Product Description

1.Product Introduction

Micro channel aluminum flat tube (also called "parallel flow aluminum flat tube") is a thin-walled porous flat tubular material that uses refined aluminum rods, through hot extrusion, and surface-sprayed with zinc for corrosion protection. It is mainly used in various refrigerants. In the air-conditioning system, as the piping parts that carry the new environmentally friendly refrigerant, the new environmentally friendly system is the key material for the new generation of parallel flow micro channel air conditioning heat exchanger.

3.Product Feature And Application
Due to the high technical content of the micro channel aluminum flat tube, the production is extremely difficult. The minimum variety is 12mm in width and 1mm in thickness, but it has 12-16 holes. The difficulties are mainly reflected in the following 6 aspects:
1. Large extrusion ratio
The extrusion ratio refers to the ratio between the cross-sectional area of the material before hot extrusion and the cross-sectional area after extrusion. Generally, it is 8-50 times, while the cross-sectional area of the micro channel aluminum flat tube is only about 4px2. It reaches more than 400 times, which is more than 8 times that of the aluminum extrusion limit process.
2. Ultra-high dimensional accuracy
The dimensional accuracy of the micro channel aluminum flat tube is much higher than the national standard of "Hot Extrusion Tube for Research on Aluminum and Aluminum Alloy". According to national standards, the typical product has a width of 16mm and the size deviation is ±0.3mm, while the micro channel aluminum flat tube has a width of ±0.03mm, and the high requirements may even be increased to ±0.01~±0.02mm.
3. Air tightness
A set of micro-channel heat exchanger has about 50-150 micro channel aluminum flat tube. As long as one air-tightness defect (such as pores, inclusions, etc.) occurs, the entire air conditioner will be scrapped. Therefore, the quality standard is based on PPM (1 million Pieces), the measurement standard is less than 15PPM.
4. High quality bar
The minimum limit wall thickness of the micro channel aluminum flat tube is only 0.13mm. If the purity and hydrogen content of the cast rod material cannot meet the requirements, as long as there is a very small pore or inclusion, the thin wall of the micro channel aluminum flat tube will be produced. Leakage, so high-purity refining rods must be used, with a hydrogen content of ≤0.09%.
5. Surface zinc spraying technology
Because there is a refrigerant medium in the micro channel aluminum flat tube and atmospheric corrosion outside, it is easy to leak due to pitting corrosion. A thin layer of zinc must be sprayed on the outer surface of the microchannel aluminum tube to protect the tube wall from corrosion. There is no domestic manufacturer that can provide qualified zinc spraying equipment, and only a very small number of manufacturers in the world can provide it.
6. Online flaw detection and testing technology
Due to the difficulty and difficulty of micro channel aluminum flat tube technology, how to use scientific and effective online flaw detection and surface quality inspection methods in the production process to detect (mark) defective products in time and control the quality of microchannel aluminum tubes Extremely critical.
