Abstract: A defrosting device includes a heating unit filled with a working fluid and including an active heating part heated to a first temperature that can evaporate the working fluid, and a passive heating part positioned at a rear side of the active heating part and heated to a lower temperature than the first temperature. The defrosting device also includes a heat pipe disposed adjacent to an evaporator to transfer heat to the evaporator while circulating working fluid heated by the active heating part, the heat pipe including an entrance portion configured to receive working fluid evaporated by the active heating part, and a return portion connected adjacent to the passive heating part and configured to receive working fluid that has condensed after circulating through the heat pipe. Condensed working fluid received at the heating unit first passes through the passive heating part before being reheated at the active heating part.

Abstract translation: 除霜装置包括填充有工作流体的加热单元，并且包括被加热到能够蒸发工作流体的第一温度的主动加热部件，以及位于主动加热部件的后侧的被动加热部件，并被加热到较低温度 温度高于第一温度。 除霜装置还包括与蒸发器相邻设置的热管，用于将热量传递到蒸发器，同时循环由主动加热部件加热的工作流体，该热管包括构造成接收由​​主动加热部件蒸发的工作流体的入口部分，以及 与所述被动加热部相邻地连接并构成为接收在通过所述热管循环后冷凝的工作流体的返回部。 在加热单元处接收的冷凝工作流体首先在主动加热部件再次加热之前通过被动加热部件。
