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: Provided is a heat exchanger. The heat exchanger includes a plurality of refrigerant tubes through which a refrigerant flows, the plurality of refrigerant tube being disposed to be spaced apart from each other in one direction and a plurality of fins disposed between the plurality of refrigerant tubes. A distance between the fins disposed on a front end-side of the plurality of refrigerant tubes is greater than that between the fins disposed on a rear end-side of the plurality of refrigerant tubes.
