Description

Technical Field

[0001] This utility model belongs to the field of refrigeration equipment technology, and in particular relates to a steel pipe silencer for refrigeration equipment. Background Technology

[0002] Refrigeration equipment is used to lower or control temperature and is widely used in home appliances, industrial production, food storage, air conditioning, cold chain logistics, and other fields. Common refrigeration equipment includes refrigerators, freezers, air conditioners, chillers, freezers, cooling towers, and compressors.

[0003] Copper pipes are one of the most commonly used piping materials in refrigeration equipment. They possess excellent thermal conductivity, corrosion resistance, and machinability, and are frequently used to connect evaporators, condensers, and compressors in refrigeration systems. Steel pipes used in refrigeration equipment are primarily for piping connections and transmission within the refrigeration system, ensuring refrigerant flow and maintaining normal system operation.

[0004] When refrigerant flows in pipes in a refrigeration system, noise is generated due to factors such as fluid velocity, pressure, and the roughness of the pipe's inner surface. This noise is usually called "fluid noise," and it is typically caused by the flow or turbulence of liquids or gases.

[0005] Silencing the steel pipes in refrigeration equipment can greatly reduce the noise impact of the equipment. However, most steel pipes in existing refrigeration equipment do not have silencing function. Therefore, this application proposes a steel pipe silencer for refrigeration equipment.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0022] Example

[0023] Please see Figure 1 , Figure 2 and Figure 3The present invention provides a technical solution: a steel pipe silencer for refrigeration equipment, comprising a first steel pipe 1 and a second steel pipe 2, wherein a silencer assembly is provided between the first steel pipe 1 and the second steel pipe 2;

[0024] The noise reduction assembly includes a first sleeve 3 and a second sleeve 5. The first sleeve 3 is sleeved on the end of the first steel pipe 1. Specifically, the first sleeve 3 is tightly welded to the first steel pipe 1. The second sleeve 5 is sleeved on the end of the second steel pipe 2. Specifically, the second sleeve 5 is tightly welded to the second steel pipe 2. The first sleeve 3 and the second sleeve 5 are connected.

[0025] The first sleeve 3 has a corrugated pipe 10 inside. Specifically, the side wall of the corrugated pipe 10 is fixedly connected to the inner wall of the first sleeve 3. The corrugated pipe 10 is connected to the first steel pipe 1. The second sleeve 5 has several arc-shaped pipes 11 inside. Specifically, the two ends of the arc-shaped pipes 11 are fixedly connected to the inner wall of the second sleeve 5. The arc-shaped pipes 11 are open on one side pointing to the central axis of the second sleeve 5.

[0026] In this embodiment, both the corrugated pipe 10 and the arc-shaped pipe 11 are made of sound-absorbing material. The noise generated when the fluid flows in the first steel pipe 1 is buffered, slowed down and absorbed by the corrugated pipe 10 in the first sleeve 3 for the first round of noise reduction. Then, it is guided, dispersed and absorbed by the arc-shaped pipe 11 in the second sleeve 5 for the second round of noise reduction, thus achieving effective reduction of the noise of the fluid in the steel pipe in the refrigeration equipment.

[0027] Furthermore, the free end of the first sleeve 3 is provided with a first annular connecting block 4. Specifically, the first annular connecting block 4 is tightly welded to the first sleeve 3. The free end of the second sleeve 5 is provided with a second annular connecting block 6. Specifically, the second annular connecting block 6 is tightly welded to the second sleeve 5. The first annular connecting block 4 and the second annular connecting block 6 are adapted to each other.

[0028] In this embodiment, the first annular connecting block 4 and the second annular connecting block 6 cooperate with each other to facilitate the connection of the first sleeve 3 and the second sleeve 5.

[0029] Furthermore, threaded holes 7 are symmetrically provided between the first annular connecting block 4 and the second annular connecting block 6.

[0030] In this embodiment, bolts are passed through threaded holes 7 to fix the first annular connecting block 4 and the second annular connecting block 6, which facilitates installation and disassembly.

[0031] Furthermore, the inner diameter of the first annular connecting block 4 is adapted to the inner diameter of the first sleeve 3. The first annular connecting block 4 and the first sleeve 3 are provided with an assembly block 8. Specifically, the assembly block 8 is welded to the interior of the first annular connecting block 4 and the first sleeve 3. The assembly block 8 is provided with a through pipe 9. Specifically, the through pipe 9 is welded to the assembly block 8 and is connected to the first sleeve 3. The through pipe 9 extends into the interior of the second sleeve 5.

[0032] In this embodiment, fluid leakage can be reduced by guiding the fluid through the through pipe 9.

[0033] Furthermore, a sponge rod 12 is embedded inside the arc-shaped tube 11.

[0034] In this embodiment, noise is further reduced by embedding sponge rods 12 and utilizing the porous adsorption effect of the sponge rods 12.

[0035] Furthermore, the back sides of several arc-shaped tubes 11 are tightly fitted to the inner wall of the second sleeve 5.

[0036] In this embodiment, the arc-shaped tube 11 fits against the inner wall of the second sleeve 5 to prevent fluid from entering between the arc-shaped tube 11 and the second sleeve 5.

[0037] The working principle and usage process of this utility model: After the utility model is installed, work according to the above implementation method until all working steps are completed.
