Three-dimensional pulsating heat pipe phase change material coupling energy storage system

Abstract

The invention discloses a three-dimensional pulsating heat pipe phase change material coupling energy storage system. The structure comprises a plurality of energy storage sub modules, pulsating heat pipes, fins, energy storage boxes, a phase change material, a heat release runner, a heat charging runner and sealing gaskets, wherein the fins are distributed at the upper, middle and lower parts of the pulsating heat pipes; the fins are arranged inside the heat release runner, the energy storage boxes and the heat charging runner; and the energy storage boxes are filled with the phase change material. According to the system, the high thermal conductivity, flexible structure and low cost advantages of the pulsating heat pipes and the high latent heat advantage of the phase change material are reasonably combined together, the structure is simple and compact, the system shape can be flexibly changed according to the actual structure, the plurality of sub modules can be connected to form a large energy storage system, after proper combination and design, the plurality of sub modules are applicable to recycling and utilization of various industrial waste heat, and the system has wide market prospects and environmental protection value.

Description

technical field [0001] The invention belongs to the field of industrial waste heat utilization and thermal energy storage, and in particular relates to a three-dimensional pulsating heat pipe phase change material coupled energy storage system. Background technique [0002] With the development of the global economy and society, energy consumption and environmental pollution have become major problems, and energy conservation and emission reduction have become increasingly urgent. my country's industrial energy consumption accounts for about 70% of the total energy consumption in the country, and the energy consumption is relatively large. Among them, the utilization rate of industrial waste heat is low, and the energy is not fully utilized. The energy consumed is exhausted in various forms of waste heat. Therefore, my country is rich in waste heat resources, and waste heat recovery and utilization can further improve energy utilization efficiency, thereby reducing the use of...
