Abstract
The present invention discloses a heat dissipating module applied to a low-level chip for dissipating the heat produced by the low-level chip. The heat dissipating module has a base, and the base accommodates a fan. The base includes first and second fin modules, and the first and second fin modules are comprised of a plurality of unidirectional fins. The first heat dissipating module is installed separately at two corresponding ends of the base, and the second fin module is disposed within the first fin module, and the fins on the second fin module are arranged in an outwardly ascending shape, and the fins at the farthest distance from the fan are bent inwardly. The invention not only allows outside air to enter into the base through the outwardly ascending fins without being blocked by the fins adjacent to the fan, but also increases the heat dissipating area.
