Title: Semiconductor package provided with heat sink
Inventor: HOJO SAKAE
IPC: H01L23/36
Filed: 1993-12-24
Abstract: PURPOSE:To improve the cooling efficiency of a package at the time of air- cooling, by making the sizes of many plate fins arranged horizontally on the side surface of a strut be smaller in the lower part. CONSTITUTION:An aluminum heat sink 7 is bonded to the upper surface of a chip mounting board 2 by using heat sink fixing material. As to the heat sink 7, a strut is stood in the central part, and many plate type fins 7a are fixed horizontally to the periphery of the strut. The sizes of the plate fins 7a are smaller in the lower part. Hence, as to the air sent from a fan, the quantity of escaping air toward above the heat sink 7 is decreased, and on the contrary, the quantity of flowing air through the fin gaps of the heat sink 7 is increased. As the result, the practical air flow velocity in the fin gaps becomes large as compared with the conventional. heat sink 7 whose fin size is equal, so that the heat dissipation efficiency is increased.
