Description
Technical Field
The utility model belongs to the technical field of solar energy, and particularly relates to an aerogel solar heat collection and storage wall.
Background
Under the great background that the global energy conservation and emission reduction and China policy greatly support the utilization of renewable energy sources, the development of a reasonable renewable energy source utilization mode is imperative. Solar energy is widely distributed and easy to obtain, and is distinguished from renewable energy sources according to the characteristics of local conditions, so that various utilization modes are produced. The passive solar energy building is a building energy-saving technology which does not need external mechanical energy to drive and simply operates by means of self structure and material characteristics, wherein the solar heat collection and storage wall is used as a passive component, the processes of solar energy collection, storage and release can be realized, and the thermal load of the building can be reduced by installing the solar energy collection and storage wall on the outer surface of the building. Therefore, the solar heat collection and storage wall has great development prospect in the field of building energy conservation.
The principle of the solar heat collection and storage wall is that in the daytime in winter, the heat absorption layer positioned on the outer wall of the heavy wall body is heated after receiving solar radiation, the air interlayer between the heat absorption layer and the glass cover plate is further heated, and indoor air enters the air interlayer and is heated to enter the room and then is recycled repeatedly, so that the indoor environment temperature is increased. However, the solar heat collection and storage wall has a problem that a heavy wall body which is an important component of the heat collection and storage wall has two specifications of 240mm thickness and 370mm thickness in north China, if the 240mm specification is favorable for transmitting daytime heat into a room in a heat conduction mode, but when solar radiation is not generated at night, the phenomenon of heat backflow can occur due to the fact that the thermal resistance of the wall body is too thin, if the wall body is of a thick specification of 370mm, the heat backflow can be reduced to a certain extent, but the heat is prevented from entering the room due to too large thermal resistance in daytime, and both the problems are difficult to consider.
Aiming at the problems that the thermal backflow and the heat conduction capability of a solar heat collection and storage wall are limited, two main solutions exist in the prior art, namely, a 240 mm-specification wall body is adopted, a heat insulation material is manually added to an air interlayer at night or when solar radiation is weak, so that heat loss is prevented, the method has the defects of complex operation, and meanwhile, the preservation of the heat insulation material and accidental damage risk are also involved. Another method adopts a wall body with 240mm specification, but changes the width of the air interlayer, thins the air interlayer, inhibits the air flow of the interlayer, and approximately changes the convection heat transfer mode into a heat conduction process, so as to prevent heat loss, but the method limits the diurnal air circulation heating process to a certain extent.

The utility model has the technical effects that: 1. the utility model has simple structure, and the aerogel layer is light in material and has no influence on structural bearing by only adding the aerated gel layer on the inner wall of the glass cover plate. 2. The aerogel layer adopted by the utility model has higher light transmittance and smaller reduction effect on solar radiation, and the aerogel and the air interlayer independently exist, so that the space of the air interlayer is not influenced, the process of heat transfer from the wall body to the indoor is not influenced, and the heat collection and transfer process of the wall body is less influenced. 3. According to the utility model, the aerogel layer is directly used as a part of the wall body when the heat collecting and accumulating wall is constructed, compared with the existing night heat insulating layer, the aerogel layer does not need to be manually operated, and meanwhile, the abrasion of the heat insulating material in the preservation process is reduced.

Detailed Description
Example 1
As shown in fig. 1 and fig. 2, an aerogel solar heat collecting and accumulating wall comprises a glass cover plate 1 and a heavy wall body 6, wherein an aerogel layer 2 is arranged on one side surface of the glass cover plate 1, which is close to the heavy wall body 6, a heat absorbing coating 4 is arranged on one side surface of the heavy wall body 6, which is close to the glass cover plate 1, an air interlayer 3 is arranged between the aerogel layer 2 and the heat absorbing coating 4, an upper heat insulating baffle 5 is arranged on the upper portion of the heavy wall body 6, and a lower heat insulating baffle 7 is arranged on the lower portion of the heavy wall body 6.
The utility model has simple structure, and the aerogel layer 2 is light in material and has no influence on structural bearing by only adding the aerogel layer 2 on the inner wall of the glass cover plate 1. The aerogel layer 2 adopted by the utility model has higher light transmittance and smaller reduction effect on solar radiation, and because the aerogel and the air interlayer 3 exist independently, the space of the air interlayer 3 is not influenced, the process of heat transfer from a wall body to an indoor is not influenced, and the heat collection and transfer process of the wall body is less influenced. According to the utility model, the aerogel layer 2 is adopted, when the heat collection and storage wall is constructed, the aerogel layer 2 is directly used as a part of the wall body, compared with the existing night heat insulation layer, the artificial operation is not needed, and meanwhile, the abrasion of the heat insulation material in the preservation process is reduced.
Example 2
On the basis of embodiment 1, in this embodiment, preferably, the aerogel layer 2 is closely attached to the surface of the glass cover plate 1, and the thickness of the aerogel layer 2 is equal to or greater than 12mm.
According to the utility model, the aerogel layer 2 is tightly attached to the surface of the glass cover plate 1, the thickness of the aerogel layer 2 is more than or equal to 12mm, the aerogel layer 2 is light in material, and the structural bearing aspect is not influenced.
The working principle of the utility model in practical use is as follows: referring to fig. 1, during winter, solar radiation irradiates on a heat absorbing coating 4 through a glass cover plate 1 and aerogel 2, an upper heat insulating baffle 5 and a lower heat insulating baffle 7 are opened, cavity air is heated after the temperature of the heat absorbing coating 4 rises, the heated density of the air is reduced and rises, the air enters a room through an opening at the upper part, and meanwhile, heat is conducted indoors through a heavy wall 6. Referring to fig. 2, the upper and lower heat insulation barriers 5 and 7 are closed at night, the temperatures of the heavy wall 6 and the room are higher than those of the outside, and the heat backflow phenomenon starts to occur, so that the heat loss of the heavy wall 6 and the room to the outside is greatly reduced due to the very small heat conductivity coefficient of the aerogel 2, and the heat loss caused by the heat backflow is slowed down to a certain extent.
The utility model provides an aerogel solar heat collecting wall which does not need manual operation and has small influence on the heat collecting and transferring process of a wall body. The aerogel directly becomes a part of the wall body when constructing the wall body, the aerogel does not need to be repeatedly installed by manpower, and because the aerogel has lower heat conductivity coefficient, the aerogel has better advantages than the existing thermal insulation material added at night, better effect than the existing thermal insulation material can be obtained, and because of the existence of the aerogel layer, the heat backflow is not required to be reduced by constructing a 370mm heavy wall body, only the 240mm wall body is adopted, and meanwhile, the 240mm wall body is more beneficial to the heat transfer from the wall body to the indoor in daytime.
The present utility model is not limited to the above-mentioned embodiments, and any changes or substitutions that can be easily understood by those skilled in the art within the technical scope of the present utility model are intended to be included in the scope of the present utility model.
