The utility model discloses a defroster for an air-cooled refrigerator and an air-cooled freezer, which is in a plate shape with a multilayer structure and comprises a substrate, a printed circuit layer positioned on the substrate and a first insulating layer coated on the upper surface of the printed circuit layer. According to the defroster for the air-cooled refrigerator and the freezer, the plate-shaped structure of the printed circuit is adopted, heating wires are not included, and the risk of explosion after refrigerant leakage does not exist; and magnesium oxide does not need to be filled, the specific heat capacity is low, the defroster quickly stops continuously dissipating heat into the refrigerator when being powered off, and the energy consumption is low. 本实用新型公开了一种风冷冰箱、冰柜用除霜器，所述除霜器为具有多层结构的板状，包括基板、位于所述基板之上的印刷电路层和涂覆在所述印刷电路层上表面的第一绝缘层。本实用新型的风冷冰箱、冰柜用除霜器采用印刷电路的板状结构，不含加热丝，不存在制冷剂泄漏后爆炸的风险；不需要充填氧化镁，比热容低，除霜器断电就很快停止向冰箱中继续散发热量，能耗低。
