Abstract

The invention discloses a novel phase change heat storage heat exchanger and a working method of the novel phase change heat storage heat exchanger. The novel phase change heat storage heat exchangercomprises a heat storage heat exchanger shell, the heat storage heat exchanger shell is internally provided with a heat insulation layer, a cavity inside the heat insulation layer is divided into an upper part and a lower part by an orifice plate, the upper part of the cavity is provided with a heat storage medium, the lower part of the cavity is provided with a heat exchange medium, the lower part of the cavity communicates with the top of the upper part of the cavity through a pipe, the pipe is provided with a circulation pump, and the cavity inside the heat insulation layer is in a vacuum state or a negative pressure state. The novel phase change heat storage heat exchanger has the beneficial effects that heat is transferred to the heat exchange medium through a heat exchange pipe or aheat pipe, the heat exchange medium is transported to the upper part of a tank through the circulation pump for atomization spraying, the medium and the heat storage medium in the tank are subjected to heat exchange, and therefore a good heat storage effect is obtained.

Description

technical field [0001] The invention relates to a novel phase-change heat storage and heat exchange technology, which is mainly used in the fields of energy and chemical industry, aerospace, military industry, air conditioning and refrigeration, and is especially suitable for occasions requiring heat storage. Background technique [0002] Heat storage technology is a technology that uses heat storage energy storage materials for energy storage. According to the heat storage method, it can be divided into sensible heat storage, phase change heat storage, thermochemical heat storage and adsorption heat storage. Compared with several other forms of heat storage, phase change heat storage refers to the storage and release of energy by utilizing the material characteristics of the heat storage medium to absorb or release a large amount of latent heat of phase change during the phase change process. In the cycle process of heat storage and energy release, the grade and use time of...
