The invention discloses a compact type stepped heat storage and supply system and method based on a closed gravity assisted heat pipe. The compact type stepped heat storage and supply system based onthe closed gravity assisted heat pipe comprises a high-temperature heat storage module, a transition heat storage and exchange module, a transmission heat switch structure, a heat supply output moduleand a heating control system. According to the compact type stepped heat storage and supply system and method based on the closed gravity assisted heat pipe, a high-temperature sensible heat accumulator and a medium-low-temperature phase change heat accumulator are cascaded, so that high energy storage density is provided, continuous and stable output power is guaranteed, and rapid storage and output of heat can be realized by utilizing high heat conductivity of the high-temperature sensible heat accumulator. According to the compact type stepped heat storage and supply system and method based on the closed gravity assisted heat pipe, by using the closed gravity assisted heat pipe with extremely high heat exchange coefficient to carry out interstage heat transportation, the interstage heat transfer efficiency is enhanced, energy dissipation in the heat transferring process is reduced, the compactness of the system structure is enhanced, and moreover, the interstage heat transfer poweris adjusted by changing the position of the heat pipe. Through the implementation of the compact type stepped heat storage and supply system and method based on the closed gravity assisted heat pipe,the applicability and reliability of the heat storage and supply system in engineering application can be enhanced.
Description
technical field [0001] The invention relates to a compact cascade heat storage heat supply system and method based on closed gravity heat pipes, and belongs to the intersection field of sensible heat heat storage heat supply technology and phase change heat storage heat supply technology. Background technique [0002] The production and demand of energy are different in time and space, so the effective use of energy is inseparable from efficient energy storage. In recent years, energy storage technology has developed rapidly with the support of the government and the market, and the concept of energy storage peak shaving has become more and more popular. As an important way of energy storage, heat storage also has broad development prospects. [0003] At present, there are three main heat storage technologies: sensible heat storage, phase change heat storage and chemical heat storage. Sensible heat storage technology uses material temperature changes to store heat, which i...
