HEAT SINK AND FAN DEVICE USING IT

摘要

PROBLEM TO BE SOLVED: To provide a heat sink that can be reduced in pressure loss and improved in cooling efficiency, and to provide a fan device using the heat sink. SOLUTION: In the heat sink which radiates the heat generated from electronic parts D through a plurality of heat radiating fins 2 erected on a base 5 set up on the parts D, the fins 2 are arranged in orthogonal X and Y directions and the fins 2 adjoining each other in the X-direction are inclined in the direction opposite to the inclined direction of the fins 2 arranged in the Y-direction.
