Abstract

The invention provides a vacuum heat insulation type heat / cold storage device which comprises a shell, wherein the shell is filled with an energy storage medium, the shell comprises a shell inner wall, a vacuum layer, a heat preservation layer and a shell outer wall, and the shell inner wall, the vacuum layer, the heat preservation layer and the shell outer wall are sequentially arranged from inside to outside. According to the vacuum heat insulation type heat / cold storage device provided in the invention, the temperature field stability of the heat / cold storage device in the alternating process of energy storage and energy release can be improved, and the energy storage characteristic of the heat / cold storage device is effectively improved.

Description

technical field [0001] The invention relates to the technical field of energy storage equipment, in particular to a vacuum insulation heat storage / cooler. Background technique [0002] At present, as the core component of heat storage and cold storage technology, the heat storage / cooler adopts a packed bed structure for heat storage or cold storage, which has the advantages of environmental protection, safety, stability, and low cost, and is easy to realize large-scale application. However, the energy storage efficiency and heat transfer performance of the heat storage / cooler in the form of a packed bed directly depend on the internal temperature field and flow field distribution of the heat storage / cooler. Therefore, the optimization of the temperature field and flow field of the heat storage / cooler is particularly important. important. [0003] During the energy storage and energy release process of the heat storage / cooler with the existing packed bed structure, the heat ...
