Problems solved by technology

Such frost can lead to a reduction in the cooling efficiency of the evaporator and can be inconvenient since natural defrosting must be performed for a predetermined period of time after the compressor has been forcibly turned off for defrosting

Abstract

The present invention discloses an evaporator comprising: a case formed in an empty box shape and forming a storage compartment within; a cooling tube formed in a preset pattern on the case and filled therein with refrigerant for cooling; a heating tube formed in a preset pattern on the case so as not to overlap the cooling tube, and filled therein with working fluid for defrosting; and a heating unit attached to an outer surface of the case corresponding to the heating tube, and configured to heat the working fluid inside the heating tube.

Description

technical field [0001] The present disclosure relates to an evaporator including a defrosting device for removing formed frost and a refrigerator having the same. Background technique [0002] A refrigerator is an apparatus that includes a compressor, a condenser, an expansion valve, and an evaporator and keeps various foods fresh for a long time using heat transfer according to phase change of refrigerant. [0003] The freezing method of the refrigerator can be divided into direct freezing and indirect freezing. The direct freezing method is used to cool the inside of the storage room by natural convection of cool air through the evaporator, and the indirect freezing is used to cool the inside of the storage room by forcibly circulating cool air with a cooling fan. [0004] Generally, a roll-bond type evaporator has been adopted and used in a direct-freezing refrigerator, by pressure-welding two casing sheets with an insulating member interposed therebetween and by blowing...
