Embodiment Construction

[0037] A typical preferred embodiment of the present invention will be described in detail below.

[0038] In this embodiment, the drying device is a household clothes dryer. The clothes dryer has a drying chamber and a closed process air guide, the process air guide is integrated with the drying chamber, and in the process air guide there is a heat pump comprising a heat sink and a heat source, the heat sink The heater and heat source alternately cool and heat the circulating process air. The two heat exchangers as heat sink and heat source are preferably curved pipe systems in each case. The curved piping system is welded together by various copper pipes and bent pipes, and a cooling fin is arranged on each pipe. These fins are thin metal strips made of aluminum and are used to increase the heat exchange between the working medium flowing through the piping system and the process air flowing around the piping system. The heat sink and heat source are pre-installed in the ...

Abstract

The invention relates to a drying appliance comprising a drying chamber and a process air guide for guiding drying air through said drying chamber, said process air guide comprising a heat exchanger for cooling process air which comprises a charge of humidity and particulates, and disposed downstream of said drying chamber within said process air guide, wherein said heat exchanger is coated at least partially with a polymer coating on a part of a surface of the heat exchanger. The part of said surface below said coating has a passivating layer interposed between said coating and said surface.

Description

technical field [0001] The invention relates to a drying device, which comprises a drying chamber and a process air guiding device, the process air guiding device is used to guide drying air through the drying chamber, and the process air guiding device includes a Gas and particulate process air heat exchanger, the heat exchanger is arranged in the process air guide, and in the downstream of the drying chamber, the heat exchanger on the part of the surface of the heat exchanger at least Partially coated with polymer coating. Background technique [0002] In order to perform heat exchange efficiently, heat exchangers used in drying equipment such as household clothes dryers must meet the following requirements. First of all, the thermal conductivity of the heat exchanger body should be good. In addition, the surface of the heat exchanger exposed to any kind of dirt or dust should be easy to clean, because any kind of dirt or dust adsorbed on the surface of the heat exchanger...
