200 can reduce the flow resistance inside the system pipeline during use. In addition, the internal fluid forms an air flow barrier on the surface of the counterweight shuttle 200, generating a reaction force to inhibit the counterweight shuttle 200 from over-swinging and hitting the pipe wall during the swinging process, so that it remains on the central axis of the pipe body 100, further enhancing the vibration reduction effect of the vibration reduction device.
