Description

Technical Field

[0001] This utility model relates to the field of heating wire connection technology, specifically to a heating wire connection mechanism inside a solid heat storage device. Background Technology

[0002] Solid-state electric thermal energy storage devices are used to store off-peak electricity as heat. When needed, the heat is extracted through a heat exchanger for industrial and civil use, such as industrial and civil heating, equipment heating, etc., to achieve the purpose of rational use and energy saving, reducing production costs, reducing harmful gas emissions from traditional heating, and reducing environmental pollution. In the process of thermal energy storage, electrical energy is stored after generating heat through heating wires.
