Micro-multiport tube is the high-tech aluminum products under the process of hot extrusion from refined aluminum ingot and then zinc spraying for anti-corrosion.
Micro-multiport tube is the core materials of new generation parallel flow air conditioning heat exchangers. It is outstanding in enviromental-friendly, efficient, energy-saving and cost reduction and was approved vividly in automobile air conditioning system. With restriction and prohibition of the application of the traditional refrigerant, it is a trend that household and commerical air conditioning heat exchanger needs revolution.
