Pin fin die radiator

摘要

PURPOSE: To contrive to improve the heat dissipation efficiency of a pint fin radiator with cooling use axial-flow fans provided in its upper part by a method wherein a cooling air leakage is prevented from being generated from the vicinities of the upper ends of pin fins. ;CONSTITUTION: In a pin fin radiator with axial-flow fans provided abuttingly to the upper ends of pin fins, pin fins covered with a straightening plate 11 are used as outer peripheral part pin fins 12 in the vicinities of the upper ends of the pin fins. Or pin fins with a sectional area made larger the sectional area in the vicinities of the upper ends of the pin fins 12 than the sectional area of the parts between the middle parts and the lower ends of the pin fins 12 are used as the pin fins 12.;COPYRIGHT: (C)1996,JPO
