Abstract

The heat exchanger is located in the air feed stream in front of the heater, where the hot damp exhaust air also flows through. The system reduces the drying time of the clothes drier, by increasing the efficiency, through maintenance or reduction of the heating capacity. The heat exchanger is placed between the fan and the heater, and it includes a collector for condensation and a mesh to catch lint in the exhaust air flow. The heat exchanger is integrated into one unit with the heater, and is connected to the fan, and carries the drive motor for the clothes dryer.
