Abstract
PURPOSE: To prevent generation of fatigue damage by installing spiral fins each having different sectional form onto the edge area of the fin attaching part of the rotary shaft equipped with spiral fins, thereby reducing temperature variation.
CONSTITUTION: The spiral-shaped fins 6 each of which is divided into one or more parts in the direction of a rotary shaft are installed, and a fin 7 having the heat transfer coefficient less than the fin 6 described before is installed at the terminal edge on the fluid B side. Then, the rotary shaft 1 heated by the fluid B is cooled through the spiral fins 6 by the fluid A, and the temperature gradient in the rotary shaft 1 can be made smooth because of the existence of the fin 7. Thus, the width in the temperature variation on the rotary shaft 1 and fins 6 and 7 is reduced, and the variation stress generated is reduced, and fatigue damage can be prevented beforehand.
