Heating device

The invention relates to the technical field of heating equipment, in particular to a heater which comprises a storage part, a heating part, heat dissipation fins and a pressurization assembly, and a heating medium is stored in the storage part; the heating element is arranged in the storage part; the heat dissipation fins are arranged in the circumferential direction of the storage part, and the tops and the bottoms of the heat dissipation fins communicate with the top and the bottom of the storage part correspondingly; the pressurizing assembly is arranged in the storage part so as to drive the heating medium to circularly flow between the storage part and the radiator fins. According to the radiator fin, the heating medium in the storage part can be subjected to distributed heat dissipation, the heat dissipation area of the heater is increased, the pressurization assembly promotes the heating medium to circularly flow between the radiator fin and the storage part, the heat transfer rate is increased, and t
