Automobile Aluminum Radiator Flat Tube
1.The Introduction of Automobile Aluminum Radiator Flat Tube
Micro-channel aluminum flat tube is a thin-walled porous flat tube material using refined aluminum rods, hot extrusion, and zinc spray-proof treatment on the surface.
As a pipeline component carrying new environmentally friendly refrigerants, using of a new environmentally friendly system is the key material for a new generation of parallel flow microchannel air-conditioning heat exchangers. As a new type of environmentally-friendly refrigerant-carrying pipeline component, the micro-channel aluminum flat tube was first used in the automotive air-conditioning system. Mainly used in condensers, evaporators, air coolers etc parts of automotive air conditioning systems.
