Why are copper tubes used in household air conditioners and aluminium tubes for automotive air conditioners?
The difference between the copper tube and the aluminum tube is mainly the price difference, and this difference is also very big.The use of aluminum tubes in air conditioning may result in the quality of aluminium and copper welds.
The quality of the copper tube and the quality of welding are not suitable for long time moving and bumping
The difference between air conditioning copper tube and aluminum tube:1 、 the material of copper tube and aluminum pipe is different.2, the copper pipe and aluminum pipe flow is different.3, copper and aluminum prices are different: Copper costs high.4, the application of copper and aluminum, brass, good ductility, resistance to oxidation, bellbottom do good pressure resistance, not easy leakage of refrigerant, are often used in air conditioning; aluminum can do bell, pressure difference of oxidation resistance, it is prone to leak, if not good insulation cotton, it is a hidden danger.5, copper and aluminum bending: aluminum tube bending, better than copper bending resistance.
The air conditioning copper tube is a kind of pressed and drawn seamless pipe. The air conditioner copper tube has the advantages of light weight, good heat conductivity and low temperature intensity. Copper tubes are often used as connecting pipes for air conditioners. Air conditioning aluminum tube is also a kind of non-ferrous metal pipe. The air conditioning aluminum tube is made of pure aluminium or aluminum alloy and is extruded into a hollow metal tube with longitudinal length. Air conditioning aluminum tube has "annealing, quenching and hot state, medium plasticity, good weldability, weldability" and so on. Aluminium tubes are also used for air conditioning. But for the moment, copper tubes are more suitable for air conditioning than aluminum tubes.
