The heat exchanger of wind turbines is the fact that in power production plants are not specific details, so the same position and the same task, it can also have different manufacturing solutions. Fan of heat exchanger tower in the power production line Ba Ria - Vung Tau Thermal Power Plant, which was provided by foreign countries before, is made from deformed aluminum alloy material with tendons. stiffening and inner support bars. With such a structure for the wing system worked very well, it was verified through its operating time.
