Abstract

The invention discloses a flexible lightweight shape-stabilized phase change energy storage piece and a preparation method thereof, and relates to the technical field of materials, in particular to aphase change energy storage piece. The flexible lightweight shape-stabilized phase change energy storage piece comprises the following components in parts by weight: 1 to 10 parts of array shape-stabilized bodies, 10 to 90 parts of heat conducting phase change energy storage materials, 2 to 50 parts of heat conducting gap filling materials, and 3 to 30 parts of fixing glue. The flexible lightweight shape-stabilized phase change energy storage piece has the advantages that a flexible micro sealing bag is manufactured into an array shape-stabilized body, and an array unit structure is formed toplay a role of stabilizing the shape of the heat conducting phase change energy storage materials and shorten the melt flowing distance during solid-liquid conversion of the phase change energy storage materials, so that the influence on the shape of the phase change energy storage piece by gravity is reduced on the premise that the flexibility of the phase change energy storage piece is kept, andmeanwhile, a casing material adopts resin or aluminum foils, so that the overall mass of the change energy storage piece is lighter.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to a phase-change energy storage sheet. Background technique [0002] A phase change material is a material that absorbs or releases a large amount of latent heat of phase change through a solid-liquid phase change while maintaining a constant temperature or a small change in temperature. The common solid-liquid phase change material will flow due to melting during the phase change, so the phase change material needs to be packaged to make a phase change energy storage sheet during application, but the existing phase change energy storage sheet has a shell density Large, non-flexible, phase-change energy storage sheets are susceptible to problems such as uneven distribution due to gravity. Contents of the invention [0003] The purpose of the present invention is to provide a flexible and lightweight shaped phase-change energy storage sheet to solve at least one of the above te...
