Abstract: Provided are a refrigerator and a refrigerator evaporator, in which a frost-inducing member is provided between an evaporator and a defrosting heater for improving heat-exchange efficiency of the evaporator and reducing defrosting time. The refrigerator includes a main body including a storage space. A heat exchange chamber is disposed inside the main body to accommodate an evaporator for generating cooling air to be circulated between the heat exchange chamber and the storage space. A defrosting heater is disposed beside the evaporator to generate heat for defrosting. A frost-inducing member is disposed at an oblique angle between the heat exchange chamber and an inlet through which cooling air returns to the heat exchange chamber, so as to induce frost formed by moisture contained in the returning cooling air. Therefore, the evaporator can have high efficiency, and power consumption can be reduced owing to a short defrosting time.
