The invention relates to the technical field of automobile heat management, in particular to a multi-cavity thick film heater. The multi-cavity thick film heater comprises an upper cover, an upper water chamber, a lower water chamber, a lower cover, a PCB (Printed Circuit Board), an upper heating plate and a lower heating plate; the upper cover, the upper water chamber, the lower water chamber and the lower cover are sequentially overlapped in the thickness direction of the heater; a closed first heating cavity is defined between the upper cover and the upper water chamber, and the upper heating plate is arranged in the first heating cavity; a closed second heating cavity is defined between the lower cover and the lower water chamber, and the lower heating plate is arranged in the second heating cavity; a closed control cavity is defined between the upper water chamber and the lower water chamber, and the PCB is arranged in the control cavity; and the PCB is electrically connected with the upper heating plate and the lower heating plate respectively. Therefore, the preset heating effect can be guaranteed, meanwhile, heat accumulation is improved, and the service life of the heating plate is prolonged.

    本发明涉及汽车热管理技术领域,具体而言,涉及一种多腔厚膜加热器。多腔厚膜加热器包括上盖、上水室、下水室、下盖、PCB板、上加热板、下加热板;沿加热器的厚度方向,上盖、上水室、下水室、下盖依次叠合布置;上盖、上水室之间围合形成密闭的第一加热腔,上加热板设置在第一加热腔内;下盖、下水室之间围合形成密闭的第二加热腔,下加热板设置在第二加热腔内;上水室、下水室之间围合形成密闭的控制腔,PCB板设置在控制腔;PCB板分别与上加热板、下加热板电连接。如此能够保障预设的加热效果的同时,改善热量堆积,延长加热板的使用寿命。
