摘要

Ventilated evaporator for an automatic defrost refrigerating appliance comprising a heat-exchange surface located in a forced air flow and housed in a box-like frame (11) provided with inlet and outlet apertures (12, 13) for said forced air. The heat-exchange surface consists of only one refrigerant fluid feeding pipe shaped with a plurality of coils (15-17) which are hydraulically connected in series and arranged successively with their relevant axes transverse to the direction of flow of said forced air inside the box-like frame (11).
