SunPower - Various Special Shaped Tubes for Effective Heat Transfer

Corrugated low finned tubes are special shaped tube with ripples on inner pipe wall and thread arc fillisters on outer pipe wall, which can enhance the impulsive motion of turbulent current of the fluid in and out of the pipe, change the flow state between fluid layer and pipe wall, break the boundary layer, intensify heat transfer and clean up the dirt while the fluid flushes the pipe wall, The heat transfer coefficient of corrugated low finned pipe is 1.3 to 2.2 times of that of normal pipe.
