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.

1. A heat dissipating apparatus, comprising: a heat conducting base (1);a plurality of heat pipes (2), coupled to the heat conducting base (1) and linearly arranged along an axis; anda plurality of heat dissipating fins (3), sequentially penetrated by the plurality of heat pipes (2);wherein a pair of vortex generators (32) are installed with an interval apart on each of the heat dissipating fins (3), the pair of vortex generators (32) are disposed proximate to a side of each of the plurality of heat pipe (2) respectively, and the pair of vortex generators (32) are disposed symmetrically to each other along the axis and equally spaced from a corresponding heat pipe, each vortex generator (32) has two guiding oblique planar triangle surfaces (320), (321) protruding from a surface of the heat dissipating fin (3) and intersecting to form a ridge (L), each of the two guiding oblique planar triangle surfaces (320), (321) includes a wide end side and a narrowed end, the ridge (L) extends toward the narrowed ends of the two guiding oblique planar triangle surfaces (320), (321) to point to the side of the heat pipe (2) and ascends from the surface of the heat dissipating fin (3) in a direction from an upwind side to a downwind side, and a through hole (322) is formed by the wide end sides of the two guiding oblique planar triangle surfaces (320), (321) and penetrates through the heat dissipating fin (3), and thus the through hole (322) is formed as a triangle shape on the heat dissipating fin (3), wherein two sides of the through hole (322) are the wide end sides of the two guiding oblique planar triangle surfaces (320) and third side of the triangle through hole (322), (321) is a cutting edge of the heat dissipating fin (3) at the through hole,wherein the ridges (L) of the pair of the vortex generators (32) start from the wide end sides of the two guiding oblique planar triangle surfaces (320), (321) and extend in a direction towards the narrowed ends of the two guiding oblique planar triangle surfaces (320), (321) to form an intersection at a center of the corresponding heat pipe, andwherein the through hole (322) of each vortex generator (32) is oriented upwardly and obliquely, thereby creating Stack Effect which forces an air in a lower level heat dissipating fin (3) to go up through the through hole (322) to an upper level heat dissipating fin (3). 2. The heat dissipating apparatus with a vortex generator as recited in claim 1, wherein the heat conducting base (1) is substantially a plate. 3. The heat dissipating apparatus with a vortex generator as recited in claim 1, wherein each heat dissipating fin (3) has a penetrating hole (30) formed correspondingly thereon for allowing the heat pipe (2) to pass through. 4. The heat dissipating apparatus with a vortex generator as recited in claim 3, wherein each penetrating hole (30) has a circular flange (31) protruding from the periphery of the penetrating hole (30) for keeping a close contact with the heat pipe (2). 5. The heat dissipating apparatus with a vortex generator as recited in claim 1, wherein the two ridges (L) are intersected to produce an included angle θ of 60°. 6. The heat dissipating apparatus with a vortex generator as recited in claim 1, wherein each heat dissipating fin (3) includes a plurality of auxiliary vortex generators (5) arranged transversally on the heat dissipating fin (3). 7. The heat dissipating apparatus with a vortex generator as recited in claim 6, wherein the auxiliary vortex generators (5) are provided in pairs.
