An electric heating device comprises a housing with a partition wall which separates a connection chamber from a heating chamber for dissipating heat and from which at least one PTC heating device protrudes as a heating fin in the direction toward the heating chamber. The PTC heating device comprises at least one PTC element and conductor tracks electrically connected to the PTC element for energizing the PTC element with different polarity, which are connected electrically in the connection chamber. In addition, a temperature sensor is provided as part of the electric heating device, which is connected, in terms of data, to a control device and is accommodated in a sealed manner in a temperature sensor receptacle which is formed in a wall delimiting the heating chamber. To improve accomodation of the temperature sensor and contact in the connection side thereof, the temperature sensor is accommodated in a sliding manner in the temperature sensor receptacle; a support, copperating with the temperature sensor prevents the temperature sensor from sliding out of the temperature sensor receptacle; a temperature sensor contact element of the temperature sensor in the connection chamber is plugged into a printed circuit board arranged in the connection chamber.
电加热装置包括具有将连接室与加热室分离以散热的分隔壁的壳体,至少一个PTC加热装置作为加热翼片在朝加热室的方向上从分隔壁突出,PTC加热装置包括至少一个PTC元件和电连接到PTC元件的以不同极性给PTC元件通电的导电带,导电带在连接室中被电连接,电加热装置具有与控制装置在数据上连接并以密封方式容纳在温度传感器容器中的温度传感器,温度传感器容器形成在界定加热室的壁中。为改善温度传感器的容纳和在其连接侧上的接触,本发明提出温度传感器以滑动方式容纳在温度传感器容器中;设置与温度传感器配合的防止温度传感器从温度传感器容器滑出的支撑件;将温度传感器的在连接室中的温度传感器接触元件直接插接到布置在连接室中的印刷电路板中。
