Technical Field

The utility model belongs to the technical field of the building materials, a leak protection phase transition energy storage board is related to.

Background

Phase change materials generally store and release heat by changing their physical states in a certain temperature range and absorbing or releasing heat through phase change, and are generally realized through solid-liquid phase change. Since phase change materials absorb or release a large amount of heat in comparison with sensible heat during phase change, they are used to accumulate heat or cold. However, most of the existing insulation boards using phase-change materials can only store one phase-change material with a phase-change temperature, and can only be used in one season.

In order to solve the problems, the chinese patent CN 107167012 a discloses an energy storage plate capable of rapidly replacing a phase change medium, which comprises a shell, a heat insulation layer, an energy storage layer, and a shell cover, wherein the shell is a cuboid box with an opening on one side, and the shell cover corresponds to the opening of the shell; the bottom of casing sets gradually heat preservation, energy storage layer, sets up phase change material in the energy storage layer, and the cap passes through the mode of lock joint to be installed on the opening of casing. Because the dismouting that the cap can be convenient, consequently the phase change material in the removable energy storage layer packs heat accumulation phase change material in the board in winter, changes into cold-storage phase change material in summer.

However, the loading of the phase change material is realized through the phase change material storage bag, the bag structure is prone to crack and leakage, the shell and the shell cover are designed to be laterally opened, and once the phase change material storage bag is cracked, the phase change material is prone to flow out along the seam between the shell and the shell cover, so that the environment is polluted.
