Description

Technical Field

[0001] This utility model relates to the technical field of air conditioner connecting pipes, and more specifically to an air conditioner connecting pipe with good noise reduction effect. Background Technology

[0002] As a key component of the refrigeration system, the technology development of air conditioning connecting pipes has gone through three stages: Early indoor and outdoor units were connected using ordinary copper pipes, which suffered from easy oxidation and poor flexibility. After 2000, the industry gradually promoted internally threaded copper pipes, which improved thermal conductivity by more than 20% by increasing the heat exchange area. However, wrinkles easily appeared when bending, affecting refrigerant flow. Since 2015, with the popularization of environmentally friendly refrigerants such as R32, connecting pipe technology has undergone innovation: on the one hand, double-layer anti-oxidation copper pipes (such as TP2M copper) are used, with phosphorus deoxidation treatment on the inner wall, increasing the pressure resistance to over 5MPa; on the other hand, composite insulation structures have been developed, upgrading the traditional PE insulation layer to EPDM rubber + aluminum foil reflective layer, improving insulation performance by 30%.

[0003] In recent years, the widespread adoption of inverter air conditioners has placed higher demands on connecting pipes, leading some manufacturers to apply shape memory alloy anti-fracture joints and nano-coating anti-corrosion technology. The latest industry standards (such as GB / T17791-2017) have made stricter provisions for pipe wall thickness and welding processes, driving the development of connecting pipes towards higher efficiency, weather resistance, and lightweight designs.

[0004] During use, existing air conditioning connecting pipes generate a lot of noise due to the high internal fluid flow rate, making it difficult to control the noise generated by the equipment. Utility Model Content

When noise is generated by liquid flowing through 101, the sound enters the inner side of the main reflective cone 501, and then part of it is reflected by the inner side of the main reflective cone 501. The sound wave is reflected to the outside of the adjacent main reflector cone 501, and then reflected by 503, the reflective arc plate 504 and the outer wall of the pipe body 1. This will consume the energy of the sound wave that enters the inner wall of the main reflector cone 501. The sound wave passes through the second reflective cone plate 404, the first reflective cone plate 403, the outside of the main reflector cone 501 and the third reflective cone plate 505, which can effectively reduce the noise generated when the water source passes through the inside of 101 and effectively reduce the noise generated by the operation of the equipment.

[0021] In a preferred embodiment, the cross-sections of the first reflective cone plate 403 and the second reflective cone plate 404 are perpendicular to the outer side of the main reflective cone 501, the outer diameter of the third reflective cone plate 505 is five millimeters smaller than the inner diameter of the noise reduction sleeve 401, and the distance between the edge of one side of the first reflective cone plate 403 and the second reflective cone plate 404 and the main reflective cone 501 is five millimeters.

[0022] The working principle of this utility model is as follows: When liquid flows through the interior of 101 and generates noise, the sound enters the inner side of the main reflector cone 501. Then, through reflection on the inner side of the main reflector cone 501, some of the sound waves are reflected to the outer side of the adjacent main reflector cone 501. Then, the sound waves are reflected by 503, the reflective arc plate 504, and the outer wall of the pipe body 1, which consumes the energy of the sound waves that entered the inner wall of the main reflector cone 501. The sound waves pass through the second reflective cone plate 404, the first reflective cone plate 403, the outer side of the main reflector cone 501, and the third reflective cone plate 505, which can effectively reduce the noise generated when the water source passes through the interior of 101, and effectively reduce the noise generated by the operation of the equipment.
