Abstract
A new cooling technology for a system of arrays of heated cylinders using winding cooling air is shown.The new cooling technology decreases the temperature differences among heated cylinders. The highest temperature exists in the midst of the cylinders, because the distance between them is very small and the cylinders generate heat uniformly. The winding cooling air runs to the right of the cylinders and then along their axis. The temperature differences among heated cylinders are decreased when the pitches between cylinders increase in flow direction.
