Save cost and reduce weight
Weight reduction will be 15 per cent when heatexchangers adopt two-piece folded tube. Total costsaving will be 5–20 per cent for a two-piece folded tube heat exchanger.
Excellent thermal performance
The tube wall thickness can be reduced up to 20 per cent when compared to that of a traditional extruded tube, providing a larger free flow area for the refrigerant, thus reducing refrigerant side pressure drop. Small hydraulic diameter, along with the micro-channel flow characteristics, provide for excellent heat transfer on the refrigerant side.
