Micro-channel tubes for heat exchanger
1.Introduction of Micro-channel tubes for heat exchanger
As the micro-channel aluminum flat tube has light weight, high thermal conductivity, good corrosion resistance, easy bending and deformation, and high recycling value, it is widely used in air-conditioning pipelines, power control pipelines, fuel pipelines, diesel oil return pipelines and heat exchange etc applications in the pipeline.
The Micro-channel tubes for heat exchanger produced by our company also have the characteristics of small size deviation range and high surface quality. In addition, our company has the leading domestic straightening and cutting technology to ensure the quality of the cut end face and the consistency of the products of the Micro-channel tubes for heat exchanger produced by our company.
