Micro Multiport Aluminum Tube For Air Conditioning Heat Exchangers 3102 / 3003 / 1100 / 1050
1. Product Description:
Micro-multiport aluminum 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.

4. Properties:
Multiport Extruded Aluminum Tube(MPE)- which is used for automobile air conditioner condenser has larger internal section area, better effectiveness for heat transfer. At the same time, has the following properties:
1). Lower energy costs
2). Higher performance
3). Less space and weight
4). High corrosion and pressure resistance
5). High recycling value
6). Pressure drop and silent solution
5.Applications:
Micro multi-port tube is applied not only in car air conditioner but also in the field of commercial, household air conditioner, condenser, evaporator, fridge, oil cooler and inter cooler.
Beside increased global performances, an all-aluminium brazed heat exchanger using Micro-multiport aluminum tube will also present better corrosion resistance.
6. Corrosion Resistance:Salt spray test: ≥ 750 hours
7. Multiport Extruded Aluminum Tube are available in various sizes and alloys, ensuring the best properties for the purpose required.
