Embodiment 1

[0017] Such as figure 1 As shown, the present invention provides an energy storage electric heater. The new energy storage electric heater includes a housing 01 and a plurality of airtight heat storage units 02 installed in the housing 01. The adjacent heat storage units 02 is provided with an interval space 03, and each heat storage unit 02 is provided with an electric heating assembly 04 and filled with a heat storage medium 05, and a plurality of electric heating assemblies 04 are electrically connected to each other through wires 06, and the casing 01 The bottom and the top are respectively provided with a plurality of air intake holes 07 and a plurality of exhaust holes 08 . Further, the heat storage medium 05 is a phase-change molten salt, the outer surface of the electric heating component 04 and the inner surface of the heat storage unit 02 are provided with an electrically insulating and heat-conducting material layer, and a plurality of airtight heat storage units 02...

Embodiment 2

[0021] The same parts of the energy storage electric heater disclosed in this embodiment as in Embodiment 1 will not be repeated here, the difference is that a plurality of airtight heat storage units 02 can be distributed in parallel on the side of the casing 01 .

Abstract

The invention discloses an energy storage electric heater. The energy storage electric heater comprises a shell, and multiple closed heat storage units mounted in the shell; partition spaces are formed between the adjacent heat storage spaces; each heat storage unit is provided with an electric heating module inside and filled with a heat storage medium; the multiple electric heating modules are electrically connected through leads; and multiple intake holes and multiple exhaust holes are respectively formed in the bottom and the top of the shell. The energy storage electric heater uses phase change molten salt as the heat storage mediums; on the one hand, the phase change molten salt is high in enthalpy value and density, and is fast in heat conduction; and on the other hand, as the phase change of the phase change molten salt can be used for realizing molten latent heat and sensible heat combined heat storage process or heat release process, for the same heating space, the electric load is lower, the heat is higher, the heating is faster, the equipment size is smaller, and the weight is lighter.

Description

technical field [0001] The invention relates to the technical field of electric heaters, in particular to an energy storage electric heater. Background technique [0002] In order to reduce energy consumption and facilitate use, heat storage electric heaters have been developed. The Chinese patent document with the publication number CN2692544Y discloses a heat storage electric heater. The heat storage electric heater is mainly composed of a box body, a heat storage body, an insulation layer, and an electric heating tube. The electric heating tube is installed in the heat storage body. . When the power consumption is low, the electric heating tube works to heat the heat storage body, and the heat storage body stores heat. When the power consumption peaks, the electric heating tube does not work, and the heat storage body that has stored heat dissipates heat to the outside to achieve the purpose of heating. However, the existing energy storage electric heaters generally use...
