PLANE-TYPE HEATER WITH HOT WIRES, WHICH ARE ARRANGED DENSELY

摘要

PURPOSE: A plane-type heater is provided to equalize a defrost operation for each part of an evaporator and to improve defrost efficiency of the evaporator by concentrating heat of a heater at a cold air inlet unit of the evaporator by disposing densely hot wires. CONSTITUTION: In a plane-type heater(365) for defrosting by applying equally heat generated by a heating action of a hot wire(367) on front/rear sides of an evaporator(360), the hot wires of the plane-type heater positioned at a cold air inlet unit(A') are arranged denser than the hot wires positioned outside of the cold air inlet unit to concentrate heat of the heater on the cold air inlet unit being a predetermined area of the evaporator moving in the cold air along the flow direction of the cold air.
