Abstract

The invention provides a phase change heat storage material and a heat storage device, relates to the technical field of new energy and energy-saving materials, and specifically belongs to a heat storage material and an application device. The phase change heat storage material is prepared from the following raw materials in parts by mass: 70 to 90 parts of sodium acetate trihydrate, 5 to 10 partsof sodium pyrophosphate decahydrate, 5 to 10 parts of sodium hydrogen phosphate dodecahydrate, 1 to 5 parts of sodium borate decahydrate, 1 to 5 parts of Nanmeizi powder, 1 to 5 parts of gelatin and1 to 5 parts of graphite. According to the invention, by optimizing the component proportion of the composite phase-change heat storage material and introducing the solid water agent, the problem of loss of crystal water is solved, aging of the phase-change heat storage material is avoided, and the heat conduction capacity is improved; and the heat storage device comprises a function cylinder assembly and a heat preservation cylinder assembly, the structure can further avoid the defects of aging, corrosion and the like of the phase change heat storage material while the heat exchange efficiency is improved, and combination, connection and customization of all layers of heat exchange pipes can be conducted according to different powers and purposes.

Description

technical field [0001] The invention relates to the technical field of new energy and energy-saving materials, and more specifically belongs to a heat storage material and an application device. Background technique [0002] Clean heating in the north generally adopts the scheme of replacing coal with electricity and replacing coal with gas, but the investment is large, the cost is high, and the local solar energy resources are wasted. The heat collector tube has been used as a heating equipment. Provide heat energy, in addition, the ambient temperature is low, the system dissipates heat, and the available heat is less. It is necessary to study a material and device that can store heat in summer and use it in winter, which can solve the problem of heat in summer and heating in winter. Phase change heat storage materials have become a better heating energy storage solution because they can store a large amount of heat energy. [0003] Under certain conditions (temperature, ...
