Abstract:
1. A heat dissipating module, applied to a low-level chip for dissipating heat, comprising: a base, wherein said base has a recess for containing a fan, and a surface of said recess has a protrusion for increasing a heat dissipating area; a first fin module, comprised of a plurality of unidirectional fins; and a second fin module, comprised of a plurality of unidirectional fins: such that said first fin module is disposed separately on two corresponding ends of said base, and said second fin module is disposed within said corresponding first fin module, and said fins of said second fin module are arranged in an outwardly ascending shape, and said outwardly ascending fins allow outside air to flow into said base without being blocked, so as to increase a heat dissipating area, and said fins disposed on said second fin module and at the farthest distance from said fan are bent inward, such that when said heat dissipating module is in use, the airflow produced by said rotating fan is blocked and bounced back to an inner layer of fins by said inwardly bent fins.
