▎ 摘　　要

NOVELTY - The utility model claims a seat heating device, a heating seat and a vehicle, the seat heating device comprises a surface layer, a heating layer and a heat reflecting layer, the heating layer is set between the surface layer and the reflecting layer, the heating layer is graphene carbon material. The technical solution of the utility model uses graphene carbon material instead of resistance wire heating mode, through Brown motion heating, has very high unit electric quantity of heat conversion rate, solves the problem that the electric energy utilization rate is low and the energy consumption is high. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) a heating seat; (2) a vehicle.
