Abstract: PURPOSE:To enable execution of efficient cooling by setting the length of one side, the thickness, the interval and the height of fins at specified values and by providing minute indentations on the surface of each fin or by forming the fin in the shape of a letter S or a zigzag. CONSTITUTION:Dimensional limits on the maximum height, width, depth, etc., of cooling fins and an aimed resistance value thereof are set, and the number of the fins, the height of the fins, the width of the fins, the depth of the fins, the thickness of each fin, etc., are determined. The air velocity at a board entrance satisfying an aimed thermal resistance value is assumed and a thermal resistance value and a pressure loss are determined. Then, it is judged whether the determined thermal resistance value satisfies the aimed value or not and whether the shape of the fin is to be altered or not, the relations of the shape of the fin with the air velocity at the board entrance and the pressure loss are plotted, and thereby the shape of the fin making them extremely small is found out. The cooling fins 1 are fitted on a semiconductor package 5 having a large number of pins 6. Since the cooling fins 1 are so optimized as to have the least pressure loss and the thermal resistance value of 1.5 deg.C/W or below, effective cooling of the semiconductor package 5 is enabled.
