The invention discloses a heating film. The heating film comprises a base material layer; the electric conductor layer is stacked on the base material layer, the electric conductor layer comprises a plurality of conductive sections, the conductive sections are connected in parallel, and the resistance values of the conductive sections are consistent; the power supply is electrically connected with each conductive section; the conductive section comprises at least one conductive unit section, and the plurality of conductive unit sections are sequentially connected in series to be electrically connected with a power supply under the condition that the plurality of conductive unit sections are arranged in the conductive section. Therefore, the resistance values of the conductive sections are consistent, and the conductive sections are connected in parallel with the power supply, so that the heating power of the conductive sections is consistent during electrification. In conclusion, according to the layout mode that the heating film is divided into the multiple conductive unit sections, and the conductive unit sections are recombined into the multiple conductive sections with the same resistance value, the heating uniformity of the heating film can be guaranteed, and the defect of local overheating caused by uneven heating is avoided.
本申请公开一种加热膜,包括:基材层;电导体层,电导体层叠置于基材层,电导体层包括多个导电段,各导电段并联,各导电段的电阻值一致;电源,电源分别电连接各导电段;导电段包括至少一个导电单元段,在导电段中设置多个导电单元段的情况下,多个导电单元段依次串联,以电连接电源。可以看出,由于各导电段的电阻值一致,并且与电源并联,故通电时,各导电段的发热功率一致。综上,此种将加热膜分隔成多个导电单元段,并将导电单元段重组为多个阻值一致的导电段的布局方式,能够保证加热膜发热的均匀性,避免加热不均导致局部过热的缺陷,本申请还公开一种加热玻璃及车辆。
