[0002] With increasing global energy demand and heightened environmental awareness, building energy conservation has become a research hotspot. Furthermore, energy conservation and carbon reduction are becoming key priorities for future building development, placing higher demands on building materials. While traditional building wall insulation materials can reduce heat transfer to a certain extent, they often suffer from limited insulation effectiveness, aging, and complex construction. Phase change energy storage materials, due to their ability to absorb or release large amounts of latent heat within a specific temperature range, exhibit significant potential for regulating indoor temperatures, improving living comfort, and reducing building energy consumption.

[0003] However, the current application of phase change energy storage materials in buildings is relatively complicated. The installation of this material will increase on-site construction work, make the site unsightly and inconvenient. How to ensure the functional effects of phase change materials while solving the packaging, leakage prevention, thermal stability and durability of phase change materials to make them efficient and practical, and effectively integrate phase change energy storage materials into building structures, especially partition walls and external protective structures, is still a technical difficulty in the field of building energy conservation.

Multiple phase change energy storage modules 2 are vertically spaced within the wall panel outer frame keel 1, and the outer surfaces of the phase change energy storage modules 2 are flush with the outer surfaces of the wall panel outer frame keel 1. A set of U-shaped support keels 3 arranged horizontally are evenly spaced at the installation position of each phase change energy storage module 2 within the wall panel outer frame keel 1. The two ends of the U-shaped support keel 3 are respectively fixedly connected to the inner wall of the vertical keel 11. The phase change energy storage module 2 is fixed to the set of U-shaped support keels 3.

[0021] Furthermore, the system includes multiple reinforcing keels 5 arranged horizontally, one between the mounting locations of two adjacent phase-change energy storage modules 2. The ends of these reinforcing keels 5 are fixedly connected to the outer walls of the vertical keels 11. Wall aggregate 4 is arranged within the space within the wallboard outer frame keel 1, excluding the mounting locations of the phase-change energy storage modules 2. The outer surface of the wall aggregate 4 is flush with the outer surface of the phase-change energy storage modules 2.

[0022] In this embodiment, the phase-change energy storage module 2 is rectangular and is a phase-change thermostatic blanket. The blanket uses aluminum foil and fiber cloth technology to encapsulate the phase-change energy storage material. Multiple horizontal and vertical fixing portions, not filled with phase-change material, are provided in the middle of the phase-change energy storage module. These fixing portions are used to securely connect to the U-shaped support keel with self-tapping screws. It should be noted that the phase-change thermostatic blanket in this embodiment is a pre-existing product, model GXP CM-S24 / GXP CM-S25.

[0023] In this embodiment, a phase change energy storage module 2 is provided on the front side of the wall panel outer frame keel 1. In other embodiments, phase change energy storage modules 2 can be provided on both the front and rear sides of the wall panel outer frame keel 1, that is, the phase change energy storage module 2 is provided on a single side or double sides in the phase change energy storage integrated unit partition board, which can be selected according to actual construction.

[0024] In this embodiment, each group of U-shaped support ribs 3 contains three, with the spacing between two adjacent U-shaped support ribs 3 being 200 mm. The three U-shaped support ribs 3 are positioned at the top edge, bottom edge, and center of the phase-change energy storage module 2. The phase-change energy storage module 2 has an area of 600 × 420 mm and a latent heat value of 290 kJ / kg. The vertical ribs 11 are cold-bent, thin-walled, U-shaped galvanized steel to ensure the overall strength and stability of the partition board. The openings of the left and right vertical ribs 11 are positioned opposite each other, and each group of transverse ribs 12 consists of two symmetrically arranged L-shaped angle steels, each of which is fixedly connected to the front and rear outer walls of the vertical ribs 11.

[0025] In this embodiment, the wall aggregate 4 utilizes a conventional magnesium-based composite slurry, which exhibits excellent thermal insulation, water resistance, and compressive strength. The solidified board is lightweight and easy to install. During the pouring process, the filling slurry encapsulates and secures the phase change energy storage module.

[0026] Example 2:

[0027] The preparation method of the utility model is introduced below:

[0028] Step 1: According to the design requirements, pre-process and assemble the wall panel outer frame keel 1 to form the main structural frame of the partition board, and then install the U-shaped support keel 3 for fixing the phase change energy storage module 2. The distance between two adjacent U-shaped support keels 3 in each group is 200 mm.

[0029] Step 2: Fix multiple phase change energy storage modules 2 on multiple groups of U-shaped support keels 3 in sequence according to predetermined positions, and fix them in corresponding positions with self-tapping screws to keep the outer surface of the phase change energy storage module flush with the outer surface of the wall panel outer frame keel 1.
