Evaporator and refrigerator having same

An evaporator comprising:

• an evaporator case having first and second case sheets coupled to each other and bent to form a storage space;
• a cooling tube provided by a first channel formed between the first and second case sheets and forming a cooling circulation path in which a refrigerant flows;
• a heating tube provided by a second channel formed between the first and second case sheets in which a working fluid flows;
• a heating chamber rovided b a s ace formed between the first and second case sheets, the heating chamber including an opening formed on a side thereof to communicate with the heating tube to form a heating circulation path through which the working fluid circulates;
• and
• a heater provided on an outer surface of the evaporator case at a position corresponding to where the heating chamber is formed to the working fluid,
• wherein the opening of the heating chamber is configured to allow the working fluid heated by the heater to be discharged and cooled working fluid to be returned therethrough.

An evaporator, comprising:

• a case having an inner layer and an outer layer;
• a first channel formed between the inner and outer layers in which a first refrigerant flows;
• a second channel formed between the inner and outer layers in which a second refrigerant flows;
• a fluid chamber communicating with the first tube;
