Aluminum Micro-Channel Tube
Group is a leading manufacturer for micro channel porous Aluminium Flat tubes with more than 9 years.
After years of accumulation, the group have formed a complete Aluminium alloy reseash and developments,production system can meet different technical requirements.
Currently, we produce and offer a full range of Aluminium porous channel flat tubes which are widely used in condensors and evaprators of heating elements in the field of home appliance, constrction industry as well as automobiles.
The Aluminium micro channel tubes PME tubes( also called parallel flow aluminium flat tubes) is a kind of thin-walled porous flat tubes, which is made of refined aluminium rod, hot extrusion, zinc spraying and anti-corrosion treatment.current annual capacities is about 1200mts.
Description
Aluminum micro-channel tube is a kind of high-precision extruded aluminum tube, also called multi-port extrusion tube (MPE tube) and an aluminum micro-channel tube. This flat, rectangular extruded tube is made of several channels that increase heat transfer through a higher surface-per-volume ratio.
Aluminum micro-channel tubes are available in various sizes and aluminum alloys, ensuring the best performance for the purpose required, and can be delivered with zinc or flux coating, ready for assembly and oven brazing.
