Production technology for shaped phase-change energy storage module

Abstract

The invention relates to the technical field of phase-change energy storage modules, in particular to a production technology for a shaped phase-change energy storage module. The production technology comprises the following steps: S1, pretreating: preparing a reaction part of an organic phase-change material, mixing the reaction part at the temperature of 80 to 100 DEG C for 20 to 30 minutes; S2, blending and processing: continuously blending 75 to 85 percent of organic phase-change material reaction part, 10 to 20 percent of matrix material reaction part and 2 to 5 percent of heat conduction reinforcing agent at the temperature of 80 to 100 DEG C for 10 minutes and then carrying out high-speed mixing by a double screw at the high temperature of 120 to 160 DEG C to form a high temperature mixed material; S3, pouring: pouring the mixed material obtained in the S2 in a mold with a fiberglass mesh; S4, forming: carrying out thermal curing for 2 to 5 hours, cooling to room temperature and then carrying out demoulding. The phase-change energy storage module has the advantages of simple production technology, good heat conduction performance, stable shape, low requirements on packaging containers, environment friendliness in raw materials and wide application field.

Description

technical field [0001] The invention relates to the technical field of phase change energy storage modules, in particular to a production process of a shaped phase change energy storage module. Background technique [0002] Phase change energy storage is to absorb the heat or cold of the external environment during the phase change process, and release the heat or cold to the environment when needed, so as to achieve the purpose of controlling the surrounding environment. [0003] The most commonly used phase change material at home and abroad is a solid-liquid phase change type, which is easy to leak, corrode, and pollute the environment, so it must be used in a sealed container. Materials with solid-solid phase transition properties can overcome the above-mentioned shortcomings. The shape-stable phase change material is a composite material composed of a working substance and a carrier matrix. When the working substance undergoes a phase change, its shape remains solid. ...
