Description

Technical Field

[0001] The present invention relates to the field of solar energy collection technology, in particular to a solar focusing thermal energy module array collection and storage system and a method thereof. Background Art

[0002] Solar thermal technology, which converts solar energy into heat through various means, has been around for a long time and is still evolving. This technology mainly includes passive and active solar systems.

[0003] Passive solar systems rely mainly on the design of buildings to directly absorb, store and distribute solar energy without the assistance of mechanical or electronic equipment. For example, direct benefit solar heating systems allow sunlight to penetrate directly into the room through south-facing windows, making indoor components such as walls and floors act as heat absorbers and heat storage bodies to achieve the effect of heating. This design is simple and low-cost, but its efficiency is limited by the characteristics of the building itself. Passive solar systems rely on the design of the building itself to absorb and store solar energy, which means that it must cover a large area to collect enough energy. For example, in order to meet the heating needs of a family in winter, large windows or other types of heat collection surfaces may be required. This is because the energy density of solar energy is low and it cannot provide a large amount of energy in a small space like fossil fuels. Therefore, when designing passive solar buildings, architects often need to consider how to maximize the use of the building's outer surface to capture solar energy, while also considering insulation measures to reduce heat loss. Summary of the invention

[0004] Therefore, in order to solve the above problems, the purpose of the present invention is to provide a solar focusing thermal energy module group storage system, including a box body, on which a heat storage group and a heat conduction group are provided, the heat storage group includes a plurality of focus-absorbing and heat-conducting belts arranged at equal intervals, the focus-absorbing and heat-conducting belts are composed of a plurality of lens groups, the lens group includes a plurality of convex lenses stacked in sequence, the lens group is arranged toward the heat conduction group, the heat conduction group includes a heat pipe, one end of the heat pipe extends out of the box body.

[0005] Preferably, the heat conduction group further includes a heat transfer tube, the lens group is arranged toward the heat transfer tube, and the box is filled with a heat storage medium.

[0006] Preferably, a plurality of the boxes are arranged in a matrix and assembled into a heat collection array, and the heat pipes in the plurality of boxes are interconnected to form a delivery end on one side of the heat collection array.

[0007] Preferably, the heat conducting pipe is loaded with a heat conducting fluid.

[0008] Preferably, a semicircular cover is provided on the box body, and the heat storage group is arranged on the semicircular cover.

[0009] Preferably, the heat storage group includes 5 focus-absorbing and heat-conducting belts.

[0010] Preferably, 12 boxes are included.

[0011] A method for utilizing solar thermal energy. The solar focusing thermal energy module array storage system is arranged in a place with sunlight, and one end of the heat pipe is connected to a device requiring thermal energy.

[0012] The beneficial effects of the present invention are:

[0013] (1) By using a lens group consisting of multiple stacked convex lenses in each focusing heat conducting belt, the efficiency of solar light collection can be significantly improved. This multi-layer lens design not only shortens the distance of solar energy focusing, but also increases the energy density at the focus, so that the heat conducting pipe per unit area can receive more heat energy;

[0014] (2) The curved surface structure of the semicircular cover provides an ideal installation platform for the focusing and heat-conducting belt, allowing each lens group to face different directions, ensuring that no matter where the sun is in the sky, there is a corresponding lens group that can directly aim at the sunlight. This design eliminates the limitation that traditional flat collectors can only work effectively within a specific period of time, and achieves efficient energy collection over a longer period of time.

[0027] Embodiment 1:

[0028] Figure 1-6 The solar focusing thermal energy module group storage system provided by the present invention is shown, including a box 1, the box 1 is provided with a heat storage group and a heat conduction group, the box 1 is used to load the heat storage group and the heat conduction group, the heat storage group includes a plurality of focus absorbing heat conduction belts arranged at equal intervals, the focus absorbing heat conduction belts are composed of a plurality of lens groups 2, a plurality of lens groups 2 are arranged one by one along a straight line, the lens group 2 includes a plurality of convex lenses 21 stacked in sequence, the lens group 2 is arranged toward the heat conduction group, and the concentrated solar heat energy is accurately conducted to the heat conduction group, and the convex lenses 21 stacked in sequence enable the lens group 2 to achieve a high concentration of sunlight within a relatively short distance. This design not only shortens the distance from the light entering the system to being absorbed by the heat conduction group, but also increases the energy density per unit area.

[0029] The heat conduction group includes a heat conduction pipe 3 and a heat transfer pipe 31. One end of the heat conduction pipe 3 extends out of the outer side of the box body 1 and can be connected to an external device to transport heat energy. The heat transfer pipe 31 is arranged below the lens group 2, and the lens group 2 is arranged toward the heat transfer pipe 31. The box body 1 is filled with a heat storage medium 6. The solar thermal energy is concentrated in the heat transfer pipe 31 and then transferred to the heat storage medium 6, and then transported to the heat conduction pipe 3. The heat storage medium 6 can be asphalt or low-temperature wax.

[0030] A number of boxes 1 are arranged in a matrix and assembled into a heat collection array, which includes a plurality of heat pipes 3. The heat pipes 3 in different boxes 1 are interconnected to form a grid of heat pipes 3. The heat pipes 3 form a delivery end on one side of the heat collection array, which can be connected to various types of equipment or scenes requiring thermal energy, such as water pipes for thawing in winter and planting sheds. Thermoelectric power generation sheets 7 can also be attached to the surface of the box. There is a temperature difference between the surface of the box and the outside world. Thermoelectric power generation sheets 7 are mature products. The voltage and current of the front and back sides are different due to the temperature and area size. Usually, the voltage of each sheet is 1-2V and the current is about 400mA. Thermoelectric power generation sheets 7 can provide a certain degree of power supply. In this embodiment, 12 boxes 1 are configured and arranged in the form of 3 horizontal rows and 4 vertical rows.

[0031] The heat pipe 3 is loaded with a heat transfer fluid, which may be a commonly used heat storage medium 6 such as water or ethylene glycol.

[0032] The box body 1 is covered with 6 groups of semicircular covers 5, and the focus-absorbing and heat-conducting belts are evenly laid on the semicircular covers 5. In this embodiment, 5 groups of focus-absorbing and heat-conducting belts are arranged on the semicircular covers, and the lens groups 2 in the focus-absorbing and heat-conducting belts are all arranged toward the heat-conducting groups, and the angles of the two convex lenses 21 are precisely adjusted to ensure that all the concentrated sunlight can be accurately irradiated on the heat-conducting tubes 3, so that the solar thermal energy is accurately concentrated in the heat-conducting tubes 3.

[0033] The lens group 2 has two lenses, and one lens can be removed as needed. The angle of the lens group 2 is pre-adjusted to align with the heat transfer tube 31 .

[0034] Working principle:

[0035] The system uses a lens group 2 composed of multiple layers of convex lenses 21 to achieve high concentration of sunlight within a short distance. This design not only shortens the distance from the light entering the system to being absorbed by the heat transfer group, but also increases the energy density per unit area. By accurately adjusting the angle of each lens group 2, all the concentrated sunlight can be accurately irradiated on the heat transfer tube 31, thereby ensuring efficient energy transfer, and the heat of the heat transfer tube 31 will gradually diffuse into the heat storage medium 6.

[0036] The heat pipe 3 is loaded with a highly efficient heat-conducting fluid, such as water or ethylene glycol, which rapidly absorbs and conducts the high-density heat energy gathered by the heat storage medium 6 through its excellent heat conduction performance. This not only improves the energy conversion efficiency of the system, but also ensures stable operation even in a low-temperature environment.

[0037] Multiple boxes 1 are arranged in a matrix and assembled into a heat collection array, and the heat pipes 3 in different boxes 1 are connected to each other to form a grid of heat pipes 3, thereby simplifying the centralized heat transmission process and improving the redundancy and stability of the entire system. In this way, the system can flexibly respond to different energy needs and is easy to expand and maintain.

[0038] The design of the semi-circular cover 5 provides an ideal mounting platform for the focusing belt, so that each lens group 2 can face different directions, so that the sun can be effectively captured no matter where it is in the sky. This all-round energy capture mechanism, combined with effective thermal insulation measures, further reduces unnecessary heat loss, thereby enhancing the overall efficiency of the system.

[0039] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
