Defroster for heat exchanger and fabrication method thereof

摘要

A defroster for a heat exchanger includes a heat transfer plate (60) on the heat exchanger; a thin film heater (70) arranged on the heat transfer plate (60); and a power supply wire (80) connected to the film heater (70) for supplying power to the film heater (70). The defroster can be fabricated by forming a masking layer with a certain shape on an electrically resistant substrate (100); patterning a thin film heater (70) on the substrate (100) based on the shape of the masking layer, adhering the film heater (70) to a heat transfer plate (60); and connecting a power supply (80) to the film heater.
