Abstract

The invention innovatively provides a novel solid energy storage module and an electric heating solid energy storage device. The serial problems that an existing solid energy storage type electric boiler and a heat exchange structure thereof are complex in system structure, long in heat storage and release time, short in electric heating pipe service life, high in cost, complicated in maintenance and the like will be changed. By means of high heat conductivity of a special heat pipe, a heat absorption segment of the heat pipe is heated through a high-frequency induction coil, by means of heat transfer of multiple heat conduction fins on the heat pipe, a solid energy storage material body wrapping the outer portion of the heat pipe can be fast heated, and energy storage can be achieved; and during heat release, heat energy stored in the solid energy storage material body can be fast guided out. The electric heating solid energy storage device is formed by multiple solid energy storage modules, and can be used in cooperation with a heat exchanger, high-temperature steam or hot water for heating and the like can be generated, and a small domestic energy storage heater can be formed.

Description

technical field [0001] The invention belongs to the technical field of solar heat utilization, and in particular relates to a technology of a solid energy storage module and an electrothermal solid energy storage device. Background technique [0002] According to relevant data and statistics, the fundamental measure to reduce or eliminate smog is to significantly reduce the emission of major pollutants. One of the keys is to speed up the adjustment of energy structure and solve the problem of coal combustion pollution and other pollution emissions. [0003] The design and development of solid energy storage atmospheric pressure electric boilers are aimed at the replacement products of many small and medium-sized coal-fired boilers. Due to their low thermal efficiency, environmental protection and management difficulties, small and medium-sized coal-fired boilers have been widely used in developed countries and cities above medium-sized in my country. It is forbidden to use, a...
