Galvanized aluminum parallel flow pipe

The Galvanized aluminum parallel flow pipe (also known as parallel flow aluminum flat tube ) is a kind of thin-walled porous flat tube material, which is made of refined aluminum rod, hot extrusion, zinc spraying and anti-corrosion treatment. The Galvanized aluminum parallel flow pipe has refrigerant medium inside and atmospheric corrosion outside, which is easy to leak due to point corrosion. A thin layer of zinc must be sprayed on its outer surface to protect the tube wall from corrosion.
 
The specification of Galvanized aluminum parallel flow pipe:
 

Alloy	1100/3003/3102
Temper	O H112
Width	8-150mm
Zinc coating thickness	5g/mm2 -15g mm2

 

Galvanized aluminum parallel flow pipe has the following advantages:
 
1. the heat exchange efficiency between the refrigerant and the inner wall of the flat tube is increased by 40%, and the flow resistance of the refrigerant in the collector tube of the heat exchanger is reduced by 40%.
2. the fin heat exchange efficiency on the air side is increased by 40%, and the wind resistance of the air side heat exchanger is reduced by 40%.
3. the heat exchange performance of the whole heat exchanger is improved by 40%.
4. 40% less refrigerant than traditional technology.
5. comparison between all aluminum structure and copper aluminum structure: because there is no potential difference between copper and aluminum, the service life is longer.
6. the Galvanized aluminum parallel flow pipe can withstand the high pressure resistance limit of the existing refrigerant, with compact product structure, light unit weight, short process flow, high manufacturing reliability and relatively low cost.
 
 
Galvanized aluminum parallel flow pipe are widely used as heat exchangers for condensers, evaporators for automotive air conditioning systems, and radiators for engine cooling systems.
