TECHNICAL FIELD
The present invention relates to the technical field of building materials,
and particularly relates to a phase-change energy storage solar panel and a
preparation method therefor.
BACKGROUND
The solar panel is a new building material mainly integrating lighting and
sound insulation, and featured by light weight, high strength, durability and
easy processing. However, due to heat preservation and poor energy-saving
performance, it is able to greatly affect indoor temperature, as reflected in the
greenhouse building with solar panels. The indoor temperature can reach
about 40 0C in summer, which is about 8 0C higher than the outdoor
temperature due to the greenhouse effect; in contrast, when the outdoor
temperature is -20 °C in winter nights, the indoor temperature can reach -12
°C and the temperature and heat cannot be maintained.
SUMMARY
The purpose of the present invention is to provide a phase-change
energy storage solar panel and a preparation method therefor, aiming at
solving the disadvantages of poor temperature and heat retention and poor
energy-saving effect of solar panels existing in the prior art.
In order to achieve the above purpose, the technical solutions used in the
present invention are as follows: a phase-change energy storage solar panel comprising a collecting plate, an energy storage unit and a frame, wherein the energy storage unit is arranged on one side of the frame and structured as a honeycomb, with each honeycomb being internally filled with or composed of phase-change energy storage materials, and the collecting plate is arranged on one side of the energy storage unit far away from the frame.
A preparation method of a phase-change energy storage solar panel,
characterized by comprising the steps of:
S1. making a frame from polyethylene terephthalate (PET) or polymethyl
methacrylate (PMMA);
S2. manufacturing an energy storage unit structure as multi-layer
honeycombs, with each honeycomb being internally filled with or composed of
phase-change energy storage materials; and
S3. gluing a collecting plate on one side of the energy storage unit.
Preferably, the phase-change energy storage materials are 29T series
phase-change energy storage materials of colorless and transparent
polyethylene glycol.
Preferably, a gap serving as a flow channel for heated air is arranged
between the energy storage units.
Preferably, the energy storage unit is molded at an interval of 0.5 m in the
preparation process in step S2.
Preferably, the frame has a hollow structure and is internally provided
with a thermal insulation material.
Preferably, the thermal insulation material is made of rubber-plastic
sponge.
The beneficial effects of the invention are as follows:
The phase-change energy storage solar panel of the present invention
can absorb heat energy through phase-change energy storage materials at
high temperature to reduce heat transfer to the room in the daytime and
accumulate heat energy. When the temperature drops at night, the heat
energy accumulated by phase-change energy storage materials inside the
solar panel is released to the room, delaying the decline of indoor temperature.
In a word, the phase-change energy storage solar panel plays a role in
regulating and balancing the indoor temperature through the process of
energy storage and energy release of phase-change energy storage materials,
thereby reducing the cooling and heating input, and achieving the purpose of
energy saving.

DESCRIPTION OF THE INVENTION
The technical solution in the embodiments of the present invention will be
described clearly and completely with reference to the figures in the
embodiments of the present invention; obviously, the described embodiments
are only part of the embodiments of the present invention and not all of them.
By referring to Fig. 1, a phase-change energy storage solar panel and a
preparation method therefor are provided. The phase-change energy storage
solar panel comprises a collecting plate 1, an energy storage unit 2 and a
frame 3; wherein the energy storage unit 2 is arranged on one side of the
frame 3 and structured as a honeycomb, with each honeycomb being
internally filled with or composed of phase-change energy storage materials;
featured by high strength, light weight, good sound insulation and heat
insulation, the honeycomb structure not only reduces the heat transfer to the
room at the daytime, but also accumulates heat energy; and the collecting
plate 1 is arranged on one side of the energy storage unit 2 far away from the
frame 3.
The preparation method of a phase-change energy storage solar panel
comprises the steps of:
S1. making a frame 3 from polyethylene terephthalate (PET) or
polymethyl methacrylate (PMMA), which is the main way to make a solar
panel in the prior art;
S2. manufacturing an energy storage unit 2 structured as multi-layer
honeycombs, with each honeycomb being internally filled with or composed of
phase-change energy storage materials; and
S3. gluing a collecting plate 1 on one side of the energy storage unit 2.
Further, the phase-change energy storage materials are 29T series
phase-change energy storage materials of colorless and transparent
polyethylene glycol.
Further, a gap serving as a flow channel for heated air is arranged
between the energy storage units 2.
Further, the energy storage unit 2 is molded at an interval of 0.5 m in the
preparation process in step S2.
Further, the frame 3 has a hollow structure and is internally provided with
a thermal insulation material.
Further, the thermal insulation material is made of rubber-plastic sponge.
In this embodiment, a thermal insulation and energy-saving solar panel is
developed on the basis of the existing solar panel, which absorbs heat energy
through the phase-change energy storage material in the honeycomb energy
storage unit at high temperature. Featured by high strength, light weight, good
sound insulation and heat insulation, the honeycomb structure reduces the
heat conduction to the room at the daytime, and accumulates heat energy.
When the temperature drops at night, the heat energy accumulated by phase
change energy storage materials inside the solar panel is released to the
room, delaying the decline of indoor temperature. The phase-change energy storage solar panel plays a role in regulating and balancing the indoor temperature through the process of energy storage and energy release of phase-change energy storage materials, thereby reducing the input of cooling and heating, and achieving the purpose of energy saving.
The foregoing is only a preferred embodiment of the present invention,
but the protection scope of the present invention is not limited thereto. Various
equivalent substitutions or modifications made by those skilled in the art within
the technical scope disclosed by the present invention according to the
technical solution and inventive concept of the present invention should be
included within the protection scope of the present invention.
