1. A cooling device for an electronic equipment, comprising:
an intake port comprising a fan and configured to introduce air;
a heat sink configured to dissipate heat generated from the electronic equipment by allowing air introduced from the intake port to pass between a plurality of fins;
a branch wall disposed downstream in a flow of the air across the plurality of fins of the heat sink in a manner of being orthogonal to a longitudinal direction of the fins, and configured to branch a flow of air passing between the plurality of fins into two different directions;
a plurality of ribs that have two different types of forms alternately arranged, each rib being a plate-like member disposed from the branch wall toward the fins in a parallel manner to the fins and comprising an apex portion at a tip end thereof, the plurality of ribs being configured to branch, at the tip end, the flow of air passing between the fins into two different directions, the tip end of the rib being inserted between adjacent ones among the fins, a base of each rib being connected to the branch wall; and
an exhaust port configured to exhaust the air branched by the rib and the branch wall, wherein
among the ribs alternately inserted between the adjacent fins, at least ribs of one form are in contact with the fins.
