Heating device for heating surface area of object e.g. seat of motor car, has aerator for supplying airflow to surface area, where device exhibits stage in which device is switched on for heating area and aerator is activated

摘要

The device (20) has an aerator (200) for supplying an airflow to a surface area of an object (2), where the device exhibits an operating stage in which the device is switched on for heating the surface area and the aerator is activated for supporting heat transport to the surface area in a support mode. A heating resistor is arranged parallel to the surface area, where capacity of the aerator is greater than 5 percent of maximum capacity in the support mode. The aerator comprises an air conveyor (21) and an air interchange device with an air conducting layer (2221).
