Heat exchanger for dryer and condensing type dryer using the same

摘要

A heat exchanger (30) for a dryer includes a core in which a plurality of tube units (32) and a plurality of fin units (34) are alternately stacked. Front and rear covers (40,42) are attached at front and rear sides of the core. A front plate (50) is positioned between the core and the front cover and a rear plate (50) is positioned between the core and the rear cover. The plates (50) have openings (52) at locations corresponding to the opened ends of the tube units(32). The plates (50) are physically coupled with the front and rear covers (40,42). The plates (50) are also attached to the core with a cladding material by a brazing operation.
