Cooling unit using ionic wind and LED lighting unit including the cooling unit

摘要

A cooling unit (100) includes a heat radiant having a heat radiating plate (111) contacting a heating element (H), and a plurality of heat radiation pins (112) protruding from the heat radiating plate (111) and separated from each other with predetermined intervals therebetween, and formed of an electrical insulating material; and an ionic wind generating unit (120) comprising a corona emitter electrode (121) contacting at least one of the heat radiation pins (112), a collector electrode (122) facing the corona emitter electrode (121), and a power unit (123) to connect the corona emitter electrode (121) to the collector electrode (122) and to apply a high voltage to the corona emitter electrode (121). Thus, the corona emitter electrode (121) and the collector electrode (122) of the ionic wind generating unit (120) may be directly attached to the heat radiant, and a small and light cooling unit (100) may be formed.
