A heat exchanger is provided to make the efficient defrost possible by preventing the degradation of the heat exchange efficiency. A heat exchanger comprises: a plurality of fins(13) arranged to be separated each other; a tube(11) installed through the fin and in which refrigerant flows; and a carbon nano tube heater(15) sparsely located between fins in order to remove the frost from a surface of the fin. The carbon nano tube heater has a contact unit in order to increase the tact area with tube. The fin has a plurality of through holes(14). |
