Abstract: A defrosting apparatus includes: a heating unit including a heater case and a heater, where the heater case defines an inner flow path having an inlet and an outlet at ends thereof, and the heater is mounted in the heater case to heat a working fluid within the inner flow path; and a heat pipe inserted into the inside of the heater case through the inlet and the outlet, and which has at least a part thereof disposed to be adjacent to a cooling pipe of an evaporator such that heat is radiated to the cooling pipe of the evaporator by means of the working fluid at a high temperature that is heated by the heater and then is transferred, where the heater is configured to stop emit heat at a preset temperature or higher, since an electric current is suppressed due to a sharp increase in resistance.

Abstract: The present invention provides an evaporator comprising: an evaporator case having first and second case sheets coupled to each other and bent such that both sides of the evaporator case are open, thereby forming a box shape, a food storing space being formed inside the evaporator case; a cooling tube provided as an empty space between the first and second case sheets, thereby forming a cooling channel through which a refrigerant flows; and a heating tube formed as an empty space between the first and second case sheets so as not to overlap with the cooling tube, thereby forming a heating channel for defrosting, wherein the cooling tube and the heating tube are shaped to protrude to the outside of the evaporator case, and the evaporator case has an inner surface formed to be flat.

Abstract: A defrosting apparatus comprises a heater case comprising a heat pipe seating part formed to extend from one surface thereof in a recessed shape and a heater receiving part formed to extend to be parallel with the heat pipe seating part. The defrosting apparatus also includes a heater which is mounted in the heater receiving part so as to emit heat when power is applied thereto, a heat pipe which has a flow path through which a working fluid filled therein flows, which has a part seated on the heat pipe seating part, and which is disposed to be adjacent to a cooling pipe of an evaporator such that heat is radiated to the cooling pipe of the evaporator by means of the working fluid at a high temperature which is heated by the heater and then is transferred, and a holder which is detachably coupled to the heater case so as to cover the heat pipe seated on the heat pipe seating part.
