Cooling copper finned tube is the finned copper pipe used for cooling. As a heat transfer core component, finned tube work under a harsh condition of high temperature, high pressure and corrosion, which require that finned tube should hold higher performance index: anti-corrosion, anti-wear, lower contact resistance, higher stability and dust proof.
