Abstract: A defrosting device includes a heating unit filled with a working fluid and including an active heating part heated to a first temperature that can evaporate the working fluid, and a passive heating part positioned at a rear side of the active heating part and heated to a lower temperature than the first temperature. The defrosting device also includes a heat pipe disposed adjacent to an evaporator to transfer heat to the evaporator while circulating working fluid heated by the active heating part, the heat pipe including an entrance portion configured to receive working fluid evaporated by the active heating part, and a return portion connected adjacent to the passive heating part and configured to receive working fluid that has condensed after circulating through the heat pipe. Condensed working fluid received at the heating unit first passes through the passive heating part before being reheated at the active heating part.

Abstract: A refrigerator includes a cabinet that defines a freezing compartment and a refrigerating compartment, and an evaporator installed in the freezing compartment. The evaporator includes: an evaporator case that defines a food storage space formed therein; a cooling tube located at the evaporator case in a predetermined pattern and configured to receive a coolant; and a sheath heater disposed outside of the evaporator case to be adjacent to at least one surface of the evaporator case, the sheath heater being configured to generate heat such that heat for defrosting is transferred to the evaporator case. The sheath heater reduces the defrosting time to maintain the freshness of food, increases the cooling efficiency, and reduces power consumption. The defrosting efficiency by the sheath heater is improved by a reflection member, and an inflow of heat, generated when defrosting, into the refrigerating compartment is reduced by a heat insulation member.

Abstract: An evaporator includes: an evaporator case that defines a food storage space therein; a cooling tube located at the evaporator case and filled with refrigerant; a foil heater attached to at least one surface of the evaporator case and configured to contact the evaporator case and to generate heat such that heat for defrosting is transferred to the evaporator case. A defrosting time is reduced in comparison to that of conventional natural defrosting, such that the freshness of food can be maintained, and the cooling efficiency, having been reduced by frost, is increased such that power consumption can be reduced. The foil heater is attached to a conventional roll-bond type evaporator case, and the present invention has an advantageous effect of facilitating the maintenance of the foil heater because of a structure in which the foil heater is attached to the evaporator case.
