Heater assembly and vehicle

Technical Field

The utility model relates to the technical field of heating, in particular to a heater assembly, a heater assembly and a vehicle.

Background

In the prior art, the ceramic heater can be applied to a vehicle, and after the ceramic sheet group is electrified, electric energy can be converted into heat energy and is transmitted out from the shell, so that air or water is heated, and finally, the temperature in the passenger cabin is adjusted.

The inventor researches find that the ceramic heater in the prior art has the following defects in the use process:

referring to fig. 1, the ceramic heater has planar contacts between the insulating papers 001, the insulating papers 001 and the conductive sheets 002, and the insulating yellow papers 001 and the casing 003, and after the assembly, part of air is enclosed between the insulating papers, the insulating papers and the conductive sheets, and between the insulating yellow papers and the casing, thereby forming a plurality of air bubbles.
