Phase-change heat-storage electrical heater

Abstract

The invention discloses a phase transition heat storage electronic heater; an electric heating tube is mounted on the bottom of the irradiator shell; the phase transition heat storage agent is filled in the upper part of the irradiator shell; when the electric heating tube is electrified to operate, the phase transition heat storage agent absorbs heat energy to become the fluid state from the solid state, supplies heat energy through the irradiating fins of the irradiator and storage and stores part of the heat quantity in the phase transition latent heat mode. When the electric heating tube is powerdown and stopped from being heated, the phase transition heat storage agent releases the stored latent heat to become the solid state from the liquid state and supplies heat energy continuously through the channel pipe and the irradiating fins of the irradiator. The power energy is saved through the frequent electrification and powerdown while the sustainable heating of the phase transition heat storage electronic heater is guaranteed.

Description

Technical field [0001] The invention relates to the technology in the field of heating equipment, in particular to a phase-change heat storage electric heater composed of a radiator shell, a channel pipe, a heat sink, an electric heating tube, a phase-change heat storage agent, and the like. Background technique [0002] In the prior art, electric heating devices have been widely used, the most common electric heating oil heater, which is in the housing of the electric heating oil heater, and packs heat-conducting medium oil and an electric heater. When in use, the electric heater is energized to generate heat, heats the heat conduction medium oil, and achieves the purpose of heating through the heat dissipation of the shell. Although this kind of electric heating oil tank can generate heat for heating when it is powered on, after the power is turned off, because the heat transfer medium oil has a small specific gravity and a poor heat storage capacity, it cools down quickly...

AI Technical Summary

Problems solved by technology

[0003] The task of the present invention is to provide a phase-change heat storage electric heater, which can effectively overcome the shortcomings of the prior art products that cannot provide heating for a long time after power failure, and can provide heat and heating for a long time after power failure to achieve energy-saving effect
