HEAT SINK STRUCTURE AND LIGHT EMITTING DEVICE INCLUDING THE SAME

摘要

The present invention relates to a radiation structure. The radiation structure includes an element installation part; and a radiation body vertically and sequentially forming a refrigerant storage area, placed in an upper part of the element installation part and storing a refrigerant, an evaporation area in which the gasified refrigerant rises, and a condensation area in which the gasified refrigerant is condensed. The radiation body is coated with a hydrophobic material.
