Abstract
The utility model relates to a double metal column airfoil profile radiator, which is composed of an upper header tube and a lower header tube, screw interfaces of the upper header tube and the lower header tube, an alloy metal column wing and a corrosion resistant metal core tube of the alloy metal column wing, wherein the cross section shape of a column wing central tube is elliptical, the corrosion resistant metal core tube has the same elliptical cross section shape and is fixed on the inner surface of the central tube in an expansion mode, and two ends are respectively communicated with the upper header tube and the lower header tube with the same materials. The surface area of the central tube whose cross section shape is elliptical and a core tube which has the same cross section shape is bigger than the surface area of the cylindrical central tube with the same cross section area and the core tube, and thereby the heat dissipation effect of the former is stronger that that of the latter under the condition that the column wing volume is not increased. An elliptical core tube enables hot water in the tube to be in turbulent flow condition, which can effectively avoid forming scale deposit and is beneficial for the radiator to operate stably, and thereby the service life of the radiator can be prolonged. The radiator has the prominent advantages of novel structure, simple manufacture, good heat dissipation effect and long service life.
