Description

Technical Field

[0001] This utility model relates to the field of air conditioning copper pipes, and more particularly to a corrosion-resistant copper pipe for air conditioning refrigeration. Background Technology

[0002] An air conditioner is a device used to regulate indoor air temperature, humidity, and air quality, creating a comfortable environment by cooling or heating the air. It is widely used in homes, offices, shops, and other places. Copper pipes play a crucial role in the air conditioning refrigeration cycle because copper has excellent thermal conductivity, enabling it to quickly conduct heat and effectively transfer heat from the refrigerant, thus improving cooling efficiency. Furthermore, copper pipes are easy to bend and shape, giving them high flexibility during installation and allowing them to adapt to different installation environments and spatial layouts. Copper pipes can also withstand high pressure, maintaining structural stability during high-pressure refrigerant circulation and ensuring the safe operation of the system.

[0003] In the process of developing this application, the inventors discovered the following problems with the existing technology: When fluid flows inside copper pipes, the chemical composition of the fluid may cause localized corrosion, such as crevice corrosion. After a period of time, this localized corrosion may lead to pipe rupture or leakage. Furthermore, copper pipe corrosion problems may lead to frequent maintenance and replacement, thereby increasing long-term operating costs. Simultaneously, pipe corrosion can cause metal ions to enter the fluid, potentially affecting fluid quality and reducing the overall performance of the equipment.

[0004] Therefore, those skilled in the art have provided a corrosion-resistant copper pipe for air conditioning refrigeration to solve the problems mentioned in the background art. Utility Model Content

Both the input and output ends of the copper pipe body 1 are rotatably equipped with externally threaded connecting rings 2. The copper pipe body 1 includes a wear-resistant layer 101, a connecting layer 102 at the inner end of the wear-resistant layer 101, a base layer 103 at the inner end of the connecting layer 102, and an anti-corrosion coating 104 at the inner end of the base layer 103. The wear-resistant layer 101 is made of austenitic stainless steel with a thickness of 80-150 μm. The connecting layer 102 is made of copper-based brazing alloy with a thickness of 30-50 μm.

The base layer 103 is made of oxygen-free copper. Oxygen-free copper not only has good electrical conductivity but also strong corrosion resistance, helping to avoid metal corrosion caused by environmental factors, thereby improving the pipeline's service life. For longevity and safety, the anti-corrosion coating 104 is made of polytetrafluoroethylene, providing a low coefficient of friction, reducing fluid flow resistance, thereby improving energy efficiency and reducing energy consumption, which helps reduce operating costs. In addition, the use of anti-corrosion materials can effectively resist corrosive substances such as condensate and chemical gases, improving the durability of the pipeline and ensuring safe operation in various environments.

Austenitic stainless steel significantly improves the wear resistance of the outer surface of the copper pipe, which means less wear in high flow or high pressure environments, thus extending service life. The connecting layer 102 is made of copper-based brazing alloy, ensuring a firm connection between the wear-resistant layer 101 and the base layer 103, enhancing the overall strength and durability of the structure, and improving the reliability of the system. The base layer 103 is made of oxygen-free copper. Oxygen-free copper not only has good electrical conductivity but also strong corrosion resistance, helping to avoid metal corrosion caused by environmental factors, thereby improving the service life and safety of the pipeline.
