摘要：
A heat-exchanging pipe having an inside surface formed with a plurality of ribs for enhancing turbulence of fluid flowing through the pipe. Each rib has an upstanding face portion formed on an upstream side of the rib and an inclined face portion descending from an upper end of the up-standing face portion in a downstream direction. The pipe is manufactured by roll forming a substantially flat piece of sheet metal material to form the ribs and then curling and joining ends of the sheet metal to form a substantially cylindrical pipe with the ribs on the inside surface thereof.
