Condensing type clothes dryer and air-cooled condenser thereof

摘要

A condenser (30) of a condensing-type clothes dryer is disclosed, which includes a plurality of condensing ducts (30a) provided in a middle portion of a circulation duct, the condensing ducts (30a) condensing air (I) being circulated there-through after being discharged from a drum; and a plurality of cooling fins (30b;30c;30d;30e;30f;30g) provided to be in contact with an outer surface of the condensing ducts (30a), wherein an interval or a pitch of the cooling fins (30b;30c;30d;30e;30f;30g) is different partially according to flow rate of air blown from a cooling fan (50) for a heat-exchange with air flowing through the condensing duct (30a). At this time, the pitch or interval of the cooling fins (30b;30c;30d;30e;30f;30g) is narrow at a portion where air blown from the cooling fan (50) flows fast, and the pitch or internal of the cooling fins (30b;30c;30d;30e;30f;30g) is wide at a portion where air blown from the cooling fan (50) flows slowly.
