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.

Abstract: Disclosed is an evaporator, comprising: a heating tube left as an empty space between first and second case sheets, which form an evaporator case, so as not to be overlapped with a cooling tube, and forming a heating passage in which a working liquid for defrosting flows; and a heater attached to the outer surface, which corresponds to the heating tube, of the evaporator case so as to heat the working liquid inside the heating tube. The heating tube can have a structure which an inlet and an outlet are respectively formed at both sides of a heater attachment part in the longitudinal direction and both end portions of a passage part are respectively connected to the inlet and the outlet, or can have a structure in which an opening is formed at one side of the heater attachment part, the working liquid heated by the heater is discharged through the opening, and the cooled working liquid is returned. The structures can form the heating passage, enabling the working liquid to circulate therethrough, without forming the inlet and the outlet, which are respectively connected to both end portions of the passage part, to be parallel at one side of the heater attachment part.

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: An evaporator comprises: 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.
