Heat energy storage element

Abstract

The invention relates to an energy storage element, in particular to a heat energy storage element which makes use of electric heating to store energy for a solid. The heat energy storage element comprises a shell, wherein a heating pipe is arranged in the shell, the two ends of the heating pipe are fixed on end covers at the two ends of the shell, the middle parts of the end covers at the two ends of the shell are provided with ceramic insulating stools, the centers of the ceramic insulating stools are provided with electrodes which are connected with the heating pipe, a ceramic bracket is arranged in the shell and is sleeved on the heating pipe, and a solid heat storage body is arranged in a hollow cavity formed by the shell, the ceramic bracket and the heating pipe. The heat energy storage element has the advantages that the volume of the energy storage element can be adjusted according to the capacity of the stored energy, or a plurality of energy storage elements are overlapped; and the maintainability of a single energy storage element is good, the group number of the heat storage capacity can be adjusted at random, and the solid heat storage body can improve the heating temperature to change more electric energy into heat energy to be stored.

Description

technical field [0001] The invention relates to an energy storage element, in particular to a thermal energy storage element which uses electric heating to store energy in solids. Background technique [0002] The energy shortage in today's society has caused the price of resource products to rise rapidly. The heat energy provided by heating companies is realized by coal, but the rising coal price has brought huge pressure to heating companies, and finally turned the rising pressure to user. The problem of power supply is also very prominent. The production-type and residential power consumption make the power consumption peak during the day, and the power is often cut off during the day, but the power consumption drops sharply in the middle of the night, and the power consumption during the day and night is in sharp contrast. , so the country encourages the use of electricity at night. Therefore, heating equipment using electric heating has appeared, and energy storage is...

Problems solved by technology

But the current energy storage boiler uses water as the carrier of energy storage, but the limitation of water is large, the water can only be heated to below 90 ℃, and the heating resistance wire in the water has high requirements, and electric leakage must be prevented, and insulation is also required. Small energy and large size limit the promotion and use of large areas
