摘要： The present invention discloses a defrosting device, including: a heating unit provided at a lower portion of the evaporator; and a heat pipe connected to an inlet and an outlet of the heating unit, respectively, and having at least part thereof disposed adjacent to a cooling pipe of the evaporator such that the cooling pipe of the evaporator is cooled by a working fluid of high temperature which is transferred in a heated state by the heating unit, wherein the heating unit includes: a heater case extending in one direction to be arranged in a left and right direction of the evaporator, and having the inlet and the outlet at both sides thereof; and a heater provided with an active heating part accommodated within the heater case and actively generating heat to heat the working fluid, and a passive heating part extending from the active heating part and heated up to temperature lower than temperature of the active heating part, and wherein the inlet is formed at a position away from the active heating part to prevent the working fluid returned after flowing along the heat pipe from being introduced directly into the active heating part.
