Benefits of technology

This technology improves how well an indoor space's window shades absorb solar light for energy production purposes while also allowing it to efficiently circulate warm or cooled gases through its windows without causing damage from too much exposure during winter months when no outside temperatures warmer than usual. It achieves this by utilizing special materials called heat sinks that have excellent resistance against corrosion caused by external factors like rainwater. Additionally, there may exist other means such as fans to help distribute evenly distributed heat throughout the system. Overall, these improvements improve overall performance and durability of the indoor environment.

Problems solved by technology

This patented describes various challenges related to efficient converting light energy for generating electricity without burning expensive materials such as fossil fuels. Current methods involve collecting large amounts of light beforehand, but they are limited when dealing with complex structures containing multiple components. Therefore, an improved method needs to address these issues while also improving their durability and performance.

Embodiment 1

[0047] A volumetric heat exchanger absorber for solar thermal power generation systems, such as figure 1 As shown, it includes the shell of the heat absorber composed of the straight section 4 of the shell and the cone section 7 of the shell. The rear end of the cone section 7 of the shell is tightly connected with the exhaust pipe 14. The air pipe 13 is provided with a front end cover 3 at the front end, and a cavity is jointly formed by the front end plate 3 , the shell straight section 4 , and the shell cone section 7 , and the shell cone section 7 is connected with the exhaust pipe 14 .

[0048] A lighting port 2 is opened in the middle of the front end plate 3 , and the daylighting port 2 is covered by a glass cover plate 9 , and the pressure ring 10 fastened to the inside of the front end plate 3 is pressed against the glass cover plate 9 .

[0049] Such as figure 1 and figure 2 As shown, the inner side of the straight section 4 of the housing is provided with a porou...

Embodiment 2

[0052] Such as Figure 6 and Figure 7 As shown, the difference from Embodiment 1 is that at least one cooling air duct 24 is provided on the outside of the front end plate 3, and the external cooling air flow 25 flowing in the cooling air duct 24 can be introduced from the upstream cold air inlet. 13 or the cold air 12 of annular flow passage 18, also can be that extra air pump provides cold air. The outlet of the cooling air duct 24 is provided with a nozzle 27 , and the outlet of the nozzle 27 is located at the edge of the lighting opening 2 . One of the outlet shapes of the nozzle 27 is as Figure 8 As shown, it is designed in a flat shape, with several guide vanes 26 built in, so that the cooling air flow ejected from it is close to the outer wall surface of the glass cover plate 9 and at the same time satisfies the designed flow field distribution characteristics. The role of this part of the cooling air flow is: on the one hand, it plays a role in cooling the glass c...

Embodiment 3

[0054] Such as Figure 9 and Figure 10 As shown, the differences between this embodiment and Embodiment 1 are: 1. The porous wall 17 is canceled, and a cold air jacket 28 is arranged on the front side of the front end plate 3, and the cold air jacket 28 and the front end plate 3 form an annular space 31 , the annular space surrounded by the cold air jacket 28 and the front end plate 3 replaces the annular flow channel 18, the air inlet pipe 13 is connected to the cold air jacket 28, and at least one row of air inlet holes 29 is opened on the front end plate 3, The heat collecting cavity 15 communicates with the annular space 31 through the air inlet 29; 2. On the front end plate 3, several guide tubes 30 passing through the front end plate 3 are arranged, and the outlet of the guide tube 30 is also located on the glass cover plate Near the inner wall of 9, one or several holes can be opened on the side of the guide tube 30 facing the glass cover plate 9, so as to organize th...

Abstract

The invention discloses a volume heat exchange heat absorber for a solar heat generation system. The volume heat exchange heat absorber comprises a shell and a heat absorption body installation ring which is arranged in the shell, wherein a heat absorption body is arranged inside the heat absorption body installation ring; a front-end plate with a daylight opening is arranged at the front end of the shell; an inner wall of the shell and a porous wall enclose an annular flow channel; and a glass cover plate covers the daylight opening. Converged sunlight penetrates through the glass cover plate, and is projected to different parts in the heat absorption body, gradually absorbed and converted into heat energy; cold air which comes upriver enters the annular flow channel, and then a part of cold air is blown to the inner wall of the glass cover plate to cool the glass cover plate; and all air flows flow through the heat absorption body, and are subjected to heat absorption and temperature rise and finally exhausted out of the heat absorber. By adoption of the volume heat exchange heat absorber for the solar heat generation system, the heat exchange, in a volume range, of the heat absorption body is realized, and the glass cover plate can be effectively cooled. The volume heat exchange heat absorber for the solar heat generation system has the characteristics of high heat exchange coefficient of the heat absorption body, low macroscopic heat stress, high reliability and the like.
