Hello Guest,

Copper has a high heat conductance, and is also resistant to corrosion by thte cooling liquids and gases which are used.

At one point, Aluminium was extensively used in coolers, but after some 20 years (5 years in some cases) the corrosion ate through, the refrigerant and lubricating oil escaped, resulting in seizure of the sealed unit compressor.

So...That's why Copper is extensively used.

Kind Regards....

Copper tube is used on refrigerating systems for the vapour and liquid circulation lines because of its chemical compatibility with refrigerants (but not ammonia), its total impermeability and ease of jointing, bending and installation.

Also, it has a very high thermal conductivity to transfer heat in condensers and evaporators.
