Embodiment Construction

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] like figure 1 An enhanced heat transfer phase change energy storage ball as shown includes a shell 1 made of one or more mixtures of PE, PC, graphite, nano metal powder, and polytetrafluoroethylene, and a hollow space is formed in the shell 1. There is a phase change energy storage filler 2 in the cavity, and an air space 4 is reserved. The average density of the phase change energy storage ball can be controlled by controlling the filling amount of the phase change energy storage filler, so as to achieve its The density of the working fluid in the hot pool is close, so that it can be freely suspended in the working fluid of the hot pool. The materials used in the phase change energy storage filler 2 are low-medium-high temperature phase change materials, including nano-metals and graphite.

[0024] The shell 1 is provided with a heat tr...

Abstract

The invention provides an enhanced heat transfer phase change energy storage ball and a using method thereof.The energy storage ball comprises a shell, a cavity is formed in the shell, phase change energy storage filler is arranged in the cavity, an air space is further reserved in the cavity, a heat transfer rod is arranged on the shell, the heat transfer rod and the shell are integrally formed, and the heat transfer rod is arranged in the cavity. And one end of the heat transfer rod is inserted into the phase change energy storage filler, and the other end of the heat transfer rod protrudes out of the shell.

Description

technical field [0001] The invention relates to the technical field of thermal energy storage, in particular to an enhanced heat transfer phase change energy storage ball and a method for using the same. Background technique [0002] Heating in winter is a problem that must be solved in people's lives. Heating mainly includes steam heat, water heat and electric heat. At present, a thermal storage heating system has appeared in the market, which is used for daytime heating by storing energy during the trough period of electric load at night. In this way, peak shaving and valley filling of the power grid can be realized, the utilization rate of power generation equipment can be improved, and heating electricity costs can be saved at the same time. The heat storage equipment adopts a hot water storage tank and a phase change heat storage ball with a phase change heat storage module. However, the commercialized phase change heat storage balls on the market have a smooth surfac...
