Description

Technical Field

[0001] This application pertains to pipe fittings in air conditioning systems, and more specifically, relates to a pipe assembly adjacent to or connected to a compressor. Background Technology

[0002] The compressor is the core component of modern air conditioning products. It can heat and pressurize the refrigerant through reciprocating compression motion. However, it is inevitable that the compressor will vibrate when it runs at high speed. This vibration can be transmitted to the pipes adjacent to or connected to the compressor, causing the pipes to vibrate and generate resonance noise. Therefore, in order to reduce this resonance phenomenon, the common technology for air conditioning products is to add putty or blocks to the pipes that are prone to vibration. However, this vibration reduction method has poor vibration reduction effect in actual application and is difficult to meet the vibration reduction requirements of existing air conditioning pipes. Utility Model Content

[0003] Therefore, it is necessary to provide a pipe assembly to address the above problems. The specific technical solution is as follows:

[0004] A pipe assembly for an air conditioning system, characterized in that the pipe assembly includes a pipe fitting and a counterweight, the counterweight being made of stainless steel and welded to the pipe fitting.

[0005] The pipe assembly provided in this application includes, firstly, a counterweight made of stainless steel, which has a high relative density and requires less space than putty or blocks; secondly, stainless steel has excellent aging resistance and a long service life; and thirdly, the counterweight is welded and fixed to the pipe assembly, making the connection more secure, effectively controlling the center of gravity of the counterweight and the air conditioning pipe assembly, effectively avoiding the compressor's natural frequency, reducing the vibration of the pipe assembly, and extending its service life.

[0014] To make this application clearer, specific embodiments are described below with reference to the accompanying drawings:

[0015] The compressor is the core component of modern air conditioning products. It can heat and pressurize the refrigerant through reciprocating compression motion. However, it is inevitable that the high-speed operation of the compressor will generate significant vibration. This vibration can be transmitted to the pipes adjacent to or connected to the compressor, easily causing the pipes to vibrate and generate resonance noise. Therefore, in order to reduce this resonance phenomenon, the common technology for air conditioning products is to add putty or blocks to the pipes that are prone to vibration. However, this vibration reduction method has poor vibration reduction effect in actual application and is difficult to meet the vibration reduction requirements of existing air conditioning pipes.

[0016] To solve the above problems, see Figures 1-7 This application provides a pipe assembly for an air conditioning system. The pipe assembly 100 includes a pipe fitting 1 and a counterweight 2. The counterweight 2 is made of stainless steel and is welded to the pipe fitting 1. Providing such a pipe assembly 100 has several advantages: First, the stainless steel counterweight 2 has a high relative density, requiring less space compared to putty or adhesive blocks. Second, stainless steel has excellent aging resistance and a long service life. Furthermore, the welding and fixing of the counterweight 2 to the pipe fitting 1 ensures that the position and orientation of the counterweight 2 are completely determined and firmly connected, effectively controlling the center of gravity of the counterweight 2 and the air conditioning system's pipe assembly 100, effectively avoiding the compressor's natural frequency, reducing vibration of the pipe assembly 100, and extending its service life.

[0017] To facilitate the connection between the counterweight 2 and the pipe fitting 1, the counterweight 2 includes a connecting hole 20. The connecting hole 20 extends through the counterweight 2 along its centerline. The inner wall of the connecting hole 20 is welded to a portion of the outer wall of the pipe fitting 1. The welding method can be furnace welding, flame brazing, etc. Before welding the counterweight 2 and the pipe fitting 1, the counterweight 2 is fitted onto the outside of the pipe fitting 1, meaning the pipe fitting 1 is inserted into the connecting hole 20. Furthermore, the connecting hole 20 is pre-fixed to the outer wall of the pipe fitting 1 with an interference fit, facilitating subsequent welding. Several embodiments of the counterweight 2 are described below:

[0018] See Figure 2-3 This application provides an embodiment of the counterweight 2, which is a split type. The counterweight 2 includes a first counterweight sub-block 211 and a second counterweight sub-block 212. The first counterweight sub-block 211 includes a first connecting surface 2111 and a first inner arc surface 2112. The second counterweight sub-block 212 includes a second connecting surface 2121 and a second inner arc surface 2122. The first inner arc surface 2112 and the second inner arc surface 2122 form the inner wall surface of the connecting hole portion 20, which is welded and fixed to the pipe fitting 1. The first connecting surface 2111 and the second connecting surface 2121 are arranged opposite to each other, and they can be pressed together or welded together.

[0019] The first inner arc surface 2112 and the second inner arc surface 2122 constitute the inner wall surface of the connecting hole portion 20. That is, when the first connecting surface 2111 and the second connecting surface 2121 are pressed together or welded together, the first inner arc surface 2112 and the second inner arc surface 2122 are arranged opposite each other and enclose the connecting hole portion 20. Specifically, the first inner arc surface 2112 and the second inner arc surface 2122 have the same diameter. Preferably, for ease of processing, both the first inner arc surface 2112 and the second inner arc surface 2122 are semi-circular arc surfaces. Furthermore, the first counterweight block 211 and the second counterweight block 212 have the same structural dimensions. Preferably, both the first counterweight block 211 and the second counterweight block 212 are semi-cylindrical. This arrangement facilitates processing and assembly.

[0020] The first connecting surface 2111 and the second connecting surface 2121 are arranged opposite each other, and can be pressed together or welded together. Specifically, when the first connecting surface 2111 and the second connecting surface 2121 are arranged opposite each other and pressed together, the first inner arc surface 2112 and the second inner arc surface 2122 are arranged opposite each other and enclose to form a connecting hole 20. The connecting hole 20 is sleeved on the outside of the pipe fitting 1. In order to fix the counterweight 2, the inner wall of the connecting hole 20 can be welded to the outer wall of the pipe fitting. Before welding, solder can be applied to the inner wall of the connecting hole 20, or a welding ring can be placed at or near the mating part of the pipe fitting 1 and the connecting hole. Then welding is performed. In this way, the solder melts under the action of high temperature and penetrates into the mating gap between the pipe fitting 1 and the connecting hole 20. After the solder cools and solidifies, the two are fixedly connected. Furthermore, solder can be applied to the mating parts of the first connecting surface 2111 and the second connecting surface 2121, or a solder ring can be placed there, which helps to improve the connection strength of the first counterweight sub-block 211 and the second counterweight sub-block 212.

[0021] See appendix Figure 4-7 This application also provides another embodiment of the counterweight 2, which is an integral structure. The counterweight 2 includes a connecting hole 20 and an opening 22. The opening 22 includes an opening 220. Along the axial direction of the counterweight 2, the opening 220 penetrates the thickness direction of the counterweight 2. Along the radial direction of the connecting hole 20, the opening 220 penetrates the inner peripheral wall of the connecting hole 20 and the outer peripheral wall of the counterweight 2.

[0022] Specifically, the opening 22 is provided to facilitate fitting the pipe fitting into the connecting hole 20 of the pipe fitting 1. The minimum width of the opening 22 must not be less than the outer diameter of the pipe fitting 1, so that the pipe fitting 1 can enter the connecting hole 20 through the opening 22. Further, the opening 22 includes a first inner sidewall 221 and a second inner sidewall 222. Preferably, the first inner sidewall 221 and the second inner sidewall 222 are arranged opposite to each other and parallel to each other. The distance W between the first inner sidewall 221 and the second inner sidewall 222 is equal to the diameter D of the connecting hole 20. The distance W between the first inner sidewall 221 and the second inner sidewall 222 can also be understood as the width of the opening. For ease of assembly and welding, the pipe fitting 1 and the connecting hole 20 are interference-fitted, with the outer diameter d of the pipe fitting equal to the diameter D of the connecting hole 20, and the error equal to the interference amount between them.

[0023] In this embodiment, the counterweight 2 can be eccentric or non-eccentric. For ease of processing, it is preferable that the cross-section of the counterweight 2 is circular, meaning the counterweight 2 is cylindrical. The pipe section where the pipe fitting 1 and the counterweight 2 mate is defined as the mating section. When the counterweight 2 is non-eccentric, the center of the mating section's cross-section coincides with the center O of the counterweight 2's cross-section. When the counterweight 2 is eccentric, the center of the mating section's cross-section deviates from the center O of the counterweight 2's cross-section. In other words, there is a radial distance between the center of the mating section's cross-section and the center O of the counterweight 2's cross-section. The specific distance needs to be determined based on the system's performance. It should be noted that the axis of the connecting hole 20 is aligned with the axis of the mating section. The mating section can be a straight pipe or a bent pipe, preferably a straight pipe, to facilitate the processing of the counterweight.

[0024] Furthermore, fitting 1 can be made of stainless steel or copper. That is, fitting 1 can be made of the same material as counterweight 2, both being stainless steel; alternatively, fitting 1 and counterweight 2 can be made of different materials, with fitting 1 made of copper and counterweight 2 made of stainless steel. Preferably, fitting 1 and counterweight 2 are made of the same stainless steel, which can relatively reduce system costs, and connecting components made of the same material is relatively easier.

[0025] See Figure 1 The pipe fitting 1 includes a bend section 10 and a straight section 11. The counterweight 2 is preferably fixedly installed at one end of the straight section 11 near the bend section 10. This pipe assembly 100 is installed in the air conditioning system and is basically static. Therefore, the counterweight 2 is installed in the straight section 11, which has the following advantages: First, the structure of the connecting hole 20 is easy to process and does not need to be set to match the shape of the bend section 10; second, the straight section 11 is more suitable for scenarios that require multiple counterweights to be evenly distributed (such as anti-sagging counterweights for long-span pipes); third, the counterweight 2 is easier to disassemble and adjust in position by being installed in the straight section 11; in addition, the straight section 11 is subjected to uniform force, and the installation of the counterweight 2 has little impact on the stress of the pipe fitting 1.

[0026] The above examples illustrate the principles and implementation methods of the present invention. These embodiments are merely illustrative and intended to aid in understanding the method and core concepts of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the scope of protection of the present invention.
