ABSTRACT:
A refrigerator for improving a cooling efficiency. The refrigerator has a cabinet having a refrigerating chamber, a freezing chamber, and an evaporator chamber which is disposed at a rear portion of the freezing chamber, an evaporators which generates a chilled air and has a helical shape forming a conical space portion therein, a blower assembly coaxially disposed at a rear of the evaporator so as to blow an air towards the evaporator, and a heater installed in the conical space portion of the evaporator so as to remove a frost adhering to the evaporator. The refrigerator can effectively make a heat-exchange between the evaporator and the air so that the cooling efficiency is improved. Since the turbulent air flow is introduced into the freezing chamber, the freezing chamber can be uniformly cooled and since the heater is coaxially disposed in the evaporator, the heater can uniformly heat the evaporator, so the defrosting a frost from the evaporator is effectively carried out.
