THERMAL RADIATION FINS AND METHOD FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide thermal radiation fins capable of improving a cooling efficiency by a simple configuration and further capable of attaining a high performance. SOLUTION: Each of a plurality of flat plate-like fins 6 extending along a flowing direction of cooling fluid is arranged in rows in a direction crossing at a right angle with a flowing direction. With such an arrangement as above, each of the fins 6 is integrally formed with a plurality of first fin sections 6a arranged in spaced-apart relation along a flowing direction with a clearance P being left so as to be positioned in the same plane and also with a plurality of second fin sections 6b positioned at locations where each of the first fin sections 6a is not present and spaced apart in a direction crossing at a right angle with the flowing direction in respect to each of the first fin sections 6a in the same plane so as to be off-set from each other.
