A cooling unit includes a heat radiant having a heat radiating plate contacting a heating element, and a plurality of heat radiation pins protruding from the heat radiating plate and separated from each other with predetermined intervals therebetween, and formed of an electrical insulating material; and an ionic wind generating unit comprising a corona emitter electrode contacting at least one of the heat radiation pins, a collector electrode facing the corona emitter electrode, and a power unit to connect the corona emitter electrode to the collector electrode and to apply a high voltage to the corona emitter electrode. Thus, the corona emitter electrode and the collector electrode of the ionic wind generating unit may be directly attached to the heat radiant, and a small and light cooling unit may be formed.
