The invention relates to an electric heating device (2) which has a simple structure and is easy to change in size, having a plurality of cartridges (4) which are arranged one on top of the other, each of which is arranged on oppositely arranged front side surfaces (6; 8) has two openings (10; 12), wherein the opening (10; 12) forming an inlet and the other of the openings forming an outlet, the openings arranged therebetween being connected in pairs to deflection means (20; 22), the fluid inside the cartridge (4) being deflected by the deflection means (20; 22) is deflected from a first cartridge (4) to a second cartridge (4) adjacent to the first cartridge. A PTC heating device (5) is arranged between adjacent cartridges (4) and is coupled in a thermally conductive manner to flow channels (24; 24 ') arranged in both cartridges (4). 26).
本发明涉及一种结构简单且易于进行规模变化的电加热装置(2),所述电加热装置具有层层叠置的多个盒(4),多个盒中的每个在相反设置的正面侧表面(6;8)上具有两个开口(10;12),其中开口(10;12)中的一个形成入口,开口中的另一个形成出口,设置在之间的开口成对地连接到偏转装置(20;22),盒(4)内的流体通过偏转装置(20;22)从第一盒(4)偏转到与第一盒相邻的第二盒(4)。PTC加热装置(5)设置在相邻的盒(4)之间,并且以导热方式耦合到设置在两个盒(4)中的流动通道(24;26)。
