<p>A condenser of a household laundry dryer, designed as a heat exchanger, comprises a duct (1) for the circuit of the primary medium - i.e. air, which flows around laundry to dry it - which is executed as one pipe (11) at least, yet preferentially as several pipes with a geometrically simple cross-section, which are running at an interspace (2) and preferably parallel, and a duct (3) for the circuit of the secondary medium to cool the primary one, which is executed crosswise to the duct (1) and with the interspace (2). The duct (3) is executed of a porous structure made of metal or plastic material and preferably according to extrusion procedures, where the plastic applied as a duct (3) building material is coated by metal deposition.</p> |
