Abstract: A radiator according to one embodiment of the present invention comprises at least one group of heat dissipation layers that are applied to the surface of the radiator so as to be sequentially layered thereon, wherein the one group of heat dissipation layer comprises a first coating layer formed by applying either a first dispersion solution or a second dispersion solution, and a second coating layer formed by applying the dispersion solution differing from that on the first coating layer, the first dispersion solution comprises positively charged metal oxide nanoparticles, and the second dispersion solution comprises negatively charged carbon nanotubes (CNT-COOH). The heat dissipation layer is formed in a porous thin film structure so as to have thickness of several micrometers, and thus increases a heat dissipation area by ten times, thereby improving heat dissipation efficiency, and can be applied without being restricted by the size, volume, shape, arrangement and the like of a radiator.

Abstract: Disclosed are an ion generating device and an air conditioner having the same. The air conditioner may include a housing; a blower which causes a flow of air passing through an inner space of the housing; a heat exchanger located in the inner space of the housing; and an ion generating device which is spaced apart from the heat exchanger, and coupled to an inner side of the housing, wherein the ion generating device may include: a hollow body; a fan which is coupled to one side of the body, and causes a flow of air passing through an inside of the body; and an ionizer which is coupled to the other side of the body, and generates ion, wherein the ionizer may include a case hole which is formed in a portion of the ionizer facing the inside of the body, and communicates with the inside of the body.
