The invention discloses a PTC (Positive Temperature Coefficient) electric heater for an air conditioning system of an electric vehicle, and relates to an electric heater device. The PTC electric heater for the electric automobile air conditioning system can be conveniently installed and comprises a supporting frame, a PTC electric heater body, connecting frames, a downward pressing rod and the like, the supporting frame is connected with the symmetrically-arranged connecting frames, the connecting frames are slidably connected with symmetrically-arranged fixing pieces, and the PTC electric heater body is connected with the downward pressing rod. And the connecting frame is axially connected with the lower pressing rod in a sliding manner. According to the PTC electric heater fixing device, a downward pressing rod is manually pressed down by people, so that an extrusion frame can extrude a wedge-shaped block, accordingly, fixing pieces move to apply extrusion force to storage positions in an engine compartment, the fixing pieces can be clamped through a clamping assembly, and the PTC electric heater is fixed through the extrusion force; therefore, people do not need to punch holes and rotate the screw rod to fix the PTC electric heater, so that the PTC electric heater is more convenient to install.
本发明公开了一种电动汽车空调系统用PTC电加热器,涉及电加热器装置。要解决的技术问题是:提供一种能够方便安装的电动汽车空调系统用PTC电加热器,包括有支撑架、PTC电加热器、连接架、下压杆等,所述支撑架连接有对称设置的所述连接架,所述连接架滑动式连接有对称设置的所述固定件,所述连接架轴向滑动式连接有所述下压杆。本发明通过人们手动将下压杆下压,使得挤压架能够挤压楔形块,从而使得固定件分别移动对发动机舱内的储存位置施加挤压力,且卡位组件能够将固定件位置卡位,这样通过挤压力来固定PTC电加热器,这样人们无需打孔以及旋转螺杆来固定PTC电加热器,使得安装PTC电加热器更加便捷。
