Description

[0004] The second type is a permeable air collector, which is composed of a porous heat absorbing plate, a surrounding structure and a back plate, the air outside directly enters the inside of the collector from the small holes on the heat absorbing plate, and then is heated in the cavity of the collector, due to the removal of the glass cover plate, its structure is simpler, lighter and more durable, and is easier to maintain in the later period, although the permeable air collector has certain heat preservation measures, but due to the good thermal conductivity of metal, in the environment with crosswind, the air and the porous heat absorbing plate directly exchange heat, which causes the heat of the collector to be easily lost to the outside, resulting in large heat loss.

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0025] In order to make the above-mentioned purposes, features and advantages of the utility model more apparent, obvious and easy to understand, the utility model will be further described in detail below with reference to the drawings and specific embodiments.

[0026] Referring to Figs. 1 to 4 The embodiment provides a honeycomb mesh type permeable solar air collector, which comprises:

[0027] An air flow channel 2 is open at the top surface;

[0028] A honeycomb mesh 1 is fixedly installed at the top of the air flow channel 2, and the honeycomb mesh 1 comprises a plurality of array holes in communication with each other, which are in communication with ambient air and the inner cavity of the air flow channel 2;

[0029] A fan 3 is fixedly installed on one side of the air flow channel 2 and used for driving air in the air flow channel 2 to be discharged.

[0030] Compared with a cover plate type solar air collector, the glass cover plate is removed, energy loss caused by reflection and shielding of the glass cover plate is avoided, obstruction of the temperature gradient formed by the cover plate to the flow of hot air is eliminated, ambient air can be directly contacted with the honeycomb mesh 1 and the air flow channel 2, and the heat exchange coefficient is improved. Meanwhile, the honeycomb mesh 1 is in the form of a pipe bundle with a plurality of array holes as a whole, so that when sunlight is irradiated, the light beam is divided into two parts, the first part is irradiated to the inner wall of the array hole of the honeycomb mesh 1, and the second part is directly irradiated to the air flow channel 2. The light beam irradiated into the collector can avoid the convective heat exchange with the ambient crosswind, and a part of heat loss is reduced. The second part of the light beam is continuously reflected and absorbed in the honeycomb mesh 1 structure, so that the structure of the honeycomb mesh 1 increases the heat collection area on the one hand and realizes the natural concentration and guiding effect of heat on the other hand, maximizes the absorption and retention of heat energy from the sun, and improves the heat absorption efficiency.

[0031] The embodiment provides a honeycomb mesh type permeable solar air collector, and one side of the air flow channel 2 is in communication with a connecting flow channel 5 close to the fan 3. The connecting flow channel 5 gradually decreases outward along the air flow channel 2, the smaller end of the connecting flow channel 5 is in communication with an air outlet pipe 4, and the fan 3 is fixedly connected in the air outlet pipe 4.

[0032] During the process that air flows from the honeycomb mesh 1 to the air outlet pipe 4 through the air flow channel 2, the cross-sectional area of the connecting flow channel 5 gradually decreases, according to the principle of fluid mechanics, the air flow speed is accelerated, which is helpful to more efficiently transport the heated air to the air outlet pipe 4, so that the hot air can provide heat to buildings or drying boxes more quickly. In terms of optimizing pressure distribution, the connecting flow channel 5 can adjust the pressure change of the air flow in the collector, so that the whole air flow process is more smooth and stable, the air flow connection between various components is more reasonable, energy loss and air flow turbulence are reduced, and thus the overall performance and working efficiency of the collector are improved.

[0033] This embodiment provides a honeycomb mesh type permeable solar air collector. The honeycomb mesh 1 includes several upper inserts 6 and lower inserts 7. Several openings are evenly provided at the bottom of the upper inserts 6 and several openings are provided at the top of the lower inserts 7. The upper inserts 6 and lower inserts 7 are vertically arranged and are connected by interlocking the openings to form an array of holes.

[0034] The honeycomb mesh 1, formed by the interlocking of the upper insert 6 and the lower insert 7, is in the form of a hole array, and the aperture of the array holes can be adjusted according to different environmental conditions. This flexibility allows the solar collector to adapt to diverse usage scenarios and climatic conditions. Under different environmental factors such as light intensity, temperature, humidity, and air quality, by adjusting the aperture to optimize airflow and heat absorption efficiency, the versatility and adaptability of the solar collector are enhanced, ensuring good working performance in various environments.

[0035] This embodiment provides a honeycomb mesh type permeable solar air collector, wherein the surface of the honeycomb mesh 1 is coated with black paint.

[0036] Black has a high absorption rate, enabling it to better absorb solar radiation. When sunlight shines on the honeycomb mesh 1 coated with black paint, the paint allows the structural surface to absorb as much solar heat as possible and transfer it to the flowing air, thereby improving the heat collection efficiency of the collector. This allows the collector to more effectively convert solar energy into heat energy, meeting the heat demands of building heating and drying.

[0037] This embodiment provides a honeycomb mesh infiltration type solar air collector, in which a boss 8 is fixedly attached to the inner wall of the air channel 2, and the honeycomb mesh 1 abuts against the boss 8.

[0038] The boss 8 provides a stable fixed support point for the metal honeycomb mesh structure 1, ensuring that the metal honeycomb mesh structure 1 is accurately and stably positioned in the solar collector.

[0039] This embodiment provides a honeycomb mesh infiltration type solar air collector, where the airflow channel 2 is a rectangle of 600mm × 600mm.

[0040] The selection of a 600mm × 600mm rectangular dimension as the main body size of the airflow channel 2, i.e., the solar collector, is of great importance. Firstly, this size is consistent with commonly used ceramic tiles, allowing for a closer fit to the building's exterior wall in architectural applications. After installation, the solar collector integrates better with the building's appearance, enhancing overall aesthetics and meeting architectural requirements. Secondly, this standardized size design facilitates manufacturing and installation. In the production process, existing production processes and equipment can be utilized, improving production efficiency and reducing costs. During installation, it is also easier to adapt to the building's structure and layout, reducing installation difficulty and workload, which is conducive to the large-scale promotion and application of the solar collector.

[0041] Workflow:

[0042] When this application is in operation, it is placed vertically with the air outlet 4 facing upwards. Under solar radiation, the upper honeycomb mesh 1 heats the air. The heated ambient air is guided by the rotation of the fan 3 and flows in through the honeycomb mesh 1, through the air flow channel 2 and the connecting flow channel 5 into the air outlet. The heated air then provides hot air to buildings or drying boxes.
