This utility model discloses an electric defrosting air cooler with de-icing function, relating to the field of electric defrosting air coolers. The utility model includes a main body of the air cooler, a fan mounting ring, a fin assembly, and a heating element disposed within the main body. A refrigerant tube, made of stainless steel, is inserted into the fin assembly with a hole spacing of 38.1 mm and a row spacing of 33 mm. The liquid inlet end of the refrigerant tube is connected to a capillary distributor, and the liquid outlet end is connected to a return gas pipe. This utility model optimizes the uniformity of refrigerant distribution through a multi-path arrangement of four inlets / four outlets and three inlets / three outlets. With four inlets / four outlets, the total pipe length of 58.8 m covers a larger heat dissipation area, increasing the cooling capacity to 7 kW, suitable for high-load scenarios. With three inlets / three outlets, the pipe length is shortened to 44.1 m, reducing flow resistance and adapting the cooling capacity to small and medium-sized needs. The precise diversion by the capillary distributor solves the problem of uneven refrigerant distribution caused by traditional single-path liquid inlet, avoiding localized frost formation or incomplete evaporation, and improving overall heat exchange efficiency.
