The friction stir welding radiator has the following advantages: 

(1)It realizes the fabrication of the structure of the super-wide and large size radiator with high power, and solves the technical bottleneck of the profile radiator; 

(2) Friction welding is a kind of non-medium heat fusion, which is equivalent to one-step extrusion molding of profile, and can achieve 100% thermal conductivity of the original profile

(3)Lower development cost, 

(4)Shorter development cycle

(5)High stability and easy maintenance of the friction stir welding radiator.
