Abstract: PURPOSE:To provide a heat exhanger with the function of a fan casing to shorten the size of depth of the unit and permit to blow off air into three directions by a method wherein a centrifugal type fan is enclosed by the bent heat exchanger arranged from the beginning end to the ending end of a scroll plate. CONSTITUTION:A centrifugal type fan 12 is enclosed by the bent heat exchanger 13 having U-shape in the plan view thereof and arranged continuously from the ending end 14 of the scroll plate 5 to the beginning end of the same plate 5. The height of the main body 1 of the unit can be restricted to the substantially same size of the thickness of the fan casing 4, therefore, the unit may be finished to a super thin type. The heat exchanger 13 is arranged so as to enclose the fan at the blow-off side of the centrifugal type fan 12 while a dust removing air filter is provided at the suction side of the fan 12, therefore, the noise, generated by the fan 12, is intercepted by both of these parts. A high sound deadening effect may be obtained when the heat exchanger equipped with needle-type fins, whose ventilating resistance is large, is employed especially as the heat exchanger 13 of blow-off side.
