3003 / 3102 Micro-Multiport Aluminum Tube For Radiator Welding
Product Introduction:
Micro Multiport Extruded Aluminium Tube,is a kind of thin porous
flat tubular material,which is treated by surface spraying
zinc,using refining aluminum bar by hot extrusion.
Aluminum extruded tube for air Condition tube is the main component part of air-conditioning and the parallel Flow evaporators and condensers of other refrigeration equipments.
It is mainly used in all kinds of air conditioning refrigerants
system.As a bearer of new environment-friendly refrigerant piping
components,it is a key material applied in the new generation of
parallel flow microchannel air conditioning heat exchanger and the
heat exchange system.

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 characteristics:
1. Excellent conduction of heat
2. Excellent corrosion resistance
3. High cycle reuse value
4. High surface quality
5. Low weight
6. High compressive reinforcement
Beside increased global performances, an all-aluminium brazed heat
exchanger using MPE will also present better corrosion resistance.
MPEs are primarily used for the following applications:
Condensers
Evaporators
Oil coolers
Radiators
Heater cores
Other sizes not mentioned above can also be according to the
technical requirements of user drawing.
Features of our aluminum flat tube:
Presently the aluminum Micro-multiport tube parallel flow heat exchanger is the unique
approach to Substantially save energy and cut the cost in air
conditioning equipments for Private and commercial use and can make
your products environment-friendly.
Package: In coil or Straight with fixed length.
Surface Treatment : With Zinc spraying or without Zinc spraying.
