Product Description

Copper tube:A type of nonferrous metal tube, it is a pressed and drawn seamless tube.

Copper tubes have good electrical and thermal conductivity properties, and are the main material for conductive and heat dissipation accessories of electronic products. They have become the first choice for modern contractors to install water pipes, heating and cooling pipes in all residential commercial houses. Copper tubes have strong corrosion resistance, are not easy to oxidize, and are not easy to react chemically with some liquid substances, and are easy to bend and shape.

Copper tubes have many uses, and the following are some common application areas:
1. Construction: In the construction field, copper tubes are widely used in water supply pipes, heating pipes, and air conditioning and refrigeration systems. The thermal conductivity and corrosion resistance of copper tubes make them an ideal material to ensure long-lasting water supply and heating effects.

2. Refrigeration and air conditioning: Copper tubes play an important role in refrigeration and air conditioning systems. It is used as a transmission pipeline for refrigerants, and its high thermal conductivity and corrosion resistance ensure efficient heat exchange.

3. HVAC: Copper tubes are also widely used in heating pipes and radiators in HVAC systems, and their high thermal conductivity helps to quickly transfer heat.

4. Petrochemical: Copper tube manufacturers say that because copper has good corrosion resistance to many chemicals, copper tubes are often used in pipelines for transporting and processing liquids or gases in the petrochemical field.

5. Electronic and electrical fields: The high conductivity of copper tubes makes it a common material in the electronic and electrical fields, and is widely used in wires, cables, circuit boards, etc.

6. Transportation: Copper tubes play an important role in the manufacture of vehicles such as cars, trains and airplanes, and are used to transmit liquids and gases, such as brake systems, fuel systems, etc. In addition, copper tubes can also be used in art decoration, furniture making, water heaters, daily necessities and other fields. In general, the wide application of copper tubes is attributed to their good thermal conductivity, electrical conductivity, corrosion resistance and easy processing and installation.

  Why do we choose copper tubes for air conditioning and refrigerator refrigeration?

1. Thermal conductivity: Copper tubes have excellent thermal conductivity and can quickly conduct heat and cold, allowing air conditioners and refrigerators to quickly reach the required temperature and improve the cooling effect. In contrast, aluminum tubes have relatively poor thermal conductivity and slow heat transfer, so they may be slightly inferior to copper tube freezers in terms of cooling speed and effect.

2. Corrosion resistance and high temperature resistance: Copper tubes have good corrosion resistance and high temperature resistance, and can maintain good performance during long-term use. This is especially important for air conditioners and refrigerators that require long-term stable operation. Aluminum tubes are relatively fragile and easily affected by the external environment, and are prone to problems such as air leakage.

3. Mechanical strength: Copper tubes have good stability, long service life, and are not prone to corrosion. At the same time, the thermal conductivity of refrigeration copper tubes is much better than that of aluminum tubes, and its welding performance and mechanical strength are also much better than aluminum.

4. Safety: Copper is a natural antibacterial material that does not release harmful substances, which can ensure the safety and health of the ingredients in the refrigerator.

 

Although the price of copper tube freezers is relatively high, its excellent performance and durability make copper tubes the preferred material in air conditioner and refrigerator manufacturing. Whether from the perspective of refrigeration effect, durability, safety or economy, copper tubes are a more ideal choice.
