Example Embodiment

[0031] Example 1

[0032] The phase change thermal insulation wall of a prefabricated building of the present invention is realized as follows: The phase change thermal insulation wall of a prefabricated building of the present invention includes an outdoor wall surface (1), a steel wire mesh (2), and a phase change outer layer. (3) The phase change inner layer (4), the main wall (5), the thermal insulation layer (6) and the interior decoration surface (7) are arranged in sequence from the outside to the inside, and the phase change outer layer (3) also It includes a screw cap (8), a perforation (18) and a cover plate (19). The screw cap (8) is placed on one side of the phase change outer layer (3), and the wind cover plate is placed outside the phase change. On the other side of the layer (3), the wind cover is a regular hexagonal plate, the phase change outer layer (3) is provided with a perforation (18), and the perforation (18) penetrates the center of the wind cover, The ph...

Example Embodiment

[0042] Example 2

Abstract

The invention provides a phase change thermal insulating wall body of a fabricated type building and discloses a filling cavity formed by a honeycomb trough which is of dense and even distribution, and a phase change thermal insulating wall body which realizes buffer deformation for volume expansion of phase change materials during phase change to solve the problem of cracks in a phase change layer. The wall body is characterized in that, the wall body comprises an outdoor wall body surface, a steel mesh, a phase change outer layer, a phase change inner layer, a main wall body, a thermal insulating layer and an indoor decorative surface which are arranged in sequence from outside to inside; the wall body can realize buffer deformation for volume expansion of the phase change materials during phase change, so the internal stress of the phase change layers is lowered and occurrence of cracks is avoided; and the honeycomb trough of dense and even distribution is utilized to form a phase change material filling cavity which is densely distributed on a wall surface, and thermal insulating effect of the entire wall surface is guaranteed.

Description

technical field [0001] The invention discloses a phase-change thermal insulation wall of a prefabricated building, which relates to a phase-change thermal insulation wall used in a prefabricated building, and belongs to the field of construction engineering. In particular, it relates to a phase-change thermal insulation wall that buffers and deforms volume expansion during phase-change of phase-change materials through densely and evenly distributed honeycomb groove-shaped filling cavities, so as to solve the problem of phase-change layer cracking in the background technology. Background technique [0002] Phase-change insulation materials refer to substances that change form with temperature changes and can provide latent heat. The process of phase-change materials changing from solid to liquid or from liquid to solid is called a phase change process. At this time, the phase change material will absorb or release A large amount of latent heat, and because phase change mater...
