Abstract

The invention relates to a solar instantaneous water-based phase change heat accumulator which comprises a double-layer vacuum glass jacketing, a mixture of energy storage particles and water, a heat exchange copper calandria and an anti-expansion spring plug, wherein the double-layer vacuum glass jacketing is cylindrical; an outlet and an inlet of the heat exchange copper calandria are positioned outside the double-layer vacuum glass jacketing, and are symmetrically formed in the outlet end of the double-layer vacuum glass jacketing up and down; other parts of the heat exchange copper calandria are wound inside the double-layer vacuum glass jacketing; the space between the heat exchange copper calandria in the double-layer vacuum glass jacketing and the inner wall of the double-layer vacuum glass jacketing is filled with the mixture of energy storage particles and water; and the center of the outlet of the double-layer vacuum glass jacketing is sealed with the anti-expansion spring plug. According to the solar instantaneous water-based phase change heat accumulator, the solar absorptivity can be effectively improved, the heat loss due to radiation is reduced, and a wider approach for the application of solar thermal collectors is developed.

Description

technical field [0001] The invention relates to an energy storage device, in particular to a solar energy instantaneous water-based phase change heat accumulator. Background technique [0002] As an unlimited renewable energy source, solar energy has become more and more popular in recent years. However, due to factors such as geography, weather, and seasons, the use of solar energy has been interrupted. In order to enable continuous use of solar energy, energy storage must be effectively solved. question. [0003] The currently used solar heat accumulators generally have low efficiency and slow heat exchange. Most of the solar energy is reflected back into the atmosphere without being absorbed by the heat accumulator. From the perspective of energy utilization, its efficiency is very low and it is inconvenient to use. Contents of the invention [0004] The invention aims at the problem of low utilization efficiency of solar heat storage energy, and proposes a solar ener...
