Abstract
A heat dissipating apparatus with a vortex generator includes a heat conducting base, a heat pipe, and a plurality of heat dissipating fins. Each heat dissipating fin has a pair of vortex generators installed with an interval apart and disposed adjacent to a side of the heat pipe, and each vortex generator has two guiding oblique surfaces protruding from a surface of the heat dissipating fin, and the two guiding oblique surfaces protrude in a tapered form. A through hole is formed at a wide position of the tapered form and penetrates through the heat dissipating fin, such that the vortex generators of each heat dissipating fin induce a stack effect at corresponding upper and lower part of the heat dissipating fin to improve the heat dissipating efficiency.
