HEAT EXCHANGER FOR REFRIGERATOR

摘要

PURPOSE: A heat exchanger for refrigerator is provided to decrease quantity of frost formed on a fin plate or to raise density of the frost. CONSTITUTION: A heat exchanger comprises a pair of end plates placed on both ends; a plurality of fin plates(12) layered between the end plates; and refrigerant pipes penetrating the end plates and the fin plates and fluidically connected with each other and includes extensions(12a) formed on ends of the fin plates, respectively, to generate condensed water and having hydrophilic layers formed thereon. The extensions are warm enough to convert moisture in the air into condensed water without frost formed thereon as being distant from the refrigerant pipes.
