Aluminium Micro-channel Tube

  1. Aluminium Micro-channel Tube is a kind of high precision extruded aluminium tube, also called multi-port extrusion tube (MPE tube) and aluminium micro multi-channel tube. This flat and rectangular extruded tube is made of several channels that increase the heat transfer through a higher surface per volume ratio.
  2. Aluminium Micro-channel Tubes are available in various sizes and aluminium alloys, ensuring the best performance for the purpose required and can be delivered with zinc or flux coating, ready for assembly and oven brazing.

Features

No need for extra brazing in brazing line but use aluminium fin material with a layer

The Si-flux to spray solder flux when brazing and the fin material can be bare foil

 

The tube with zinc-coated will highly enhance  corrosion resistance performance

Advantages of Silicon Flux Coated Aluminium Micro-channel Tube

Comparing with traditional aluminium tube, aluminium micro-channel tube with solder layer on the surface has a greater advantage:

1. Improve quality, enhance brazing, guarantee 100% brazing quality anti-corrosion, and environment-friendly.

2. Reduce cost: cheaper fin material replaces composite clad fin material, the thickness can be reduced up to 30%, reduce cost greatly, lower consumption of solder, fewer defects.

3. Working condition improvement: no flux particles in the air, reduction of effluent, and harmful gas sent out.

 

working principle of Aluminium Micro-channel Tube

 


Micro-channel Technology in Heat Exchanger

Aluminium micro channel tube is the alternative solution to cooper tube and welded aluminium manifolds for increasing efficiency and reducing the overall cost.

● Reduce your system refrigerant charge by as much as 35 %.

● Improve your energy efficiency/coefficient of performance by up to 10 %.

● Reduce your raw material consumption by more than 40 %.

● Reduce your manufacturing cost compared to aluminium and copper heat exchangers.

● Easily recycle.
