Novel heat accumulator based on phase-change heat accumulation materials

Abstract

The invention discloses a novel heat accumulator based on phase-change heat accumulation materials. The novel heat accumulator comprises a box; a plurality of heat exchange boards are arranged inside the box; a plurality of cavities are formed among the heat exchange boards as well as among the heat exchange boards and the box; every two adjacent cavities are the heat exchange fluid cavity and the heat accumulation cavity respectively; every two adjacent heat exchange fluid cavities communicate with each other through a first pipeline; the heat exchange fluid cavities and the first pipelines are filled with heat exchange fluid; every two adjacent heat accumulation cavities communicate with each other through a second pipeline; the heat accumulation cavities and the second pipelines are filled with the phase-change heat accumulation materials; and the phase-change heat accumulation materials and the heat exchange fluid carry out heat exchange. An independent heat accumulation system and an independent heat exchange system are formed inside the box and operate jointly to complete the heat release and heat accumulation functions of the heat accumulator, the structure is compact and simple, the novel heat accumulator is convenient to carry and easy to dismount and mount, the phase-change heat accumulation materials inside the heat accumulation system can be replaced according to use demands, the application range is wide, the novel heat accumulator is suitable for recycling waste heat in daily life for people, and energy conservation and environmental protection are achieved to a greater extent.

Description

Technical field: [0001] The invention relates to the technical field of thermal storage equipment, in particular to a novel thermal storage device based on phase-change thermal storage materials. Background technique: [0002] With the improvement of people's living standards, the demand for resources is increasing. In human's daily activities, a lot of waste heat has not been effectively recycled and wasted directly. It is a pity, and the existing heat storage devices are generally large in size, complex in structure and not compact enough, and cannot meet the requirements. Portable use requirements are generally used in large-scale industrial production processes, which are not suitable for daily use, and the heat exchange efficiency is not too high, and they all have a limited service life, cannot be recycled, and are difficult to disassemble However, the heat storage device after the end of its service life cannot be recycled, and is generally discarded directly, causin...
