Complex type fan and heat dissipation device provided with the fan

摘要

An object of the present invention is to provide a structure of heat dissipation device using a heat dissipation effect is high complex type fan and the fan. Consists A hub 110 and a plurality of blades 150, a composite-type fan for cooling the heat source, the hub will androgynous opposing first side 120 and second side 130, each of blades are arranged distributed on the outer peripheral surface 140 of the hub, and includes a one second portion 170 which connects the first portion 160 and a first portion extending from the hub, the first side surface or the second respective second portion hub They arranged to protrude from the side surface, a plurality of streaky structure and made of a soft material. Can be placed in close proximity to the surface of the heat source by streak-like structure, effectively blowing, it is possible to exhaust heat.FIELD 1
