Abstract (en)
[origin: EP2322708A2] The household appliance (1) such as condensation dryer, comprises a heat-exchanger (5) that is constructed with a heat-conductive material, which contains a thermoplastic plastic, and a drying chamber for objects to be dried, a process air channel (2) through which process air is guidable through the drying chamber in which a heater stands itself for heating the process air, a blower (6) for the production of the process air, and a heat exchanger for cooling the process air towards passage through the drying chamber. The material is a composite material. The household appliance (1) such as condensation dryer, comprises a heat-exchanger (5) that is constructed with a heat-conductive material, which contains a thermoplastic plastic, and a drying chamber for objects to be dried, a process air channel (2) through which process air is guidable through the drying chamber in which a heater stands itself for heating the process air, a blower (6) for the production of the process air, and a heat exchanger for cooling the process air towards passage through the drying chamber. The material is a composite material, which contains the thermoplastic plastic and/or carbon nanotubes (CNTs). The plastic consists of polyolefins, olefin copolymers and styrene copolymers, is a polypropylene or acrylonitrile-butadiene-styrene-copolymer. The composite material consists of CNTs in a quantity of 0.8-8 wt.% based on the composite material. The carbon nanotubes are multi-walled, and are obtained by deposition from the vapor phase in the catalytic decomposition of hydrocarbons (CVD). The composite material is obtained by dispersing the carbon nanotubes in thermoplastic plastic in the presence of a dispersing agent. An independent claim is included for a heat-exchanger.
